This study is from a dissertation submitted in partial fulfillment of the requirements for the Ph.D. degree at the Institute for Child Study, University of Maryland.

Based in part on a PhD dissertation (Irwin) submitted to the University of Pennsylvania.

Subjects answered multiple-choice questions at three points in time. They worked alone, then in units of 1, 2, 3, 5, and 7 persons, and again alone. Performance on the task was to provide the following information: (1) initial ability level of subjects; (2) the ability of groups of differing size and leadership to utilize their resources; and, (3)…

Elderly adults (N=72) were presented a concept problem which varied as a function of type of solution shift and stimulus materials. Both trials to criterion and postshift error patterns were analyzed. Results indicated stimulus materials affected postshift performance and the elderly do respond in a dimensional fashion under some circumstances.…

Vocational Preference Inventory (VPI) was used to discriminate counselors rated as highly effective, as average, or as ineffective. Results indicated significant correlations between tested personality characteristics and rated job performances. Employment level, sex, age, certification, and degree status were of no significance in predicting…

Shift workers appear to be more satisfied in situations where swiftly rotating shifts have replaced fixed-period rotating shifts. (Author)

TWO SWITCH-LIGHT PROBLEMS WERE USED TO INVESTIGATE THREE VARIABLES THAT INFLUENCE PROBLEM-SOLVING PERFORMANCE--(1) THE NUMBER OF DISTRACTING RESPONSE ALTERNATIVES, (2) THE NUMBER OF AVAILABLE RESPONSE ALTERNATIVES, AND (3) THE NUMBER OF MINIMALLY REQUIRED RESPONSES. IN THE PROBLEMS USED, THE SUBJECT ATTEMPTED TO ACHIEVE A PARTICULAR PATTERN OF…

THE EFFECT OF ANXIETY ON COGNITIVE PROCESS HAS BEEN AN AREA OF EXTENSIVE RESEARCH. CONSIDERABLE EVIDENCE HAS INDICATED THAT HIGH ANXIOUS SUBJECTS ARE INFERIOR TO LOW ANXIOUS SUBJECTS ON COMPLEX COGNITIVE TASKS. ANOTHER FACTOR WHICH MAY INFLUENCE THE EFFECTS OF ANXIETY IS THE CONDITIONS UNDER WHICH A TASK IS PRESENTED. RECENT RESEARCH HAS SUGGESTED…

This critique is concerned with the validity of three basic assumptions underlying the performance-based teacher education program. These assumptions are 1) The teaching act is the sum of performances into which it is analyzed. 2) The performance unit is a matter of indifference, i.e., the number and character of the performance unit can vary…

The purpose of this experiment was to determine whether age differences noted when two tasks are performed concurrently can be accounted for in terms of age differences in single task baseline performance. Subjects were two groups of 12 eight-year-olds, and one group of 12 thirteen-year-olds. (CM)

This study indicates that a period of positive prior contact between a child subject and an adult experimenter may result in a relative decrease in performance for material reward dispensed by that adult experimenter. (Authors)

The effect of a realistic noise level (typing) on the intellectually challenging task of proofreading was examined. The results indicate noise subjects were poorer at identifying grammatical errors, worked slower and less steadily. (Author/DE)

The impact of false information concerning the effect of the menstrual cycle on test performance and subjects' perception of the adequacy of that performance were investigated. Women (N=65) were studied either during the premenstrual or midcycle phase. Subjects were given one of three interpretations: (1) they should do well because of their…
