The Generalizability Of Learned Helplessness, Ian J. Grabenhorst

All Master's Theses

While it has been experimentally demonstrated that "learned helplessness" can be conditioned in a number of species, the subjects commonly employed have been dogs. This paper presents an attempt to investigate "learned helplessness" in rats (a variant of the Long-Evans strain), and examine the question of its generalizability from shock as an aversive stimulus to noise. It also explores the possible generality of "helplessness" to exploratory behavior in an open field. The results demonstrated that the Ss were susceptible to "helplessness" conditioning across shock conditions; however, "helplessness" did not generalize across shock to noise conditions. The present study also showed …

The Relationship Of Verbal And Symbolic Mediation To Induced Meaning, Dennis G. Groome

All Master's Theses

Four experimental groups were presented nine induced-meaning training trials with 20 CVC stimuli and either abstract or concrete noun, picture alone, or picture plus noun responses. Two control groups received no training trials. Two experimental groups were required to learn associations and the other two simply viewed S-R pairings. Half the groups in each condition generated images and the other half generated word associates to 12 nouns and 20 CVCs. No evidence of induced meaning or of active versus passive learning differences was found. Suggestions for more effective experimental procedures are made.

Reversal Shift Performance By Young Children As A Function Of Stimulus Presentation Mode, Beverly Faye Miller

All Master's Theses

The present study required three groups of Ss (gifted preschoolers, average preschoolers, and first graders) to solve a reversal shift (R). It was hypothesized that greater verbal competency among any of the three groups would lead to superior performance on the R shift. The results indicated that first graders performed significantly better than the average preschool children on the R shift. Also the performance of the first graders was reliably superior to the gifted children on one postshift phase analysis; on the remaining postshift comparisons a visual trend in the same direction was observed. Three separate stimulus presentation modes were …

Locus Of Control And Achievement Incentive In A Risk Taking Situation, Frederick Gordon Carr

All Master's Theses

High and low achievement incentive conditions on the risk taking behavior of subjects identified on the Rotter Internal-External Control Scale as having orientations of internal or external control were examined.

The study involved tossing balls at a target in which subjects chose throwing distances. Successes from greater distances were worth more points. A five dollar incentive was offered to half the subjects.

Males took higher risks than females but no other significant differences were found.

The Effects Of Pattern Of Extraneous Auditory Stimuli And Sex On Vigilance Performance, Paul G. Fisher

All Master's Theses

Eighty introductory-level psychology student volunteers performed a sweep-clock perceptual vigilance task. Each subject was exposed to one of four noise conditions: 65-dB constant noise, 100-dB constant noise, 100-dB regularly-intermittent noise and 100-dB variable intermittent noise. No overall effects of pattern of presentation schedule of noise on performance were found. Time-related changes in three measures, correct detections, reaction times, and incorrect detections plus sex differences in reaction times, were found. In the regularly-intermittent condition females showed a greater time-related decrement in correct detections than males and made fewer incorrect detections. With intermittent background stimulation the time-related change in incorrect detection rates …

Spatial Orientation Of Children In Dyads With Female Adults, Susan Menig Karstetter

All Master's Theses

Subjects were requested to enter the experimental setting, choose a chair, and sit while speaking to an adult female who listened to the child for two minutes. The distance and angle of seating were measured and studied with regard to the age, sex, grade level, height, handedness, academic achievement, size of chair used, and the listener.

The results indicated that seating distance was influenced by the sex, age and height of the subject and size of chair chosen. The angle of seating chosen was influenced by the sex and height of the subject and the size of chair chosen. It …

The Role Of Memory In Rule Learning Problems, Alan S. Kertes

All Master's Theses

Thirty-six college subjects who had taken a memory test from the Wechsler series were chosen from an introductory psychology class and divided into three memory levels (high, medium, and low). Twelve subjects from each of the memory groups were required to categorized geometrical stimulus patterns into positive and negative instances according to an unknown conceptual rule that prescribed a relationship between two known attributes. Each subject was assigned to one of three postfeedback delay intervals of 1.5, 20, or 30 seconds. Performance among the three memory levels was not statistically different even though differences from best to worst were apparent …

The Role Of Postfeedback Intervals In Rule Learning Problems, Donald E. Lloyd

All Master's Theses

Subjects classified bidimensional stimulus patterns of variable colors and shapes into positive or negative instances of the concept, according to one of three conceptual rules (Disjunctive, Conditional, or Biconditional). Four postfeedback intertrial intervals were used: 1.5, 5, 20, or 30 seconds. Performance on the Dj rule was significantly higher than either the Cd or Bd rule and there was no reliable difference between the later two rules. The postfeedback delay was not a reliable source of variance among all rules, but did yield significant differences within the Bd rule. Inconsistent performance trends in the Cd and Bd rules as the …

Low Intensity Footshock Examined As A Possible Reinforcer For Sensory Deprived Rats, Ron J. Madesh

All Master's Theses

Two experiments were performed, first to test the footshock threshold for rats reared in the Central Washington State College rat colony and second to test for reinforcing effects of low level footshock for sensory deprived subjects. The threshold study consisted of an active avoidance situation with a low intensity footshock as the conditioned stimulus. Using the method of limits, thresholds were established (using 200k. ohms resistance in series) at 19.10 Vac and 22.60 Vac for sensory deprived and control subjects respectively. The second study tested for preference for footshock versus no footshock in an open shuttle box situation. No significant …

The Effects Of Extraneous Stimulation And Activity On Performance In A Recognition-Memory Task, Richard Armstrong

All Master's Theses

Reaction times of 36 subjects in a recognition-memory task were used to evaluate the effects of extraneous stimulation and activity upon memory processes. No significant effect of noise on RT was suggested. A linear increase in reaction time as a function of memory load was found in all noise conditions. When the recognition-memory task was accompanied by a simultaneous shadowing task, a significant difference in the positive and negative reaction times was suggested.

The Effects Of Experimental Manipulation Of Status On Signature Size, Karen Jensen Gillespie

All Master's Theses

This paper presents an attempt to change the size of a person's signature by changing his perceived status within the experimental situation.

Eight-four subjects were divided into four equal groups. Each group received two treatments, one of which was a status treatment, the other a success-failure manipulation. The results showed a significant difference in signature size between high and low status treatment groups. A significant variation was also noted between females in the success manipulation group and females in the failure manipulation group. The direction of this variation was opposite to predictions.

Recommendations included addition of a control group, presentation …

The Effect Of Environmental Enrichment On Delayed Alternation, Passive Avoidance And Exploration Behavior, David L. Knobel

All Master's Theses

Long Evans Hooded rats were reared in either perceptually complex (EC) or simple (IC) environments. As adults, exploration, delated alternation and passive avoidance task performance was investigated. The exploration level of the EC and IC reared groups was identical on Day 1, but on subsequent days the IC rats on delayed alternation and passive avoidance tasks was not found, but the alternation response was acquired with significantly fewer trials by EC rats.

Food Intake In Rats As A Function Of Shock-Avoiding Eating Behavior, Kathleen A. Carlton

All Master's Theses

Consumption of a liquid nutrient by rats under several different circumstances was studied. A restraining apparatus and tailshock were used to train one group to lick a drinkometer tube, creating a forced drinking situation. It was hypothesized that rats in this group would consume significantly more than Ss in the other three groups during a testing phase. The hypothesis was disconfirmed by statistical analysis, though there appeared to be a tendency for avoidance training to produce effective results.

The Effect Of Stimulus Complexity On Retrieval Of Information From Memory, George M. Delegans

All Master's Theses

Eighteen subjects performed an item-recognition task, involving memorized lists of 1, 2, and 3 nonsense forms, at one of 2 levels of stimulus complexity. Analyses of reaction times as a function of set size and serial position suggested that (a) when the memorized list consisted of simple figures, subjects engaged in a serial exhaustive search, and (b) when the memorized items were complex, the assumption of a simple serial search was untenable.

The Fear Conditioning Cues Necessary For The Reinstatement Of Memory After Retrograde Amnesia Induced By Ecs Ina One Trial Fear Conditioning Paradigm, Thomas Martin Hopfer

All Master's Theses

Rats were trained in a one trial fear conditioning paradigm (tone paired with footshock) after they had been trained to drink from a water tube. Fear conditioned animals given ECS (TFS/ECS) showed fear responses, indistinguishable from similarly treated animals given no ECS (TFS/ECS), when administered post-treatment fear conditioning cues 96 and 97 hours after fear conditioning day and tested 120 hours after conditioning. In addition, amnesia was shown at the 120 hour test in the TFS/ECS animals that received no post-treatment fear conditioning cues compared to similarly treated TFS/NECS animals. Further, animals that received the same experimental treatments as the …

Effects Of Reinforcement Schedules On The Eating Behavior Of Hooded Rats, Wayne T. Pratt

All Master's Theses

While the eating behavior of organisms has been the subject of considerable research, the methods commonly employed to disrupt eating behavior also result in irreparable damage to the central nervous system. This paper presents an attempt to evaluate some effects of reinforcement schedules on the eating behavior of hooded rats when external motivating factors were introduced.

The results indicated that stress tended to inhibit food intake to a significant degree.

Problems associated with this method of creating obesity were discussed and suggestions offered for further research.

Transfer Of Active Avoidance Response Tendency By Brain Extract, Marlene Sanders

All Master's Theses

Interanimal memory transfer was tested using an active avoidance task in which donor rats were trained to jump onto a platform to avoid a footshock. One control group was allowed to freely explore the experimental chamber and a second control group received footshock in the chamber but without the opportunity to avoid.

Results indicated that recipients of trained donor extract learned the task in significantly fewer trials than recipients of control donor extract. Suggestions for further research and modifications of this study were discussed.

The Effects Of Electroconvulsive Shock Following Different Noncontingent Foot Shock Durations On A Conditioned Emotional Response, Carol Knobel

All Master's Theses

Varied lengths of noncontingent foot shock (NCFS) followed by an ECS or NO ECS were presented 24 hours after fear conditioning to investigate the state dependency hypothesis. The hypothesis that the NCFS would interact with ECS to produce a transient attenuation of fear conditioning was not supported. Results were discussed in terms of the possibility that the state dependency hypothesis applies only to certain levels of brain excitation when NCFS and ECS are used to induce brain state changes.

Food Choice Preferences And Delay Of Reward In Obese And Normal Weight Children, Mitzi M. Rochester

All Master's Theses

Thirty-seven obese and thirty-six normal weight children, ages eight to eleven, of both sexes were tested to determine if the cue prominence theory of obesity would be supported early in life. Ss chose a candy bar as a reward for a task from one of three bowls, containing either large bars in plain brown wrappers, small bars in brightly colored wrappers, or small bars in plain brown wrappers. Obese and normals did not differ in their choices: 67% of the obese and 80% of the non-obese children chose the large candy bars in plain wrappers. However, obese Ss chose significantly …

Self Persuasion As A Function Of True And False Confession, Barry A. Stevens

All Master's Theses

Colored slides were established as the discriminative stimuli for "truth" and "lying." Experimental subjects were commanded to emit both positive and negative statements in the presence of these stimuli concerning previously established neutral picture-slides. Subsequently, the real opinion of each subject was recorded. The hypothesis that those statements made in the presence of discriminative stimuli would effect judgments was not supported. The only significant main effect was that of the command variable. Suggestions for further study were given.

The Role Of Stimulus And Label Familiarity In Concept Learning, David W. Philips

All Master's Theses

Performance on a concept learning task was investigated by employing familiar and unfamiliar stimulus patterns, three pretraining conditions, and two conceptual rules. Subjects were given either observation or preliminary paired associate practice in labeling shapes with meaningful or nonsense labels and were then required to solve a concept learning task to criterion. It was found that tasks involving familiar stimuli were learned more rapidly than those involving unfamiliar stimuli, and that meaningful verbal pretraining for unfamiliar stimuli resulted in more rapid learning than observation or nonsense label pretraining.

The Course Of Amnesia Up To Twenty-Four Hours After Non-Contingent Treatment As A Function Of The Footshock-Electroconvulsive Shock Interval, Thomas C. Whitaker

All Master's Theses

This study tested specific predictions of the state-dependency hypothesis concerning the effects of footshock (FS)-electroconvulsive shock (ECS) treatment interaction on memory storage. Rats were trained in a water "T" maze to turn either left or right. Twenty-four hours later they received FS-ECS treatment. The FS-ECS intervals were .5 sec., 10 sec., 30 sec., and sham (no FS-ECS). Testing took place either 1, 6, 12, 18, or 24 hr. after treatment. Results indicated trends, but no significant evidence of the amnesia gradient being related to the FS-ECS interval.

Failure To Find A Memory Gradient In A State Dependency Paradigm, James Harold Thomson

All Master's Theses

Rats were trained in a passive avoidance task. Twenty-four hours later they were given a noncontingent footshock (FS) followed by electroconvulsive shock (ECS). ECS followed FS by different intervals ranging from .5 to 300 seconds in different groups. Subjects were tested 24 and 96 hours after the FS-ECS treatments for retention of the avoidance response. There were no statistical differences between the groups. This finding could not be taken as evidence that FS-ECS failed to produce amnesia since no evidence of passive avoidance conditioning in trained subjects not receiving FS-ECS.

Interanimal Transfer Of A Learned Response Tendency With Control For Autonomic Arousal, Landgrave Thomas Smith

All Master's Theses

In three experiments using 180 rats, extracts of brain protein were used for interanimal transfer of an avoidance response from donors to recipients. In the first experiment it was found that avoidance learning in donors produced a response transfer, but autonomic arousal did not. The second experiment confirmed these results, and demonstrated a response transfer after a single donor training trial. The third experiment confirmed the results of the first two, and the recipient response strength showed evidence of extinction and spontaneous recovery.

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.

The Relationship Of Dogmatism And Internal-External Control To Psychological Reactance, Edward J. Schau

All Master's Theses

One hundred ninety-two Introductory Psychology students volunteered for credit to complete the Rokeach Dogmatism Scale and the Rotter I/E Scale. The students were also asked to fill out a questionnaire, obstensibly from the administration, asking them to rate the favorability of the first five periods of the day on a scale of 1-100. Two weeks later 94 of the above students, serving as controls, were asked to fill out the identical questionnaire again. They were told that the previous ones had been lost. The 98 remaining students, serving as experimental subjects, received additional information. E said that he had heard …

The Cathartic Effects Of Aggressive Responses Directed Toward An Inanimate Object, Timothy William Creston

All Master's Theses

This study was intended to test the catharsis of aggression hypothesis which in part holds that aggressive responses directed towards an inanimate object will have a tension reducing effect and result in a lowering of residual hostility.

Effects Of Volition And Justification On The Arousal Of Dissonance During Performance Of A Dull Task, George Roger Schoenhals

All Master's Theses

The present study seeks to add a modest degree of clarification to the present condition of dissonance theory. More specifically, its main purpose is to help define certain conditions for the arousal of cognitive dissonance.

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.
