Images of midlife development among young,middle-aged,and older adults

This study examined patterns of perceived change across adulthood in a sample of 121 young (M age=19.8 years), middle-aged (M age=47.9 years) and older (M age=74.6 years) adults. Subjects rated amount of stress in life domains, salience of life course issues, and nature of personal attributes for young, middle-aged, and older targets. Seven prototypical patterns of perceived change were found. Midlife was seen as a period with many responsibilities, increased stress in several domains, and little time for leisure, but also as a peak in competence, ability to handle stress, sense of control, productivity, and social responsibility. The findings are discussed in terms of losses, which were seen primarily in the physical realm, and gains, which were mainly seen in the psychological and social realms.     

Rethinking the gender identity crossover hypothesis: A test of a new model

Both self-report and projective assessment techniques were used to examine whether there exists a gender identity crossover at midlife such that men develop a communal or affiliative orientation and women become more interested in agency and power. A sample of 150 predominantly Caucasian men and women ages 24–84 were divided into three age groups for comparison: (1) young (ages 20–39); (2) middle-aged (ages 40–65); and (3) old (ages 66–84). Measures included six pictures from the Thematic Apperception Test, which were coded for achievement, power, intimacy, and affiliation needs, and the Goldberg 50-Bipolar, from which items were selected to derive agency and communion scales. Middle-aged men were lower in the need for power and higher in the need for affiliation than were younger men; there were no age differences in self attributions of agency and communion. Results are discussed in terms of the traditionality of the men and the nontraditionality of the women with respect to work and family roles.This research was supported in part by grants to Margie Lachman from the John D. and Catherine T.

Developmental changes in inspection time: what a difference a year makes

This paper provides a partial replication and extension of a classic longitudinal study by Nettelbeck and Wilson [J. Exp. Child Psychol. 40 (1985) 1] that compared the relative influence of maturation and task experience on developmental changes in inspection time (IT). In the study reported in this paper 226 children aged between 6 and 9 were tested on an IT task in Year 1 and immediately retested to assess the importance of task familiarity. They were also retested 1 year and 2 years later. Counter to Nettelbeck and Wilson's conclusion, analyses of these data comparing the relative difference made by age maturation and by task experience revealed that task experience has a much bigger effect on children's IT than maturation. The implications of this for wider theoretical interpretations of the relationship between IT and development are discussed.     

Differential age effects in load-dependent memory processing

This study examined differential age effects in a young and a middle-aged sample by means of a sequential n-back task with increasing memory load. Participants processed two streams of stimuli either separately as a single task, or simultaneously as a dual task. We investigated age effects as a function of memory load in both the single and the dual-task version. In accuracy, we observed differential age effects as a function of load, which were more prominent in the dual-compared to the single-task versions. That is, middle-aged participants performed poorer than young adults in the dual-task conditions, suggesting that early age-related changes become especially apparent in conditions where task coordination and resource sharing come into play. Regarding latencies, we observed no differential age effect, which we believe is due to characteristics of the sequential n-back task.     

Adult Age Differences in Dual Information Processes: Implications for the Role of Affective and Deliberative Processes in Older Adults' Decision Making

ABSTRACT— Age differences in affective/experiential and deliberative processes have important theoretical implications for judgment and decision theory and important pragmatic implications for older-adult decision making. Age-related declines in the efficiency of deliberative processes predict poorer-quality decisions as we age. However, age-related adaptive processes, including motivated selectivity in the use of deliberative capacity, an increased focus on emotional goals, and greater experience, predict better or worse decisions for older adults depending on the situation. The aim of the current review is to examine adult age differences in affective and deliberative information processes in order to understand their potential impact on judgments and decisions. We review evidence for the role of these dual processes in judgment and decision making and then review two representative life-span perspectives (based on aging-related changes to cognitive or motivational processes) on the interplay between these processes. We present relevant predictions for older-adult decisions and make note of contradictions and gaps that currently exist in the literature. Finally, we review the sparse evidence about age differences in decision making and how theories and findings regarding dual processes could be applied to decision theory and decision aiding. In particular, we focus on prospect theory ( Kahneman & Tversky, 1979 ) and how prospect theory and theories regarding age differences in information processing can inform one another.     

Psychosocial factors in outcomes of heart surgery: the impact of religious involvement and depressive symptoms.

This article reports a prospective study of religiousness and recovery from heart surgery. Religiousness and other psychosocial factors were assessed in 142 patients about a week prior to surgery. Those with stronger religious beliefs subsequently had fewer complications and shorter hospital stays, the former effect mediating the latter. Attendance at religious services was unrelated to complications but predicted longer hospitalizations. Prayer was not related to recovery. Depressive symptoms were associated with longer hospital stays. Dispositional optimism, trait hostility, and social support were unrelated to outcomes. Effects of religious beliefs and attendance were stronger among women than men and were independent of biomedical and other psychosocial predictors. These findings encourage further examination of differential health effects of the various elements of religiousness.     

Should I stay or should I go?: Penalties for briefly de-prioritizing work or childcare

We examined penalties against individuals who temporarily de-prioritize their employee or parenting role. Experiment 1 (N = 488) utilized vignettes depicting a mother/father who briefly left their child with a babysitter to engage in work/self-care/did not leave (control). Both mothers and fathers were viewed as less parentally competent, likeable, dedicated to their family (and putting their child at greater risk) when they very briefly de-prioritized their caregiving role by leaving their child for either reason, relative to controls. Experiment 2 (N = 494) utilized vignettes depicting a female/male employee who briefly left work to engage in childcare/self-care/did not leave (control). Both male and female employees were rated as less professionally competent, likeable, dedicated to their work and deserving of organizational rewards (and more deserving of organizational penalties, and putting their organization at greater risk) when they very briefly de-prioritized their employee role by leaving work for either reason, compared to controls. However, employees who left for self-care were viewed more negatively than those who left to engage in childcare. Unexpectedly, results did not reveal target gender differences; they were also largely unaffected by participant gender. This suggests that parents and employees face penalties when they must de-prioritize either of these important roles for even very short periods. Implications for well-being, work-life balance, and productivity are discussed.
