The study investigated attentional biases for pictorial and linguistic health-threat stimuli in high and low health anxious individuals, who were selected from the upper and lower quartile ranges of a normal sample using a screening measure of health anxiety. Attentional bias was assessed using a visual probe task which presented health-threat and neutral pictures and words at two exposure durations, 500 ms and 1250 ms. The prediction that the high health anxious group would show a greater attentional bias for health-threat cues than the low health anxious group was not supported despite the groups being well-differentiated on a general measure of health anxiety, the Illness Attitudes Scale (IAS). Instead, the results indicated that individuals with high levels of anxiety sensitivity showed a significantly greater initial attentional bias for threat pictures compared with those with low anxiety sensitivity, as assessed by the Anxiety Sensitivity Index (ASI).  相似文献

Pointing to novel links between mental representation and social communication, we examine the association between vividness of imagery and use of metaphors. In a study on individual differences and three experiments, we demonstrate that vivid imagery is linked to greater use of metaphors and that this relationship is bi-directional. We also show that this relationship is stronger in the context of negative valence. We demonstrate that vivid imagery results in greater generation of metaphors (in particular, for negative concepts). In examining the reverse direction of influence, we show that in the negative (rather than positive) context, use of metaphors results in greater perceptions of vividness. We suggest that vividness can be signified and produced by using metaphors that play an important role in meaning making and communication.  相似文献

It has been proposed that angry people exhibit optimistic risk estimates about future events and, consequently, are biased towards making risk-seeking choices. The goal of this study was to directly test the hypothesised effect of trait anger on optimism and risk-taking behaviour. One hundred healthy volunteers completed questionnaires about personality traits, optimism and risk behaviour. In addition their risk tendency was assessed with the Balloon Analogue Risk Task (BART), which provides an online measure of risk behaviour. Our results partly confirmed the relation between trait anger and outcome expectations of future life events, but suggest that this optimism does not necessarily translate into actual risk-seeking behaviour.  相似文献

One individual difference that is conceptually closely related to the positive and negative framing of outcomes in persuasive communications is the person's self-discrepancy. It was expected that a match between a person's self-discrepancy and framing will lead to more persuasion, under the condition that the information is processed centrally (high involvement). Two experiments were conducted to test this expectation, one through the Internet among obese people and one in the laboratory among students. Both experiments showed that only among those with high involvement—assessed as an individual difference—participants with an ideal-discrepancy were persuaded the most by the positively framed information, whereas participants with an ought-discrepancy were persuaded the most by the negatively framed information.  相似文献

The study investigated attentional biases for pictorial and linguistic health‐threat stimuli in high and low health anxious individuals, who were selected from the upper and lower quartile ranges of a normal sample using a screening measure of health anxiety. Attentional bias was assessed using a visual probe task which presented health‐threat and neutral pictures and words at two exposure durations, 500 ms and 1250 ms. The prediction that the high health anxious group would show a greater attentional bias for health‐threat cues than the low health anxious group was not supported despite the groups being well‐differentiated on a general measure of health anxiety, the Illness Attitudes Scale (IAS). Instead, the results indicated that individuals with high levels of anxiety sensitivity showed a significantly greater initial attentional bias for threat pictures compared with those with low anxiety sensitivity, as assessed by the Anxiety Sensitivity Index (ASI).  相似文献

The present behavioral study aimed to examine the impact of language control expertise on two domain-general control processes, i.e. active inhibition of competing representations and overcoming of inhibition. We compared how Simultaneous Interpreters (SI) and Highly Proficient Bilinguals—two groups assumed to differ in language control capacity—performed executive tasks involving specific inhibition processes. In Experiment 1 (language decision task), both active and overcoming of inhibition processes are involved, while in Experiment 2 (bilingual Stroop task) only interference suppression is supposed to be required. The results of Experiment 1 showed a language switching effect only for the highly proficient bilinguals, potentially because overcoming of inhibition requires more cognitive resources than in SI. Nevertheless, both groups performed similarly on the Stroop task in Experiment 2, which suggests that active inhibition may work similarly in both groups. These contrasting results suggest that overcoming of inhibition may be harder to master than active inhibition. Taken together, these data indicate that some executive control processes may be less sensitive to the degree of expertise in bilingual language control than others. Our findings lend support to psycholinguistic models of bilingualism postulating a higher-order mechanism regulating language activation.  相似文献

The aim of the present study was to investigate whether attachment insecurity, focusing on disorganized attachment, and the executive function (EF) component of inhibition, assessed at age 5, were longitudinally related to general externalizing problem behaviors as well as to specific symptoms of ADHD and Autism spectrum disorder (ASD), and callous-unemotional (CU) traits. General externalizing problem behaviors were also measured at age 5 to allow for a developmental analysis. Outcome variables were rated by parents and teachers. The sample consisted of 65 children with an oversampling of children with high levels of externalizing behaviors. Attachment was evaluated using a story stem attachment doll play procedure. Inhibition was measured using four different tasks. The results showed that both disorganized attachment and poor inhibition were longitudinally related to all outcome variables. Controlling for initial level of externalizing problem behavior, poor inhibition predicted ADHD symptoms and externalizing problem behaviors, independent of disorganized attachment, whereas for ASD symptoms no predictive relations remained. Disorganized attachment independently predicted CU traits.  相似文献

Significant efforts have been made to define ethical responsibilities for professionals engaged in nanotechnology innovation. Rosalyn Berne delineated three ethical dimensions of nanotechnological innovation: non-negotiable concerns, negotiable socio-cultural claims, and tacitly ingrained norms. Braden Allenby demarcated three levels of responsibility: the individual, professional societies (e.g. engineering codes), and the macro-ethical. This article will explore how these definitions of responsibility map onto practitioners’ understanding of their responsibilities and the responsibilities of others using the nanotechnology innovation community of the greater Phoenix area, which includes academic researchers, investors, entrepreneurs, manufacturers, insurers, attorneys, buyers, and media. To do this we develop a three-by-three matrix that combines Berne’s three dimensions and Allenby’s three levels. We then categorize the ethical responsibilities expressed by forty-five practitioners in semi-structured interviews using these published dimensions and levels. Two questions guide the research: (i) what responsibilities do actors express as theirs and/or assign to other actors and; (ii) can those responsibilities be mapped to the presented ethical frameworks? We found that most of the responsibilities outlined by our respondents concentrate at the professional society + non-negotiable and professional + negotiable intersections. The study moves from a philosophical exploration of ethics to an empirical analysis, exploring strengths, weaknesses, and gaps in the existing nanotechnology innovation network. This opens the door for new practitioners to be introduced in an effort to address responsibilities that are not currently recognized.  相似文献
