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.

A Comparison Between Self-Paced And Instructor-Paced Instructional Systems, Laura Lee Winter

Masters Theses

Two college level systems of instruction derived from basic behavioral principals were compared. Community college students enrolled in two sections of an introductory psychology course served as subjects. Students in one section experienced a self-paced system of instruction. Students in the second section went through the course under an instructor-paced system of instruction. Students in the self-paced section received higher course grades and performed better on unit quizzes. However, the final examination performance for the two groups was about the same. Suggestions for further research are given.

Successive Discrimination Reversal Learning In The Rat Offspring As A Function Of Maternal Stress During Gestation, Miles A. Kowall

Masters Theses

This paper itself with the effect of prenatal stress on the learning ability of the offspring, parental emotionality on learning ability, and how these two factors interact. Female animals were categorized as either high or low emotional by measures in the open field and then further divided into shock or no-shock groups. This provided the stress condition. All females were stressed during pregnancy. Cross fostering and fostering techniques were used to provide more stringent control measures so as to be able to extrapolate prenatal influence from post natal artifacts. This resulted in a 2X2X3 analysis of variance matrix with error …

An Analysis Of The Relationship Between The Instructional Emphasis Of Two Filing Textbooks Commonly Used In Secondary Schools And Their Relation To The Filing Procedures In The Business Office, Patricia Ann Skinner

Masters Theses

This study compared the instructional material in two textbooks commonly used for high school filing instruction with the perceptions of records supervisors and office practice teachers.

A questionnaire was designed for each of the two major groups of respondents. Usable survey instruments were completed by supervisors of 67 offices in the Benton Harbor-St. Joseph area and office practice teachers in the 13 high schools in the same geographic area.

While the records supervisors and office practice teachers were in agreement on a number of points relating to the filing process and instructional emphases (using a rank-order mismatch formula), they were …

The Consideration Of Some Aspects Of Two Methods Used To Study Ion Association, Richard Karl Gard

Masters Theses

An investigation was made into the possibility of determining thermodynamic ion association equilibrium constants for salts important in the study of seawater using spectrophotometry and ion selective electrodes. Calcium sulfate was used as the test salt. The success of the spectrophotometric method was found to depend upon the choice of a suitable indicator and refinement of the proper instrumental techniques. The indicators investigated were 1-(2'-hydroxy-1'-benzeneazo)-2-hydroxynaphthalene, 1-(2'-hydroxy-5'-chloro-1'-benzeneazo)-2-hydroxynaphthalene, and ammonium purpurate (murexide). Ammonium purpurate was found to be the most suitable indicator. Spectra of these three indicators and their calcium complexes at pH 10 are included in the paper. The ion selective …

Efficacy Of Reinforcement In An Observational Paradigm, Charles M. Krizic

Masters Theses

Study investigated the effectiveness of reinforcement in an observational paradigm where the dependent variable was indicated by increased morphological resemblance of an observer (O) after viewing a model (M). The stimulus was a series of novel responses recorded on videotape with each child viewing the tape individually. The subjects were 32 Head Start males divided into four groups. The first group was administered verbal praise prior to the modeling session. The second served as the vicarious reinforcement condition and observed an adult praise the model. The third group received direct reinforcement during the test for acquisition. The control group received …

A Study Of Organochlorine Insecticides In Freshwater Crayfish -- Analytical Problems And Biomonitoring Survey, Robert C. Vanderjack

Masters Theses

Crayfish were collected from 3 sites on Polecat Creek, Coles County, Illinois in early spring, early summer, and late summer of 1972. Pesticides were extracted from the crayfish tissue in a one step procedure utilizing a Florisil elution column. Analysis was by electron capture gas chromatography. Pesticide residues in the nannogram range were analyzed and background contamination was an important consideration. Sources of background contamination were investigated and teflon stopcocks, Florisil, and residues on “cleaned” glassware were found to be major contamination sources. Distilled water used in flushing glassware should also be considered a potential contamination source.

Morphological And Physiological Effects Of 2,4-D On Gram-Negative And Gram-Positive Bacteria, John H. Rupnow

Masters Theses

Manometric, spectrophotometric, photomicrographic and quantitative biochemical techniques were employed to determine the morphological and physiological effects of 2,4-D on Gram-positive and Gram-negative bacteria.

The growth and motility of Gram-positive bacteria appeared to be more adversely affected than the growth and motility of Gram-negative species. The terminal oxidation, lysis, and chain length of both Gram-positive and Gram-negative bacteria did not appear to be affected by the concentrations used. The average cell size of both Gram-positive and Gram-negative bacteria was observed to increase after exposure to 1000 ppm 2,4-D. The normal leakage of amino acid and ultraviolet light absorbing cell constituents appeared …
