Cognitive Load Theory,Element Interactivity,and the Testing and Reverse Testing Effects

Summary: The testing effect arises when learners who are tested rather than relearning material obtain superior scores on a final test than those who relearn. Based on cognitive load theory, six experiments examined whether the effect was evident under low or high element interactivity (a measure of complexity) conditions. Students learning to write types of text were participants. In all experiments, effects on a final common test of two presentations were compared with a single presentation followed by a preliminary test. The testing effect on immediate tests was larger and more likely using lower element interactivity materials. A reverse testing effect was likely on immediate tests tapping higher element interactivity material but possibly eliminated by using a delayed test. Copyright © 2017 John Wiley & Sons, Ltd.     

“I was and still am”: Narratives of Bisexual Marking in the #StillBisexual Campaign

This research investigated narratives of bi-erasure and bisexual marking by considering 53 video confessionals associated with the #StillBisexual campaign. #StillBisexual is a web-based campaign that targets myths about bisexuality and promotes bisexual identity visibility. Thematic analysis was conducted to identify emergent themes regarding the ways that individuals mark and make known their bisexuality. Three major themes of bisexual demarcation emerged including the enduring nature of bisexuality, defining bisexuality, and defining the self as a bisexual being. Discussion focuses on describing bisexual marking approaches by #StillBisexual participants and by analyzing the way bisexual demarcation challenges assumptions of monosexism and cisgenderism inherent to cultural conceptualizations of sexuality.     

Deculturation: its lack of validity

Deculturation's history as well as its use in the social science literature is reviewed and its construct validity questioned. According to J. W. Berry (1980), deculturation results when members of nondominant cultures become alienated from the dominant culture and from their own minority society. A reported consequence of deculturation is increased stress and psychopathology for the individuals involved. Deculturation's basic assumption that there can be culture loss without replacement is critically assessed. In particular, the idea that members of nondominant groups can become deculturated, devoid of any culture, is challenged.     

Automatic activation of Yellow Peril Asian American stereotypes: effects on social impression formation

The authors randomly assigned 69 undergraduates to 1 of 2 perceptual priming conditions involving 80-ms flash words presented on a computer screen to activate information processing outside of conscious awareness. In the high-prime condition, the authors exposed participants to stereotype words associated with the Yellow Peril view of Asian Americans. The authors exposed participants in a low-prime condition to neutral words. All participants then read a vignette and evaluated its protagonist on several social dimensions. Results indicated that the priming procedure effectively biased participant evaluation of the vignette target, but only on items closely linked to Asian Americans. Contrary to predictions, however, participants in the high-prime group rated the target less Asian than did their low-prime group counterparts, an apparent reversal of the expected priming effect. The authors discussed theoretical implications.     

A poor metabolizer for cytochromes P450 2D6 and 2C19: a case report on antidepressant treatment

Scientific literature has never described a poor metabolizer for both the cytochrome P450 (CYP) 2D6 and the CYP 2C19. They are expected to be rare (<1% in different ethnic groups) and prone to adverse drug reactions with many antidepressants. In an ongoing pharmacogenetic study, after genotyping 1,576 subjects in three Kentucky state hospitals we have found one poor metabolizer for both CYP 2D6 and CYP 2C19, which corresponds to a prevalence of 0.06% (95% CI 0.01 to 0.36). The naturalistic antidepressant treatment of this poor metabolizer for both enzymes is described in this article. As genotyping reaches clinical practice, it will be interesting to prospectively establish whether mirtazapine is a reasonable choice as an antidepressant for these patients, as the data and this case suggest.     

Modulation of working, short- and long-term memory by nicotinic receptors in the basolateral amygdala in rats

Male Wistar rats were exposed to one-trial step-down inhibitory avoidance training using a 0.5 mA footshock. Through bilaterally implanted indwelling cannulae, they received bilateral 0.5 microL infusions of saline, mecamylamine (1.0 or 10.0 microg/side), or nicotine (0.6 or 3.0 microg/side) into the basolateral complex of the amygdaloid nucleus (BLA). Infusions were either 10 min before training (Experiment 1) or 4 min after training (Experiment 2). In Experiment 1, the animals were tested three times: first for working memory (WM) 5 s after training, then for short-term memory (STM) 90 min later, and finally for long-term memory (LTM) 24 h later. Mecamylamine depressed and nicotine enhanced WM, STM, and LTM. In Experiment 2, the treatments were given after WM was presumably over. Again, mecamylamine inhibited and nicotine enhanced STM and LTM. The results indicate that nAChRs in BLA participate in the regulation of WM formation and STM and LTM acquisition and consolidation.     

The psychophysiological correlates of risk recognition among victims and non-victims of sexual assault

This study examined the psychophysiological correlates of risk recognition in sexual victimization. Victims and non-victims of sexual assault listened to a hypothetical date rape interaction and were asked to indicate the point at which the man had become sexually inappropriate. Subjective and objective (physiology) measures of responding as well as a measure of risk recognition in reaction to the date rape scenario were analyzed to evaluate both between and within-subjects' differences. Results showed that, relative to non-victims, victims of sexual assault displayed significant differences in risk recognition as well as both subjective and objective measures of physiological reactivity. Overall, the results indicate that altered physiological responding to relevant threat cues may be related to individuals' ability to identify and react to threatening sexual situations.     

Moderation and mediation effects of coping by Chinese American and European American adolescents

The authors asked 55 second-generation Chinese American adolescents (M age = 16.8 years) and 58 European American adolescents (M age = 17.0 years) to complete self-report measures of stress levels, use of coping strategies, psychological outcomes, and grades. Chinese American adolescents reported higher levels of everyday life event stress (e.g., stress from schoolwork), more depression, and higher grade point averages. Problem-focused and avoidance-coping behaviors moderated the effect of stress on negative adjustment for Chinese American youth but not for European American youth. Path analysis showed that avoidance coping behavior partially mediated the stress-to-negative adjustment relationship for Chinese American youth but not for European American youth. Stress was associated with lower grades in Chinese American youth, but the authors found no association for European American youth.     

Linguistic signatures of regulatory focus: how abstraction fits promotion more than prevention

In 3 experiments, the authors investigated how strategic inclinations associated with promotion versus prevention orientations--that is, eager approach versus vigilant avoidance, respectively--affect the use of language. It is hypothesized that eager promotion strategies used to attain desired end states entail using more abstract language than used with vigilant prevention strategies. This is shown to hold for experimentally induced relationship goals (Experiment 1) and communication goals (Experiment 2). In the 3rd experiment, the authors examined the impact of abstractly and concretely worded messages upon the behavioral intentions of chronically prevention- and promotion-oriented individuals and found support for the hypothesis that behavioral intentions to engage in specific activities are stronger when there is a fit between message wording and chronic orientation than when there is no fit. The broader implications of these findings are discussed.     

School-Based Intervention for Adolescents with Social Anxiety Disorder: Results of a Controlled Study

Social anxiety disorder, whose onset peaks in adolescence, is associated with significant impairment. Despite the availability of effective treatments, few affected youth receive services. Transporting interventions into schools may circumvent barriers to treatment. The efficacy of a school-based intervention for social anxiety disorder was examined in a randomized wait-list control trial of 35 adolescents (26 females). Independent evaluators, blind to treatment condition, evaluated participants at preintervention, postintervention, and 9 months later. Adolescents in the intervention group demonstrated significantly greater reductions than controls in social anxiety and avoidance, as well as significantly improved overall functioning. In addition, 67% of treated subjects, compared to 6% of wait-list participants, no longer met criteria for social phobia following treatment. Findings support the possible efficacy of school-based intervention for facilitating access to treatment for socially anxious adolescents.
