Virtual prejudice

According to recent theorizing in social psychology, social behavior is controlled not only by reflective, but also by impulsive systems. The latter are based on associative links that may influence behavior without intent. The current study examined how prejudiced implicit associations affect physiological and automatic behavioral responses. Our native Dutch participants were immersed in a virtual environment in which they encountered virtual persons (avatars) with either White or Moroccan facial features. In line with our predictions, participants maintained more distance and showed an increase in skin conductance level when approaching Moroccan avatars as opposed to White avatars. Participants’ implicit negative associations with Moroccans moderated both effects. Moreover, evidence was found that the relation between implicit prejudice and distance effects was fully mediated by skin conductance level effects. These data demonstrate how prejudiced implicit associations may unintentionally lead to impulsive discriminatory responses.     

A comparison of two methods of assessing representation-mediated food aversions based on shock or illness

In experiments that measured food consumption, Holland (1981; Learning and Motivation, 12, 1-18) found that food aversions were formed when an exteroceptive associate of food was paired with illness, but not when such an associate was paired with shock. By contrast, measuring the ability of food to reinforce instrumental responding, Ward-Robinson and Hall (1999; Quarterly Journal of Experimental Psychology, 52B, 335-350) found that pairing an associatively activated representation of food with shock readily established an aversion to that food. Two experiments considered the origins of these apparently discrepant results. The results did not support either the possibility that instrumental reinforcement power is a more sensitive measure of aversion learning than consumption, or the hypothesis that illness particularly devalues properties of food representations that determine consumption (such as palatability) whereas shock devalues more general properties critical to reinforcement. The results suggested instead that whereas the effects of pairings of a food associate with illness are mediated by changes in the value of the food itself, the effects of pairings with shock are mediated by the conditioning of fear or other competing responses to the site of food delivery, and not by modification of the value of food itself.     

Influence des caractéristiques affectives et sémantiques des exemplaires d’un IAT Jeunes-Vieux sur les mesures d’attitudes résultantes

The IAT is supposed to be a method of indirect measure of the associative strengths between two target concepts (e.g., Young people versus Old) and two attribute concepts (e.g., Good versus Bad). But the stimuli used to represent these concepts can have an influence on IAT effects. We systematically manipulated the affective and semantic features of the stimuli used in a Young-Old IAT. The appearance of target exemplars (photos) and attribute exemplars (words) were perfectly differentiated. Three hundred and twenty subjects participated in the experiment and the results show that IAT effects are both influenced by the stimuli used and by the associative strengths between concepts. Practical and theoretical implications are discussed.

Catastrophic associations predict level of change in anxiety sensitivity in response to cognitive-behavioural treatment for panic

The aim of the present study was to elucidate one of the factors that might be responsible for the maintenance of panic patients' harmful beliefs about anxiety. Specifically, it was hypothesized that harmful beliefs about anxiety, i.e. anxiety sensitivity, is maintained in panic patients by automatic activation of idiographic catastrophic cognitions. To test this prediction, panic patients participated in a one-session cognitive-behavioural treatment of 4-8h to reduce anxiety sensitivity. The strength of automatic catastrophic cognitions in response to idiographic anxiety symptoms, measured with a modified semantic priming task, as well as the strength of the consciously accessible catastrophic meaning of these symptoms were assessed before treatment. In accordance with the hypothesis, stronger automatic catastrophic cognitions predicted a smaller reduction of anxiety sensitivity independently of the strength of conscious catastrophic cognitions. Moreover, in a first exploration, the strength of catastrophic associations was also shown to have an incremental predictive value for change in anxiety sensitivity beyond that of a number of demographic, clinical, treatment and assessment variables. The theoretical and clinical implications are discussed.     

习得性空间联结的迁移依赖于语义工作记忆

采用练习迁移范式与双任务范式相结合的设计来探讨练习所习得的空间联结在工作记忆中如何表征。被试先进行不一致空间的刺激—反应映射练习任务, 五分钟后, 随机迁移到单任务(Simon任务)或者双任务(Simon任务+语义工作记忆负荷任务或空间工作记忆负荷任务)。结果发现：不一致的练习能使单任务出现反转的Simon效应, 但语义工作记忆负荷会使反转的Simon效应消失, 而空间工作记忆负荷却对反转的Simon效应没有影响。实验结果表明练习产生的空间联结依赖于语义工作记忆。     

Aging and prejudice: Diminished regulation of automatic race bias among older adults

A popular view holds that older adults are more prejudiced than younger adults because they grew up in a less tolerant era. An alternative view proposes that aging corresponds with stronger prejudice among older adults because they have reduced capacity to inhibit biased associations that come to mind automatically. To independently assess these possibilities, we modeled the processes underlying implicit racial attitudes in samples of teenagers through people in their nineties. Results indicated that older adults showed greater implicit bias because they were less able to regulate the automatic associations they possessed, not because of holding stronger associations in the first place. These findings suggest that age-related increases in racial biases, even those that are implicit, may be due to self-regulatory failure of older adults, rather than to cohort effects.     

Bias and regulation of bias in intergroup interactions: Implicit attitudes toward Muslims and interaction quality

Previous research suggests that automatically activated bias manifests itself in behavior that can jeopardize the quality of intergroup interactions. However, regulation of automatic associations has the potential to attenuate their influence on intergroup interaction. To test this possibility, 46 non-Muslim White participants interacted with a Muslim confederate and completed an implicit measure of attitudes toward Muslims. The Quadruple Process model [Sherman, J. W., Gawronski, B., Gonsalkorale, K., Hugenberg, K., Allen, T. J., & Groom, C. J. (2008). The self-regulation of automatic associations and behavioral impulses. Psychological Review, 115, 314-335] was applied to the implicit measure to estimate participants’ strength of negative associations with Muslims and their ability to overcome those negative associations. The confederate’s ratings of how much he liked the participants were predicted by an interaction between automatic negative associations and the ability to overcome them. Specifically, when the strength of participants’ negative associations with Muslims was low, participants’ level of overcoming bias was unrelated to the confederate’s ratings. In contrast, the ability to regulate automatic negative associations predicted greater liking when those associations were strong.     

Spatial representations elicit dual-coding effects in mental imagery

Spatial aspects of words are associated with their canonical locations in the real world. Yet little research has tested whether spatial associations denoted in language comprehension generalize to their corresponding images. We directly tested the spatial aspects of mental imagery in picture and word processing (Experiment 1). We also tested whether spatial representations of motion words produce similar perceptual-interference effects as demonstrated by object words (Experiment 2). Findings revealed that words denoting an upward spatial location produced slower responses to targets appearing at the top of the display, whereas words denoting a downward spatial location produced slower responses to targets appearing at the bottom of the display. Perceptual-interference effects did not obtain for pictures or for words lacking a spatial relation. These findings provide greater empirical support for the perceptual-symbols system theory ( Barsalou, 1999, 2008 ).
