Effects of 20-min audio-visual stimulation (AVS) at dominant alpha frequency and twice dominant alpha frequency on the cortical EEG.
The effects of audio-visual stimulation at the dominant alpha frequency and twice dominant alpha frequency on the EEG were investigated. An eyes-closed baseline EEG determined each subject's dominant alpha frequency. Subjects were stimulated at their dominant alpha frequency and at twice dominant alpha frequency for 20 min on two occasions. A 30-min post-session eyes-closed EEG was recorded after each session. Power data were analyzed for 19 locations in six bandpasses using repeated-measures ANOVAs and appropriate post-hoc tests. Alpha stimulation significantly increased power over baseline levels in the delta 1, delta 2, theta, beta 1 and beta 2, with significant effects remaining 30 min later in beta 1. Twice alpha stimulation significantly increased theta, beta 1 and beta 2 power over baseline levels, with significant effects remaining 30 min later in theta, alpha, beta 1 and beta 2.

Temperature acquisition as a function of the computer-based biofeedback system utilized: an exploratory analysis.
Thermal biofeedback is widely used to treat various clinical disorders. Given its widespread utility, and the variability among the biofeedback systems currently on the market, it is important to investigate which systems are most effective for training various skills. This study compared the performance of normal subjects on two different computer-biofeedback systems. Results indicated a significant difference in subject performance between the two systems. Limitations and implications of these findings are discussed.

An experimental acquisition of maladaptive behavior by shaping.
In an attempt to demonstrate possible maladaptive effects resulting from shaping, two Long Evans rats were trained to jump onto a platform, then to extend their noses downward over the edge to a point where, losing their balance, they fell. The results showed how behaviors such as reaching and rearing can be reinforced differentially to bring about completely maladaptive behavior.
