Neural correlates of perceptual narrowing in cross‐species face‐voice matching

Integrating the multisensory features of talking faces is critical to learning and extracting coherent meaning from social signals. While we know much about the development of these capacities at the behavioral level, we know very little about the underlying neural processes. One prominent behavioral milestone of these capacities is the perceptual narrowing of face–voice matching, whereby young infants match faces and voices across species, but older infants do not. In the present study, we provide neurophysiological evidence for developmental decline in cross‐species face–voice matching. We measured event‐related brain potentials (ERPs) while 4‐ and 8‐month‐old infants watched and listened to congruent and incongruent audio‐visual presentations of monkey vocalizations and humans mimicking monkey vocalizations. The ERP results indicated that younger infants distinguished between the congruent and the incongruent faces and voices regardless of species, whereas in older infants, the sensitivity to multisensory congruency was limited to the human face and voice. Furthermore, with development, visual and frontal brain processes and their functional connectivity became more sensitive to the congruence of human faces and voices relative to monkey faces and voices. Our data show the neural correlates of perceptual narrowing in face–voice matching and support the notion that postnatal experience with species identity is associated with neural changes in multisensory processing ( Lewkowicz & Ghazanfar, 2009 ).     

Categorization in everyday life: the effects of positive and negative categorizations on emotions and self‐views

This study investigates how everyday categorization experiences affect people's emotional responses and self‐views. A representative Dutch population sample (N = 463) was asked to recount a situation in which they were categorized by others. This resulted in a range of categories that were spontaneously evoked by research participants. Participants were asked to think of a situation either where the categorization resulted in negative or in positive expectations about the self. Positive categorization elicited more positive emotions and agreement than negative categorization. However, when positive expectations about the self were formed, people found it less easy to detect that these were based on external categorizations, and were less likely to protest. Mediational analyses showed that because detection was impaired, exposure to positive categorization resulted in lower self‐confidence than exposure to negative categorization.

COCAINE ADDICTS AND THEIR FAMILIES: AN EMPIRICAL STUDY OF THE PROCESSES OF IDENTIFICATION

The processes of identification between adolescent cocaine addicts and their parents were studied in 402 subjects, in total 134 familial triads (father"mother"son), subdivided into two groups of 67 triads, one of these groups having as the child an adolescent of masculine sex dependent on cocaine and the other, equal in number, being a control group, duly matched for age and socio-economic status. The instrument employed was the Rorschach test (1922), limited to the application of the Lerner Defense Scale (LDS; Lerner & Lerner, 1980). The findings in the affected triads showed up as consistent statistically for the presence of intense processes of pathological identification, especially between father and son, a sign of the importance of the presence of disturbances of paternal function in the development of this addiction. The utilisation of very regressive defence mechanisms, above all of projective identification, was the predominant mode of procedure in triads with a dependent child. In comparisons between the fathers the odds ratio (OR) for projective identification was 8.66 to 1, which points to the association between cocaine addiction and the primitive mental functioning of the fathers. With empirical methodology these findings serve to corroborate the psychoanalytical conclusions based on studies of single case studies, testifying that the dysfunctions of identificatory phenomena in familial functioning are predominant in the mental organisation of cocaine addicts.     

Adaptation of Nussbaum's Capabilities Framework to Community Mental Health: A Consumer‐Based Capabilities Measure

The capabilities approach provides a rich evaluative framework to guide transformative change in the community mental health system. This study reports the content and construct validity and psychometric properties of a contextualized measure of the extent to which mental health programs foster achieved capabilities. The Achieved Capabilities Questionnaire for Community Mental Health (ACQ‐CMH), adapted from Nussbaum's capabilities framework, was developed previously with consumer collaboration. Content validity was assessed through a collaborative process, involving a panel of eight consumers, staff members, and senior researchers. The resulting shorter version (ACQ‐CMH‐98) was completed by 332 community mental health consumers sampled throughout Portugal. Factor (PCA) analysis, internal consistency reliability, and test–retest reliability over 2 weeks (N = 33) showed good psychometric properties. The resulting six‐factor structure with 48 items explains 48.88% of the total variance (KMO = 0.89; Bartlett p = .00). Internal consistency of the obtained dimensions ranges from .91 to .76. Associations of the measure with recovery, quality of life, and psychological distress scales add further evidence of construct validity. The adaptation of Nussbaum's framework stressed specific components that may enhance understanding and change within the community mental health system.     

Comparison of outcome in men and women after treatment in psychiatric security hospitals in Germany

Previous research has shown that forensic psychiatric treatment reduces reoffending, rehospitalization and premature mortality. Treatment outcome varies with diagnosis, but little is known about the influence of sex, psychosocial adjustment and aftercare. To assess these variables, we interviewed male and female patients discharged from three psychiatric security hospitals in Germany in the years 2010–2017. Participants were interviewed at discharge (n = 609) and 1 year later (n = 366) about reoffending, readmissions, substance use and psychosocial adjustment. Among patients with substance use disorder (SUD), 14% reoffended, 20% were re-hospitalized and 60% maintained abstinence. Among patients with severe mental disorder, 5% reoffended and 13% were re-hospitalized. Significant sex differences were found in offenders with SUD. The results suggest that sociodemographic and disorder-related risk factors are associated with treatment success and that female patients with SUD might need a specific treatment approach. Sex-specific aspects, diagnosis and psychosocial adjustment should be considered in forensic psychiatric treatment and risk assessment.     

Developmental changes in mother-infant face-to-face communication: birth to 3 months

This study documented the growth of the earliest form of face-to-face communication in 16 mother-infant dyads, videotaped weekly during a naturalistic face-to-face interaction, between 1 and 14 weeks, in 2 conditions: with the infant in the mother's arms and with the infant semi-reclined on a sofa. Results showed a curvilinear development of early face-to-face communication, with a significant increase occurring between Week 4 and Week 9 depending on the dyad. After 2 months, trajectories diverged into 2 groups: I whose duration of face-to-face communication continued to increase and I whose duration peaked and then began to decrease. After the 1st month, the duration of face-to-face communication was significantly longer when the infant was on the sofa rather than in the mother's arms. In the latter condition, during the 3rd month, girls spent a significantly longer time than boys in face-to-face communication. These findings suggest that context (infant being held vs. not being held) interacts with the infant's age and sex in affecting mother-infant communication.     

Cognitive changes following subthalamic nucleus stimulation in two patients with Parkinson disease

The limits of a drug therapy in severe forms of Parkinson disease have led to refining neurosurgery on the basal ganglia. Deep brain stimulation of the subthalamic nucleus has been recognized as one of the most promising techniques to decrease "off" motor symptoms and motor fluctuations, allowing a reduction of drug therapy and limiting side effects of the drugs. There is still open debate on the possible consequences of chronic subthalamic stimulation in other ways, apart from motor symptoms, of general cognitive performance. We examined and followed two patients with Parkinson disease for 9 mo. after surgery for deep stimulation, studying their cognitive performances. There is a general amelioration of cognitive performances, in particular as far as linguistic capabilities is concerned. We discuss the possible significance of these results, reminding strenuously that only two patients were involved, so the potential for generalization is seriously limited.     

The burden of benevolent sexism: how it contributes to the maintenance of gender inequalities

This study (N = 235) examines the responses of male and female participants to information about the alleged endorsement of either hostile or benevolent sexist beliefs by a sample of either men or women. We predicted that people endorsing benevolent sexist statements would be less likely to be perceived as sexist than those endorsing hostile sexist views, and examined the judgmental process through which people fail to recognize benevolent sexism as a form of prejudice. We argue that benevolent sexists do not match the mental prototype of sexist perpetrators, because they are seen as likeable. Our results confirm that because benevolent sexists are evaluated more positively than hostile sexists, they are less likely to be seen as sexists. This judgmental process occurs relatively independently of emotional responses to hostile vs. benevolent sexism. These results are discussed in terms of their relevance to the maintenance of gender inequalities. Copyright © 2005 John Wiley & Sons, Ltd.
