The Effect Of Multiple Electroconvulsive Shocks Upon Rotational Activity In Rats, Thomas Lee Hall

Psychology ETDs

Multiple ECS treatments were administered to rats in order to assess the effects of electroshock upon rotational behavior. Since CA systems have a demonstrated role in the determination of rotational activity, alterations in behavioral asymmetry would suggest underlying changes in the intrinsic asymmetry of CA projections. If ECS, in turn, were to alter CA function, then one would expect ECS to also alter rotational asymmetry. In order to test this hypothesis, animals were given ECS daily for eight consecutive days. Measures of amphetamine-induced rotational activity were obtained from each animal prior to the first shock treatment and forty-eight hours following …

The Effects Of Anticipated Evaluation On Individual Brainstorming Performance, Barbara Kane Maginn

Psychology ETDs

Experimental investigations of the relative effectiveness of group versus individual brainstorming procedures have consistently reported the finding of individual brainstorming superiority. Several hypotheses concerning the nature of the inhibitory factor or factors operating in the group situation have been postulated. One which has been mentioned frequently involves postulation of the presence of anticipated evaluation in brainstorming groups. That is, it has been hypothesized that group members may believe that other members will evaluate critically ideas which they produce. As a result, freewheeling production of ideas may be suppressed in the group context. The present study manipulated different conditions of anticipated …

Effects Of Labels On Recognition Memory For Ambiguous Visual Forms, Marvin Charles Mccallum

Psychology ETDs

Memory for visual forms can be assessed in two separate ways. The most common approach is to assess the degree to which a form is accurately remembered. A less common approach is to assess the type and degree of change in form memory. The present experiment investigated the role of a single suggestive label in affecting both accuracy and qualitative change of recognition memory for ambiguous visual forms. Each of 240 subjects was briefly shown a single ambiguous form which represented the geometrical average of the anatomical characteristics of the two animal forms used to construct it. Just prior to …

The Effects Of Alcohol And Expectancy On Fantasy And Aggression In Male Social Drinkers, Michael R. Rodriguez

Psychology ETDs

Research has indicated a complex relationship between alcohol and aggression involving personality as well as situational variables. Recently it has been found that expectancy of receiving alcohol has a more potent effect (on many behavioral measures including aggression) than does actual receipt of alcohol. In addition, alcohol has been found to increase power fantasies in males, leading many researchers to associate power fantasies with powerful actions such as aggression. The present study examined the effects of alcohol and expectancy upon aggression and power fantasies in male social drinkers. In the first phase of the study, 30 male college students over …

The Differential Effect Of Cognitive Style On Memory, Lee Tilford Davis

Psychology ETDs

Researchers and theoreticians have long assumed differences to exist in the attentional and learning processes between hysterical and obsessive-compulsive style individuals. This assumption of differences between the two cognitive styles has engendered limited research. Further, this research has utilized only the type of tasks employed in learning and memory experiments. The present study attempted to assess differences in the memories of hysterical and obsessive style individuals, moving from memory for word lists as assessed in previous research, to memory for information more typically utilized in a clinical situation.

Hysterical (Hy) and obsessive-compulsive (Pt) style subjects were obtained through the administration …

Effects Of Constant And Varied Input Orders On Transfer Of Recall And Output Consistency, Gerald A. Clausen

Psychology ETDs

A transfer design was utilized to test differential predictions, derived from a one-process contiguity model and a two-process organizational model, concerning what is learned in the free recall situation under conditions of constant input order, in which the serial order of the list items remains the same for each presentation, and varied input order, in which the order is rescrambled for each presentation. Half of the subjects received constant input during training and half varied. In the test phase, half of the subjects in each of these two groups continued under the same condition received during training, while the other …

Effects Of Cognitive Complexity, Stress, And Cognitive Style On Pauses In Spontaneous Speech, Daniel B. Matthews

Psychology ETDs

Changes in the location, duration, and frequency of pauses in spontaneous speech were studied as a function of two levels of cognitive complexity, two of situational stress, and three levels of a dimension of the subjects' cognitive style (scanning). Since pauses reflect the location in a sentence where cognitive activity takes place, their variation in numbers and length allow inferences about underlying speech production processes. Subjects were classified into three groups based on the extensiveness of perceptual scanning, a personality characteristic hypothesized to be related to speech production processes. Scanning style was evaluated by means of factor scores derived from …

Selective Attention In Hyperactive Children Responsive To Methylphenidate, James Robert Allender

Psychology ETDs

Electrophysiological measures of cortical activity have indicated that hyperactive children who show a positive response to methylphenidate may have a deficit in inhibitory innervation. It has been suggested that this deficit may occur in the sensory and motor systems and result in two major symptoms of hyperactivity, poor attention and excessive motor activity. In this experiment sensory inhibition was evaluated for hyperactive and normal subjects using a shadowing task with various types of distractors. It was hypothesized that if attentional deficits of hyperactive subjects were due to their inability to inhibit irrelevant sensory input, then shadowing performance for the hyperactive …

A Validity Study Of The Creative Imagination Scale And Comparison Of Induction Techniques Under Plateau Conditions, Vernis Lloyd Crawford

Psychology ETDs

This study was divided into two parts. Part I was designed to evaluate the external validity of a new hypnotic scale (the revised version of the Creative Imagination Scale), while also creating a plateau (base rate) of responding to hypnotic suggestions for Part II. Part II was designed to evaluate the effectiveness of various hypnotic inductions under plateau conditions. Fifty-two introductory Psychology students at The University of New Mexico were randomly assigned to 12 groups. In Part I these groups received either the Barber Suggestibility Scale (BSS) and the Stanford Hypnotic Suggestibility Scale: Form C (SHSS:C) or the revised Creative …

Foreperiod Effects In Simple Reaction Time: A Variable Criterion Theory Analysis, John Mark Schnizlein

Psychology ETDs

A model of foreperiod effects in simple reaction time, based on Variable Criterion Theory, was proposed. In this model foreperiod varied within session affects the mean of the distribution of the response criterion in accord with the changing conditional probability of imperative signal occurrence. Increases in between-session foreperiod are hypothesized to increase the variability of the criterion because of errors in time estimation. These assumed criterion effects predict the existing empirical foreperiod effects if the growth of sensory strength is a negatively accelerated function of time. The results of Experiment 1 indicate that the mean of the criterion decreases with …
