On the mental representations originating during the interaction between language and vision

The interaction between vision and language processing is clearly of interest to both cognitive psychologists and psycholinguists. Recent research has begun to create understanding of the interaction between vision and language in terms of the representational issues involved. In this paper, we first review some of the theoretical and methodological issues in the current vision–language interaction debate. Later, we develop a model that attempts to account for effects of affordances and visual context on language-scene interaction as well as the role of sensorimotor simulation. The paper addresses theoretical issues related to the mental representations that arise when visual and linguistic systems interact.     

Finding One’s Voice: Psychotherapy for Dissociative Motor Disorders in the Indian Context

Dissociation is a prevalent disorder in India, however there is a lack of evidence-based psychological interventions worldwide. The present paper includes two case studies of dissociative motor disorder with onset in the perinatal period, seeking treatment in the Indian tertiary mental health set-up. Both cases presented with disabling symptoms of paraparesis, and mutism in one. The case series discusses similarities in presentation, socio-cultural contexts, and the psychotherapeutic approach. The psychotherapy process is discussed in detail, with a focus on challenges encountered, therapist reflections and supervision. Insights from treatment are presented, including the melding of approaches, and sensitivity of interventions to the larger socio-cultural framework.

VERBAL CONDITIONING AS A FUNCTION OF AWARENESS AND MANIFEST ANXIETY1

Les AA. examinent la relation entre anxiété et conditionnement verbal d'une part, anxiété et conscience du renforcement d'autre part, dans une épreuve de construction de phrases. L'analyse des résultats non concordants apparus dans les études antérieures et qui concernent la relation entre anxiété et conditionnement verbal suggère L'hypothèse que la direction de cette relation dépend de la conscience des sujets au cours du conditionnement. Les résultats présents montrent que les sujets conscients à forte anxiété se conditionnent mieux que les sujets conscients à faible anxiété. Mais les sujets non conscients à faible anxiété donnent significativement plus de réponses “Je-Nous” que les sujets non conscients à forte anxiété. La non-concordance avec les résultats antérieurs est sans doute due à des différences de population (sujets malades ou normaux).     

Progressive and regressive developmental changes in neural substrates for face processing: testing specific predictions of the Interactive Specialization account

Face processing undergoes a fairly protracted developmental time course but the neural underpinnings are not well understood. Prior fMRI studies have only examined progressive changes (i.e., increases in specialization in certain regions with age), which would be predicted by both the Interactive Specialization (IS) and maturational theories of neural development. To differentiate between these accounts, the present study also examined regressive changes (i.e., decreases in specialization in certain regions with age), which is predicted by the IS but not maturational account. The fMRI results show that both progressive and regressive changes occur, consistent with IS. Progressive changes mostly occurred in occipital-fusiform and inferior frontal cortex whereas regressive changes largely emerged in parietal and lateral temporal cortices. Moreover, inconsistent with the maturational account, all of the regions involved in face viewing in adults were active in children, with some regions already specialized for face processing by 5 years of age and other regions activated in children but not specifically for faces. Thus, neurodevelopment of face processing involves dynamic interactions among brain regions including age-related increases and decreases in specialization and the involvement of different regions at different ages. These results are more consistent with IS than maturational models of neural development.     

Unheard Voices: Experiences of Families Living with HIV/AIDS in India*

This study was aimed at understanding the impact of HIV on the family system in the Indian context. A sample of 20 families caring for a relative living with HIV/AIDS (PLWHAs) was recruited from a HIV counseling clinic at the National Institute for Mental Health and Neuro Sciences and a respite home for PLWHAs in Bangalore City in southern India. Qualitative data were collected from these families using a semi-structured interview guide and recorded in the form of narratives. Analysis of these data revealed the following themes: Stigma and discrimination; disclosure; changes in family functioning; financial difficulties; fears of the family; and helplessness. Each theme was presented in detail and implications for intervention to help these families and their PLWHAs discussed. V.A.S.

Quantitative genetic analysis of latent growth curve models of cognitive abilities in adulthood

Though many cognitive abilities exhibit marked decline over the adult years, individual differences in rates of change have been observed. In the current study, biometrical latent growth models were used to examine sources of variability for ability level (intercept) and change (linear and quadratic effects) for verbal, fluid, memory, and perceptual speed abilities in the Swedish Adoption/Twin Study of Aging. Genetic influences were more important for ability level at age 65 and quadratic change than for linear slope at age 65. Expected variance components indicated decreasing genetic and increasing nonshared environmental variation over age. Exceptions included one verbal and two memory measures that showed increasing genetic and nonshared environmental variance. The present findings provide support for theories of the increasing influence of the environment with age on cognitive abilities.     

Are some gestalt principles deployed more readily than others during early development? The case of lightness versus form similarity

Four experiments investigated how readily infants achieve perceptual organization by lightness and form similarity. Infants were (a) familiarized with elements that could be organized into rows or columns on the basis of lightness or form similarity and tested with vertical versus horizontal bars depicting the familiar versus novel organization or (b) familiarized with bars and tested with elements. For lightness similarity, generalization occurred in both tasks; however, for form similarity, generalization occurred only in the elements --> bars task. The findings indicate that lightness similarity is more readily deployed than form similarity and are discussed in the context of (a) whether the difference reflects speed of application or experience-based learning, (b) evidence from visual agnosic patients and the time course of application of the principles in healthy adults, and (c) development of dorsal and ventral visual processing streams.
