Young and older participants judged the veracity of young and older speakers' opinions about topical issues. All participants found it easier to judge when an older adult was lying relative to a young adult, and older adults were worse than young adults at telling when speakers were telling the truth versus lying. Neither young nor older adults were advantaged when judging a speaker from the same age group. Overall, older adults were more transparent as liars and were worse at detecting lies, with older adults' worse emotion recognition fully mediating the relation between age group and lie detection failures.  相似文献

As we envision constructive undertakings in the field of religion and science for the next decade, the emerging agenda of astrotheology is opening up a new theater for enquiry. Astrotheology provides a critical theological response to the field of astrobiology while critically assessing exciting new research on life in our solar system and the discovery of exoplanets. This article proposes four tasks for the astrotheologian: deliberate on (1) the scope of creation: is God's creation Earth‐centric or does it include the entire cosmos? (2) the question whether a single divine incarnation on Earth suffices for the cosmos or whether multiple incarnations—one for each inhabited planet—is required; (3) whether astrobiologists and other space scientists are sticking to their science or smuggling in ideology; and (4) readying terrestrial life for contact with extraterrestrial life by enumerating issues to be taken up by astroethics.  相似文献

The current study explores the association between emerging adult females’ experiences discussing relationships with their parents during adolescence and their current constraining relationship beliefs about mate selection. Constraining beliefs about the need for complete assurance of personal and relational success were more strongly held, whereas beliefs that cohabitation improves later marital outcomes, successful relationships require little effort, and opposites attract were less likely to be endorsed. A broad range of topics on romantic relationships were discussed, most often with mothers, during adolescence. What these young adults recalled discussing and how they felt about those discussions were associated with some, but not all, of their current constraining beliefs. Implications for future research are discussed.  相似文献

Unilateral entorhinal lesions have enjoyed immense popularity as a model of recovery from damage. In part, the popularity has been supported the laminar organization of the hippocampal formation, which allows for the dissection of the contribution of individual afferent pathways to the recovery process. The commissural/associational pathway is of particular interest, since electrophysiological and gross anatomical data, although limited, have correlated sprouting in this pathway with behavioral recovery. Unfortunately, information relating recovery to synaptic structure is lacking. Addressing this issue, two analyses were conducted. Initially, a quantitative review of the literature reporting behavioral recovery following this type of lesion was conducted using meta-analytic techniques. Using this detailed information across decades of research, multiple linear regression analysis was conducted to address whether the morphological correlates of recovery could predict behavioral recovery. This resulted in an equation relating morphology and recovery that stood up well to several diagnostic tests. Moreover, this model suggests that synapse structure (in particular, synapse size and curvature, as well as terminal compartmentalization and the density of multi-synaptic terminals) holds a greater potential to predict behavioral recovery than increases in synapse number, which is typically seen as the optimal anatomical measure of recovery. This initial attempt to identify, quantify, and validate a model of lesion recovery is an important initial step in understanding how synaptic morphology may help mediate recovery of function.  相似文献

Long-term memory is believed to depend on long-lasting changes in the strength of synaptic transmission known as synaptic plasticity. Understanding the molecular mechanisms of long-term synaptic plasticity is one of the principle goals of neuroscience. Among the most powerful tools being brought to bear on this question are genetically modified mice with changes in the expression or biological activity of genes thought to contribute to these processes. This article reviews how strains of mice with alterations in the cyclic adenosine monophosphate/protein kinase A/cyclic adenosine monophosphate-response element-binding protein signaling pathway have advanced our understanding of the biological basis of learning and memory.  相似文献

ABSTRACT

Risk assessments have become prevalent in the juvenile justice field. Many of these tools are adopted off-the-shelf and not adapted to fit the characteristics of a jurisdiction’s justice-involved youth. We examined the Positive Achievement Change Tool (PACT) in Iowa. Although used widely, the PACT is relatively unmodified. We updated the tool via item selection and weighting, gender-specific models and multiple outcomes, developing the Modified Positive Achievement Change Tool (M-PACT) for Iowa. We identified an average predictive accuracy increase of 7%. Evidence of reduced racial disparity was also observed, and research implications outline the need to customize assessments to improve predictive accuracy.  相似文献

Existing research on cyberbullying has primarily focused on adolescents in cross-sectional survey studies, with less research focusing on college students or employed adults over longer periods of time. To extend this literature, the current study examined new predictors and outcomes of cyberbullying perpetration (CP) and victimization (CV) among college students from two different universities that were followed across two time points. Risk factors were measured in line with previous theoretical models, including biological or personality-related variables (e.g., low self-control, dark-side personality traits, empathy) and environmental variables (e.g., perceived social support, lack of rule clarity, and internet use). Additionally, we examined several possible outcomes of CV and CP. Results from path analyses revealed that involvement with traditional bullying (either as a perpetrator or a victim) as well as Machiavellianism significantly predicted CV and CP. With regard to the cross-lagged associations between CV and CP, we found that Time 1 CV predicted time 2 CP, but Time 1 CP did not predict Time 2 CV. That is, being a victim of cyberbullying during the Fall semester predicted involvement as a perpetrator in the Spring semester. However, being a perpetrator during the Fall semester did not predict being a victim during the Spring semester. Regarding outcomes, we found that CV significantly predicted anxiety, depression, and helping behavior, and CP significantly predicted deviant behavior, but not GPA nor alcohol consumption. These findings have practical implications for college students as well as university student support services.  相似文献
