Cognitive Influences On Flavor Discrimination: Training Novices For Beer Flavor Differentiation, Rosalynn M. Peron

Psychology Theses & Dissertations

Four training techniques were employed to investigate the effects of increasing knowledge of beer flavor on novices' ability to differentiate among beers on the basis of taste. These techniques included (a) learning definitions of beer flavor terminology (Verbal Condition); (b) having additional experience with taste sensations (Taste Condition); (c) having a combination of the verbal and taste techniques (Verbal/Taste Condition); and (d) no training (Control Condition). After preliminary testing, 40 subjects (10 per training condition) were selected to participate in pre- and post-training tasks in which they rated similarity between beers, between beers and flavor-descriptive adjectives, and between flavor-descriptive adjectives. …

The Effect Of Intuition On Creativity As Discussed By Several Individuals Of Creative Genius, Mary Jean Campbell

Institute for the Humanities Theses

When the term intuition came into psychological parlance less than a century ago, the argument began over whether intuition could affect creativity, and whether it, in fact, existed at all as part of cognitive process. This paper will begin with a discussion of the meaning of intuition and some of the implications of that term, address the difficulties inherent in relying on self-report for information, and then turn to the statements of several well-known creative individuals about the role of intuition or intuition-related phenomena in their work.

The selection of creative individuals will be limited to those who have attained …

Children's Representation Of Spatial Information, Rebecca L. Beard

Psychology Theses & Dissertations

The present study utilized a multi-dimensional approach to examine children's communication of spatial information. Sixty male and female elementary school children, ages 6-7, 9-10, and 11-12, learned a route through a pedestrian maze with four color-coded inter sections and animal photographs to serve as landmarks. After learning the route to a specified criterion level, the children were required to complete three remaining tasks: a verbal recall task, a nonverbal reconstruction task, and a route reversal task. For each task the children were asked to provide a reason for their directional choice at each intersection. Analyses indicated developmental differences in performance …

Incidental And Intentional Recall Of Item Names And Spatial Locations, Lois Ann Scovel

Psychology Theses & Dissertations

Recent studies have indicated that there are no differences between the incidental and intentional recall of spatial location; whereas, intentional recall is superior to incidental recall of verbal information. In order to examine the variables that affect recall, second graders, fifth graders and adults were instructed to learn the location or the name of seven highly discriminable or less discriminable objects presented in a spatial array. Analysis of names recalled indicated that high discriminability enhanced recall, and that intent to learn facilitated recall, particularly for adult males. Recall increased with age, and females recalled more names than did males. Analysis …

The Relationship Of Cognitive Complexity-Simplicity To Occupational Role Perception, Raymond Boetcher

Psychology Theses & Dissertations

The present research investigates the relationship of cognitive complexity-simplicity to consensus in occupational role perception between subordinate and. supervisor. The research literature indicates that role consensus for specified positions is seldom found, and. that such disparities are well-documented for various educational roles. A sample of elementary school teachers and their immediate supervisors from three southeastern Virginia school systems were administered the Role Dimension Profile Scale in order to measure the importance of various behavioral role statements. Average ratings per role dimension were computed and difference scores were obtained. for each individual teacher and his or her supervisor. Teachers were divided …

Effects Of Practice On The Rate Of Gain Of Information In A Paper And Pencil Task, Dennis Howard Jones

Psychology Theses & Dissertations

Investigations into the effects of practice on choice reaction time (CRT) performance and the rate of gain of information have produced confusing and often contradictory results. This seems to stem from the fact that (1) a small number of subjects were utilized and (2) there were an insufficient number of experimental conditions. In the present experiments, the author has developed a Reaction Time Battery (RTB) that allows a large group of subjects to be tested efficiently and economically. Using three levels of stimulus uncertainty (1, 2, or 3 bits) factorial to two levels of S-R compatibility (low and high), Experiment …

The Ability Of Young Children To Recognize Facial Photographs Of Young Children, Young Adults, And Senior Citizens, Barbara Bell Bruff

Psychology Theses & Dissertations

A review of the literature on facial recognition including a description of its development from birth to old age, hypothesized reasons for its unique development, and factors which affect it, reveals the need for facial recognition studies involving the young child. Twenty children (10 males, 10 females) at each of three ages (3, 5, and 7 years) were presented with 30 pictures of persons of both sexes from three age groups (3-7, 18-25, and 50 years and above). A testing procedure followed in which each child was asked to pick out the test picture from a photo album page with …

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 …

The Retention And Maintenance Of An Information Processing Skill, Jerry Willard Hedge

Psychology Theses & Dissertations

In the performance of most skilled activities, there are definite limits to the proficiency attainable by an individual. These limits and how they affect the retention and maintenance of a skill are of major interest to performance-- assessment research. While much is known about verbal and motor skill retention, very little research has focused on the long~term retention and maintenance of information processing skills. The purpose of the present investigation was to determine the extent to which the information processing skills involved in a typical choice reaction time (CRT) task are retained and maintained over periods of two to eight …

The Use Of Picture-Symbol Pairings To Demonstrate Fading In Preschoolers Of Normal Intelligence, Donna Edwards Slaughter

Psychology Theses & Dissertations

Forty preschoolers were exposed to one of four groups in which the manner of presenting a stimulus, which consisted of a picture and a symbol, was varied. In the Standard (Std.) group, picture and symbol were ~f equal visibility, while the picture gradually became less visible over successive trials in the Fade· Picture Out (FPO) group. The Increase Symbol Size (ISS) group had the picture remain clearly visible and the symbol gradually increase in size while the Fade Picture Out-Increase Symbol Size (FPO-ISS) group had both the picture become less visible and the symbol increase in size over trials. A …
