Objective: To compare the influence of a food guide's shape on its effectiveness and efficiency to convey nutritional information. Methods: A between-subjects experiment was conducted by manipulating the graph's shape (circle, pyramid, or rainbow). Nutrition tasks were used to assess the effectiveness and eye-movement data (number/duration of…

Bat/ball contact produces visual (the ball leaving the bat), auditory (the "crack" of the bat), and tactile (bat vibration) feedback about the success of the swing. We used a batting simulation to investigate how college baseball players use visual, tactile, and auditory feedback. In Experiment 1, swing accuracy (i.e., the lateral separation…

This manual describes the scoring procedures for the Greenberger-Entwisle Need-Achievement Pictures. This instrument was developed (1) to provide a set of pictures suitable for a wide age range of subjects, (2) to increase the comparability of findings, and (3) to increase the reliability of measurement. General instructions for scoring the…

The six experiments presented in these two manuals were designed for use in any introductory or advanced undergraduate psychology course either partially or totally concerned with human cognition. One manual serves as the teacher's accompaniment to the actual experiments detailed in the student's manual. A list of textbooks which might be…

This document is a report on a course in nuclear science for the high school curriculum. The course is designed to provide a basic but comprehensive understanding of the atom in the light of modern knowledge, and to show how people attempt to harness the tremendous energy liberated through fission and fusion reactions. The course crosses what are…

The following topics are included in this document: (1) evaluation of plans for implementation of new systems; (2) macroevaluation of document retrieval systems; (3) microevaluation of retrospective searching; (4) evaluation of document acquisition functions; evluation of indexing and indexing languages; (5) evaluation of document screening; (6)…

This guide presents many new experimental designs for data analysis and reviews certain standard procedures. It is hoped that the treatment of the material will stimulate new applications since the emphasis of the guide is on the problems encountered in running experiments rather than on an elaboration of mathematical models. Discussed are:…

FAILURE OF A CLASSROOM EXPERIMENT IN PROGRAMED INSTRUCTION SCHEDULING BASED ON A CONTINGENCY CONTRACT BETWEEN TEACHER AND PUPIL WAS ATTRIBUTED TO LACK OF COMMUNICATION BETWEEN EXPERIMENTERS, TEACHERS, AND ADMINISTRATORS (TEACHER ATTITUDES DID NOT CHANGE), AND LACK OF OPTIMUM CLASSROOM CONDITIONS. TO CORRECT THESE, A NEW UTILIZATION MANUAL…
