Switching between sensory and affective systems incurs processing costs

Recent models of the conceptual system hold that concepts are grounded in simulations of actual experiences with instances of those concepts in sensory-motor systems (e.g., Barsalou, 1999, 2003; Solomon & Barsalou, 2001). Studies supportive of such a viewhave shown that verifying a property of a concept in one modality, and then switching to verify a property of a different concept in a different modality generates temporal processing costs similar to the cost of switching modalities in perception. In addition to non-emotional concepts, the present experiment investigated switching costs in verifying properties of positive and negative (emotional) concepts. Properties of emotional concepts were taken from vision, audition, and the affective system. Parallel to switching costs in neutral concepts, the study showed that for positive and negative concepts, verifying properties from different modalities produced processing costs such that reaction times were longer and error rates were higher. Importantly, this effect was observed when switching from the affective system to sensory modalities, and vice-versa. These results support the embodied cognition view of emotion in humans.     

Desire for control,perception of control: their impact on autonomous motivation and psychological adjustment

The purpose of the present research was to test the relevance of a theoretical framework based on the matches and the mismatches between desire for control and perception of control (Evans et al. in Br J Psychol 84(2):255–273, 1993), in order to predict autonomous motivation (Deci and Ryan in Intrinsic motivation and self-determination in human behavior. Plenum, New York, 1985, 2012), depression, and anxiety (Bradley in Handbook of psychology and diabetes: A guide to psychological measurement in diabetes research and practice. Harwood Academic Press, Chur, 1994; Bruchon-Schweitzer in Psychologie de la Santé: Modèles, concepts et méthodes. Dunod, Paris, 2002). Two prospective studies were run among undergraduate students. Results of Study 1 confirmed the relevance of Evans et al.’s (in Br J Psychol 84(2):255–273, 1993) theoretical framework. More specifically, four clusters reflecting different levels of desire for control and perception of control were found. Moreover, results revealed that profiles characterized by high scores on both desire for control and perception of control were more autonomously motivated than those characterized by the three other possible combinations. Results of Study 2 replicated those of Study 1 and showed that participants combining a low desire for control and a high perception of control were the less depressed, followed by participants with high scores on both measures. No significant effects were found for anxiety.     

Coping With Vicarious Trauma in the Aftermath of a Natural Disaster

This study documents the vicarious psychological impact of the 2010 earthquake in Haiti on Haitians living in the United States. The role of coping resources—family, religious, and community support—was explored. The results highlight the importance of family and community as coping strategies to manage such trauma. Este estudio documenta el impacto psicológico vicario que tuvo el terremoto de 2010 en Haití sobre los residentes haitianos que viven en Estados Unidos. Se explora el papel de los recursos de afrontamiento—apoyo familiar, religioso y comunitario. Lo resultados destacan la importancia de la familia y la comunidad como estrategias de afrontamiento para superar un trauma de esas características.     

The Influence of Employers' Use of Social Networking Websites in Selection,Online Self‐promotion,and Personality on the Likelihood of Faux Pas Postings

Employers' selection practices sometimes involve reviewing applicants' profile on social networking websites (SNWs) and invading applicants' privacy (e.g., asking for their passwords). Applicants can be eliminated because of faux pas (i.e., inappropriate content) they post online. Yet, little research has examined factors related to faux pas postings. The present study examines employers' use of SNWs in selection, participants' internet and SNWs use, personality, and SNWs self‐promotion as predictors of the likelihood of faux pas postings. Results show lower likelihood of faux pas postings when participants are informed that a high proportion of employers use SNWs in selection, but mainly when it includes invasion of applicants' privacy. Moreover, participants' age, privacy settings, extraversion, and SNWs self‐promotion are related to faux pas.     

Minimal functional brain differences between older adults with and without mild cognitive impairment during the stroop

This investigation compared the neural correlates of inhibition in normal older adults (OAs) and OAs with mild cognitive impairment (MCI). It was hypothesized the MCI group would require a greater amount of resources for inhibition, and therefore display greater functional activation in specific regions of interest (ROIs). Twenty-six OAs without and 17 with MCI completed the Stroop task during functional neuroimaging, and completed additional out-of-scanner neuropsychological measures. During inhibition, there were minimal functional Magnetic Resonance Imaging (fMRI) differences found between groups in a priori specified ROIs and with post-hoc multiple regression analyses. However, these minimal differences did not survive corrected thresholds. Robust differences were found with several tasks of a neuropsychological screening battery. The results of this study suggest only very minimal group differences in fMRI activation during inhibition which may not reliably identify MCI, and this condition may be best detected by traditional neuropsychological techniques.     

Impact of Neurologic Deficits on Motor Imagery: A Systematic Review of Clinical Evaluations

Motor imagery (MI, the mental representation of an action without engaging in its actual execution) is a therapeutically relevant technique to promote motor recovery after neurologic disorders. MI shares common neural and psychological bases with physical practice. Interestingly, both acute and progressive neurologic disorders impact brain motor networks, hence potentially eliciting changes in MI capacities. How experimental neuroscientists and medical practitioners should assess and take into account these changes in order to design fruitful interventions is largely unresolved. Understanding how the psychometric, behavioral and neurophysiological correlates of MI are impacted by neurologic disorders is required. To address this brain-behavior issue, we conducted a systematic review of MI data in stroke, Parkinson’s disease, spinal cord injury, and amputee participants. MI evaluation methods are presented. Redundant MI profiles, primarily based on psychometric and behavioral evaluations, emerged in each clinical population. When present, changes in the psychometric and behavioral correlates of MI were highly congruent with the corresponding motor impairments. Neurophysiological recordings yielded specific changes in cerebral activations during MI, which mirrored structural and functional reorganizations due to neuroplasticity. In this view, MI capacities may not be deteriorated per se by neurologic diseases resulting in chronic motor incapacities, but adjusted to the current state of the motor system. Literature-driven orientations for future clinical research are provided.     

The Equiprobability Bias from a Mathematical and Psychological Perspective

The equiprobability bias (EB) is a tendency to believe that every process in which randomness is involved corresponds to a fair distribution, with equal probabilities for any possible outcome. The EB is known to affect both children and adults, and to increase with probability education. Because it results in probability errors resistant to pedagogical interventions, it has been described as a deep misconception about randomness: the erroneous belief that randomness implies uniformity. In the present paper, we show that the EB is actually not the result of a conceptual error about the definition of randomness. On the contrary, the mathematical theory of randomness does imply uniformity. However, the EB is still a bias, because people tend to assume uniformity even in the case of events that are not random. The pervasiveness of the EB reveals a paradox: The combination of random processes is not necessarily random. The link between the EB and this paradox is discussed, and suggestions are made regarding educational design to overcome difficulties encountered by students as a consequence of the EB.     

Women's hairstyle and men's behavior: A field experiment

Little research has examined the effect of women's hairstyles on people's behavior. In a field study, male and female passersby, walking alone in the street, were observed while walking behind a female‐confederate who dropped a glove and apparently was unaware of her loss. The confederate had long dark hair arranged in three different hairstyles: one with her hair falling naturally on her shoulders and her back, one with her hair tied in a ponytail, and one with her hair twisted in a bun. Results reported that the hairstyle had no effect on female passersby's helping behavior. However, it was found that the hairstyle influenced male passersby with men helping the confederate more readily when her hair fell naturally on her neck, shoulders and upper back.
