Evidence for differentiation of right hemisphere visual-perceptual functions

Performance on tasks sensitive to right hemisphere dysfunction (facial discrimination and perceptual closure) are reported in eight patients with right hemisphere lesions. Patients demonstrated an apparent double dissociation of performance on the two measures. Site-by-task specificity for the closure task was strongly suggested. Implications for right hemisphere organization and underlying psychological processes are considered.     

In search of closure: subjective contour illusions, Gestalt completion tests, and implications

This study investigates the construct validity of perceptual closure tests (CTs), and isolates a common processing demand from the right-hemisphere. Sixty-seven patients with focal unilateral lesions (34 right side, 33 left side), and 80 control subjects participated. Multivariate analyses indicated that there was substantial age-related variance in all CTs, while sex was variably significant; CTs are not uniform in their discriminating ability, and hence factorially complex; and their specifically right hemisphere-sensitive dimension was subjective contour illusions, and interestingly unrelated to facial discrimination ability. The methodological and theoretical implications are discussed.     

Exploration in outbred mice covaries with general learning abilities irrespective of stress reactivity, emotionality, and physical attributes

Across multiple learning tasks (that place different sensory, motor, and information processing demands on the animals), we have found that the performance of mice is commonly regulated by a single factor ("general learning") that accounts for 30-40% of the variance across individuals and tasks. Furthermore, individuals' general learning abilities were highly correlated with their propensity to engage in exploration in an open field, a behavior that is potentially stress-inducing. This relationship between exploration in the open field and general learning abilities suggests the possibility that variations in stress sensitivity/responsivity or related emotional responses might directly influence individuals' general learning abilities. Here, the relationship of sensory/motor skills and stress sensitivity/emotionality to animals' general learning abilities were assessed. Outbred (CD-1) mice were tested in a battery of six learning tasks as well as 21 tests of exploratory behavior, sensory/motor function and fitness, emotionality, and stress reactivity. The performances of individual mice were correlated across six learning tasks, and the performance measures of all learning tasks loaded heavily on a single factor (principal component analysis), accounting for 32% of the variability between animals and tasks. Open field exploration and seven additional exploratory behaviors (including those exhibited in an elevated plus maze) also loaded heavily on this same factor, although general activity, sensory/motor responses, physical characteristics, and direct measures of fear did not. In a separate experiment, serum corticosterone levels of mice were elevated in response to a mild environmental stressor (confinement on an elevated platform). Stress-induced corticosterone levels were correlated with behavioral fear responses, but were unsystematically related to individuals' propensity for exploration. In total, these results suggest that although general learning abilities are strongly related to individuals' propensity for exploration, this relationship is not attributable to variations in sensory/motor function or the individuals' physiological or behavioral sensitivity to conditions that promote stress or fear.     

Relations Between Suicidal Ideation,Depression, and Emotional Autonomy from Parents in Adolescence

We examined the relations between depression, emotional autonomy quality-related constructs of separation and detachment, and suicidal ideation, focusing on the unique and common contribution that depression, separation and detachment made to suicidal ideation. We also examined gender differences. 403 adolescents, 196 boys and 207 girls, completed self-report measures of depression, separation and detachment, and suicidal ideation. The data showed a significant relation between depression and suicidal ideation both for boys and girls, and between detachment and suicidal ideation only for boys. Results for boys supported an additive model such that depression and detachment each contributed unique variance to boys’ suicidal ideation, and an interactive model such that detachment contributed to exacerbate the risk of suicidal ideation when boys were already at risk because of depression. The data for girls supported an interactive, but not additive, model such that depression and detachment did not contribute independently to girls’ suicidal ideation but in a joint way.     

Problem Behaviors in Adolescence: The Opposite Role Played by Insecure Attachment and Commitment Strength

In this study we examined the relations between insecure attachment styles, commitment and behavioral problems, focusing on the unique and common contribution that avoidant and anxious styles and commitment made to internalizing and externalizing problems. 535 adolescents, 267 boys and 268 girls, aged from 16 to 18 years, completed self-report measures of attachment, identity and problem behaviors. The data showed that both internalizing and externalizing problems were positively related to insecure attachment styles and negatively to commitment. Results supported a unique contribution of both insecure styles to the prediction of internalizing and externalizing problems, whereas commitment negatively predicted only internalizing behaviors. The data supported a joint effect of avoidant attachment and commitment such that commitment contributed to moderate the display of internalizing and externalizing problems among avoidant adolescents.     

Psychometric Properties and Convergent Validity of the Dependency-Oriented and Achievement-Oriented Psychological Control Scale (DAPCS) with Italian Adolescents

This study is aimed to validate the Italian version of the dependency-oriented and achievement-oriented psychological control scale (DAPCS), a self-report questionnaire designed to assess the adolescent’s perception of the two dimensions of psychological control. In Study 1, we assessed factorial validity and reliability of the Italian version of DAPCS with a sample of adolescents. In Study 2, we examined the convergent validity of the Italian version of the DAPCS analyzing the associations between the two domains of psychological control and well-established measures related to them such as strictness/supervision, overprotection, non dependency on parents, and family functioning. Confirmatory factor analyses confirmed the hypothesized two-factor solution of the DAPCS, with a 16 items’ version better fitting the data, for paternal as well as for maternal ratings. High indices of internal consistency indicated that both subscales produced reliable scores. Convergent validity was confirmed by positive associations between the DAPCS’ subscales and measures of strictness and negative associations between the DAPCS’ subscales and measures of global family functioning, both for maternal and paternal ratings. Finally, results evidenced significant effects for adolescents’ and parental gender on achievement-oriented psychological control, with mothers rated higher than fathers by males and fathers rated higher than mothers by females. Overall, the results of these studies indicated that the Italian form of the DAPCS might be a useful instrument to assess the two domain-specific types of parental psychological control among Italian-speaking adolescents.     

Mothering,Fathering, and Italian Adolescents’ Problem Behaviors and Life Satisfaction: Dimensional and Typological Approach

In this study, we explored the relationship between mothering, fathering and Italian adolescents’ problem behaviors and life satisfaction by using both typological and dimensional approaches. From a typological perspective, we examined variations in adolescent adjustment as a function of maternal and paternal parenting styles. From a dimensional perspective, we examined the relationships between crucial dimensions of perceived mothering and fathering (acceptance and strictness) and their contribution to adolescents’ adjustment, for girls and boys separately. A total of 213 adolescents (99 boys and 114 girls), aged from 14 to 16 years of age, completed self-report measures on perceived parenting styles, internalizing and externalizing behaviors, and life satisfaction. Overall, the results confirmed the relationship between maternal and paternal styles and adolescents’ adjustment. Still, the data have not led to the identification of an optimal parenting style among the Italian adolescents because the authoritative, the authoritarian, and the indulgent styles emerged as most favorable in relation to the different dimensions of adjustment and life satisfaction, whereas the neglectful style was most linked to behavioral problems and to low satisfaction. When the focus was on the dimensions, the results showed that for boys, maternal and paternal strictness were negatively related to behavioral problems—both internalizing and externalizing—and positively related to general satisfaction. Meanwhile, for girls, maternal and paternal strictness were negatively related only to externalizing problems. Paternal acceptance was negatively related to girls’ behavioral problems, while maternal acceptance was positively related to girls’ general satisfaction.

Hating among adolescents: Common contributions of cognitive distortions and maladaptive personality traits

The phenomenon of hating is becoming common in adolescence, but it has been rarely investigated. The study aimed to examine the relationships between hating behaviors, maladaptive personality traits, and cognitive distortions, and to explore whether cognitive distortions might intervene in the relationship between personality traits and hating. Method: Participants (200 boys and 202 girls) completed the Hating Adolescents Test (HAT), the Personality Inventory for DSM-5-Brief Form-Children (PID-5), and the How I Think Questionnaire (HITQ). Results: Preliminary results showed significant gender differences in the study’s variables: boys reported higher scores than girls on hating and on cognitive distortion minimizing, whereas no significant differences emerged on maladaptive personality traits. The mediation model showed that the cognitive distortion blaming others mediated the relationship between psychoticism and hating. Conclusions: Data suggested a mediating role of cognitive distortion blaming others in the relationship between psychoticism trait and hating behaviors.

     

Adolescent Effortful Control as Moderator of Father's Psychological Control in Externalizing Problems: A Longitudinal Study

This longitudinal study investigates the moderating role of a temperamental trait, the effortful control, in the relation between father's psychological control and externalizing problems. In Wave 1, the participants included 507 adolescents attending the second classes of two public schools situated in two Italian cities; in Wave 2, 482 adolescents attending the fifth classes of high school participated again in the study. The results demonstrated a positive contribution of paternal achievement-oriented psychological control to externalizing problems and a moderator effect of effortful control in the relationship between the father's psychological control and externalizing problems. These findings extend current knowledge on the role of the father in the difficult task of balancing the promotion of individuality without falling into psychological control that can trigger externalizing problems among adolescents, especially when the temperament of the latter does not foresee the availability of self-regulating abilities that mediate disadvantageous reactivity.
