Effect of CS Duration on Trace Conditioning of Mental Retardates

Abstract

The importance of CS duration in concurrent trace conditioning of the GSR and eyelid response was investigated with 32 retardates. Four treatment groups completed a 2-day training procedure involving habituation, acquisition, and extinction. Irrespective of response class, a long CS (1000 msec.) resulted in better conditioning than did a CS with a shorter duration (100 msec.). This finding could not be accounted for by either interstimulus or trace interval differences.
