In two experiments preschool children chose one of two test forms that looked like previously exposed distortions of a letterlike-form. In Exp. I a distance metric was defined to measure the physical discrepancy between forms. It was found that the distance relationship between distortions and particular test forms did not designate the children's choice behavior. In Exp. II the children were able to choose previously exposed distortions when particular test forms contained novel features. The results are related to distinctive feature and prototype hypotheses to account for children's performance in recognizing forms. 相似文献

The purpose of this study was to investigate obedience to an E’s commands as a function of E competency. Based upon Orne’s (1962, 1969) discussion of the demand characteristics inherent in the typical aggression study, it was hypothesized that E incompetence would decrease S obedience. Competence was manipulated by: (1) presenting some Ss with a nervous and inexperienced E, and (2)“accidentally” killing the victim (a rat) midway through the experiment. Thirty-two undergraduate female Ss participated in the experiment—supposedly a study on the physiological effects of stress. Obedi6nce was operationalized as the difference, in simple reaction time, between trials on which Ss were told that their response might result in shock to the rat and trials on which they were told that their response might save the rat from shock. Significant differences in obedience were obtained between competent and incompetent E conditions, and a significant “kill” effect was found in the competent E conditidn. The results of this study suggested that the extreme acts of obedience observed in the laboratory (e.g., Milgram, 1963) occur only when E is perceived as competent. This finding imposes limits on the generalizability of laboratory studies of obedience. 相似文献

The effects of the relationship between the presentation of a verbal stimulus (“right”) and an established reinforcer (M&Ms) on the reinforcement efficacy of the verbal stimulus was tested with three groups of retarded boys. Blocks of training and test trials alternated. During training of the Discriminative Group, “right” reliably preceded candy. For the Contiguous Group, “right” accompanied candy, and for the Random Group “right” and candy were programmed independently. “Right” promoted learning in the Discriminative Group but did not in the latter two groups. The results support Cairns' analysis of the often found failure of approval to be an effective reinforcer in laboratory tasks. 相似文献

Research on young people's aspirations and their capacity to aspire to higher education has proliferated in recent decades, however, very little attention has been paid to the creative arts. Diversity in the arts remains a persistent issue in many nations, and repeated attempts to promote diversity in the Australian arts community have had limited impact, suggesting the need for new approaches. Drawing on data from a 4‐year longitudinal study of students from ages 8 to 18 (n = 6,492) in government schools, we examine school students' aspirations for careers in the arts. Arts‐related careers were popular among students, yet we found a distinct lack of diversity among those aspiring to such careers. Using logistic regression analysis we found that being female, high achieving, from an English‐speaking background, possessing high cultural capital, and attending advantaged schools were significant predictors of interest in the arts, suggesting the likely reproduction of existing patterns of participation. We argue that initiatives within schools are essential to disrupting these patterns and building the capacity of a more diverse range of students to aspire to careers in the arts. 相似文献

Defaults (i.e., options that become effective without an active choice) have been found to be powerful tools to influence decision‐making in a range of behavioral domains. However, seemingly conflicting assumptions have been expressed regarding the interplay of defaults with individual attitudes. Whereas some expect attitude‐conditional effects (i.e., a statistical default‐by‐attitude interaction), others assume an attitude‐unconditional effectiveness of defaults (i.e., statistically additive effects). Integrating both assumptions, we argue that the interplay of defaults and attitudes depends on what is considered a default effect. Specifically, whereas default acceptance is likely to be attitude‐conditional, we predicted that defaults and attitudes would add up in explaining people's actual choices. We tested these hypotheses in an online shopping scenario presenting environmentally friendly or conventional default products to 231 participants. Participants’ environmental attitude was assessed with the General Ecological Behavior scale and actual product choices were identified if participants rejected a given default product. In line with our hypotheses, default acceptance was predicted by a default‐by‐attitude interaction. In contrast, actual environmentally friendly product choices were found to be an additive function of defaults and participants’ environmental attitude. From an applied perspective, our findings suggest that defaults can readily be applied even in attitude‐heterogeneous target populations. Concurrently, however, our findings also speak of the importance of people's attitudes for understanding individual decision‐making. 相似文献

ABSTRACTSchool-based mental health services are those delivered by school-employed and community-employed providers in school buildings. With the implementation of provisions of the Patient Protection and Affordable Care Act (2010) that funds school-based health centers, school-based mental health services could become more broadly available in communities throughout the United States. Playing a pivotal role in promoting models for school-based services that maximize benefits to children and adolescents while making efficient use of communities' mental health resources are school psychologists. School psychologists, who recognize and respect the separated development of school and community mental health professions, can foster school–agency partnerships to coordinate children's mental health services that are comprehensive, child centered, family focused, and culturally competent. In this article, we provide three case examples using the Participatory Culture-Specific Intervention Model (B. K. Nastasi, R. B. Moore, & K. M. Varjas, 2004) as exemplars for the implementation of community partnerships providing comprehensive culturally and contextually relevant school-based mental health services. 相似文献

Psychophysical experiments conducted remotely over the internet permit data collection from large numbers of participants but sacrifice control over sound presentation and therefore are not widely employed in hearing research. To help standardize online sound presentation, we introduce a brief psychophysical test for determining whether online experiment participants are wearing headphones. Listeners judge which of three pure tones is quietest, with one of the tones presented 180° out of phase across the stereo channels. This task is intended to be easy over headphones but difficult over loudspeakers due to phase-cancellation. We validated the test in the lab by testing listeners known to be wearing headphones or listening over loudspeakers. The screening test was effective and efficient, discriminating between the two modes of listening with a small number of trials. When run online, a bimodal distribution of scores was obtained, suggesting that some participants performed the task over loudspeakers despite instructions to use headphones. The ability to detect and screen out these participants mitigates concerns over sound quality for online experiments, a first step toward opening auditory perceptual research to the possibilities afforded by crowdsourcing. 相似文献

In this discussion of Bob Bartlett’s compelling paper “Time-Soaked,” I shift attention away from the vivid account of the interpersonal dynamics between Bartlett and his patient to describe the perspectives offered by theories of social memory and transgenerational haunting. I attempt to speak for and convey the voices and vulnerabilities of previous generations that I argue—if heard within the analytic dyad—can further inform and deepen the therapeutic endeavors undertaken by Bartlett and his patient. 相似文献
