Social Representations of Gender in Peer Interaction and Cognitive Development

The paper discusses how social representations of gender and their development in childhood relate to the structuring of communication on collaborative problem solving in the educational context and the consequences of such communication dynamics for learning and cognitive development. In the theoretical framework and the empirical work outlined an emphasis is given on the articulation of different levels of analysis (intra‐personal, inter‐personal, inter‐group/positional and ideological/social representations) (Doise, W. 1986. Levels of Explanation in Social Psychology: European Monographs in Social Psychology. Cambridge: Cambridge University Press) in a way that explanatory power is increased for understanding the often contradictory findings in the literature around gender talk in mixed‐sex dyads in the educational context.     

Anomalous brain dominance and the immune system: Do left-handers have specific immunological patterns?

Geschwind and Behan (1982) and Geschwind and Galaburda (1985a, 1985b, 1985c) suggested a correlation between brain laterality and immune disorders. To test whether this hypothesis holds true not only for the frequency of immune diseases and circulating autoantibodies, but extends also to cellular immunity, we examined the association between handedness and markers of cellular immunity. Twenty-seven left-handed and 37 right-handed subjects were serologically screened for cellular parameters and 22 left-handed subjects were typed for human leukocyte antigen (HLA). When compared to the right-handers, the left-handed group showed a significant decrease in the inflammatory cell types CD3(+) T cells (total T cells), CD4(+) T cells (T-helper cells), and HLA-Dr (MHC-II, antigen-presenting cells) as well as in the CD19(+) cells (B cells) and CD16/CD57(+) cells (natural killer cells). We assume a relationship exists between cerebral hemispheric specialisation and the immune system not only for humoral but also for cellular immunity, and we discuss the role of the major histocompatibility complex in neurological and immunological development.     

The constructive role of gender asymmetry in social interaction: Further evidence

Two hundred and sixty‐four children aged 6.5–7.5 years (first graders) took part in a pre‐test, interaction, and post‐test experiment working on a spatial transformation task known as the ‘village task’. Cognitive progress was assessed by pre‐ to post‐test gains in both an immediate and delayed post‐test in dyads and individual participants as a control. The results indicate clear links between particular pair types with both communication processes and with learning and cognitive developmental outcomes. The present study demonstrates that gender can act as a source of status asymmetry in peer interaction to influence communication, learning, and cognitive development in same‐ and mixed‐sex dyads.     

Cowden Syndrome

Cowden syndrome is an autosomal dominant inherited cancer syndrome characterized by multiple hamartomas which may develop in any organ. Mucocutaneous papillomas and trichilemmomas are hallmarks of the syndrome. Affected individuals are at high risk of developing both benign and malignant disease of the thyroid and breast. Epithelial thyroid carcinoma occurs in 3–10% of affected individuals while women have a 25–50% lifetime risk of developing adenocarcinoma of the breast. Because of the cancer risk, it is imperative that health care providers recognize Cowden syndrome. The susceptibility gene has been localized to 10q22-23 and preliminary studies demonstrate no genetic heterogeneity.     

Coexisting and conflicting self-referential conceptual systems: A model for describing malfunctioning in the contemporary family-implications for therapy

In the proposed model, intra- and interpersonal conflicts are formalized as information-processing problems created by inconsistent self-referential conceptual systems. Three self-referential conceptual systems corresponding to the three forms of family lifetraditional-rural, industrial-nuclear, information-transactional-coexist and intermingle, creating difficulties in the coordination of interactions.Each of these ecotheories is viewed as a constellation of hierarchically-ordered, dynamic, cognitive-emotional structures which express the particular family system's perceptions of itself in relation to its environment and life in general. The model correlates in an integrative manner phenomena at the level of societal change with evolving patterns of intrapersonal and familial dynamics and provides a framework for guiding preventive and therapeutic interventions. The evolving ecotheory model presented in this work follows the metatheoretical paradigms of cognitive science, self-reference and self-organization. The attempted synthesis has been achieved in the context of the unifying concepts and principles of General Systems Theory.     

International Collaboration as Construction of Knowledge and its Constraints

In this paper I draw on Piaget and Habermas to underline the importance of the theoretical distinction between social relations of constraint and social relations of cooperation for reflecting upon inter-institutional projects. I argue that the socio-cultural approach to collaboration has some important limitations that restrict ideological critic and emancipatory research. The limitations of this approach can be located in its epistemological assumptions, a homogenized notion of culture and a weakness in articulating the intrapersonal, inter-personal, inter-group/positional and social representational/ideological levels of analysis. As an empirical example of this I discuss the Sloan centres for family research.

Asymmetries in peer interaction: The effect of social representations of gender and knowledge asymmetry on children's cognitive development

This study examines the role of social representations of gender and knowledge as sources of asymmetry on the features of children's interactions as well as on their cognitive development. The research was carried through an innovative pre‐test, first interaction, second interaction, post‐test design. One hundred fifty‐nine children of the same age (6.5–7.5 years old) but of different levels of knowledge of a spatial‐transformation task collaborated in same‐sex and opposite‐sex dyads to find a joint solution. In the first interaction, a child less developmentally advanced (NC) had to work with a child more developmentally advanced (TC), whereas in the second interaction of the same gender composition, the same NC had to work with a fresh NC. Cognitive progress was assessed using pre‐test to post‐test gains. The results revealed that the gender composition of the pairs and knowledge asymmetry influence not only the behavioral patterns and strategies that each partner employs in the interaction but also the cognitive outcomes of the children. These findings shed more light to the process through which socio‐cognitive conflict gets resolved, which was considered until now a “black box.” Copyright © 2012 John Wiley & Sons, Ltd.     

Semantic interference during object naming in agrammatic and logopenic primary progressive aphasia (PPA)

This study examined the time course of object naming in 21 individuals with primary progressive aphasia (PPA) (8 agrammatic (PPA-G); 13 logopenic (PPA-L)) and healthy age-matched speakers (n = 17) using a semantic interference paradigm with related and unrelated interfering stimuli presented at stimulus onset asynchronies (SOAs) of −1000, −500, −100 and 0 ms. Results showed semantic interference (SI) (i.e. significantly slower RTs in related compared to unrelated conditions) for all groups at −500, −100 and 0 ms, indicating timely spreading activation to semantic competitors. However, both PPA groups showed a greater magnitude of SI than normal across SOAs. The PPA-L group and six PPA-G participants also evinced SI at −1000 ms, suggesting an abnormal time course of semantic interference resolution, and concomitant left hemisphere cortical atrophy in brain regions associated with semantic processing. These subtle semantic mapping impairments in non-semantic variants of PPA may contribute to the anomia of these patients.     

Information need,affect, and cognition of autonomic activity

Several studies have shown that bogus feedback of physiological change induces a greater liking for attractive stimuli. Other research suggests that the affective change induced by bogus feedback requires an opportunity to visually search change-associated stimuli for information which can account for its purported physiological effect. While there is considerable agreement among theorists that a greater disliking should obtain when the stimuli are unattractive (but a lack of data supporting this contention), there is disagreement about whether information searching is directed equally toward change-associated stimuli and no-change stimuli, or toward change-associated stimuli alone.Results of the present study support the contention that stimulus features determine the kind of affect experienced: change-associated slides depicting nudes are rated as more attractive than no-change-associated nudes, and change-associated slides depicting accident vitctims are rated as more repulsive than no-change-associated victims. Information seeking data are more consistent with the contention that information needs exist after both types of feedback.
