Social class and sex as determinants of future orientation (time perspective) in adults

This studv was designed to test hypotheses concerning the influence of sex roles and social status on future orientation (FO). The latter was measured in various categories (spheres of life),on the dimensions of density (number of hopes andfears cited by the subject), extension, and optimism-pessimism. Also included was a measure of ‘internal vs. external control’ (the subject's assessment as to whether the realization of his hopes and fears is dependent more on himself or more on external factors). Subjects were 100 employed men and women of the lower and middle class. It was found that, in comparison with women, men voiced more hopes/fears in the public sphere (economy, politics, environment) and fewer in the private sphere uamily, occupation, personal development). Men had a more extended FO in the occupational and economic spheres; women, in contrast, in the private sphere. (These results contradicted the assumption of earlier studies that FO is a general orientation, not varying across different domains of life.) Middle-class (in comparison to lowerclass) persons manifested a, wore extended FO, envisioned the distant future more optimistically, and believed more markedly that the realization of their hopes and fears depended on themselves.     

Self-esteem,locus of control,and task difficulty as determinants of task performance

One hundred twenty-six high school students responded to questionnaire measures of chronic self-esteem (CSE), task-specific self-esteem (TSSE), and locus of control of reinforcements (L of C) and were given a list of anagrams to solve that varied in level of task difficulty (TD). L of C and (to a lesser extent) TSSE were each related to task performance (TP), multiple R = .51 (p < .01). CSE was not related to TP. The overall relationships of TSSE and L of C with TP were each moderated significantly by TD. The results are discussed in terms of a gradual specification of the “boundary conditions” within which cognitive consistency theory and social learning theory may be applicable.     

Social class and family size as determinants of attributed machismo,femininity, and family planning: A field study in two South American Communities

The major objective of the present investigation was to ascertain how stereotypes of machismo and femininity are related to acquired family size and perceptions of family planning. An indirect measurement approach was employed in which lower-class and upper-middle-class urban adults in Cali, Colombia, responded to photos of Colombian families which varied in size and completeness. The principal findings of the investigation revealed that (1) lower-class subjects described parents in the photos as significantly more macho and feminine because of their children than upper-middle-class subjects; (2) although no overall family size effect on attributions of machismo and femininity to parents emerged, lower-class female subjects described parents of large complete families as significantly more macho and feminine than parents of small complete families; (3) male subjects from both social classes described male spouses in the photos as more dominant and in greater control of the marital relationship as family size in the photos increased; and (4) perceptions of the incidence of family planning behaviors decreased linearly with family size for both social classes, although lower-class females attributed more family planning to spouses of large families than upper-middle-class females. Discussion of these results attempted to account for social class differences in the significance of parenthood as an indicator of sex-role identity and the psychological relevance of male dominance as a factor in fertility.This research was supported by a predoctoral research fellowship from the Council of Intersocietal Studies, Northwestern University, Evanston, Illinois 60201.     

Chinese adolescents' perceptions of family functioning: personal,school-related,and family correlates

The author used two translated measures (Self-Report Family Inventory; D. T. L. Shek, 1998); and Family Assessment Device; N. B. Epstein, L. M. Baldwin, & D. S. Bishop, 1983) and a locally developed scale (Chinese Family Assessment Instrument; D. T. L. Shek, in press-a) to assess 3,649 Chinese adolescents' perceptions of how well their families function. He found that boys perceived their families to function worse than did girls and that younger adolescents perceived their families to function better than did older adolescents. Perceived family functioning was negatively related to grade level; students attending schools with higher academic standards perceived their families to function better than did students attending schools with lower academic standards; and students attending government and aided schools had higher levels of family functioning than did students attending private schools. Family types (intact vs. nonintact families) and the duration of parents' stay in Hong Kong were also related to the adolescents' perceptions of family functioning. Findings for the personal, school-related, and family correlates of perceived family functioning were statistically significant and stable across different measures of family functioning, but the practical significance of the findings was not high.     

Caffeine as a performance-enhancing drug in rats: sex, dose, housing, and task considerations

Past animal studies of the performance-enhancing properties of stimulant drugs, such as caffeine, may have suffered from a number of procedural and ethical problems. For example. the housing condition of the animals was often not taken into consideration. As well, endurance tests, such as the forced swim task, sometimes involved ethically (and procedurally) questionable interference with natural swimming behaviour. Some of the manipulations, such as attaching a weight to the swimming animal's tail to increase the difficulty of the task and using mortality as a dependent variable, seem grotesque, even unnecessary. In this experiment, the performance-enhancing effects of caffeine in a modified forced swim task and a dominance task were evaluated using male and female rats as subjects (N=60), housed in either enriched or isolated environments. Analysis indicated that rats respond to caffeine as an interactive function of sex, housing, dose, and task characteristics. It was concluded that performance-enhancing properties of stimulant drugs may be the result of a complex interplay of variables, making simple generalizations questionable.     

Macrosocial determinants of social integration: Social class and area effect

Theory and research on social support have paid little attention to the existence of important macrosocial variables determining level and content of social relationships. This study examines variations in social integration as a function of social class and residential area characteristics. Results for 234 subjects living in high and low risk neighbourhoods indicated that differences between higher and lower social class groups follow different patterns in different residential areas. Also, same social class position appeared to have different significance as a function of residential area characteristics. The levels of three social integration measures—community integration and satisfaction, community association and participation, and contribution in community organizations—were significantly higher for lower class in low risk neighbourhoods than in high risk ones. However, significant differences were found in only one measure for higher social class groups, with higher levels of community association and participation in high risk neighbourhoods than in low risk ones. The discussion examines a ‘social impoverishment’ hypothesis for high risk environments, and proposes possible protective factors for higher status residents. Relations between formal and informal sources of support, and implications for social intervention strategies are also considered.     

Emergent leadership as a function of sex and task type

Emergent leadership was examined in relation to sex and task type; 120 subjects participated in four-person mixed-sex groups. Three task conditions (masculine, neutral, and feminine gender orientations) were tested with 10 groups in each condition. It was predicted and found that more men than women would emerge as leaders in the masculine and neutral task conditions, while more women would assume the leadership role in the feminine task condition. The effects of the gender orientation of a task are discussed. It is suggested that expertise with a task may explain the task type effect found.This study is based on the senior author's master's thesis, conducted at Wayne State University under the direction of the second author.     

Social interpretation bias and generalized social phobia: the influence of developmental experiences

Patients with generalized social phobia (N = 42) and non-phobic community controls (N = 42) engaged in a social interaction with an experimental assistant whose behavior was used to create either a positive or an ambiguous social environment. Participants then rated their own performance and their partner's behavior. As a group, social phobic patients displayed negatively biased self-judgments, but failed to display biased social interpretations. Among the social phobia group, a social developmental history marked by parental hostility was associated with negative interpretations of partner behavior and a history of parental overprotection was associated with less sensitivity to partner behavior. The results supported cognitive models of social phobia, which implicate negative learning experiences in the development of information processing biases.     

Age differences in reaction time and attention in a national telephone sample of adults: education, sex, and task complexity matter

This study demonstrated effects of age, education, and sex on complex reaction time in a large national sample (N = 3,616) with a wide range in age (32-85) and education. Participants completed speeded auditory tasks (from the MIDUS [Midlife in the U.S.] Stop and Go Switch Task) by telephone. Complexity ranged from a simple repeated task to an alternating task that involved central executive processes including attention switching and inhibitory control. Increased complexity was associated with slower responses in older adults, those with lower education, and women, even after controlling for differences in health status. Higher levels of education were associated with greater central executive efficiency across adulthood: Overall, adults with college degrees performed on complex tasks like less educated individuals who were 10 years younger, up to age 75. These findings suggest that advanced education can moderate age differences on complex speeded tasks that require central executive processes, at least up to the point in old age at which biological declines predominate. The approach demonstrates the utility of combining laboratory paradigms with survey methods to enable the study of larger, more diverse and representative samples across the lifespan.     

Brain size and cognitive ability: Correlations with age,sex, social class,and race

Using data from magnetic resonance imaging (MRI), autopsy, endocranial measurements, and other techniques, we show that (1) brain size is correlated with cognitive ability about .44 using MRI; (2) brain size varies by age, sex, social class, and race; and (3) cognitive ability varies by age, sex, social class, and race. Brain size and cognitive ability show a curvilinear relation with age, increasing to young adulthood and then decreasing; increasing from women to men; increasing with socioeconomic status; and increasing from Africans to Europeans to Asians. Although only further research can determine if such correlations represent cause and effect, it is clear that the direction of the brain-size/cognitive-ability relationships described by Paul Broca (1824–1880), Francis Galton (1822–1911), and other nineteenth-century visionaries is true, and that the null hypothesis of no relation, strongly advocated over the last half century, is false.     

Perceived rationality,morality, and power of social choice as a function of interdependence structure and social value orientation

The present study examines how individuals with different social value orientations (i.e. prosocial, individualistic, and competitive) construe the rationality, morality, and power of choices in four distinct interdependence structures which systematically differ in the motives that could underlie the most prosocial or least aggressive choice: (a) altruism only, (b) altruism and cooperation, (c) altruism, cooperation, and individualism, and (d) altruism, cooperation, individualism, and competition. Results revealed that rationality ratings, and to a lesser degree morality and power ratings, increased most when the motives that could underlie a choice were part of the perceiver's social value orientation. Overall, the pattern of rationality ratings provided reasonable support for the Goal Prescribes Rationality Principle. Ratings of morality and power suggested a corresponding Goal Prescribes Morality/Power Principle (for prosocials and individualists), but revealed only mixed support for the Might Over Morality Hypothesis.
