ABSTRACT:
The control unit for switching on a teaching device for conveying optical and/or acoustical learning information which includes a transducer for converting the pulse, skin resistance, blood pressure or respiration as to intensity and rhythm into an electrical analog signal followed by a detector for delivering an electrical digital signal when the alpha-state of the test subject is reached. The detector controls a switching unit for switching on the teaching device when the digital signal is applied. The analog signal is additionally applied to a signal generator which feeds an output signal corresponding to the analog signal to a lamp and/or a loudspeaker for purposes of biofeedback.
