The Effect Of Ethanol And Hypoglycemia On Rat Performance In The Radial Arm Maze, Monica Ann Gaffney Jul 1998

The Effect Of Ethanol And Hypoglycemia On Rat Performance In The Radial Arm Maze, Monica Ann Gaffney

Psychology Theses & Dissertations

Both hypoglycemia (HG) and ethanol (ETH) intoxication can cause serious impairment in physiological and psychological functioning. Their combination could cause more severe cognitive impairment than either condition alone. This experiment investigated the effects of hypoglycemia, ethanol intoxication, and their combination on rat radial arm maze performance. Eleven male rats were trained to a stable, low error rate performance in achieving food rewards in an eight arm radial arm-maze. Rats were then given either insulin (2 units/kg) or saline in combination with ETH doses of 250, 500, 1000, or 1500 mg/kg 20 minutes prior to the maze run. Treatment order was …


Effects Of Goal Reward And Feedback Frequency On Motivation: A Control Theory Perspective, Jonathan Michael Balcerek Jul 1996

Effects Of Goal Reward And Feedback Frequency On Motivation: A Control Theory Perspective, Jonathan Michael Balcerek

Psychology Theses & Dissertations

The current study investigated the effects of feedback frequency and goal reward on subject motivation. Klein's (1989) control theory model of work motivation was used to conceptualize the method and hypothesis. Subjects performed a simple computer addition task. When we examined subjects who displayed medium to high mathematical ability, significant effects were discovered. Higher goal reward led to higher motivation. In addition, subjects with a low goal reward and high amounts of feedback displayed lower motivation than subjects with a high goal reward and high amounts of feedback and subjects with a high goal reward and low amounts of feedback. …


Animal-Word And Sound Test: An Auditory Cognitive Interference Effect, Jason L. Parker Apr 1996

Animal-Word And Sound Test: An Auditory Cognitive Interference Effect, Jason L. Parker

Psychology Theses & Dissertations

This study presented a method in which the Stroop Color Word Test can be adapted to an auditory form. This auditory test used a series of animal words, animal sounds and word-sound combinations. This "Animal-Word-and-Sound test" contained three subtests. The test tasks were to repeat a list of words, identify a list of animal sounds, and to identify the sound in a combined animal word-sound pairings (Both the animal's name and sound are presented simultaneously). An alternate form of this audio test was examined. The alternate form followed the same construction except in the final condition, the task was to …


The Effects Of Irrelevant Dimensions On The Predictive Value Of A Warning Signal, Ruth Justine Arnegard Oct 1988

The Effects Of Irrelevant Dimensions On The Predictive Value Of A Warning Signal, Ruth Justine Arnegard

Psychology Theses & Dissertations

Past research has neglected irrelevant dimensions of visual warning signals in choice reaction-time tasks. The present study examined the effects of an irrelevant dimension of a visual warning signal and that signal's value in predicting a response stimulus on choice reaction time. A warning signal, which was a geometric figure, appeared in the center of a VDT screen and was followed by one of two response stimuli (open circles). The predictive value of the warning signal was defined as the percentage of trials during which the warning signal accurately predicted the response stimulus by size and was manipulated in the …


Effects Of Encoding Variety And Concurrent-Task Practice On The Transfer And Retention Of Complex Skill, Peter S. Winne Apr 1984

Effects Of Encoding Variety And Concurrent-Task Practice On The Transfer And Retention Of Complex Skill, Peter S. Winne

Psychology Theses & Dissertations

The present study investigated the effects of dual-task practice and the variety of problems solved during practice on (a) the acquisition of procedural and declarative skills and the development of concurrent-task skills, and (b) the utilization and maintenance of two types of strategies. Strategies were defined as the use of different mixes of skills pertaining to procedures and specific declarative solutions. Two tasks--mental arithmetic and trigrams--were used to examine problem-solving skills and strategies both immediately following practice and again under delayed conditions. Eighty subjects were randomly assigned to one of four practice conditions by factorially combining practice mode (single- or …


Examination Of The Self-Starvation Phenomenon, Elizabeth Woodard Pitts Jul 1982

Examination Of The Self-Starvation Phenomenon, Elizabeth Woodard Pitts

Psychology Theses & Dissertations

Rats on restricted feeding schedules are able to maintain a stable body weight by reducing activity output. It has been found, however, that if rats on restricted feeding schedules are given access to activity wheels, activity increases and food intake decreases which results in severe gastric ulceration and death. The present study re-examined results which suggested food palabability (wet versus dry chow) was a significant factor in self-starvation. In addition, all prior research examining the self-starvation phenomenon (with only one exception using hamsters) fed nocturnal rodents during the normally non-active light portion of their daily cycle. The results indicated that …


Effects Of Sleep Loss On Information-Processing In An Absolute Judgment Task As A Function Of Task Difficulty, Frieda O'Steen Carlton Jul 1980

Effects Of Sleep Loss On Information-Processing In An Absolute Judgment Task As A Function Of Task Difficulty, Frieda O'Steen Carlton

Psychology Theses & Dissertations

The effects of 36 hours of sleep loss on information-processing were assessed in an absolute judgment task. Of the 24 subjects employed, 12 served in the sleep-loss (experimental) and control conditions, respectively. All subjects were tested individually for a total of ten sessions; the control group was tested on ten consecutive days, whereas the experimental subjects were tested every four hours over a 36-hour period of sleep loss, and at a recovery session following approximately 12 hours of rest and recovery. The task required subjects to make absolute judgments of the size of two small circles of light and to …
