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.     

An inexpensive circuit for beta,alpha, theta,or delta EEG biofeedback

An inexpensive circuit is described for EEG biofeedback or measurement. The circuit is designed to interface easily with most basic EEG machines. It taps the output from a single recording channel of the basic EEG instrument and provides the following for each EEG band (beta, alpha, theta, and delta): (a) very selective bandpass discrimination, (b) variable center frequency, (c) variable threshold at which feedback will be provided, or the measurement made, and (d) use with any biofeedback stimulus or measurement device that one wishes to switch contingent with S’s EEG rhythms.
