Purpose of this experiment was to explore the effects of pre- and postshift stimulus similarity, type of shift, and difficulty of discrimination in the standard solution shift - concept identification paradigm. (Authors/CB)

Although children given tangible reward performed better than children given intangible reward, neither type of reward had an effect that was significantly different from the level attained by a control group which received no explicit reward at all. (Authors)

Investigated was whether the value of an event influences a subject's guess that the event will occur. (KW)

The relationship between expectancy and performance in a self-paced computer-assisted instruction (CAI) program is explored in this study. The hypotheses developed were that the subjects with high expectancy would perform better and require less instruction, set higher performance criteria for themselves, and have higher expectancy on a transfer…

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…

THIS ARTICLE PRESENTS BASIC PRINCIPLES OF PROPER SCHOOL LIGHTING, DRAWING DIRECTLY FROM THE NEW "AMERICAN STANDARD GUIDE FOR SCHOOL LIGHTING." PRINCIPLES FOR PROVIDING A COMFORTABLE AND EFFICIENT VISUAL ENVIRONMENT ARE THESE--(1) ANY SCHOOL LIGHTING SYSTEM SHOULD BE DESIGNED IN SUCH A MANNER THAT IT WILL CONTRIBUTE TO A CHEERFUL, FRIENDLY, AND…

THE CHANGING ROLES OF THREE VISUAL-SPATIAL ABILITIES (SPATIAL ORIENTATION, VISUALIZATION, AND PERCEPTUAL SPEED) IN THE PERFORMANCE OF GROSS MOTOR SKILLS AT SUCCESSIVE STAGES DURING THE LEARNING PERIOD WERE STUDIED. THE SUBJECTS CONSISTED OF 48 WOMEN, AGES 17 TO 24, WHO WERE EQUALLY ASSIGNED TO EITHER OF TWO SECTIONS AND SUBDIVIDED INTO THREE…

The effect of externally-mediated goal setting on intrinsic motivation was examined using a laboratory assembly task. College male subjects (N=80) were randomly assigned in a factorial design including two conditions of goal setting (assigned vs. no goals) and two conditions of initial task interest (interesting vs. boring task). The results show…

In a variable distance 10-trial ringtoss, it was found that success required that a subject exceed his expected score. Therefore, the probability of success was the probability of exceeding the expected score on the 10 throws (Ps10); and this is shown to be different from the probability of scoring a ringer in a single throw (Ps1) from the same…

The twofold research task of this investigation was (1) a systematic evaluation of professional orientation of Colorado newsmen; and (2) a determination of the relationship (if any) between the professional orientation of the newsmen studied and the actual performance of these newsmen's newspapers. The population for the study included all the…
