Task-set reconfiguration with predictable and unpredictable task switches   总被引:3,自引:0,他引:3  
Participants switched frequently between high/low and odd/even classification of a digit. The interval between a task cue and the next digit varied between blocks. In Experiment 1, the task switched predictably every two, four, or eight trials. In Experiment 2, switching predictably every four trials was compared with random switching. With predictable switching, the cost was limited to the first trial of a run. Random switching produced a more gradual approach to asymptotic performance. After one performance, control processes attenuate the resulting change in task-set bias if a further switch is likely, but this strategic modulation is soon overwhelmed by task-set priming through further performances. Preparation reduced switch costs but not interference from the irrelevant attribute: Control of interference appears to be reactive, not proactive. Switch costs did not increase with run length, suggesting that retrieval of the task set last associated with the stimulus did not contribute to switch costs.  相似文献

This article explores affect, colonial privilege, and the cultural politics of national commemoration in Aotearoa New Zealand. Based on focus-group interviews around two major national days, we examine means through which feelings and emotions are deployed in ways that enable the reproduction of social advantage. Situating affect within patterns of relationship, four interrelated affective-discursive practices are explored. In relation to Waitangi Day, agents tend to work under the rubric of anger and confusion. For Anzac Day, being grateful and moved shapes the interaction, although participants often indicate preferences towards “having a day off.” Given the colonial context in which these practices circulate, analysis observes the associated freedom and ease by which affective-discursive privilege is (re)produced. Often incongruent and rarely challenged, privilege allows associated actors to do what they want, when they want, however they want. This affective climate authorizes the ongoing reproduction of, and justification for, membership to a higher-status ethnic group of which unearned opportunities and entitlements remain its everyday, expected currency.  相似文献

Children with reading difficulties and children with a history of repeated ear infections (Otitis Media, OM) are both thought to have phonological impairments, but for quite different reasons. This paper examines the profile of phonological and morphological awareness in poor readers and children with OM. Thirty‐three poor readers were compared to individually matched chronological age and reading age controls. Their phonological awareness and morphological awareness skills were consistently at the level of reading age matched controls. Unexpectedly, a significant minority (25%) of the poor readers had some degree of undiagnosed mild or very mild hearing loss. Twenty‐nine children with a history of OM and their matched controls completed the same battery of tasks. They showed relatively small delays in their literacy and showed no impairment in morphological awareness but had phonological awareness scores below the level of reading age matched controls. Further analysis suggested that this weakness in phonological awareness was carried by a specific weakness in segmenting and blending phonemes, with relatively good performance on phoneme manipulation tasks. Results suggest that children with OM show a circumscribed deficit in phoneme segmentation and blending, while poor readers show a broader metalinguistic impairment which is more closely associated with reading difficulties.  相似文献

In February 2012, the Obama White House endorsed a Privacy Bill of Rights, comprising seven principles. The third, “Respect for Context,” is explained as the expectation that “companies will collect, use, and disclose personal data in ways that are consistent with the context in which consumers provide the data.” One can anticipate the contested interpretations of this principle as parties representing diverse interests vie to make theirs the authoritative one. In the paper I will discuss three possibilities and explain why each does not take us far beyond the status quo, which, regulators in the United States, Europe, and beyond have found problematic. I will argue that contextual integrity offers the best way forward for protecting privacy in a world where information increasingly mediates our significant activities and relationships. Although an important goal is to influence policy, this paper aims less to stipulate explicit rules than to present an underlying justificatory, or normative rationale. Along the way, it will review key ideas in the theory of contextual integrity, its differences from existing approaches, and its harmony with basic intuition about information sharing practices and norms.  相似文献

Bhutanese refugees represent one of Canada’s most recent immigrant populations, and little is known about their dietary traditions and habits. The purpose of this study was to improve the wellbeing and health of re-settled refugee Bhutanese women by understanding how culturally informed postpartum food choices are practiced post-migration. As part of a larger community-based participatory research project, semi-structured interviews were conducted with 12 Bhutanese refugee women. The traditional dietary choices that Bhutanese women revealed to be important in the postpartum period were organized into five themes: (1) “foods consumed as part of a regular healthy diet,” (2) “foods to regain strength and heal the body,” (3) “foods to ward off back and joint pain,” (4) “foods to promote lactation,” (5) “foods avoided due to negative effects.” Traditional foods and culturally situated beliefs in the postpartum period play a significant role in the lives of Bhutanese women. Healthcare workers in countries of re-settlement should work with the traditional health and nutritional beliefs of women in this community in order to provide optimal dietary and health recommendations.  相似文献

Religious involvement has long been argued to have protective effects for negative behavioral health outcomes for vulnerable youth. This study builds on the existing resilience literature and need for more studies that examine protective factors associated with behavioral health. A sample of 638 low-income African American adolescents in Chicago to examine within group variations of the influence of religious involvement on delinquency, school engagement, substance use and sexual risk behaviors, and whether such relationships differ by gender, sexual orientation, and socioeconomic status. Logistic regression findings documented that greater religious involvement was protective with regards to lower rates of delinquency, drug use, risky sexual behaviors and higher rates of school engagement, and that gender, sexual orientation and socioeconomic status varied for several of these relationships. Overall findings are discussed with regards to future research.  相似文献

Parents are perhaps the most direct and profound influences on children’s development of emotional competence. For example, how and what emotions parents express in the family has implications for children’s ability to understand and regulate their emotions. What is less well understood is what potential environmental or contextual factors impact parents’ emotional expressiveness, particularly in high-risk samples prone to atypical emotional expressiveness (e.g., deficits in the production and recognition of emotional expressions). The present longitudinal study examined the association between life changes and parents’ expression of positive and negative emotions, as well as, how these associations changed over time in a sample of maltreating mothers. Eighty-eight mothers with a substantiated history of physical abuse completed measures of emotional expressiveness and life changes experienced over the past 6 months when their children were in preschool, kindergarten, and first grade. Results indicated that life changes decreased over time, while parental emotional expressiveness remained stable. Moreover, life changes were associated across time with the expression of negative emotions, but were unrelated to expressions of positive emotions. Findings have important implications for understanding emotional expressiveness in high-risk samples.  相似文献

Cognitive-behavioral therapy (CBT), consisting of exposure and response prevention (EX/RP), is both efficacious and preferred by patients with obsessive–compulsive disorder (OCD), yet few receive this treatment in practice. This study describes the implementation of an Internet-based CBT program (ICBT) developed in Sweden in individuals seeking OCD treatment in New York. After translating and adapting the Swedish ICBT for OCD, we conducted an open trial with 40 adults with OCD. Using the RE-AIM implementation science framework, we assessed the acceptability, feasibility, and effectiveness of ICBT. The Yale–Brown Obsessive Compulsive Scale (Y-BOCS) was the primary outcome measure. Of 40 enrolled, 28 participants completed the 10-week ICBT. In the intent-to-treat sample (N = 40), Y-BOCS scores decreased significantly over time (F = 28.12, df = 2, 49, p < . 001). Depressive severity (F = 5.87, df = 2, 48, p < . 001), and quality of life (F = 12.34, df = 2, 48, p < . 001) also improved. Sensitivity analyses among treatment completers (N = 28) confirmed the intent-to-treat results, with a large effect size for Y-BOCS change (Cohen’s d = 1.38). ICBT took less time to implement than face-to face EX/RP and participants were very to mostly satisfied with ICBT. On a par with results in Sweden, the adapted ICBT program reduced OCD and depressive symptoms and improved quality of life among individuals with moderate to severe OCD. Given its acceptability and feasibility, ICBT deserves further study as a way to increase access to CBT for OCD in the United States.  相似文献

Objective: The study set out to investigate socio-economic, biomedical, health and behavioural and psychological factors in childhood and adulthood associated with the prevalence of asthma in adulthood, drawing data from The National Child Development Studies (NCDS), a birth cohort in the UK.

Design: The National Child Development Study, a nationally representative sample of 17,415 babies born in Great Britain in 1958 and followed up at 7, 11, 33 and 50 years was used.

Main Outcome Measure: The prevalence of asthma at age 50 was the outcome measure. The analytic sample consists of 5118 participants with complete data on a set of measures at birth, at ages 7, 11, 33 and 50 years.

Results: Using logistic regression analyses, results showed that childhood asthma (OR = 6.77: 4.38–10.48, p < .001) and respiratory symptoms (OR = 1.83: 1.18–2.86, p < .01), maternal smoking during pregnancy (OR = 1.26: 1.00–1.59, p < .05), Body and Mass Index (BMI) (OR = 1.03: 1.02–1.05, p < .001), traits Neuroticism (OR = 1.13: 1.01–1.21, p < .05) and Conscientiousness (OR = 0.76: 0.76–0.96, p < .01), as well as sex (OR = 1.49: 1.15–1.94, p < .001) were all significantly associated with the prevalence of asthma in adulthood.

Conclusion: The study shows that both childhood and adulthood psychological and sociological factors are significantly associated with the prevalence of asthma in adulthood, though more work need to be done in this area.  相似文献

A.F.科赫教授因其对康德与德国观念论(尤其是黑格尔)的深入研究而著名,此外他非常熟悉分析哲学与实用主义的当代成果。这使他能够以一种不同于其前辈诠释者的方式来理解德国哲学,并以一种完全不同于布兰顿和麦克道威尔这两位当代著名的分析哲学家的方式对大西洋两岸的两种不同的哲学传统进行让人瞩目的融合。从科赫教授身上我们可以看到,一个在欧陆哲学传统中成长起来的哲学家如何吸收和消化分析哲学的成果并尝试建立起一种新的思想方式。  相似文献
