Future Expectations Among Adolescents: A Latent Class Analysis

Future expectations have been important predictors of adolescent development and behavior. Its measurement, however, has largely focused on single dimensions and misses potentially important components. This analysis investigates whether an empirically-driven, multidimensional approach to conceptualizing future expectations can substantively contribute to our understanding of adolescent risk behavior. We use data from the National Longitudinal Survey of Youth 1997 to derive subpopulations of adolescents based on their future expectations with latent class analysis. Multinomial regression then determines which covariates from Bronfenbrenner's ecological systems theory are associated with class membership. After modeling these covariates, we examine whether future expectations is associated with delinquency, substance use, and sexual experience. Our analysis suggests the emergence of four distinct classes labeled the Student Expectations, Student/Drinking Expectations, Victim Expectations, and Drinking/Arrest Expectations classes according to their indicator profiles. These classes differ with respect to covariates associated with membership; furthermore, they are all statistically and differentially associated with at least one adolescent risk behavior. This analysis demonstrates the additional benefit derived from using this multidimensional approach for studying future expectations. Further research is needed to investigate its stability and role in predicting adolescent risk behavior over time.     

Conflict Transformation, Stigma, and HIV-Preventive Structural Change

Over the prior decade, structural change efforts have become an important component of community-based HIV prevention initiatives. However, these efforts may not succeed when structural change initiatives encounter political resistance or invoke conflicting values, which may be likely when changes are intended to benefit a stigmatized population. The current study sought to examine the impact of target population stigma on the ability of 13 community coalitions to achieve structural change objectives. Results indicated that coalitions working on behalf of highly stigmatized populations had to abandon objectives more often than did coalitions working for less stigmatized populations because of external opposition to coalition objectives and resultant internal conflict over goals. Those coalitions that were most successful in meeting external challenges used opposition and conflict as transformative occasions by targeting conflicts directly and attempting to neutralize oppositional groups or turn them into strategic allies; less successful coalitions working on behalf of stigmatized groups struggled to determine an appropriate response to opposition. The role of conflict transformation as a success strategy for working on behalf of stigmatized groups is discussed.     

Nourishing or suppressing? The contradictory influences of perception of organizational politics on organizational citizenship behaviour

Drawing on both social exchange theory and impression management theory, this study sought to explain how perception of organizational politics (POP) influences organizational citizenship behaviour (OCB) through two contrary psychological processes. We proposed that through the mediation of job satisfaction, POP has an inhibiting effect on OCB; through the mediation of careerism, POP has a nourishing effect on OCB. Data were obtained from 393 police officers and their colleagues from a city police department in northern Taiwan. Results from structural equation modelling (SEM) revealed that the relationship between POP and OCB was negatively mediated by job satisfaction and positively mediated by careerism. Such antithetical psychological processes imply that employees may experience psychological dilemmas over the performance of OCB when they perceive their organization as political. Implications for theory and future research are discussed.

不同心理一致感初中生对压力的态度激活研究

该研究采用不同加工任务的间接测量方法,探讨不同心理一致感水平初中生对压力的外显认知倾向和内隐态度激活程度。结果表明:1)初中生较为稳定的积极认识和反应倾向在他们关于压力的外显认知加工中起了更为显著的作用;2)不同加工方式的虚惊率差异表明存在着初中生对压力情境的内隐态度,且这种无意识认知较为消极。     

负性情绪对压抑遗忘记忆的影响

该实验使用Think/No-think(T/NT)任务,从外显和内隐记忆两个方面探讨负性情绪、测试时间对压抑遗忘的影响。实验结果表明:在外显记忆成绩中情绪与T/NT任务的交互作用显著,在NT条件下中性词回忆的成绩优于负性词,同时,情绪的主效应显著,被试对中性词的记忆显著高于负性词。但是T/NT任务的主效应不显著,情绪×T/NT任务×测试时间的交互不显著。在内隐记忆成绩中,在所有条件下的记忆成绩均无显著性差异。     

Different types of exercise induce differential effects on neuronal adaptations and memory performance

Different exercise paradigms show differential effects on various forms of memory. We hypothesize that the differential effects of exercises on memory performance are caused by different neuroplasticity changes in relevant brain regions in response to different exercise trainings. We examined the effects of treadmill running (TR) and wheel running (WR) on the Pavlovian fear conditioning task that assesses learning and memory performance associated with the amygdala (cued conditioning) and both the amygdala and hippocampus (contextual conditioning). The skeletal muscle citrate synthase activity, an indicator of aerobic capacity, was elevated in rats received 4 w of TR, but not WR. While both TR and WR elevated the contextual conditional response, only TR facilitated the cued conditional response. Using a single-neuron labeling technique, we found that while both TR and MR enlarged the dendritic field and increased the spine density in hippocampal CA3 neurons, only TR showed these effects in basolateral amygdalar neurons. Moreover, both types of exercise upregulated synaptic proteins (i.e., TrkB and SNAP-25) in the hippocampus; however only TR showed similar effects in the amygdala. Injection of K252a, a TrkB kinase inhibitor, in the dorsal hippocampus or basolateral amygdala abolished the exercise-facilitated contextual or cued fear learning and memory performance, respectively, regardless of the types of exercise. In summary, our results supported that different types of exercise affect the performance of learning and memory via BDNF-TrkB signaling and neuroplasticity in specific brain regions. The brain region-specific neuronal adaptations are possibly induced by various levels of intensity/stress elicited by different types of exercise.     

Benefitting from a different perspective: The effect of a complementary matching of psychological distance and habitual perspective on emotion regulation

Psychological distance in terms of its purpose as a psychological adjustment is currently not well understood. Some researchers claim that psychological distance serves as an emotion regulator, while others argue that psychological distance has the reverse effect, leading to cognitive avoidance and rumination. To elucidate upon this discrepancy, we propose that a complementary matching of psychological distance to one's habitual psychological distance perspective may lead to better emotion regulation when compared to the original perspective (i.e. fixing on either psychological immersion or distance). This study hypothesizes that a complementary matching of psychological distance to one's habitual perspective generally leads to better emotion regulation; specifically, individuals with high avoidant attachment, who habitually distance themselves from their experiences, may benefit from psychological immersion, while individuals with high anxious attachment, who habitually immerse themselves in their experiences, may benefit from psychological distancing. A total of 83 participants completed measures of adult attachment orientations; read a conflict scenario, triggering their attachment systems; and then rewrote that scenario using designated pronouns, thereby employing psychological immersion or psychological distance. Participants in the self‐immersed condition were asked to write from the first‐person perspective, whereas those in the self‐distancing condition were asked to write from the third‐person perspective. The results support our hypothesis of a complementary matching of psychological distance and habitual perspective.
