Memory for child sexual abuse information: Simulated memory error and individual differences

Building on the simulated-amnesia work of Christianson and Bylin (Applied Cognitive Psychology, 13, 495–511, 1999), the present research introduces a new paradigm for the scientific study of memory of childhood sexual abuse information. In Session 1, participants mentally took the part of an abuse victim as they read an account of the sexual assault of a 7-year-old. After reading the narrative, participants were randomly assigned to one of four experimental conditions: They (1) rehearsed the story truthfully (truth group), (2) left out the abuse details of the story (omission group), (3) lied about the abuse details to indicate that no abuse had occurred (commission group), or (4) did not recall the story during Session 1 (no-rehearsal group). One week later, participants returned for Session 2 and were asked to truthfully recall the narrative. The results indicated that, relative to truthful recall, untruthful recall or no rehearsal at Session 1 adversely affected memory performance at Session 2. However, untruthful recall resulted in better memory than did no rehearsal. Moreover, gender, PTSD symptoms, depression, adult attachment, and sexual abuse history significantly predicted memory for the childhood sexual abuse scenario. Implications for theory and application are discussed.     

Developing a Brief Sensation Seeking Scale for Children: Establishing Concurrent Validity With Video Game Use and Rule-Breaking Behavior

Despite the importance of life-cycle models to sensation seeking research, past studies have typically focused on adolescents and adults. This is especially problematic for researchers studying the role of media use in the development of risky behaviors (e.g., violent video game consumption and aggressive behavior). To facilitate research with child populations, a brief sensation seeking scale for children (BSSS-C) is developed and validated with a sample of fourth, fifth, and sixth graders (N = 136). The BSSS-C is found to be internally reliable (α = .82) as well as a strong predictor of several risky child behaviors. Higher sensation seeking children were more likely to play video games, including violent subgenres (e.g., shooters), and to enjoy playing video games that contained specific acts of violence (e.g., weapon use). Higher sensation seekers were also more likely to engage in rule-breaking behavior, such as bringing prohibited cell phones to school. The results suggest that sensation seeking may be related to risky behavior at a very young age.     

Sensory curation: theorizing media use for sensory regulation and implications for family media conflict

ABSTRACT

Media sensory curation theory, introduced here, complements theories of informational, emotional, and relational media gratifications. Sensory curation theory conceptualizes media devices as tools people use to help maintain sensory regulation by simultaneously capturing and curbing sensory input within built and natural environments. This article explicates the theory and introduces the Child and Adult Media Sensory Curation Inventories (MediaSCIs), separate measures of child and adult media sensory behaviors and preferences. A survey of 789 parents and adult caregivers of children ages 3 to 14 revealed moderate to strong correlations between general sensory processing and media sensory curation, validating the MediaSCIs. Controlling usage time, child media sensory curation strongly predicted problematic child media use and moderately predicted adult–child media conflict, which was four times as frequent among adult–child pairs with high MediaSCI scores than with low MediaSCI scores.     

Neurobiological correlates of cognitions in fear and anxiety: A cognitive–neurobiological information-processing model

We review likely neurobiological substrates of cognitions related to fear and anxiety. Cognitive processes are linked to abnormal early activity reflecting hypervigilance in subcortical networks involving the amygdala, hippocampus, and insular cortex, and later recruitment of cortical regulatory resources, including activation of the anterior cingulate cortex and prefrontal cortex to implement avoidant response strategies. Based on this evidence, we present a cognitive–neurobiological information-processing model of fear and anxiety, linking distinct brain structures to specific stages of information processing of perceived threat.     

Alcohol Reverses Religion's Prosocial Influence on Aggression

The relationship between religion and violence is controversial. Discrepant findings exist between survey studies and the limited number of experimental investigations of religiosity's influence on aggressive behavior. We have attempted to resolve this discrepancy by addressing previous limitations in the literature and assessing a heretofore‐untested moderator of religiosity and aggression: alcohol intoxication. This investigation included a community sample of 251 men and 269 women randomly assigned to either an acute alcohol intoxication condition or a placebo condition. Participants completed a series of questions drawn from standardized instruments of religiosity and spirituality prior to competing on an aggression laboratory paradigm in which electric shocks were received from, and administered to, a fictitious opponent under the guise of a competitive reaction‐time task. Hierarchical regression analyses revealed a significant beverage‐by‐religiosity interaction. Religiosity predicted lower levels of aggression for participants in the placebo group and higher levels of aggression for intoxicated participants. Results indicated that high religiosity coupled with alcohol intoxication may be a risk factor for aggression. This novel finding may help to clarify previous discrepancies in studies of religiosity and aggression.     

Characterizing the Musical Phenotype in Individuals With Williams Syndrome

Williams Syndrome (WS), a neurodevelopmental genetic disorder, is characterized by peaks and valleys in mental function: substantial impairments in cognitive domains such as reasoning, arithmetic ability, and spatial cognition, alongside relatively preserved skills in social domains, face processing, language, and music. We report the results of a comprehensive survey on musical behaviors and background administered to the largest sample of individuals with WS to date (n = 118, mean age = 20.4), and compare the results to those obtained from a control group of typically developing normal individuals (n = 118, mean age = 20.9) and two groups of individuals with other neurodevelopmental genetic disorders, Autism (n = 30, mean age = 18.2) and Down Syndrome (n = 40, mean age = 17.2). Individuals with WS were found to be rated higher in musical accomplishment, engagement, and interest than either of the comparison groups, and equivalent on most measures to the control group. Compared to all other groups including the controls, the WS individuals displayed greater emotional responses to music, manifested interest in music at an earlier age, and spent more hours per week listening to music. In addition, the effects of music listening (whether positive or negative) tended to last longer in the WS group. A factor analysis extracted seven principal components that characterize the musical phenotype in our sample, and discriminant function analysis of those factors was able to successfully predict group membership for the majority of cases. We discuss the neurobiological implications of these findings.     

The Phenomenology of Hairpulling in College Students

This study examined the phenomenology of hairpulling in a large nonclinical college student sample. Given that hairpulling is conceptualized as occurring on a continuum of severity, we expected to inform the assessment and treatment of Trichotillomania (TTM) by examining hairpulling behavior across its range of presentation. Hairpulling occurred at a rate of 9.7%, while average age of onset was 13.57 years. Self-reported hairpulling styles were identified with 31.3% endorsing focused hairpulling, while 68.7% endorsed an automatic hairpulling style. The most commonly endorsed ritual was “examine the root (37.3%) while the scalp was the most frequently endorsed hairpulling site (49%). Eyelashes were more frequently endorsed as a pulling site by focused (43.8) compared to automatic (5.7%) hairpullers. The hairpulling environments most often endorsed were “while reading” and “while studying” (75%). Affective states were found to change across the pulling cycle in support of hairpulling serving in an emotion regulation capacity. Focused hairpullers endorsed significantly higher trait anxiety than automatic hairpullers. Depression scores (BDI) were elevated for hairpullers compared to non-hairpullers. Implications for assessment and treatment were discussed and directions for future research were provided.     

Publishing a Master’s Thesis: A Guide for Novice Authors

Publication of original research, clinical experiences, and critical reviews of literature are vital to the growth of the genetic counseling field, delivery of genetic counseling services, and professional development of genetic counselors. Busy clinical schedules, lack of time and funding, and training that emphasizes clinical skills over research skills may make it difficult for new genetic counselors to turn their thesis projects into publications. This paper summarizes and elaborates upon a presentation aimed at de-mystifying the publishing process given at the 2008 National Society of Genetic Counselors Annual Education Conference. Specific topics include familiarizing prospective authors, particularly genetic counseling students, with the basics of the publication process and related ethical considerations. Former students’ experiences with publishing master’s theses also are described in hopes of encouraging new genetic counselors to submit for publication papers based on their thesis projects.
