One hundred and twenty six undergraduates were cast into a supervisory role in which they worked with a subordinate (confederate) for two twenty minute work sessions. Subjects were placed into one of nine conditions. Subordinate reaction (positive, negative, or none) and subsequent performance (increased, decreased, or same) were manipulated by the confederate. Both reaction conditions were predicted to influence a leniency bias in the supervisor's rating behavior, and either increase (negative reaction), or decrease (positive reaction) amount of supervision. Also, supervisors exposed to the positive reaction were hypothesized to provide more self attributions, while supervisors in the negative reaction group should tend toward greater self-serving attributions. In addition, supervisor response to interpersonal attraction, conflict avoidance, and uncertainty scales were obtained. Both ratings and amount of supervision measures failed to yield significant results. Partial support was found for the attribution hypothesis, and differences on the interpersonal attraction scales were obtained for the experimental reaction conditions. Implications of the results and suggestions for possible research are discussed. / Master of Science

Previous research indicates that women are judged on the amount of food eaten and that both men and women are judged on the type of food eaten. This study is an attempt to determine whether meal size or type predominantly accounts for these findings on the variables of masculinity, femininity, attractiveness, thinness, fitness, and likability. Physical activity was also included to determine its effect on these variable. Subjects used were 313 undergraduate students. Results indicate that meal type is more influential than meal size and that physical activity significantly influences judgements of others. The results are discussed in terms of future research and relatedness to socio-cultural theories of eating disorders.

With the capacity to connect millions of singles through the virtual world, online matchmaking has altered the traditional, face-to-face romantic relationship initiation process. Users of online matchmaking sites have easy access to thousands of available singles and can communicate with partners before ever meeting face-to-face. Specific mechanisms by which online matchmaking environments operate are likely to distort both users’ appraisals of other users and users’ appraisals of themselves. This phenomenon in dating has left researchers to speculate about the effectiveness of romantic relationship initiation in such a context, and for relationships that are successfully formed online, whether the effects of online matchmaking extend beyond the relationship initiation process to influence the subsequent progression of romantic relationships. Seventy-five single men and women were recruited and agreed to subscribe to the online matchmaking site Match.com for 30 days. Participants completed measures assessing their individual background characteristics, sociosexual orientation, personality and attachment. In the event that participants scheduled a first date with someone they met through Match.com, they completed pre and post-date measures assessing idealistic distortion of, attention to, and ease of finding alternative dating partners. Upon completion of their 30 days in the study, participants completed a follow-up questionnaire assessing the degree to which they idealistically distorted themselves to other users and their overall satisfaction and experience using Match.com. Logistic regression analyses revealed that the more users’ distorted the vitality and attractiveness of dating partners the less likely users were to experience a second date initiated by the dating partner. Future studies need to consider that traditional models of relationship initiation are out-dated and not applicable to the study of relationship initiation and progression in the context of online matchmaking. Relationship researchers need to investigate: gender differences in filtering potential partners, the function of filtering in such a context, the developmental progression of filtering and the subsequent potential heightened importance of physical attraction verses the importance of compatibility in predicting relationship initiation in the online matchmaking environment. Additionally, future research should involve comparisons of various matchmaking services’, should utilize larger sample sizes and should follow participants for a longer period of time. / text

College student men (n = 185) and women (n = 244) rated how desirable certain characteristics are in an ideal sex partner within a long-term relationship. They reported personal beliefs and predictions about the other gender's preferences. Of the twenty-six items that comprised each measure, factor analyses yielded five subscales: Communication/Openness, Physical Attractiveness, Knowledge/Skill, Take Control, and Response/Drive. As hypothesized, men placed greater emphasis than did women on Physical Attractiveness and Response/Drive, whereas women, more than men, believed Knowledge/Skill was important. Men and women differed completely on what they thought was important to each other. Furthermore, men recognized that there were gender differences on all subscales but Knowledge/Skill, whereas women recognized gender differences on all subscales. When the actual responses of men and women were compared with the beliefs that each had about the other, results showed that both genders underestimated the importance the other placed on Communication/Openness and overestimated that of Physical Attractiveness. Results are discussed with regard to implications for counselors. / Department of Psychological Science

For humans and non-human primates (NHPs) the face represents a particularly important source of social information providing a means of conspecific recognition and cues to personal details including sex, age, and emotional state. The human face may also be fundamental in the transmission to conspecifics of other forms of socially relevant information including the display of facial traits associated with sexual attraction and mate choice. A wealth of experimental literature indicates that humans display robust preferences for certain facial traits associated with facial attractiveness including preferences for bilateral facial symmetry, facial averageness and sexually dimorphic faces and facial features. It is thought that these preferences have evolved via sexual selection, and may be adaptive, due to the role that these specific facial features play in reliably signalling to others the possession of heritable genetic quality or ‘good genes’. Therefore, from an evolutionary perspective, it is possible that certain facial preferences may represent an evolutionary adaptation for the selection of potential mate quality. However, despite similarities between human and NHP face processing and recognition abilities, the shared evolutionary history and social importance of faces to primates in general, and the potential importance of these preferences in the mate choice decisions of NHPs, very little research has investigated the extent to which NHPs display comparable preferences to humans for these specific facial traits. Consequently, the aim of the following thesis was to comparatively assess the general and more specific preferences that humans and NHPs display for faces and for traits associated with facial attractiveness. Data was compiled from preference studies examining the visual preferences displayed by two species of NHP (brown capuchins (Cebus apella) and chimpanzees (Pan troglodytes)) for conspecific faces manipulated for those facial traits associated with attractiveness, and from a single study of brown capuchins examining their general visual preferences for various types of facial information. Comparative preference studies were also conducted upon human adults and infants examining the visual and declared preferences that they display for manipulations of facial attractiveness. Data showed that despite possessing general preferences for certain faces and facial information, generally NHPs displayed no significant preferences for those facial traits thought to influences judgements of attractiveness in humans. Possible reasons for this absence of preference for these particular facial traits and the evolutionary implications of these findings are discussed.

Based on linear models, this study demonstrated that the psychological and social structures of the classroom, viewed as a naturalistic human system, impact learning outcomes. To operationalize learning outcomes, final grades in the course and a subject self report scale tapping perceptions of utility of material taught were used. The social and psychological structures of the classroom-as-a-human-system were operationalized through the following variables: the degree of social integration of each student, based on network analytic procedures; communication apprehension of students; dimensions of perceived credibility of instructors; dimensions of interpersonal attraction to instructors; perceived satisfaction with task demands of the course; and adjusted orientation to communication, based on communication apprehension scores and network data. Data were obtained from five sections of a multi-section communication course of a large state institution of higher learning in the southwestern region of the United States. Differences in sex were not found.

In economic games the facial attributes of counterparts bias decisions to trust and decisions to enter play. We report research supporting hypotheses that trust and reciprocation decisions in trust games are biased by mechanisms of sexual selection. Hypotheses that trust game behaviour is modulated by inter-sexual competition were supported. 1) Attractive individuals elicit more cooperation. 2) Male participants display trust and reciprocation toward attractive female counterparts in excess of perceived trustworthiness (and this display is modulated by male self-reported physical dominance). 3) Female participants appear to respond to male trust as a signal of sexual interest and are therefore more likely to exploit the trust of attractive males. 4) In explicitly dating contexts females are more likely to prefer attractive males to pay for the meal. These results indicate that participants are biased by mate choice and mating display considerations while playing economic games in the lab. Hypotheses that trust game behaviour is modulated by intra-sexual competition for resources were also somewhat supported. 1) Male participants reporting an ability to win fights with same-sex peers are more exploitative of other males. 2) Cues to current circulating testosterone level in counterpart’s faces are less trusted but elicit more reciprocation. 3) The male sexually dimorphic trait facial width-to-height ratio (a trait which is related to both aggression and dominance) is related to an increased proportion of decisions to exploit others in the trust game while also being used by others as a cue to untrustworthiness. We conclude that trusting and trustworthy behaviour in both sexes is biased by mating market considerations predicted by intra- and inter-sexual selection.

60 undergraduate students evaluated male and female counselors on fifteen counselor variables based on listening to a tape recording of a counselor self-introduction paired with an attractive or unattractive picture. Two groups served as control groups; they heard the tape but received no picture. The attractive counselor was perceived as significantly more decisive, interesting, caring, open-minded, likable and better adjusted than the unattractive counselor. These effects were more pronounced for the female counselors than for the male counselors.
