Depression is a debilitating disorder with established prevalence and detrimental impact on the economy. Ketamine is a fast acting and long lasting treatment for depression, including treatment resistant patients. The mechanism(s) behind ketamine's effects is unknown. Thus, this study assessed the effects of acute ketamine treatment on a new chronic stress paradigm using C57BL/6J and CD1 aggressor adult male mice. The C57BL/6J mice were assigned to three groups: emotional stress (ES),...
Show moreDepression is a debilitating disorder with established prevalence and detrimental impact on the economy. Ketamine is a fast acting and long lasting treatment for depression, including treatment resistant patients. The mechanism(s) behind ketamine's effects is unknown. Thus, this study assessed the effects of acute ketamine treatment on a new chronic stress paradigm using C57BL/6J and CD1 aggressor adult male mice. The C57BL/6J mice were assigned to three groups: emotional stress (ES), physical stress (PS), and control (CON) conditions. The mice in the PS condition received social defeats, while the ES mice witnessed the defeats, for 10 consecutive days, 10 minutes each day. Twenty-four hours after the last stress session, the mice were injected with either saline or ketamine (0.20 mg/kg) one hour before a social interactions test was conducted to assess whether ketamine could rescue deficits in interaction elicited by chronic stress. Mice in the PS condition showed significantly reduced interaction time when the target was present, whereas the ES-exposed mice displayed only similar trend, regardless of drug treatment. Time spent in corners varied as a function of stress exposure but not drug treatment, with the ES- and PS-exposed mice spending significantly more time in the corners when the target was present. With the exception of the ketamine-treated controls, mice receiving saline displayed reduced interaction times when compared to a group of non-injected controls regardless of stress condition. These finding suggest that ketamine was unable to alleviate the stress-induced deficits in social interaction, however, acute ketamine may be beneficial in alleviating the effects of acute stress.

One active area of psycholinguistics research seeks to determine whether language acquisition occurs through domain-specific processes or domain-general processes. In other words, are the cognitive resources dedicated to language learning specific to language, or are they part of a more general learning mechanism?

Show moreOne active area of psycholinguistics research seeks to determine whether language acquisition occurs through domain-specific processes or domain-general processes. In other words, are the cognitive resources dedicated to language learning specific to language, or are they part of a more general learning mechanism? One intriguing strategy for investigating this question is through the comparative use of language and music: each is a complex system in which basic auditory elements are combined in hierarchical sequences governed by abstract rules. To understand either language or music, a person must learn these syntactic rules and generalize them to new situations. This study used an artificial grammar construct to investigate whether people learn and process musical and linguistic syntax similarly, and whether there is a correlation between a person's ability to learn complex grammatical systems in multiple modalities. The effect of previous musical experience on sequence learning was also examined. Results showed virtually no correlation between the three implicit learning tasks, suggesting that there is no domain-general implicit learning ability.

Show moreLow levels of social support in relationships are an important indicator of the risk of the development of depression in adulthood. This study investigated how family, friends, and romantic relationships affected the prevalence of depressive symptoms. This study tested the hypothesis that family relationships would not have significant effect on depression when the effect of romantic relationships and friendships are controlled. Hierarchical multiple regression analyses of responses from participants from the Transition Wave II questionnaire revealed that lower support from family relationships and romantic relationships was significantly associated with higher depression scores, while support from friendships was not. When controlling for support from friendships and relationships, romantic relationships had the strongest effect. This suggests that in adulthood, one's romantic relationships are more indicative of depression than friendships or family relationships.

Show moreThe study of relationship failure and adjustment has fueled the majority of research with the topic of divorce. This study attempts to replicate the findings in divorce studies on attributions and adjustment using 188 college-age premarital couples who have ended a committed romantic relationship within six weeks of assessment. Different causal attributions for relationship failure were inspected for different levels of adjustment. Adjustment was assessed by examining the variables of loneliness, depression, and alcohol use. We further examined for gender differences in adjustment by examining men and women separately. Using structural equation modeling, we analyzed adjustment at the initial time of their breakup and again several weeks later to assess how well they were adjusting over time. We found that attributions did not significantly predict adjustment for men and women together, but became closely associated with alcohol use. Specifically, individuals who reported the relationship attribution drank more alcohol. Men drank significantly more alcohol than women at both times in the assessment. In the overall adjustment examination, regardless of attributions, men appeared to have poorer adjustment than women over time. Though there were gender differences, the finding did not reach significance.

Show moreIndividuals tend to exhibit implicit, cognitive associations between numbers and space. Small numbers become associated with the left side of their bodies and large numbers with the right side of their bodies. This "spatial-numerical association of response codes" (SNARC) provides evidence that individuals tend to sort their spatial orientations along a mental number line. Since most cultures promote the use of finger-counting as a universal means for learning to work with numbers, it is believed that the directionality of finger-counting (from left to right or right to left) affects the way we link numbers and space in adulthood. To assess finger-directionality, past studies have utilized self-report questionnaires; however, recent findings have suggested a new measure that classifies finger-directionality by observing natural finger-counting habits and circumvents the biases associated with self-report. In the current study with a sample of ninety-four college students, when using self-report to categorize counting habits, we found a statistically significant difference between groups; right-starters displayed the SNARC effect while left-starters did not. However, when using observed behaviors to categorize counting habits, we did not find a statistically significant difference between left and right starters. These findings suggest that finger-counting hands do not predict the SNARC effect, which is consistent with the flexibility of the effect itself.

Show moreNicotine use during adolescence is associated with the development of many debilitating pathologies in adulthood such as anxiety and depression. Adolescence is a time of many social pressures and biological changes occurring within the brain and body. Therefore, studying the effects of nicotine exposure during adolescence on stress and subsequent sensitivity to nicotine itself is of great interest. To examine these questions I designed experiments to assess both short (i.e., 24 hours after treatment) and long-term (i.e., four weeks after treatment) behavioral consequences of nicotine (0.32 mg/kg) exposure during adolescence (i.e., postnatal days 35-49) in C57/BL6 male mice by exposing them to social-defeat stress, social interaction, and subsequent preference for nicotine. Nicotine-treated mice in the short-term condition displayed avoidant behaviors and a preference for the lowest concentration of nicotine (5 mg/l). Interestingly, the nicotine-treated mice in the long-term condition displayed enhanced social avoidance as well, with a similar preference for the low concentration of nicotine. These results indicate that exposure to nicotine during adolescence influences social interaction behavior and increases preference for nicotine, findings that last into adulthood. Future studies using different stressors and a complete nicotine dose-response may reveal further insight into how nicotine affects this age group and its long-lasting consequences. The work presented here increases our understanding of the effects of nicotine exposure during adolescents and the later effects, which may develop over time.

Show morePostpartum depression affects up to 15% of women, is highly disabling, but under-addressed in obstetrics settings. The objectives of this study were to examine the characteristics of women seeking obstetrical services in a health system serving primarily Medicaid patients, and to examine biopsychosocial predictors of postpartum depression (PPD) that may be routinely assessed during obstetrical visits. Specific variables examined included a previous history of depression, maternal behavioral and health factors, and pregnancy complications. Multivariate analyses showed that prepartum depression, white race, and street drug use were significantly associated with postpartum depression. These findings can be used to help obstetricians target women with these risk factors and get them help before the onset of postpartum depression.

Show moreDespite the high prevalence of suicide attempts amongst individuals with obsessive-compulsive disorder (Kamath et al., 2007), the relationship between OCD and suicidality is under researched and studies have reported contradictory results. In the present project, we examine the connection between OCD symptoms and suicidal behavior through the lens of the Interpersonal Theory of Suicide (Joiner, 2005). In particular, we examine the role of painful and provocative experiences specific to OCD – specifically, painful compulsive behaviors – that may enhance the acquired capability for suicide. We predicted that OCD symptoms that elicit physical pain (i.e. compulsive behaviors) would be associated with suicidality and acquired capability. Additionally, we predicted that depressive symptoms would be a partial mediator between OCD and suicidal behavior. Our findings suggest that there is a significant, positive association between many OCD symptoms and suicidality. We did not find evidence for the role of compulsivity as a factor increasing the acquired capability or suicidal symptoms, when controlling for OCD and depressive symptoms. In line with our hypothesis, depressive symptoms partially mediated the relationship between OCD symptoms and suicidality. Implications and future directions are discussed.

Show moreSocial exclusion can threaten a person's need to belong, need for control, and need to feel that one's life has meaning. The current research investigated how rejected people reintegrate themselves into new social groups. In this experiment, rejected (and non-rejected control) participants were given the opportunity to join an ostensibly new experiment in which they would complete a group activity with two other participants. I then measured their motivation to attain a powerful or subordinate position within the group. While pursuing a position of power in a new group may allow rejected people to restore control and meaning, subordinate positions in a new group may be better suited to restore belonging. The results were consistent with the latter possibility. That is, rejected participants preferred a subordinate position more than non-rejected participants, especially if the subordinate position allowed a high level of involvement in the group activity. These results suggest that rejected people interacting with a new group prefer roles in which they can contribute to the group goal without taking responsibility for group outcomes.

Show moreThe purpose of the Cross Cultural Music Therapy thesis is to record how music functions therapeutically within Spanish, Irish, English and American cultures. Within each culture it involves the comparison of professional protocols, political and cultural implications, cultural music preferences, client population served, choice of music therapy approaches and treatment, educational focus, and specializations. A standard series of in-depth interview questions regarding international music therapy concepts was used to identify and expand upon the interventions and objectives that are being practiced across man cultural and geographical boundaries. Detailed, qualitative records of interviews and observations were used to compare and contrast how music is used as therapy across different cultures. Through the research and writing of Cross Cultural Music Therapy the discovery of universal passions and patterns of thinking for music therapist across the world have been shared. The choice in practicing principles, education level, qualifications, and geographical location may differ but the focus and drive for the chosen career field of music therapy has maintained a universally high standard. As the field of music therapy research and practice rapidly grows it is of vital importance that we evaluate the universal truths of music and therapeutic intention by looking beyond our own circle of influence and into those circles we seldom are able to explore. Spending one hour looking through someone else's eyes about the very subject you are most passionate about may be more beneficial in shaping your personal practice than months spent in a class room reading about it in print.

Show moreExternalizing, a factor related to a deficit in impulse control, has been widely associated with reductions in the amplitude of the P300 event-related potential (ERP) component. Recently, time-frequency (TF) signal processing approaches have been able to index separable components underlying P300 activity, and provide incremental prediction for externalizing above traditional time-domain approaches to measuring P300 (Gilmore et al., 2010). Next, shared variance from time-domain measures of P300 from different tasks and the error-related negativity demonstrated incremental prediction for externalizing above single tasks (Nelson et al., 2010), consistent with the idea of a multivariate phenotype (Iacono, Carson, & Malone, 2000). The current study integrates these approaches by using TF analysis to extract multiple overlapping TF components from each task, and then apply factor analysis across the components from all the tasks to derive latent task-based brain activations. TF amplitude (TF-AMP) and inter-trial phase synchrony (TF-ITPS) measures were assessed. Results of the factor analysis suggested a two-factor solution, which corresponded to the well-known theta (3-7 Hz) and delta (0-3 Hz) frequency ranges in both measures. Solutions with a higher number of components were assessed as well, providing greater time and frequency detail to the solutions. Finally, the TF-AMP and TF-ITPS measures were assessed with regard to externalizing, and did evidence incremental prediction above traditional time-domain measures.

Show moreSimulator sickness is a common occurrence when humans navigate virtual environments; some proportion of the population will experience nausea, disorientation, headache, and a number of other negative symptoms during and after an interaction with a flight simulator, driving simulators, or first-person video game. While there are a number of theories behind the causes of simulator sickness, including theories related to posture stability and body movement, there are still no accepted explanations for why some people are more susceptible to sickness compared to others. Some theories suggest that eye and head movements, age, gender, and simulator scenario properties (e.g., number of turns) may have an effect on simulator sickness. We took advantage of already collected eye movement, simulator sickness, and demographic data and explored possible correlations between simulator sickness and a variety of factors, such as the ones that were mentioned above. Of particular interest was whether eye tracking data might predict sickness severity. Results indicated that gender was significantly related to simulator sickness (females reporting greater sickness), and there was a trend for a relationship between age and simulator sickness, with increased age being specifically related to general discomfort and symptoms of vertigo. Contrary to predictions, eye scanning parameters were not significantly related to simulated sickness. Study limitations and future directions are discussed.

Show moreVisually sparse and abstract laboratory paradigms are often used to study visual attention and attention capture. Do the factors found to influence the allocation of attention in these studies also predict distraction in more complex real-world scenes? We explored this question using an attention capture paradigm modeled after driving a driving scene. Anecdotally, the flash that accompanies Red Light Running Cameras (RLRC) has been reported to be distracting. An Inhibition of Return (IOR) paradigm was used to test if RLRC flashes in simulated driving scenes capture attention. After attention is allocated to an area, IOR discourages future attention shifts to that same area, thus IOR serves as a reliable marker of spatial attention. In two experiments, participants were slower to respond to the brake lamps of a vehicle when a RLRC flash occurred nearby, and were also slower at initiating eye movements to brake lamp signals (IOR effects). Results suggest that attention can be misdirected as a result of RLRC flashes and demonstrate that findings from simple laboratory paradigms can predict the allocation of attention in complex settings that are more familiar to observers. Despite clear evidence for the capture of attention, additional study is necessary to better understand the effect RLRC flashes may have on driving performance.

Show moreEach year in the United States hundreds of billions of dollars are donated to charitable causes by individuals, thus it is important to understand factors that contribute to donating behavior to maximize public good. This study examined how attention might be captured by donation-relevant information on the web. The basic attention literature suggests that information presented in a unique color should capture attention reliably, even when this information is completely irrelevant to the task at hand. However, other research suggests that observers have a large degree of top-down control over their attention (knowledge and intention primarily drive attention). We contrasted these two views in a simulated web-surfing task in which participants searched for specific information. Donation-relevant information was presented either in the website's default text color or in a unique color. Contrary to predictions, uniquely colored links did not capture attention as measured by eye movements. Furthermore, when participants did fixate this information, they moved their eyes away from it quicker when it was presented in a unique color. Strong top-down control of attention was observed since participants almost never fixated donation information when they knew the information they were looking for would be presented elsewhere. Findings support models of attention that propose that top-down knowledge primarily determines where attention goes and how long attention stays at a location. These findings have important implications for donation campaigns, online advertising, and the theories of attention capture.

Show moreSalient visual features have been known to capture attention, but there is disagreement regarding why these features capture attention (because of their bottom-up salience/uniqueness or the goals of the observer). To explore whether attention capture is truly a bottom-up, stimulus-driven, and automatic effect, Boot, Brockmole, & Simons (2005) added an auditory task to a traditional attention capture paradigm. In single task conditions, they found that onsets (objects that appear suddenly) and color singletons (items of a unique color compared to the items around them) captured attention. However, when participants also had to listen to the auditory task, the degree to which these distractors captured attention changed (onsets capture was eliminated while color singleton capture increased). These findings challenge the notion that capture is stimulus-driven and automatic; the search display was exactly the same in single and dual-task situations. However, it was puzzling why onsets decreased in their ability to capture attention while color singletons increased under the same dual-task conditions. Boot, Brockmole, & Simons (2005) proposed a transience hypothesis: transient singletons like an onset require cognitive resources to be recognized as being unique, while sustained distractors such as color-singletons required cognitive resources to suppress. We tested this hypothesis with onset distractors that were either the same as the other distractors in the display, or onset distractors that also had a unique shape. Contrary to predictions, neither had the ability to capture attention under dual-task load. Results do not support stimulus-driven accounts of attention capture. Theoretical and practical significance is discussed.

While there is an abundance of research focusing on the lack of women in science, technology, engineering, and mathematics (STEM) fields, research has yet to focus on how pluralistic ignorance plays a role in women's avoidance of these fields for study and a career. In the present project, I examine the relationships between the stereotypes that individuals hold and the stereotypes individuals believe their friends hold regarding computer programmers and an individual's interest in computer programming. It was predicted all of the participants would engage in pluralistic ignorance regarding these stereotypes which would affect interest in computer programming. Additionally, to account for the gender gap, it was predicted that women would engage in pluralistic ignorance to a greater degree than men. Alternatively, it was predicted that men and women would engage in the same level of pluralistic ignorance, but this error would have a larger impact on women's interest in computer programming. A marginally significant trend was found for women perceiving that their friends hold more stereotypical views than men. Additionally, a significant correlation between men's perceptions of their friends' stereotypes was found and men's interest. I did not find any significant relationship between women's views or the views they believe their friends hold and women's interest in computer programming. Implications and future directions are discussed.

La Rosa, Nikki L., Department of Psychology
- Abstract/Description
-
Entering college, the majority of freshmen experience some sort of feelings of loneliness during the beginning of the transition to a new environment.

Show moreEntering college, the majority of freshmen experience some sort of feelings of loneliness during the beginning of the transition to a new environment. Loneliness can lead students to have a multitude of negative effects, including poorer physical health and depression. This study examined whether shyness and geographical distance from college students' permanent residence would be associated with feelings of loneliness. Participants were 93 freshmen at a large southeastern university. Results indicated that shyness was associated with the feelings of loneliness, while distance was not. Contrary to predictions, the interaction of these two variables was not a significant predictor of loneliness. Implications of the findings for enhancing freshman adjustment are discussed.

The purpose of the current study was to determine whether memory for associations between parts of an event that is negative depends on which negative emotion it is, particularly disgust. Participants were instructed that they would see pictures of locations, revealed one by one. Participants were told that they would be presented with one of three scenarios in each of the locations.

Show moreThe purpose of the current study was to determine whether memory for associations between parts of an event that is negative depends on which negative emotion it is, particularly disgust. Participants were instructed that they would see pictures of locations, revealed one by one. Participants were told that they would be presented with one of three scenarios in each of the locations. There were three conditions (disgust, reward and neutral) and after viewing location pictures, participants were handed a clear plastic bag with a piece of candy in it. In the neutral condition the was candy alone, in the reward condition the candy was with a ten dollar bill and in the disgust condition the candy was with a feminine pantyliner stained with fake blood from a costume store. Memory for location picture/candy combination was assessed with an associative recognition test. Participants had to indicate whether the pairs seen were intact or rearranged. Recall was also assessed; participants were asked to indicate what treatment went with each candy. Brief questionnaires (DPSS-R and VOCI) were used to assess disgust sensitivity. Disgust did not prove to increase participant associative recognition of location picture/candy pairs. Those higher in disgust were less likely to recall pairs in the disgust treatment. Effect of emotion on recall for what appeared in the bag with the candy was not significant overall. The current study illustrates that personality factors and individual differences are important factors when analyzing effects of disgust on memory. How sensitive someone is to disgust may impact memory.

Research has found that individuals with Obsessive-Compulsive Disorder (OCD) report heightened levels of responsibility for harm when compared to anxious and non-clinical control subjects (Cougle, Lee, & Salkovskis, 2007). Responsibility for harm is hypothesized to have a causal role in the disorder, but inflated responsibility may also be a consequence of OCD symptoms.

Show moreResearch has found that individuals with Obsessive-Compulsive Disorder (OCD) report heightened levels of responsibility for harm when compared to anxious and non-clinical control subjects (Cougle, Lee, & Salkovskis, 2007). Responsibility for harm is hypothesized to have a causal role in the disorder, but inflated responsibility may also be a consequence of OCD symptoms. The aim of the current study was to test the effects of repeated checking, a common compulsion for individuals with OCD, on responsibility for harm appraisals. Following the completion of several self-report measures, including an instrument assessing threat estimation and responsibility beliefs, non-clinical participants (N=101) were randomized into one of three conditions: 1) 20 checks on a functional, electric stove, 2) 20 checks on four water bottles, or 3) a combination 10 water bottle checks followed by 10 stove checks. Ratings of responsibility for harm related to the stove were taken at baseline and following task completion. Moderator analyses indicated that, among participants with lower threat estimation and responsibility beliefs, both stove checking conditions experienced greater responsibility for harm following the checking task compared to the water bottle checking condition. Among those participants high in threat estimation and responsibility, no differences in post-task responsibility ratings were found between conditions. Overall, these findings suggest that inflated responsibility beliefs may be both a cause and a consequence of compulsive checking.

Show moreMood disorders have become the most prevalent mental health disorder affecting US adults today. Exposure to emotional or physical stress can increase the likelihood of developing a mood disorder and thus is detrimental to the population. The hypothalamic-pituitary-adrenal (HPA)-Axis functions in the stress response and is suggested to be involved in the manifestation of mood disorders. However, the mechanism(s) underlying the stress response are not completely understood therefore preclinical studies are indispensable. Here, I exposed male adolescent (postnatal day [PD] 30-40) C57/BJ mice to bouts of physical or emotional stress for ten consecutive days, and assessed HPA-Axis functioning by analyzing plasma corticosterone (CORT) levels at various time points after stress exposure. Mice exposed to physical and emotional stress displayed elevated plasma CORT levels 24 and 48 hours after stress exposure. The changes in HPA function were accompanied by behavioral deficits (i.e., increased anxiety-related behavior and social avoidance/withdrawal) 1 month after stress exposure. These results suggest unique involvement of the HPA-Axis in the manifestation of mood-related disorders, however complete mechanisms are not fully understood and continued research in this area is necessary.

What accounts for the stark changes in emotion, cognition, and behavior in women during the premenstrual phase of the menstrual cycle?

Show moreWhat accounts for the stark changes in emotion, cognition, and behavior in women during the premenstrual phase of the menstrual cycle? I hypothesize that, in addition to the effects of hormones, a lack of self-control may account for these changes. The metabolically expensive activity of the premenstrual phase diverts energy from metabolically expensive self-regulatory processes, making the use of self-control more difficult. In this article, I experimentally test this hypothesis with the dual-task paradigm common to self-control research. That is, participants perform one task that requires and depletes self-control—the Stroop task—followed by another task that requires self-control—a dependent measure. I randomly assigned 34 undergraduate women to either a control or ego depletion condition and to participate either during the premenstrual or postmenstrual phase of their menstrual cycles. I measured total affect, critical thinking, and aggression. Results, while preliminary, are consistent with the hypothesis that self-control depletion is not only linked to emotional, cognitive, and behavioral changes in the premenstrual phase, but also exaggerates these changes. I offer an explanation for my findings and conclude with a discussion of future work and implications.

Show moreResearch has identified clinical perfectionism to be a risk factor for a variety of forms of psychopathology. It is a personality construct characterized by high personal standards, negative self-evaluations, and preference for subjective states of perfection. Research has shown that there is a unique relationship between perfectionism and feelings of incompleteness, one of the two dimensions that underlie overt symptoms subtypes of obsessive-compulsive disorder (OCD). Uncomfortable sensations of things being not "just right" drive OCD symptoms in the incompleteness dimension. The current studies aimed to further evaluate the relationships between perfectionism and incompleteness. Study 1 utilized a small sample of participants with elevated feelings of incompleteness, while Study 2 utilized a large, unselected student sample. Self-report measures and in vivo assessments of visual and tactile incompleteness were completed in both studies, and task-related perfectionism in response to arranging clutter was additionally evaluated in Study 1. We hypothesized that dispositional and task-related perfectionism would be related to both self-report and behavioral assessments of incompleteness. In both studies, dispositional perfectionism was significantly correlated with feelings of incompleteness. In Study 1, dispositional perfectionism was related to tactile urge to straighten stimuli, as was dispositional incompleteness with the dispositional perfectionism subdomains "doubts about actions" and "personal standards." In Study 2, dispositional perfectionism was related to visual and tactile discomfort, as well as urge to straighten the visual and tactile stimuli; dispositional incompleteness was correlated with dispositional perfectionism. Clinical implications of the relationship between perfectionism and incompleteness are discussed.

Many studies support the view that visual attention is captured by salient or unique objects, whether we intend to pay attention to these objects or not. While it has been proposed that capture is automatic and driven purely by properties of the physical stimulus, recent research has suggested that previous experience also contributes to the degree to which an object captures attention. Hickey, Chelazzi and Theeuwes (2010a, 2010b, 2011) find that after a successful search for an object...
Show moreMany studies support the view that visual attention is captured by salient or unique objects, whether we intend to pay attention to these objects or not. While it has been proposed that capture is automatic and driven purely by properties of the physical stimulus, recent research has suggested that previous experience also contributes to the degree to which an object captures attention. Hickey, Chelazzi and Theeuwes (2010a, 2010b, 2011) find that after a successful search for an object followed by a high reward, distraction by a unique but irrelevant item is reduced during the next search episode. However, when a feature associated with the target of search after a high reward becomes associated with an irrelevant distractor, capture is increased. Hickey and colleagues propose this reward modulation of attentional selection as a way we can generally learn what to pay attention to and what to ignore over time. The aim of this thesis is to further explore the time course of these reward effects to observe whether they grow over time, and whether they are robust to intervening tasks, which should be true if they represent a useful mechanism through which we learn how to allocate our attention. Surprisingly, unlike previous studies, we found that high reward did not prime the color of the search target, but instead primed its spatial location. Possible reasons for this divergent finding are discussed.

Show moreFindings in research studies indicate that children's language development greatly benefits from characteristics of conversational input from adults such as parents and teachers. With the use of live observations this study was designed to examine factors thought to indicate a higher propensity with which preschool teachers would be to respond to child-initiated speech. In this study, descriptive statistics and correlations were conducted to explore the relationships between the variables proposed. There were a total of 23 participating preschool teachers. Two to three separate hour long observations were conducted for each classroom during nondirective activities such as centers time (i.e. free play), snacks (i.e. lunch), and transitions. Data was collected through a standardized measure of teacher-child conversations, a chaos and classroom management scale, and teacher background surveys. Given this study's results the proposed hypotheses were not supported. Teacher-child ratio were not positively correlated with teacher response to child-initiated speech and classroom management quality and chaos level only had showed partial correlations. Limitations of this study and proposals for future research are discussed in the document.

Results suggest that backwards chaining is the ideal chaining method for preschoolers when learning how to tie a shoe. Future research should be aimed at generalizing this procedure to a shoe they are wearing, and determine if the children show the same preference for this procedure on other self care tasks.

Differential components of heart rate reactivity (HR) were hypothesized to reflect orienting responses and engagement in a defensive (fight or flight) motivational state. The Externalizing Spectrum Model (Krueger et al., 2002; Krueger & Markon, 2005) posits clinical problems involving excessive substance use and antisocial behavior are specific manifestations of a general propensity towards deficient impulse control (disinhibitory proneness). The current study expands upon previous research by evaluating the association between disinhibitory proneness (operationalized through scores on the Externalizing Spectrum Inventory; Krueger, Markon, Patrick, Benning, & Kramer, 2007) and cardiac reactivity in a community sample of twins (N=508). Findings provide support for reduced cardiac reactivity in individuals scoring highly on disinhibitory proneness.

In the beginning of the experiment, participants were required to complete the Big Five Personality Test and the State Trait Anxiety Inventory (STAI). Following this, participants were randomly assigned one of two conditions (low stress, high stress). In the low stress condition, participants completed simple subtraction problems, whereas in the high stress condition participants completed complex long-division problems. Calculators and electronic calculating devices were not permitted. After participants completed the math problems they filled out an alternative version of the STAI. It was hypothesized that individuals who scored high on the trait, neuroticism, would produce higher scores of anxiety on the STAI following the experimental manipulation than would participants who scored low or not at all on the trait. It was found that participants high in neuroticism, produced greater trait anxiety scores, regardless of the experimental manipulation, suggesting that even minor stressful events initiate anxiety in individuals high on this trait.

The focus of this data analysis is to examine a possible interaction between age and depression on episodic memory performance. A multiple regression approach was used to analyze previous data from CREATE I which includes a sample size of 1,204 participants between the ages of 18-91. Age and depressive affect had significant negative effects on episodic memory performance, and these two factors interacted, showing that depressive affect had little impact at young ages but increasingly affected those at older ages. Results suggest that interventions to reduce depressive affect in older populations may also contribute to improved episodic memory performance.
