Gruen, Gerald E.; Korte, John – American Journal of Mental Deficiency, 1973
Twenty-five retarded and 25 nonretarded children, mean age 16 and 9 years respectively, matched for mental age, performed two-bit (four-choice) and three-bit (eight-choice) problem solving tasks to determine whether group performance differences would increase with task complexity and whether performance of the retarded children would be poorer.…

Hornblum, Judith N.; Overton, Willis F. – 1974
Several studies have shown that the elderly do not perform well on the Piagetian problems of logical thinking; the present set of studies aimed at demonstrating that the elderly maintain the competence to solve such problems. The first study performed by the authors assessed performance of 60 noninstitutionalized middle-class elderly females on…

DAVIS, GARY A.; AND OTHERS – 1967
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…

BLATT, SIDNEY J. – 1963
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…

Schroth, Marvin L. – 1970
This study investigated the effects of informative feedback on a matching task with three combinations of verbal feedback and three levels of task complexity. The three types of feedback were right wrong (RW), nothing wrong (NW), and right nothing (RN). The three levels of task complexity were defined in terms of number of irrelevant stimulus…

RIMOLDI, H.J.A.; AND OTHERS – 1962
THE METHODS USED BY PHYSICIANS IN THE SOLUTION OF CLINICAL PROBLEMS WERE STUDIED. THIS WAS ACCOMPLISHED BY ANALYZING THE TYPE AND SEQUENCE OF QUESTIONS ASKED BY THE PHYSICIAN IN THE PROCESS OF UNDERSTANDING A PATIENT'S CONDITION. SEVEN TESTS WERE DESIGNED, TWO OF WHICH WERE THOROUGHLY EXPLORED. THESE TWO TESTS WERE ADMINISTERED SIMULTANEOUSLY TO…

Moravec, Milan – Training and Development Journal, 1978
Describes Bechtel Corporation's Organization Development (OD) system, which focuses on action/task identification, planning, operating decisions, and productivity. Presents eight-step process through which OD specialists help managers assess work-related problems (largely through interviews), action planning, implementation, and followup. Process…

Wasilewski, Bohdan K. – Journal of Experimental Psychology, 1972
Results supported the hypotheses that the emphasis on speed: (a) has a detrimental effect on the performance, (b) is inherent in a test-like situation, and (c) can be reduced by emphasizing in the instructions to Ss the detrimental effects of speed on the achievement of solution. (Author/CB)
