Independent perceptual reversals for simultaneously presented ambiguous figures.

In two successive experiments using the divided visual field paradigm with vertical or horizontal division, two ambiguous figures, the Rubin's vase-face or the Necker cube, were projected to the right and left or to the upper and lower visual hemifields of 108 healthy volunteers. Stimulation time was 120 s. The main hypotheses were (a) that different percepts of the same ambiguous figure may be simultaneously experienced in the two hemifields and (b) that the type (vertical vs. horizontal) of visual field division influences the reversal frequency and the temporal interdependence of the percepts. Results from the first experiment showed that the temporal interdependence of reversals was very low for both ambiguous figures, suggesting that during part of the stimulation time the subjects could experience different percepts of the same figure (e.g. a vase in the right and face profiles in the left visual hemifields). The second experiment showed that this perceptual dissociation occurred on average during one third of the stimulation time. In both experiments the type of visual field division did not influence either frequency or temporal interdependence of the reversals. When one single ambiguous figure was presented in the centre of the screen, the number of reversals was approximately the sum of the reversals observed with two figures presented simultaneously each in one hemifield.

A Comparison of Attachment representations to Mother and Father using the MCAST.

The aim of the current study was to examine the factorial structure of the Manchester Child Attachment Story Task (MCAST), using a father doll to address the child's attachment representation to father. While the MCAST, a doll story completion task measuring attachment representations in early childhood, has been validated for use with a mother doll, its use for assessing attachment to father is relatively unexplored. Thus, an additional aim was to compare the factorial structure of the child's attachment representation to father and mother, respectively. We analyzed data from 118 first-grade children who underwent counterbalanced administration of the MCAST with a mother and father doll, respectively, within a period of three months. Exploratory factorial analysis revealed similar, three-factor solutions for attachment to father and mother, with a first factor capturing the child's (scripted) knowledge of secure base/safe haven and a second factor reflecting intrusive and conflict behavior. The third factor was different in the father and mother representations, capturing self-care and role-reversal in attachment to father and disorganization in attachment to mother. Findings support the potential usefulness of the MCAST for exploring the father-child relationship and highlight a need for further research on early attachment representations to father.

Psychometric Properties of the Child Attachment Interview in Italian Context: A Focus on Normative and Specific Clinical Groups in School-Aged Children.

While attachment assessments developed for infancy and adulthood are well established, no such gold standard measure exists for school years, where measures are not yet sufficiently robust. Nevertheless, the last decade has witnessed some progress in this field with the development of the Child Attachment Interview (CAI), a semistructured interview designed to access children's mental representations of their attachment relationships. This study aimed to test the validity and reliability of the CAI for an Italian population, using a normative group and a clinical group of disruptive behavior disorder and somatic symptom disorder patients. A total sample of 311 Italian children (213 normative and 98 clinical) aged 8 to 15 years completed a battery of measures assessing attachment, verbal IQ, and symptomatology. The psychometric properties of the CAI alongside other children (Kerns Security Scale, Inventory of Parent and Peer Attachment) and parents (Adult Attachment Interview) attachment measures in normative sample, as well as the distribution of attachment patterns in normative and clinical samples, were examined. The results revealed the CAI to have adequate interrater and test-retest reliability, as well as discriminant, and convergent validity. Significant differences in the CAI's distribution of attachment patterns for normative and specific clinical groups were found. Taken together, the findings show that the CAI Italian version is a reliable and valid measure for assessing attachment in school years and beyond.

Hemispheric asymmetries in the perception of rapid (timbral) and slow (nontimbral) amplitude fluctuations of complex tones.

Hemispheric asymmetries for processing rapid (timbral) and slow (nontimbral) amplitude fluctuations of complex tones were investigated in 32 right-handed nonmusicians. Two monaural matching-to-sample tests with contralateral white noise and attention directed to 1 ear were used, 1 with tones presenting slow fluctuations of amplitude and 1 with tones presenting rapid fluctuations of amplitude perceived as different timbres. Stimuli were generated by altering the amplitude envelope of a steady state complex tone. Dependent variables were reaction time and accuracy. The results suggest an important role for the right hemisphere in the perception of temporal variations of intensity of sounds both when these variations are rapid and perceived as timbral qualities and when they are slow and perceived as changes of loudness.

Factor structure and criterion validity of an enlarged version of the parental bonding instrument

Factorial structure and criterion validity of an enlarged version of the Parental Bonding Instrument (PBI-E) were evaluated in a community sample of young adults. This enlarged version was obtained by adding parental favouritism (FAV) and put-down/shaming (PUT_D) to the original care and overprotection (OV) scales as recalled by the offspring. Factor analysis suggested a five factor model as the best solution, identifying CARE, FAV and PUT_D and splitting the overprotection items into two factors, denial of psychological autonomy (DPA) and discouragement of behavioural freedom, (DBF) with Cronbach’s alphas ranging from .77 to .92. These five scales were correlated with depression and anxiety of the offspring, measured by BDI and STAI. Both of them correlated negatively with care and positively with the other parental scales, as expected by Parker’s theory on the role of affectionless control for the psychopathological vulnerability of the children. A series of hierarchical regression analyses, including CARE, DPA and DBF at the first step and FAV and PUT_D at the second step, showed that the latter enhanced the predictive power of the instrument. Overall these findings: (1) suggest a five factor structure for the PBI-E and (2) confirm the criterion validity of the PBI scales in respect to children’s depression and anxiety, providing also compelling evidence for the incremental validity of Gilbert’s scales (AU)

Relationship between parental narcissism and children’s mental vulnerability: mediation role of rearing style

The hypothesis that parental narcissism is related to depression and anxiety of the young adult children and that this relationship is mediated by the parental rearing style as reported by the offspring was investigated. Subjects were 409 young adults (264 females), aged 22.85 (SD= 2.00) and their parents. Parental narcissism was measured with the Narcissistic Personality Inventory (NPI); the rearing style, as remembered by the offspring, was measured with the Parental Bonding Instrument (PBI) that includes Parkers’s scales of care and overprotection and Gilbert’s scales of put-down/shaming and favouritism; depression and anxiety were assessed with the Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI) respectively. Two total mediation models (one for fathers and one for mothers), including parental NPI as a predictor, PBI scales as mediators and children’s scores on BDI and STAI as criteria, showed adequate goodness of fit indices. The sums of indirect effects of both paternal and maternal narcissism on children’s depression and anxiety, via all rearing style dimensions, were significant. These results suggest that parental narcissism is related to children’s depression and anxiety and that this relationships is mediated by the rearing style as recalled by the offspring (AU)

Italian version of the defense style questionnaire.

The Defense Style Questionnaire (DSQ) assesses defensive behavior by empirically evaluating conscious derivatives of defense and coping mechanisms in everyday life. It was developed on the assumption that defenses can be ordered along a maturity-immaturity continuum and tend to group into clusters, or defensive styles. The original factor analytical study, by Bond et al. (1983) identified four styles, called maladaptive, image-distorting, self-sacrifice, and adaptive styles. Successive studies only partially confirmed this factor structure. We present the factor structure and the main psychometric features of the Italian version of the questionnaire. The DSQ was translated into Italian by the back-translation method and administered to a sample of 294 men (mean age, 33.33 years) and 333 women (mean age, 32.38 years). An exploratory factor analysis identified three factors largely corresponding to Bond's maladaptive, image-distorting, and adaptive defensive styles and to analogous factors identified by other authors. Accordingly, three defense style scales were constructed, containing respectively 37, 17, and 12 items. These scales showed intercorrelations compatible with the hierarchical model of defensive functioning at the base of the questionnaire, acceptable, though ameliorable, test-retest reliabilities (r's = .79, .63, and .81, respectively) and, with the exception of the Adaptive Style scale, sufficient internal consistencies (alphas: .85, .72, .57). However, only the Maladaptive Style scale, probably due to its greater length, showed values of reliability and internal consistency high enough to warrant clinical use in its present form. Further investigation is required to find new items that may improve the reliability of the Image-Distorting and the Adaptive Style scales.
