According to Botvinick’s (2007) integrative account, conflict monitoring is aversive because individuals anticipate cognitive demand, whereas the revised reinforcement sensitivity theory (rRST) predicts that conflict processing is aversive because individuals anticipate aversive reinforcement of erroneous responses. Because these accounts give different reasons for the aversive aspects of conflict, we manipulated cognitive demand and the aversive reinforcement as a consequence of wrong choices in a go/no-go task. Thereby, we also aimed to investigate whether individual differences in conflict sensitivity (i.e., in trait anxiety, linked to high sensitivity of the behavioral inhibition system [trait-BIS]) represent the effects of aversive reinforcement and cognitive demand in conflict tasks. We expected that these manipulations would have effects on the frontal N2 component representing activity of the anterior cingulate cortex. Moreover, higher-trait-BIS individuals should be more sensitive than lower-trait-BIS individuals to aversive effects in conflict situations, resulting in a more negative frontal N2 for higher-trait-BIS individuals. In Study 1, with N = 104 students, and Study 2, with N = 47 students, aversive reinforcement was manipulated in three levels (within-subjects factor) and cognitive demand in two levels (between-subjects factor). The behavioral findings from the go/no-go task with noncounterbalanced reinforcement levels (Study 1) could be widely replicated in a task with counterbalanced reinforcement levels (Study 2). The frontal mean no-go N2 amplitude and the frontal no-go N2 dipole captured predicted reinforcement-related variations of conflict monitoring, indicating that the anticipation of aversive reinforcement induces variations in conflict monitoring intensity in frontal brain areas. The aversive nature of conflict was underlined by the more pronounced conflict monitoring in higher- than in lower-trait-BIS individuals.  相似文献

The present study sought to investigate genetic/biological attributions of obesity, their associations with a predisposition to obesity and their crossectional and longitudinal implications for weight regulation in obese individuals presenting for genetic testing and counselling. A total of 421 obese men and women underwent psychological and anthropometric assessment and a mutation screen of the melanocortin-4 receptor gene. At study entry, women revealed more genetic/biological attributions than men on the Revised Illness Perception Questionnaire adapted to obesity (86.2% versus 59.7%). Genetic/biological attributions of obesity were associated in both sexes with a family history of obesity, assessed through Stunkard's Figure Rating Scale. In both sexes, genetic/biological attributions were unrelated to weight regulation beliefs and behaviour (i.e. self-efficacy, controllability beliefs, restrained eating and physical activity), assessed through standardised questionnaires or interview at baseline and at six-month follow-up. In addition, causal attributions and weight regulation beliefs and behaviour were not predictive of body mass index at six-month follow-up. Overall, the results indicate that causal attributions of obesity to genetic/biological factors in obese individuals presenting for genetic screening and counselling are crossectionally and longitudinally unrelated to weight regulation and longer-term weight outcome. Those who attribute their obesity to genetic/biological factors likely have a familial obesity risk.  相似文献

Research on cognitive dissonance has fallen into several traditions. One, stimulated by Festinger and Carlsmith (1959), exposes subjects to experiences of induced compliance. A second, reflecting Brehm (1956), requires subjects to choose among alternative courses of action. It is argued that choice-among-alternatives experiments reflect only inconsistent preferences, whereas induced-compliance experiments involve normative elements, and that we should not expect these two traditions to generalize equally to all populations. Our hypotheses were tested with two subject populations: university undergraduates and older church members (the latter chosen for greater sensitivity to norms). Results confirmed that older church members were more likely to resolve dissonance when subjected to an induced-compliance design but indicated that the members were only minimally affected by a choice-among-alternatives design. Result are discussed for their theoretical and practical implications.  相似文献

Analysing the relationship between gender and memory, and examining the effects of age on the overall memory-related functioning, are the ongoing goals of psychological research. The present study examined gender and age group differences in episodic memory with respect to the type of task. In addition, these subgroup differences were also analysed in visual working memory. A sample of 366 women and 330 men, aged between 16 and 69 years of age, participated in the current study. Results indicate that women outperformed men on auditory memory tasks, whereas male adolescents and older male adults showed higher level performances on visual episodic and visual working memory measures. However, the size of gender-linked effects varied somewhat across age groups. Furthermore, results partly support a declining performance on episodic memory and visual working memory measures with increasing age. Although age-related losses in episodic memory could not be explained by a decreasing verbal and visuospatial ability with age, women's advantage in auditory episodic memory could be explained by their advantage in verbal ability. Men's higher level visual episodic memory performance was found to result from their advantage in visuospatial ability. Finally, possible methodological, biological, and cognitive explanations for the current findings are discussed.  相似文献

We propose a theoretical framework that explores the accumulation of work interruptions and their effects. Most research studies have dealt with interruptions as isolated phenomena, ignoring the simultaneous or sequential occurrence of interruptions common in everyday life. We fill this gap and provide insight into the process of the accumulation of interruptions by mapping deep-level regulation onto an observable sequence of actions. Furthermore, we explain how cumulative interruptions can lead to qualitatively different effects because of the interaction and joint development of isolated effects, identifying some mediating and moderating factors. In doing so, we disclose the relationships between the effects of single interruptions found in laboratory studies and the impacts on health and well-being of multiple interruptions found in applied research.  相似文献

Researchers assessed 58 preschoolers' reactions to an unfamiliar person and unfamiliar objects in their familiar home environment. Children participated in a 30-min procedure designed to elicit behavioral inhibition, including (a) a free-play period with a stranger present, (b) a structured interaction with the stranger, and (c) uncertainty-eliciting tasks. Behaviors representing the child's reactions toward the mother, stranger, and novel objects were coded. Mothers completed a temperament scale. Preschoolers exhibited behaviors indicative of inhibition toward unfamiliar social and nonsocial stimuli; behaviors remained stable across increasingly intrusive episodes. The approach/withdrawal component of temperament was related to behavioral inhibition. Individual differences in mood did not appear to be related to differences in inhibition. Parent reported temperament was related to researcher-observed behaviors.  相似文献

Measures of gender identity have almost exclusively relied on positive aspects of masculinity and femininity, although conceptually the self‐concept is not limited to positive attributes. A theoretical argument is made for considering negative attributes of gender identity, followed by five studies developing the Positive–Negative Sex‐Role Inventory (PN‐SRI) as a new measure of gender identity. Study 1 demonstrated that many of the attributes of a German version of the Bem Sex‐Role Inventory are no longer considered to differ in desirability for men and women. For the PN‐SRI, Study 2 elicited attributes characterizing men and women in today's society, for which ratings of typicality and desirability as well as self‐ratings by men and women were obtained in Study 3. Study 4 examined the reliability and factorial structure of the four subscales of positive and negative masculinity and femininity and demonstrated the construct and discriminant validity of the PN‐SRI by showing that the negative masculinity and femininity scales were unique predictors of select validation constructs. Study 5 showed that the new instrument explained variance in the validation constructs beyond earlier measures of gender identity. Key message: Even in the construction of negative aspects of gender identity, individuals prefer gender‐congruent attributes. Negative masculinity and femininity make a unique contribution to understanding gender‐related differences in psychological outcome variables. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

The Strengths and Difficulties Questionnaire (SDQ) is one of the most commonly used instruments for screening psychopathology in children and adolescents. This study evaluated the hypothesized five-factor structure of the SDQ and examined its convergent validity against comprehensive clinical diagnostic assessments. Data were derived from the National Comorbidity Survey - Adolescent Supplement (NCS-A), a nationally representative sample of U.S. adolescents aged 13 to 18 years. Parents/parent surrogates (n=6,483) was asked to complete a self-administered questionnaire including the SDQ and DSM-IV comprehensive diagnostic information on the participating adolescents. Confirmatory factor analysis (CFA) was conducted to assess the factor structure of the SDQ. The five-factor solution of the SDQ (including emotional, conduct, hyperactivity-inattention, peer relationship, and prosocial) provided a satisfactory fit to the data, and was invariant across sex, age, race/ethnicity and income subgroups. SDQ scores predicted a significantly increased probability of meeting criteria for a DSM-IV disorder, with better prediction for behavior disorders than for mood disorders. Decreasing the SDQ cutoffs to the 80th percentile significantly increased the sensitivity from 39% to 63% for the SDQ Total Difficulties Score, with an expected decrease in specificity from 93% to 87%. This work confirms the five-factor structure of the SDQ in an ethnically and sociodemogrpahically diverse community sample of adolescents. Our findings strengthen empirical evidence for the use of the parent-reported SDQ as a screening tool for DSM-IV behavioral and emotional disorders in adolescents identified in the general population.  相似文献
