An area specifically devoted to tool use in human left inferior parietal lobule

A comparative fMRI study by Peeters et al. (2009) provided evidence that a specific sector of left inferior parietal lobule is devoted to tool use in humans, but not in monkeys. We propose that this area represents the neural substrate of the human capacity to understand tool use by using causal reasoning.     

The valence of action outcomes modulates the perception of one's actions

When interacting with the world, we need to distinguish whether sensory information results from external events or from our own actions. The nervous system most likely draws this distinction by comparing the actual sensory input with an internal prediction about the sensory consequences of one's actions. However, interacting with the world also requires an evaluation of the outcomes of self-action, e.g. in terms of their affective valence. Here we show that subjects' perceived pointing direction does not only depend on predictive and sensory signals related to the performed action itself, but also on the affective valence of the action outcome: subjects perceived their movements as directed towards positive and away from negative outcomes. Our findings suggest that the non-conceptual perception of the sensory consequences of self-action builds on both sensorimotor information related directly to self-action and a post hoc evaluation of the affective action outcome.     

Morally disengaged and unempathic: do cyberbullies fit these definitions? An exploratory study

In recent years, the phenomenon of cyberbullying has been gaining scholars' growing interest under various aspects, including its overlap with face-to-face bullying. Nevertheless, its relationships with cognitive and affective empathy, proactive and reactive aggression, and moral disengagement, constructs that proved to be crucial in distinguishing aggressive subjects from their targets and nonaggressive peers in traditional bullying, still represent, to some extent, an unexplored domain. The main purpose of the present exploratory study was to investigate the associations between cyberbullying and the mentioned constructs among Italian adolescents. 819 high-school students (mean age 16.08) were administered a battery of standardized tools, along with Cyberties, a new instrument created to assess the prevalence of (and the type of involvement in) different forms of electronic assaults. Analyses of variance were conducted to compare four roles ("pure" bullies, "pure" victims, bully victims, and noninvolved subjects). Participants who identified themselves as cyberbullies or cyberbully victims showed significantly higher levels of overall moral disengagement and of both types of aggression. Cyberbullies also displayed a lack of affective empathy. Our findings are in line with the ones in extant literature about correlates of traditional and electronic forms of bullying. Implications for prevention strategies are discussed.

Divergent Thinking and Age-Related Changes

Aging can affect cognition in different ways. The extent to which aging affects divergent thinking is unclear. In this study, younger and older adults were compared at the performance on the Torrance Test of Creative Thinking in visual and verbal form. Results showed that older adults can think divergently as younger participants, although they produce fewer visual ideas. This finding involves implications for active aging, given that also older adults can be still capable to produce original ideas and improve living conditions surrounding them.     

You better play 7: mutual versus common knowledge of advice in a weak-link experiment

This paper presents the results of an experiment on mutual versus common knowledge of advice in a two-player weak-link game with random matching. Our experimental subjects play in pairs for thirteen rounds. After a brief learning phase common to all treatments, we vary the knowledge levels associated with external advice given in the form of a suggestion to pick the strategy supporting the payoff-dominant equilibrium. Our results are somewhat surprising and can be summarized as follows: in all our treatments both the choice of the efficiency-inducing action and the percentage of efficient equilibrium play are higher with respect to the control treatment, revealing that even a condition as weak as mutual knowledge of level 1 is sufficient to significantly increase the salience of the efficient equilibrium with respect to the absence of advice. Furthermore, and contrary to our hypothesis, mutual knowledge of level 2 induces, under suitable conditions, successful coordination more frequently than common knowledge.
