The ability of 4 rhesus monkeys (Macaca mulatta) to understand the causal connection between seeing and knowing was investigated. The subjects were tested to determine if they could discriminate between information provided by experimenters who randomly alternated between roles of guesser and knower. In a series of tests, the knower either hid food under 1 of 3 cups or watched as someone else hid the food. The guesser waited outside the room or covered her or his head until the food was hidden. The subjects watched this procedure occur but could not see which cup the food was hidden under. The knower pointed to the correct cup while the guesser pointed to an incorrect one. None of the macaques provided any evidence that they realized the different states of knowledge possessed by the guesser and knower. The results are consistent with the hypothesis that rhesus macaques are incapable of making inferences about the mental states of others. 相似文献

Preferential-looking studies suggest that by 2 months of age, infants may have knowledge about some object properties, such as solidity. Manual search studies of toddlers examining these same concepts, however, have failed to provide evidence for the same understanding. Investigators have recently attempted to reconcile this disparity but failed to control for the visual novelty of test outcomes. The current design corrected this problem and also tested toddlers' predictions of the object's location. The task involved the same events and apparatus that have been used in manual search tasks but used looking as the dependent measure. Children looked longer when an agent opened the correct door and found no ball than when an incorrect door was opened to reveal no ball. A 2nd experiment indicated that children's preferential-looking performance did not differ from that in manual search tasks simply because additional response time had been allowed to respond. Previous comparisons of looking versus reaching tested children's postdiction response to an object in an unexpected location, but these findings indicate that toddlers can predict where the object should be. 相似文献

There is little information available about how and why parents of children with autism spectrum disorders (ASD) make decisions regarding which of the many available treatments to implement with their children. Given the lack of available information regarding treatment efficacy, it is likely that parents' beliefs about child development, interpretation of the symptoms of ASD, its etiology and course, and their experiences with the health system influence treatment decisions. This article addresses these issues within the context of cultural influences. We review the small body of existing literature regarding cultural influences on decisions regarding ASD and draw implications for the study and treatment of ASD from the larger body of literature on culture and other health conditions of childhood. In addition to examining the potential for differences in clinical presentation by culture and different experiences with the healthcare system, we use Kleinman's framework of questions for understanding the role of culture in the interpretation and treatment of ASD. These questions address interpretation of symptoms and beliefs about their cause, course, and treatment. Finally, we present specific language for clinicians to use in discussion with families with different cultural beliefs about the use of less traditional treatment strategies. 相似文献

Abstract A qualitative research method based on action theory is proposed and illustrated for use in health psychology and health promotion research. Action refers to the goal-directed and intentional behaviors of individual and groups. Action theory has the advantage of using the perspectives provided by manifest behavior, internal processes, and social meaning in the analysis of action. In this article, the actions under consideration are the health-related conversations of parents and their adolescent children. The approach is premised on an understanding of health promotion as a family task constructed through actions such as conversations between family members. Health conversations in two parent-adolescent dyads are used to illustrate the method. The analysis includes the identification of goals, functional steps, and elements and their relation to the family health promotion project. Specific attention is paid to data gathering and analysis issues and their implications for health promotion research. 相似文献

In this research, hierarchical linear modeling (HLM) was used to address how school context influences the likelihood of transitioning between stages of cigarette smoking as well as modifies the individual-level risk factor of self-regulation. Survey data were collected from 25,186 middle and high school students attending 38 public schools in Kentucky. Results show that students are less likely to increase use in schools with higher levels of teacher discipline and faculty involvement. The analyses of the multi-level interactions between self-regulation and school context reveal that students possessing low emotional regulation are more likely to initiate experimental smoking in schools with poor levels of discipline and involvement than similar types of students in schools with higher levels of these characteristics. This study illustrates how psychological risk factors for substance use may vary across social environments. 相似文献

We examined continuity and change in emotional reactiviy as assessed by hypothalamic–pituitary–adrenal (HPA) activity in rhesus monkeys. Plasma samples were obtained from mother-peer–reared and surrogate-peer–reared monkeys and assayed for cortisol concentrations at 5 time points in infancy. Both plasma and saliva samples were collected for cortisol assay from the same monkeys as 1-, 2-, and 3-year-old juveniles, respectively. Plasma cortisol concentrations increased during the first 5 months of life and decreased from 1 to 3 years of age. Females consistently had higher plasma cortisol concentrations than males. Plasma cortisol concentrations were lower in surrogate-peer–reared than mother-peer–reared monkeys during the first month of life. Juvenile plasma cortisol concentrations were significantly correlated with infant cortisol levels at all but the earliest time point. Analysis of salivary cortisol from a subset of animals showed a similar age-related decline and the presence of a significant rearing effect, with lower concentrations in surrogate-peer–reared juveniles, but no sex difference. Salivary and plasma cortisol concentrations in these animals were significantly correlated. 相似文献

Cognitive impairments are central to schizophrenia and could mark underlying biological dysfunction but efforts to detect genetic associations for schizophrenia or cognitive phenotypes have been disappointing. Phenomics strategies emphasizing simultaneous study of multiple phenotypes across biological scales might help, particularly if the high heritabilities of schizophrenia and cognitive impairments are due to large numbers of genetic variants with small effect. Convergent evidence is reviewed, and a new collaborative knowledgebase - CogGene - is introduced to share data about genetic associations with cognitive phenotypes, and enable users to meta-analyze results interactively. CogGene data demonstrate the need for larger studies with broader representation of cognitive phenotypes. Given that meta-analyses will probably be necessary to detect the small association signals linking the genome and cognitive phenotypes, CogGene or similar applications will be needed to enable collaborative knowledge aggregation and specify true effects. 相似文献

An analysis of traditional Jewish texts yields neither the capitalist notion of medicine nor the socialist one. Neither alternative is sufficient to ground the respect for the sanctity of the human person as a being created in the image of God that is so rationally appealing. That is why the Jewish ethical tradition, which is based on this respect for the sanctity of human personhood, both individual and collective, is so attractive--if only for its insights, rather than its authority; its guidance, rather than its governance. 相似文献

The present study examined how mothers signal shared feeling-states to their infants. Affect attunement and imitation were investigated cross-culturally in 39 mother-infant dyads from Sweden (N = 22) and the former Yugoslavia (N = 17) during the first year of life. Video-recordings of playful interaction between mothers and their infants were analysed using the Affect Attunement Protocol. A significant negative association between imitation and age was found, while there was a significant positive association between affect attunement and age. Single occurrences of affect attunement appeared already at two or three months of age, and by 6 months of age episodes of affect attunement were more common than imitation. Frequencies of imitation and affect attunement were similar cross-culturally and in terms of gender, although there was a significant interaction between age and gender. The results suggest that the signalling of shared feeling-states is not a static process. Mothers do not signal shared feeling-states in the same manner at different ages. Imitation is the most important process during the earliest months, but is superseded by affect attunement earlier than previously thought. The functional implications of this developmental variation are discussed. 相似文献
