Patterns of extinction of a detection-indicating response under escape-avoidance reinforcement

Rats conditioned to avoid .40 mA shock achieved asymptotic performance at about 80 per cent avoidance. Reducing shock to .25 mA resulted in a drop to about 60 per cent. Under .40 and .25 mA, essentially all unavoided shocks were terminated by an escape response. Reducing the shock from .40 to .10 mA resulted in rapid and complete extinction of both the avoidance and the escape response.
