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 …

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.

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 …

Out Of Control: An Exploration Into The Dynamics Of Anorexia Nervosa And Bulimia And The Consequences For The Sufferer And Those Around Her, Shenandoah M. Cardwell

Honors Theses

A theoretical and personal exploration into the dynamics of anorexia nervosa and bulimia was conducted with reviews of literature, interviews, and personal accounts. A basic definition of the problem according to the DSM-III was stated. Discussed in detail are factors which contribute to a possible predisposition for developing an eating disorder; these include the physiological/biological, psychological, familial and societal. The effects of eating disorders on those persons around an anorexic or bulimic were explained along with a special section emphasizing the epidemic of eating disorders on college campuses. Emphasis was placed on the importance of the role of helper in …

The Deaccelerator: A Behavioral Application Of A Differentially Imposed Force Schedule To The Accelerator Pedal Of A Motor Vehicle To Control Unlawful Highway Vehicle Speed, Richard Schulman

Dissertations

The Deaccelerator is a behaviorally designed speed control device that utilizes punishment and reinforcement by way of a differentially imposed force schedule to the accelerator pedal of a motor vehicle when vehicle speed exceeds the preset speed. Specifically, increasing and decreasing accelerator pedal resistance is a negatively accelerated function of respective increases and decreases in vehicle speed as speed moves in excess of 1 mph beyond the preset speed. A lesser force schedule generates linear increases and decreases in accelerator pedal resistance as a function of respective increases and decreases in accelerator pedal depression once vehicle speed moves in excess …

Curbing Noncontractual Absences In A Mental Health Setting Through The Application Of Contingent Rewards, Craig A. Crawford

Masters Theses

In this study, the effects of contingent rewards on attendance behavior of direct care staff in a psychiatric institution were investigated. The intervention consisted of a letter of commendation and an opportunity to win a lottery for the staff exhibiting perfect attendance for a two week pay period. A multiple baseline analysis of three units failed to show significant declines in absenteeism although there were areas of significant improvement.

A Time-Management Procedure For Helping Graduate Students Accomplish Academic Tasks, Yousef Abdulwahab Abuhmaidan

Masters Theses

The purpose of this study was to investigate the effect of time-management and a task checklist on task completion, the amount of study time and students' grade point average (GPA). A package consisting of a time-management calendar and a task checklist was provided to five Jordanian students. A multiple-baseline across subjects design was used. Individual weekly meetings were conducted to assess the progress of the students on the use of the time-management calendar and task checklist. Students were asked to bring proof of accomplishments for the completed tasks. During the study the completion of tasks went from 64.6% to 92.2% …

Analysis Of The Effects Of Goal And Feedback Specificity On Subsequent Task Performance, Gregory Mark Van Dahm

Masters Theses

The effects of goal and feedback specifically on subsequent task performance were examined to text the hypothesis that specific goals and feedback facilitate performance to a greater degree than general goals and feedback (Ilgen, Fisher, & Taylor, 1979). Ten subjects, in each of the four conditions, were assigned one of two levels of goal specificity and feedback specificity and were then required to perform a simple assembly and sorting task utilizing multiple size and color fasteners. No significance was discovered between correctly assembled and sorted products of the four groups although there was a general trend in the hypothesized direction. …

Use Of A Changeover Key To Train Serial Learning In The Pigeon, Rhoda Kay Yutzy-Ryan

Masters Theses

Three pigeons were presented with a serial learning task involving a sequence of three colors: yellow, green and red. The colors appeared on a lit key one at a time in random order. The pigeons were required to peck the colors in the correct order and to use a second lit key (the changeover key) to change the color when it was incorrect. The data show that the pigeons were able to learn the task and generalize to novel arrays at a high level of accuracy. This extends the findings on serial learning with pigeons to a type of sequence …

Detection Of Deception In The Laboratory As A Function Of Motivation And Set Size, Daniel Mark Tuckett

Masters Theses

The purpose of this study was to determine the validity of the polygraph in a controlled laboratory setting. The Guilty Knowledge Test (GKT) was the procedure employed in conjunction with the galvanic skin subjects over the two trial each. Overall the polygrapher was correct 44 times, out of 80 trials. This number of detections exceeded chance (p<.001) levels. The manipulation of subject motivation with a monetary reward increased detection rates significantly (p<.05) in comparison to those offered money. With each subject being tested over two trials, there appears to be a habituation effect as indicated by a decrease in detection from trial one to trial two. The relationship fell slightly short of significance at the (p< .05) level. In general the level of the subject motivation may play a major role in the detection of subjects who attempt deceit.

Effects Of Cued Intertrial Intervals On Response Latency In Pigeons, Franklin Paul Whitley

Masters Theses

Six White Carneaux pigeons were exposed to fixed-ratio schedule components in a systematic replication of a study by Michael et al. (1981). Separation between median latencies for the two schedule components was demonstrated consistently, reproducing the general features of that research. In a subsequent manipulation, differential stimulus conditions were introduced into the intertrial intervals preceding onset of schedule components in an effort to enhance the likelihood that differential "waiting behaviors" would develop. Two subjects demonstrated a clear decrease in the magnitude of the latency splits following introduction of the cued ITI condition, while other subjects evidenced a similar but less …

The total number of tasks assigned per student for the entire study ranged from 12 to 44, with a mean of 32.6. Task completion ranged from 42% to 100%, with a mean of 68.4%. Nine of the ten students achieved a semester grade point average of 3.0 or above, although the present study did …

An Investigation Of The Effects Of An Applied Behavior Management Program On Selected Measures Of Worker Performance In A Financial Institution, Daniel A. Schroeder

Masters Theses

Twenty CRT operators from an operations department at a financial institution were used to evaluate whether a behavior management program utilizing feedback and incentives would improve their work performance on real job tasks. In accordance with predictions, results revealed that the group performed significantly better (p<.05) under the behavior management program than they did during a baseline period. Behavior management was significantly effective for most, but not all, work areas. The program also produced some unexpected, but positive, side-effects.

The Effects Of Vocal Instructions And Sequence Of Conditions On The Acquisition And Maintenance Of Behavioral Chains, Charles L. Lowe

Dissertations

Five children, ages 5 to 6 1/2 years, were trained to learn and relearn four-link behavioral chains using conditioned reinforcement. Subjects were presented with a horizontal array of 12 chips in four equal groups. During Control Learning (CL) sessions, a new sequence of responses was learned through contingency shaping. The same sequence was presented later that day during a Control Relearning (CRL) session. Instruction on correct responses was provided during Instruction Learning (IL) sessions. The same sequence was presented without instruction during an Instruction Relearning (IRL) session later that day. Thus, new behavioral chains were acquired during CL and IL …

Auditory Stimulation-Induced Analgesia In Rats: Its Irreversibility By Naloxone, Ilsun Miranda White

Masters Theses

After receiving intermittent exposure to a tone (3000 Hz, 100 db, SPL), rats were tested on a hot plate for analgesia. Rats that received tone alone showed a higher average paw-lick latency than rats that received either naloxone or saline alone. This result indicates that the auditory stimulus used in this study can be considered a neurogenic stressor and may be added to the list of various noxious stimuli that prouces analgesic effects. Naloxone given to tone-treated subjects produced mean paw-lick latencies were comparable to control group latencies for the first two treatment sessions and to tone group latencies for …

The Effects Of Instructions And Cue Controlled Relaxation Training On Cardiovascular Reactivity To Social Stressors, Patricia A. Fettes

Masters Theses

Cue controlled relaxation (CCR) training was compared to simple instructions to relax and control blood pressure on the basis of their effects on cardiovascular reactivity to role played social stressors. The CCR intervention consisted of training subjects to say a cue word ("calm") that had been previously paired with muscular relaxation responses, during presentation of stressors. The instructions intervention was associated with significant reductions in blood pressure reactivity, regardless of whether this condition preceded or followed the CCR condition. Factors that may relate to the relative ineffectiveness of CCR are discussed, as well as those that may have been responsible …

An Analysis Of Potential Adjunctive Behavior In Two Developmentally Disabled Subjects, Nancy K. Brhely

Masters Theses

Past research on adjunctive behavior in humans has generally not employed methods which are comparable to those included in studies of adjunctive behavior in nonhumans. Consequently, the results of these studies of adjunctive behavior in nonhumans. Consequently, the results of these studies are often difficult to interpret. The present study examined locomotor movement and salient self-stimulatory behaviors in two developmentally disabled students exposed to four fixed-interval (FI) schedules of food delivery (FI 16-, 60-, 120-, and 240-sec). Results of this study were analyzed according to whether the seven defining characteristics of the prototype of adjunctive behavior, polydipsia, were present. Locomotor …

Increasing Key “Sales Related” Behaviors Through The Use Of A Self-Monitoring Checklist, Susan M. O'Brien

Masters Theses

The present study investigated the effects of self-monitoring alone to increase targeted key sales related behaviors with an outside sales representative. The data collected over a five-month period of time revealed a temporary increase in the overall percent of targeted behaviors performed on each sales call when self-monitoring was implemented. Performance dropped to baseline levels near the end of the first treatment phase prior to the reversal phase. The data were inconsistent across behaviors as to whether implementing self-monitoring caused them to change in the desired direction or not. Additional measures which were not directly influenced by the self-monitoring technique …

The Use Of Repeated Acquisition As A Technique For Establishing A Behavioral Baseline With Victims Of Alzheimer's Disease, Michelle D. Stone

Masters Theses

Three subjects suspected as Alzheimer's Disease (AD) victims were trained on a behavioral chain of three sets of three poker chips, each set differing in color and position, to investigate subtle changes in learning and performance behaviors over time. For each session the subjects learned a new three-response sequence with a marked poker chip serving as the correct response for each set. A within-session learning curve resulted for all three subjects with the errors in the learning trial (LT) exceeding the errors for the performance trials (PT1 and PT2). Only Subject III demonstrated a stable pattern of learning, with the …

Behavioral Toxicology Of A Glucocorticoid: Analysis Of Selected Behavioral And Physiological Effects Of Repeated Prednisolone Treatment, Robert G. Sewell

Dissertations

Glucocorticoids are used medicinally for numerous chronic ailments. While dramatically effective, glucocorticoid treatment is replete with psychiatric complications. The behavioral toxicology of glucocorticoids, however, remains relatively unexplored. Therefore, 13 laboratory studies were performed to analyze the influence of prednisolone, a representative glucocorticoid, upon varied behavioral and physiological endpoints in rats. Experiments 1-3 showed prednisolone to produce marked hypodipsia, body weight loss, selective adrenal gland atrophy, hyperactivity, hyperalgesia, altered grasping responses, hyperglycemia, enhanced predation, and conditioned taste aversion. Most of these findings were directly dependent upon dose, and where explored, number of treatments. The remaining ten studies examined both acute and …

Reinforcement Increases The Strength Of An Elicited Response, Michael D. Peters

Dissertations

A response initially produced by noncontigent fixed-time delivery of brief electric shock was strengthened by reinforcement. Following the fixed-time shock baseline condition, response contingent shock absence (avoidance) was programmed for the lower probability of two response options for one group of squirrel monkeys. For the other group the interposed history was variable-interval food reinforcement. When responding was reliably maintained reinforcement was discontinued and a return made to fixed-time shock conditions as programmed prior to reinforcement. Upon a return to original conditions, rates were substantially elevated over baseline with the elevation sustained for many sessions. The avoidance group showed the most …

Tamoxifen Effects Upon Body Weight, Water Intake, And Several Behaviors, And Tamoxifen’S Unconditioned Stimulus Properties In The Conditioned Taste Aversion Paradigm, Steven J. Anderson

Masters Theses

The antiestrogen tamoxifen citrate (Stuart Pharmaceuticals) is indicated for treatment of breast cancer. Tamoxifen (TMX) is frequently employed because of demonstrated effectiveness in tumor reduction and a low incidence of debilitating side effects compared to similar agents. Even though side effects are uncommon with use of TMX, medical and behavioral sequalae have been noted. The present , . study investigated several behaviors in female rats administered TMX in two separate studies. In the first investigation, the effects of 25 daily treatments of TMX upon body weight, water intake, and several behaviors were assayed. In the second study, aversion to a …

Rule-Governed Behavior In Preschool Children, Cassandra Ann Braam

Masters Theses

The control exerted by different types of rules on the behavior of preschool children was determined. Using a variation of a multielement design, four topographically similar rules were presented to seven four-year-old children. The rules varied in the deadlines and delay of consequences (rewards) specified. The results showed that: (a) requests or mands specifying only response requirements generally exerted poor control; (b) rules specifying an immediate deadline and an immediate reward exerted strong control; (c) rules specifying deadlines and a one-week delay of the reward exerted good control; and (d) rules specifying no deadlines for completion and a one-week delay …

A Comparison Of Similar Versus Dissimilar Competing Response Practice In The Treatment Of Muscle Tics, Ellen L. Sharenow

Masters Theses

Miltenberger, Fuqua, and McKinley (1985) reported that the competing response component of the habit reversal treatment package (Azrin & Nunn, 1973) when presented alone was as effective as the entire habit reversal procedure in suppressing muscle tics. In a related study, Miltenberger and Fuqua (1 9 8 5 , in press) reported that the performance of the competing response contingent on the occurrence of a variety of nervous habits resulted in greater response suppression than the non-contingent performance of the competing response. In an effort to determine whether the topography of the competing response was important to the reported effects, …

Instructional Control Of Leniency In Self-Appraisals, Maria Barnum Nelson

Masters Theses

Self- and supervisor ratings were obtained on four classifications of non-teaching public school employees across two instructional conditions. Self-ratings showed more leniency in the condition where employees were instructed not to meet with the supervisor to discuss the ratings; self-ratings showed less leniency in the condition where employees were instructed to meet with the supervisor to discuss the ratings. Despite foreknowledge of the research question and instructional conditions, supervisors showed a tendency to rate employees differentially according to the instructional conditions. The results of the analyses demonstrate the potency of instructional control on rating behavior by employees and supervisors. Questions …

The Effects Of Reward And Reinforcement On Intrinsic Interest, Alyce Muzette Dickinson

Dissertations

Under certain circumstances, rewarding individuals for performing a task that they enjoy may decrease their subsequent interest in that activity when rewards are no longer available. Decreased task interest is not, however, an inevitable outcome of reward and the subsequent termination of reward. This study investigated one variable that may influence whether task interest will increase or decrease following reward termination: the degree to which the reward is reinforcing. The study also examined how long post-reward performance changes persisted when they occurred.

A multiple-trial, within-subject comparison design was employed in which three reward phases were alternated with post-reward phases. Two …

The Use Of An Incentive System To Increase Worker Performance In A Financial Setting, Steven S. Armstrong

Dissertations

The use of merchandise as a consequence in a performance based incentive system was assessed in a financial setting. Points were earned by each subject based on individual daily performance. These points were collected by each subject and used toward the purchase of merchandise. A multiple baseline across two groups of bank tellers showed substantial increases in worker behavior after the onset of contingent points. Differences between groups existed and an analysis is provided. Follow-up data revealed sustained performance and a cost-benefit analysis demonstrated substantial savings.

The Effect Of Medicaid Billing On Service To Developmentally Disabled Adults, Kambiz Alavi

Dissertations

This study provides a detailed analysis of the daily service delivery records before and after the introduction of a Medicaid Billing Form at a day-activity center for developmentally disabled adults. The form required therapists to record daily service delivery (in 15-minute units) to Medicaid eligible clients. There were 38 clients, 23 Medicaid and 15 non-Medicaid, and four therapists. The data showed, for three of the four therapists, a clear and large increase in reported service delivery to Medicaid clients and a smaller increase to non-Medicaid clients. Six months after the introduction of the Medicaid Billing Form the therapists were required …

The Feature-Value Effect In Children; An Attempt To Replicate And Further Experimentation, Kathleen Wright

Dissertations

In the "feature-value effect" faster acquisition occurs when a distinguishing feature is placed on the correct stimulus (S+) during discrimination training than when the distinguishing feature is placed on the incorrect stimulus (S-). The former is a "feature positive" discrimination task, whereas the latter is a "feature negative" discrimination task. The feature-value effect only occurs when the discrimination involves stimuli that are identical except for one distinguishing feature. The effect has been obtained in a number of nonhuman species as well as in children and adult humans. Experiments 1 and 2 failed to replicate the findings of previous experiments with …
