Cross-modal interaction between vision and hearing: A speed—accuracy analysis

Cross-modal facilitation of response time (RT) is said to occur in a selective attention task when the introduction of an irrelevant sound increases the speed at which visual stimuli are detected and identified. To investigate the source of the facilitation in RT, we asked participants to rapidly identify the color of lights in the quiet and when accompanied by a pulse of noise. The resulting measures of accuracy and RT were used to derive speed-accuracy trade-off functions (SATFs) separately for the noise and the no-noise conditions. The two resulting SATFs have similar slopes and intercepts and, thus, can be treated as overlapping segments of a single function. That speeded identification of color with and without the presence of noise can be described by one SATF suggests, in turn, that cross-modal facilitation of RT represents a change in decision criterion induced by the auditory stimulus. Analogous changes in decision criteria might also underlie other measures of cross-modal interactions, such as auditory enhancement of brightness judgments.     

The Temporal Automated System for Taste Experiments (TASTE).

We describe a new, open flow device for presenting taste stimuli to human subjects under controlled conditions of timing. The device delivers each stimulus as a mist to the participant's tongue through one of 16 nozzles attached to a linear slide. Software controls the position of the slide, the duration of the stimulus, and the duration of the pre- and poststimulus water rinses and records the responses of the participant. Temporal characteristics of this system make it especially applicable to studies on the role of attention in taste perception.

Transcendence and the Moral Self: Identity Integration, Religion, and Moral Life

Although moral reasoning is able to account for some of the variability in moral behavior, much remains unexplained. Recently, a number of components of personality have been proposed as bridging the gap between moral reasoning and moral behavior. The present study investigates the role that identity integration (the extent to which one's moral values have become integrated into identity) and religious orientation (one's motivation for engaging in religious practice) play in moral functioning. A sample of 60 undergraduates was assessed on identity integration, religious orientation, moral reasoning, and self-reported altruism. We found positive correlations among moral reasoning, identity integration, intrinsic religious orientation, and self-reported altruism. A hierarchical regression analysis, however, revealed moral reasoning to be the only significant predictor of self-reported altruistic behavior. We discuss the relationship between moral reasoning and identity integration and the extent to which the intrinsic religious orientation scale may be a measure of identity integration in the religious domain.     

Test Difficulty and Stereotype Threat on the GRE General Test1

This study investigated (a) the ability to minimize or eliminate stereotype threat by reducing the difficulty of items administered via a computer‐adaptive version of the Graduate Record Examinations General Test; and (b) the generalizability of these findings for Black students as well as women, and for verbal as well as quantitative sections of the test. Standard and easier versions of the test, and measures of stereotype threat and possible symptoms or sequelae of stereotype threat were administered to students bound for graduate school or already there. Reducing test difficulty did not have any differential effects on test performance or on explicit indexes of stereotype threat for White and Black students, and for men and women, that were statistically and practically significant. However, such effects did occur for some symptoms or sequelae, mainly for White students and women.     

Stereotype Threat,Inquiring About Test Takers' Ethnicity and Gender,and Standardized Test Performance1

Steele and Aronson (1995) found that the performance of Black research participants on ability test items portrayed as a problem‐solving task, in laboratory experiments, was affected adversely when they were asked about their ethnicity. This outcome was attributed to stereotype threat: Performance was disrupted by participants' concerns about fulfilling the negative stereotype concerning Black people's intellectual ability. The present field experiments extended that research to other ethnic groups and to males and females taking operational tests. The experiments evaluated the effects of inquiring about ethnicity and gender on the performance of students taking 2 standardized tests—the Advanced Placement Calculus AB Examination, and the Computerized Placement Tests—in actual test administrations. This inquiry did not have any effects on the test performance of Black, female, or other subgroups of students that were both statistically and practically significant.     

Paying the Way: The Ticket to Gender Equality in Sports

Past research shows that consumers tend to equate higher prices with higher value. However, it remains unclear whether consumers of athletic events follow the predictions of equity theory when attributing value to particular teams. We conducted 3 studies to investigate the existence and consequences of a disparity between men's and women's college basketball ticket prices. In Study 1, a survey of 303 NCAA Division I programs demonstrated that the gender of a basketball team is a primary indicator of the price of a ticket, such that women's tickets are significantly less expensive than men's tickets nationwide, even after controlling for a number of contextual factors (e.g., win–loss records, size of the schools). Consistent with equity theory, Studies 2 and 3 revealed that such a price disparity can result in lower evaluation of women's teams than men's. These findings indicate a need to consider the costs and benefits of maintaining differences in ticket prices within a context of gender inequity.     

Mechanism, Truth, and Penrose's New Argument

Sections 3.16 and 3.23 of Roger Penrose's Shadows of the mind (Oxford, Oxford University Press, 1994) contain a subtle and intriguing new argument against mechanism, the thesis that the human mind can be accurately modeled by a Turing machine. The argument, based on the incompleteness theorem, is designed to meet standard objections to the original Lucas–Penrose formulations. The new argument, however, seems to invoke an unrestricted truth predicate (and an unrestricted knowability predicate). If so, its premises are inconsistent. The usual ways of restricting the predicates either invalidate Penrose's reasoning or require presuppositions that the mechanist can reject.     

Systemic family therapy can be manualized: research process and findings

Determining the efficacy of therapeutic interventions is becoming an increasing political and ethical necessity. Comparative therapeutic outcome trials are most powerful when there is a precise specification, or manualization, of the forms that therapies took. Manuals have begun to be developed for structural/behavioural family therapy and couple therapy. The development of these manuals is often reliant on experts' self-report, rather than a systematic analysis of the therapeutic process as it happens. This can limit their validity and applicability to standard clinical practice. In addition, no manuals exist which reflect less structured forms of family therapy aimed at incorporating systemic, postmodern and narrative frameworks. The feasibility of producing a workable manual that reflects the fluidity of such practices has been questioned.
A research project to systematically create and test such a manual is reported. Multiple data sources and research methods, primarily qualitative, were applied to generate a rich specification of the therapy. In reporting these results the contents of various aspects of the final manual are indicated. Procedures to ensure that the prescribed practice is consistent with a widely used approach to systemic family therapy are also described.
The manual will be an important tool for outcome research and therapeutic practice. The account of the research process should be helpful to researchers engaged in constructing a manual for other models of family therapy based on a rigorous analysis of actual practice. The manual itself is available for use by outcome researchers who wish to evaluate this widely used form of systemic family therapy.
