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.

The City of Denton Pecan Creek Wastewater Treatment Facility has periodically failed effluent toxicity testing. A Toxicity Identification Evaluation has determined that Diazinon in the effluent is contributing to the observed toxicity. Chlorpyrifos is also implicated as a factor. The City of Denton constructed a half acre experimental wetland to remove Diazinon related toxicity. Results from spiking and microcosm experiments indicate that the wetland can reduce the Diazinon.

Two years before impoundment, the trophic status of Lake Ray Roberts was predicted by applying the total phosphorus input into the Organization for Economic Cooperation and Development (OECD) eutrophication model. Predicted mean summer epilimnetic (MSE) chlorophyll a of Elm Fork arm, Isle duBois arm and Main Body were in the eutrophic category of the OECD model. Observed MSE chlorophyll a two years after impoundment of Elm Fork arm, Isle duBois and Main Body had not reached their predicted means and were at the mesotrophic-eutrophic boundary of the OECD model. Six years after impoundment, observed MSE chlorophyll a for Main Body, was closer to its predicted mean and in the eutrophic category of the OECD model. Six years after impoundment, Elm Fork arm was the most productive area of Lake Ray Roberts. Observed means of chlorophyll a, total phosphates, suspended solids and turbidity were often highest in the Elm Fork arm. Wastewater effluent from Gainesville and Valley View, TX, had an impact on productivity in Elm Fork arm.

Using the "revealed operant" technique, variability during acquisition and extinction was examined with measures of response rate and a detailed analysis of response topography. During acquisition, subjects learned to emit four response patterns. A continuous schedule of reinforcement (CRF) for 100 repetitions was used for each pattern and a 30 min extinction phase immediately followed. One group of subjects learned the response patterns via a "trial-and-error" method. This resulted in a wide range of variability during acquisition and extinction. Only one subject emitted a substantial amount of resurgent behavior. A second group of subjects was given instructions on what keys to press to earn reinforcers. This group had less variability in acquisition and extinction and resurgent responding was prevalent.

This study used the Health Belief Model to examine the predictors of AIDS preventive behavior. The independent variables were the variables of individual perception, modifying factors (psychological variables), and likelihood variables. The respondents, the Taiwanese students of the University of North Texas, were influenced both by Chinese sexuality and Western values in their AIDS-risk behavior. The results revealed that 90% of the respondents were misinformed on the availability of AIDS vaccine. In addition, a majority of the students were either abstaining from sex or practicing monogamy. Using Pearson's correlation coefficient and multiple regression analysis, this study found that the psychological variables rather than cognitive variables significantly influenced the respondents' AIDS preventive behavior. Finally, suggestions were made for future research on AIDS, and for AIDS preventive behavior campaigns.

Research shows that human operant behavior typically differs from non-human operant behavior on schedules of reinforcement. These differences in performance may be related to differences between the experimental preparations used to study human and non-human operant behavior. One such difference is the type of reinforcer used. This experiment analyzed the differential effects of points alone, points backed up by money, and sounds on schedule performance of human subjects. Results show that sounds generated moderate rates of responding, capable of change in either direction. When points backed up with money were the reinforcers, however, high rates of behavior were generated, disrupting the previously established baseline performance. This suggests that while points may be effective in generating high rates of behavior, they may be ineffective in producing sensitive baselines needed to study human operant behavior on schedules of reinforcement.

This thesis examined student-participants' self-reported use of romantic relational maintenance strategies and their partners' reports of relational satisfaction. Additionally, individuals outside the romantic relationship reported on student-participants' general communicator style. The research proposed that general style reports would be predictive of relational maintenance strategy usage and of romantic partners' relational satisfaction. The study found that general style behaviors may not be indicative of relational maintenance strategy usage or romantic partners' relational satisfaction. Tests of sex differences revealed that females' expression of various relational maintenance strategies and style behaviors are associated with male partners' relational satisfaction; however, no results were obtained indicating specific behaviors expressed by males result in female partners' relational satisfaction.

The role of point loss for symmetrical relations introduced simultaneously with probe trials in the absence of original relations on all probe trial performances was evaluated. Training was completed after six conditional discriminations were established in two contexts. Point loss was introduced simultaneously with probe trials in the absence of original relations in the first context. Probe trials with no point loss in the absence of original relations were introduced in the second context. The simultaneous introduction of probe trials and the point loss contingency may in some cases prevent the emergence of an equivalence class in the context that contained the point loss as well as in the context where no point loss occurred.

Parental socialization values are compared over sixty years by using data from the Denton Parent Project collected in 1989 and from similar questions asked of parents in Middletowri in 1924 and 1978, The objectives of the study were as follows: how have parental socialization values changed through time since the 1920s; has the impact of parental social class status on parental socialization values decreased over time; compare Alwin's study on obedience and autonomy to see how trend has changed from 1978 Middletown to 1989 Denton; and, finally, look at certain family structure variables to determine their influence. Today's parents emphasize social acceptance and a sense of social responsibility in child training practice. Social class still has an impact on parental socialization values but not as great as expected.

This study explored the inferences male children held about the brand personality. The sample included 46 male fifth graders. Personal interviews were conducted and the results were compiled and interpreted using descriptive statistics. Four subject areas were addressed: identification and inferences about brand personality, sources of inferences, children's ability to make inferences about other children based on brand personality, and application of brand personality to self. Results indicated children make inferences about brand personality, make inferences about other children based on brand personality, and apply brand personality to themselves. An attempt to identify sources of inferences was inconclusive.

Thirty-three children from a community sample, ages 5 to 13, were administered the Rorschach Inkblot Test, along with projective Draw-an-Animal and Draw-a-Person tasks and other psychological measures. Subjects were randomly assigned to one of three test order conditions: Draw-an-Animal followed by the Rorschach, Draw-a-Person followed by the Rorschach, and Rorschach before any other projective test. The number of Human and Animal contents in the test records was examined. Analysis showed no significant differences among the three groups for production of the content variables, suggesting that the Rorschach Inkblot Test is relatively robust with respect to test order effects.

The banquet staff at a north Texas hotel were responsible for setting up 11 different functions (e.g., buffet dinners) for conferences and meetings. The functions were often set up late and items were often omitted. An analysis suggested that performance problems were the result of weak antecedents, inefficient work procedures, inadequate training and a lack of motivating consequences. An intervention consisting of task checklists, feedback, goal setting, monetary bonuses, training and job aids was designed to enhance the accuracy and timeliness of function setups. Performance increased from an average of 68.8% on the quality measure (accuracy plus timeliness) in baseline, to 99.7% during the intervention phase. Performance decreased to 82.3% during a follow-up phase in which parts of the intervention were discontinued by hotel management. Performance increased to 99.3% with the reintroduction of the intervention phase.

A Magical Contagion and AIDS Scale was developed to address problems with existing Contagion and AIDS measures. Magical Contagion is an influence that exists after contact is terminated. It is comprised of Permanence, Holographic Effects, Moral Germ Conflation and Backward Action. Data from 280 undergraduates revealed low mean levels of Magical Contagion and AIDS. Contagion effects did not differ on demographic variables. Content validity, criterion-related validity, discriminate validity, and internal consistency were evaluated. Significant correlations were found between the Contagion Scale and Merging/Separation and Homophobia Scales. Negative correlations were found between the Contagion scale and the AIDS knowledge and social desirability scales. Alpha reliabilities were high (a > .93) for the Contagion scale and subscales. Factor analysis suggested the existence of a single factor and mixed support for three factors.

Six hundred sixty-six students were queried at the University of North Texas. The appropriate use of nonverbal behaviors of international and U.S. American TAs was surveyed. An eleven item questionnaire (Teacher Nonverbal Measure) was utilized. These questions were tested by an ANOVA. Data indicated that international TAs are less likely to use appropriate nonverbal behaviors than U.S. American TAs. Thus, it is possible to assume that international TAs are more likely to be perceived as using inappropriate nonverbal behaviors than U.S. American TAs. Also, communication competence was investigated. The Communication Skill Rating Scale was utilized and tested by ANOVA. Results indicate that international TAs are viewed as significantly less competent than U.S. American TAs.

Documentation of social impacts resulting from the construction of Lake Ray Roberts is to be incorporated into a two year post-impoundment study. Research objectives are to: 1) locate current residences of landowners and previous landowners who were displaced; 2) determine social impacts resulting from construction of Lake Ray Roberts; 3) document degree of satisfaction with current living conditions; 4) document landowners' degree of satisfaction associated with COE negotiations; 5) document landowners' observations. Landowners were identified by telephone and sent a mail-back questionnaire. Respondents were generally happy with current residences and communities. While courtesy and sufficient information were provided by the COE, respondents would have preferred for property settlements to be more consistent and timely.

Two continuous performance tests were administered to normal adult subjects. The mode of presentation (visual or auditory) and the type of task (vigilance or distractibility) were varied, and their effects on performance measured. Data were collected on eighty-two subjects, and results indicated that auditory presentation of stimuli increased the difficulty of both tasks. Results also suggest that the distractibility task administered in either mode was more difficult than the vigilance task. Intercorrelations among the four continuous performance tasks are provided. Normative data are presented on all four tasks administered. A measure of symptoms of attention-deficit disorder in adults, the Adult Behavior Checklist, was found to correlate significantly with another measure of pathology, the SCL-90-R.

The use of scales on the Personality Assessment Inventory (PAI) to detect defensiveness in criminal and nonclinical samples was evaluated. Forty-five male inmates of a county jail and 38 male undergraduate psychology students were provided with incentives to complete the PAI under two conditions: standard instructions and experimental instructions to feign a specific, positive role. The sequence of instructions was counterbalanced in both samples for the purpose of examining ordering effects. A repeated measures multivariate analysis of variance (MANOVA) was performed, yielding significant main effects of condition, group and order. Additionally, a step-wise discriminant function analysis significantly predicted group membership (i.e., subjects under honest and faking conditions) with a hit rate = 84.4%. Finally, a more effective cutting score for the Positive Impression scale was recommended.

The primary research questions dealt with whether parents consider different personality characteristics of importance for boys and girls. Data were collected by conducting a telephone survey of a random sample of parents in the city of Denton with children under the age of eighteen living in the household. Respondents were asked whether they considered the personality characteristics of responsibility, strict obedience, being respectful of the opinions of others, showing good manners, being independent, and having loyalty to a religion not important, somewhat important, or very important for boys and girls. Of the respondents fifty-nine were fathers and one hundred and twenty-one were mothers. The analysis of the data revealed that mothers and fathers have similar attitudes concerning the importance of these personality characteristics.

Mental imagery is a common theme in research that clarifies how musical thought relates to musical performance. Unfortunately, minimal information exists regarding mental imagery and singers. The purpose of this study was to probe the role, if any, mental imagery plays in the conceptualization of pitch and vowel. By interviewing singers at differing levels of expertise, basic information was obtained about the mental processes used by singers. Through evaluations of the singers' mental processes, it was concluded that 95% of the singers in the study employed mental imagery. All singers described using kinesthetic imagery, while the majority implemented sensory and auditory imagery. Viso-spatial imagery was implemented among the more experienced singers. The majority of singers also reported: imaging pitch and vowel interactively; imaging from an internal perspective; and utilizing mental rehearsal. Less than half of the singers described using methods other than mental imagery to conceptualize pitch and vowel.

Differences in college student's psychological well-being, extrapunitiveness, and intropunitiveness were related to the presence or absence of maltreatment during childhood years, and its acknowledgement by the student. Subjects were 56 male and 85 female undergraduate students at the University of North Texas. Subjects were given structural scale v.3 of the California Psychological Inventory (CPI), the Extrapunitive (E), and Intropunitive (I) indices of the Hostility-Direction of Hostility Questionnaire (HDHQ), and the Physical Punishment scale (PP-scale) of the Assessing Environments Questionnaire (AEIII). Results indicate no significant differences in psychological well-being, extrapunitiveness, or intropunitiveness, which would be explained by the presence of maltreatment or its acknowledgement.

One problem facing the hospitality industry today is turnover. Management turnover rates of 50 and 75 percent continue to plaque all segments of the industry. Personality type theory holds that people are happier in environments that are compatible with their personalities. This study examines 229 undergraduate students enrolled in hospitality education at the University of North Texas. The Myers Briggs Type Indicator was administered to these students to determine their predominant personality types, and to compare these types to those desired by hospitality industry professionals for success within the industry. Variables such as gender, work experience, and classification were also examined in comparison to student personality types.

The current study examined if students' levels of social physique anxiety vary depending on the type of exercise setting they select. The study determined the degree to which social physique anxiety changed over the course of semester-long involvements in different exercise settings.

This study evaluated the effects of chlorinated effluent discharged from the City of Denton, Texas' wastewater treatment plant on Pecan Creek's fish and macroinvertebrate assemblages, and their recovery upon dechlorination. A baseline of ecological conditions was established while chlorine was present in the effluent (June 1993- October 1993), and was evaluated again after dechlorination with sulfur dioxide (October 1993-August 1994). In situ Asiatic clam and fathead minnow ambient toxicity tests, and fish and macroinvertebrate collections were used to establish this baseline for comparison to post-dechlorination results.
