Covert visual orienting: Hemifield-activation can be mimicked by zoom lens and midlocation placement strategies

How is attention distributed over visual space when an observer expects a target to occur at one of several possible locations? Two experiments sought to understand the source of the conflict between studies leading to the notions of hemifield activation (Hughes and Zimba 1985) and attentional gradients (Downing and Pinker 1985; Shulman et al. 1985, 1986). Subjects were cued to attend one of the 4 corners of an imaginary square centered at fixation, allowing comparison of uncued locations in the cued and uncued hemifields. In one experiment marking of the 4 locations was varied to determine if providing a ‘target’ for attention is necessary to obtain within-hemifield gradients. RT was faster at the cued location than at the three uncued locations which had equivalent latencies, a pattern that was unaffected by marking of the potential target locations. This result, which is consistent with the notion of a gradient around the attended location is a strong disconfirmation of the hemifield activation hypothesis. The second experiment demonstrated that an unusual procedure for presenting the probe stimuli in Hughes and Zimba (1985) is at least partially responsible for their evidence for uniform hemifield activation. It is proposed that visual attention is directed to visuo-spatial channels with fixed structural properties, and that when attention to two locations is desired, the subject may attend a spatial channel located between them.     

The three-factor structure of the Eysenck personality inventory revealed by a two-step confirmatory procedure

Evidence for the existence of the assumed three-subscale structure of the Eysenck Personality Inventory has been persistent but tenuous. It was suggested that a substantial reason for this may be the discrepancy between the numbers of items in the Lie (L) scale (9 items) and those in the other two scales [Neuroticism (N) and Extraversion (E)] which have 24 items in each. A two-step confirmatory procedure to circumvent this problem was proposed, involving a two-factor analysis of the Neuroticism and Extraversion items, followed by a three-factor analysis of equal numbers of N, E and L scale items. An analysis of the responses of 386 undergraduates demonstrating the proposed procedure revealed in the first step, quite unequivocally, the presence of Neuroticism and Extraversion factors, and in the second step, a third factor clearly congruent with the L scale.     

Does Christianity make a difference?

The human person makes great demands on the physician and calls for unique attention. Hence the doctor-patient relationship calls for the highest ideals of kindness, patience, trustworthiness, generosity and skill. The Catholic physician brings to these demands a specific meaning: ministering to the sick is to see Christ in them and to show Him to them.     

Personal advertisements of male-to-female transsexuals,homosexual men,and heterosexuals

Transsexuals, because of their attempts at gender reversal, offer a unique opportunity to study self-presentation, social roles, and stereotypes. The present study is a content analysis of personal advertisements of male-to-female transsexuals (TM, N =99), homosexual (HoM, N =64) and heterosexual men (HM, N =99), and heterosexual women (HW, N =99). Advertisements were coded for the presence or absence of 11 characteristics either offered or sought, based on the 1984 work of Deaux and Hanna. The content of TM personal advertisements was significantly different from those of HW, HM, or HoM. TM mentioned physical characteristics and sincerity, and requested friendship most often; HoM mentioned sexuality most often; HM offered financial security and status in the form of occupation, and listed marital status most often; and HW offered personality characteristics and attractiveness most often. Several factors may contribute to the pattern of differences observed, including the fact that TM were more likely to be seeking friendship than sexual partners, in contrast to the other three groups.
