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

Indicate which of the following schedules of reinforcement is being used for each example: variable interval (VI): fixed interval (FI): variable ratio (VR): fixed ratio (FR) _____ At the beginning of the new term, your instructor announces that there will be five surprise quizzes over the course of the semester.

MATCH Four schedules of intermittent reinforcement with the examples provided (FI, FR, VI, and VR schedules). Definitions and examples: Fixed-interval (FI): Reinforcement is delivered following a set or constant time period. Typical examples include piecework offers. Fixed-ratio (FR): Reinforcement is delivered following a fixed number of responses. Salespeople are reinforced with sales on such a schedule. Slot machines deliver payoffs on a VR schedule. Professors might try to take advantage of the higher rates of responding seen under ratio schedules. Using an FR schedule, for example, professors could award points for each chapter summary or review completed. Variable-interval (VI): Reinforcement is delivered following a fluctuating time period. Students are reinforced on a VI schedule. Professors could also use VI or VR schedules to circumvent the post-reinforcement pauses seen in FI and FR schedules. For example, giving quizzes on a VI rather than an FI schedule - that is, giving "pop quizzes" - might encourage students to study more regularly. Variable-ratio (VR): Reinforcement is delivered following a variable number of responses. Professors could also use VI or VR schedules to circumvent the post-reinforcement pauses seen in FI and FR schedules. For example, giving quizzes on a VI rather than an FI schedule - that is, giving "pop quizzes" - might encourage students to study more regularly.
