Mirror Neuron System and Mentalizing System connect during online social interaction

Two sets of brain areas are repeatedly reported in neuroimaging studies on social cognition: the Mirror Neuron System and the Mentalizing System. The Mirror System is involved in goal understanding and has been associated with several emotional and cognitive functions central to social interaction, ranging from empathy to gestural communication and imitation. The Mentalizing System is recruited in tasks requiring cognitive processes such as self-reference and understanding of other’s intentions. Although theoretical accounts for an interaction between the two systems have been proposed, little is known about their synergy during social exchanges. In order to explore this question, we have recorded brain activity by means of functional MRI during live social exchanges based on reciprocal imitation of hand gestures. Here, we investigate, using the method of psychophysiological interaction, the changes in functional connectivity of the Mirror System due to the conditions of interest (being imitated, imitating) compared with passive observation of hand gestures. We report a strong coupling between the Mirror System and the Mentalizing System during the imitative exchanges. Our findings suggest a complementary role of the two networks during social encounters. The Mirror System would engage in the preparation of own actions and the simulation of other’s actions, while the Mentalizing System would engage in the anticipation of the other’s intention and thus would participate to the co-regulation of reciprocal actions. Beyond a specific effect of imitation, the design used offers the opportunity to tackle the role of role-switching in an interpersonal account of social cognition.     

Impaired configural body processing in anorexia nervosa: Evidence from the body inversion effect

Patients with anorexia nervosa (AN) suffer from severe disturbances of body perception. It is unclear, however, whether such disturbances are linked to specific alterations in the processing of body configurations with respect to the local processing of body part details. Here, we compared a consecutive sample of 12 AN patients with a group of 12 age‐, gender‐ and education‐matched controls using an inversion effect paradigm requiring the visual discrimination of upright and inverted pictures of whole bodies, faces and objects. The AN patients presented selective deficits in the discrimination of upright body stimuli, which requires configural processing. Conversely, patients and controls showed comparable abilities in the discrimination of inverted bodies, which involves only detail‐based processing, and in the discrimination of both upright and inverted faces and objects. Importantly, the body inversion effect negatively correlated with the persistence scores at the Temperament and Character Inventory, which evaluates increased tendency to convert a signal of punishment into a signal of reinforcement. These results suggest that the deficits of configural processing in AN patients may be associated with their obsessive worries about body appearance and to the excessive attention to details that characterizes their general perceptual style.     

Effects of Personalized Versus Generic Implementation of an Intra-Organizational Online Survey on Psychological Anonymity and Response Behavior: A Field Experiment

Purpose

In the present study, we sought to investigate the effects of online survey implementation strategies on perceived anonymity and employee response behavior in organizational surveys.

Design/Methodology/Approach

A field experiment was conducted to compare two commonly used online survey implementation strategies (N = 815). One group of employees received a personalized invitation to the survey and a log-in password, while the other group received a general invitation and did not have to provide a password.

Findings

The results showed that the applied implementation strategies had no substantial effects on perceived anonymity. Moreover, there were no significant effects on nonresponse or the responses of survey participants to closed-ended and open-ended survey questions.

Implications

The present study supposes that online surveys are not a uniform phenomenon and that differences in the implementation of online surveys need to be considered. However, the findings indicate that the use of specified-personalized implementation strategies does not necessarily lead to a substantial decrease in perceived anonymity or automatically result in reduced data quality. Thus, in many cases, the investigated online survey implementation strategies are unlikely to cause serious reductions in perceptions of anonymity and quality of responses to organizational online surveys.

Originality/Value

In spite of the frequent use of online surveys in organizations, little is known about the consequences of online implementation strategies for perceptions of anonymity and response behavior. This study is one of the few empirical examinations of the psychological consequences of different online implementation strategies frequently used in organizational surveying.     

“Ashes to Ashes…”: Could the Recent Evolution of the Cremation Practice in Italy be Interpreted as an Indication of Secularisation?

In the second half of the nineteenth century, a massive communication campaign sustaining the practice of cremation was carried out in Italy, leading to the approval of a law in 1888 according to which cremation was allowed. This made Italy the first European country to introduce cremation in its legal system, but at the same time, one of the last to experience a mass diffusion of this practice, which has always been fiercely fought by the Catholic Church up until recent years. Exploiting the fact that the dispersion of ashes is still prohibited by catholic norms, this work explores the possibility of using the recent trend in cremation practice as an indicator of secularisation.     

The Role of Functions of Aggression in Associations Between Behavioral Inhibition and Activation and Mental Health Outcomes

While the behavioral acitivation system (BAS) has been most consistently linked to externalizing behaviors, the behavioral inhibition system (BIS) has been more closely related to internalizing outcomes. Proactive and reactive aggression have demonstrated a similar pattern of association, with proactive aggression more closely linked to externalizing behavior and reactive aggression more consistently linked to internalizing symptoms. Despite theoretical links, few studies have examined associations between these constructs. Accordingly, the current study examined associations between the BAS and BIS and proactive and reactive aggression, and the role of proactive and reactive aggression in the link between the BAS and BIS and mental health outcomes. The BAS was associated with both proactive and reactive aggression, while the BIS was uniquely related to reactive aggression. Both proactive and reactive aggression appear to be playing a role in associations between the BAS and indicated mental health outcomes. Implications and future directions are discussed.     

‘Eppur si move’: The Association Between Electrophysiological and Psychophysical Signatures of Perceived Movement Illusions

Vibration applied to muscle tendons induces an illusory perception of movement by activating spindle receptors and Ia afferent fibers. While neural structures supporting such illusions are quite defined, functional and psychophysical correlates of their perception have not been deeply investigated. The authors aimed at exploring subjective perception of illusory movements thanks to a repeated-stimulation multimodal approach. The integrated analysis of electroencephalography, source data (standardized low-resolution brain electromagnetic tomography–sLORETA), and psychophysical evaluation pointed at the activation of a frontoparietal sensorimotor network, with prefrontal-medial regions mainly involved in supporting the awareness for illusory movements. Further, illusions showed consistency in terms of presence, vividness, and duration. Finally, superior parietal structures seemed to play an important role in self-attribution of agency and ownership during such experiences.     

Through neural stimulation to behavior manipulation: a novel method for analyzing dynamical cognitive models

The dynamical systems' approach to cognition (Dynamicism) promises computational models that effectively embed cognitive processing within its more natural behavioral context. Dynamical cognitive models also pose difficult, analytical challenges, which motivate the development of new analytical methodology. We start by illustrating the challenge by applying two conventional analytical methods to a well-known Dynamicist model of categorical perception. We then introduce our own analysis, which works by analogy with neural stimulation methods, and which yields some novel insights into the way the model works. We then extend and apply the method to a second Dynamicist model, which captures the key psychophysical trends that emerge when humans and animals compare two numbers. The results of the analysis-which reveals units with tuning functions that are monotonically related to the magnitudes of the numbers that the agents must compare-offer a clear contribution to the contentious debate concerning the way number information is encoded in the brain.
