Education and interactivism: Levels of interaction influencing learning processes

The aim of this paper is to explore some consequences of interactivism within learning situations. Since the original interactivist point of view focused on the Subject/Object relationship, much research has stressed the importance of the non-individualistic aspects of learning, and we have found it revealing to point out the mediation processes occurring inside and outside the S/O relationship (e.g. mediation involving cultural context or artifacts). We have combined different learning theory frameworks, chosen for their complementary conceptions of learning, with a view toward describing the system of interactions involved in teaching/learning processes.The cultural-historical approach to learning insists on the fundamental role of socially constructed tools in human development and education (Vygotsky). Clot and Engeström consider educational institutions as working communities that constrain Subject/Object interaction by rules and habits. Chevallard describes the implications of various categories of actors in the definition of curricula. Within the classroom, besides the obvious mutual influences of individual participants, problems to be solved, as organized by the teacher, influence the attitude of the learner towards the knowledge to be acquired (Brousseau). Furthermore, these situations contain multiple artifacts aimed at facilitating the acquisition of the skills necessary in order to use artifacts outside of the educational context (Rabardel & Bourmaud). Finally, Vergnaud suggests that it is more fruitful to consider the relationship between scheme and situation rather than that between subject and object.We will consider how these various levels of mediation shape the Subject/Object relationship and the learning process.     

Human-centeredness is not a universal feature of young children's reasoning: Culture and experience matter when reasoning about biological entities

We consider young children's construals of biological phenomena and the forces that shape them, using Carey's (1985) category-based induction task that demonstrated anthropocentric reasoning in young urban children. Follow-up studies (including our own) have questioned the generality of her results, but they have employed quite different procedures and either have not included urban children or, when urban samples were included, have failed to reproduce her original findings. In the present study of 4–10-year-olds from three cultural communities, our procedures followed Carey's more closely and replicated her findings with young urban children. However, they yielded quite different results for young rural European American and young rural Native American children. These results underscore the importance of a complex interaction of culture and experience – including both day-to-day interactions with the natural world and sensitivity to the belief systems of the communities – in children's reasoning about the natural world.     

MR Diffusion Tensor Imaging: A Window into White Matter Integrity of the Working Brain

As Norman Geschwind asserted in 1965, syndromes resulting from white matter lesions could produce deficits in higher-order functions and “disconnexion” or the interruption of connection between gray matter regions could be as disruptive as trauma to those regions per se. The advent of in vivo diffusion tensor imaging, which allows quantitative characterization of white matter fiber integrity in health and disease, has served to strengthen Geschwind’s proposal. Here we present an overview of the principles of diffusion tensor imaging (DTI) and its contribution to progress in our current understanding of normal and pathological brain function.     

Trends and developments in community and applied social psychology: JCASP 1991–2010

This paper looks back on the trends and developments in and of the Journal of Community and Applied Social Psychology since its inception twenty years ago. We review to what extent the aims that were originally set for JCASP have been fulfilled. The trends in nationality of authors, themes of publications and their methodology are discussed. Possible implications of these trends and developments for JCASP and its future are pointed at. Copyright © 2010 John Wiley & Sons, Ltd.     

Response priming driven by local contrast, not subjective brightness

We demonstrate qualitative dissociations of brightness processing in visuomotor priming and conscious vision. Speeded keypress responses to the brighter of two luminance targets were performed in the presence of preceding dark and bright primes (clearly visible and flanking the targets) whose apparent brightness values were enhanced or attenuated by a visual illusion. Response times to the targets were greatly affected by consistent versus inconsistent arrangements of the primes, relative to the targets (response priming). Priming effects could systematically contradict subjective brightness matches, such that one prime could appear brighter than the other but could prime as if it were darker. Systematic variation of the illusion showed that response-priming effects depended only on local flanker-background contrast, not on the subjective appearance of the flankers. Our findings suggest that speeded motor responses, as opposed to conscious perceptual judgments, access an early phase of lightness and brightness processing prior to full lightness constancy.     

University psychology clinics in Australia: Their place in professional training

Abstract: There is universal recognition of the need for developmentally appropriate supervised clinical experience in professional psychology training. University clinics were established to provide a bridging function for postgraduate clinical psychology students, assisting the integration of psychological theory and research into real‐world clinical applications and professional identity development. The aim of training in university clinics is to provide opportunities for clinical practice and high‐quality supervision to monitor and shape clinical skills. The experiences gained in external practicum settings complement this initial training but cannot replace it. The recent introduction of Medicare rebates for psychology services has threatened the survival of university clinics because low‐cost psychological treatment is now available from experienced practitioners. This paper provides data on Australian university clinics collected before the introduction of Medicare. Concerted efforts are needed to protect university clinics in order to maintain standards required for accreditation of clinical psychology training programs. The potential impact of the loss of university training clinics is discussed and strategies to ensure their survival are suggested.     

Using confirmatory factor analysis to understand executive control in preschool children: I. Latent structure

Although many tasks have been developed recently to study executive control in the preschool years, the constructs that underlie performance on these tasks are poorly understood. In particular, it is unclear whether executive control is composed of multiple, separable cognitive abilities (e.g., inhibition and working memory) or whether it is unitary in nature. A sample of 243 normally developing children between 2.3 and 6 years of age completed a battery of age-appropriate executive control tasks. Confirmatory factor analysis was used to compare multiple models of executive control empirically. A single-factor, general model was sufficient to account for the data. Furthermore, the fit of the unitary model was invariant across subgroups of children divided by socioeconomic status or sex. Girls displayed a higher level of latent executive control than boys, and children of higher and lower socioeconomic status did not differ in level. In typically developing preschool children, tasks conceptualized as indexes of working memory and inhibitory control in fact measured a single cognitive ability, despite surface differences between task characteristics.     

The mediational role of adolescents' friends in relations between activity breadth and adjustment

This investigation addresses the mediational role of friends' characteristics between adolescents' activity breadth (i.e., variety in activity participation) and their later adjustment. Data were drawn from 2 longitudinal studies: the Childhood and Beyond (CAB; N = 925) study and the Maryland Adolescent Development in Context Study (MADICS; N = 1,338). Adolescents at Time 2 in each study (8th, 9th, and 11th graders in CAB and 8th graders in MADICS) reported on the breadth of their participation across 5 activity settings: sports, religious, volunteering, community, and school. Friends' characteristics and adolescent adjustment were reported by adolescents at Times 1 and 3. Friends' positive characteristics significantly mediated relations between activity breadth and adolescent depressive affect, self-worth, alcohol use, and problem behavior in both studies. Friends' negative characteristics significantly mediated these relations in CAB, but not in MADICS.
