Men appear more lateralized when noticing emotion in male faces

Empirical tests of the "right hemisphere dominance" versus "valence" theories of emotion processing are confounded by known sex differences in lateralization. Moreover, information about the sex of the person posing an emotion might be processed differently by men and women because of an adaptive male bias to notice expressions of threat and vigilance in other male faces. The purpose of this study was to investigate whether sex of poser and emotion displayed influenced lateralization in men and women by analyzing "laterality quotient" scores on a test which depicts vertically split chimeric faces, formed with one half showing a neutral expression and the other half showing an emotional expression. We found that men (N = 50) were significantly more lateralized for emotions indicative of vigilance and threat (happy, sad, angry, and surprised) in male faces relative to female faces and compared to women (N = 44). These data indicate that sex differences in functional cerebral lateralization for facial emotion may be specific to the emotion presented and the sex of face presenting it.     

Allocentric spatial memory in humans with hippocampal lesions

An immersive virtual reality (IVR) system was used to investigate allocentric spatial memory in a patient (PR) who had selective hippocampal damage, and also in patients who had undergone unilateral temporal lobectomies (17 right TL and 19 left TL), their performance compared against normal control groups. A human analogue of the Olton [Olton (1979). Hippocampus, space, and memory. Behavioural Brain Science, 2, 315] spatial maze was developed, consisting of a virtual room, a central virtual circular table and an array of radially arranged up-turned 'shells.' The participant had to search these shells in turn in order to find a blue 'cube' that would then 'move' to another location and so on, until all the shells had been target locations. Within-search errors could be made when the participants returned to a previously visited location during a search, and between-search errors when they revisited previously successful, but now incorrect locations. PR made significantly more between-search errors than his control group, but showed no increase in within-search errors. The right TL group showed a similar pattern of impairment, but the left TL group showed no impairment. This finding implicates the right hippocampal formation in spatial memory functioning in a scenario in which the visual environment was controlled so as to eliminate extraneous visual cues.     

Understanding the Labour Market Participation of Skilled Immigrant Women in Switzerland: The Interplay of Class, Ethnicity, and Gender

Switzerland has recently adopted immigration policies that give preference to skilled migrants, the assumption being that migrants with higher education will integrate easily. Our study of 57 skilled immigrant women from Latin America, the Middle East and Southeastern Europe shows that this assumption is largely unjustified. Most of the women cannot use their social and cultural capital to establish themselves in the upper segments of the labour market. A third are not integrated in the labour market and a quarter occupy positions below their skill-level. A further third work at their skill-level but only irregularly. The differentiated participation of these immigrants in the labour market is well explained by analysing the interplay of class, ethnicity and gender.     

Implicit relational knowing: Its role in development and psychoanalytic treatment

It is increasingly apparent that “something more” than interpretation is needed to bring about change in psychoanalytic treatment. Drawing on clinical and developmental observations, we propose that interactional processes from birth onward give rise to a form of procedural knowledge regarding how to do things with intimate others, knowledge we call implicit relational knowing. This knowing is distinct from conscious verbalizable knowledge and from the dynamic unconscious. The implicit relational knowing of patient and therapist intersect to create an intersubjective field that includes reasonably accurate sensings of each person's ways of being with others, sensings we call the “real relationship.” This intersubjective field becomes more complex and articulated with repeated patient–therapist encounters, giving rise to emergent new possibilities for more coherent and adaptive forms of interaction. During a transactional event that we term a “moment of meeting,” a new dyadic possibility crystallizes when the two persons achieve the dual goals of complementary fitted actions and joint intersubjective recognition in a new form. We argue that such moments of meeting shift the relational anticipations of each partner and allow for new forms of agency and shared experience to be expressed and elaborated. © 1998 Michigan Association for Infant Mental Health     

The Dialogical Approach to Paraconsistency

Being a pragmatic and not a referential approach tosemantics, the dialogical formulation ofparaconsistency allows the following semantic idea tobe expressed within a semi-formal system: In anargumentation it sometimes makes sense to distinguishbetween the contradiction of one of the argumentationpartners with himself (internal contradiction) and thecontradiction between the partners (externalcontradiction). The idea is that externalcontradiction may involve different semantic contextsin which, say A and ¬A have been asserted.The dialogical approach suggests a way of studying thedynamic process of contradictions through which thetwo contexts evolve for the sake of argumentation intoone system containing both contexts.More technically, we show a new, dialogical, way tobuild paraconsistent systems for propositional andfirst-order logic with classical and intuitionisticfeatures (i.e. paraconsistency both with and withouttertium non-datur) and present theircorresponding tableaux.     

What differentiates episodic future thinking from complex scene imagery?

We investigated the contributions of familiarity of setting, self-relevance and self-projection in time to episodic future thinking. The role of familiarity of setting was assessed, in Experiment 1, by comparing episodic future thoughts to autobiographical future events supposed to occur in unfamiliar settings. The role of self-relevance was assessed, in Experiment 2, by comparing episodic future thoughts to future events involving familiar others. The role of self-projection in time was assessed, in both Experiments, by comparing episodic future thoughts to autobiographical events that were not temporal in nature. Results indicated that episodic future thoughts were more clearly represented than autobiographical future events occurring in unfamiliar setting and future events involving familiar others. Our results also revealed that episodic future thoughts were indistinguishable from autobiographical atemporal events with respect to both subjective and objective detail ratings. These results suggest that future and atemporal events are mentally represented in a similar way.
