A microcomputer package for real-time skin conductance response analysis

A suite of programs has been developed to acquire data from a commercially available, highquality skin conductance meter, via a standard IEEE bus, on an Apple II or Apple lie microcomputer. These programs score and analyze stimulus-evoked skin conductance responses in a preset time window, and store the resultant data on disk, if required. Facilities for a manual override of the automatic scoring routine are available. The setup offers a method of scoring data as they are acquired; it uses currently recommended standards for skin conductance analysis and allows a high magnification of responses, without any need for continual monitoring, because of hardware facilities that automatically “back-off” a subject’s tonic skin conductance level.
