Selective attention and emotional vulnerability: assessing the causal basis of their association through the experimental manipulation of attentional bias 总被引:11,自引:0,他引:11

Although it is well-established that vulnerability to negative emotion is associated with attentional bias toward aversive information, the causal basis of this association remains undetermined. Two studies addressed this issue by experimentally inducing differential attentional responses to emotional stimuli using a modified dot probe task, and then examining the impact of such attentional manipulation on subsequent emotional vulnerability. The results supported the hypothesis that the induction of attentional bias should serve to modify emotional vulnerability, as revealed by participants' emotional reactions to a final standardized stress task. These findings provide a sound empirical basis for the previously speculative proposal that attentional bias can causally mediate emotional vulnerability, and they suggest the possibility that cognitive-experimental procedures designed to modify selective information processing may have potential therapeutic value. 相似文献

Linguists draw a distinction between two types of interrogatives: discourse linked (d-linked) phrases such as which man, which implies the existence of a set of contextually determined entities (men) from which the speaker is asking for a choice, and non–d-linked interrogatives such as who, which carry no such implication. Two questionnaires and an on-line reading study showed that readers prefer a d-linked phrase more than a non–d-linked phrase as the antecedent for a pronoun, suggesting that d-linked phrases are immediately instantiated in a discourse representation that is checked during the process of pronoun interpretation. Comparable difficulty is not observed for non–d-linked interrogatives. A questionnaire and an on-line listening study also showed that readers and listeners were more willing to accept a grammatical island violation containing a pronoun when the pronoun's antecendent was a d-linked interrogative than when the antecedent was non–d-linked, suggesting that they check a discourse representation for the pronoun antecedent. All results suggest that d-linked phrases are immediately interpreted in a discourse representation, not just in a syntactic representation. 相似文献

This study investigated the effects of pediatric traumatic brain injury (TBI) on prospective memory. Fourteen children and 14 adolescents with TBI were compared with 25 and 23 noninjured children and adolescents, respectively. Based on a prefrontal model, the cognitive demand on the ongoing component of a prospective-memory task was manipulated. Overall, those with TBI had poorer prospective-memory performance than their noninjured peers. Performance was worse in a high cognitive-demand condition than a low, and younger children performed worse than adolescents. Decreases in performance from the low- to high-demand conditions were not significantly different between the two children's groups but were between the two adolescents' groups. Furthermore, the age and injury effects were reflected in the performances on executive function tests: the Self-ordered Pointing Task (SOPT), and the Stroop Color Word Interference Test. The Tower of London (TOL), which did not produce age or injury effects, was nevertheless found to be an important predictor of performance on the high-demand task in those with TBI. Although previous research has demonstrated impaired prospective memory performance in children with TBI, this study attempted to explain why this might occur, specifically that the prefrontal regions might be implicated. 相似文献

Recent work has identified Behavioral Approach System (BAS) sensitivity as a risk factor for the first onset and recurrence of mood episodes in bipolar disorder, but little work has evaluated risk factors for the prospective development of hypomanic symptoms in individuals at risk for, but without a history of, bipolar disorder. The present study used a prospective behavioral high-risk design to evaluate the impact of positive overgeneralization, a cognitive correlate of risk for hypomania, on hypomanic symptoms in individuals with high vs. moderate BAS sensitivity, but without a history of mood elevation. Hierarchical linear regressions indicated that upward positive overgeneralization and BAS sensitivity interacted to predict increased levels of hypomanic symptoms at follow-up, controlling for initial hypomanic symptoms. The pattern of this interaction was such that positive overgeneralization predicted higher levels of hypomanic symptoms among high-BAS, but not moderate-BAS, individuals. Thus, the self-reported tendency to experience grandiose increases in confidence following success may confer additional risk for mood elevation among individuals already at risk for developing bipolar disorder. Potential implications for prevention and treatment are discussed. 相似文献

In extending the etiological chain of the hopelessness theory of depression (Abramson, Metalsky, & Alloy, 1989), Rose and Abramson (1992) proposed a developmental model by which childhood maltreatment may contribute to the development of a negative inferential style. Once developed, this negative inferential style leaves the individual vulnerable to developing hopelessness and symptoms of hopelessness depression. In the current cross‐sectional study, reports of childhood emotional, but not physical or sexual, maltreatment were significantly related to undergraduates' inferential styles. In addition, results from path analyses indicated that inferences about specific experiences of childhood emotional maltreatment mediated this relationship. Testing Rose and Abramson's entire model, results from path analyses supported a partial, but not full, mediation model. 相似文献

This article integrates research on minority influence and information sampling in groups. The traditional information‐sampling paradigm implies that the discussion bias for common over unique information affects all types of groups universally. We proposed an alternative in which information sampling depends on the composition of opinions. We proposed that groups with a minority opinion may focus more on unique information and that a minority opinion may lead majority members to consider more preference‐inconsistent information. In a study that tested how minority, majority, and unanimous group members differ in their discussion of information, results lent no support for the alternative conception of information sampling. However, when the minority prevailed, minority members repeated significantly more common information than when the majority prevailed. 相似文献

Although studies have suggested that reports of childhood maltreatment are related to depressive cognitions and symptom levels in adults, it is unclear whether the significant relations reported are due to the recall of specific maltreatment experiences, how individuals globally label their experiences (i.e., whether they believe they were maltreated during childhood), or both. Results from the current study supported the moderating role of global beliefs only for childhood sexual maltreatment. Specifically, the relationship between reports of specific childhood sexual maltreatment experiences and both dysfunctional attitudes and depressive symptom levels was significant only among participants who also globally endorsed a history of childhood sexual maltreatment. In contrast, the correlates of specific childhood emotional and physical maltreatment experiences were, for the most part, independent of whether the participants globally endorsed childhood emotional or physical maltreatment, respectively. 相似文献
