In a study by Rosengren, Schein, and Gutiérrez (2010), scale errors committed by children between the ages of 18 and 29 months were recorded while they were at play in a laboratory preschool. The researchers placed miniature replica toys in the preschool classroom during specific time periods to increase the likelihood of observing scale errors. This study is an example of a:
A) naturalistic observational design.
B) case study design.
C) structured observational design.
D) single-subject experimental design.

Question

Quizplus · Accepted Answer

The study by Rosengren, Schein, and Gutiérrez (2010) used a structured observational design where the researchers manipulated the environment by placing miniature replica toys to observe specific behaviors (scale errors) in a controlled setting. A naturalistic observational design would involve observing children in their natural environment without any manipulation, a case study design would involve in-depth examination of one or a few individuals, and a single-subject experimental design typically involves manipulating variables to observe the effects on behavior.
