Age and gender differences in adolescent worry

The purpose of the present study was to explore gender and age differences in adolescent worry. High school students filled out measures of worry, negative problem orientation, intolerance of uncertainty, and general mental health. Girls and boys of different ages were then compared and the relationships between gender, beliefs about worry, intolerance of uncertainty, negative problem orientation and mental health were also examined. Boys reported greater negative problem orientation and intolerance of uncertainty while girls reported more positive beliefs about worry. Findings also revealed certain age trends, indicating that the variables under study may be under the influence of developmental tasks. Regression analysis was performed and positive beliefs about worry emerged as a significant predictor of worry in both sexes. Positive beliefs about worry and negative problem orientation appear to be the key processes in adolescent anxiety and depression.     

Ethnic and racial differences in body size perception and satisfaction

Body dissatisfaction in women in the United States is common. We explored how women from various racial and ethnic groups used figural stimuli by exploring differences in current and preferred silhouette, and their discrepancy. We surveyed 4023 women aged 25–45 in an online investigation. Participants were identified using a national quota-sampling procedure. Asian women chose a smaller silhouette to represent their current body size, which did not remain significant after adjusting for self-reported BMI. After controlling for BMI, African American women selected a smaller silhouette than White women to represent their current size. Both African American and women reporting “Other” race preferred larger silhouettes than White women even after controlling for BMI. The discrepancy score revealed lower body dissatisfaction among African American than White women. Understanding factors that promote body satisfaction differentially across racial and ethnic groups could become a tool in appropriately tailored interventions designed to prevent eating disorders.     

Longitudinal associations between television viewing patterns and adolescent body satisfaction

This study addressed profiles of adolescent television use and associations between television viewing profiles and the development of body satisfaction. A sample of 841 adolescent boys and girls, ages 11-17, was recruited for participation in a longitudinal study of adolescent media use. Prior research established eight adolescent television profiles among this sample, reflecting unique patterns of consumption of certain genres, character types, and themes (e.g., romance). This study examined whether an adolescent's television profile predicted Time 2 body satisfaction, after controlling for Time 1 body satisfaction. Among boys, television viewing was unrelated to Time 2 body satisfaction. After controlling for initial body satisfaction, hours spent watching television marginally predicted lower Time 2 body satisfaction among girls. After including television profiles alongside television hours, however, television profile emerged as the stronger predictor. Specifically, a group of girls who watched television frequently and indiscriminately reported the most severe drop in body satisfaction.     

Age differences in choice satisfaction: a positivity effect in decision making

The authors tested the possibility that older adults show a positivity effect in decision making, by giving younger and older adults the opportunity to choose 1 of 4 products and by examining the participants' satisfaction with their choice. The authors considered whether requiring participants to explicitly evaluate the options before making a choice has an effect on age differences in choice satisfaction. Older adults in the evaluation condition listed more positive and fewer negative attributes than did younger adults and were more satisfied with their decisions than were younger adults. There were no age differences among those who did not evaluate options. This evaluation-dependent elevation of satisfaction among older adults was still present when participants were contacted 2 weeks after the experiment. Age did not influence the accuracy with which participants predicted how their satisfaction would change over time.     

Age differences in rereading

Younger and older adults read a series of expository and narrative passages twice in order to answer comprehension questions. Reading time was used to index attentional allocation to word, textbase, and situation model processing and to assess shifts in the allocation policy from the first to the second reading. Older readers' comprehension was at least as good as that of younger readers. Analysis of reading times suggested that for both genres, older adults allocated more attention to situation model features than younger adults did on the first reading, whereas young and old allocated attention similarly to this level of representation on the second reading, suggesting that mature readers may give greater priority to situation model construction when first encountering text. Also, for both genres, older adults showed relatively less facilitation than the young in word-level processing in rereading, suggesting that representation at this level is not as firmly established during reading or decays more quickly for older readers. For narrative texts only, this pattern also obtained for textbase processing. Collectively, these data show that age equivalence in text comprehension at the molar level may be accomplished through different processing routes at the molecular level.     

Age differences in maximization

Studies have shown the existence of inter-individual differences in choice behavior, some people seeking for the best (maximizers) and others for a good enough option (satisficers). Here, we explored whether these inter-individual differences are influenced by aging and common personality traits (i.e., Big Five model). Young (n = 125; 19 years old) and elderly adults (n = 101; 86 years old) completed different scales assessing – among others – maximization and Big Five traits. Our results indicated a greater proportion of maximizers in elderly than in young adults. We also found a minor association between maximization and Big Five traits in both groups. In sum, aging influences choice behavior, but this cannot be explained by changes of common personality traits.     

Dieting behaviors, body shape perceptions, and body satisfaction: cross-cultural differences in Argentinean and Swedish 13-year-olds

This exploratory study represents a cross-cultural effort to examine differences in dieting practices and weight loss attempts, perceived body shape, and body satisfaction between young Argentinean and Swedish adolescents. The study group consisted of 358 Argentinean (193 girls, 165 boys) and 874 Swedish (474 girls, 400 boys) 13-year-olds. A main finding was that Argentinean and Swedish adolescents did not differ on body satisfaction, although girls in both countries displayed greater body dissatisfaction than did boys. Dieting and weight loss attempts were more prevalent among the Argentinean adolescents, especially among girls, and did not appear to depend on overweight or perception of body shape. The samples also differed in their perceptions of body shape and the effect those perceptions had on their body satisfaction, with Swedish adolescents suffering more from negative body shape perceptions.     

Adult attachment and body satisfaction. An exploration of general and specific relationship differences

The relationship between general and specific adult relationship attachment and body satisfaction was examined in a community sample of 133 women. Participants completed measures of body image (body surveillance, body-as-object esteem, and body-as-process satisfaction) and general attachment (anxiety and avoidance) and then were primed for a romantic partner or close friend relationship, after which they completed specific measures of attachment and body satisfaction. General attachment results replicated previous research. Specific attachment results demonstrated distinct differences both from general attachment and between romantic partner attachment and close friend attachment. Attachment independently predicted body satisfaction both for general and close friend measures; however, in romantic relationships, only body surveillance independently contributed to body satisfaction.     

Gender differences in satisfaction with grandparenting

Grandmothers (n = 177) and grandfathers (n = 105) completed mail questionnaires covering demographic and family background, and grandparenting satisfaction and perceived responsibilities (disciplining, caretaking, helping, advising). Grandmothers' satisfaction scores significantly exceeded those of grandfathers, and different variables predicted men's and women's satisfaction scores. Discussion focuses on possible sources of these gender differences, and consequences of these differences for further research.     

Age differences in coping resources and satisfaction with life among middle-aged,young-old,and oldest-old adults

The authors examined age differences in perceived coping resources and satisfaction with life across 3 older-adult age groups (45-64, 65-74, and 75 years and older). The 98 participants represented healthy, socially active, community-residing adults. Group comparisons were made on 12 individual coping scales, and an overall coping resource effectiveness score was computed. No significant differences were found for 11 of the coping resources or for overall coping resource effectiveness. Similar consistencies in life satisfaction were found across the 3 age groups. The findings indicate that (a) for healthy adults, the oldest old cope at least as effectively as their younger counterparts, despite their likelihood of encountering increased levels of stress; and (b) psychologically, old age may be viewed as a time of resilience and fortitude.     

Age differences in memory span

Five-year-olds recalled fewer items than adults in memory-span tasks involving both familiar and unfamiliar faces. This occurred even though the use of rehearsal and recoding strategies was minimized for adults. This residual age difference may be partially accounted for by two further processing limitations in children. The five-year-olds needed more time than adults to name a face (Experiment 1) and to encode a face (Experiment 2). In order to test whether limitations in children's initial recognition and stimulus-identification processes could account for recall performance, Experiment 3 reduced adults' exposure duration in the memory-span task. This led to a drastic reduction in the age difference. Other factors contributing to remaining age differences included adults' adaptability in using various alternative encoding and retrieval strategies which elevated their recall performance.     

Age differences in recognition memory

It is generally believed that short-term memory (STM) performance decreases from maturity to old age, but the present paper questions the generality of this conclusion. The first experiment reported is a short-term recognition probe study—no significant age differences were found in either acquisition or the rate of forgetting. It is suggested that age decrements in STM are limited to situations where attention is divided at input or where the material must be manipulated during storage. Experiment II confirmed previous findings of minimal age losses in secondary memory word recognition. The results of this second study support the conclusion that there is poorer accessibility to stored verbal material with advancing age.     

Age differences in saccadic averaging

Younger and older adults were asked to saccade to an orientation-defined target that was presented alone, with a more central distractor, or with a more peripheral distractor. Both age groups exhibited saccadic averaging that was more pronounced in the central distractor condition, wherein older adults had the larger effect. These results are relevant to questions of oculomotor control and also have implications for the study of age differences in other visually guided behaviors.     

Sex differences in the adolescent brain

Adolescence is a time of increased divergence between males and females in physical characteristics, behavior, and risk for psychopathology. Here we will review data regarding sex differences in brain structure and function during this period of the lifespan. The most consistent sex difference in brain morphometry is the 9–12% larger brain size that has been reported in males. Individual brain regions that have most consistently been reported as different in males and females include the basal ganglia, hippocampus, and amygdala. Diffusion tensor imaging and magnetization transfer imaging studies have also shown sex differences in white matter development during adolescence. Functional imaging studies have shown different patterns of activation without differences in performance, suggesting male and female brains may use slightly different strategies for achieving similar cognitive abilities. Longitudinal studies have shown sex differences in the trajectory of brain development, with females reaching peak values of brain volumes earlier than males. Although compelling, these sex differences are present as group averages and should not be taken as indicative of relative capacities of males or females.     

Age differences in genetic and environmental influences on eating attitudes and behaviors in preadolescent and adolescent female twins

A sample of 680 11- and 602 17-year-old female twins was used to examine (a) age differences in genetic and environmental influences on disordered eating attitudes and behaviors and (b) associations between body mass index (BMI) and eating attitudes and behaviors. Univariate, biometrical model-fitting analyses indicated that 11-year-old twins exhibited less genetic and greater shared environmental influence on eating attitudes and behaviors than 17-year-old twins. Bivariate model-fitting analyses indicated that the relationship between BMI and eating attitudes was mediated primarily by common shared environmental influences in 11-year-old twins and common genetic influences in 17-year-old twins. Nonetheless, the majority of genetic influences on eating attitudes and behaviors in older twins were due to genetic effects that are independent of those operating in BMI.     

Sport participation,body satisfaction and depressive symptoms in adolescence: a moderated-mediation analysis of gender differences

This research aimed to analyse the partial mediating role of body satisfaction in the relationship between sport participation and depressive symptoms, as well as to examine the moderating role of gender in these associations. A cross-sectional study was conducted with a sample of 1810 adolescents aged 13–18 years old who completed self-report measures regarding sport participation, body satisfaction and depressive symptoms. The results indicated that a higher frequency of sport participation was associated with a lower presence of depressive symptoms, both directly and through greater body satisfaction, although gender differences were found in this partial mediation model. It was detected that sport participation had a greater effect on positive body satisfaction among boys, whereas body dissatisfaction indicated a greater presence of depressive symptoms among girls. The results emphasize the need to implement gender-specific programmes to improve psychological adjustment in adolescents by promoting sport practice and body acceptance.     

Sex differences and adolescent depression

This study investigates the role of certain psychosocial variables--sex, age, body image/self-esteem, self-consciousness, stressful life events, and the degree to which an individual identifies with the cultural stereotype of masculinity--as correlates and antecedents to depression in adolescents and explores possible intraindividual mediators of the stress-depression relationship in adolescents. A battery of self-report measures was administered to public high school students in Grades 9-12 in their classrooms at two different times 1 month apart. Female adolescents reported more depressive symptoms, self-consciousness, stressful recent events, feminine attributes, and negative body image and self-esteem; no age effects were obtained. Results suggest a model of adolescent depression in which body/self-esteem and stressful recent events are significant contributors.
