Although it is well established that four-year-olds outperform three-year-olds on predicting behavior from false beliefs, this is only true when the false belief is coupled with a positive desire. Four-year-olds perform poorly in an otherwise standard false belief task when the protagonist's desire is to avoid rather than to approach a target. We account for this by assuming that the attribution of a false belief involves inhibitory processing. We present two versions of an inhibition model of successful belief-desire reasoning. 相似文献

Does Human Facial Attractiveness Honestly Advertise Health? Longitudinal Data on an Evolutionary Question 总被引:1,自引:0,他引:1
S. Michael Kalick Leslie A. Zebrowitz Judith H. Langlois & Robert M. Johnson 《Psychological science》1998,9(1):8-13
Inspired by the evolutionary conjecture that sexually selected traits function as indicators of pathogen resistance in animals and humans, we examined the notion that human facial attractiveness provides evidence of health. Using photos of 164 males and 169 females in late adolescence and health data on these individuals in adolescence, middle adulthood, and later adulthood, we found that adolescent facial attractiveness was unrelated to adolescent health for either males or females, and was not predictive of health at the later times. We also asked raters to guess the health of each stimulus person from his or her photo. Relatively attractive stimulus persons were mistakenly rated as healthier than their peers. The correlation between perceived health and medically assessed health increased when attractiveness was statistically controlled, which implies that attractiveness suppressed the accurate recognition of health. These findings may have important implications for evolutionary models. 相似文献

Second-, fourth-, and sixth-grade students of high or low reading ability and college students carried out a visual-search task in which they scanned a list of 10 words, looking for a target word which was changed every trial or remained constant during an entire session. Search time increased linearly with serial position, consistent with a serial self-terminating model of visual search. The search rate increased from 3.3 words/sec in the second grade to 8.4 words/sec in college. Reading ability was not a significant factor in any comparisons. These results on the development of visual-search ability agree with others in showing that with increasing age there is a marked increase in search speed. However, retarded readers are as competent as their age peers on this task, suggesting that reading dysfunction must be traced to other deficiencies. 相似文献

Recognition probes given before or after a series of letters presented at varying rates were used to evaluate perception and memory loss of order and item information. For both order and item information pre- and postprobe functions converged at fast rates of presentation. Performance decrement at fast rates is attributable to perceptual factors and is greater for order than for item information. 相似文献

Telepractice has emerged as a potentially effective means of preparing parents and educators as interventionists for children with autism spectrum disorder (ASD). The purpose of this study was to evaluate the use of telepractice to train interventionists to implement incidental teaching with preschool children with ASD. Three interventionists were taught to implement incidental teaching using a telepractice training package consisting of an online module, self-evaluation, and delayed performance feedback delivered via videoconferencing. A single-case multiple-baseline across-participant design was employed to evaluate the effects of the telepractice training package on interventionist acquisition and maintenance of incidental teaching. The distal effects of interventionist implementation of incidental teaching on child mands were also evaluated. Results showed that following the telepractice training program, interventionist implementation fidelity improved and child mands increased. Within six telepractice sessions, all interventionists reached the preset performance criteria of four consecutive sessions above 90 % fidelity. Changes in interventionist and child behaviors maintained at 2- and 4-week follow-up sessions. Taken together, these results suggest that telepractice is a promising method of providing instruction in incidental teaching to interventionists of young children with ASD. 相似文献

MATERNAL SELF‐REPORTED DEPRESSIVE SYMPTOMS AND MATERNAL CORTISOL LEVELS INTERACT TO PREDICT INFANT CORTISOL LEVELS 下载免费PDF全文

Three basic findings have emerged from research on maternal depressive symptoms and offspring hypothalamic–pituitary–adrenal functioning: (a) Mothers’ depressive symptoms are positively associated with their offsprings’ cortisol stress response, (b) numerous individual and interpersonal maternal characteristics moderate this association, and (c) maternal and infant cortisol levels are highly correlated. In combination, these findings have suggested that maternal cortisol levels may moderate the relation between maternal depressive symptoms and infant cortisol responsivity; the current study assessed this hypothesis. Participants were 297 mother–infant dyads who were recruited from the community. Maternal depressive symptoms were assessed via self‐report. Dyads participated in two differentially stressful infant challenges when infants were 16 and 17 months old. Mother and infant salivary cortisol was collected before and after challenges. Results indicate that maternal cortisol levels moderated associations between maternal depressive symptoms and infant cortisol levels across both challenges. Infants showed higher cortisol levels if their mothers had both higher depressive symptoms and higher cortisol levels, as compared to infants of mothers with higher depressive symptoms and lower cortisol, and to infants of mothers with lower depressive symptoms and either higher or lower cortisol levels. We discuss findings in relation to environmental and biological factors that may contribute to the intergenerational transmission of depressive symptoms. 相似文献

This article introduces the work of philosopher‐novelist Walker Percy to the Zygon: Journal of Religion and Science readership. After some biographical and contextual preliminaries, I suggest that the conceptual collecting feature to Percy's work is his critique of abstractionism manifest in a tripartite congruence of Cartesianism, derivatively misapplied science, and social atomism. 相似文献
