Effort Effect: An Artifact of Effort-Produced Partial Responses?

The Psychological Record - It was previously found (Arm us, 1986, 1988, 1990) that greater response effort requirements led to a greater percentage of short (< 1 s) interresponse times...     

Social Trust and Value Change: The Decline of Social Capital in American Youth, 1976–1995

Given the importance that generalized social trust plays in various theories of American society, recent evidence of its low levels among younger people portends ominous changes in American civic life. Using survey data collected from high school seniors over the last 20 years, this paper examines the origins of social trust among young people and the causes of change in beliefs about trust over time. Such changes could not be accounted for by the explanations for declining trust offered in other accounts of social capital. An alternative explanation, based on the theoretical accounts of Alexis de Tocqueville and Emile Durkheim, is that materialistic values may be undermining young people's views about the trustworthiness of others. Both aggregate time series correlations and an individual-level model show that the rapid rise of materialistic value orientations that occurred among American youth in the 1970s and 1980s severely eroded levels of social trust. The paper concludes with some observations about the likely trajectory of American democracy, given the kinds of trends observed in the youth data.     

Between adolescents and aging grandparents: Midlife concerns of adults in the “Sandwich generation”

This study examined whether the midlife transition of men and women in the “sandwich generation” was related to their 15- to 19-year-old adolescent's psychosocial development and their relationships with their own aging parents (i.e., the grandparents). One hundred eighty-six (186) respondents representing adolescents, mothers, and fathers from 62 families completed questionnaires that assessed adolescents' psychological autonomy and involvement in adult-type roles, adults' midlife transition and marital quality, and adults' relationships with their aging parents. Analyses conducted by domain revealed that women reported greater concerns with midlife issues when their adolescents demonstrated fewer signs of psychological autonomy and involvement in adult-type roles whereas men reported more intense midlife concerns when they experienced more strain in their relations with their own parents. When adolescent, grandparent, and marital factors were considered conjointly, the results indicated that women's level of midlife concerns was still related to their adolescents' development, but men's level of concerns was most strongly related to their satisfaction with the quality of their marriages. The discussion focuses on adult women's and men's experience of the midlife transition in relation to adolescents' development, parents' relationships with aging grandparents, and marital quality.     

Psychological Science in Australia

This paper is a brief account of the Australian Strategic Review of the Psychology Discipline and its Research. Issues discussed include Australia's contribution to world research in psychological science, research funding, the age and qualifications of researchers, the social and economic benefits arising from the applications of research outcomes, multidisciplinary issues, the role of psychology in industry, links between the discipline and the profession of psychology, professional training, cross-cultural issues, and educational issues. Priorities for development of research and postgraduate training are identified, and include human factors and other areas related to technological change, clinical psychology with particular attention to health psychology, industrial and organizational psychology, and neuroscience and physiological psychology.     

Unemployment and youth: A longitudinal study

In order to examine further some of the effects of the experience of unemployment on school leavers of both sexes, measures of self-esteem, depression and locus of control were administered to 57 males and 56 females prior to their leaving school (Time 1), and again 5 months later (Time 2). At Time 2, the subjects had either returned to school, found employment, or were unemployed. The longitudinal nature of the design enabled statements about causality to be made. Group and sex differences at Time 1 and Time 2 were analysed using discriminant analysis and factorial analysis of variance. Results showed a clear effect of the experience of unemployment on the unempoyed, with the unemployed group increasing their scores on depression and external locus of control, and decreasing their self-esteem scores. Sex differences for depression and self-esteem were found at Time 1, and for depression only at Time 2. Significant employment group x sex interactions were found for self-esteem and locus of control at Time 2.     

The dependence of semantic relatedness effects upon prime processing

The semantic relationship between a prime and a target word has been shown to affect the speed at which the target word is processed. This series of experiments investigated how the semantic priming effect is influenced by the nature of the task performed on the prime word. Subjects were asked to perform either a naming or a letter-search task on the prime word and either a lexical-decision or color-naming task on the target word. When the primes were named, response times for the target words were facilitated in the lexical-decision task and inhibited in the color-naming task. However, these effects were eliminated or reduced to an insignificant level when the primes were searched for letters. We suggest that in order to produce the usual priming effect, the primes have to be processed for meaning rather than probed for constituents.     

Family interactions of assaultive adolescents,stealers, and nondelinquents

Eleven adolescent chronic offenders apprehended for assaultive crimes in the community were observed in their family homes. This group was matched with 11 adolescents apprehended for stealing and with 11 adolescents with no court contact. Assaultive adolescents, unlike their controls, ranked significantly higher among their own family members in terms of their total aversive behavior in the family home. The results support the notion that assaultive adolescents are more involved with fighting with their siblings in the family home and consequently have had more practice in fighting than their controls, thereby preparing them for assaultive behavior in the community. Assaultive adolescents had more female siblings than male siblings, whereas nondelinquent adolescents had more male than female siblings.     

Comparisons of stimulus learning and response learning in a punishment situation

These experiments use a procedure in which a rat is trained to make two topographically distinct responses on a single manipulandum, and then one of the responses is punished. Differential suppression of the punished response is taken as evidence of response learning, whereas the common suppression of both responses is attributed to stimulus learning or to general and nonassociative factors. Thus, this procedure begins the experimental separation of animals learning about the consequences of their behavior and animals learning what happens in a particular environment. A further separation is effected by using two such manipulanda; this procedure begins to distinguish between stimulus learning about the manipulandum and the more gereral factors that cause suppression. Some parameters affecting the relative importance of stimulus learning and response learning are examined.
