Familiarity and attraction to stimuli: Developmental change or methodological artifact?

One hundred thirteen 7-, 9-, and 11-year-old children viewed a series of stimuli consisting of Chinese characters exposed a different number of times. Following exposure to the stimuli, children ranked the stimuli according to liking. Seven- and 9-year-olds preferred the more familiar characters to those seen less frequently, but the oldest children preferred novel stimuli. In rankings taken 3 weeks after original exposure, a subsample of 11-year-olds preferred the more familiar characters. These results suggest that discrepancies obtained in previous research on the affective consequences of mere exposure are of methodological rather than developmental origin. Possible critical differences in procedure are discussed.     

Improvement of affect following exercise: methodological artifact or real finding?

The purpose of this study was to examine the "sense of relief" effect as a potential explanation for improvement of affect following exercise. The current study included male and female participants, four exercise/expectancy conditions, and assessed six dimensions of affective space. Participants were 134 undergraduates. Heart rate and affect were assessed four times: upon entering the lab, after disclosure of assigned experimental condition, immediately after exercise, and 15-min post exercise. An examination of differences between initial measures and measures taken after disclosure of condition revealed significant changes in feelings of anxiety, calmness, and tiredness, as well as heart rate. No gender differences were observed. The results support the existence of a "sense of relief" effect, but the effect is more pronounced for physiological arousal as opposed to affect.     

Increasing similarity in the values and life plans of male and female college students? Evidence and implications

A time-series analysis of college freshmen indicates that from 1969 to 1984 there has been a dramatic increase in the value women place on status-attainment goals, but not a comparable decrease in the value placed on domestic-nurturant goals—a pattern that reflects an amalgamation rather than a masculinization of the feminine value constellation. As the value placed on status-attainment goals has not increased as significantly for males, there has been a narrowing of the difference in the value constellations of the sexes over this time period. Further, there has been a greater increase in the percentage of women than men aspiring to graduate degrees and to the highest status professional and executive occupations, resulting in increased congruence in the educational and high-status career goals of women and men. The limitations and implications of these data are discussed.The research for this paper was funded by a grant from the Josiah Macy Jr. Foundation.

Goals of male and female college students: Do traditional sex differences still exist?

Importance ratings of reasons for attending college were obtained from male and female undergraduates. Responses were compared for sex differences and were compared to the responses of subjects in the Constantinople (1967) study. The picture of college students that emerged is very different from those of previous studies. Current females did not emphasize career goals less, nor social goals more, than males. Current males were more interested in social aspects of college than were their male predecessors. Male and female concepts of success seemed to differ. To females challenge and accomplishment were most important; to males, complying with parental pressures and economic success were most important.The authors thank Phillip Shaver for his helpful comments on an earlier version of this article.     

The Mehrabian measures of achieving tendency: are separate male and female scales necessary?

The 1969 male and female Mehrabian measures of achieving tendency are among the best-known measures of resultant achievement motivation. This study addressed the question of whether unique male and female items are necessary. Pearson product-moment correlation analyses on 83 male and 184 female undergraduates showed that females' scores on the unique male items correlated positively with their scores on the original female scale, and males' scores on the unique female items correlated positively with their scores on the original male scale. Coefficient alpha reliabilities of the original male and female forms were found to be acceptable. Cluster analyses showed that the Mehrabian items cluster in very similar ways for both males and females.     

Person orientation of male and female high school students: To the Educational disadvantage of males?

Potential differences in the person orientation of male and female high school students that are likely to have a significant influence on their achievement strivings were investigated. A questionnaire, consisting of several indices of person orientation, was administered to 848 grade 10 and 12 students. The data revealed that boys are especially susceptible to anti-intellectual influences from their peers and suggest that the interference of affiliative concerns with achievement behavior, a problem that has received considerable attention in the psychology of women, may also be very relevant to understanding the academic underachievement of males.     

Suicide and the contemporary woman: Are male and female suicide rates converging?

Nationwide statistics on White suicide rates for the years 1960–1978 are examined to assess whether the suicide rates of women are increasing relative to those of men. This is accomplished by calculating for the total population and for several age groupings the sex differential (SD), which is defined as the percentage of suicides which are female after adjustments are made for the sex distribution in the population. The data reveal that the SD narrowed from 1960–1967, held steady from 1968–1972, and then widened slightly from 1973–1978. The most important aspects of these trends are that (a) the narrowing of the SD is due more to declining suicide rates among older (over-40) males than to increasing female suicide rates, and (b) the narrowing of the SD and the small increases in female suicide rates occurred prior to 1970 and thus were earlier than would be expected on the basis of changing sex-role expectations. Post hoc explanations of these patterns refer to methodological factors and to changes in social integration resulting from a variety of sociohistorical factors.     

Spearman's law of diminishing returns: A statistical artifact?

Spearman's Law of Diminishing Returns (SLODR) is the idea that the structure of human cognitive ability is more differentiated and g a weaker determinant of cognitive performance at higher levels of ability. In this study, we distinguish between ‘traditional’ methods of testing SLODR and ‘contemporary’ methods of testing SLODR. It is the former set of methods from which the vast majority of the evidence base for SLODR derives. We demonstrated that it is easy to mimic SLODR and reverse SLODR effects in these traditional methods of assessing SLODR by using data with skewed observed variable distributions. The skewness magnitudes did not need to be large to produce these effects and they fell well within the range of values that are usually considered unproblematic for parametric statistic analysis. In simulated datasets, positive subtest skewness resulted in SLODR and negative subtest skewness resulted in reverse SLODR. In contemporary methods of testing SLODR, non-linear g-loadings or a skewed g are assumed to reflect evidence for SLODR. When we applied contemporary methods of testing SLODR to these data, there was evidence of heteroscedastic residuals but no evidence of non-linear g-loadings or skewed g distributions. We broadly replicated the effects of subtest skew from these simulated datasets in real data from the Minnesota Study of Twins Reared Apart. Results imply that traditional methods of assessing SLODR cannot distinguish between effects due to subtest characteristics that have nothing to do with differences in ability structure at different levels of g and true SLODR effects. This calls into question the empirical support for SLODR.     

Having it all? Combining work and family in a male and a female profession

Are women in a female-dominated profession more successfully able to combine work and family obligations than women in a male-dominated profession? To explore this question, a comparison was made between the family status and careers of 747 women librarians (a female-dominated profession) and those of 449 women MBAs (a male-dominated profession). It was expected that the librarians would marry earlier and have more children. This general prediction was not supported. Over half of both groups of women were married, and after controlling for age, there were no differences in number of children. However, many women without children in both groups reported that they would like to be mothers. This disparity between wanting children and not having them was more common for women MBAs than women MLSs. MBAs and librarians were about equally likely to have had job interruptions, but librarians were more likely to have worked part-time. Reasons for an interruption to full-time work were as likely to be for problems finding (full-time) work as for family responsibilities. Librarians' salaries were much lower, but job interruptions and part-time work had a more negative effect on the salaries of women in business. In sum, the data suggest that many of the women surveyed have not combined motherhood with a professional career and that it is probably somewhat more difficult to combine a family with a career in business than with a career in library science.     

Are sex-role attitudes useful in explaining male/female differences in rates of depression?

This study used an untreated sample of husbands and wives to investigate the effect of a wife's employment status on her spouse's depression score. A consistency between attitudes toward appropriate sex-role behavior and actual situation was expected to enhance mental well-being. Data demonstrate that when a measure of sex-role attitudes was paired with situation, it was a significant indicator of depression scores for unemployed females. Housewives with liberal views toward sex roles felt more restricted and were more depressed than were traditional housewives. Sex-role orientation was not effective in explaining depression scores for working wives or for husbands in the sample. The findings emphasize the necessity for examining the impact of sex-role orientation on depression both by sex and by situation.     

A methodological note on nonlinear time series analysis: is the open- and closed-loop model of Collins and De Luca (1993) a statistical artifact?

The authors reexamined, theoretically and empirically, the method proposed by J. J. Collins and C. D. De Luca (1993) for the analysis of center-of-pressure trajectories. The main argument in this article is that Collins and De Luca's approach is not adapted to the analysis of bounded time series and leads to statistical artifacts such as underestimation of the diffusion process for long-term intervals. The open- and closed-loop model developed by Collins and De Luca is a direct consequence of those statistical problems. Applying more classical methods, such as rescaled range analysis or detrended fluctuation analysis, the authors show that center-of-pressure trajectories can be modeled as continuous, antipersistent fractional Brownian motion. More specifically, those trajectories behave like 1/f noise, a ubiquitous feature in adaptive biological systems.     

Who is more violent in extremist groups? A comparison of leaders and followers

Few prior studies have examined the extent to which the behavior and characteristics of political extremists are related to their position within radical groups. In this paper we concentrate on one of the most fundamental distinctions in groups: That between leaders and followers. Our main goal is to investigate the comparative propensity of leaders and followers to engage in political violence. In a sample of individuals who have committed ideologically motivated political crimes in the United States (N = 1,331). we found that even though leaders were more ideologically committed to the group's goals and ideologies, they were at the same time less likely to engage in violent acts. Moreover, we found that leaders in radical criminal organizations shared many characteristics with leaders in noncriminal organizations. Specifically, in comparison to followers, they were more often male, older, and they were more likely to belong to an ethnic majority. We consider implications for future research and policy of the fundamental conclusion that compared to leaders, followers in terrorist organizations are more likely to engage in violent acts.     

Slang: A male domain?

A brief overview of various definitions of the problematic term “slang” precedes a discussion of stereotyped perceptions of slang and whether it is a male or female linguistic characteristic. Following this is a report on an investigation carried out on 160 South African adolescents, which attempted to measure the effect of the following variables on the use of slang: sex, age and type of school. Although interesting sex-related differences are revealed in the results, which can be correlated with the theme of social power and status, it is argued that the expected differences between males and females in this area are not as striking as one is led to believe by literature in the field, and that the gap is likely to close: it is probably not the sex of the speaker alone that influences slang usage, but also, and perhaps more importantly, his/her age and scholastic environment.     

Being female and athletic: A cause for conflict?

This study examined the interrelationships among role conflict, gender role orientation, and female sport participation. One hundred six female high school athletes and nonathletes were administered the Personal Attributes Questionnaire and a role conflict inventory. Multivariate analyses revealed that athletes experienced significantly higher levels of role conflict than nonathletes, but a nonsignificant relationship was found between role conflict and gender role orientation. Role conflict was also unrelated to type of sport, although team athletes high in feminine orientation perceived higher role conflict than low feminine oriented athletes. Overall, levels of perceived and experienced role conflict were low. In sum, role conflict does not appear a major concern for adolescent female athletes nor was gender role orientation a factor related to conflict between the roles of female and athlete.     

A study of the “central life interests” and “work attachments” of male and female workers

This paper reports the results of a survey undertaken to investigate the overall central life interests and attachments to work of a sample of 1112 male and female employees of six Southern California manufacturing firms. The major conclusions suggested by this study are three. First, male employees have a slight tendency to be more work oriented in their overall central life interests than female employees. Second, female employees tend to be more strongly attached to extrinsic work features than male employees. Third, male-female differences in occupational status and perceived mobility opportunities probably account for gender differences in overall central life interests but these variables do not account for the tendency for women to be more strongly attached than men to extrinsic work features.     

A study of male and female soldiers' beliefs about the “appropriateness” of various jobs for women in the army

The purpose of this paper is to document the often discussed (e.g., Goldman, 1973) and recently initiated expansion of women's role in the U.S. Army and to present evidence regarding one aspect of soldiers' probable reaction to this expansion — viz., the extent to which soldiers believe certain military jobs are appropriate for women and, in particular, the extent to which these beliefs are related to respondent sex, rank, and expectation of leaving the Army before retirement.     

Eve and Adam--is a partnership between the male and female actually possible?

Whereas the girl can pattern the formation of her post-oedipal gender-typical selfrepresentation on the model of her mother, the boy must give up the maternal object and turn to the father. The author believes that the reorientation consumes energy which the boy lacks when forming his ego structures, his frustration tolerance, his capacity for relationships. This deficit model is invoked to explain the commonly deplored typically male behavioral and attitudinal characteristics.     

Gender differences in mathematics anxiety: An artifact of response bias?

Abstract

Females are more likely than males to report anxiety about mathematics. Hunsley and Flessati (1988) examined two explanations for this difference: the sex-role socialization hypothesis, which states that gender differences occur as a result of differences in socialization, and the math experiences hypothesis, which states that math anxiety is due to previous experiences with mathematics, regardless of gender. They found support only for the math experiences hypothesis, and suggested that the gender difference in math anxiety may be an artifact of response bias.

The present study replicated the Hunsley and Flessati study and included an evaluation of response bias. One hundred and fifty Introductory Psychology students completed a series of questionnaires examining mathematics anxiety, attitudes and mathematical background. The findings of Hunsley and Flessati were replicated, however no evidence was found for a gender-linked response bias. An alternative explanation for the gender difference in math anxiety is proposed based on the finding that females are more self-critical.
