Question 1

A time sampling method for measuring behavior in which the observation period is divided into a series of brief time intervals (typically from 5 to 15 seconds)
- At the end of each interval, the observer records whether the target behavior occurred throughout the entire interval, tends to underestimate the overall percentage of the observation period in which the target behavior actually occurred

Answer 1

Whole Interval Recording

Question 2

A term used by some authors as a synonym for A-B-A-B design; also used to describe experiments in which an effective treatment is sequentially or partially withdrawn to promote the maintenance of behavior changes

Answer 2

Withdrawal Design
