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.     

The Bilingual Therapist and Transference to Language: Language use in Therapy and its Relationship to Object Relational Context

Through the concept of transference to language, this paper examines the clinical impact of language-related selves of a bilingual therapist, the origin of which is based on the idea that language develops in an object relation context.     

The development of co-representation effects in a joint task: Do children represent a co-actor?

When two adults jointly perform a task, they often show interference effects whereby the other’s task interferes with their own performance (Sebanz, Knoblich, & Prinz, 2003). The current study investigated whether these co-representation effects can be observed in young children. This phenomenon can be used as a criterion for adult-like joint action in children, which has been under debate in existing literature due to the difficulty in identifying what mechanisms underlie the behaviours observed (Brownell, 2011). In Experiment 1, two children performed an adapted Bear Dragon task (Kochanska, Murray, Jacques, Koenig, & Vandegeest, 1996), where children were required to point to a picture when instructed to do so by one puppet and to inhibit pointing when instructed to by the other. In the Same Task condition, both children in a pair were asked to respond to the same puppet, whereas in the Different Task condition, they were asked to respond to different puppets. Children made more errors in the Different Task condition than the Same Task, suggesting that they were experiencing interference from their partner’s task rule. In Experiment 2 children in Different and Same task conditions began with the same task as in Experiment 1 and then switched which puppet to respond to. Switch costs were lower in the Different task condition, consistent with children having already represented the alternative task rule on behalf of their partner during the pre-switch phase. Experiment 3 replicated the effect of Task in a novel computer-based paradigm with children between 4 and 5 years, but not younger. These data provide the first direct evidence that children as young as 4 years co-represent a partner's task during a joint activity, and that younger children may not be capable of co-representation.     

A New Interpretation of the Weighted Kappa Coefficients

Reliability and agreement studies are of paramount importance. They do contribute to the quality of studies by providing information about the amount of error inherent to any diagnosis, score or measurement. Guidelines for reporting reliability and agreement studies were recently provided. While the use of the kappa-like family is advised for categorical and ordinal scales, no further guideline in the choice of a weighting scheme is given. In the present paper, a new simple and practical interpretation of the linear- and quadratic-weighted kappa coefficients is given. This will help researchers in motivating their choice of a weighting scheme.

Moral anger, but not moral disgust, responds to intentionality

We propose that, when people judge moral situations, anger responds to the contextual cues of harm and intentionality. On the other hand, disgust responds uniquely to whether or not a bodily norm violation has occurred; its apparent response to harm and intent is entirely explained by the coactivation of anger. We manipulated intent, harm, and bodily norm violation (eating human flesh) within a vignette describing a scientific experiment. Participants then rated their anger, disgust, and moral judgment, as well as various appraisals. Anger responded independently of disgust to harm and intentionality, whereas disgust responded independently of anger only to whether or not the act violated the bodily norm of cannibalism. Theoretically relevant appraisals accounted for the effects of harm and intent on anger; however, appraisals of abnormality did not fully account for the effects of the manipulations on disgust. Our results show that anger and disgust are separately elicited by different cues in a moral situation.     

Curious eyes: individual differences in personality predict eye movement behavior in scene-viewing

Visual exploration is driven by two main factors - the stimuli in our environment, and our own individual interests and intentions. Research investigating these two aspects of attentional guidance has focused almost exclusively on factors common across individuals. The present study took a different tack, and examined the role played by individual differences in personality. Our findings reveal that trait curiosity is a robust and reliable predictor of an individual's eye movement behavior in scene-viewing. These findings demonstrate that who a person is relates to how they move their eyes.     

Concerns about Appearing Prejudiced Get Under the Skin: Stress Responses to Interracial Contact in the Moment and across Time

Many White Americans are concerned about appearing prejudiced. How these concerns affect responses during actual interracial interactions, however, remains understudied. The present work examines stress responses to interracial contact-both in the moment, during interracial interactions (Study 1), and over time as individuals have repeated interracial contact (Study 2). Results of Study 1 revealed that concerns about appearing prejudiced were associated with heightened stress responses during interracial encounters (Study 1). White participants concerned about appearing prejudiced exhibited significant increases in cortisol "stress hormone" levels as well as increases in anxious behavior during interracial but not same-race contact. Participants relatively unconcerned about appearing prejudiced did not exhibit these stress responses. Study 2 examined stress responses to interracial contact over an entire academic year. Results revealed that White participants exhibited shifts in cortisol diurnal rhythms on days after interracial contact. Moreover, participants' cortisol rhythms across the academic year, from fall to spring, were related to their concerns about appearing prejudiced and their interracial contact experiences. Taken together, these data offer the first evidence that chronic concerns about appearing prejudiced are related to short- and longer-term stress responses to interracial contact. Implications for life in diverse spaces are discussed.     

A glass full of optimism: Enrichment effects on cognitive bias in a rat model of depression

Investigations of cognitive biases in animals are conceptually and translationally valuable because they contribute to animal welfare research and help to extend and refine our understanding of human emotional disorders, where biased information processing is a critical causal and maintenance factor. We employed the "learned helplessness" genetic rat model of depression in studying cognitive bias and its modification by environmental manipulations. Using a spatial judgment task, responses to ambiguous spatial cues were assessed before and after environmental enrichment to test whether this manipulation would cause an optimistic shift in emotional state. Twenty-four congenitally helpless and nonhelpless male rats were trained to discriminate two different locations, "rewarded" versus "aversive." After successful acquisition of this spatial discrimination, cognitive bias was probed by measuring responses to three ambiguous locations. Latencies to "reach" and to actively "choose" a goal pot were recorded alongside exploratory behaviors. An overall strain difference was observed, with helpless rats displaying longer "reach" latencies than nonhelpless rats. This implies a "pessimistic" response bias in helpless rats, underscoring their depressive-like phenotype. No strain differences were observed regarding other behavioral measures. Half of the animals were then transferred to enriched cages and retested. Environmental enrichment resulted in reduced "choose" latencies in both rat strains, associating enrichment with more optimistic interpretations of ambiguous cues. Our results emphasize the suitability of cognitive bias measurement for animal emotion assessment. They extend the methodological repertoire for characterizing complex phenotypes and bear implications for animal welfare research and for the use of animal models in preclinical research.
