Question 1

response pattern produced: High Rate, post reinforcement pause, ratio strain possible

Answer 1

Fixed ratio

Question 2

Response parent produced: moderate - high rate, consistent, no PRP, ratio strain possible

Answer 2

Variable ratio

Question 3

Produces scalloped pattern of responding we’re a little behavior is produced early in interval but as interval nearest end rate of responding increases

Answer 3

Fixed interval

Question 4

Overall low consistent rate of responding with out post reinforcement pauses

Answer 4

Variable interval

Question 5

Lag reinforcement schedule
•Criteria for reinforcement is a response different from previous number of responses

• Leg five schedule must be different than last five responses

Answer 5

Response diversity

Question 6

HANLEY, : By pairing less preferred activity with established reinforcers through contingent delivery or through non-contingent delivery?

Findings:
-enhancing an activity with supplemental contingent reinforcement can shift choices tours activity

-Non-contingent pairing of an activity with established preferred stimuli can shift choices towards activity

BUT….. effects seem transient in general (does not persist after discontinuation of pairing)

Answer 6

Determinants of stimulus value can we make something preferred that was not already?

Question 7

Reinforcement lies between continuous reinforcement and extinction

Answer 7

Intermittent reinforcement

Question 8

Fixed time provides reinforcement at a fixed time since the last reinforcement, irrespective of whether subject has responded (Noncontingent schedule)

Variable time provide reinforcement at an average variable time since last reinforcement regardless of whether the subject has responded or not

Answer 8

Response independent stimulus delivery – also called NCR

Question 9

Prototype study: Deci 1971

Compared to possible completion of two groups

Following baseline observation, one group received a one dollar reward for completion. The other group did not. For reward group, puzzle completion decreased to be low initial baseline level following cessation of reward contingency, while stable completion levels were observed for a control group

Answer 9

Extrinsic reinforcement and intrinsic motivation
