A blue key light provides reward for a bird on a VI60 sec schedule of reinforcement and a red light provides reward on a Vleo sec schedule. The bird would peck the red key more often. True False

Step 1
- VI60 sec schedule of reinforcement: This means that the reinforcement (reward) is given after a variable interval of time, with an average of 60 seconds. - Vleo sec schedule: This term seems to be a typo or an incorrect abbreviation. It might be intended to Show more…

A pigeon is in an operant chamber with two keys available to peck. Reinforcement for pecks at Key 1 is delivered on a VI-30 sec., while reinforcement for pecks at Key 2 is delivered on a VI-20 sec. This means that the keys can earn a maximum average of 2 and 3 reinforcers per minute respectively. What percent of responses will the pigeon direct at Key 1? a. 30 b. 50 c. 20 d. 40

You are an experimenter studying choice and the matching law. You have a pigeon in a very large enclosure, and you can move differently colored and shaped keys within the enclosure. You can program these keys to deliver reinforcers (grain) on any schedule of reinforcement you wish. Design an experiment to study matching when one key provides twice as much reinforcement as the other key. What schedule(s) of reinforcement will you use to best study choice and matching? To get matching, are there any other programmed consequences required? What will the expected results look like in terms of the distribution of responses between the alternatives? Now, suppose that you kept the reinforcement schedule the same, but you moved the keys so that they were a very long way away from each other. How might that affect the results and what is that called? Without changing the reinforcement schedule, what could you do to get the pigeon to respond equally to both keys?

18) The major advantage of free-operant methods over discrete trial procedures is that a. the animals learn more quickly. b. free operant methods provide the opportunity to observe changes in the likelihood of behavior over time, which allows for analysis of behavior in meaningful units. c. free operant methods can reveal an animal's preferences, which is what makes this procedure resemble natural behaviors. d. free-operant methods involve S-S learning, but discrete trial procedures involve S-R learning. 19) Which of the following is an example of positive reinforcement? a. receiving a time-out instead of a spanking b. turning off the radio when the DJ plays a song you dislike c. going out to dinner after winning an academic achievement award d. faking illness to avoid school in the morning. 20) In a study where pigeons were reinforced only if the pattern of pecks delivered to two keys was different from the previous 50 patterns, researchers determined that a. reinforcement increases stereotypy. b. behavioral variability can be the basis for instrumental reinforcement. c. reinforcement decreases intrinsic motivation. d. reinforcement decreases originality.
