- Description: M.A. (Psychology) , Research investigating the connection between Functional Hemispherical Asymmetry (FHA) and perception of affect in clinical as well as normal populations, is characterised by contradictory findings with regard to the role of the different hemispheres, especially as regards the perception of various valencies of emotions. Although a majority of studies indicates that the right hemisphere (RH) is superior in the perception of all valencies and emotions - positive as well as negative - there are numerous studies indicating a possible differential processing of positive and negative emotions by the hemispheres. Although various researchers try to lay the above contradictory findings and the general lack of consensus at the door of methodological problems/inequalities or error variances, the literature is increasingly pointing to the existence of evidently reliable individual differences between people as regards their hemispherical functioning. The problem investigated in the current study, is to determine the possible role of the organismic variables in FHA, i e variables seated in the individual who is making the observation. In this study, the focus is specifically on the role of sex and the temperament dimension of introversion-extraversion. The objectives of this study are to determine whether there are significant differences in the direction of these hemispherical differences, as well as the relative performance, of groups divided according to sex and temperament characteristics, and whether the relevant organismic variables offer a possible means of explaining the contradictions in research results on FHA and the perception of emotion. In this study, the measuring of FHA is operationalised in terms of the differential performance, measured in terms of accuracy and speed of observation (response latency) of the hemispheres in the perception of different valencies of emotional stimuli (positive versus negative, and approach versus avoidance emotions).. The subject population comprised a group of students selected in terms of sex and temperament (introversion-extraversion). Selection in terms of introversion-extraversion was done on the basis of subjects' performance in the Personality Questionnaire Form B (Schepers, 1991): persons falling in the lower and upper three stanines of the scale respectively were identified as introverts and extraverts. Only right-handed subjects with no history of brain injury were used for the study. Differential hemispherical performance in terms of response accuracy and latency was determined by means of the Divided Visual Field Technique (DVFT). Although the reliability data of this technique are generally not entirely satisfactory when measured in terms of psychometric test standards, an effort was made to enhance the reliability of the technique in this study by controlling specific stimulus and response variables (inter alia the exposure time and the use of both hands for a response) during the experimental design.

The quest for intimacy : a phenomenological exploration of the cyberspace version thereof

- Description: D.Litt. et Phil. (Psychology) , Abstract: Online dating sites have become hugely popular and powerful forums for forming interpersonal relationships. As a consequence, the influence of digital modes of communication on the nature of interpersonal intimacy has become a highly relevant issue that requires scientific examination from many different perspectives. The main aim of this study was to explore the lived experiences of intimacy of a cohort of individuals who used online dating to seek a connection/ relationship(s) with others. Given the specific research questions and the nature of the phenomenon involved, a hermeneutic phenomenological approach, located within the interpretive paradigm, and grounded by the philosophical thinking of Heidegger and Gadamer was deemed an appropriate means of inquiry. Given observations that there may be distinct differences in the nature of agendas and, possibly, meanings that individuals who find themselves in different age cohorts and development phases attach to intimacy, the research inquiry focused on the experiences of a group of middle-aged online daters. Fifteen participants, of whom seven were men and eight were women, participated in the study. Their ages ranged between 45 years and 68 years with a mean of 58.13 years. All described themselves as heterosexual in their orientation to mate seeking. A combination of in-depth F2F interviews and written narratives were used for collecting data. Two participants chose to submit exclusively narrative accounts of their experiences; eight participants opted for F2F interviews as the sole basis of the research interaction; five participants opted for a combination of a F2F interview and the submission of some supplementary written notes. The analysis was conducted in a way that was congruent with the philosophical foundation of Heidegger and Gadamer. From this vantage point, the process of analysis was aimed at identifying the horizons of meaning from which participants re-membered and re-lived and made meaning of their experiences and their ways of being intimate in a cyber context. The findings revealed intimacy as constructed and lived online to be a multifaceted phenomenon. Six distinct horizons emerged from the analysis, each of which illuminated the lived experience of the phenomenon from a specific vantage point. The horizon of Situatedness located participants in the contexts from whence they embarked on their online journey(s). The next four horizons, namely, A Seductive Space, The Multifarious Shapes of Time, The Contentious Body, and The Revealing and Concealing Text reflected constituents of participants’ experiences of intimate relating that may, compared to intimate relating in the F2F realm, be uniquely related to the mediated medium of the internet and to being-in-cyberspace as a world. The final horizon,..
