This study investigated the possibility that enhanced memory for rejected distractor locations underlies the superior visual search skills exhibited by individuals with autism spectrum disorder (ASD). We compared the performance of 21 children with ASD and 21 age‐ and IQ‐matched typically developing (TD) children in a standard static search task and a dynamic search task, in which targets and distractors randomly changed locations every 500 ms, precluding the use of memory in search. Children with ASD exhibited overall faster reaction time (RT) relative to TD children, and showed no disruption in search efficiency in the dynamic condition, discounting the possibility that memory for rejected distractors augments their visual search abilities. Analyses of RT x set size functions showed no group differences in slopes but lower intercepts for the ASD group in both static and dynamic search, suggesting that the ASD advantage derived from non‐search processes, such as an enhanced ability to discriminate between targets and distractors at the locus of attention. Eye‐movement analyses revealed that the ASD and TD groups were similar in the number and spatial distribution of fixations across the search array, but that fixation duration was significantly shorter among children with ASD. Lower intercepts in static search were related to increased symptom severity in children with ASD. In summary, ASD search superiority did not derive from differences in the manner in which individuals with ASD deployed their attention while searching, but from anomalously enhanced perception of stimulus features, which was in turn positively associated with autism symptom severity. 相似文献

The authors tested the hypothesis that there is a correlation between hemispheric cognitive style and ear temperature. A sample of 100 participants completed a measure of hemispheric cognitive style, the Hemispheric Consensus Prediction Profile. Ear temperatures were taken in 2 sessions, 2 times for each ear at each session. Average left ear temperature was subtracted from average right ear temperature as an index of dominant temperature. Only 56 of the participants showed a stable dominant ear temperature. For these 56 participants, there was a statistically significant positive correlation between scores on the Hemispheric Consensus Prediction Profile and tympanic member temperature (Spearman's ρ =.29, 95% CI [.04,.51]). Individuals with a left hemispheric cognitive style tended to have a warmer left tympanic membrane temperature while those with a right hemispheric cognitive style tended to have a warmer right tympanic membrane temperature. Tympanic membrane temperatures are easily obtained using inexpensive and noninvasive technology. The relationship suggested by these findings may open new opportunities for the study of cerebral asymmetry. 相似文献

The tendency for emotions to be predictable over time, labelled emotional inertia, has been linked to low well-being and is thought to reflect impaired emotion regulation. However, almost no studies have examined how emotion regulation relates to emotional inertia. We examined the effects of cognitive reappraisal and expressive suppression on the inertia of behavioural, subjective and physiological measures of emotion. In Study 1 (N = 111), trait suppression was associated with higher inertia of negative behaviours. We replicated this finding experimentally in Study 2 (N = 186). Furthermore, in Study 2, instructed suppressors and reappraisers both showed higher inertia of positive behaviours, and reappraisers displayed higher inertia of heart rate. Neither suppression nor reappraisal were associated with the inertia of subjective feelings in either study. Thus, the effects of suppression and reappraisal on the temporal dynamics of emotions depend on the valence and emotional response component in question. 相似文献

According to the relevant alternatives theory of knowledge (RA), I know that p only if my evidence eliminates all relevant alternatives to p. Jonathan Schaffer has recently argued that David Lewis's version of RA, which is perhaps the most detailed version yet provided, cannot account for our failure to know in cases involving missed clues, that is, cases in which we see but fail to appreciate decisive evidence. I argue, however, that Lewis's version of RA survives exposure to missed clue cases. Moreover, even though Schaffer maintains that Lewis's Rule of Belief provides no protection against missed clue cases, I argue that we should credit the Rule of Belief with ensuring the survival of Lewis's version of RA. 相似文献

Using the materials and general procedure described by Rock and Gutman (1981), 160 subjects were required to attend selectively to a series of 10 red or green outlines of two overlapping contours. Immediately afterwards, six groups of 20 subjects were administered various kinds of recognition tests involving attended, unattended, or new figures, and two groups of 20 were asked to provide affect ratings of the test stimuli. Consistent with the findings of Rock and Gutman in 1981, attended outlines were selected as old more often than unattended or new ones. Although some data in a single-stimulus condition suggested that the unattended forms were "discriminated negatively," this effect was not replicated with forced-choice testing. Over-all, there was little evidence that, on unattended forms, subjects were significantly more accurate, differentially confident or displayed more liking than on new ones. These results are interpreted as supporting the view that attention is required for the cognitive representation of form. 相似文献

Two kinds of identity crisis 总被引:1,自引:0,他引:1
In order to outline a model of identity crisis, it is necessary to distinguish two types. In an identity deficit ("motivation crisis"), the individual experiences a lack of guiding commitments but struggles to establish personal goals and values. In an identity conflict ("legitimation crisis"), the person has several commitments which prescribe conflicting behavioral imperatives in some situations, such that at least one commitment may have to be betrayed. The literature on identity crisis is reviewed in connection with this distinction, and an attempt is made to delineate the causes, the subjective experiences, behavioral consequences, and modes of resolution of each type of crisis. 相似文献

Expectancies of reinforcer location and quality as cues for a conditional discrimination in pigeons 总被引:1,自引:0,他引:1

Experiment 1 demonstrated that reliably correlating different reinforcer locations (top vs. bottom) with sample stimuli markedly enhanced the performance of White Carneaux pigeons in a spatial conditional discrimination. This differential outcome effect was more evident at longer retention intervals. In Experiment 2, pigeons were given the opportunity to learn about two redundant reinforcer features--location (top vs. bottom) and quality (grain vs. chow). Which reinforcer feature exerted control over choosing depended on task structure. In the congruent task, where pecks to the top key operated the top feeder and pecks to the bottom key operated the bottom feeder, reinforcer location exerted predominant control. In the incongruent task, where pecks to the top key operated the bottom feeder and vice versa, reinforcer quality exerted exclusive control. These results have implications for the nature of reinforcer representations in instrumental learning. 相似文献

Writing programs for the student psychology laboratory on the Apple II series of microcomputers presents the programmer with a number of problems. Among these are increasing program execution speed, obtaining precise response and interval timing, reducing program memory requirements, obtaining efficient disk I/O, providing good error trapping, and presenting clear screen displays. Since Applesoft BASIC is not equipped with many of the desirable features of a more advanced language, ways to solve these problems are not obvious. This paper suggests a number of potential solutions and provides additional sources of information. 相似文献
