Collaborating careers: The differential effects of race

Male and female black undergraduates enrolled in Introductory Psychology and Human Development courses at a predominantly black university responded to five stories about married black physicians whose total income was greatest, respectively, when the husband cared for the children (Story 1), the wife cared for the children (Story 2), either spouse cared for them (Story 3), the wife earned more than the husband (Story 4), or the husband earned more than the wife (Story 5). In contrast to the results of a study completed at a predominantly white university, black females favored maternal child care even when, as a result, the family income was reduced and had significantly less of a preference for higher relative salary for the wife than did females in the study at a predominantly white university; although black males preferred maternal child care in Story 2 and Story 3, the preference was significantly less than that of males in the study at a predominantly white university. The results were discussed in terms of their relevance to collaborating career patterns among middle-class black families.     

Short-term proactive inhibition in the pigeon

Proactive inhibition in the pigeon was studied using a delayed-color-matching-to-sample task, with and without presentation of stimuli prior to the sample. Interference theory predicts that, relative to control performance, the disruptive effects of a prior stimulus should increase over a retention interval, while decay theory predicts that such disruptive effects should decrease over time. Results supported decay theory when performance was at a low level and interference theory when performance was at a high level. With performance at an intermediate level, parallel functions were obtained, an outcome supporting neither theory. It was concluded that the results supporting interference and decay theories were artifactually produced by floor and ceilling effects, respectively, and it was suggested that the results of earlier experiments using the present paradigm may well have been influenced by similar artifacts. Inserting a nondisruptive stimulus between a prior disruptive stimulus and the sample virtually eliminated the disruptive effects of the prior stimulus when tested immediately, but not when tested after 1 sec. The results of the present experiments and related findings can best be explained by either a modified decay theory (Grant, D. S. Proactive interference in pigeon short-term memory. Journal of Experimental Psychology: Animal Behavior Processes 1975, 104, 207–220) or a modified temporal discrimination theory.     

Covariation and temporal contiguity as principles of causal inference in young children

Four- to seven-year-old children observed a simple physical effect which could be attributed to either a consistent but noncontiguous covariate or a contiguous but inconsistent covariate. When there was a physical rationale for the temporal delay between covariate and effect, children attributed the effect to the consistent but noncontiguous covariate. In the absence of such a rationale, they attributed the effect to the contiguous but inconsistent covariate. It was concluded that neither consistent covariation nor strict temporal contiguity were essential aspects of causal inference for these children.     

Solidarity and the New Inequality

Economists now have the data to generate a high‐resolution picture of the economic inequalities within the very top fractions of income and wealth and between the top‐most fractions and others that have emerged since the early 1980s. I shall refer to these inequalities collectively as “the new inequality.” I argue that the moral value of solidarity can be used to raise pointed moral questions about the new inequality. In most cases, however, I shall raise such questions without answering them. For I contend that solidarity functions more usefully as part of an articulate hermeneutic of suspicion—that is, as a central element in skepticism about economic inequalities and their justifications. Seeing that it functions in this way, we can see one contribution religious ethics makes to an inquiry into the new inequality.
