Externalization, Counter-examples, and the Abstract Selection Task

The five experiments reported in this paper examined the effect of two theoretically motivated, explicit mental procedures on performance in different versions of the four-card, abstract selection task. There was no overall benefit as a result of carrying out these procedures; instead, performance depended upon the extent to which subjects carried out the procedures successfully. Most crucially, the experiments demonstrated that correct selection depends not simply upon envisaging the right counter-example, but upon identifying those cards that could contain potential counter-examples. Such findings are broadly consistent with the theory of mental models. However, contrary to the theory, identification is not sufficient for correct selection. The externalization technique used in these studies provides a way to examine the loci of performance differences in the selection task and therefore provides a way to test rival theoretical claims.     

Visual search: detection, identification, and localization.

In two studies, observers searched for a single oblique target in a field of vertical distractors. In one experiment, target detection and identification (left versus right tilt) were compared. In another experiment, detection and localization were compared for the left versus the right half of the display. Performance on all three tasks was virtually identical: if a target could be detected, it could also be identified and localized. A review of previous studies generally supports the conclusion that performance on the three tasks is similar. This argues against current search theories, which rest heavily on data showing differences in identification and localization.     

Lesbian Identities: An Examination of Sexual Behavior and Sex. Role Attribution as Related to Age of Initial Same-Sex Sexual Encounter

To investigate some of the differences among lesbians proposed by Ponse (1978), 43 self-defined lesbians were interviewed and administered questionnaires. Three groups were distinguished on the basis of age of initial lesbian sexual experience, and those in the earliest and latest age groups were compared. Group 1 lesbians engaged in same-sex sexual relations prior to age 17 (perhaps before the establishment of their personal identity), were more sexually active at an earlier age, see themselves as having more stereotypic masculine traits, and define themselves as exclusively homosexual. Group 2 lesbians did not engage in same-sex sexual relations until after the age 20, were typically emotionally involved heterosexually prior to defining themselves as lesbians, and may be somewhat bisexual in activity. Both groups see themselves as being high in stereotypic feminine traits and have fairly active heterosexual histories. The heterogeneous nature of the "coming out" process for lesbians and its implications for future research are discussed.     

Beyond androgyny: The emergence of sex-role transcendence as a theoretical construct

Recent trends in sex-role research are reviewed with the purpose of showing a paradigm shift in the kinds of issues and questions thought to be important for an understanding of sex-role development. Two recent advances, conceptualizations of androgyny and sex-role transcendence are described with particular emphasis on the emergence of sex-role transcendence as a new theoretical construct. It is argued that while personality, social-learning, and structural-developmental theories account for sex-role identity and androgyny, only structural-developmental theory provides an adequate conceptual framework for the construct of sex-role transcendence. Questions are raised concerning the empirical demonstration of the concept.
