The effects of age on the ability to resolve perceptual ambiguity are unknown, though it depends on frontoparietal attentional networks known to change with age. We presented the bistable Necker cube to 24 middle-aged and OAs (older adults; 56–78 years) and 20 YAs (younger adults; 18–24 years) under passive-viewing and volitional control conditions: Hold one cube percept and Switch between cube percepts. During passive viewing, OAs had longer dominance durations (time spent on each percept) than YAs. In the Hold condition, OAs were less able than YAs to increase dominance durations. In the Switch condition, OAs and YAs did not differ in performance. Dominance durations in either condition correlated with performance on tests of executive function mediated by the frontal lobes. Eye movements (fixation deviations) did not differ between groups. These results suggest that OAs’ reduced ability to hold a percept may arise from reduced selective attention. The lack of correlation of performance between Hold and executive-function measures suggests at least a partial segregation of underlying mechanisms. 相似文献

Using the German Socio-Economic Panel, we analyze the relevance of modeling social comparisons to determine their effect on subjective well-being. We find that it is important to model social comparisons in such a way that captures the sensitivity of individuals to proximity. The impact on subjective well-being differs depending on the manner in which proximity is modeled, revealing that the underlying processes in comparisons are not homogenous along the income distribution. Additionally, our results point out that social and cultural capital modify the effect of social comparisons and such modification depends on the sensitivity to proximity. 相似文献

The present study sought to investigate how alexithymia (a deficit in identifying and describing emotions) may hinder the development of posttraumatic growth (PTG) and contribute to ongoing distress. Participants were 250 undergraduate college students who had experienced a highly stressful event in the past six months. Regression analyses were conducted to examine how alexithymia contributes to PTG and distress in addition to other known predictors. Analyses revealed that alexithymia was a significant negative predictor of PTG, and a significant positive predictor of distress. It was also found that Difficulty in Identifying Feelings was the alexithymia component that best predicted PTG and distress. 相似文献

Ethical climate in organisations has been studied widely and its influence on ethical behaviour has been documented. However, little is known about the ethical climate at university context and about its antecedents. Universities are social change institutions and their ethical climate could influence the ethical behaviour of future economic, social and political leaders. The current study analyses the perceived ethical climate in Business Studies Higher Education Institutions in Spain and whether university’s ownership, size and signing up for international initiatives influence it. The study is based on survey responses of 385 lecturers of Spanish Business Studies Faculties to an ethical climate questionnaire and on survey responses of 33 Business Studies Deans to a questionnaire related to the commitment to ethics and social responsibility in each Faculty. An exploratory factor analysis has been used as well as ANOVA tests and lineal regressions. The results reveal the predominance of an instrumental ethical climate in Spanish Business Faculties, an ethical climate that does not promote ethical behaviour or organisational commitment among its members. The results also confirm the significant influence of university’s ownership and signing up for Principles for Responsible Management Education on the ethical climate in Business Higher Education institutions. This study advances the understanding of the ethical climate in Business Studies institutions, and suggests measures to be taken by university managers in order to improve ethical judgment and behaviour of the university community. 相似文献

“To‐be‐forgotten” statements become less true: Memory processes involved in selection and forgetting lead to truthfulness changes of ambiguous sentences 下载免费PDF全文
Ana Sofia Santos Tânia Ramos Leonel Garcia‐Marques Paula Carneiro 《Scandinavian journal of psychology》2017,58(3):205-210
What happens when people try to forget something? What are the consequences of instructing people to intentionally forget a sentence? Recent studies employing the item‐method directed forgetting paradigm have shown that to‐be‐forgotten (TBF) items are, in a subsequent task, emotionally devaluated relative to to‐be‐remembered (TBR) items, an aftereffect of memory selection (Vivas, Marful, Panagiotidou & Bajo, 2016). As such, distractor devaluation by attentional selection generalizes to memory selection. In this study, we use the item‐method directed forgetting paradigm to test the effects of memory selection and inhibition on truth judgments of ambiguous sentences. We expected the relative standing of an item in the task (i.e., whether it was instructed to be remembered or forgotten) to affect the truthfulness value of that item, making TBF items less valid/truthful than TBR items. As predicted, ambiguous sentences associated with a “Forget” cue were subsequently judged as less true than sentences associated with a “Remember” cue, suggesting that instructions to intentionally forget a statement can produce changes in the validity/truthfulness of that statement. To our knowledge, this is the first study to show an influence of memory processes involved in selection and forgetting on the perceived truthfulness of sentences. 相似文献

How Does Explicit Versus Implicit Risk Information Influence Adolescent Risk‐Taking Engagement? 下载免费PDF全文

Adolescents have been shown to be more likely to engage in risky behaviors in daily life. Many studies have indicated that adolescents could make advantageous choices when they receive explicit information but could fail to choose advantageously when they are not informed about risks. The current study aimed to examine the influence of explicit risk information (i.e., when risk information is directly available) versus implicit risk information (i.e., when risk information has to be learned from feedback) on risk‐taking engagement, in order to clarify whether the enhanced risk‐taking observed in decision making under ambiguity in adolescents results from either a greater exploration of ambiguous situations (i.e., a higher ambiguity tolerance) or a specific difficulty associated with learning based on previous choices' outcomes. Adolescents and young adults completed a new adaptation of the Balloon Analogue Risk Task. They were required to accumulate as many points as possible by inflating balloons associated with variable break points and avoiding explosions. This adaptation involved a manipulation of the information level with two conditions, an “informed” condition and a “noninformed” condition, in which the participants had to learn the matching of colors with balloons' resistances based on feedback. The results demonstrated that providing explicit risk information allows adolescents to be as efficient as adults at the end of the game. In contrast, adolescents failed to adjust risk‐taking to the balloon resistance in the noninformed condition. These findings critically suggest that this failure reflects a specific impairment of feedback‐based learning ability but not a global excess of risk‐taking during adolescence.

Several studies have documented the high prevalence of psychopathology and behavior problems in Williams syndrome (WS). However, the links between cognitive development and such symptoms need further clarification. Our study aims to expand current knowledge on levels of behavior problems and its links to cognition in a sample of Brazilian individuals with WS. A total of 25 children and adolescents with WS and their parents participated in this study. The participants’ IQs were assessed with the Wechsler Scales of Intelligence (for children or adults) and parental reports of psychopathology/behavior problems were collected using the Child Behavior Checklist (CBCL). The presence of clinically significant attention problems was a main feature in our sample of children and adolescents with WS. In the children, higher IQ scores were found to be significantly associated with less externalizing problems, while in the adolescents cognitive abilities were found to be associated with less internalizing symptoms. These results provide further insight into the links between psychopathology and behavior problems and cognitive abilities in WS, and suggest the need to take age into consideration when analyzing such relationships. 相似文献

Dual‐system models propose that cognitive processing can occur either intuitively or deliberately. Unlike deliberate decision strategies, intuitive ones are assumed to have an emotional component attached to the decision process. We tested if intuitive decisions are indeed accompanied by an emotional response while deliberate decisions are not. Specifically, we conducted a psychophysiological study in which participants were instructed to decide either intuitively or deliberately if three simultaneously presented words were semantically coherent or incoherent (triad task). The degree of emotionality of these two decision strategies (intuitive vs. deliberate) was compared using changes in electrodermal activity (EDA) and the reaction time (RT) effect of an affective priming paradigm as primary measurements. Based on a valence‐arousal model, our results revealed that intuitive and deliberate judgments do not differ as to their emotional valence but that they do differ in emotional arousal. Most notably, sympathetic activation during intuitive judgments was significantly lower compared to sympathetic activation during deliberate judgments. Our results reflect that a relaxed state of mind—manifested in low sympathetic activity—could underlie the holistic processing that is assumed to facilitate the proliferation of semantic associations during coherence judgments. This suggests that coherence judgments made under an (instructed) intuitive decision mode have a specific psychophysiological signature and that arousal is the differentiating component between intuitive and deliberate decision strategies. © 2016 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd. 相似文献
