Visual object imagery and autobiographical memory: Object Imagers are better at remembering their personal past

In the present study we examined whether higher levels of object imagery, a stable characteristic that reflects the ability and preference in generating pictorial mental images of objects, facilitate involuntary and voluntary retrieval of autobiographical memories (ABMs). Individuals with high (High-OI) and low (Low-OI) levels of object imagery were asked to perform an involuntary and a voluntary ABM task in the laboratory. Results showed that High-OI participants generated more involuntary and voluntary ABMs than Low-OI, with faster retrieval times. High-OI also reported more detailed memories compared to Low-OI and retrieved memories as visual images. Theoretical implications of these findings for research on voluntary and involuntary ABMs are discussed.     

Knowledge,Truth and Plausibility

From antiquity several philosophers have claimed that the goal of natural science is truth. In particular, this is a basic tenet of contemporary scientific realism. However, all concepts of truth that have been put forward are inadequate to modern science because they do not provide a criterion of truth. This means that we will generally be unable to recognize a scientific truth when we reach it. As an alternative, this paper argues that the goal of natural science is plausibility and considers some characters of plausibility.     

Distinguishing Personality Psychopathology Five (PSY–5) Characteristics Associated With Violent and Nonviolent Juvenile Delinquency

This study examined the relationship between the Minnesota Multiphasic Personality Inventory–Adolescent (MMPI–A) Personality Psychopathology Five (PSY–5) scales and violent and nonviolent juvenile delinquency. Participants were 260 adolescent boys and girls in a forensic setting. Results indicated that Disconstraint (DISC), a marker of behavioral disinhibition and impulsivity, was associated with nonviolent delinquency, whereas Aggressiveness (AGGR), which is characterized by the use of instrumental aggression and interpersonal dominance, was specifically associated with violent delinquency. These findings are consistent with expectations based on empirical findings in the broader personality literature linking the construct of disinhibition with externalizing psychopathology as well as the literature identifying callous-unemotional aggression as a risk factor for violence.     

A DDL Approach to Pluralistic Ignorance and Collective Belief

A group is in a state of pluralistic ignorance (PI) if, roughly speaking, every member of the group thinks that his or her belief or desire is different from the beliefs or desires of the other members of the group. PI has been invoked to explain many otherwise puzzling phenomena in social psychology. The main purpose of this article is to shed light on the nature of PI states – their structure, internal consistency and opacity – using the formal apparatus of Dynamic Doxastic Logic, and also to study the sense in which such states are “fragile”, i.e. to identify plausible conditions under which a PI state cascades into a state of shared belief as the result of announcement.

Gender and Age Differences in Brazilian Children's Friendship Nominations and Peer Sociometric Ratings

This article reports on an investigation into the relation between young adults' retrospective reports of their mothers' and fathers' division of household labor (egalitarian or traditional) and parenting styles (authoritative, permissive, authoritarian, or disengaged). Participants' own gender attitudes were also tested in relation to parents' division of labor and parenting. The sample included 294 women and men (M =19-years old) who were raised in 2-parent households and came from a range of ethnic backgrounds. When mothers' parenting was evaluated, permissive parenting was more likely among those from egalitarian households whereas authoritarian parenting was more likely among those from traditional households. When fathers' parenting was evaluated, authoritative parenting was more likely among participants from egalitarian households and disengaged parenting was more likely among those from traditional households. The association between fathers' parenting style and division of labor was specific to the division of childcare (rather than housework). Participants' gender attitudes were not related to parents' division of labor or parenting style.     

Feelings or cognitions? Moral cognitions and emotions as longitudinal predictors of prosocial and aggressive behaviors

There is debate regarding the roles of sociomoral cognitions and emotions in understanding moral development. The short-term longitudinal relations among perspective taking, sympathy, prosocial moral reasoning, prosocial behaviors and aggression in adolescents were examined. Participants were 489 students (M age = 12.28 years, SD = .48; 232 boys) in public and private schools from predominantly middle class families in Valencia, Spain. Students completed measures of perspective taking, sympathy, prosocial moral reasoning, prosocial behaviors, and aggressive behaviors. Overall, structural equation modeling analyses showed that moral reasoning and emotions were interrelated and predicted both prosocial behaviors and aggression. Discussion focuses on the relevance of both social cognitions and emotions in moral development.     

The perceptual salience of symmetrical and asymmetrical sections of a line

A vertical line segment intersecting a horizontal one at different crossing points generates line sections. Visual perception of such line sections was investigated here in two experiments. In both experiments participants were most accurate and precise when they had to reproduce symmetrical sections. Interestingly, the different asymmetrical sections of a line were not equivalent in terms of participants' performance: constant errors changed as a function of sections and the error curve was nicely interpolated by the composition of two harmonics of the line length. In consistence with the harmonic fitting of the data, we propose that the perceptual salience of specific asymmetrical sections is a byproduct of the automatic triggering of a line midpoint identification process. Being perceptually tuned to symmetry warps our visual representation of the line, which results in systematic misperceptions. The way of bringing present and past experimental findings into a unitary whole is proposed.     

Links between social information processing in middle childhood and involvement in bullying

The aim of this study was to investigate the way in which bullies, victims, bully/victims, and those not involved process social information. A peer nomination measure of bullying and victimization was administered twice over an interval of one year. The sample consisted of 236 (126 girls and 110 boys) children at the beginning of the study (T1) and 242 children one year later (T2) (mean age: 8 years). To test how children responded when provoked, both spontaneously and after prompting, we used provocation scenarios, and to test their attributional interpretations we used ambiguous scenarios. The results showed that children not involved in bullying responded in an assertive way to provocation more often than bullies and victims, but not more than bully/victims. In general, aggressive answers diminished after prompting and irrelevant answers increased. Appealing for the help of an adult or a peer was the strategy most often chosen. When the intent of the perpetrator was ambiguous, bully/victims attributed more blame, were angrier, and would retaliate more than those not involved. Partly similar results were obtained when stably involved children were compared with those unstably involved. Suggestions for intervention are presented. Aggr.
