Evidence of different developmental trajectories for length estimation according to egocentric and allocentric viewpoints in children and adults

This study investigated the influence of egocentric and allocentric viewpoints on a comparison task of length estimation in children and adults. A total of 100 participants ranging in age from 5 years to adulthood were presented with virtual scenes representing a park landscape with two paths, one straight and one serpentine. Scenes were presented either from an egocentric or allocentric viewpoint. Results showed that when the two paths had the same length, participants always overestimated the length of the straight line for allocentric trials, whereas a development from a systematic overestimation in children to an underestimation of the straight line length in adults was found for egocentric trials. We discuss these findings in terms of the influences of both bias-inhibition processes and school acquisitions.     

Preschoolers’ use of feedback for flexible behavior: Insights from a computational model

This study addressed preschoolers’ cognitive flexibility in an inductive task requiring response feedback processing to infer relevant task goals. A total of 63 4- to 6-year-olds were tested on a perceptual matching task in which they needed to switch attention among three colors. A computational model was designed to track down how responses to positive and negative feedback changed as children progressed through the task. The results showed that children’s differential response to positive and negative feedback developed with age. In addition, age differences in feedback responding increased as the task unfolded. These findings are interpreted as reflecting an increase in flexibility with age in terms of growing efficiency in feedback processing.     

Psychological profiles and emotional regulation characteristics of women engaged in risk-taking sports

We investigated the psychological profiles and emotional regulation characteristics of women involved in risk-taking sports. The research sample (N=180) consisted of three groups of women engaged in: (1) non-risk sports (N=90); (2) risk-taking sports for leisure purposes (N=53); or (3) risk-taking sports as professionals (N=37). Each participant completed five questionnaires, the Sensation Seeking Scale, the Bem Sex Role Inventory, the Barratt Impulsiveness Scale, Risk & Excitement Inventory, and the Toronto Alexithymia Scale. The results revealed significant differences between the groups' profiles. Of particular interest are the differences that exist between the profiles of Group 2 (escape profile, masculine gender identity, and high scores on sensation seeking, impulsivity, alexithymia) and Group 3 (compensation profile, androgynous gender identity, average score on sensation seeking, and low scores on impulsivity, alexithymia). We propose that the professional woman might be considered a model for preventing destructive risk-taking behaviors.     

Task and sex modulate the brain response to emotional incongruity in Asian listeners

In order to recognize banter or sarcasm in social interactions, listeners must integrate verbal and vocal emotional expressions. Here, we investigated event-related potential correlates of this integration in Asian listeners. We presented emotional words spoken with congruous or incongruous emotional prosody. When listeners classified word meaning as positive or negative and ignored prosody, incongruous trials elicited a larger late positivity than congruous trials in women but not in men. Sex differences were absent when listeners evaluated the congruence between word meaning and emotional prosody. The similarity of these results to those obtained in Western listeners suggests that sex differences in emotional speech processing depend on attentional focus and may reflect culturally independent mechanisms.     

Does social dominance generate prejudice? Integrating individual and contextual determinants of intergroup cognitions

Social dominance orientation (SDO) has been proposed as an important variable in the explanation of prejudice. We distinguish between three conceptualizations of SDO: SDO as a personality trait (personality model), SDO as a moderator of the effects of situational variables (Person x Situation model), and SDO as a mediator of the effect of social position on prejudice (group socialization model [GSM]). Four studies (N = 1.657) looking at the relations between social positions, SDO, and prejudice in a natural setting and in a laboratory setting provide strong support for the GSM. In contrast to previous correlational findings, there is evidence of a cause (dominant social position), an effect (prejudice increases), and a mediator (SDO). These results suggest new perspectives on the integration of individual and contextual determinants of prejudice.     

You can detect the trees as well as the forest when adding the leaves: Evidence from visual search tasks containing three-level hierarchical stimuli

The present study investigated how multiple levels of hierarchical stimuli (i.e., global, intermediate and local) are processed during a visual search task. Healthy adults participated in a visual search task in which a target was either present or not at one of the three levels of hierarchical stimuli (global geometrical form made by intermediate forms themselves constituted by local forms). By varying the number of distractors, the results showed that targets presented at global and intermediate levels were detected efficiently (i.e., the detection times did not vary with the number of distractors) whereas local targets were processed less efficiently (i.e., the detection times increased with the number of distractors). Additional experiments confirmed that these results were not due to the size of the target elements or to the spatial proximity among the structural levels. Taken together, these results show that the most local level is always processed less efficiently, suggesting that it is disadvantaged during the competition for attentional resources compared to higher structural levels. The present study thus supports the view that the processing occurring in visual search acts dichotomously rather than continuously. Given that pure structuralist and pure space-based models of attention cannot account for the pattern of our findings, we discuss the implication for perception, attentional selection and executive control of target position on hierarchical stimuli.     

Foot-in-the-door and door-in-the-face: a comparative meta-analytic study

The so-called foot-in-the-door and door-in-the-face techniques have been generally considered as procedures which may consistently influence others' behavior. This study compared efficiency (in terms of compliance rates with various target requests) of both techniques using meta-analysis. It is based on the accumulated studies directly comparing foot-in-the-door (n=22, subjects= 1581) and door-in-the-face (n=22, subjects= 1611) under a similar target request. Analysis indicated no significant differences in efficiency between the paradigms.     

Players’ Gender and Male Referees’ Decisions About Aggression in French Soccer: A Preliminary Study

The aim of this study was to examine (a) aggression displayed by players and (b) referees decisions about these behaviors as a function of the gender of the players in French soccer. Twenty-six games (13 for women and 13 for men) were videotaped. Instrumental aggressive acts and referees decisions were then observed. The findings indicated a significant effect of gender on instrumental aggression and referees decisions related to these behaviors. Male players displayed more instrumental aggressive acts than female players did. Nevertheless, relative to the total number of aggressive acts displayed, referees penalized women more than men. Gender stereotypes might be a relevant explanation for these results, as soccer is generally perceived as a masculine-type sport, particularly in France, and aggression as a masculine characteristic.
