Same kinematics but different objects during action observation: Detection times and motor evoked potentials

Motor resonance refers to the fact that an observed action is online subliminally reenacted. The aim of the present paper was to verify if, on equal terms of kinematics, the to-be-grasped object's intrinsic properties are influencing the observers' motor behaviour. A detection time and a single pulse transcranial magnetic stimulation experiment were performed to verify the effects of a change of object's intrinsic properties artificially made on a video showing a grasping action. In particular, the object substituting the original one was not graspable by the showed movement. Results indicated an influence of object's intrinsic properties: Detection times were delayed and motor evoked potentials were reduced when the movement shown was not suitable to grasp the object. These results are interpreted as an evidence that during grasping action observation the motor system of the observer is influenced not only by the seen movements but also by the to-be-grasped object.     

Changing history: doctored photographs affect memory for past public events

We investigated how doctored photographs of past public events affect memory for those events. Italian participants viewed either original images or misleading digitally doctored images depicting the 1989 Tiananmen Square protest in Beijing and a 2003 protest in Rome against the war in Iraq, and they subsequently answered questions about those events. Viewing the doctored images affected the way participants remembered the events. Those who viewed the doctored photograph of the Beijing event estimated that a larger number of people participated in it. Those who viewed the doctored photograph of the Rome event rated the event as more violent and more negative, recalled more physical confrontation, damage to property, and injuries to demonstrators, and were less inclined to participate in future protests. Both younger and older adult participants were affected by the manipulation. Results indicate that doctored photographs of past public events can influence memory, attitudes and behavioural intentions. Copyright © 2007 John Wiley & Sons, Ltd.     

Gender and mathematics: attitudes and stereotype threat susceptibility in Italian children

Two experiments investigated the development of attitudes toward mathematics and stereotype threat susceptibility in Italian children. Experiment 1 involved 476 elementary school boys and girls and produced evidence of gender differences in self-confidence in one's own mathematical ability and in gender stereotyping of mathematics during elementary school. It also provided initial evidence for a decrement in 10-year-old girls' mathematics performance when stereotype threat was made salient by reminding participants that extraordinary achievement in mathematics is typically a male phenomenon. Experiment 2 (N=271) replicated these findings and expanded them to middle school-age participants. Its results suggest that during middle school, the patterns observed in elementary school consolidate, and the stereotypes begin to produce detrimental effects in girls.     

Parental influences on memories of parents and friends

The authors evaluated the role parent-child relationship quality has on two types of memories, those of parents and those of friends. Participants were 198 Italian university students who recalled memories during 4 separate timed memory-fluency tasks about their preschool, elementary school, middle school, high school and university years. Half were instructed to recall memories involving parents and the remainder memories involving friends. Moreover, parent-child relationships were assessed by the Network of Relationships Inventory (NRI; W. Furman & D. Buhrmester, 1985) and Adolescents' Report of Parental Monitoring (D. M. Capaldi & G. R. Patterson, 1989). Results showed that men with positive parent-son relationships had more memories of parents and more affectively positive memories of friends, supporting a consistency model positing similarity between parent-child relationships and memories of friends. Women with positive parental relationship quality had more affectively positive memories of parents but for friends, positive relationship quality only predicted positive memories when young. At older ages, especially middle school-aged children, negative parent-daughter relationships predicted more positive memories of friends, supporting a compensatory model. The gender of parent also mattered, with fathers having a more influential role on affect for memories of friends.     

The Role of Vulnerable and Grandiose Narcissism in Psychological Perpetrated Abuse Within Couple Relationships: The Mediating Role of Romantic Jealousy

Abstract

The aim of this study was to analyze the direct and indirect relationships between the two phenotypes of narcissism, vulnerable and grandiose, and the tendency to perpetrate psychological abuse, exploring the mediating role of romantic jealousy. Our sample included 473 participants (213 males), aged 18–30 years (M?=?22.74; SD = 2.81), involved in a stable romantic relationship. A structural equation modeling was conducted to test our model and a multigroup analysis was performed to test gender differences. Results show that the two forms of narcissism are both linked to psychological perpetrated abuse, but in different ways. Vulnerable narcissism was linked to psychological abuse only indirectly, through the role of romantic jealousy. On the contrary, grandiose narcissism was positively and directly associated with psychological abuse within the romantic relationship. Moreover, the model was invariant across genders. Limitations, strengths, and theoretical and clinical implications are discussed.
