The status of mood-congruent free recall bias in anxious individuals was evaluated following incidental encoding of target words. Individuals with high and low levels of trait anxiety completed a modified Stroop task, which revealed an attentional bias for threat-related stimuli in anxious individuals. This group was significantly slower in naming the colour in which threat-related words were displayed compared to neutral words. In a subsequent free recall test for the words used in the modified Stroop task, anxious individuals recalled more threat-related words compared to low-anxious people. This difference was significant even when controlling for the false recall of items that had not been presented during study. These results support the view put forward by Russo, Fox, Bellinger, and Nguyen-Van-Tam (2001) that mood-congruent free recall bias in anxious individuals can be observed if the target material is encoded at a relatively shallow level. Moreover, contrary to Dowens and Calvo (2003), the current results show that the memory advantage for threat-related information in anxious individuals is not a consequence of response bias. 相似文献

Perceptual load theory (Lavie, 1995) states that participants cannot engage in focused attention when shown displays containing a low perceptual load, because attentional resources are not exhausted, whereas in high-load displays attention is always focused, because attentional resources are exhausted. An alternative "salience" hypothesis holds that the salience of distractors and not perceptual load per se determines selective attention. Three experiments were conducted to investigate the influence that target and distractor onsets and offsets have on selective processing in a standard interference task. Perceptual load theory predicts that, regardless of target or distractor presentation (onset or offset), interference from ignored distractors should occur in low-load displays only. In contrast, the salience hypothesis predicts that interference should occur when the distractor appears as an onset and would occur for distractor offsets only when the target was also an offset. Interference may even occur in highload displays if the distractor is more salient. The results supported the salience hypothesis. 相似文献

This study analyzed themes in documents written by 22 male accused spousal abusers to their female victims. Using Pence's Power and Equity model (1998), 86% of the themes denied equity and expressed power and control in the relation. Of these, 28% minimized or denied the abuse, 24% used the children to manipulate the victim, 16% showed disrespect for the victim, and 14% invoked male privilege (including God's ordination of the abusive relation). These hallmarks of tainted love are rooted in the desire of the accused abuser to maintain power and control over the victim. 相似文献

In the present research, we examined the influence of prime-target stimulus onset asynchrony (SOA) on Stroop-priming effects from masked words. Participants indicated the color of a central target, which was preceded by a 33-msec prime word followed either immediately or after a variable delay by a pattern mask. The prime word was incongruent or congruent with the target color on 75% and 25% of the trials, respectively. The words followed by an immediate mask produced reliable Stroop interference at SOAs of 300 and 400 msec but not at SOAs of 500 and 700 msec. The words followed by a delayed mask produced a reversed (i.e., facilitatory) Stroop effect, which reached significance at an SOA of 400 msec or longer, but never at the shorter 300-msec SOA. Such an differential time course of both types of Stroop priming effects provides further evidence for the existence of qualitative differences between conscious and nonconscious perceptual processes. 相似文献

A recent meta-analysis (P. Verhaeghen & L. De Meersman, 1998a) revealed that older adults show a reliable but significantly reduced negative priming effect compared with young adults. The present study provides an updated quantitative review on the effect of aging on the magnitude of the negative priming effect in identity tasks. This analysis demonstrated that the negative priming effect was not significantly different between young and old adults. This result differs from P. Verhaeghen and L. De Meersman's study. The implications of this finding for inhibitory-based theories of cognitive aging are discussed. 相似文献

Negative priming refers to the situation in which an ignored item on an initial prime trial suffers slowed responding when it becomes the target item on a subsequent probe trial. In this experiment (and a replication), we demonstrate two ways in which stimulus consistency (matching) governs negative priming. First, negative priming for identical words occurred only when the prime distractor changed color when it became the probe target (i.e., constant cue to read the red word); negative priming disappeared when the prime distractor retained its color as the probe target (i.e., cue switches from read the red prime word to read the white probe word). Second, negative priming occurred for identical words, but not for semantically related words, whether related categorically or associatively. This pattern of results is consistent with a memory retrieval account, but not with an inhibition account of negative priming, and casts doubt on whether there is semantic negative priming for words. 相似文献

Normal aging is associated with disruption of neural systems that subserve different aspects of cognitive function, particularly in the hippocampus and frontal cortex. Abnormalities in hippocampal function have been well investigated in rodent models of aging, but studies of frontal cortex function in aged rodents are few. We tested young (4–5 mo old) and aged (27–28 mo old) male Long-Evans rats on an attentional set-shifting task modified slightly from previous publication. After training on two problems in which the reward was consistently associated with the same stimulus dimension, and a reversal of one problem, a new problem was presented in which the reward was consistently associated with the previously irrelevant stimulus dimension (extradimensional shift [EDS]). Aged rats as a group were significantly impaired on the EDS, although some individual aged rats performed as well as young rats on this phase. In addition, some aged rats were impaired on the reversal, although a group effect did not reach significance in this phase. Impairment in neither reversal nor EDS was associated with impairments in spatial learning in the Morris water maze. Young rats with neurotoxic lesions of medial frontal cortex are also selectively impaired on the EDS. These results indicate that normal aging in rats is associated with impaired medial frontal cortex function. Furthermore, age-related declines in frontal cortex function are independent of those in hippocampal function. These results provide a possible basis for correlating age-related changes in neurobiological markers in frontal cortex with cognitive decline. 相似文献

The present study examined the influence of trait Agreeableness and its interaction with social role status on interpersonal correspondence as reflected in the within‐person relation between a person's communal (agreeable‐quarrelsome) behavior and perceptions of the interaction partner's communal behavior. We used a sample of working adults (original data set: 113 participants and 12,303 interpersonal events; constrained data set in the work setting: 109 participants and 3,193 interpersonal events) and an event‐contingent recording procedure to assess behavior in naturalistic interpersonal events. The results of multilevel modeling indicated that interpersonal correspondence was lower for high trait Agreeableness persons than for low trait Agreeableness persons, apparently due to less responsiveness to more disagreeable behavior by the other person in an interaction. High Agreeableness persons manifest greater interpersonal correspondence when in a high‐status role than when in a low‐status role, apparently by increasing responsiveness to disagreeable behavior from others. The results imply that high social role status may influence the effortful control process of high trait Agreeableness persons over their behavioral reactions to others' disagreeable behavior during interpersonal interactions. 相似文献

Prior research demonstrates that men generally experience higher levels of violent victimization relative to women. Using a high-risk sample of jail inmates, the present study draws on the core ideas from the self-control and societal norms toward the treatment of women literatures to examine the main and interactive effects of gender and self-control on violent victimization. Results indicate that gender and self-control both exhibit main effects on violent victimization net of control variables and that gender and self-control interact such that the gender gap in violent victimization disappears among men and women with low levels of self-control. We discuss the implications of our findings for theory, policy, and future research. 相似文献
