Objectives: This study examined the effects of negative aging stereotypes on self-reported loneliness, risk-taking, subjective health, and help-seeking behavior in a French sample of older adults. The aim of this study was to show the detrimental effects of negative aging stereotypes on older adults’ self-evaluations and behaviors, therefore contributing to the explanations of the iatrogenic effect of social environments that increase dependency (e.g., health care institutions). Method: In the first experiment conducted on 57 older adults, we explored the effects of positive, neutral, or negative stereotype activation on the feeling of loneliness and risk taking decision. The second experiment (n = 60) examined the impact of stereotype activation on subjective health, self-reported extraversion as well as on a genuine help-seeking behavior, by allowing participants to ask for the experimenters help while completing a task. Results: As predicted, negative stereotype activation resulted in lower levels of risk taking, subjective health and extraversion, and in higher feelings of loneliness and a more frequent help-seeking behavior. Conclusion: These findings suggest that the mere activation of negative stereotypes can have broad and deleterious effects on older individuals’ self-evaluation and functioning, which in turn may contribute to the often observed dependency among older people.

Newly measured rating norms provide a database of emotion-related dimensions for 524 French trait words. Measures include valence, approach/avoidance tendencies associated with the trait, possessor- and other-relevance of the trait, and discrete emotions conveyed by the trait (i.e., anger, disgust, fear, happiness, and sadness). The normative data were obtained from 328 participants and were revealed to be stable across samples and gender. These data go beyond a dimensional structure and consider more fine-grained descriptions such as the categorical emotions, as well as the perspective of the evaluator conveyed by the traits. They should thus be particularly useful for researchers interested in emotion or in the emotional dimension of cognition, action, or personality. The database is available as supplementary material.

Abstract Although perceived attractiveness has consistently been shown to influence interpersonal attraction, perceiving another person as more similar to oneself is also highly important for attraction. We examine how both perceptions impact unilateral initial attraction (UIA), defined as a positive reaction following the perception of an unknown target within minimal information settings. In three studies, we examine this phenomenon in a social networking site scenario, by asking participants to imagine they were browsing such a site. In Study 1, participants reported greater UIA for an attractive target, and this effect was partially mediated by perceived similarity. In Study 2, participants reported greater UIA for a target neutral in attractiveness, after being conceptually primed with similarity. This effect was mediated by perceived attractiveness. In Study 3, both perceived similarity and perceived attractiveness were associated with increases in UIA, which in turn was associated with greater interest to interact with a target neutral in attractiveness. These novel findings show the importance of perceived similarity for UIA and the importance of this phenomenon for online interactions. We conclude by discussing general implications for online social activities, specifically relationship development.

ABSTRACT Previous studies suggest that ancient (i.e. evolutionary-based) threats capture attention because human beings possess an inborn module shaped by evolution and dedicated to their detection. An alternative account proposes that a key feature predicting whether a stimulus will capture attention is its relevance rather than its ontology (i.e. phylogenetic or ontogenetic threat). Within this framework, the present research deals with the attentional capture by threats commonly encountered in our urban environment. In two experiments, we investigate the attentional capture by modern threats (i.e. weapons). In Experiment 1, participants responded to a target preceded by a cue, which was a weapon or a non-threatening stimulus. We found a larger cuing effect (faster reaction times to valid vs. invalid trials) with weapons as compared with non-threatening cues. In Experiment 2, modern (e.g. weapons) and ancient threats (e.g. snakes) were pitted against one another as cues to determine which ones preferentially capture attention. Crucially, participants were faster to detect a target preceded by a modern as opposed to an ancient threat, providing initial evidence for a superiority of modern threat. Overall, the present findings appear more consistent with a relevance-based explanation rather than an evolutionary-based explanation of threat detection.

ABSTRACT A growing body of research challenges the automaticity of evaluative priming (EP). The present research adds to this literature by suggesting that EP is sensitive to processing styles. We relied on previous research showing that EP is determined by the extent to which the prime and the target events on a given trial are processed as a unified compound. Here, we further hypothesised that processing styles encouraging the inclusion of the prime to the target episode support congruity effects, whereas processing styles that enhance the exclusion of the prime from the target episode interrupt (or reverse) these effects. In Experiment 1, a preceding similarity search task produced a congruity effect, whereas a dissimilarity search task eliminated and (non-significantly) reversed this effect. In Experiments 2 and 3, we replicated and extended these findings using a global/local processing manipulation. Overall, these findings confirm that EP is flexible, open to top-down influences and strategic regulation.

In evaluative priming, positive or negative primes facilitate reactions to targets that share the same valence. While this effect is commonly explained as reflecting invariant structures in semantic long-term memory or in the sensorimotor system, the present research highlights the role of integrativity in evaluative priming. Integrativity refers to the ease of integrating two concepts into a new meaningful compound representation. In extended material tests using paired comparisons from two pools of positive and negative words, we show that evaluative congruity is highly correlated with integrativity. Therefore, in most priming studies, congruity and integrativity are strongly confounded. When both aspects are disentangled by manipulating congruity and integrativity orthogonally, three priming experiments show that evaluative-priming effects were confined to integrative prime-target pairs. No facilitation of prime-congruent targets was obtained for non-integrative stimuli. These findings are discussed from a broader perspective on priming conceived as flexible, context-dependent, and serving a generative adaptation function.
