Even at subclinical levels, anxiety and depression are associated with impaired cognitive control. It is unclear, though, to what extent these deficits reflect a common underlying dysfunction. Using a non-affective hybrid masked prime-Simon task, we obtained several measures of within- and between- trial inhibitory behavioral control in 80 young, healthy volunteers, together with measures of their anxiety and depression levels. Neither depression nor anxiety affected low-level within-trial control, or any of the between-trial control measures. However, increased levels of depression, but not of anxiety, were associated with impaired high-level within-trial control (increased Simon effect). Results indicate that depression, but not anxiety, impairs voluntary online response-control mechanisms independent of affective content. 相似文献

Face and symmetry processing have common characteristics, and several lines of evidence suggest they interact. To characterize their relationship and possible interactions, in the present study we created a novel library of images in which symmetry and face-likeness were manipulated independently. Participants identified the target that was most symmetric among distractors of equal face-likeness (Experiment 1) and identified the target that was most face-like among distractors of equal symmetry (Experiment 2). In Experiment 1, we found that symmetry judgments improved when the stimuli were more face-like. In Experiment 2, we found a more complex interaction: Image symmetry had no effect on detecting frontally viewed faces, but worsened performance for nonfrontally viewed faces. There was no difference in performance for upright versus inverted images, suggesting that these interactions occurred on the parts-based level. In sum, when symmetry and face-likeness are independently manipulated, we find that each influences the perception of the other, but the nature of the interactions differs. 相似文献

Efforts to discourage excessive alcohol use among young people can only be effective if the target audience is exposed to, attends to, and comprehends key messages. The aim of this study was to examine age and sex differences in drinking motives to better inform development of targeted interventions to reduce alcohol-related harm. Thirty individual interviews and 12 group interviews were conducted with English 13–25?year olds. Interviewees gave multiple motivations for drinking – especially those related to image and reputation, and played down the health implications of heavy drinking. Negative aspects of drinking – caring for drunk friends, being cared for when drunk and suffering through hangovers with friends – were considered to offer opportunities for closer interpersonal bonding than other social activities. Respondents distanced themselves from ‘problem’ drinkers, but disapproved of others’ problematic drinking or antisocial behaviour. Narrative messages demonstrating the social consequences of excessive consumption were preferred to single, static messages emphasising risk or harm. Interviewees noted that interventions must use an engaging tone or pitch: they considered many campaigns to be patronising or preaching. A lack of consensus between age and sex groups highlighted a need for multifaceted, multi-modal approaches that utilise mobile technologies and new media. 相似文献

Research has shown that strength of handedness – a proxy variable for the degree of interaction between the left and right brain hemispheres – predicts differences in a variety of cognitive domains. The present paper extends this work to message (or goal) framing effects in which persuasive health communications emphasise positive vs. negative outcomes. One hundred fifty-six participants read pamphlets containing statements emphasising either the gains of using or the losses of not using sunscreen. Replicating previous research, non-users of sunscreen were more affected by framed messages than users. However, we found a loss- rather than gain-framed advantage, and mixed (inconsistent)-handers seemed to drive these effects more so than strong (consistent)-handers. These results suggest that a ‘one-size-fits-all’ approach may be inadequate in crafting effective educational messages about health behaviours, and that theories centring around one’s regulatory focus orientation as well as new methods in laterality research may be useful in reaching the widest range of individuals. 相似文献

Trait self-control is related to a number of positive outcomes, including mental health, interpersonal success, academic success and health-related behaviours. This study sought to explore the relationships between self-control, reports of mental and physical health symptoms and coping styles. The results revealed that higher self-control was related to fewer mental and physical health symptoms and less avoidance coping. There was not a significant relationship between self-control and problem-focused or emotion-focused coping styles. Further, the relationships between self-control and mental and physical health outcomes were partially mediated by avoidance coping style. Specifically, the data suggest lower self-control is associated with unhealthy coping strategies (avoidance coping), which in turn are associated with worse mental health outcomes and greater reports of physical health symptoms. Thus lower trait self-control can serve as an indicator, suggesting circumstances in which individuals’ tendencies to engage in unhealthy coping strategies are increased. These findings add to a growing body of literature underscoring the importance of trait self-control. 相似文献

Abstract In personal construct theory, people interpret the world in unique ways. Constructions are subjective representations rather than objective truths. This means that our ethical constructions are (a) potentially wrong, if there is an external moral reality we cannot access, or (b) no more inherently defensible than others’ ethical constructions, if all notions of “right” and “wrong” are personally constructed. Constructions promoting violence, hatred, and intolerance are as viable as those promoting peace, love, and acceptance. To overcome this ethical quandary individuals must create meaningful ethical constructions and have faith in them. This is difficult because, as constructivists, we see each person's constructions as legitimate and our own world views as merely constructions, themselves. Implications for moral righteousness are discussed. 相似文献

Fear of death features in both historical and contemporary theories of religion, but the relationship between death anxiety and religious belief is still ambiguous, largely due to the use of inappropriate or imprecise measures. The current studies therefore aimed to develop a valid, targeted measure of respondents' tendency towards religious belief, the ‘Supernatural Belief Scale’ (SBS), and to use the SBS to examine the relation between death anxiety and religious belief. Results indicate that the SBS shows high reliability and convergent validity and that its relation to death anxiety depends on participants' religious identification: ‘religious’ participants fear death less the stronger their religious beliefs, whereas ‘non‐religious’ participants are more inclined towards religious belief the more they fear death. These studies contribute a new measurement tool for research on religious belief and provide a starting point for an experimental integration of discrepant research findings.

Incorporated in a simulator design project, this study assessed the utility of a simulator prototype for air combat training to optimize continued development. After several scenarios, the 13 male participants completed a survey. Seven fidelity levels: visual feedback, head-up/head-down, instrumentation, flight controls, graphics, visual resolution, and field-of-view were rated for three dimensions: realism, limitation of performance, and importance of realism. The results informed decisions about which fidelity levels, head-up/head-down and field-of-view, that should be prioritized during the next design cycle, and generated recommendations for continued simulator design and directives for further evaluations. 相似文献

An effective Hamiltonian for the two-band Hubbard model was derived by a canonical transformation which was calculated and summed up to infinite order . The transformed Hamiltonian contains terms with strongly renormalized interaction energies. These new interaction energies show sign reversals as a function of the hopping integral in addition to a strong reduction in the charge-transfer gap and a significant increase in the attractive oxygen Hubbard term. 相似文献

The kinetics for the termination migration of a rod-type alpha particle in a two-phase Ti alloy was predicted on the basis of the edge recession theory. The developed model quantified the effect of geometrical dimensions and diffusional factors on the spheroidization rate. Comparison with the experimental results of Ti–6Al–4Fe showed that the model can provide a reasonable prediction of the time to complete the static spheroidization of rod-type particles. 相似文献
