Intervening on causal systems can illuminate their underlying structures. Past work has shown that, relative to adults, young children often make intervention decisions that appear to confirm a single hypothesis rather than those that optimally discriminate alternative hypotheses. Here, we investigated how the ability to make informative causal interventions changes across development. Ninety participants between the ages of 7 and 25 completed 40 different puzzles in which they had to intervene on various causal systems to determine their underlying structures. Each puzzle comprised a three- or four-node computer chip with hidden wires. On each trial, participants viewed two possible arrangements of the chip's hidden wires and had to select a single node to activate. After observing the outcome of their intervention, participants selected a wire configuration and rated their confidence in their selection. We characterized participant choices with a Bayesian measurement model that indexed the extent to which participants selected nodes that would best disambiguate the two possible causal structures versus those that had high causal centrality in one of the two causal hypotheses but did not necessarily discriminate between them. Our model estimates revealed that the use of a discriminatory strategy increased through early adolescence. Further, developmental improvements in intervention strategy were related to changes in the ability to accurately judge the strength of evidence that interventions revealed, as indexed by participants' confidence in their selections. Our results suggest that improvements in causal information-seeking extend into adolescence and may be driven by metacognitive sensitivity to the efficacy of previous interventions in discriminating competing ideas. 相似文献

The role of attitudes and beliefs in differential health care utilisation among Chinese in Singapore
Abstract One hundred and twenty-eight Chinese patients at two Western medical practices and two Chinese medical practices in Singapore completed a questionnaire regarding perceptions of illnesses. Health beliefs and attitudes towards different medical practitioners. Results indicate significant differences between those who consult only allopathic physicians (Western doctors) and those who consult both practitioners of traditional Chinese medicine (sinsehs) and Western doctors. Individuals consulting both Western doctors and sinsehs perceived a smaller proportion of “general” illness attributes (those found in both Western and Chinese medicine) to be relevant to specific diseases and showed greater endorsement of Chinese health beliefs than did individuals seeking help only from Western doctors. Also individuals consulting both types of practitioners expressed less satisfaction with the doctor's treatment than did those consulting only Western doctors and also rated sinsehs as more concerned with patient well-being and as listening more to their patients. 相似文献

An ad hominem fallacy is committed when an individual employs an irrelevant personal attack against an opponent instead of addressing that opponent’s argument. Many discussions of such fallacies discuss judgments of relevance about such personal attacks, and consider how we might distinguish those that are relevant from those that are not. This paper will argue that the literature on bias and testimony can helpfully contribute to that analysis. This will highlight ways in which biases, particularly unconscious biases, can make ad hominem fallacies seem effective, even when the irrelevance is recognized. 相似文献

Evidence from past studies indicates that adults and children with Obsessive-Compulsive Disorder (OCD) and Tourette syndrome (TS) experience subtle neuropsychological deficits. Less is known about neuropsychological functioning of children and adolescents with a symptom course consistent with the PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infection) subgroup of OCD and tics. To provide such information, we administered three tests of attention control and two of executive function to 67 children and adolescents (ages 5–16) diagnosed with OCD and/or tics and a symptom course consistent with the PANDAS subgroup and 98 healthy volunteers (HV) matched by age, sex, and IQ. In a paired comparison of the two groups, the PANDAS subjects were less accurate than HV in a test of response suppression. Further, in a two-step linear regression analysis of the PANDAS group in which clinical variables were added stepwise into the model and in the second step matching variables (age, sex, and IQ) were added, IQ emerged as a predictor of performance on this task. In the same analysis, ADHD diagnosis and age emerged as predictors of response time in a continuous performance task. Subdividing the PANDAS group by primary psychiatric diagnosis revealed that subjects with TS or OCD with tics exhibited a longer response time compared to controls than subjects with OCD only, replicating previous findings within TS and OCD. This study demonstrates that children with PANDAS exhibit neuropsychological profiles similar to those of their primary psychiatric diagnosis. 相似文献

This investigation focused on relationships among sexual assault, self-blame, and sexual revictimization. Among a female undergraduate sample of adolescent sexual assault victims, those endorsing greater self-blame following sexual assault were at increased risk for sexual revictimization during a 4.2-month follow-up period. Moreover, to the extent that sexual assault victims perceived nonconsensual sex is permitted by law, they were more likely to blame themselves for their own assaults. Discussion focuses on situating victim-based risk factors within sociocultural context. 相似文献

This study utilized a factorial survey design to assess attitudes toward affirmative action as a function of targeted group (Black, handicapped, or elderly persons), framing of the policy (with or without social justification), and institutional context (business, college, or social organization). Resistance to affirmative action was aroused more by policies specifying Blacks as the targeted group and by policies presented without justification. Supportive of the aversive racism framework, the level of resistance to the policies presented without justification for Blacks as the target group was higher than for all other targeted groups with or without justification. Implications for these findings for strategies to reduce negative attitudes toward affirmative action are discussed. 相似文献

This research examined deviant talk during summer residential treatment using peer nominations and extensive field observations.
Participants were 239 youth (M
age = 12.62, SD = 2.60; 67% male), nested in 26 treatment groups. Deviant talk was present in this setting, showed individual differences,
and increased over time, especially for younger boys. As expected, its relationship to treatment response was moderated by
peer behavior. Initial levels of individual deviant talk were related to clinical improvement, but primarily when peer deviant
talk was low. Initial levels of peer deviant talk were related to higher than expected end of treatment aggression, especially for youth who were high in deviant
talk. Deviant talk effects were observed for staff impressions of change and observations of aggression and adjustment. Initial
antisocial behavior affected whether individual or peer levels of deviant talk more heavily influenced treatment response.
Implications for clinical assessment and treatment monitoring are discussed. 相似文献

We suggest that employees’ perceptions of organizational support (POS) are not solely a product of independent evaluations of treatment offered by the organization, but are also shaped by the social context. We argue that coworkers will directly (through inquiry via cohesive friendship and advice ties) and indirectly (through monitoring of employees structurally equivalent in advice and friendship networks) affect employees’ perceived organizational support. Network studies in the admissions department of a large public university and a private company specializing in food and animal safety products indicate that employees’ POS are similar to those of coworkers with whom they maintain advice relationships as well as to those who hold structurally equivalent positions in organizational friendship and advice networks. Our work contributes to organizational support theory by developing and testing a theoretical explanation for the relationship between the social context and perceptions of support among employees. Implications for research and practice are offered. 相似文献
