Chiasm and hyperdialectic: re-conceptualizing sensory deprivation in infancy

The literature on sensory processing disorders in institutionalized infants highlights the impact of early deprivation on infant perception. Through a Merleau-Pontian, hyperdialectic analysis of the extraordinary development of infant perception under circumstances of severe deprivation the intimate link between environmental affordances and perceptual systems becomes apparent. This paper offers an updated reading of Merleau-Ponty’s late work as a philosophy of systems (“structures”, “forms”, “gestalts”, as he called them) and outlines some fertile philosophical concepts and methods developed by Merleau-Ponty in The visible and the Invisible. Merleau-Ponty’s concept of the chiasm, understood from a systems perspective, and his method of the hyperdialectic are applied in a child case study of an infant who suffered severe neglect in a Romanian orphanage.     

Ethical aspects of HIV/AIDS prevention strategies and control in Malawi

HIV/AIDS prevention campaigns have been overshadowed by conflicting, competing, and contradictory views between those who support condom use as a last resort and those who are against it for fear of promoting sexual immorality. We argue that abstinence and faithfulness to one partner are the best available moral solutions to the HIV/AIDS pandemic. Of course, deontologists may argue that condom use might appear useful and effective in controlling HIV/AIDS; however, not everything that is useful is always good. In principle, all schools of thought and faith seem to agree on the question of faithfulness for married couples and abstinence for those who are not married. But they differ on condom use. On the ground, the situation is far more complex. We simply lack a single, entirely reliable way to resolve all disagreements regarding HIV/AIDS prevention strategies.

Group comparisons of DSM-IV subtypes of chronic depression: validity of the distinctions, part 2

The nosology of chronic depression in Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV, American Psychiatric Association, 1994) is highly complex and requires clinicians to differentiate among several chronic course subtypes. This study replicates an earlier investigation (J. McCullough et al., 2000; see record 2000-05424-007) that found few differences among Diagnostic and Statistical Manual of Mental Disorders (3rd ed. rev.; DSM-III-R; American Psychiatric Association, 1987) categories of chronic depression. In the present study, 681 outpatients with chronic major depression, double depression, recurrent major depression without full interepisode recovery, and chronic major depression superimposed on antecedent dysthymia were compared. Few differences were observed on a broad range of demographic, clinical, psychosocial, family history, and treatment response variables. The authors suggest that chronic depression should be viewed as a single, broad condition that can assume a variety of clinical course configurations.     

Evidence of separable spatial representations in a virtual navigation task

Three experiments investigated spatial orientation in a virtual navigation task. Subjects had to adjust a homing vector indicating their end position relative to the origin of the path. It was demonstrated that sparse visual flow was sufficient for accurate path integration. Moreover, subjects were found to prefer a distinct egocentric or allocentric reference frame to solve the task. "Turners" reacted as if they had taken on the new orientation during turns of the path by mentally rotating their sagittal axis (egocentric frame). "Nonturners," by contrast, tracked the new orientation without adopting it (allocentric frame). When instructed to use their nonpreferred reference frame, both groups displayed no decline in response accuracy relative to their preferred frame; even when presented with reaction formats based on either ego or allocentric coordinates, with format unpredictable on a trial, both groups responded highly accurately. These findings support the assumption of coexisting spatial representations during navigation.     

Affect in Play Scale-Preschool Version: Validation on a Sample of School Age Italian Children

The Affect in Play Scale-Preschool version is a semi-structured measure of cognitive and affective pretend play processes using a 5?min standardized play task devised for preschool children. This study investigated an extension of the scale in a sample of 333 children, aged 6–10 years. Participants were assessed using another measure of play processes, the Affect in Play Scale, a divergent thinking task, the Alternate Uses Test, a measure of school coping, the School Coping measure, and a measure of empathy, the Index of Empathy for Children. External validity with these measures was investigated, using correlational analyses. Construct validity of the scale was assessed using a confirmatory factor analysis approach. A correlated two-factor structure with a cognitive and an affective factor demonstrated the best fit. Implications for the use of this extension to assess cognitive and affective processes in pretend play and developmental outcomes were discussed.     

Expressed Emotion,Parental Stress,and Family Dysfunction Among Parents of Nonclinical Italian Children

Expressed emotion (EE) is an index of the amount of emotion typically displayed by a family member or caretaker characterized by high emotional involvement, hostility or criticism. The aims of the current study were (a) to examine EE, stress and helplessness in childcare, and family functioning in mothers and fathers of elementary and junior high school children without clinical mental health problems living in a “nonclinical” family context; (b) to assess relationships between child age, gender, socio-economic status and EE; and (c) to investigate whether there are some factors—in a “normal family” context—that play a crucial role in the quality of EE. EE, assessed using the Five Minute Speech Sample (FMSS), and questionnaires assessing parenting alliance, family functioning, parenting stress index, and the parent’s state of helplessness in caring for the child were completed by a community-based Italian sample of mothers and fathers of children (N = 381) aged 6–14 years (M = 9.8, SD = 2.25). As expected, low rates in all FMSS variables were found for mothers and fathers, without significant differences between them. Mothers and fathers who showed high EE scores reported higher family non-adaptive functioning. Mothers also reported higher parental stress and higher Helplessness in caring for the child. Mothers’ stress and fathers’ reports of higher family non-adaptive functioning were the most consistent predictors of EE. Further research is needed to highlight associations between EE and family functioning.
