Is Virginia for lovers? Geographic variation in adult attachment orientation

People often use relationships to characterize and describe places. Yet, little research examines whether people’s relationships and relational style vary across geography. The current study examined geographic variation in adult attachment orientation in a sample of 127,070 adults from the 50 United States. The states that were highest in attachment anxiety tended to be in the mid-Atlantic and Northeast region of the United States. The states that were highest in attachment avoidance tended to be in the frontier region of the United States. State-level avoidance was related to state-level indicators of relationship status, social networks, and volunteering behavior. The findings are discussed in the context of the mechanisms that may give rise to regional variation in relational behavior.     

Sex differences in regret: all for love or some for lust?

Few sex differences in regret or counterfactual thinking are evident in past research. The authors discovered a sex difference in regret that is both domain-specific (i.e., unique to romantic relationships) and interpretable within a convergence of theories of evolution and regulatory focus. Three studies showed that within romantic relationships, men emphasize regrets of inaction over action (which correspond to promotion vs. prevention goals, respectively), whereas women report regrets of inaction and action with equivalent frequency. Sex differences were not evident in other interpersonal regrets (friendship, parental, sibling interactions) and were not moderated by relationship status. Although the sex difference was evident in regrets centering on both sexual and nonsexual relationship aspects, it was substantially larger for sexual regrets. These findings underscore the utility of applying an evolutionary perspective to better understand goal-regulating, cognitive processes.     

Sex differences in competition—cooperation behavior of children at two age levels

Competitive or cooperative behaviors of children were observed in two experiments. In Experiment 1, 7- to 9-year-old boys and girls played a board game with same- or opposite-sex partners under instructions which stressed either group or individual performance. Girls' behavior varied as a function of both instructions and partner sex. Girls playing the game with boys showed more highly competitive behavior than did girls who played the game with girls. Boys were highly competitive under all conditions. In Experiment 2, preschool children were observed in a similar game. For both sexes, children who played the game with opposite-sex partners were more competitive and obtained fewer rewards than those who interacted with same-sex partners. Thus, with development, boys show a change from selective competitiveness to a very general tendency to compete, while girls show a consistent tendency to vary their game behavior according to situational cues such as those provided by instructions or the sex of a game partner.A report of the first experiment was made at the Third Biennial Southeastern Conference of the Society for Research in Child Development, Chapel Hill, March 1974. The authors would like to thank the personnel of St. Francis Cabrini School and the Children's House Montessori School of New Orleans, Louisiana, for their cooperation in providing research participants.

Sex differences in aggression: Are current notions misleading?

Studied experimentally the influence of norms and sex of subjects on aggressive behaviour in same sex dyads. Two hypotheses were tested: (1) subjects will react aggressively to an unpleasant state of affairs, if they interpret it as being the result of violation of a norm on the part of another; (2) female subjects will display more aggression than male subjects under conditions of repeated provocation while male subjects will be more aggressive under conditions of infrequent or no provocation. In a 2 × 2 × 2 complete factorial design (norm violation versus norm enforcement; male versus female; low versus high reward for performance) 20 same sex pairs of students performed alternatively a sensory-motor task (victim) and a shock delivery task (aggressor). As predicted, subjects who consider other's behaviour to be a norm violation aggress more often (p <.0001). A significant interaction between sex of subject and norm violation is found in support for the second hypothesis (p <.05). It is concluded that positions grounded on the S-R paradigm are misleading for the understanding of sex differences in aggression.     

Sex differences in conformity: Instrumental or communal response?

Male and female introductory psychology students (N=88) were asked to read a clinical case history and the opinion consensus of either (a) their peers, (b) advanced psychology students, or (c) Ph.D. clinical psychologists that the patient should be hospitalized for at least 90 days (an extreme treatment). Subjects then indicated on a scale of 10 to 90 days, the length of hospitalization they thought best. In a significant interaction effect (sex of subject × expertise of source) males were least influenced by the opinions of their peers and increasingly influenced as the source became more expert. Females, however, seemed most influenced by their peer group, recommending longest hospitalization terms in that condition. Results are interpreted in terms of sex-role identification and the emergence of an instrumental (task) or communal set.     

Sex differences in college student-teacher interactions: Fact or fantasy?

On-site observations analyzing student-teacher interaction for 50 college classes, matched by level, subject, and teacher's sex, revealed no difference in number and type of interactions in which male and female students participated. In female-taught classes, style differences were found: Male students' interactions were characterized by more student-teacher exchanges than females' interactions. From student questionnaires, differences in office visitation patterns were revealed, showing an apparent relationship to sex: Female students visited more female than male instructors. However, closer examination showed the student's major to be the key variable influencing visitation patterns. Results point to the need for testing a variety of variables in addition to sex before drawing conclusions about sex-related behavior.Ordering of authors was determined alphabetically.

Did you have sex with him? Do you love her? An in vivo test of sex differences in jealous interrogations

Abundant evidence suggests that between sex differences exist in the degree to which cues to sexual and emotional infidelity trigger jealousy. A criticism of this research is that this commonly found sex difference is a consequence of the hypothetical scenario and forced-choice methodology that is commonly employed. This study used a novel method to explore the nature of jealousy-fueled interrogations (N = 75) in the face of actual infidelities captured on video in the syndicated reality program Cheaters. Fifty-one episodes of Cheaters were content analyzed by six coders trained to watch each episode. As predicted, men were more likely than women to inquire about the sexual aspect of their partners’ infidelities, whereas women were more likely than men to inquire about the emotional aspect of their partners’ infidelities. These results suggest that humans have sex-differentiated damage assessment strategies dedicated to investigating the nature of their mates’ extra-pair relationships. Although previous studies have found sex differences in jealousy using prospective and retrospective reports, this is the first study to demonstrate sex differences in romantic jealousy in vivo. These findings refute the criticism that sex differences in jealousy are mere methodological artifacts. Discussion focuses on the benefits and limitations of content-analyzing Cheaters.     

Distributional reaction time properties in the Eriksen task: marked differences or hidden similarities with the Simon task?

In conflict tasks, the irrelevant stimulus attribute needs to be suppressed for the correct response to be produced. In the Simon task, earlier researchers have proposed that this suppression is the reason that, after an initial increase, the interference effect decreases for longer RTs, as reflected by late, negative-going delta plots. This view has been challenged by observations of positive-going delta plots, even for long RTs, in other conflict tasks, despite a similar necessity for suppression. For late negative-going delta plots to be interpreted as reflecting suppression, a necessary, although maybe not sufficient, condition is that similar patterns should be observed for other conflict tasks. We reasoned that a similar suppression could be present, but hidden, in the Eriksen flanker task. By recording and analyzing electromyograms of the muscles involved in response execution, we could compute delta plots separately for trials that elicited a subthreshold incorrect response activation (partial error). Late negative-going delta plots were observable on partial-error trials, although they were weaker than for the Simon task, reducing the impact of this inversion on the overall distribution. We further showed that this pattern is modulated by time pressure. Those results indicate that mechanisms leading to negative-going delta plots, similar to those observed in the Simon task, are also at play in the Eriksen task. The link between negative-going delta plots and executive online control is discussed.     

Sex differences in jealousy: evolutionary mechanism or artifact of measurement?

Two studies are presented that challenge the evidentiary basis for the existence of evolved sex differences in jealousy. In opposition to the evolutionary view, Study I demonstrated that a sex difference in jealousy resulting from sexual versus emotional infidelity is observed only when judgments are recorded using a forced-choice response format. On all other measures, no sex differences were found; both men and women reported greater jealousy in response to sexual infidelity. A second study revealed that the sex difference on the forced-choice measure disappeared under conditions of cognitive constraint. These findings suggest that the sex difference used to support the evolutionary view of jealousy (e.g., D. M. Buss, R. Larsen, D. Westen, & J. Semmelroth, 1992; D. M. Buss et al., 1999) likely represents a measurement artifact resulting from a format-induced effortful decision strategy and not an automatic, sex-specific response shaped by evolution.     

Sex differences in attraction to infants: When do they occur?

Harlow (1971) observed that all-female college audiences responded to a pictured infant rhesus monkey with an “ecstasy response,” while males were “completely unresponsive,” and females in coeducational audiences “inhibited the ecstasy response,” explaining these differences in terms of innate sex differences. The present study compared college students' self-reported attraction to pictures of 15 infant and adult nonhuman primates under several conditions. Infant pictures were of two types: infants which were engaged in typical infant behaviors (Infant Behavior), and those which were not (Infant). Subjects made judgments in same- or mixed-sex groups and reported degree of attraction publicly or privately. Ratio scores were used to represent each subject's attraction to infant or infant-behavior pictures compared with his or her attraction to pictures of adults. There were no significant sex differences in attraction to infant or infant-behavior pictures, and sex did not interact with any other variable. However, situational variables significantly affected the response. Males as well as females reported greater attraction to infant and infant-behavior pictures when they viewed the pictures in same-sex compared with mixed-sex groups. Both sexes reported greater attraction to infant and infant-behavior pictures privately than publicly.     

Sex differences in motor performance of young children: Fact or fiction?

Prepubescent boys and girls who had participated for one or more years in a coeducational physical education program were classified by grade (3, 4, and 5) and year (1977, 1978, and 1979). Scores from the AAHPER Youth Fitness Test were analyzed for differences. Results indicated that females at prepubescent ages may be expected to perform at similar levels to boys of the same age on most test items. While differences were not significant, girls in 1979 were actually better than boys of the same age from the two previous years.     

Is middle childhood attachment related to social functioning in young adulthood?

The aim of the present study (N = 69) was to examine whether middle childhood attachment, measured using the Separation Anxiety Test (Slough, Goyette & Greenberg, 1988), predicts aspects of social functioning (social initiative, prosocial orientation, social anxiety, loneliness) in young adulthood. Insecurity‐avoidance at age 8.5 years was, as expected, negatively related to social initiative and prosocial orientation, and was also positively related to social anxiety and loneliness at age 21 years. In addition, insecurity‐avoidance contributed to developmental change in social anxiety from middle childhood to young adulthood. Contrary to our expectations, the two security scales were generally unrelated to future social functioning. Taken together, these results extend previous research by showing that insecurity‐avoidance is related to social functioning also beyond childhood and adolescence, and that it contributes to developmental change in social functioning over time. The scarcity of prospective links for the attachment security scales points to the need for future studies addressing when and why attachment does not contribute to future social functioning.     

Is beauty talent? Sex interaction in the attractiveness halo effect

Two experiments were performed to replicate and extend previous findings of judgmental bias which favors physically attractive people. In the first experiment male and female subjects judged an essay purportedly written by an attractive or an unattractive female author. The attractive author was rated as significantly more talented by male judges. Female judges rated the attractive author as less talented, although this difference was not statistically significant. A second experiment concerned ratings by males and females of essays written by attractive or unattractive male authors. The results suggested that the attractiveness halo effect does not occur for male authors.A similar version of this article was presented at the meeting of the Western Psychological Association, Los Angeles, April 1976.

Sex differences in graduate student ambition: Do men publish while women perish?

This paper compares men and women graduate students at one university and identifies conditions under which women students equal or surpass men in ambition. Men and women were broadly similar in background characteristics, though different in current family status. They studied different subjects, aimed for different degrees, and were concentrated in different years in the university. If women were to equal the most highly ambitious men on ambition to publish and engage in related behaviors, they had to aspire to a doctorate, survive past the second year of study, and have nontraditional attitudes toward women's role. The results are discussed in terms of differential student careers and barriers to the development of ambition in student women.The research upon which this paper is based was carried out with the assistance of a Lena Lake Forrest Fellowship from the Business and Professional Women's Foundation, Washington, D.C.The author wishes to thank G. L. Millerson and C. T. Husbands for comments on the draft, and Beryl Collins and Bryn Saunders for help with the typing.     

Sex differences in intrinsic aptitude for mathematics and science?: a critical review

This article considers 3 claims that cognitive sex differences account for the differential representation of men and women in high-level careers in mathematics and science: (a) males are more focused on objects from the beginning of life and therefore are predisposed to better learning about mechanical systems; (b) males have a profile of spatial and numerical abilities producing greater aptitude for mathematics; and (c) males are more variable in their cognitive abilities and therefore predominate at the upper reaches of mathematical talent. Research on cognitive development in human infants, preschool children, and students at all levels fails to support these claims. Instead, it provides evidence that mathematical and scientific reasoning develop from a set of biologically based cognitive capacities that males and females share. These capacities lead men and women to develop equal talent for mathematics and science.     

Sex differences in social representations of aggression: Men justify,women excuse?

Women tend to hold an expressive social representation of aggression (as a loss of self‐control) while men tend to hold an instrumental representation (as a means of imposing control over others). Because expressive beliefs correspond to excuses and instrumental beliefs to justifications, it may be a sex difference in moral acceptability of aggression that informs social representation. Participants completed the Expagg questionnaire with reference to an episode of same‐sex or cross‐sex physical aggression and rated the moral acceptability of their behaviour. Women scored higher on Expagg (specifically lower than men on the instrumental scale) but there was no effect of target sex or participant‐by‐target interaction. Contrary to expectation, women rated their own aggression as more acceptable than did men and hence this could not explain their lower levels of instrumentality relative to men. Aggr.
