The semantic structure of vision verbs: A psycholinguistic investigation of Italian

The aim of the present study was to investigate the semantic dimensions that contribute to the mental representation of vision verbs in Italian. In Experiment 1, a group of experts (psychology faculty members) was asked to list the semantic attributes necessary for describing a set of Italian vision verbs (Phase 1) and a group of students rated the extent to which each of these attributes was appropriate to characterise these verbs (Phase 2). In Experiment 2, the conceptual organisation of vision verbs was assessed through Multidimensional Scaling (MDS) using direct judgements of pairwise similarity between vision verbs (e.g., “vedere-guardare”). The results show that six of the attributes generated in Phase 1 are useful for describing the pattern of similarity ratings obtained in Experiment 2, namely attention, certainty, cognitive content, control, duration, and intentionality.     

Pathways Linking Child Physical Abuse,Depression, and Aggressiveness across Genders

Previous research suggests that child physical abuse, depression, and aggressiveness are linked, but gender differences remain poorly understood. This study examined gender differences in the mediational relationships among these constructs, after controlling for the confounding effects of other negative life events. Men and women completed questionnaires about physical abuse and negative life events that occurred prior to age 18, depressive symptoms, and aggressiveness. Results indicated significant gender differences in the pathways between child physical abuse and depression, and between child abuse and aggressiveness, with direct and mediating links pertaining only to men. These findings suggest that links among child physical abuse, depression, and aggressiveness are specific to men, and negative life events might play a more potent role for women.     

The role of rigid motion in newborns' face recognition

The study investigated whether dynamic information promotes newborns' ability to recognize a face. After being habituated to a face undergoing an ordered sequential head rigid motion (Exp. 1), 1- to 3-day-old newborns fully recognized the familiar face shown in the profile pose, as documented by a preference for the profile pose of a novel face. When familiarized to an ordered sequence of different viewpoint static images of a face (Exp. 2), newborns failed to recognize the profile pose of the familiar face, their visual exploration of the familiar and novel faces being at chance. Habituation to a random head rigid motion (Exp. 3) allowed only a partial recognition of face identity, as newborns preferred the profile pose of the familiar, rather than the novel, face. Rigid head motion is an important source of information for newborns' face recognition, probably aiding the derivation of a three-dimensional face structure.     

Differential roles of the basolateral amygdala and nucleus basalis magnocellularis during post-reactivation contextual fear conditioning reconsolidation in rats

The roles of the basolateral amygdala and nucleus basalis magnocellularis in fear conditioning reconsolidation were investigated by means of tetrodotoxin bilateral inactivation performed 96 h after conditioning, immediately after reactivation training. Footshocks of 1.2 mA intensity were employed to induce the generalization phenomenon. Basolateral amygdala inactivation disrupts the contextual fear response and its generalization but not acoustic CS trace retention, when measured 72 and 96 h after tetrodotoxin administration. Nucleus basalis magnocellularis functional inactivation does not affect memory post-reactivation phase of any of the three conditioned fear responses. The present findings show a differential role of the two structures in fear memory reconsolidation and can be a starting point for future investigation of the neural circuits subserving generalization.     

Scientific Communication and Stereotype Change1

The aim of this experiment is to examine whether communicating the results of social psychological research improves out‐group stereotypes and diminishes in‐group bias. The experimental material consisted of 2 communications: one described Hamilton and Gifford's (1976) experiment on illusory correlation (Experiment 1); the other described Sherif's (1966) studies on summer camps. The results of the present experiment show that knowledge of Sherif's findings had no effect on evaluations, whereas an awareness of the experiment on illusory correlation produced a boomerang effect, accentuating, rather than diminishing, in‐group bias. A second experiment revealed that the persuasive power of a scientific message on stereotypes depends on whether in‐groups and out‐groups are cogni‐tively present in the message acquisition phase.     

Irrational and Metacognitive Beliefs Mediate the Relationship Between Content Beliefs and GAD Symptoms: A Study on a Normal Population

Cognitive Behavioral Therapy (CBT), Rational Emotive Behavior Therapy (REBT) and Metacognitive Therapy (MCT) models show both similarities and differences in conceptualizing anxiety. This work assumes that REBT’s irrational and MCT’s metacognitive beliefs play a mediation role while CBT’s disorder specific content beliefs act as triggers. This hypothesis is tested using a regression model in which metacognitive and irrational beliefs play a mediation role while content disorder beliefs are independent variables. This paper applied this model to generalized anxiety disorder (GAD), a psychiatric diagnosis in which anxiety is the major feature. In GAD, the specific content beliefs are negative problem orientation and intolerance of uncertainty. Therefore, 149 non clinical subjects completed 4 self-report questionnaires: the Negative Orientation to the Problems Questionnaire and the Intolerance of Uncertainty Scale as measures for content cognitive beliefs, the Attitudes and Beliefs Scale for irrational beliefs, and the Metacognitive Questionnaire 30 Items Version for metacognitive beliefs. The generalized anxiety disorder questionnaire was chosen in order to measure anxiety as dependent variable. Regression analyses confirmed that irrational and metacognitive beliefs mediate the relation between cognitive content beliefs and GAD. We clinically interpret mediation as a second level regulation.     

Children’s sense of reality: The development of orbitofrontal reality filtering

Orbitofrontal reality filtering denotes a memory control mechanism necessary to keep thought and behavior in phase with reality. In adults, it is mediated by the orbitofrontal cortex and subcortical connections and its failure induces reality confusion, confabulations, and disorientation. Here we investigated for the first time the development of this mechanism in 83 children from ages 7 to 11 years and 20 adults. We used an adapted version of a continuous recognition task composed of two runs with the same picture set but arranged in different order. The first run measures storage and recognition capacity (item memory), the second run measures reality filtering. We found that accuracy and reaction times in response to all stimulus types of the task improved in parallel across ages. Importantly, at no age was there a notable performance drop in the second run. This means that reality filtering was already efficacious at age 7 and then steadily improved as item memory became stronger. At the age of 11 years, reality filtering dissociated from item memory, similar to the pattern observed in adults. However, performance in 11-year-olds was still inferior as compared to adults. The study shows that reality filtering develops early in childhood and becomes more efficacious as memory capacity increases. For the time being, it remains unresolved, however, whether this function already depends on the orbitofrontal cortex, as it does in adults, or on different brain structures in the developing brains of children.     

Day-Hospital Multifocal Integrated Treatment for Anorexia Nervosa in Adolescents: A One-Year Follow-Up

The current guidelines for treatment of Anorexia Nervosa (AN) in children and adolescents recommend an integrated multidisciplinary approach as the elective intervention for this disorder. Nevertheless, there is insufficient evidence on the results of an integrated approach for the treatment of AN adolescent patients, especially in a Hospital setting. This study aims to analyze clinical and psychological changes occurring in adolescent patients after completion of a Day-Hospital Multifocal Integrated Treatment (MIT) for Anorexia Nervosa. The sample consisted of 60 adolescents with AN or Eating Disorder Not Otherwise Specified (EDNOS) restrictive type, aged 11 to 18 years, and their parents. Clinical course was evaluated at 3, 6 and 12-month follow-up periods. Our results showed clinical remission in a good percentage of patients. In general, we found a significant reduction of the eating psychopathology, whereas we did not detect any significant improvement in body dissatisfaction, perfectionism, and relational difficulties. This positive trend was confirmed at 3, 6, and 12-month follow-up, despite the increase of drop-outs. These results suggest that the proposed treatment is reasonably effective, because it aims to contain and reduce the acute phase of the disease in a limited time and in a hospital setting, but it is necessary to continue the treatment with targeted psychotherapeutic interventions to address the deeper psychological discomfort underlying the eating disorder.
