Which of the following behaviors should be reinforced during the shaping of Sniffy’s bar-press behavior?

a. Rearing up and looking away from the back wall
b. Touching the bar and the hopper simultaneously
c. Rearing up with his feet against the back wall
d. Looking at the hopper before pressing the bar


c. Rearing up with his feet against the back wall
Answer feedback: Because the target behavior is the bar press, behavior that places Sniffy in close proximity to the bar and with a posture that makes bar pressing more likely to occur is included in the successive approximations to the bar press. The bar is located on the back wall, so that rearing up on that wall increases proximity to the bar. And rearing up with feet against the wall is a posture that favors eventual bar pressing.
