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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

Despite widespread recognition of a research–practice gap in multiple service sectors, less is known about how pre‐existing communication channels facilitate the flow of information between researchers and practitioners. In the current study, we applied an existing typology of brokerage developed by Gould and Fernandez (Sociol Methodol 19:89–126, 1989 ) to examine what types of brokerage facilitate information spread between researchers and educational practitioners. Specifically, we conducted semi‐structured interviews with 19 school administrators and staff in two public school districts regarding their experiences searching for information about instructional, health, and social skills programs. Using deductive content analysis, we found evidence of all five types of brokerage identified by Gould and Fernandez ( 1989 ). However, only three types of brokerage—gatekeepers, representatives, and liaisons—were involved in the flow of information between school administrators and researchers. Moreover, information transfer often occurred in longer chains that involved multiple, distinct types of brokerage. We conclude with the broad implications of our findings for narrowing the research–practice gap by improving researchers’ dissemination efforts and practitioners’ search for information. 相似文献
