A method is described for the high-speed plotting of many independently generated elements in a computer-controlled display.     

THE EFFECTIVENESS AND TRANSFER VALUE OF TWO METHODS OF CONCEPT LEARNING

WERDELIN, I., BONDESSON, E. & LARSSON, G.-B. The effectiveness and transfer value of two methods of concept learning. Scand. J. Psychol. , 1971, 12, 198–204.–Two methods of learning are compared as to their effectiveness and transfer value, the "direction method", where principles are presented and exemplified, and the "discovery method", where the learner discovers the principles from examples. In an experiment with 12a pupils in grade five it was found that the direction method was superior to the discovery method in these learning situations, that the methods are differently effective with different materials, and that experience with one of the methods may transfer to the ability to learn new materials with either method. The connections between concept, method and previous experience are very complex, however.     

The effects of instructions,fixed rate of presentation,and complexity on free looking time

The effect of stimulus complexity, prior experience with a short or long fixed rate of presentation (FRP) and S’s knowledge concerning the purpose ot the experiment on free looking time (FLT), was examined. Results indicated that under all conditions, Ss view complex stimuli longer than simple. A long FRP produced longer FLT than did a short FRP for Ss uninformed of the purpose of the experiment, hut FRP had no effect on FLT for Ss who were informed.
