Figure 3. Instrumental responses following outcome delivery.

Figure 3

Instrumental response rates were measured during a 2-min interval following free delivery of food pellets in the chamber. Responses were classified as a Match if the outcome of the instrumental response matched the freely delivered food pellet, whereas responses were classified as a Mismatch if the outcome of the instrumental response did not match the freely delivered food pellet. Response rates prior to outcome delivery (baseline) were subtracted from responses following outcome delivery. * = Match significantly greater than Mismatch response rate. Error bars = ± 1 SEM.
