Abstract

An omission procedure was employed to study elicited pecking in the first component of a two‐component chain schedule. Both components were fixed‐interval schedules correlated with colored keylights. The first response following the initial‐link schedule produced a second fixed‐interval schedule. We studied several fixed‐interval lengths in two conditions: a standard response‐dependent condition and an omission‐contingent condition. The omission‐contingent condition differed from the response‐dependent condition in that responses during the initial fixed interval terminated the trial (omitting the terminal component and grain). If the terminal component was not omitted, a response following the terminal link's requirement produced 4‐s access to grain. Pigeons responded during more than 70% of the initial links in the omission‐contingent condition and responded during more than 90% of the initial links in the response‐dependent condition. In general, rates of responding were consistent with the percentage data. The responding in the omission condition suggests that there may be elicited pecking, in chain schedules using pigeons, that is not the result of contingent conditioned reinforcement. 1991 Society for the Experimental Analysis of Behavior
