Social rehabilitation of addicts: a two-year evaluation.

This paper points out the relationship that exists between treatment approaches with drug addicts and sociodemographic characteristics of the communities affected. It has been shown that while poor and middle class communities show good results with methadone maintenance approaches, in the area of secondary drug abuse they show marked dissimilarities. Also, the reasons for discharge are markedly different.

Clinical applications of biofeedback: implications for psychiatry.

The authors briefly describe biofeedback techniques such as EMG feedback, temperature feedback, and heart rate feedback, along with reports from the literature about their application to specific problems such as subvocalization while reading, Raynaud's disease, cardiac arrhythmias, and epilepsy. Many clinical applications of biofeedback are aimed at inducing relaxation, a state that has important psychotherapeutic potential. The authors suggest that biofeedback could be used to reduce a patient's general level of arousal or as an adjunct to behavior therapy or insight therapy.

Target-set and response-set interaction: implications for models of human information processing.

However, when the targets formed a familiar set and subjects were not required to make explicit "no" responses, reaction time did not increase significantly as the target set increased in size from one to three.
