Response Latency As A Function Of Hypothesis Testing Strategies In Concept Identification, Richard T. Fink

Psychology ETDs

The ability of Levine’s subset-sampling assumption to account for the gradual decrease in response latency following the trial of the last error was investigated in two experiments. Levine’s account assumes that Ss monitor a set of hypotheses (H) and reduce the set until only the correct H remains. This assumption leads to the prediction that latencies will decrease until S holds only the correct H and will remain constant thereafter. Levine’s assumption was tested by employing a distributed stimulus set composed of four binary dimensions and a procedure which required Ss to make an overt response in order to sample …

Baseline Response Rate And The Effect Of A Stimulus Which Precedes Response-Independent Reinforcement, William M. Arnold

Masters Theses

The relationship between baseline response rate and the effect of presenting a stimulus followed by response-independent reinforcement on baseline response rate was investigated in this study. Six pigeons were divided into two equal groups, one of which was conditioned to key peck on a VI-DRH schedule of food reinforcement, the other on a VI-DRL schedule of food reinforcement. Once responding had stabilized, a tone was introduced seven times during each session followed by a response-independent food reinforcement. The results indicated no change in the response rate of the VI-DRH group during the tone, and acceleration of responding during the tone …

Effects Of Verbal Reinforcement On Children's Responses To Three Subtests Of The Wechsler Intelligence Scale For Children, James Thomas Russell Jr.

Electronic Theses & Dissertations

The purpose of this study was to investigate the effects of positive verbal reinforcement on the responses to three subtests of the Wechsler Intelligence Scale for Children. The subtests were comprehension, similarities, and vocabulary. These three subtests were given to thirty children of the Geary County, Kansas, Unified School System, whose chronological age ranged from ten years, one month to ten years, eleven months. Their intelligence quotients ranged from ninety-five to one hundred and five.

The responses to the three subtests were analyzed statistically. The results indicated that positive verbal reinforcement did significantly change the amount of verbal production and …

Parameters Of Reward For Mongolian Gerbils (Meriones Unguiculatus), Charles E. Snow

Electronic Theses & Dissertations

This experimental investigation was designed to test which of four rewards would elicit the fastest and most consistent running speeds from Mongolian gerbils (Meriones unguiculatus). The four rewards were: Purina Lab Chow, .045 grams Noyes Precision Pellets, Sunflower seeds, and Hamster feed. Twenty-four male gerbils (90-120 days old) were randomly assigned to a deprivation group (D) and trained in a straight alley runway under a restricted ration deprivation schedule for 70 acquisition and 35 extinction trials. A second group of 24 subjects (non deprived group, ND) were similarly trained while on a free feed schedule.

Each group was further divided …

The Effects Of Free And Forced Choice With A Time Gradient And Monetary Incentive In A Serial Learning Task, Ernest Joseph Lucier Jr.

All Master's Theses

This experiment was designed to determine the effects of free and forced choice within time gradients of five and eight seconds using monetary incentive on a serial learning task. A series of nonsense symbols were successively presented to thirty-six subjects whose task was to learn the serial with the least number of exposures.

Explorations In Personal Space., Alice Biernoff Hiat

Psychology ETDs

It has been observed by a number of workers that humans tend to maintain some degree of physical distance between themselves and other persons or objects. This "individual distance" (ID) is assumed to reflect an area surrounding the person that he regards as a part of himself, rather like a portable territory; this area is termed "personal space" (PS).

Though there have been several experimental studies of PS in humans, none has determined the test-retest reliability of ID, nor has individual consistency of relative size of ID over a range of situations been investigated. The present study was designed to …

The Function Of Prior Conditions Of Success Or Failure Upon Subsequent, Non-Related Tasks, William Martin

Masters Theses & Specialist Projects

A sample of 32 Ss were drawn from the third through sixth grades and success or failure conditions were experimentally induced. The effects of these conditions were then determined on a subsequent, non-related task; the Block Design subtest of the WISC. Results indicated that these conditions do have a significant (p<.01) effect on the subsequent performance, although, this significance diminishes rapidly over a period of delay (24 hours). The study is limited in scope and in sample, but research implications are numerous and should include varied exposure to the success-failure conditions and the related effects of varied time-lapse intervals. Attention should be given to the differential effects of the two conditions and to the possibility that success-failure orientations may be significant factors in determining the quality of subsequent performance.

The Modification Of Form And Color Responding In Young Children As A Function Of Differential Reinforcement And Verbaliziation., Joan F. Gusinow

Psychology ETDs

When young children are presented with a learning task composed of two dimensional stimuli that vary along both. a form and a color continuum, they solve the problem in a consistent and unidimensional manner. This response bias, or dimensional dominance, has in the literature been called a form or color preference. The results of developmental studies have indicated that children at the. youngest ages display a form preference which gradually shifts to a color preference by the age of 4-1/2 years and then this preference shifts back. to form. This lawful relationship has then explained by developmental theorists as being …

The Effects Of False Feedback And Stimulus Intensity Upon Simple Reaction Time:An Investigation Of The Variable Criterion Model., Kerm Henriksen

Psychology ETDs

The purpose of the present simple reaction time (RT) study was to evaluate the application of the variable criterion model to the effects of false feedback and stimulus intensity. The variable criterion model is a decision-theory approach relating stimulus intensity and response evocation. According to the model, stimulus intensity determines the rate of neural events or "impulses" originating from stimulus onset, whereas contextual and motivational variables determine the S's decision criterion, or the number of impulses that must accumulate before a response is made. The time required to reach the criterion value is the reaction time. Reaction time is thus …

The Effect Of Perceptual-Motor Training On Maladaptive Behaviors Of Emotionally Disturbed Children, Julia Frances Hall

Dissertations and Theses

Twenty emotionally disturbed children between the ages of six and twelve from three agencies providing special treatment for behavioral or emotional problems were the subjects for this study. The subjects were divided into two major diagnostic categories, withdrawn and acing out, and then matched in pairs by age and diagnosis. One half of each pair was randomly assigned to the experimental condition and the remaining halves were assigned to the control condition. Both the experimental and control groups contained five withdrawn and five acting out subjects. Four experimenters were used, and each experimenter worked with two or four experimental children …

An Analysis Of Climatic Influences On Aggression, Alan M. Gonick

Masters Theses

The effects of exposure to various climatic conditions were analyzed to determine whether these conditions could produce aggression or facilitate shock-elicited aggression. Paired rats and single monkeys were used as subjects. The effects of independent and simultaneous changes in temperature and relative humidity were investigated in an attempt to produce aggression. Temperature, relative humidity, and length of exposure to climatic conditions were varied to determine if these conditions would facilitate shock-elicited aggression. The climatic conditions investigated were ineffective in reliably producing aggression between rats and also in facilitating shock-elicited aggression with rats and monkey subjects. Exposure to temperatures above 24.4°C …

The Manifest Anxiety-Defensiveness Scale, Induction Of Threat To Self-Esteem, And The Resolution Of Dissonance, Dennis F. Gardner

Student Work

It has been suggested that self-esteem is a significant contributing variable in determining defensive behavior (Asch, 1948; Janis & Field, 1959; Lazarus & Longo, 1953; Rosenzweig, 1938; Sears, 1940). Several studies suggest that individuals of high and low self-ssteem (SE) manifest different patterns of response to the experience of success and failure (Altrochi, Parsons, & Dickoff, 1960; Stotland & Hillmer, 1962; Stotland, Thorley, Thomas, Cohen, & Zander, 1957). Further, Slock and Thomas (1955) and Altrochi, Parsons, and Dickoff (1960) have shown that persons with high SE tend to avoid threatening materials, while persons with low SE tend to approach and …

Exploratory Behavior As A Function Of Two Different Feeding Conditions In The Gerbil, Dennis A. Vanderweele

Masters Theses

Gerbils were fed under two different schedules for six weeks after base-line measurement of open-table-top exploratory behavior. One schedule was a variable schedule such that a variable food amount could be administered at any time or place within the S's environment. The other schedule was fixed as to amount of food, time of administration, and feeding area. Separate Ss were utilized under each schedule and total amounts of food per group was equal. Both groups were retested for exploration after termination of the six week feeding schedule and statistical comparisons were made to S's baseline exploration. The fixed-fed Ss showed …

The Relative Importance Of Structure And Individual Differences In Determining Behavior In Two Person Games, Ronald A. Flint

Psychology ETDs

Three factors have been proposed in the literature as determinants of game playing behavior. These are: a structural factor, a factor arising out of the interaction between the players, and an individual differences factor. A recent study was able to separate the structural factor from the combined effects of the interaction factor and the individual differences factor. This was done by using a within-subjects design and between-game correlations to uncover behavioral consistencies across different games. Between-game consistencies were found, thus indicating that the structural factor is not the sole determinant of game playing behavior. However, because the interaction factor and …

Television-Mediated Aggression And Its Effects On Children’S Level Of Aggressiveness, Thomas M. Ferguson

All Master's Theses

It was hypothesized that subjects viewing film-mediated aggressive models would perform more aggressive behaviors in the test situation, than either of the other two groups, despite the low similarity factor. Results failed to confirm this hypothesis. It was found that boys were more aggressive than girls across all treatment levels.
