道路交通标志中对称结构效应的眼动研究

本研究考察了道路交通标志中路名信息对称结构效应的眼动模式。实验采用眼动跟踪技术和视觉搜索范式,共有16名被试参加。实验结果表明：（1）在对称结构路名信息的视觉搜索中,被试的反应正确率明显优于非对称结构条件下的正确率;（2）对称结构条件下,被试的注视点和回扫次数明显较少,凝视时间明显较短;（3）在以道路交通标志为视觉搜索材料时,搜索区有无路名目标对视觉搜索绩效没有影响。可以认为：在道路交通标志中存在对称结构效应;眼动模式的差异是引起对称结构效应的认知机制。     

To speak in tongues: language,diversity and psychoanalysis

After reviewing the different psychoanalytical approaches to language of authors such as Freud, Lacan, Kristeva, Jung and Nicolas Abraham, the author examines the problem of 'analytical listening', of the attitude that every analyst must assume towards the words of the analysand, words that must be heard not just in terms of their content but above all in terms of their sound. We live in a culture in which visual images predominate over acoustic images and all too often this cultural trend is repeated in analysis, but it is only when we can hear the 'poetry' of the analysand's discourse that we are able to provide an 'echo', an analytical response that can co-symbolize with, that can offer to the analysand a word or a metaphor that will unlock the symbol hidden behind his or her words. The author then turns to the problem of bilinguism and its role in analysis. In her view, bilingual analysts are facilitated in their task of listening and of translation, because bilinguism facilitates the rapidity and fluidity of the analyst's associations, and at the same time sharpens his or her awareness of how the sound of a word can subtly change its meaning. The paper ends with a clinical vignette which illustrates the role that language can play in hysteria. In hysteria the dissociation between body and psyche is accompanied by a dissociation inside language itself, between verbalization and vocalization. These dissociations can be linked to the traumatic impact of the encounter between the 'language of tenderness' and the 'language of passion', between the child's attachment needs and parental sexuality. In such cases the failure of communication can be resolved principally through the use the analyst makes of the countertransference.     

The effect of message framing and the nature of the targeted illness on individuals’ intention to participate in clinical trials

IntroductionClinical trials are considered as the most useful methods to evaluate the efficacy of new medical treatments, but the participation of healthy individuals is often too small, which limits the statistical power of the trial and hence its effectiveness.ObjectiveThe goal of the present research is to assess, for the first time, the effects of message framing (gain versus loss) and of the nature of the illness targeted by a clinical trial (highly- versus mildly-contagious) on individuals’ intention to enter it.MethodsThe experimental manipulation is carried out within a scenario promoting a clinical trial, in a 2 (framing: gain vs loss) × 2 (nature of the illness: highly- vs mildly-contagious) between-participants design. After reading the scenario, participants were asked to rate their intention to enter the trial and their perception of its utility.ResultsStatistical analyses validated a causal model explaining that a gain-framed message describing a highly-contagious illness increases the perception of the utility of the clinical trial, which in turn enhances the intention to participate.ConclusionThe discussion mainly focuses on the contributions of these findings at a theoretical level, considering the limits and potential of their possible application.     

The Influence of Skills,Message Frame,and Visual Aids on Prevention of Sexually Transmitted Diseases

In a large three week longitudinal study, we investigated the efficacy of framed messages for promoting condom use in sexually active young adults. We also investigated the influence of key risk literacy skills (i.e., numeracy and graph literacy) and visual aids (i.e., icon arrays) on the efficacy of framed messages. Finally, we investigated the underlying psychological mechanisms of behavioral change on the ability of icon arrays to improve message effectiveness. Results showed that framed messages including icon arrays increased adherence to self‐reported condom use by giving rise to enduring changes in attitudes and behavioral intentions, which influenced behavior. Icon arrays were found to be most beneficial among young adults with relatively low numeracy as long as they had high graph literacy. These findings build on the previous research in risk communication and extend psychological theories of health‐related decision making such as the theory of planned behavior. These findings also map the conditions under which well‐constructed visual aids can be among the most effective, transparent, and ethically desirable means of risk communication. Implications for risk communication and informed medical decision making are discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

When the death makes you smoke: A terror management perspective on the effectiveness of cigarette on-pack warnings

One of the principal vehicles for informing tobacco consumers about the risks of smoking is the warning message on each cigarette package. Based on terror management theory, the present study investigates the impact of mortality-salient warnings on cigarette packages compared to warnings with no mortality threat. Results suggest that to the degree that smoking is a source of self-esteem, later attitudes towards smoking become more positive if the warning message is mortality-salient. On the contrary, if the warning is terrifying but not mortality-salient and relates to the source of self-esteem, smoking attitudes become more negative with higher smoking-based self-esteem. Thus, mortality-salient warnings may increase the tendency to favor smoking under certain circumstances. This fatal ironic effect highlights the importance of a risk communication that matches the self-esteem contingencies of the recipients, and it has urgent implications for health care policy.     

Emerging School Refusal: A School-Based Framework for Identifying Early Signs and Risk Factors

A student’s academic and social-emotional development is increasingly jeopardized with mounting absence from school. School refusal (SR) is one type of school attendance problem (SAP) that is often associated with absence from school. Once established, it can sometimes be difficult to treat. To prevent established SR and associated problems, indicators of emerging SR and risk for SR should be efficiently identified and acted upon. Risk factors are often discussed in relation to SAPs generally rather than considering risk for specific types of attendance problems. Based on literature review, this paper provides an account of the likely signs and risks for emerging SR. A school-based framework is provided to support school personnel and parents in working together to identify these signs and risks. Several challenges associated with the implementation of the framework are discussed.     

Does integral affect influence intentions to use artificial intelligence for skin cancer screening? A test of the affect heuristic

Objective: This study investigated how affect influences people’s processing of messages about risks and benefits of using autonomous artificial intelligence (AI) technology to screen for skin cancer. We examined integral affect (emotion derived during decision making) separately from incidental affect (extraneous mood states).

Design: Using the affect heuristic framework, we randomly assigned 273 participants to conditions featuring risk (high, low, uncertain) or benefit (high, low, uncertain) messages about AI. Following ‘affect-as-spotlight’, we also explored whether people’s integral affect towards skin cancer moderated the relationship between risk/benefit messages and AI screening intentions.

Outcomes: Perceived risk, perceived benefit, positive and negative affect toward AI, intention to use AI screening.

Results: After controlling for incidental affect and risk perceptions, we found that compared to low risk messages, uncertain risk messages increased participants’ negative affect toward AI, decreased positive affect toward AI, increased AI risk evaluations and reduced AI benefit evaluations. Perceptual variables significantly mediated participants’ intentions to use AI for risk messages but not benefit messages. No moderation effects were found.

Conclusions: Results suggest extending the affect heuristic framework to include uncertain risk conditions. Integral AI affect influenced people’s interpretation of messages, which then impacted likelihood to use AI technology for health.     

Affinity propagation: An exemplar-based tool for clustering in psychological research

Affinity propagation is a message-passing-based clustering procedure that has received widespread attention in domains such as biological science, physics, and computer science. However, its implementation in psychology and related areas of social science is comparatively scant. In this paper, we describe the basic principles of affinity propagation, its relationship to other clustering problems, and the types of data for which it can be used for cluster analysis. More importantly, we identify the strengths and weaknesses of affinity propagation as a clustering tool in general and highlight potential opportunities for its use in psychological research. Numerical examples are provided to illustrate the method.     

How do we optimize message matching interventions? Identifying matching thresholds,and simultaneously matching to multiple characteristics

Matching the content of persuasive messages to the characteristics (e.g., motives, personality) of people receiving them is a widely used technique to improve persuasion. However, little is known about how to optimize matching beyond simply using the technique. We propose that matching interventions can be strengthened by matching messages to multiple characteristics at a time, and introduce the concept of matching thresholds to improve the way interventionists assign messages. Matching thresholds are defined as the points along characteristics where people change from being most responsive to one message type to another. We provide statistical and methodological tools to estimate matching thresholds, and evaluate these tools in two simulation studies. We then report an online experiment (N = 568) where we find an advantage for simultaneously matching messages to two characteristics (promotion focus and interdependent self-construal) and provide estimates of the matching thresholds to guide the assignment of gain/loss frames and independence/interdependence appeals.
