There are large individual differences in the degree of association between the accuracy of memories and subjective confidence in those memories. Are these differences stable within the same test, and between alternate forms of a test? In Experiment 1, college students were tested on 3 recognition memory tasks, then retested 2 weeks later on alternate forms of the same tasks. The relationship between confidence judgments and recognition performance displayed low split-half stability and low alternate-forms stability. A second experiment with elderly adults replicated these findings. In a third experiment, college students recalled answers to general knowledge questions and rated confidence in the correctness of each answer. Individual differences in the association between confidence and recall performance were not stable across the odd- and even-numbered items on the test. These data indicate the need for the development of procedures that will produce stable estimates of individuals’ metacognitive accuracy.  相似文献

The New World primates Callicebus moloch and Saimiri sciureus differ markedly in life modes. Physiological responsiveness (heart rate, cortisol) of these related taxa was compared in two situations that differed in the presumed degree of stress imposed, exposure to a novel environment and physical restraint. In both situations, Saimiri exhibited higher initial levels of heart rate and corticosteroids. In addition, the species differed in their patterns of response to both situations. Saimiri maintained initial heart rate levels across a 1-hour exposure period, whereas Callicebus showed a marked and continuous decline in heart rate. Adrenocortical activity increased in both species in response to test situations, but the elevations in plasma corticosteroids were substantially greater for Saimiri than for Callicebus. The results indicate that the species differ with respect to organization of physiological regulatory systems in a manner consistent with behavioral contrasts between them.  相似文献

There is a need for practical methods of reinforcer assessment that systematically track ongoing changes in clients' preferences. In this study, the effects of a time-efficient reinforcer assessment package were evaluated in a multiple baseline across 3 preschoolers with autism, comparing individualized item selections by experienced teachers with children's presession preferences for items of various sensory qualities. Systematic assessment of children's reinforcers for correct responding virtually eliminated nontargeted maladaptive behaviors, as well as yielding expected improvements in accuracy. The powerful side-effects of potent reinforcers underline the importance of increased attention to reinforcer assessment in research and practice.  相似文献

Eating disorders occur in diverse populations, and discrimination may be a specific factor that is related to higher eating disorder psychopathology among marginalized individuals. To evaluate the current evidence on this topic, a meta-analysis was used to quantitatively synthesize the literature on discrimination and eating disorder psychopathology across a heterogeneous range of studies. Searches were conducted in peer-reviewed journals and accessible unpublished dissertations of all years through January 2020. Studies were coded by two authors using a tailored coding form, and zero-order bivariate correlations were used as effect size measures. There were 55 cross-sectional studies extracted for inclusion in the meta-analysis. Results showed a small-to-medium association between discrimination and eating disorder psychopathology that was consistent across domains. Effect sizes were typically higher for weight discrimination. For binge eating and general eating disorder pathology, effects were smaller in studies that had larger proportions of women, and for binge eating only, effects were higher in college samples. These findings could suggest that discrimination represents a contributory factor related to eating disorder psychopathology across types of discrimination and eating disorder psychopathology. Implications are discussed for future research on discrimination and psychopathology including possible mechanisms.  相似文献

In his ‘Could Extended Objects Be Made Out of Simple Parts?: An Argument for “Atomless Gunk’’, Dean Zimmerman defends the claim that no physical object has a complete decomposition into simples but instead has among its parts a piece of ‘atomless gunk’ His argument for this claim rests in part upon a theory of the impenetrability of physical objects. In that theory, Zimmerman distinguishes ‘[t]he sort of impenetrability that is a part of the concept of’ a physical object from ‘a power to resist the pressure of other objects’. He says that impenetrability is but ‘an essential inability’ of two physical objects to occupy one and the same region of space, an essential inability that is not a power of one physical object to exert repulsive forces on others in its vicinity. I argue that this theory of impenetrability is false and that Zimmerman's argument for the existence of ‘atomless gunk’ fails.  相似文献

The authors conducted a workshop at a family therapy conference in South Africa in 1997 to explore the use of healing rituals in grief work. There were two levels involved: First, an experiential workshop, and, second, a metalevel in exploring the use of rituals as a rite of passage to facilitate transitions. A draft of the authors' paper was sent to all participants for their comments, which are included in the text.  相似文献

In Study 1 college students (47 men, 104 women) watched Pokémon cartoons, and afterward they rated one of four trainers (persons who train creatures called Pokémon) on 28 characteristics. James, the male “bad” trainer, was rated lowest of four trainers on “masculine” traits including strength, assertiveness, certainty, and being a leader. Jesse, the female “bad” trainer, was rated as sexiest and most aggressive. In Study 2 sixty-two elementary school children (28 girls, 34 boys) were individually interviewed. Fewer than 50% of the children could name a female Pokémon, and participants were more likely to choose a boy than a girl as a favorite trainer. Male Pokémon and trainers may be more central to the cartoon, and counter-stereotypical gender portrayals may be one way to portray a “bad” character even more negatively.  相似文献
