Motivational Effects On A Psychometric Measure Of Prefrontal Brain Functioning In Patients With Chronic Schizophrenia And Related Disorders, Paul C. Smith

Dissertations

This study compared multiple sequential performances on a computerized version of the Wisconsin Card Sorting Test (Grant & Berg, 1948; Harris, 1986) by adult men receiving institutional inpatient treatment for chronic schizophrenia and related disorders. Participants were exposed to differential test conditions of minimal post-session non-contingent token reinforcement (baseline phases) and enhanced intra-session performance-contingent token reinforcement (experimental phase). Each major participant resided at the same continuing treatment unit at Kalamazoo Regional Psychiatric Hospital receiving similar social therapies but idiosyncratic psychotropic medication regimens, changes in which were tracked in relation to test performances. A simple single-subject reversal design was employed with …

Preventive Dental Care- Instruction And Contingency Management In The Acquisition And Maintenance Of Oral Hygiene Skills, Sandra K. Kallstrom

Masters Theses

Inadequate oral hygiene is one of the largest problems facing the dental profession to date. It is estimated that 98% of individuals suffer from dental problems associated with neglect. The objective of this study was to develop effective techniques which aided in the acquisition and maintenance of oral hygiene skills. This study compared the effects of instruction and demonstration with contingency management on plaque percentage scores. A between-subjects design was used with one control and three experimental groups. The results indicated that, oral hygiene instruction and demonstration appear to be ineffective in reducing plaque scores. Significant plaque reductions where found …

Religious Commitment As A Predictor Of Health Behavior And Health Status In A Selected Population, Donald George King

Loma Linda University Electronic Theses, Dissertations & Projects

Religious beliefs and behaviors are multidimensional and they profoundly determine the ways we respond to health and illness, suffering and death. Researchers have designed numerous scales to measure different dimensions of religious commitment, beliefs and behaviors. A thorough review of the literature has shown general relationships between religion and health, but no researcher has developed an instrument measuring dimensions of religious commitment specifically relevant to health behaviors.

In this study, scale items were developed to measure three dimensions of religious beliefs thought by Kenneth Vaux (1976) to be related to health behavior--purity of life, peace in existence, and belief in …

Effects Of Age On Motor Preparation And Restructuring, Paul Amrhein, Noreen Goggin, George Stelmach

Department of Psychology Faculty Scholarship and Creative Works

Age-related decrements in motor plan restructuring were investigated. In this experiment, older and younger adults performed a discrete aiming task that involved responses that were precued and responses that were modified at the time of an imperative signal. On 75% of the trials, the precue specified the response-stimulus (valid trials) with respect to the movement parameters of the arm (left or right) and direction (toward or away). On the remaining 25% of the trials, the response-stimulus was different from the precue (invalid trials) in that the subject was required to modify a planned movement by changing the arm to be …

The Effects Of Spouse-Based Cognitive-Behavior Therapy On The Treatment Of Agoraphobia, Joan Woods

Dissertations

The purpose of this clinical research was to determine whether spouse-supported treatment of agoraphobia would result in greater improvement on measures of exposure and avoidance than would individual treatment or no treatment. It was hypothesized that Couples Treatment subjects would demonstrate a significantly greater change from pretest to posttest than would Individual Treatment subjects or No-Treatment Control subjects. The study further predicted that significant improvements would be demonstrated for both treated groups on the same outcome measures, pretest to posttest and from pretest to follow-up.

Total N was 10 subjects, all were agoraphobic, married, and female, with 4 in Couples …

Depression In Caregivers Of Alzheimer’S Patients: Concurrent Validity Of Two Depression Scales, Joyce Sutton

Masters Theses & Specialist Projects

Forty-five male and female family caregivers of institutionalized and noninstitutionalized Alzheimer’s Disease patients were assessed for depression, using the Beck Depression Inventory (BDI) and Geriatric Depression Scale (GDS). Internal consistency and concurrent validity for the BDI and GDS were acceptable, based on item-total correlation, coefficient alphas, and a Pearson’s Product-moment correlation. A stepwise multiple regression analysis was carried out to determine which variables predict depression in Alzheimer’s caregivers. Using the traditional cut-off score of 11 for each scale, it was found that 42% were depressed on the BDI, while 58% were depressed on the GDS; these rates were not significantly …

The Effects Of Nonnutritive Sucking On The Behavior Of Premature Infants, Jean Newbold

Loma Linda University Electronic Theses, Dissertations & Projects

This quasi experimental study explored the effects of nonnutritive sucking opportunities on the premature's behavioral habituation, orientation and state control using the Mann-Whitney U-Test. The problem was to determine if experimental infants receiving regular nonnutritive sucking opportunities would show a difference in behavior when compared to a control group.

The sample was a purposive convenience sample of 15 infants. All infants were between the conceptual age of 28-34 weeks and were considered "stable" infants. Neurological examinations, consisting of selected segments of the Brazelton Newborn Behavioral Assessment Scale (BNBAS), were performed on all infants on the day of entry into the …

The Effect Of Interpolated Continuous Reinforcement Following Variable Ratio Reinforcement On Resistance To Extinction, Christine Miara

Graduate Theses

The effect on response rates during extinction of interpolating seven continuous reinforcement sessions after varying numbers of VR-25 sessions was investigated. Rats received either seven, fourteen, or twenty-one sessions of a VR-25 schedule followed by seven sessions of continuous reinforcement. There were three rats in each group. The rats then experienced seven sessions of extinction. All sessions were 30 minutes long." The results showed that rats that received the VR-25 schedule for 21 sessions made the roost responses over the seven extinction sessions. * Rats that received seven sessions of VR-25 made the least number of responses during extinction. The …

The Relationship Between Drinking And Assertiveness In College Students, Ernest Small

Masters Theses & Specialist Projects

The relationship between drinking patterns of college students and their measured level of assertiveness was examined in this study. The subjects were categorized into six groups based on their self-reported frequency and amount of drinking. They were also asked to record the number of drinks they had drunk in the prior week. The MacAndrews Alcoholism Scale and the Rathus Assertion Schedule were administered to all the subjects. Pearson Product-moment correlations were calculated to assess the relationship between levels of drinking, the number of drinks in the prior week and scores from the Rathus Assertion Schedule and the MacAndrews Alcoholism Scale. …

Locus Of Control, Knowledge Of Ethics, And Perceived Ethicality As Influenced By An Authority Figure, F. Matthew Mihelic, William G. Connolly

Faculty Publications

The present study investigated the relationship between a subject's locus of control, knowledge of psychological ethical research principles, and perceived ethicality of a psychological research proposal as influenced by an authority figure. Subjects were asked to judge the ethicality of a research proposal, which half were led to believe had been previously deemed unethical by an authority figure. No mention was made of the authority figure's viewpoint to the other subjects. The major finding was that the variability in ratings in ethicality of the research proposal tended to diminished from the no mention to the rejection manipulation in those of …

An Investigation Of The Behavioral Effects Of Methylphenidate Hydrochloride On Schedule-Induced Polydipsia In Rats, Linda Sederquist Smith

Masters Theses

The influence of methylphenidate hydrochloride injections on six male Charles River rats displaying schedule induced polydipsia was examined in this study. Bar pressing, licking, and water consumption were measured during a total of 63 daily one hour trials conducted with a variable interval 60-second schedule of bar pressing for pellets with water constantly available. The polydipsic response was acquired by subjects during the first 28 trials. Subjects were then divided into experimental and control groups. The experimental subjects recieved a 1 mg/kg injection of methylphenidate prior to regular trials 29-49 and extinction trials 50-63. Control subjects were injected with a …

State-Dependent Learning As A Function Of The Temporal Relationship Between Noncontingent Footshock And Electroconvulsive Shock, T. Scott Shutt

All Master's Theses

Rats were given a noncontingent footshock followed at various intervals by electroconvulsive shock. Twentyfour hours later they were trained on a non-shock passive avoidance task and tested for retention 72 hours later. When the interval between NCFS and ECS was short the animals showed an amnesia which reduced as the interval was lengthened. An interval of .5 seconds produced the most pronounced amnesia and intervals greater than 10 seconds produced virtually no amnesia. The results were consistent with a state dependent retrieval failure hypothesis.

Sub-Aversive Response Contingent Foot Shock As A Positive Reinforcer, Robert Lea Fulwiler

All Master's Theses

Forty-eight rats were divided into 8 groups; four were maintained under normal conditions and the other four under sensory deprivation and tested at o, 3, 6, and 9 days after condition institution. The response was placing the head through a hole in the operant chamber and the stimulus (0, 1.2, 4, or 12 Vac) was contingent upon the response. Analysis ot variance disclosed significant differences (p<.01) between the deprived and the non-deprived groups at days 6 and 9; and a significant interaction between deprivation condition and time of test. No differences were shown between the stimulus intensities indicating that the stimulus did not have a reinforcing effect.
