A psychometric analysis of the Personal Attributes Questionnaire

The psychometric properties of the Personal Attributes Questionnaire were examined in independent samples of male and female high school students, college students, and adults. In each of the six samples a two-factor structure (masculinity/instrumentality and femininity/expressivity) paralleling the empirically derived scales was found. Additional factor analyses of negative masculine and feminine traits were reported. Discriminant analyses revealed highly significant differentiation between the sexes. The reliabilities (Cronbach alpha) of the unit-weighted scales in each sample were also satisfactory.Support for this research was provided by NASA Grant NSG 2065 (Robert L.

Resolving Ethical Dilemmas in Management: Experimental Investigations of Values, Accountability, and Choice

Hypotheses regarding the effects of personal values and accountability on the resolution of ethical dilemmas in management were formulated and tested experimentally with a sample of 135 M.B.A. students. Personal values were found to be related to how subjects chose to resolve an ethical dilemma presented to them; but, as expected, this relationship did not hold when subjects were made to feel accountable to another for their choices. Accountability, unexpectedly, however, did not have a main effect on choices. This lack of an effect tentatively was attributed to the inexplicitness of the accountability manipulations. In a second and third experiment, support for the importance of explicitness in accountability research was obtained. The theoretical and practical implications of the findings from all three experiments were discussed.     

Relations between neonatal states and 8-month developmental outcome in preterm infants

This study investigated longitudinal relations between measures of neonatal state behavior and developmental outcome in a sample of preterm infants (N = 16). Results indicate that irritability/reactivity in the neonatal period is positively associated with Bayley scores and exploratory play at 8 months. Conversely, neonatal alertness was not associated with these developmental measures. These preliminary findings, based on a small sample, are discussed in the context of preterm function.     

Age-related increases in the effects of automatic semantic activation.

Automatic semantic activation was assessed in a version of the flanker task, in which nominally irrelevant words were presented above and below a target word. The category membership of the flanking word was consistent, inconsistent, or neutral with respect to the target word. Older adults showed greater inhibition and equivalent facilitation in the time taken to classify the target words than did younger adults in 2 of 3 experiments, in contrast to previous findings. The present results are generally consistent with 3 dominant perspectives in cognitive aging: the complexity hypothesis, environmental support, and the inhibition-deficit view. Manipulation of the overall magnitude of the flanker effect produced results most consistent with the inhibition-deficit view that older adults are less able to inhibit automatic processes than are younger adults. Some problems with the inhibition-deficit view are also discussed.     

Effects of adult age on structural and operational capacities in working memory

Eight experiments were conducted in which young adults and older adults were asked to report the latest value of 1 of several continuously changing numeric or spatial variables. Accuracy of reporting the current value of the target variable was lower with increases in the number of potentially relevant variables and with increases in the number of required processing operations. Young and older adults exhibited similar effects of the number of potentially relevant variables (hypothesized to be sensitive to the structural capacity of working memory) and of the number of required processing operations (hypothesized to be sensitive to the operational capacity of working memory), but older adults were generally less accurate than young adults.     

Confidence depends on level of aggregation

The credible intervals that people set around their point estimates are typically too narrow (cf. Lichtenstein, Fischhoff, & Phillips, 1982). That is, a set of many such intervals does not contain the actual values of the criterion variables as often as it should given the probability assigned to this event for each estimate. The typical interpretation of such data is that people are overconfident about the accuracy of their judgments. This paper presents data from two studies showing the typical levels of overconfidence for individual estimates of unknown quantities. However, data from the same subjects on a different measure of confidence for the same items, their own global assessment for the set of multiple estimates as a whole, showed significantly lower levels of confidence and overconfidence than their average individual assessment for items in the set. It is argued that the event and global assessments of judgment quality are fundamentally different and are affected by unique psychological processes. Finally, we discuss the implications of a difference between confidence in single and multiple estimates for confidence research and theory.
