Are sex differences in nonverbal and verbal behavior generalizable to mentally retarded persons?

Sex differences in three communication behaviors consistently found to be more common among females than males — smiling, gazing at one's partner, and sentence complexity — were examined through analysis of interviews with 78 institutionalized mentally retarded adults. While females were significantly more likely than males to smile or laugh, and tended to use longer, more complex sentences, the commonly observed sex difference in gazing failed to generalize to a retarded sample. These findings clarify limits on the generalizability of sex differences beyond college students and other normal populations.This research was partially supported by a grant to the Texas Tech University Research and Training Center in Mental Retardation from the Rehabilitation Services Administration, Department of Health Education, and Welfare.     

Touching Behavior in Sport: Functional Components, Analysis of Sex Differences, and Ethological Considerations

Little research exists regarding sex differences in touching behavior in sport or recreational settings. This study investigates sex differences in amounts, types, and factors influencing same-sex touching in a sport context. Subjects were 119 members of four men's college varsity baseball teams and 52 members of three women's college varsity softball teams. All touches performed on-field between team members were recorded and classified using an ethogram designed for this study. As hypothesized, statistically significant differences were found in the following areas: females performed more touching behaviors than males, almost half of the behavior types observed were performed more frequently by one sex than the other, males performed touching behaviors more frequently at away than home games, females performed touching behaviors more frequently at home than away games, and females performed more touching behaviors than males after negative game events. The findings and implications are discussed in relation to the touching behavior literature, ethology, and comparative psychology.     

Sex Differences in Self-awareness of Smiling During a Mock Job Interview

The present study examined sex differences in awareness of smiling behavior during a job interview, along with intended outcomes of false smiling. Male and female participants were assigned to the interviewee role of a mock job interview and were videotaped. Results indicate that women were more self-aware of false, but not genuine, smiling. In addition, women reported using false smiles to mask negative emotion and to appear enthusiastic more than did men. Naïve judges rated women who smiled in an attempt to mask negative emotion more harshly than men who smiled for this reason. Implications of these findings for the understanding of sex differences in smiling are discussed.     

Facial appearance,gender, and credibility in television commercials

The facial appearance of television spokespersons and the trustworthiness and expertise of the appeals delivered by them were independently rated. Babyfaced persons and females delivered communications which were less expert, but more trustworthy, than those communications delivered by maturefaced persons and males. These effects were independent of the spokespersons' perceived age, attractiveness, and amount of smiling. The findings are consistent with past research which has demonstrated that babyfaced people are perceived as less knowledgeable, but more honest, than those who are maturefaced.The authors are grateful to Mike Berbaum, Diane Berry, and two anonymous reviewers for helpful comments on an earlier draft. Portions of this research were presented at the 59th Annual Meeting of the Eastern Psychological Association in April, 1988, in Buffalo, N.Y.     

Testosterone, Smiling, and Facial Appearance

In a study of possible links between testosterone and dominance, 119 men and 114 women provided saliva samples for testosterone assay and posed smiling and not smiling for portrait photographs. Expert judges viewing the photographs found smaller smiles among high than low testosterone men, with less zygomatic major (raising the corners of the mouth) and orbicularis oculi (raising the cheeks and crinkling around the corners of the eyes) muscle activity. Naive judges viewing individual photographs gave higher potency ratings to smiling high testosterone men than smiling low testosterone men. Naive judges viewing photographs grouped into high and low testosterone sets gave higher potency and lower goodness ratings to high than to low testosterone men, regardless of whether they were smiling. Among women, judges found only slight relationships between testosterone and facial appearance. The pattern among men of less smiling with higher testosterone levels fits with research linking testosterone to face-to-face dominance.     

Increased Focus on the Mouth Among Infants in the First Year of Life: A Longitudinal Eye‐Tracking Study

This study examines face‐scanning behaviors of infants at 6, 9, and 12 months as they watched videos of a woman describing an object in front of her. The videos were created to vary information in the mouth (speaking vs. smiling) and the eyes (gazing into the camera vs. cueing the infant with head turn or gaze direction to an object being described). Infants tended to divide their attention between the eyes and the mouth, looking less at the eyes with age and more at the mouth than the eyes at 9 and 12 months. Attention to the mouth was greater on speaking trials than on smiling trials at all three ages, and this difference increased between 6 and 9 months. Despite consistent results within subjects, there was considerable variation between subjects. This raises the question of whether a developmental “norm” of face scanning in infancy ought to be pursued. Rather, these data add to emerging evidence suggesting that individual differences in face scanning might reliably predict aspects of later development.     

Assigned and Felt Status in Relation to Observer-Coded and Participant-Reported Smiling

Three experiments examined the relation of smiling to experimentally assigned interpersonal status and, within status groups, to self-reported feelings of status/power. In two of the experiments, participants' reports of own and partner smiling were also gathered and examined in relation to assigned status. In Studies 1 and 2, assigned status had no impact on smiling. In Study 3, lower-status participants smiled more than their higher-status partners in one experimental task; in the other task, lower-status participants smiled more than their higher-status partners only when the higher-status person was instructed to be controlling. In none of the experiments was self-reported status/power significantly related to actual smiling. Participant-reported smiling revealed a status effect that was much stronger than that found for actual smiling. Women smiled more than men, and this effect could not be accounted for in terms of status roles nor self-reported feelings of status/power.     

Behavior of Mothers and Infants With and Without Down Syndrome During the Still‐Face Procedure

There has been limited study of how the constitutional characteristics of infants with Down syndrome (DS) influence the patterning of their relations with caregivers. To assess natural and perturbed interactions between infants with DS and their mothers, we tested ten 6‐month‐old infants with DS and 20 typically developing (TD) 4‐month‐old of similar mental age. Participants were videotaped with their mothers in a natural face‐to‐face interaction, a brief period when the mothers adopted a still‐face, and a subsequent reengagement phase. There was little to distinguish the infants in the initial phase of natural interaction, but the mothers of infants with DS were more likely to show assertive warmth, and unlike in the case of mothers of TD infants, high maternal directiveness tended to be associated with lower levels of infant looking and lack of fussing. During the still‐face episode, infants of both groups showed reduced looking and smiling, although infants with DS tended to show lower levels of fussing and fewer in this group showed fussing in the reengagement phase. Therefore DS infants were somewhat similar to TD infants of comparable mental age in being responsive to the still‐face procedure, but showed indications of group differences in intense emotional reactivity.     

Race,Sex, and Perception of the Occupational Opportunity Structure among College Students*

Questionnaires were administered to 70 black female, 75 black male, 1,457 white female and 1,429 white male university freshmen. In order to test three alternative theories regarding perceptions of discrimination, analyses of variance related sex, race, and SES to total scores of perceived occupational discrimination against blacks (BDST) and against women (WDST). Blacks perceived significantly more discrimination against black people than did whites; neither sex nor SES differentialed scores on BDST. Black females and white males perceived significantly more discrimination against women than did white females; black females had the highest and white females the lowest WDST scores. A discriminant analysis on white females indicated that high WDST scorers were characterized by an “underdog syndrome” whereas low WDST scorers held internal, individualistic values. The findings indicated the greatest support for the formulation that differential anticipatory socialization into the role of “a person who is discriminated against” characterized white females who perceived more or less discrimination against women.     

Deterrence in the workplace: perceived certainty, perceived severity, and employee theft

The phenomenon of employee theft is examined empirically, utilizing a deterrence paradigm. Employees selected randomly from three different industry sectors and metropolitan areas were asked to self-report their involvement in a number of property theft activities within the employment setting. Using a weighted least-squares logit regression analysis, the study found that the perception of both the certainty and severity of organizational sanctions were related to employee theft. Males reported more theft than did females, but contrary to previous research, no gender/certainty or gender/severity interactions were observed. The best-fit model did, however, contain two significant first-order interactions: age/certainty and age/severity. These interactions strongly suggest that younger employees are not as deterrable as their older peers, especially under conditions of both high certainty and high severity of punishment. While a number of possible explanations might account for differential deterrability according to age, a commitment to or stakes in conformity explanation is proposed.     

Female sex offenders: a comparison of solo offenders and co-offenders

Even though much of the prior sex offender literature focuses on males, recent research has included females as offenders. Such research, however, has been limited by small sample sizes. Several researchers have proposed typologies of female sex offenders that include both females who act alone (i.e., solo offenders) and females who act with another person (i.e., co-offenders), often a male. The current research includes a cross-national sample of 123 females who were solo offenders and 104 who were co-offenders. It was found that the two groups of females were not significantly different in regard to their age, race, time of offense, and the location of the offense. Co-offenders were more likely than solo offenders to have more than one victim, to have both male and female victims, to be related to the victim, and to have a nonsexual offense in addition to the sexual offense listed.     

Differences in the Marriage Role Expectations of College Students from Intact and Divorced Families

The differences in marriage role expectations between college students of divorced and intact families were investigated using the Marriage Role Expectation Inventory (MREI). The MREI (Dunn and DeBonis, 1979) measures desires for traditional versus companionship style of marital relationships. It was hypothesized that those participants from divorced families would expect a more companionship oriented marriage role while those from intact families would expect a more traditional marriage role. Participants included 100 male and female students enrolled in introductory courses at Loyola University in New Orleans. Significant gender by marital status interactions were found in total MREI scores, as well as all eight MREI subscores. Males with married parents were more companionship oriented than males with divorced parents. On the other hand, females with divorced parents were more companionship oriented, while females with married parents were more traditional oriented in their marriage role expectations.     

Maternal Depressive Symptoms and 6‐Month‐Old Infants' Sensitivity to Facial Expressions

We examined 6‐month‐old infants' abilities to discriminate smiling and frowning from neutral stimuli. In addition, we assessed the relationship between infants' preferences for varying intensities of smiling and frowning facial expressions and their mothers' history of depressive symptoms. Forty‐six infants were presented pairs of facial expressions, and their preferential looking time was recorded. They also participated in a 3‐min interaction with their mothers for which duration of both mother and infant gazing and smiling were coded. Analyses revealed that the infants reliably discriminated between varying intensities of smiling and frowning facial expressions and a paired neutral expression. In addition, infants' preferences for smiling and frowning expressions were related to self‐reports of maternal depressive symptoms experienced since the birth of the infant. Potential implications for social cognitive development are discussed.     

Sensitivity to Social Contingency From Mothers and Strangers in 2‐, 4‐, and 6‐Month‐Old Infants

Infants' sensitivity to changes in social contingency was investigated by presenting 2‐, 4‐, and 6‐month‐old infants with 3 episodes of social interaction from mothers and strangers: 2 contingent interactions and 1 noncontingent replay. Three orders were presented: (a) contingent, noncontingent, contingent; (b) contingent, contingent, noncontingent; and (c) noncontingent, contingent, contingent. Contingency and carryover effects were shown to both mothers and strangers in the different orders of presentation. Infants were more visually attentive to contingent interactions than to the noncontingent replay when contingent interactions occurred prior to the replay, and the infants' level of attention to the noncontingent replay carried over to subsequent contingent interactions. The 4‐ and 6‐month‐old infants showed contingency and carryover effects by their visual attention and smiling. Examination of effect sizes for attention suggests 2‐month‐old infants may be beginning to show the effects. Reasons for age changes in sensitivity to social contingency are discussed.     

AGE-OF-RECALL EFFECTS ON FAMILY-OF-ORIGIN RATINGS

Family rating scales, particularly those tapping one's view of family of origin, rely heavily on one's summary impressions, perceptions, and recall of the family. Previous research has demonstrated that fairly consistent age, gender, and parent/offspring differences exist in ratings of current family functioning, but little information exists on such differences in rating one's family of origin. The present study had college-age subjects rate current family, family when they were elementary-school age, and family when they were 16 years old. Subjects were 141 college students (93 women, 48 men) who completed the self-Report Family Inventory (SFI) of the Beavers Systems Model of Family Functioning separately for the three specified recall periods (age 10, age 16, and current family). Significant differences were found between age-of-recall groups, with recall ratings from age 10 significantly more competent, cohesive, and less conflicted than those from age 16; current family ratings were intermediate. Relatively few gender by age interactions were significant. Implications for the use and interpretation of family ratings and family-of-origin scales are discussed.     

Gender-based expectancies and observer judgments of smiling

Beliefs about gender differences in smiling were measured by asking college students to rate how much they believed hypothetical women and men smile. Women were believed to smile more than men. Individual differences in this belief did not affect subsequent scoring of smiles, whether scored by counting the number of smiles exhibited by videotaped male and female targets or by rating the amount of smiling exhibited. An expectation about gender differences in smiling was experimentally induced, either that women smile more than men or that there is no gender difference in smiling. This expectation did not affect subsequent scoring of smiles, regardless of scoring method and regardless of whether the expectation was induced as a casual aside or in more formal instructions. In all conditions female targets were observed to smile more than male targets. Rating produced larger target gender effects than counting, but this could have been due to the nature of the rating process rather than observer bias.The authors gratefully acknowledge the assistance of Thomas Leahy and Joe Pieri in data collection, and of Cliff Brown and an anonymous reviewer for their comments on an earlier version of this paper.

The time it takes to identify facial expressions: Effects of age,gender of subject,sex of sender,and type of expression

Subjects were presented with 35 mm slides of faces and required to indicate the type of expression (pleasant or unpleasant) by a switch movement. Latency and accuracy were recorded. The variables of the study were age (early or late adolescence), gender of subject, sex of sender, and type of expression. The most important results were as follows: There was no age effect when the latencies were adjusted by a covariate to take account of age-related differences in general perceptual-motor skills. There was a strong interaction in which the female pleasant slides produced substantially lower latencies than the other three combinations of sex of sender and type of expression. A weaker interaction indicated faster identification for the female sender, female subject condition than the other three combinations of sex of sender and gender of subject. Overall, the facial identification process was found to be very rapid (about a quarter of a second slower than identification of a simple geometric form) and accurate (.078 error rate).     

Looking Behavior and Smiling in Down Syndrome Infants

We studied the relation between direction of gaze and smiling in 15 typically developing infants and 15 infants with Down syndrome. All of them were videotaped during face-to-face interaction with their mothers at home, and while having access to their familiar toys. Results showed that mothers in the two groups behaved in a similar way; that Down syndrome infants looked at their mother's face for longer than typically developing children; and that the relationship between looking and smiling was similar in the two cases and reflected as an increase in the time the infant looked at its mother's face and a decrease in the time the infant looked at toys. It was deduced that Down syndrome infants are capable of distinguishing the differential significance of faces and toys, so that, in the same way as typically developing infants, they direct their affective behavior fundamentally towards the social element, which leads us to consider the affiliative function implied by this expression.     

Sexual Behavior Among Young Carers in the Context of a Kenyan Empowerment Program Combining Cash-Transfer,Psychosocial Support,and Entrepreneurship

This study examined associations between sexual initiation, unprotected sex, and having multiple sex partners in the past year with participation in a three-year empowerment program targeting orphan and vulnerable children (OVC). The Kenya-based program combines community-conditioned cash transfer, psychosocial empowerment, health education, and microenterprise development. Program participants (n = 1,060) were interviewed in a cross-sectional design. Analyses used gender-stratified hierarchical logit models to assess program participation and other potential predictors. Significant predictors of increased female sexual activity included less program exposure, higher age, younger age at most recent parental death, fewer years of schooling, higher food consumption, higher psychological resilience, and lower general self-efficacy. Significant predictors of increased male sexual activity included more program exposure, higher age, better food consumption, not having a living father, and literacy. Findings support a nuanced view of current cash transfer programs, where female sexual activity may be reduced through improved financial status but male sexual activity may increase. Targeting of OVC sexual risk behaviors would likely benefit from being tailored according to associations found in this study. Data suggest involving fathers in sexual education, targeting women who lost a parent at a younger age, and providing social support for female OVC may decrease risk of human immunodeficiency virus (HIV) transmission.     

Automated measurement of infant and mother Duchenne facial expressions in the Face-to-Face/Still-Face

Although still-face effects are well-studied, little is known about the degree to which the Face-to-Face/Still-Face (FFSF) is associated with the production of intense affective displays. Duchenne smiling expresses more intense positive affect than non-Duchenne smiling, while Duchenne cry-faces express more intense negative affect than non-Duchenne cry-faces. Forty 4-month-old infants and their mothers completed the FFSF, and key affect-indexing facial Action Units (AUs) were coded by expert Facial Action Coding System coders for the first 30 s of each FFSF episode. Computer vision software, automated facial affect recognition (AFAR), identified AUs for the entire 2-min episodes. Expert coding and AFAR produced similar infant and mother Duchenne and non-Duchenne FFSF effects, highlighting the convergent validity of automated measurement. Substantive AFAR analyses indicated that both infant Duchenne and non-Duchenne smiling declined from the FF to the SF, but only Duchenne smiling increased from the SF to the RE. In similar fashion, the magnitude of mother Duchenne smiling changes over the FFSF were 2–4 times greater than non-Duchenne smiling changes. Duchenne expressions appear to be a sensitive index of intense infant and mother affective valence that are accessible to automated measurement and may be a target for future FFSF research.
