It is widely argued that people with autism have difficulty processing ambiguous linguistic information in context. To investigate this claim, we recorded the eye-movements of 24 adolescents with autism spectrum disorder and 24 language-matched peers as they monitored spoken sentences for words corresponding to objects on a computer display. Following a target word, participants looked more at a competitor object sharing the same onset than at phonologically unrelated objects. This effect was, however, mediated by the sentence context such that participants looked less at the phonological competitor if it was semantically incongruous with the preceding verb. Contrary to predictions, the two groups evidenced similar effects of context on eye-movements. Instead, across both groups, the effect of sentence context was reduced in individuals with relatively poor language skills. Implications for the weak central coherence account of autism are discussed. 相似文献

ABSTRACT We tested a theoretical model of personality structures underlying patterns of intra-individual variability in contextualized appraisals. The KAPA (Knowledge-and-Appraisal Personality Architecture) model was tested experimentally among smokers appraising their efficacy to resist the urge to smoke in high-risk situations. In a novel design, we assessed self-knowledge and situational beliefs idiographically and employed cognitive priming to manipulate the accessibility of self-knowledge experimentally. The results confirmed the unique KAPA-model prediction that priming would affect appraisals in a contextualized manner. Priming positively valenced self-knowledge enhanced self-efficacy appraisals specifically within that subset of situations that were relevant to the primed knowledge. The results were consistent with the hypothesis that systems of self- and situational knowledge underlie consistency and variability in appraisals. 相似文献

Many animal species use reaching for food to place in the mouth (reach-to-eat) with a hand, and it may be a primitive movement. Although researchers (I. Q. Whishaw, 2005; A. N. Iwaniuk & I. Q. Whishaw, 2000; M. Gentiluci, I. Toni, S. Chieffi, & G. Pavesi, 1994) have described visual guidance of reaching in both normal and brain-injured human and nonhuman primates, researchers have not described the contribution of vision during advance of the limb to grasp food and during withdrawal of the limb with food to the mouth. To evaluate visual contributions, the authors monitored eye movements in young adults as they reached for food with and without vision. Participants visually engaged the target prior to the 1st hand movement and disengaged it as the food was grasped. Visual occlusion slowed limb advance and altered digit shaping but did not affect withdrawal. The dependence on visual control of advance but not withdrawal suggests that the reach-to-eat movement is a composite of 2 basic movements under visual and tactile/proprioceptive guidance, respectively. 相似文献

Event counting provides a laboratory paradigm for studying types and causes of error in routine activity. Experiment 1 demonstrated that as more time per event is allowed, counting errors typically are undercounts, then overcounts as the time per event is extended to approximately 3 s. Experiments 2 and 3 examined 2 possible causes of this phenomenon, forgetting and confusions due to overrehearsal of the next number to be used. These findings demonstrate that overcount errors during event counting are reduced by working memory loads, which may result from a lower ability to rehearse the current total. Implications for theoretical accounts of goal representation, control, and error monitoring are discussed. 相似文献

We examined the relationship between subordinates’ family to work balance (conflict and enrichment) and two dimensions of contextual performance (interpersonal facilitation and job dedication) reported by supervisors. Beyond the direct effects, we hypothesized that supervisor’s appraisals of employee conflict and enrichment would influence the supervisor’s contextual performance ratings. Data collected from a matched sample of 156 private sector employees and their supervisors indicated that the supervisor’s performance ratings were impacted by the supervisor’s appraisal of enrichment. However, the supervisor’s appraisal of conflict only mattered for interpersonal facilitation. There was a direct effect of subordinate’s conflict on both dimensions of contextual performance. 相似文献

Dot probe studies indicate that masked fearful faces modulate spatial attention. However, without a baseline to compare congruent and incongruent reaction times, it is unclear which aspect(s) of attention (orienting or disengagement) is affected. Additionally, backward masking studies commonly use a neutral face as the mask stimulus. This method results in greater perceptual inconsistencies for fearful as opposed to neutral faces. Therefore, it is currently unclear whether the effects of backward masked fearful faces are due to the fearful nature of the face or perceptual inconsistencies. Equally unclear, is whether this spatial attention effect is due to orienting or disengagement. Two modified dot probe experiments with neutral (closed mouth in Experiment 1) and smiling (open mouth in Experiment 2) masks were used to determine the role of perceptual inconsistencies in mediating the spatial attention effects elicited by masked fearful faces. The results indicate that masked fearful faces modulate the orienting of spatial attention, and it appears that this effect is due to the fearful nature of the face rather than perceptual inconsistencies between the initial faces and masks. 相似文献

Research in psychology has reported that, among the variety of possibilities for assessment methodologies, summary evaluation offers a particularly adequate context for inferring text comprehension and topic understanding. However, grades obtained in this methodology are hard to quantify objectively. Therefore, we carried out an empirical study to analyze the decisions underlying human summary-grading behavior. The task consisted of expert evaluation of summaries produced in critically relevant contexts of summarization development, and the resulting data were modeled by means of Bayesian networks using an application called Elvira, which allows for graphically observing the predictive power (if any) of the resultant variables. Thus, in this article, we analyzed summary-evaluation decision making in a computational framework. 相似文献
