The object of this study was to investigate the relationship of various factors affecting the frequency and status of "dating" behavior. The techniques used were (a) a Subjective Survey, to obtain item possibilities for the Questionnaire and to define terms; (b) a specially constructed Questionnaire, to explore the relationship between a wide variety of personal characteristics of young people and their frequency and status of dating; (c) the Guilford-Zimmerman Temperament Survey and a separate section requiring each subject to report his "dating" behavior, to explore relationships between 10 personality traits and the frequency and status of dating. The findings may be divided into three sections. The Subjective Survey defined the terms "date" and "go steady" and established popular conceptions of the infrequent, frequent and "go steady" types of "dater". The Questionnaire findings found 46 separate items to be significantly related to frequency of dating. Briefly summarized the items could be classified under the following headings: (a) physical factors; (b) clothes; (c) automobiles; (d) active and passive activities (athletics, dancing, listening to jazz); (e) moral factors (smoking, drinking) and (f) previous "dating" experience. The Guilford-Zimmerman Temperament Survey and the special section on "dating" behavior found three traits, A-Ascendance, F-Friendliness, S-Sociability, significantly related to the frequency of dating in females; and two traits, G-General Activity and S-Sociability, significantly related to the frequency of dating in males. The writer's Theory of Normal-Neurotic Sexual Choice was formulated in an attempt to explain some unexplored areas in the field. / Arts, Faculty of / Psychology, Department of / Graduate

This thesis investigates the role of male vocalizations in two aspects of Pacific Tree Frog breeding behavior: Spacing out of males on breeding areas and selection of mates by females. Spacing out: An analysis of nearest neighbor distances of calling frogs showed that males space out more than if distributed randomly on the available calling sites. An addition experiment provided corroborative evidence that males tend not to call too close together; of equal numbers of frogs added to an empty (control) enclosure and an enclosure occupied by calling frogs, more subsequently called in the control. The species' "mating" call (D call), as well as attracting females, functions in spacing out; in an addition experiment, fewer frogs called in an enclosure occupied only by loudspeakers playing back D calls than in the control. Another vocalization (S call) seems to function only in spacing out. If two calling frogs come close together (less than ca. 50 cm), both usually begin making the S call. One frog may then move away; if not, physical combat may follow. I hypothesized that the S call is a stronger warning to nearby males than the D call. A playback experiment partially supported this hypothesis. I consider possible functions of spacing out, and suggest that males which maintain spacing may attract more females than they would otherwise, perhaps because females can more easily locate them. Mate selection: I attempted to test two hypotheses: First, females select large males on the basis of their low-pitched vocalizations (there is an inverse correlation between call pitch and body length). A comparison of body lengths and call pitches of males found in amplexus with a sample of males from the calling population did not support this hypothesis. Second, females choose males which initiate bouts of calling (chorus leaders). Both systematic field observations and a laboratory experiment support this hypothesis. Chorus leaders also end choruses, call at a faster rate during choruses, call more during periods not defined as choruses, and call louder than other frogs. In nature, females may also use these differences as cues in mate selection. The advantages of being a chorus leader should select for frogs calling all of the time, yet frogs show frequent lulls in calling. A playback experiment showed that frogs are less responsive (measured by latency to call) to stimulus calls shortly after having stopped calling than later in the lull period. I hypothesized that fatigue is responsible for this short-term waning of calling tendency. A respirometry experiment suggested (but quite inconclusively) that the fatigue hypothesis is feasible. / Science, Faculty of / Zoology, Department of / Graduate

The benefits of being average were examined within the context of romantic relationships by focusing on courtship progression and events for 164 married couples. The courtship progression was captured using a graph of the fluctuations in the percentage chance of marriage for each spouse from when couples first began dating up until the wedding day. Five factors were then used to capture the graph: Time elapsed to progress from 25 to 75% chance of marriage, turbulence in chance of marriage values, average change in percent chance of marriage between relationship events, courtship length, and the sum of squared deviations from a straight line connecting when couples first started dating until their marriage date. Couples also reported on the timing of important relationship events (i.e., meeting parents, first fell in love, first sexual intercourse, and engagement) that were then compared to the order of the average courtship event progression. Deviations from the average courtship in terms of either graphical or event indicators did not significantly predict whether or not couples divorced in the first 13 years of marriage. / text
