Why do males and females differ? Children's beliefs about sex differences

The present paper focuses on children's beliefs about sex differences and how these are related to age and gender. Seven, ten, and fifteen year olds (N=427) were asked to give explanations for their beliefs about sex differences. In strong agreement with previous research and the cognitive-developmental theoretical framework, marked age differences were found: younger children were more likely than older children to emphasize biological and physical factors. Significant gender differences were also found, especially for 15 year olds. Girls were much more likely to attribute sex differences to social factors, and boys to biological factors. These gender differences were interpreted as being indicative of different life experiences of males and females, with females being more likely to have experienced conflicts between their own values about sex-role behavior and those of society. Findings were also interpreted as being consistent with the recent emphasis on gender schema. Nevertheless, it was argued that theories of gender schema need to take more account of content—of the beliefs that people hold about sex roles—and, in particular, that more attention be given to exploring gender differences in beliefs.     

No aging bias favoring memory for positive material: evidence from a heterogeneity-homogeneity list paradigm using emotionally toned words

Some authors argue for a memory advantage of older adults for positively toned material. To investigate the contribution of selective processing to a positivity effect, the authors investigated young (n = 72, aged 18 to 31) and older (n = 72, aged 64 to 75) adults' memory for emotionally toned words using a multitrial paradigm that compares performance for heterogeneous (mixed valence) and homogeneous (single valence) lists. Regarding the age comparison, there was no evidence for an aging bias favoring positive material. Moreover, older adults' memory was less affected by emotion-based processing prioritization. Although there was no support for age-specific processing biases in memory for emotionally toned words, the findings are consistent with proposals that negative information receives processing priority in some contexts. Possible limits to the generalizability of the present findings (e.g., to nonverbal material) are discussed.     

Resources and life-management strategies as determinants of successful aging: on the protective effect of selection, optimization, and compensation

In this research, the authors investigated the specific and shared impact of personal resources and selection, optimization, and compensation (SOC) life-management strategies (A. M. Freund & P. B. Baltes, 2002) on subjective well-being. Life-management strategies were expected to be most relevant when resources were constrained, particularly in very old age. In Study 1 (N=156, 71-91 years), age-differential predictive patterns supported this assumption: Young-old individuals' well-being was predicted independently by resources and SOC, whereas SOC buffered the effect of restricted resources in old-old individuals. Study 2 replicated the findings longitudinally with resource-poor and resource-rich older individuals (N=42). In both studies, specific SOC strategies were differentially adaptive. Results confirm that resources are important determinants of well-being but that life-management strategies have a considerable protective effect with limited resources.     

When time is running out: changes in positive future perception and their relationships to changes in well-being in old age

How optimistically individuals view their future and what they expect from it has often been studied in younger adults. Less attention has been paid to future perceptions in older adults whose future is temporally limited. Using longitudinal data from the Berlin Aging Study, the authors examined whether future orientation and optimism change in older adults (70-104 years) and whether changes in future perception precede changes in well-being. With advancing age participants reported fewer future plans and less optimism. Those changes were related to changes in well-being with partial support for a lead-lag relationship.     

Characteristics for 200 words rated by young and older adults: Age-dependent evaluations of German adjectives (AGE)

We describe the Age-Dependent Evaluations of German Adjectives (AGE). This database contains ratings for 200 German adjectives by young and older adults (general word-rating study) and graduate students (self-other relevance study). Words were rated on emotion-relevant (valence, arousal, and control) and memory-relevant (imagery) characteristics. In addition, adjectives were evaluated for self-relevance (Does this attribute describe you?), age relevance (Is this attribute typical for young or for older adults?), and self-other relevance (Is this attribute more relevant for the possessor or for other persons?). These ratings are included in the AGE database as a resource tool for experiments on word material. Our comparisons of young and older adults’ evaluations revealed similarities but also significant mean-level differences for a large number of adjectives, especially on the valence dimension. This highlights the importance of age in the perception of emotional words. Data for all the words are archived at www.psychonomic.org/archive/.     

Sex differences in children's group embedded figures test performance

Despite the fact that sex differences in field dependence/independence have been a fairly constant feature in studies employing adults, doubt surrounds the status of similar sex differences in childhood. Several attempts have been made to explain these findings, the most popular being that group Embedded Figures Tests do not tap sex differences. A simpler explanation is that large enough Ns have not been employed in past research to allow the small sex difference present in childhood to emerge as a statistically significant phenomenon. This explanation is supported by the results of the present study which employed 1200 children and was able to demonstrate a significant sex difference at both 8 and 11 yr using the Children's Group Embedded Figures Test.     

Predicting children’s liking of school from their peer relationships

Prior studies have established that children’s peer relationships and school adjustment are associated. The main aims of the current study were to test if four measures of peer relationships (Peer Acceptance, Presence/Absence of Best Friend, Number of Friends, and Perceived Peer Support) could predict School Liking concurrently and longitudinally across a 6 month period, and if gender moderated any of those associations. An opportunistic sample of girls and boys (N = 429 at Time 1 and N = 214 at Time 2) was drawn from 10 junior schools in the UK. A short-term longitudinal survey design was employed in which self- and peer-report measures were administered in small groups at Time 1 (November/December) and then again at Time 2 (May/June) of the same academic year. Concurrently, all four peer relationship variables emerged as significant non-unique predictors (i.e. not controlling for variance shared among the predictors) of School Liking; Peer Acceptance and Perceived Peer Support emerged as significant unique predictors (i.e. after controlling for variance shared among the predictors) of School Liking; the set of four peer relationship variables together accounted for a significant amount of variance in School Liking; and gender moderated the association between Peer Acceptance and School Liking. Longitudinally, Peer Acceptance was a significant unique predictor of changes in School Liking. This study adds to the literature by providing evidence of which specific peer relationships predict School Liking, and they support the call for interventions to enhance those relationships.     

Dynamic links between memory and functional limitations in old age: longitudinal evidence for age-based structural dynamics from the AHEAD study

This study examined competing substantive hypotheses about dynamic (i.e., time-ordered) links between memory and functional limitations in old age. We applied the Bivariate Dual Change Score Model to 13-year longitudinal data from the Asset and Health Dynamics Among the Oldest Old Study (AHEAD; N = 6,990; ages 70 - 95). Results revealed that better memory predicted shallower increases in functional limitations. Little evidence was found for the opposite direction that functional limitations predict ensuing changes in memory. Spline models indicated that dynamic associations between memory and functional limitations were substantively similar between participants aged 70-79 and those aged 80-95. Potential covariates (gender, education, health conditions, and depressive symptoms) did not account for these differential lead-lag associations. Applying a multivariate approach, our results suggest that late-life developments in two key components of successful aging are intrinsically interrelated. Our discussion focuses on possible mechanisms why cognitive functioning may serve as a source of age-related changes in health both among the young-old and the old-old.
