This experiment investigated the tendency to escape from a situation requiring effortful responding. Five human subjects responded in a situation where the response mechanism required 20‐lb force to operate; responses were reinforced according to a variable‐interval schedule. A subject escaped from this situation by emitting a vocal response which produced a 60‐sec “easy period”. During the easy period the reinforcement contingency was switched to a response mechanism requiring 1 lb to operate. It was found that: (1) Escape responding could be conditioned and maintained by producing the easy period; the easy period did not maintain escape responding when the force requirement in the normal situation was equated with it. (2) The rate of escape responding was a function of the magnitude of the force normally required. (3) When easy periods were scheduled after fixed ratios, pausing from the end of the previous easy period to the first escape response was noted. It was concluded that a situation requiring high‐force responding is a negative reinforcer. The pattern of fixed‐ratio responding suggests that this reinforcer produces typical schedule control in human subjects.
