Plaisted, O'Riordan and colleagues (Plaisted, O'Riordan & Baron-Cohen, 1998; O'Riordan, 2004) showed that school-age children and adults with Autism Spectrum Disorder (ASD) are faster at finding targets in certain types of visual search tasks than typical controls. Currently though, there is very little known about the visual search skills of very young children (1-3-year-olds) - either typically developing or with ASD. We used an eye-tracker to measure looking behavior, providing fine-grained measures of visual search in 2.5-year-old toddlers with and without ASD (this representing the age by which many children may first receive a diagnosis of ASD). Importantly, our paradigm required no verbal instructions or feedback, making the task appropriate for toddlers who are pre- or nonverbal. We found that toddlers with ASD were more successful at finding the target than typically developing, age-matched controls. Further, our paradigm allowed us to estimate the number of items scrutinized per trial, revealing that for large set size conjunctive search, toddlers with ASD scrutinized as many as twice the number of items as typically developing toddlers, in the same amount of time. 相似文献

The extent to which individuals are seen as fulfilling their social roles is related to the extent they are seen as successful in that role. Using social role theory, the congruence of job roles and gender roles was examined among labor mediators, a profession requiring both agentic and communal characteristics. A total of 362 employees and employers involved in a workplace dispute that went to governmental mediation were recruited in Quebec, Canada. Regression analyses assessed how impartiality and empathy contributed to parties’ trust in their mediators for male and female mediators. Comparisons of regression structures suggest that perceptions of gender incongruent job characteristics were better predictors of trust in the mediator than gender congruent characteristics. Theoretical and applied implications are discussed. 相似文献

There are two kinds of afterimages. In negative afterimages, looking at a blank field after staring at a colored figure gives a figure whose color is complementary to that of the original figure. Less well understood and studied is the phenomenon of induced positive afterimages, in which staring at a colored area surrounding a small white test patch produces an afterimage in which the hue of the surround is transferred into the previously white area. Using these differences between positive and negative afterimages and also simultaneous color contrast, which has an effect on a test patch different from either of the afterimage effects, we describe a new effect, metameric intransitivity, in which perceptually similar images can generate markedly different afterimages, whereas perceptually different images can generate indistinguishable afterimages. Supplemental figures depicting the stimuli, results, and method for generating the intransitive metamers in this study may be downloaded from http://app.psychonomic-journals.org/content/supplemental. 相似文献

Over seven decades ago Gestalt psychologist Kurt Koffka described a remarkable effect: when a contiguous gray ring is placed on a background half of one shade of gray, half of another, the ring appears homogeneous. However, if the ring is slightly divided, the two halves of the ring appear different shades of gray, the half of the ring on the darker background appearing lighter than the half of the ring on the lighter background. The Gestalt principle of continuity is used to explain this effect. We show that when the ring is made thinner it appears heterogeneous even when contiguous. We also illustrate this in the additional material with a colored background with more than two regions. 相似文献

Voices, in addition to faces, enable person identification. Voice recognition has been shown to evoke a distributed network of brain regions that includes, in addition to the superior temporal sulcus (STS), the anterior temporal pole, fusiform face area (FFA), and posterior cingulate gyrus (pCG). Here we report an individual (MS) with acquired prosopagnosia who, despite bilateral damage to much of this network, demonstrates the ability to distinguish voices of several well‐known acquaintances from voices of people that he has never heard before. Functional magnetic resonance imaging (fMRI) revealed that, relative to speech‐modulated noise, voices rated as familiar and unfamiliar by MS elicited enhanced haemodynamic activity in the left angular gyrus, left posterior STS, and posterior midline brain regions, including the retrosplenial cortex and the dorsal pCG. More interestingly, relative to noise and unfamiliar voices, the familiar voices elicited greater haemodynamic activity in the left angular gyrus and medial parietal regions including the dorsal pCG and precuneus. The findings are consistent with theories implicating the pCG in recognizing people who are personally familiar, and furthermore suggest that the pCG region of the voice identification network is able to make functional contributions to voice recognition even though other areas of the network, namely the anterior temporal poles, FFA, and the right parietal lobe, may be compromised. 相似文献

All psychologists must uphold the same ethical standards about confidentiality even though each state imposes different legal limits on their ability to protect clients' confidences. The resulting ethical-legal confusion is exacerbated by legally based confidentiality training that treats legal exceptions as if they were the rule and fosters the impression that attorneys are now the only real experts about this aspect of practice. This article provides an ethics-based confidentiality practice model that clarifies the ethical rule and puts its legal exceptions into ethical perspective. Like the Confidentiality section of the American Psychological Association's (2002) Ethical Principles of Psychologists and Code of Conduct, this outline would apply to all psychologists regardless of state laws, but the details of its implementation would vary according to role and setting. It can be used as a universal training outline, a consultation and supervision tool, a guide to professional practice, and a basis for clearer ongoing conversation about the ethics of "conditional confidentiality." Psychologists can use this practice model to regain their status as experts about the confidentiality ethics of their own profession. 相似文献

Participants were trained and tested to select stimuli of differing physical quantities in the presence of 2 color contextual cues for more than and less than. Following more than and less than relational training, participants allocated the majority of their responses to the slot machine that shared formal properties of color with the contextual cue for more than, despite the identical payout probabilities of the slot machines. 相似文献

Marital conflict is related to well-being in children and adults (E. M. Cummings & P. T. Davies, 2002). Marital conflict is likely most effectively ameliorated before it becomes clinically significant. However, families without significant problems may be unwilling to participate in couples therapies or other lengthy or intensive interventions. Responding to this gap, the authors developed a 4-session psychoeducational program about marital conflict for community families. Couples with children 4-8 years of age were randomly blocked into 1 of 3 groups: (1) a parent-only group (n = 24), (2) a parent-child group (n = 33), or (3) a self-study group (n = 33). Pre- and posttest and 6-month and 1-year assessments were conducted. This report evaluates (a) whether participation in a psychoeducational program for parents improved marital conflict, especially concerning ways of expressing disagreements, and (b) whether changes in marital conflict subsequently improved marital satisfaction, parenting, and child adjustment. Greater constructive and less destructive marital conflict was observed at all assessments for treatment groups, and these changes were linked with improvements in other family processes. The findings support the promise of brief, psychoeducational programs for improving marital conflict for community samples. 相似文献

Expressed emotion (EE), an index of family member criticism and emotional overinvolvement, predicts outcome among adults and children with mental disorders. However, limited research exists on factors contributing to EE. Aims of the current study were to (a) examine EE in mothers of young children; (b) assess relationships between demographic factors and EE in a diverse sample; and (c) investigate whether family stress and functioning, including quality of marital relationship, life events, maternal stress, and family environment, predict EE. In the current study, 276 mothers completed questionnaires when their children were between 1 and 3 years of age and a measure of EE when their children were in kindergarten. Results indicated that family expressiveness was the most consistent predictor of EE. Further research seems warranted to better delineate associations between family functioning and EE. 相似文献
