Head-centred meridian effect on auditory spatial attention orienting

Six experiments examined the issue of whether one single system or separate systems underlie visual and auditory orienting of spatial attention. When auditory targets were used, reaction times were slower on trials in which cued and target locations were at opposite sides of the vertical head-centred meridian than on trials in which cued and target locations were at opposite sides of the vertical visual meridian or were not separated by any meridian. The head-centred meridian effect for auditory stimuli was apparent when targets were cued by either visual (Experiments 2, 3, and 6) or auditory cues (Experiment 5). Also, the head-centred meridian effect was found when targets were delivered either through headphones (Experiments 2, 3, and 5) or external loudspeakers (Experiment 6). Conversely, participants showed a visual meridian effect when they were required to respond to visual targets (Experiment 4). These results strongly suggest that auditory and visual spatial attention systems are indeed separate, as far as endogenous orienting is concerned.     

Construction and validation of the Gender Attitude Inventory,a structured inventory to assess multiple dimensions of gender attitudes

Three studies describe the development and initial validation of the Gender Attitude Inventory (GAI), a structured inventory that assesses attitudes toward the multiple objects that organize college students' thoughts and feelings about sex and gender. An intergroup relations perspective was used to specify the universe of gender-related targets and to construct a preliminary instrument. Factor analyses of the results of two sequential studies yielded a 109-item inventory with 14 content-specific attitude areas and three second-order factors. In Study 3 GAI scales were shown to have acceptable internal consistency and temporal stability, as well as convergent and discriminant validity. In terms of race/ethnicity, most respondents were white (ranging from 69% to 82% across the three studies).     

PSAAL: A LabVIEW 3 program for data acquisition and analysis in psychophysiological experiments

PSAAL (Physiological Signals Acquisition and Analysis in LabVIEW language) is a group of seven programs, written in LabVIEW 3.0 language and specialized for acquisition, analysis, reduction, and display of peripheral and central physiological data. The main characteristics of the programs are the wide range of use for most short-duration psychophysiological paradigms and the easy-to-use graphic interface. In addition, two noteworthy features of LabVIEW are included: the portability of the programs on Macintosh, PowerMac, IBM, HP-UX, and SUN computers, and the capability of handling acquisition on many National Instruments A/D boards, including the low-cost ones. PSAAL performs acquisition and simple reduction of peripheral physiological responses with 12- or 16-bit resolution according to the A/D board used. Analysis includes conversion of electrocardiogram into heart rate, the elaboration of the main parameters of skin conductance responses, electromyogram, startle reflex, and averaging of evoked potentials or other event-related physiological responses, under different experimental conditions. The programs allow the user to perform the organization of the data in a spreadsheet ready for most statistical packages and without the use of other spreadsheet applications.     

On maximal intermediate predicate constructive logics

We extend to the predicate frame a previous characterization of the maximal intermediate propositional constructive logics. This provides a technique to get maximal intermediate predicate constructive logics starting from suitable sets of classically valid predicate formulae we call maximal nonstandard predicate constructive logics. As an example of this technique, we exhibit two maximal intermediate predicate constructive logics, yet leaving open the problem of stating whether the two logics are distinct. Further properties of these logics will be also investigated.Presented by H. Ono     

The postmodern counsellor: Some implications for practice,theory, research and professionalism

What is postmodernism? What are the implications of the death of God, science and the subject for counselling? Further questions include: To what extent does postmodernism, show that behavioural, humanistic, existential, and most psychoanalytic theories are delusional in that they would have the clients/patients believe that they are the core, the centre, the subject? What are the dangers of seeing ‘others’ practically, theoretically and when conducting research as either enhancing our narcissism and/or the counselling order? In terms of an ethical practice, can the postmodern counsellor stop counselling from reverting to a technique orientated mechanism of professional vested interests, and instead find a better way for us all to put the other first?     

Maternal employment and socioeconomic status as factors in daughters' career salience: Some substantive refinements

Research on children of working mothers has indicated that an important relationship exists between maternal employment and subsequent career salience of female offspring. Effects caused by socioeconomic factors have been noted in this relationship but have not been examined either systematically or over time. In the present study, socioeconomic differences were controlled for examination of longitudinal data on established critical factors in career salience of female college graduates. Multiple regression models were estimated for three points in time, covering an eight-year period, for subsamples of single and married women. Details about mother's employment history, respondent's recollection of the attitudes of family members concerning that employment, and indicators of daughter's sex-role ideology were independent variables. Maternal employment was significantly related to both single and married daughters' career salience but in opposite directions and accounted for only a minimum of the observed variance. Related maternal employment variables are associated with career salience of single women early in their postbaccalaureate careers and are not associated with the career salience of married women until somewhat later. Sex-role ideology was important for the career salience of married women but not for single women. The importance of a generalizable context for these findings is discussed.Support for this research was provided in part by a grant from the University of Wisconsin Graduate School and NIMH Grant Number MH-13112 to the Departments of Sociology and Psychiatry, Duke University. This research was based on a part of the author's doctoral dissertation.     

The Del Greco Assertive Behavior Inventory

Previous research in the area of assertiveness training has been examined with respect to the definitions of assertive, aggressive, and nonassertive behavior and the prominent assertion model. Logical inconsistencies have led to a refinement of the definitions of these behaviors, the inclusion of passive aggressive behavior, and the testing of a new two-dimensional model of assertion. The present study has developed a psychometric test to measure assertive, aggressive, nonassertive, and passive aggressive behavior in the college dormitory population. In addition, support was demonstrated for the validity of the two dimensional model of assertion. The instrument development was divided into four phases: item generation, item evaluation and revision, reliability testing and item analysis, and validity testing. Data analysis supported the two-dimensional model of assertion. In addition, an 86-item Del Greco Assertive Behavior Inventory designed for use with college dormitory students has weathered preliminary validity and reliability testing.     

Proving quadratic reciprocity: explanation,disagreement, transparency and depth

Gauss’s quadratic reciprocity theorem is among the most important results in the history of number theory. It’s also among the most mysterious: since its discovery in the late eighteenth century, mathematicians have regarded reciprocity as a deeply surprising fact in need of explanation. Intriguingly, though, there’s little agreement on how the theorem is best explained. Two quite different kinds of proof are most often praised as explanatory: an elementary argument that gives the theorem an intuitive geometric interpretation, due to Gauss and Eisenstein, and a sophisticated proof using algebraic number theory, due to Hilbert. Philosophers have yet to look carefully at such explanatory disagreements in mathematics. I do so here. According to the view I defend, there are two important explanatory virtues—depth and transparency—which different proofs (and other potential explanations) possess to different degrees. Although not mutually exclusive in principle, the packages of features associated with the two stand in some tension with one another, so that very deep explanations are rarely transparent, and vice versa. After developing the theory of depth and transparency and applying it to the case of quadratic reciprocity, I draw some morals about the nature of mathematical explanation.

     

Infants of “depressed” mothers interact better with their nondepressed fathers

To determine whether infants of “depressed” mothers interact better with their nondepressed fathers, twenty-six 3- to 6-month-old infants were videotaped during face-to-face interactions with their parents. The “depressed” mother group consisted of twelve 3- to 6-month-old infants and their “depressed” mothers and nondepressed fathers. The control group was composed of 14 nondepressed mothers and nondepressed fathers and their 3- to 6-month-old infants. In the “depressed” mother group, the nondepressed fathers received better interaction ratings than the “depressed” mothers. In turn, the infants received better interaction ratings when they interacted with their nondepressed fathers than with their “depressed” mothers. In contrast, nondepressed fathers and mothers and their infants in the control group did not differ on any of their interaction ratings. These findings suggest that infants' difficult interaction behaviors noted during interactions with their “depressed” mothers may not extend to their nondepressed fathers. The data are discussed with respect to the notion that nondepressed fathers may “buffer” the effects of maternal depression on infant interaction behavior.
