[Experimental psychophysiological studies on the effects of fenetylline and mefenorex].

16 male subjects were tested 1--7 h after the application of either 40 mg of the anorectic mefenorex, 50 mg of the stimulant fenetylline or a placebo by a battery of psychophysiological and psychological methods. Two problems of basic psychological interest were investigated: 1. covariation of appetite and central stimulation; 2. indicators of activation assessed by different parameters. The results concerning the first problem were inconclusive. The results with respect to the second show that pharmacological substances may cause dissociation of different indicators of activation.
