An Evaluation Of The Effects Of An Infant-Care Skills Training Program On Fathering Behaviors, G. Joseph Vrazo

Masters Theses

This study replicated the findings and expanded the assessment procedures of a previous study that had established the effectiveness of a multi-component infant-care skills training program for first-time fathers. A multiple probe design was used in this study to demonstrate that the training program produced criterion performance of the infant-care skills by four experimental fathers; also, an increase in the frequency of infant stimulation activities initiated by these fathers was observed. A pre/post training evaluation of the effects of the training program on the fathers' performance of play and affectional behaviors and daily infant-care activities yielded negative results. Four control …

Drug Use And Abuse: A Survey Of Mentally Retarded Citizens In Kalamazoo County, Michigan, Sandra Ann Burdick

Masters Theses

An abundant array of research in the area of drug use and abuse among various populations has been conducted in recent years. These studies have determined that although several demographic variables affect the prevalence of drug use, all segments of society who have access to drugs are at some risk. Whether relative risk is influenced by subaverage intelligence is unclear, however, for very little has been done to determine the prevalence of drug use and abuse among the mentally retarded.

In this survey methods were utilized to gather such information in Kalamazoo County, Michigan. A survey return rate of 73% …

The Effects Of Altruism On Activity Productivity In Elderly Women In Skilled-Care Nursing Facilities, Carol J. Getz

Masters Theses

This study investigated altruism as a factor in productivity in elderly women. Eight groups of institutionalized elderly women (n = 33) stenciled personalized (initials) stationery. Groups were randomly assigned to either the non-altruistic condition or the altruistic condition; there was control for time of day and location of the activity. Subjects in the non-altruistic condition made stationery for themselves, while subjects in the altruistic condition made stationery for abused children living in an innercity. The number of pieces of stationery produced and the duration of time engaged in activity were recorded for each subject. Mann-Whitney U tests revealed that subjects …

Hemispheric Brain Laterality Of Perception Of Tachistoscopically Presented Erotic Stimuli By Male And Female College Students, Randall Warne Stewart

Masters Theses

The effects of hemispheric asymmetry on the perception of erotic stimuli presented in either of the two visual fields was investigated. Freshmen and Sophomore college students, 20 males and 27 females, were used as subjects in the study. Subjects were bilaterally presented with combinations of erotic, neutral, and blank visual field stimuli using a "split visual field" procedure for a total of 96 200 msec. presentations. Subjects were asked to rate the presentations on a scale of 1 to 5; 1 was equal to neutral and 5 was equal to very erotic. Males and females rated erotic stimuli presented in …

An Attendance Incentive Procedure Using Group Contingencies, Norman Kevin Brown

Masters Theses

This study used a multiple baseline design to examine the effect of a lottery-based group contingency on unscheduled sick leave (USL) use by residential treatment workers. Sixty direct-care workers participated in this study. Researchers employed a group contingency that required workers to meet 2-week absence criterion levels in order to participate in a subsequent reinforcement lottery. The workers who won the lottery chose one of four rewards including 20 dollars, 4 hours paid time-off, lunch with a supervisor, and four movie tickets. The mean number of USL hours used in each of five work units was reduced significantly during intervention. …

A Comparison Of Retail Sales Performance Under Individual And Group Quota Systems, Karen Beth Bishop

Masters Theses

The research goal of this study was to determine if changing from an individual to a group quota system changed variability in sales performance. Data were collected within three branches of the company. Within subject and within group variances were calculated using salesclerk's sales figures. Three months of 1986 represented individual quota figures, while the same three months of 1987 represented group quota figures. Results of the within group variance found two departments had a variance decrease and one department had a variance increase. Cumulative sales for both systems found decreases in sales using the group quota system for two …

Minimizing Stimulus-Reinforcer Contributions To Operant Latency, Mario Miguel Delgado Zambrano

Masters Theses

The present study involved two experiments using an unlighted food hopper. The first provided magazine training with the darkened hopper, followed by a test for autoshaping potential. The second, using birds that showed very little autoshaped behavior in the first experiment, and continuing to use the unlighted hopper, measured operant latencies in a Hesse (1984) discrete-trial multiple schedule using a two-key procedure for separating stimulus-reinforcer and response-reinforcer contributions. The objective here was to demonstrate latency differences between favorable and unfavorable schedule components, while limiting the possible confound of stimulus-reinforcer contributions as measured by initial stimulus-key responding.

Despite being unable to …

The Effects Of Magnitude Of Extrinsic Reinforcement On Intrinsic Interest: An Experimental Analysis, Brian Howard Gribler

Masters Theses

The present study examined the effect that three magnitudes of extrinsic reinforcement had on wheel running following the termination of reinforcement. After an initial baseline period, three groups of rats were assigned to one of three conditions: a variable interval 60 second schedule of reinforcement, a variable time 60 second schedule of reinforcement, or a control condition. Each subject in the reinforcement groups was exposed to three different magnitudes of reinforcement. Each reinforcement phase was followed by a return to baseline. The results indicated that contingent reinforcement increased wheel running although rates were comparable for all magnitudes of reinforcement. No …

The Effects Of Music Videos On Adolescent Females Self-Concept And Body-Image, David Scott Eggli

Masters Theses

Music videos are a phenomenon of the 1980s. Their striking imagery, flashy choreography, sexy clothing, and quick cuts have attracted a huge audience of adolescents and changed the face of the fashion industry. If rock stars and music videos can attract millions of teenage viewers and change the style of clothes worn, they may also affect a teenager's self-concept and body-image.

The subjects in this research project were 18 adolescent females between the ages of 12 and 17. The subjects viewed either music videos or G-rated movies. The Piers Harris Children's Self-Concept Scale served as the dependent variable for pretest …

A Study-Support Program For High-Risk, Black College Freshman Enrolled In A General Psychology Course, Angela Michelle Williams

Masters Theses

As a replication of Jackson's (1984) work, this research compared the performance of three groups of college freshmen. The groups consisted of black, high-risk students who voluntarily enrolled in a study-support group because of their initial quiz scores. The support program required the students to study each week's psychology objectives in four smaller segments, rather than studying all the week's material at once. The assumption was that this would increase the students' contact with the study material and improve their performances. An ABA design was used. The participants in the support program received higher quiz scores and final grades than …

Increasing Appropriate Behavior Using Antecedent Physical Exercise In Mentally Retarded Adults, Steven Degroot

Masters Theses

In order to ascertain if aerobic exercise would facilitate task performance, two mentally retarded adults exercised five days a week and performed three discrimination tasks three days a week. Baseline performance was determined for the two subjects on the tasks which involved shape discrimination, picture discrimination, number discrimination, and sequencing. After their baseline performance was determined, the participants began an exercise program which worked toward increasing their pulse rates to an aerobic level (150% of resting pulse). Subsequently, the subjects performed the discrimination tasks immediately after exercise. After this intervention period, baseline performance was again determined. The results indicated that …

Assessment And Training Of Visual And Tactual Stimulus Equivalence, Brooke Ann Rigney

Masters Theses

Visual-tactual equivalence was examined within the stimulus equivalence paradigm originally developed by Sidman in studies of verbal behavior (1971). Experiment I assessed for equivalence between tactually and visually presented objects. In Experiment II, colors and textures were added to the objects and the effect of modality distinctive stimuli on equivalence was examined. Experiment III then studied the establishment of equivalence with these modality distinctive stimuli using the Sidman stimulus equivalence paradigm.

Visual-tactual equivalence was demonstrated in Experiment I. Experiment II demonstrated that equivalence could be disrupted by modality distinctive stimuli. Experiment III then showed that equivalence could be demonstrated between …

Responding Under Homogeneous Versus Heterogeneous Chained Variable-Interval Schedules, Stephen P. Starin

Masters Theses

Four pigeons responded under chained variable-interval schedules in which the required response topographies were either similar [i.e., a homogeneous chain] or dissimilar Ci.e., a heterogeneous chain]. Subjects were exposed to all possible combinations of initial-link key pecking or treadle pressing and terminal-link pecking or treadling. Three of four subjects displayed higher initial-link response rates under the homogeneous chains. The present results were explained in terms of an induction effect in which the strengthening effect of reinforcing a particular terminal-link response topagrapahy generalizes to similar responses earlier in the chain, but not to topographically different responses.

The Effects Of Methsuximide And Mephenytoin On The Repeated Acquisition Performance Of Pigeons, Dawn D. Delaney

Masters Theses

Learning impairment is a potentially serious side effect of antiepilepsy medications. The present study investigated the effects of methsuximide and mephenytoin on learning in pigeons performing under a repeated acquisition procedure. Given acutely, methusuximide (25, 50, 75, 100 mg/kg) and mephenytoin (60, 120, 240 mg/kg) produced generally dose-dependent decreases in rates of responding; increases in percent errors were largest at doses that produced the greatest decrease in response rate. An analysis of the within-session distribution of errors revealed that certain

Family Problems In The Background Of Mental Health Professionals, Linda Elaine Mccarter

Masters Theses

It has been proposed by some that students choose to study in mental health related fields in an effort to find solutions for their own personal emotional or family problems. Some believe that those who assumed or were assigned a family role of the good or parentified child (a role which requires that the needs of others be placed ahead of one's own) are over-represented among mental health professionals. Others contend that there are no significant differences in family background between psychotherapists and other individuals with a similar level of education. Little empirical investigation has addressed these issues. Studies which …
