The Acute Effects Of Cocaine In Pigeons Performing Under A Progressive-Ratio Schedule, Claudia Ann Jones

Masters Theses

Although the progressive-ratio (PR) schedule has been used frequently to quantify the reinforcing effectiveness of self-administered drugs, it has seldom been used to examine the effects of drugs on food-maintained behavior and has never been used to evaluate the effects of cocaine on such behavior. In the present study, the effects of acute administrations of cocaine were evaluated in pigeons responding under a PR schedule of food delivery. Overall, cocaine produced a dose-dependent effect on food-maintained behavior. In general, acute administrations of cocaine at 0.56 to 3.2 mg/kg increased breaking points, whereas doses above 5.6 mg/kg decreased breaking points. Low …

Spanish Translation And Validation Of The Daily Stress Inventory, And A Comparison Of The Level Of Stress Experienced By Three Culturally Distinct Hispanic Groups, Senez Rodriguez-Charbonier

Dissertations

High levels of stress in the general population have been found to correlate both with psychological and physical illness. The fast growing Hispanic population in the U.S. is exposed to increased levels of stress associated with a number of situations (e.g., language barriers, and socioeconomic status). There are, however, no validated stress measures applicable to the Hispanic community as a whole.

The purpose of this study was twofold: First, to translate into Spanish the Daily Stress Inventory (DSI) (Brantley & Jones, 1989) and to validate the translation by conducting a correlation study between the the Spanish and the English versions. …

Failure Of Methamphetamine Withdrawal To Produce Behavioral Disruptions In Pigeons, William F. Potter

Masters Theses

Methamphetamine, a widely used recreational drug, is not known to produce physiological dependence. Few studies to date have examined whether behavioral dependence occurs upon sudden withdrawal from methamphetamine. In this study, pigeons (n=4) were trained to respond under a multiple FR 25 IRT > 6-s schedule of reinforcement, allowing for examination of drug effects upon a relatively high rate of responding (FR) and a relatively low rate of responding (IRT > t). Acute adminstrations of methamphetamine showed rate-dependent effects at low doses, while higher doses decreased responding under both schedules. Tolerance was demonstrated for all subjects except one at the highest dose …

The Effects Of Differing Response Force Requirements On Response Rate And Post-Reinforcement Pause, Kenneth Lee Ailing

Dissertations

The present study consisted of three experiments in which rats were exposed to two-component multiple schedules of reinforcement. In the first experiment, fifteen responses were required to produce reinforcement in both components of the multiple schedule. In one component 25 g of downward force was always required to operate the response lever. In the other, the force required varied from 25 g to 200 g across conditions. In the second experiment, fifteen responses were required to produce reinforcement in both components of the multiple schedule. In one component 25 g of downward force was always required to operate the response …

The Vocational Interests Of Prisoners: A Preliminary Validation Study Of The Lustig Color Vector Test, Hanoch Livneh, Robert E. Pullo, Paul Lustig

Counselor Education Faculty Publications and Presentations

The purpose of this study was to provide empirical evidence for the validity of the Lustig Color Vector Test (LCVT) as a vocational interest measure. The LCVT, a nonverbal instrument, is a schematic attempt to represent the Vector Theory of Behavior which describes human behavior in terms of motion and the laws of physics. A sample of 92 participants was chosen to represent the literate male population of incarcerated offenders in the Wisconsin state prison system.-Participants were administered the LCVT as well as Holland's Vocational Preference Inventory (VPI) and a demographic questionnaire. The results offered tentative support to the notion …

An Arbitrary Matching Training Supplement To The Avc Discrimination Test, Charles P. Butler

Masters Theses

Kerr, Meyerson and Flora (1977) devised a series of small learning tasks that could be used to assess developmentally disabled individuals on the typical tasks to be performed in a school setting or sheltered workshop and required only very simple equipment. Davine (1990) suggested that there may be transitional skills between AVC levels IV and V not found by Kerr et al. Davine looked at four experimental steps designed to test this notion. The results of this study were inconclusive. Wilson (1991) tested the same notion by devising a series of non identity matching tasks which were generally found to …

Lesions Of The Perirhinal Cortex But Not Of The Frontal, Medial Prefrontal, Visual, Or Insular Cortex Block Fear-Potentiated Startle Using A Visual Conditioned Stimulus, Jeffrey B. Rosen, Janice M. Hitchcock, Mindy Miserendino, William A. Falls, Serge Campeau, Michael Davis

Psychology Faculty Publications

The present study is part of an ongoing series of experiments aimed at delineation of the neural pathways that mediate fear-potentiated startle, a model of conditioned fear in which the acoustic startle reflex is enhanced when elicited in the presence of a light previously paired with shock. A number of cortical areas that might be involved in relaying information about the visual conditioned stimulus (the light) in fear-potentiated startle were investigated. One hundred thirty-five rats were given 10 light-shock pairings on each of 2 consecutive days, and l-2 d later electrolytic or aspiration lesions in various cortical areas were performed. …

The Effect Of Associative Distance On The Formation Of Transitive Relations, Robert G. Brown Jr.

Dissertations

Three children, aged eight to eleven years, were taught a series of conditional discriminations using two classes of 26 abstract visual stimuli. The conditional relations were ordered such that the correct comparison stimuli of one relation served as the sample stimuli for the next relation. This allowed for the formation of a series of derived relations (both transitive and equivalence) that differed in terms of the number of intervening nodes. At regular intervals, the subjects' performances on the different transitive relations were tested using unreinforced probe trials.

All three subjects made virtually no errors on transitive relations containing up to …

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 …

Effects Of Feedback Type And Signal Probability On Quality Inspection Accuracy, Matthew A. Mason

Dissertations

A computer simulation was developed to examine the effects of feedback type (immediate, delayed, or none) and signal probability (p = 0.05 or 0.12) on the accuracy of identifying signals (missing components), inspection response rate, and response sensitivity (d'). Subjects were randomly assigned to one of six experimental groups: (1) immediate feedback with a signal probability of 0.05 (1/0.05), (2) delayed feedback with a signal probability of 0.05 (D/0.05), (3) no feedback with a signal probability of 0.05 (N/0.05), (4) immediate feedback with a signal probability of 0.12 (1/0.12), (5) delayed feedback with a signal probability of …

Appeal And Vulnerability Patterns In Girl Victims Of Incest, Ruth Mausert-Mooney

Dissertations

This study compared certain personal characteristics and behaviors of sexually abused girls with those of matched controls. Experimental subjects were 49 girls, aged 6 to 16 years, who had been sexually abused by an older male family member. Fifty girls who had not experienced sexual abuse served as the comparison group, matched on the basis of age, race and socioeconomic status.

Demographic and psychological measures were completed by each research participant and her mother. Videotapes were made of an initial session in which each child met an unknown male tester.

This study hypothesized and affirmed that sexually abused girls appeared …

Job Aids, Feedback, And The Teaching Of Verbal-Reasoning, Angela Williams Campbell

Dissertations

The purpose of this study was twofold: (1) to test the effects of a job aid and feedback on learning to solve directional verbal-reasoning problems, and (2) to examine whether students’ skills transferred to similar problems following the removal of both the job aid and feedback. Some previous researchers who studied problem solving utilized the think-aloud technique and used solutions generated by expert problem solvers. The think-aloud technique, although perhaps a good one, is not practical in the classroom. In the main study, a job aid was incorporated within the problem so students would be able to use guidance toward …

A Comparison Of Blood Volume Pulse And False Biofeedback In The Treatment Of Migraine, Paul Greilick

Dissertations

The efficacy of temporal artery blood volume pulse (BVP) biofeedback in the treatment of migraine was investigated. After four pre-treatment baseline psycho-physiological monitoring sessions, 8 migrainuers were randomly assigned to undergo 12 sessions of either BVP biofeedback or a placebo procedure (false feedback). Both treatments resulted in clinically significant and statistically equivalent reductions in headache activity and medication intake. Subjects exhibited substantial within-session decreases in BVP amplitude during pre-treatment baseline sessions and during false feedback, and the introduction of BVP biofeedback failed to increase the magnitude or the rate of BVP amplitude reductions. All subjects failed to show evidence of …

A Comparison Of Four Methods To Teach Complex Verbal Concepts Using A Computer-Assisted Instruction Program, John Byron Connors

Dissertations

This study compared four instructional programs which taught terminology in behavioral psychology using computer-assisted instruction (CAD with college students. The independent variable was the type of instruction presented by one of four CAI programs: (a) Rules Only, (b) Rules Plus Positive Examples, (c) Rules Plus Negative Examples, and (d) Rules Plus Positive and Negative Examples. The dependent variables were the: (a) pretest scores, (b) posttest scores, (c) 1-week delayed posttest scores, and (d) preference questionnaire scores. Using the pretest as a covariate, results approached significance (p=.07) on posttest scores only for the Rules Only and Rules Plus Positive Examples over …

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 …

Letter Recognition By Mentally Retarded Adults: Improving Performance Through Differential Outcomes, Paul R. Malanga

Masters Theses

Four mentally retarded adults were taught to recognize (i.e., discriminate) finger spelling letters when presented as members of unchanging pairs (e.g., A and E, G and H). Correct responses were followed by food or verbal praise. On average, terminal accuracy was significantly greater when a correct response to a given letter was consistently followed by a particular outcome (e.g., food followed correct responses to A and praise followed correct responses to E) than when nondifferential outcomes were arranged (e.g., food followed 50% of all correct responses and praise followed the remaining 50%, regardless of whether the responses were to A …

Extinction Of Fear-Potentiated Startle: Blockade By Infusion Of An Nmda Antagonist Into The Amygdala, Michael Davis, William A. Falls, Mindy Miserendino

Psychology Faculty Publications

Data derived from in vitro preparations indicate that NMDA receptors play a critical role in synaptic plasticity in the CNS. More recently, in vivo pharmacological manipulations have suggested that an NMDA-dependent process may be involved in specific forms of behavioral plasticity. All of the work thus far has focused on the possible role of NMDA receptors in the acquisition of responses. However, there are many examples in the behavioral literature of learning-induced changes that involve the reduction or elimination of a previously acquired response. Experimental extinction is a primary example of the elimination of a learned response. Experimental extinction is …

Factor Analysis Of The Personal Profile System, Thomas G. Henkel, James Noel Wilmoth

Publications

Principal components extraction with orthogonal and oblique rotations tested construct validity for the Personal Profile System. MOST-LIKE endorsements of 96 behavioral descriptors were coded with 4, LEAST-LIKE with 1, and unendorsed with 2.5. Descriptor data from 1,045 senior noncommissioned Air Force officers were normalized. Four factors accounted for 85% of total variance, with 19 descriptors loading significantly on two factors and the remaining 77 on just one factor. The measure of sampling adequacy for every descriptor exceeded .94. One factor for the varimax-rotated (best) analysis was bi-scalar, loading on Steadiness and Compliance descriptors; a second resembled Influencing, a third loaded …

Sequences Of Fixed-Ratio Schedules Of Reinforcement: The Effect Of Ratio Size In The Second And Third Fixed-Ratio On Pigeons' Choice, Susan Goeters

Dissertations

The present study used a discrete-trials procedure to examine choice in pigeons presented with various three-component sequences of fixed-ratio schedules of reinforcement. An experimenter-controlled stimulus was correlated with each sequence and pigeons were presented with a specified number of forced-exposure and choice trials. Three phases were implemented in an effort to investigate the conditions under which fixed-ratios other than the first in a sequence of three affect choice. In Phase 1, pigeons were given a choice between a fixed-ratio X fixed-ratio 1 fixed-ratio 25 and a fixed-ratio X fixed-ratio 25 fixed-ratio 1 sequence of food delivery. Across conditions, X was …

Effects Of Music As A Conditioned Stimulus And Progressive Muscle Relaxation In Reducing Anxiety, Marie Elaine Clarkson

Masters Theses

The primary purpose of this study was to determine whether music could become a conditioned stimulus for lowered muscle tension and/or reduced anxiety.

There were three groups: (1) the PMR group receiving PMR alone, (2) the MUS group receiving music alone, and (3) the PMRM group receiving PMR followed by music. After four training sessions, a posttest was conducted in which all of the groups were given five minutes to relax. The PMR group had silence, the MUS group had music and the PMRM group had music which had previously been heard after relaxation training. Tension and anxiety reduction were …

Nonidentity Matching Training As A Supplement To The Audio-Visual Combination Test, Melissa Wilson

Masters Theses

The Audio-Visual Combination Test is an assessment tool developed by Kerr, Meyerson, and Flora (1977), and used by those working with developmentally disabled persons to assess learning-to-learn skills. The test measures motor, visual, and auditory discrimination learning.

The experimenter attempted to determine if there were an important step-visual nonidentity discrimination-between AVC subtests 4 and 5/6 of the test. Twelve developmentally disabled adults were tested with three different sets of tasks interposed between a revised subtest 4 and 5/6. Results showed that most subjects had greater difficulty with the visual nonidentity discrimination than with the auditory/visual discrimination, subtest 5/6. The results …

The Effects Of Mephenytoin On Schedule-Controlled Responding In The Pigeon, Victoria Mary Pellettiere

Masters Theses

Acute and chronic effects of mephenytoin (30 - 360 mg/kg) were examined in pigeons responding under a multiple fixed-ratio 50 fixed-interval 90-sec schedule of food delivery. The highest dose administered acutely (240 mg/kg) produced substantial reductions in rate of responding under both components of the multiple schedule; the effects of other doses were small and inconsistent. Tolerance appeared to develop to the rate-decreasing effects of mephenytoin following chronic exposure to the drag.

The Effects Of A Conditioned Establishing Operation On Performance Of A Two-Component Chain, Kenneth Lee Alling

Masters Theses

Subjects were exposed to a discrete-trial procedure in which reinforcement following the completion of a two-component response chain was dependent upon the presence or absence of the houselight. The procedure used closely resembles the hypothetical procedure suggested by Michael (1982) for developing control by a conditioned establishing operation. All subjects came to respond differentially in the presence and absence of the houselight. However, removal of the supposed conditioned reinforcer following completion of the first component of the response chain had little effect on control by the houselight, casting some doubt on Michael's (1982) theoretical analysis.

Effects Of Phenobarbital In Combination With Phenytoin Or Valproic Acid On The Delayed-Matching-To-Sample Performance Of Pigeons, Catherine Ann Karas

Masters Theses

The present study examined the effects of phenobarbital (S, 10,20, and 40 mg/kg), phenytoin (2.5, 5, 7.5, and 15 mg/kg), and valproic acid (40, 60, 80, and 120 mg/kg), and those of phenobarbital (10 and 20 mg/kg) in combination with phenytoin (2.5,5, and 7.5 mg/kg) or valproic acid (40, 60, and 80 mg/kg), on the delayed-matching-to-sample performance of pigeons. In general, high doses of each individual drug reduced accuracy. Drug combinations also reduced accuracy relative to control values. Reductions in accuracy produced by drug combinations were very similar in magnitude to those predicted by a response-addition model of drug interaction.

A Computer Simulation Of Braitenberg Vehicles, Eric B. Werkowitz

Theses and Dissertations

In his treatise, Vehicles: Experiments in Synthetic Psychology, Valentino Braitenberg used simple, autonomous vehicle designs to illustrate the principles behind animal nervous system organization and operation. The goal of this effort was to produce a computer program to allow a researcher to experiment with these concepts and to analyze their performance using methods employed by experimental psychologists. The resulting program allows the user to design vehicles that respond to changes in their environments and that have the ability to adapt their behavior, using a learning algorithm developed by Teuvo Kohonen. The vehicle designer is free to select sensor attributes, …

Factoring The Personal Profile System For Construct Validity: Three Analyses Under Different Standardization Assumptions, Thomas G. Henkel, James Noel Wilmoth

Publications

Three types of data were factor analyzed using principal components extractions with orthogonal and oblique rotations to test publisher claims for construct validity of the Personal Profile System (PPS). Behavioral descriptor data from 1,045 senior non-commissioned Air Force officers were factored as raw data, mean corrected data, and standardized z-scores (correlations). The most efficacious solution was produced with standardized z-scores generating four factors accounting for 86% of the total variance. The measure of sampling adequacy for every descriptor exceeded 0.922. The first factor was general with approximately equal loadings on each of the dominance, influencing, steadiness, and compliance dimensions. The …

The Effects Of Relapse Prevention Training On Exercise Adherence, Sandra Beaty

Dissertations

Behavioral techniques have proven effective in the acquisition and maintenance of new behaviors. However, health related behaviors, such as exercise, pose a special problem for the field of behavior change in that they require long-term lifestyle changes. This study assessed the effectiveness of relapse prevention training on exercise adherence within the framework of a formal exercise program. There were 20 subjects in the experimental group and 20 subjects in the control group. Both groups met for three, one-hour sessions weekly for eight consecutive weeks. Exercise class attendance was recorded by the instructor. In addition, the Physical Activity Index (PAI, n.d., …

Generalization Of Promise-Do Correspondence Training With Respect To The Individual To Whom The Promise Is Made, Robert J. Latka

Masters Theses

This study used 3 subjects of normal (non-impaired) intelligence, 1 female and 2 males, between the ages of 10 and 13 years to study generalization of promise-do correspondence training effects. In a replicated AE design, contingent monetary reinforcers were used to establish promise-do correspondence in playing nonpreferred computer games. This study demonstrated that the effects of correspondence training procedures could be generalized to an alternative listener or individual to whom the promise was made. Generalization was less evident when there was no listener present. This study also provided some evidence that effects of promise-do correspondence training may not generalize to …

The Effects Of A Reinforcer On Behavior Maintained By A Second External Reinforcer, Jeanne Marie Lamere

Masters Theses

A number of studies has shown that providing extrinsic rewards for performing an "intrinsically interesting" task decreases an individual's subsequent interest in that task when the rewards are no longer available (e.g., Deci, 1971, 1972; Lepper, Greene, & Nisbett, 1973). Based on these results, many have argued that extrinsic rewards decrease an individual's "intrinsic motivation." A fundamental premise of this argument is that "extrinsic" and "intrinsic motivation" are functionally different, a distinction that is not supported by a behavioral analysis. This study examined whether similar subsequent decrements in task performance would be observed when a behavior is maintained by one …

A Comparison Of The Effects Of A Linear And An Exponential Performance-Pay Function On Work Productivity, Shezeen Oah

Dissertations

This study examined how work productivity was affected by the way in which individual monetary incentives were related to performance. Two types of relationships, or performance-pay functions, were compared: a linear function in which a specific per piece incentive was provided for each piece completed in excess of a performance standard and an exponential function in which the amount of the per piece incentive accelerated as productivity increased. Forty college subjects were randomly assigned to one of the two pay conditions. Each subject participated in 15 forty-five minute sessions. Subjects performed a computerized work task that simulated the job of …
