Neural Mechanisms Of The Rejection-Aggression Link, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall May 2018

Neural Mechanisms Of The Rejection-Aggression Link, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall

Social rejection is a painful event that often increases aggression. However, the neural mechanisms of this rejection–aggression link remain unclear. A potential clue may be that rejected people often recruit the ventrolateral prefrontal cortex’s (VLPFC) self-regulatory processes to manage the pain of rejection. Using functional MRI, we replicated previous links between rejection and activity in the brain’s mentalizing network, social pain network and VLPFC. VLPFC recruitment during rejection was associated with greater activity in the brain’s reward network (i.e. the ventral striatum) when individuals were given an opportunity to retaliate. This retaliation-related striatal response was associated with greater levels of …

Atypical sensory perception is one of the most ubiquitous symptoms of autism, including a tendency towards a local-processing bias. We investigated whether local-processing biases were associated with global-processing impairments on a global/local attentional-scope paradigm in conjunction with a composite-face task. Behavioural results were related to individuals' levels of autistic traits, specifically the Attention to Detail subscale of the Autism Quotient, and the Sensory Profile Questionnaire. Individuals showing high rates of Attention to Detail were more susceptible to global attentional-scope manipulations, suggesting that local-processing biases associated with Attention to Detail do not come at the cost of a global-processing deficit, but …


The Contributing Factors To Adolescent Depression, Josie H. Lee Apr 2018

The Contributing Factors To Adolescent Depression, Josie H. Lee

Independent Study Project (ISP) Collection

Objective: This paper reviews individual, familial, peer, and societal factors influencing adolescent depression in developed countries. Background: Depression usually onsets at adolescence and contributes to high DALYs. Since depression is treatable, efforts should be made to reduce its prevalence and effect. Methods: The research consisted of looking at literature relevant to the topic and age group and conducting interviews with experts who know about and have worked with adolescent depression. Discussion: Adolescents begins at the onset of puberty, allowing different biological factors such as genetics, stress of puberty, and cognitive changes to increase vulnerability to depression. Adolescents who had substance …


Reproductive Steroids And Adhd Symptoms Across The Menstrual Cycle, Bethan A. Roberts, Tory Eisenlohr-Moul, Michelle M. Martel Feb 2018

Although Attention-Deficit/Hyperactivity Disorder shows (ADHD) male predominance, females are significantly impaired and exhibit additional comorbid disorders during adolescence. However, no empirical work has examined the influence of cyclical fluctuating steroids on ADHD symptoms in women. The present study examined estradiol (E2), progesterone (P4), and testosterone (T) associations with ADHD symptoms across the menstrual cycle in regularly-cycling young women (N=32), examining trait impulsivity as a moderator. Women completed a baseline measure of trait impulsivity, provided saliva samples each morning, and completed an ADHD symptom checklist every evening for 35 days. Results indicated decreased levels of E2 in the context of increased …

Background Despite the large number of studies and reviews available, the evidence regarding the policy determinants of physical activity (PA) is inconclusive. This umbrella systematic literature review (SLR) summarizes the current evidence on the policy determinants of PA across the life course, by pooling the results of the available SLRs and meta-analyses (MAs). Methods A systematic online search was conducted on MEDLINE, ISI Web of Science, Scopus and SPORTDiscus databases up to April 2016. SLRs and MAs of observational studies investigating the association between policy determinants of PA and having PA as outcome were considered eligible. The extracted data were …


Sexual Coercion, Drinking To Cope Motives, And Alcohol-Related Consequences Among Self-Identified Bisexual Women, Michelle L. Kelly, Sarah J. Ehlke, Robin J. Lewis, Abby L. Braitman, Wendy Bostwick, Kristin E. Heron, Cathy Lau-Barraco Jan 2018

Psychology Faculty Publications

Background: Given higher sexual victimization and greater alcohol use among bisexual women, a critical public health challenge is to understand within-group variation that may heighten or explain these associations in bisexual women. Objectives: The present study tested a moderated-mediation model in which sexual coercion was hypothesized to be associated with alcohol-related consequences via drinking to cope motives in self-identified bisexual women who reported at least occasional binge drinking. Negative affect was hypothesized to moderate the sexual coercion-drinking to cope motives association. Methods: Participants were a community sample of 107 self-identified bisexual women (age M = 20.97, SD = 2.11) who …


Independent And Interactive Associations Of Negative Affect, Restraint, And Impulsivity In Relation To Binge Eating Among Women, Tyler B. Mason, Kathryn E. Smith, Jason M. Lavender, Robin J. Lewis Jan 2018

There is growing recognition that impulsivity may serve as an underlying risk factor for binge eating. In addition, the association of impulsivity with binge eating may be moderated by other affective and cognitive risk factors. This study examined independent and interactive associations of negative affect, dietary restraint, and facets of impulsivity with binge eating. A diverse sample of 566 undergraduate women completed online questionnaires of study variables. Results revealed a three-way interaction of negative affect, dietary restraint, and attentional impulsivity in relation to binge eating. Women who were high on each of these three variables reported the greatest levels of …
