Question

a) Fixed-interval
b) Variable-interval
c) Fixed-ratio
d) Variable-ratio

Answer 1

The most effective type of reward schedule at influencing behavior over a long period of time is the variable-ratio reinforcement schedule.

Step-by-step explanation:

The most effective type of reward schedule at influencing behavior over a long period of time is the variable-ratio reinforcement schedule.

In a variable ratio schedule, the number of responses needed for a reward varies, making it unpredictable and highly motivating. A fixed ratio schedule, where a set number of responses must occur before a behavior is rewarded, can lead to a high response rate but includes a pause after reinforcement. A variable interval schedule, in which reinforcement comes after unpredictable time intervals, produces moderate, steady response rates.

For example, slot machines in casinos operate on a variable ratio reinforcement schedule, where the player doesn't know how many lever pulls it will take to win, but the occasional reward keeps them engaged and motivated to continue playing.
