Attention deficit hyperactivity disorder (ADHD) is characterized by deficient self-regulation, poor attentional control, and poor response inhibition. To date, however, the extent to which these deficits affect basic interference control remains a matter of controversy. Secondly, ADHD has been reported to be associated with arithmetic deficits. It remains unclear whether such deficits are a secondary consequence of the above-mentioned characteristics of ADHD or whether basic numerical magnitude representations are also affected. In the present study we attempted to investigate these issues using a basic numerical interference paradigm.

Nine- to twelve-year-old children with ADHD-C (attention-deficit hyperactivity-disorder combined type) and control children without ADHD (each n = 16) were presented with two digits of possibly different physical sizes (e.g., 3 7). This numerical Stroop task requires subjects to make a magnitude classification concerning either the physical or the numerical stimulus dimension. The irrelevant dimension can be congruent (same response), incongruent (different response), or neutral (no response association).

Children with ADHD-C performed worse than control children in most analyses. The most important finding was a significant interaction of congruity effects with group in the numerical comparison task. Children with ADHD-C tended to show larger congruity and interference effects than controls, and these were not attributable to a speed-accuracy trade-off.

The results might reflect differential processing speeds, or a different degree of automatic activation of physical and numerical magnitudes in children with and without ADHD-C. Alternative explanations, such as insufficient inhibition of selective (domain-specific) attention are also discussed.  相似文献

The efficacy of cognitive‐behavioral therapy in multi‐cultural primary care patients with longstanding backache is not evaluated. The purpose of this study was to investigate the outcome of a four weekly‐treatment given by primary care physicians regarding pain‐related worry, depression and severe pain and to determine which social, clinical or gender factors were associated with outcome.The study group consisted of 245 patients in consecutive order from 19 countries, 18 to 45 years, entering rehabilitation program because of longstanding backache. Prevalences of pain‐related worry and depression and severe pain was counted and compared before and after. Logistic regression was used to calculate the odds (OR; 95% CI) for persistent pain‐related worry and/or persistent depression and severe pain (VAS ≥ 50). The prevalences of pain‐related worry and depression were both significantly lower after treatment (pain‐related worry 83% before vs. 38% after; depression 43% before vs. 31% after). Also the number of patients scoring ≥ 50 VAS was a little, but significantly, fewer (68% vs. 61%). Use of interpreter doubled the risk of having persistent pain‐related worry (OR 2.1; 95% CI 1.1–4.1) but the risk was not significant regarding persistent depression (OR 1.8; 0.6‐5.4). The rating of VAS rating ≥ 50 after treatment was twice as high, OR 2.3 (95% CI 1.1–4.6) in the 38–45 year old age group. To conclude, a focus on pain ideas reduced pain‐related worry and depression in these patients with various sociocultural backgrounds and longstanding backache.  相似文献

Norenzayan's effort to integrate genetic and cultural evolution is a welcome advance over previous efforts, as is the attention he devotes to different levels of analysis from cognitive mechanisms to large group interactions. The scope of Norenzayan's argument, however, is bound to leave many scholars of religion feeling uneasy. The content of his model, which is most likely over specified, will need further testing in light of historical evidence. Comparison of Big Gods with Robert Bellah's Religion in Human Evolution (2011) highlights some of the choices Norenzayan made in designing his model and suggests ways it could be elaborated. Historians of religion who would like to help test his model could keep an eye out for ‘watcher mechanisms’ that might play more of a role than ‘moralizing Big Gods’ in some traditions and, thus, potentially offer an alternative route to large, anonymous, yet stable groups.  相似文献

This review article addresses the historical argument of Norenzayan's Big Gods. It questions the claim that there is enough historical evidence to support the thesis that gods, who are observing human behaviour from high, enable societies to grow beyond the stage of face-to-face groups.  相似文献

We used an intersectional minority stress perspective to examine the association between family/cultural stress and mental health among substance-using Mexican-Americans. Employing a unique longitudinal sample of 239 socioeconomically disadvantaged, non-injecting heroin-using Mexican-Americans from San Antonio, Texas, we examined how culturally relevant stressors are related to depression and suicidal ideation. First, we identified depression and suicidal ideation prevalence rates for this disadvantaged sample. Second, we determined how cultural stress is experienced over time using stress trajectories. Third, we evaluated how family/cultural stressors and stress trajectories are related to depression and suicidal ideation outcomes. Results showed high rates of baseline depression (24 %) and suicidal ideation (30 %). We used latent class growth analysis to identify three primary stress trajectories (stable, high but decreasing, and increasing) over three time points during 1 year. We found that the increasing stressors trajectory was associated with higher rates of depression and suicidal ideation, and that stress trajectories had unique relationships with mental illness. We also showed that baseline stressors, sum stressors, and high but decreasing stressors maintained positive associations with mental illness after controlling for baseline depression. Our results highlight the importance of focusing on within-group, culturally specific stressors and addressing both operant and cumulative stressors in the study of mental health for marginalized populations and suggest the importance of early intervention in minimizing stressors.  相似文献

The voting behavior literature has advanced two prominent theoretical models of partisanship: the social psychological and rational models. Implicit to both stylized models is the assumption that all partisans process information similarly. Yet, growing research in psychology suggests that individuals possess different motivations when evaluating information. We propose that the applicability of the stylized models of partisanship is conditioned on individuals' need for cognition (NFC) and need for affect (NFA), with the social psychological model being most applicable to individuals who have a high NFA and the rational model most applicable to those with a high NFC. To test this proposition, we fielded a survey in which respondents who identified with the two major political parties in the United States (Democrat or Republican) were randomly assigned factual information that depicted either their party or their opposing party in a negative light. Respondents were then asked to assess the actions of that party and subsequently evaluate both political parties. We find evidence that is generally consistent with the proposition that the stylized models of partisanship are conditionally dependent on the extent to which individuals possess a need to engage in effortful thinking or a need to seek out emotions.  相似文献

ABSTRACT

Careers provision for young people in the UK is being re-formulated on the basis of a central role for career websites but this policy is based on unproven assumptions about their value. In this article we consider the use and impact of the two main career websites in Scotland on pupils' career management skills. We found that pupils at risk of not achieving positive post-school destinations were less likely to use the websites, as were minority ethnic pupils. Although similar in functions, the two websites differed in their effect: one had no impact while the other impacted on only one aspect of pupils' career management skills. Careers policy needs to be informed by more extensive research on career websites.  相似文献

对信息源的正向跟随倾向对决策效果的影响*   总被引:1,自引:0,他引:1  
采用实验研究的方法,检验了二元选择情形下高准确率信息源(准确率x >50%)和低准确率信息源(准确率为1?x)对决策者预测效果的影响。尽管从逻辑上二者从准确率层面具有完全相等的信息价值,然而研究结果显示,决策者更倾向于采用正向跟随而非逆向跟随的方式处理来自信息源的信息。这导致低准确信息源的价值未能得以充分利用。学习和信息源的规范性对该信息处理倾向起到调节作用。  相似文献
