Subadditivity in Memory for Personal Events

Abstract—People's subjective probability judgments of external events are often subadditive (i.e., the probability estimates of component parts of a single event sum to greater than one)—a clear violation of the extensional nature of probability theory. We show that people's frequency judgments of personal events can also be subadditive. We found subadditivity even when component events made up a proper subset of a wider composite event. Our findings imply that the somewhat arbitrary choice of the specificity with which questions are asked can produce widely different reports for the same composite events.     

Gender,Race, and Performance Expectations of College Students

Women often have low performance expectations for themselves but expect other women to succeed. We found minority students think not only that they will do worse than other minority group members, but also that their group will do poorly. Low individual and group success expectations make the results for minorities doubly troubling.     

Substance Use and Psychological Adjustment in Homeless Adolescents: A Test of Three Models

Three models of adolescent substance use, the deviance-prone, affect-regulation, and normative development models, were assessed regarding their ability to predict the substance use of a high-risk homeless adolescent sample with high rates of deviance, depression, and substance use. Hierarchical multiple regression analyses that included tests for curvilinear and gender interaction effects were performed. Results supported the deviance-prone model most strongly, with delinquency but not aggressive behavior predicting substance use. The affect-regulation model received support for females but not for males. With respect to the normative development model, results did not indicate that moderate substance users were better off than abstainers in terms of negative affect or interpersonal relationships.     

Spatial and relational frameworks for free recall in young and older adults

Previous studies have demonstrated that older adults can use visually distinctive cues to enhance their spatial memory performance and their recall of the identities of items located in space. Other research has shown that older adults can also use relational information to enhance recall. The relationship between relational and visuospatial support for memory across the adult lifespan is complex and has been little explored. In the present study, this relationship was examined in tasks that measured free recall for item sets possessing different degrees of visuospatial and relational support for recall. It was predicted that both types of support would enhance older adult recall relative to that of the young, and that the two types of support would synergize. The results were generally consistent with these predictions. These findings show that older adults can use relatively simple relational or visuospatial support systems to enhance free recall significantly. This research was supported by Grant AGI 1605, National Institute on Aging.     

Generative Concern, Political Commitment, and Charitable Actions

The implications of psychosocial generativity (Erikson, 1950) for understanding contemporary politics were explored. Study 1 replicated, in two samples, previous findings that generativity concerns are related to a variety of political activities, including the expenditure of time and money in support of political organizations. Using path analyses, Study 2 extended these findings and demonstrated how midlife generativity concerns interacted with political orientation and interest in politics to produce stronger relationships with giving. These findings suggest that people view the political arena as one important way to improve society and thereby manifest cultural generativity. Although focusing on the domain of politics, these studies highlight the complexity of generativity as a construct; broad concerns with generativity operate within the context of ideological commitments to produce greater levels of generative activity.     

Evaluating a more cost-efficient alternative to providing in-home feedback to parents: the use of spousal feedback.

We evaluated the contribution of spousal feedback to a parent education curriculum designed for parents of children with autism. A modified multiple baseline design across 3 husband-and-wife dyads was used to examine the effects of teaching parents to give each other feedback on their teaching performance. For 5 of 6 participants, improvement in teaching performance occurred following didactic presentations. However, additional improvement was observed for 5 participants when the spousal feedback component was implemented.     

Psychological Differential Diagnosis: Alternatives to the DSM System

This article discusses the question of diagnosis of mental disorders and argues for the development of alternatives to the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders. A selected review of this issue is presented along with various alternative conceptions of psychopathology. It is suggested that the categorical and medical orientation of the DSM do not adequately describe psychological processes. It is recommended that Psychology and other health care disciplines, advance alternative conceptions and models of psychological disturbance to educate the public and guide further scientific inquiry.     

Agricultural research organizations: The assessment and improvement of performance

Public sector national agricultural research organizations (NARO)s are confronting the need to demonstrate performance, accountability, and results to maintain support and funding from investors. Current evaluation practices in NAROs are not performance oriented, nor are they applied at the organization level. A performance assessment system for NAROs is presented that integrates productivity and outcome evaluation with the assessment of key management activities influencing research outputs and impact. The system allows managers to record output levels over time and identify management weaknesses.     

Satisfaction With Subordinates: A Neglected Research Issue Concerning Supervisors1

Satisfaction with subordinates, a relatively neglected facet of job satisfaction, was examined via questionnaires administered to both a sample of 37 retail store supervisors and a second sample of 58 bank supervisors regarding 274 of their subordinates. Functional relationships between supervisors and subordinates, in which subordinates help get things done in the workplace, were related to satisfaction with subordinates even after entity relationships (similarity between supervisors and subordinates on biodata and values) were controlled.     

Women and “body-isms” in television beer commercials

Research on women in print advertisements has shown that pictures of women's bodies and body parts (body-isms) appear more often than pictures of men's bodies. Men's faces (face-isms) are photographed more often than their bodies. This present study is the first to confirm this finding for television commercials. Results showed that men appear twice as often as women in beer commercials. The body-isms of women significantly outnumbered the body-isms of men. Women also appeared in swimwear more often than men, thus increasing the photo opportunities for body-isms. This study raises concerns about the dehumanizing influence of these images in beer commercials, and their association with alcohol use and the violence in the televised sporting events during which beer commercials are frequently aired.
