proctoring enabled: chapter 6: quiz (proctored)10a vacationer is hoping to see some dolphins. the guide says they tend to show up in the morning, so the vacationer watches every morning. some mornings the dolphins show up. other mornings they do not. which schedule of reinforcement is in effect with the dolphin viewing?multiple choicefixed-ratiofixed-intervalvariable-ratiovariable-interval

Explanation:

A variable-interval schedule provides reinforcement (here, seeing dolphins) after an inconsistent amount of time has passed. The vacationer checks every morning, but the dolphins appear on some random mornings, not after a fixed number of attempts or a set time interval. Fixed-ratio and variable-ratio are based on number of responses, not time, so they don't apply. Fixed-interval would mean dolphins appear at a consistent set time, which they don't.

Answer:

variable-interval
