Physical Fatigue As A Discriminative Cue In Choice Learning In The T-Maze, Robert L. Detty

Theses, Dissertations and Capstones

It has been found that animals which have acquired a response while under the influence of a drug , fail to emit this response when subsequently tested while nondruggedo Likewise, animals which have acquired a response while nondrugged fail to emit this response when subsequently drugged. However, under both conditions, Ss emlt the response when retested in the original condition. either drugged or nondrugged. Thus, the presence of the response appears to be conditional upon the drug state of the organism during acquisition. This phenomenon has been called state dependent (StD) or dissociative learning (Overton, 1964). Dissociation apparently varies along …

The Effects Of Reduction In Dependence Upon Group As A Source Of Influence On Field Dependence, James L. Antram

All Master's Theses

Recent research has cast doubt on Witkin's stability hypothesis of the field-dependence-independence dimension. Prior research suggested reduction of external field influences results in a decrease in level of field-dependence. It was hypothesized for this study that a reduction in dependence upon a group as a source of influence would result in a concomitant reduction in level of field-dependence as measured by the Witkin Rod-and-Frame Test.

A Comparison On The State Dependent Effects Of Electroconvulsive Shock And Physostigmine On A Choice Task, Candace Susanne Brown

All Master's Theses

Two experiments compared the state-dependent effects of electroconvulsive shock (ECS) and physostigmine relative to a normal state (saline or no injection). Rats were trained in a water T maze using a discrimination-training paradigm. In Experiment 1, discrimination was found between the ECS- and normal state. However, response control was strongest in the ECS-0 treatment-training order and on non-ECS training sessions. In Experiment 2, dissociation also occurred but was more pronounced in the P-0 (physostigmine-saline) treatment-training order and on the saline training sessions. Results from both experiments indicate learning is most rapid in the treatment-no treatment training order and that a …

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.

The Effect Of Temporal Separation On Performance Of A Discrimination Task, Stanley Dale Winter

Masters Theses

Test trials, consisting of the selection of two color cubes from a set of three different color cubes, were presented with: (1) a 15-second time delay between trials, (2) a single-color selection task between trials, (3) an unrelated motor task between trials and (4) no interspersion between trials. All Ss performed the task with more accuracy when test trials were separated by the unrelated motor task. The lowest level of accuracy occurred when test trials were presented sequentially with no interspersion. Performance appeared to be facilitated by the temporal separation of test trials.
