This study was carried out to determine whether or not attachment would enhance our ability to predict the breakup of nonmarital romantic relationships. In phase one of the study, 217 introductory psychology students completed measures of attachment, satisfaction, investments, alternatives, commitment, length of current relationship, and asserts that commitment to a relationship will be greater to hundred thirteen of these individuals were contacted seven weeks later to follow-up on the status of their relationships. Fifty-four of these relationships had ended at follow-up. Through regression analyses, only moderate support was found for the investment model. This model the extent that an individual is highly satisfied, has invested heavily in it, and does not see his/her alternatives as particularly attractive. Contrary to predictions, than it was to the length of the of time spent associating with the attachment was found to be more strongly related to investments and commitment relationship or the amount partner. Whatever contribution attachment may have made to the prediction of breakup appears to have been suppressed by commitment, which was found to be the best single predictor of breakup. Finally, more women than men were found to be the initiators of the breakup of their relationships, but these differences were only marginally significant. / Department of Psychological Science

This thesis will discuss Pavlovian conditioning and its utility in researching various areas of psychology including interpersonal attraction. It was designed to extend the application of conditioning principles in the study of interpersonal attraction by testing cue competition predictions made by the reinforcement-context theory of attraction.

Mate preferences provide an opportunity to explore the validity of evolutionary and social role origin theories of sex differences in human behaviour. In evolutionary models, preferences are sex-specific adaptive responses to constraints to reproductive success. In social role models, sex differences arise from the allocation of men and women to different gender roles. I explored the effects of the status of women on preferences to assess the validity of the origin theories. I developed an adequate measure of female status (i.e. resource control), and explored its effects on female preferences in an online survey (Chapter 3), a mail-shot survey (Chapter 4), and a sample of non-industrial societies (Chapter 5). Results implicated a role of constraints on women in the expression of female-typical preferences. In an experimental manipulation of female perceptions of their status, results enabled greater confidence in the attribution of causal direction to relationships (Chapter 6). In Chapter 7, I explored the conditions under which the relationships of interest occurred. In Chapter 8, to further explore the origin models I investigated the effects of resource control on the magnitudes of sex differences in preferences. In Chapter 9, I explored relationships between a characteristic more closely related to the male gender role (i.e. apparent intelligence) and femininity in female faces. Women who were considered to look more intelligent were perceived as less feminine. In Chapter 10, I investigated the effects of reproductive strategy on mate preferences. Results were consistent with evolutionary models of behaviour. I argue that “status” is a multidimensional construct, and that its effects on mate preferences are complex, that while results were generally more consistent with an evolutionary than the biosocial model, integration of models would provide greater insight into human mate preferences.

The purpose of this study was to determine the physiological responses of subjects to an initial psychological interview, and to study the effect of physical proximity and touch on these responses. Heart rate and total skin conductance variability were the responses monitored. To assess the subjects' like or dislike of the psychologist interviewer, a measure of interpersonal attraction, the Interpersonal Judgment Scale, was employed. The California Psychological Inventory was utilized to investigate possible personality correlates with the physiological responses. Sixty females, between the ages of 18 and 28, responded to the California Psychological Inventory and were then connected to the physiological monitoring devices. The subjects' physiological responses were recorded for a 10-minute period in an empty office and then they randomly received one of the following treatments: In treatment I the psychologist entered the counseling office, introduced himself, and sat one foot from the subject while orally administering the Rotter Incomplete Sentences Blank--Adult Form. When the psychologist reached item 15 he stated, "Very good, now let's go on to page 2." After the test, the psychologist said, "That's all for today, thank you for your help. If you will wait here, the experimenter will be right in." The psychologist then left the office, and the subject responded to the Interpersonal Judgment Scale. Treatment II was identical to treatment I, except the subject was touched three times during the interview, once on the shoulder and twice on the arm. In treatment III the psychologist entered the office, sat behind a desk and followed the procedure outlined in treatment I. The results indicated that a subject's reaction to an initial psychological interview is a mild to moderate defensive response manifested by an increase in physiological stress levels. Total skin conductance variability increased significantly during the period when the psychologist was in the office. Heart rate increased in 54 out of 60 cases, but did not increase sufficiently enough in magnitude to justify significance. There were no significant differences between the three treatment groups on heart rate, skin conductance, or interpersonal attraction, and there were no personality correlates which were great enough to be of practical value. The data collected in the experiment supported the conclusion that a subject's reaction to an initial psychological interview is a mild to moderate stress response manifested by increments in physiological stress levels. Touch and physical proximity do not appear to alter the stress response or the subject's like--dislike attitude toward the psychologist.
