Question

A researcher records the hair pulling behavior of three different children in a classroom and implements treatment at a different time for each child. The researcher is using a(n) _____ design.

a) Cross-sectional

b) Longitudinal

c) Multiple baseline

d) Cohort

Answer 1

The student's question refers to a research experiment where the treatment is applied at different times for different subjects, which describes a multiple baseline design used in behavioral psychology.

Step-by-step explanation:

The research described by the student involves testing different subjects over time with the implementation of treatment taking place at different times for each subject. This is known as a multiple baseline design. It's a type of experimental design used within behavioral psychology. Multiple baseline designs are helpful in establishing causal relationships without the need for random assignment to treatment and control groups.

In contrast, cross-sectional research involves studying different groups of individuals at the same point in time, longitudinal research involves studying the same group of individuals over a long period of time, and a cohort study follows a group of similar individuals over time. It's clear that choice (c) multiple baseline is the correct answer to the researcher's design employed.
