These findings suggest that positive perceptions of school climate may equip adolescents with psychological security that is instrumental to their peer affiliation, which ultimately decreases their risk of PIU. These findings point to malleable targets for prevention and intervention of adolescent PIU. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

We instead propose that discussions of human psychology may benefit from viewing ourselves not so much as rational animals but rather as the rationalizing animal. The current article provides evidence that rationalization is unique to humans and argues that rationalization processes (e.g., cognitive dissonance reduction, post hoc justification of choices, confabulation of reasons for moral positions) are aimed at creating the fictions we prefer to believe and maintaining the impression that we are psychologically coherent and rational. Coherence appears to be prioritized at the expense of veridicality, suggesting that distorted perceptions and appraisals can be adaptive for humans-under certain circumstances, we are better off understanding ourselves and reality not so accurately. Rationalization also underlies the various shared beliefs, religions, norms, and ideologies that have enabled humans to organize and coordinate their actions on a grand scale, for better or worse. We conclude with a discussion of the implications of this unique human psychological trait.

All APA standards and guidelines are required by Association Rule 30-8.3 to be revised at least every 10 years. The standards for training psychologists in the safe and responsible practice of prescribing psychotropic medication have been recently updated (Model Education and Training Program in Psychopharmacology for Prescriptive Authority, APA, 2019). A departure from the 1996 and 2009 versions of that document is that training may now be conducted at the doctoral level; however, a postdoctoral supervised clinical fellowship can only occur after the attainment of licensure as a practicing psychologist. Two novel features of the 2019 revision are the use of a competency-based model of learning and assessment, and increased emphasis on supervised clinical experiences in physical assessment and medication management. By the time of completion of their fellowships, practicing psychologists are expected to have clinical competence in the measurement and interpretation of vital signs; neurological examination; therapeutic drug monitoring; systems of care; pharmacology; clinical pharmacology; psychopharmacological research; and finally, professional, ethical, and legal issues. The updated standards were approved as APA policy in February 2019. This article briefly reviews the revision process and highlights the updates made in the most recent version of the standards.

Moreover, hippocampal damage impairs discrimination of spatial relations. We explore a mechanism by which this might occur modulation by the acetylcholine system. Acetylcholine enhances afferent input to the hippocampus and suppresses recurrent connections within it. This biases hippocampal processing toward environmental input, and should improve externally oriented, hippocampally mediated attention and perception. We examined cholinergic modulation on an attention task that recruits the hippocampus. On each trial, participants viewed two images (rooms with paintings). On "similar room" trials, they judged whether the rooms had the same spatial layout from a different perspective. On "similar art" trials, they judged whether the paintings could have been painted by the same artist. On "identical" trials, participants simply had to detect identical paintings or rooms. We hypothesized that cholinergic modulation would improve performance on the similar room task, given past findings that hippocampal representations predicted, and hippocampal damage impaired, behavior on this task. To test this, nicotine cigarette smokers took part in two sessions one before which they abstained from nicotine for 12 hours, and one before which they ingested nicotine in the past hour. Individual differences in expired breath carbon monoxide levels-a measure of how recently or how much someone smoked-predicted performance improvements on the similar room task. read more This finding provides novel support for computational models that propose that acetylcholine enhances externally oriented attentional states in the hippocampus.

The shelf lives of final dosage forms containing amorphous solid dispersions (ASDs) are often dictated by the rates of active pharmaceutical ingredient crystallization. Upon exposure to elevated RH, the higher anticipated water content near the surfaces of ASDs has the potential to substantially impact nucleation and growth kinetics relative to the bulk. However, quantitative assessment of these differences in growth rates is complicated by challenges associated with discrimination of the two contributions (supersaturation and molecular mobility) in ensemble-averaged measurements. In the present study, "sandwich" materials were prepared, in which sparse populations of ritonavir single-crystalline seeds were pressed between two similar ASD films to assess bulk crystallization rates.
