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.     

Population sex differences in IQ at age 11: the Scottish mental survey 1932

There is uncertainty whether the sexes differ with respect to their mean levels and variabilities in mental ability test scores. Here we describe the cognitive ability distribution in 80,000+ children—almost everyone born in Scotland in 1921—tested at age 11 in 1932. There were no significant mean differences in cognitive test scores between boys and girls, but there was a highly significant difference in their standard deviations (P<.001). Boys were over-represented at the low and high extremes of cognitive ability. These findings, the first to be presented from a whole population, might in part explain such cognitive outcomes as the slight excess of men achieving first class university degrees, and the excess of males with learning difficulties.     

Self, Other, Positive, and Negative Affect Scales of the Self-Confrontation Method: factorial structure and unidimensionality

In the self-confrontation method, the rows of a grid consist of valuations (i.e. summaries of important personal narratives), while the columns contain affects grouped into four scales (see title). These affects (varying from 16 to 30) are rated on a 0–5 scale of intensity, resulting in an affect profile for each valuation. Principal components analysis on the affect profiles of a client sample, using a list of 30 affects, yielded a 3-factor solution, with 2 unipolar and 1 bipolar factor, in accordance with the four scales. On the basis of this analysis, a list of 24 affects was derived with six affects per scale. This list was then applied to a student sample to cross-validate the results. Unidimensionality of the four scales was found at the level of single grids, and across both client and student samples. It was concluded that the four scales of the 24-affect list appeared to be psychometrically sound and optimally suited for use in research and practice.     

Negative representations of the self/spouse and marital distress

The link between marital distress and negative representations of both the self and the spouse was examined with data from an initial sample of 538 married couples studied over the first four years of marriage (Study 1) and 98 of these couples studied in their tenth year of marriage (Study 2). Findings from Study 1 indicated that, for both husbands and wives, representations of the self and representations of the spouse accounted for unique variability in distress. Across spouses, representations of the spouse accounted for more of the variability in distress than did representations of the self. Cross–spouse effects were especially pronounced for husbands such that their distress was linked to wives’ representations. Findings from Study 2 with self/spouse measures anchored to the marital context replicated this pattern. Findings support the view that marital distress is uniquely influenced by models of both the self and the spouse, that representations of the self and the spouse are dynamic relationship schemas, that models of the self and the spouse can be meaningfully assessed within the marital context, and that negative representations of the spouse—particularly those of wives—are especially diagnostic of marital distress.
