Incongruent object/context relationships in visual scenes: Where are they processed in the brain?

Rapid object visual categorization in briefly flashed natural scenes is influenced by the surrounding context. The neural correlates underlying reduced categorization performance in response to incongruent object/context associations remain unclear and were investigated in the present study using fMRI. Participants were instructed to categorize objects in briefly presented scenes (exposure duration = 100 ms). Half of the scenes consisted of objects pasted in an expected (congruent) context, whereas for the other half, objects were embedded in incongruent contexts. Object categorization was more accurate and faster in congruent relative to incongruent scenes. Moreover, we found that the two types of scenes elicited different patterns of cerebral activation. In particular, the processing of incongruent scenes induced increased activations in the parahippocampal cortex, as well as in the right frontal cortex. This higher activity may indicate additional neural processing of the novel (non experienced) contextual associations that were inherent to the incongruent scenes. Moreover, our results suggest that the locus of object categorization impairment due to contextual incongruence is in the right anterior parahippocampal cortex. Indeed in this region activity was correlated with the reaction time increase observed with incongruent scenes. Representations for associations between objects and their usual context of appearance might be encoded in the right anterior parahippocampal cortex.     

Self‐determination theory,social media and charitable causes: An in‐depth analysis of autonomous motivation

Using the framework of the self‐determination theory continuum, we investigated the influence of the distinct autonomous and controlled motivational regulations for engaging participants in online and offline support of charitable events for the causes of breast cancer and homeless youth. Participants were exposed online to Facebook event pages appealing to helping others. When the often omitted integrated autonomous regulation was included in the model, it was the strongest predictor of supportive intentions. Without integrated regulation in the model, we would have overestimated the relatively minor influence of controlled introjected regulation. Furthermore, rather than one overall measure of autonomous intrinsic regulation, we assessed the differential influences of three separate dimensions (to experience stimulation, to learn and to accomplish). Intrinsic motivation to experience stimulation had a unique influence on online and offline supportive intentions. Such was not the case for the dimensions of to learn or to accomplish. Follow‐up meditation analyses of self‐reported behaviours confirmed that autonomous integrated and intrinsic to experience stimulation regulations led to stronger intentions to support online behaviours, which, in turn, increased the likelihood of actual online engagement. The findings in a social media context highlight the importance of analysing distinct regulatory styles within the self‐determination theory continuum. Copyright © 2015 John Wiley & Sons, Ltd.     

Personality Predicts Obedience in a Milgram Paradigm

This study investigates how obedience in a Milgram‐like experiment is predicted by interindividual differences. Participants were 35 males and 31 females aged 26–54 from the general population who were contacted by phone 8 months after their participation in a study transposing Milgram's obedience paradigm to the context of a fake television game show. Interviews were presented as opinion polls with no stated ties to the earlier experiment. Personality was assessed by the Big Five Mini‐Markers questionnaire (Saucier, 1994). Political orientation and social activism were also measured. Results confirmed hypotheses that Conscientiousness and Agreeableness would be associated with willingness to administer higher‐intensity electric shocks to a victim. Political orientation and social activism were also related to obedience. Our results provide empirical evidence suggesting that individual differences in personality and political variables matter in the explanation of obedience to authority.     

Testing the subtractive pattern of cultural identification

Identity integration, and more specifically, the subtractive pattern of cultural identification, is investigated in this article. This pattern is hypothesized to occur when individuals integrate a new group identity of higher and legitimate status than their original identity, resulting in lower identification with the original group. The first study examined how relative status predicts the subtractive pattern of identification in immigrants living in Canada. Studies 2 and 3—conducted among Kyrgyz and Canadian participants—extended these results by measuring the impact of legitimacy on the subtractive pattern of identification. Results support the hypothesis that the subtractive pattern of identification takes place when the new identity has a higher and legitimate status compared with the original one, highlighting the possible different patterns of identity integration.     

“I’m not the same person since I met you”: The role of romantic passion in how people change when they get involved in a romantic relationship

Using the dualistic perspective on romantic passion (Ratelle et al. in Motiv Emot 37:106–120, 2013; Vallerand et al. in J Pers Soc Psychol 85:756–767, 2003), the present research examined the role of harmonious and obsessive romantic passion in the prediction of personal changes in people’s lives associated with romantic relationships. Young adults recruited through universities (Studies 1 and 2) and social networking sites (Studies 2 and 3) composed the samples of the three studies. Results of Study 1 revealed that harmonious and obsessive passion both positively predicted perceptions of personal growth while they respectively negatively and positively predicted disengagement from important activities and other social relationships for the sake of the romantic relationship. These associations were either fully replicated (for harmonious passion) or partially replicated (for obsessive passion) when examined using a six-month longitudinal design (Study 2) and when the two outcomes (i.e., personal growth and social disengagement) were reported by an informant (Study 3). Overall, the results suggest that the nature and extent of changes in people’s lives as they become romantically involved may be predicted by the quality of their romantic passion.
