Using data from a sample of African-Americans, the present study examined the role of religious beliefs and behaviours in predicting changes in Spiritual Health Locus of Control (SHLOC), or beliefs about the role that God plays in a person’s health. A national sample of African-American adults was recruited using a telephone survey and re-contacted 2.5 years later. Overall, results indicated that both higher religious beliefs and behaviours predicted increases in Active SHLOC, or the view that one collaboratively works with God to maintain one’s health. However, only religious behaviours predicted increases in Passive SHLOC, or the view that because God is in complete control of health that one’s own behaviours are unnecessary. Among men, religious beliefs predicted strengthening Active SHLOC beliefs, while religious behaviours predicted growing Passive SHLOC beliefs. Among women, religious behaviours predicted strengthening Active and Passive SHLOC beliefs.  相似文献

Alcohol-Impaired Driving (AID) is rarely studied among Arab communities. As contacts between Arab and Western cultures grow, alcohol consumption and safety-related issues are emerging as a major public health concern. This paper examines factors influencing the decision to engage in AID in a sample of young Arab-Israeli bar patrons (n = 300, age 17–34), including both Muslims (n = 77) and Christians (n = 176); alcohol is prohibited for the former, but is normative for the latter. Studies of AID often use agent-oriented models, most notably the theory of planned behavior (TPB). The current study complements this tradition using the structure-oriented Social-Cultural (SC) model. Over 70% of participants reported engaging in AID after consuming 3–4 portions of alcohol. The TPB model proved to have significant explanatory power while most cultural factors, including religion, failed to gain statistical significance. The latter finding is counter-intuitive given the different status of alcohol in the cultures investigated. The TPB variable Personal Behavioral Control (PBC) and a specific sub-component of the subjective norms variable emerged as providing the greatest contribution to the model. The results support the robustness of TPB and demonstrate that beyond identifying idiosyncratic patterns structure-based models can be useful in refuting pre-conceived conceptions. Thus, both approaches should be utilized to inform policymaking. Governmental authorities, particularly in Israel, must consider the neglected issue of AID among Arab communities, including both Christians and Muslims.  相似文献

When facing potential conflicts, whether to make interventions is an important decision for air traffic controllers and vital for aviation safety and efficiency. While many task-related factors in influencing such decisions have been identified, the large portion of individual differences has remained insufficiently explained. This paper proposes that controllers with a more holistic thinking style will be more likely to make interventions because they envision more uncertainties in the system which can lead to a higher level of perceived risk and a greater likelihood to take proactive measures. To test these hypotheses, forty-two licensed controllers were invited to complete a questionnaire measuring holistic thinking style and later a conflict detection/resolution task. Multilevel regression analyses showed that (1) when the real risk level (the minimum lateral distance between two converging aircraft) dropped, controllers who think more holistically still tended to maintain a higher risk perception level (perceived likelihood of aircraft collision in the future) which lead to a higher intervention ratio and (2) even when real and perceived risk levels were controlled, those who think more holistically were more likely to make interventions. These findings are discussed with reference to literature in cognitive style, risk perception and workload management. Potential implications for personnel selection and training are also discussed.  相似文献

Effortful control (EC) is a form of self‐regulation characterized by inhibition of dominant responses in favour of more adaptive subdominant responses. In the present study, temperamental antecedents in infancy were examined in relationship to toddler EC. Parents reported on infant temperament at 6, 8, 10, and 12 months, using the regulatory capacity/orienting (RCO) factor of the Infant Behavior Questionnaire‐Revised. Laboratory indicators of this temperamental construct were also collected at each time point via the Temperament Laboratory Assessment. Relations between changes in temperament across the first year of life and toddler EC (mean age = 22 months) were examined using multilevel modelling. Parent‐reported RCO and the component subscale of cuddliness more specifically were the only temperamental variables that prospectively predicted toddler EC.

The International Intrusive Thought Interview Schedule (IITIS) was used to assess and compare the unwanted intrusive thoughts (UITs) reported in a group of patients with obsessive compulsive disorder (OCD) and a non-clinical group. Although all participants reported at least one type of intrusion, OCD patients experienced more intrusive thoughts than non-clinical participants, and this difference was statistically significant. In the OCD group, intrusive thoughts were more frequent, interfered more with daily life, were considered to be more important to get out of the mind, and were more difficult to stop than in non-clinical participants. The two groups did not differ significantly in terms of five appraisals of the most distressing intrusive thought. One appraisal (importance) was used far more by the OCD group than the non-clinical group. For three appraisals (intolerance of anxiety, need to control, and intolerance of uncertainty), the difference was smaller. Only two of the strategies for controlling the most upsetting intrusive thought (ritual and avoidance) were of value in differentiating between the two groups. The IITIS (an instrument used to assess intrusions in non-clinical samples) appears to be of value for the assessment of patients with OCD.  相似文献

尽管音乐训练影响许多认知加工,但这种广泛性影响背后的机制迄今仍不清楚。近年来,研究者认为音乐训练的迁移效应可能是通过执行功能起作用。本文将执行功能细分为抑制控制、工作记忆、认知灵活性三个核心成分,考察音乐训练对这三个成分的影响以及执行功能在音乐训练迁移效应中的中介作用。研究结果表明,音乐训练对执行功能不同成分的影响有不同特点。同时,前额叶结构与功能的变化在音乐训练影响执行功能的过程中发挥着重要作用。此外,关于执行功能在音乐训练迁移效应中的中介作用,目前研究还存在不一致的结果,未来研究应采用多种技术手段深入探讨这一问题。  相似文献

前瞻记忆和认知控制是人类认知能力的重要组成部分。Bugg等人(2013)发现前瞻记忆多重加工模型和双重认知控制理论具有共性。此后,越来越多的研究者关注认知控制在意图执行中和执行完成后的作用。本文对近年来关于前瞻记忆与认知控制的研究进行了梳理,发现认知控制对前瞻记忆的完成起支持作用,但二者也在脑机制层面存在差异。本研究能为未来更深入地探讨前瞻记忆的加工机制及生理基础提供新的视角。  相似文献

Research using clinical populations to explore the relationship between hemispheric speech lateralization and handedness has focused on individuals with speech and language disorders, such as dyslexia or specific language impairment (SLI). Such work reveals atypical patterns of cerebral lateralization and handedness in these groups compared to controls. There are few studies that examine this relationship in people with motor coordination impairments but without speech or reading deficits, which is a surprising omission given the prevalence of theories suggesting a common neural network underlying both functions. We use an emerging imaging technique in cognitive neuroscience; functional transcranial Doppler (fTCD) ultrasound, to assess whether individuals with developmental coordination disorder (DCD) display reduced left‐hemisphere lateralization for speech production compared to control participants. Twelve adult control participants and 12 adults with DCD, but no other developmental/cognitive impairments, performed a word‐generation task whilst undergoing fTCD imaging to establish a hemispheric lateralization index for speech production. All participants also completed an electronic peg‐moving task to determine hand skill. As predicted, the DCD group showed a significantly reduced left lateralization pattern for the speech production task compared to controls. Performance on the motor skill task showed a clear preference for the dominant hand across both groups; however, the DCD group mean movement times were significantly higher for the non‐dominant hand. This is the first study of its kind to assess hand skill and speech lateralization in DCD. The results reveal a reduced leftwards asymmetry for speech and a slower motor performance. This fits alongside previous work showing atypical cerebral lateralization in DCD for other cognitive processes (e.g., executive function and short‐term memory) and thus speaks to debates on theories of the links between motor control and language production.  相似文献

The present study examined whether observers are able to establish multiple attentional sets to concurrently monitor two different spatial locations. Observers identified a target letter in red or cyan among nontarget letters of other heterogeneous colours during a temporal feature search. A peripheral distractor display consisted of one item of either the same colour as the current target, and the other potential target colour, or an irrelevant colour that could never be the target. They identified an odd-ball colour letter among homogenous colours during a singleton search. The results revealed that observers maintained multiple attentional sets for detecting two singletons or for targets involving two (or three) features. However, they were unable to maintain a mixture of sets. Moreover, exposure to a distractor containing feature that corresponded to a feature of the current target was advantageous for target identification. The presence or absence of this set-specific capture depended on top-down knowledge and did not occur automatically in the singleton-detection stream. These results demonstrate a limitation in the flexibility of attentional sets. Although two singleton detections were possible, multiple attentional templates for a more complex attentional set could not be maintained concurrently when monitoring multiple rapid serial visual presentations.  相似文献
