When target-defining features are specified in advance, attentional target selection in visual search is controlled by preparatory top-down task sets. We used ERP measures to study voluntary target selection in the absence of such feature-specific task sets, and to compare it to selection that is guided by advance knowledge about target features. Visual search arrays contained two different color singleton digits, and participants had to select one of these as target and report its parity. Target color was either known in advance (fixed color task) or had to be selected anew on each trial (free color-choice task). ERP correlates of spatially selective attentional target selection (N2pc) and working memory processing (SPCN) demonstrated rapid target selection and efficient exclusion of color singleton distractors from focal attention and working memory in the fixed color task. In the free color-choice task, spatially selective processing also emerged rapidly, but selection efficiency was reduced, with nontarget singleton digits capturing attention and gaining access to working memory. Results demonstrate the benefits of top-down task sets: Feature-specific advance preparation accelerates target selection, rapidly resolves attentional competition, and prevents irrelevant events from attracting attention and entering working memory. 相似文献

Participants saw a small number of objects in a visual display and performed a visual detection or visual-discrimination task in the context of task-irrelevant spoken distractors. In each experiment, a visual cue was presented 400 ms after the onset of a spoken word. In experiments 1 and 2, the cue was an isoluminant color change and participants generated an eye movement to the target object. In experiment 1, responses were slower when the spoken word referred to the distractor object than when it referred to the target object. In experiment 2, responses were slower when the spoken word referred to a distractor object than when it referred to an object not in the display. In experiment 3, the cue was a small shift in location of the target object and participants indicated the direction of the shift. Responses were slowest when the word referred to the distractor object, faster when the word did not have a referent, and fastest when the word referred to the target object. Taken together, the results demonstrate that referents of spoken words capture attention. 相似文献

Evaluative conditioning (EC) effects are often assumed to be based on a learned mental link between the CS (conditioned stimulus) and the US (unconditioned stimulus). We demonstrate that this link is not the only one that can underlie EC effects, but that if evaluative responses are actually given during the learning phase also a direct link between the CS and an evaluative response-a CS-ER link-can be learned and lead to EC effects. In Experiment 1, CSs were paired with USs and participants were asked to evaluate the pairs during the conditioning phase. Resulting EC effects were unaffected by a later revaluation of the USs, suggesting that these EC effects can be attributed to CS-ER learning rather than to CS-US learning. Experiment 2 replicated Experiment 1 with the difference that no evaluative responses were given during the learning phase. EC effects in this study were influenced by US revaluation, suggesting that these EC effects are mainly based on CS-US learning. In Experiment 3, it was shown that EC effects can be found even if the USs are entirely removed from the procedure and the CSs are only paired with enforced evaluative responses. Together the experiments show that the valence of a stimulus can change because of a contingency with an evaluative response. (PsycINFO Database Record (c) 2011 APA, all rights reserved). 相似文献

The current studies investigate the effects of homophobic labels on the self-perception of heterosexual males, hypothesizing that when exposed to homophobic epithets, they are motivated to underline their masculinity and claim a distinctly heterosexual identity by taking distance from homosexuals and, to a lesser degree, from women. Heterosexual male participants were subliminally (Study 1) and supraliminally (Study 2) primed either by a homophobic epithet or by a category label, and completed the Traditional Beliefs About Gender and Gender Identity scale. Participants stressed their heterosexual identity, but not their gender distinctiveness, when exposed to homophobic epithets, compared to category labels. Study 2 demonstrated that the relation between the homophobic label and the participants' heterosexual identity was mediated by how negatively they reacted to the antigay label. Heterosexual identity was enhanced in reaction to homophobic labels but not to an equally derogatory label referring to regional identity. Results are discussed within an intergroup framework. 相似文献

The role of attentional control in lexical ambiguity resolution was examined in two patients with damage to the left inferior frontal gyrus (LIFG) and one control patient with non-LIFG damage. Experiment 1 confirmed that the LIFG patients had attentional control deficits compared to normal controls while the non-LIFG patient was relatively unimpaired. Experiment 2 showed that all three patients did as well as normal controls in using biasing sentence context to resolve lexical ambiguities involving balanced ambiguous words, but only the LIFG patients took an abnormally long time on lexical ambiguities that resolved toward a subordinate meaning of biased ambiguous words. Taken together, the results suggest that attentional control plays an important role in the resolution of certain lexical ambiguities - those that induce strong interference from context-inappropriate meanings (i.e., dominant meanings of biased ambiguous words). 相似文献

This study examines 24‐months post‐baseline outcomes for thirty‐five Swedish antisocial youths who received either treatment in multidimensional treatment foster care (MTFC) or treatment as usual (TAU). MTFC is a community‐based treatment programme that has been successful in treating chronic juvenile offenders in the USA. This study is the first randomized control study outside the USA. The youth treated in the MTFC programme consistently showed some statistically significant positive treatment effects compared to the youth exposed to TAU. The results suggest that MTFC might be an effective method in treating youth with severe behaviour problems in a Swedish context. The authors conclude that the programme ought to be of great interest for Swedish social services as an alternative to traditional care. 相似文献

Across four studies, people sat (or reported they would sit) closer to physically similar others. Study 1 revealed significant aggregation in seating patterns on two easily observed characteristics: glasses wearing and sex. Study 2 replicated this finding with a wider variety of physical traits: race, sex, glasses wearing, hair length, and hair color. The overall tendency for people to sit beside physically similar others remained significant when controlling for sex and race, suggesting people aggregate on physical dimensions other than broad social categories. Study 3 conceptually replicated these results in a laboratory setting. The more physically similar participants were to a confederate, the closer they sat before an anticipated interaction when controlling for sex, race, and attractiveness similarity. In Study 4, overall physical similarity and glasses wearing similarity predicted self-reported seating distance. These effects were mediated by perceived attitudinal similarity. Liking and inferred acceptance also received support as mediators for glasses wearing similarity. 相似文献

Adaptive self-regulatory responses to negative events are associated with good mental health, social functioning, and physical
health. Two forms of emotion regulation that have received attention within the context of anger are cognitive reappraisal
and expressive suppression. Research suggests that greater heart rate variability (HRV) is a physiological indicator of adaptive
emotion regulation and decreased mental load. In the present experiment, we recorded HRV while 131 undergraduate women viewed
an anger-inducing video of a fellow student arguing for a position counter to that of the participant on an important political
issue. Immediately prior to viewing, participants were instructed to reappraise, suppress their emotions, or simply watch
the video as normal. Participants in the reappraisal condition showed increased HRV whereas those in the suppression and control
condition showed no such increase. These results provide support for increased HRV as a biological correlate of adaptive emotion
regulation. One implication is that cognitive reappraisal might afford greater autonomic flexibility when an individual is
confronted with anger-inducing events. 相似文献

The present study assessed preferential attentional processing of animal fear-relevant stimuli in two procedures, Search and
Interference tasks, which have been suggested to reflect on attentional capture due to the fear-relevance of the stimuli presented.
In the Search task, participants (N = 154) searched fear-relevant (i.e., snakes and spiders) and non fear-relevant (i.e.,
fish and birds) backgrounds to determine the presence or absence of a deviant animal from the opposite category. In the Interference
task, the same participants searched for the presence or absence of a neutral target (a cat) when either a snake, spider or
no distracter were embedded amongst backgrounds of other animal stimuli. Replicating previous findings, preferential attentional
processing of animal fear-relevant stimuli was evident in both procedures and participants who specifically feared one animal
but not the other showed enhanced preferential processing of their feared fear-relevant animal. However, across the entire
sample, there was no relationship between self-reported levels of animal fear and preferential processing which may reflect
on the fact that substantial preferential attentional processing of fear-relevant animals was evident in the entire sample.
Also, preferential attentional processing as assessed in the two tasks was not related. Delayed disengagement from fear-relevant
stimuli appeared to underlie performance in the search task but not in the interference task. 相似文献

Goal orientation theory is concerned with performance and learning goals in academic, athletic, and other ability areas. Here
we examine performance and learning goals for emotion regulation. We define performance goals for emotion regulation as seeking
to prove one’s ability to manage emotions; learning goals for emotion regulation are defined as seeking to improve one’s ability to manage emotions. In two studies, we tested the hypothesis that performance goals for emotion regulation
would be associated with greater use of defensive emotion regulation strategies and depressive symptoms. Results from both
studies showed that individuals with greater performance goals for emotion regulation reported higher levels of rumination
and thought suppression and greater depressive symptoms, while individuals with greater learning goals reported greater use
of cognitive reappraisal. The findings suggest that goals for emotion regulation may help explain individual differences in
use of defensive versus constructive emotion regulation strategies. 相似文献
