In the classic Blakemore and Cooper (1970) study, the researchers raised one group of kittens in a cylinder with vertical stripes painted inside, and a second group of different kittens in a cylinder with horizontal stripes on the inside.
The researchers were interested in measuring the effects of early stimulation on the development of the visual system in kittens. What type of research design was used in this study?
a. Two-Level, Double-Factor study with control group
b. Two-Level, Single-Factor study without control group
c. Multi-Level, Double-Factor study with control group
d. Multi-Level, Single-Factor study without control group
Question 2
Suppose you were reading about a laboratory experiment that was examining the effects of gender on artistic creativity.
The study determines that, relative to females, males tend to have lower creativity scores based on a standardized test of creativity. What type of research design is being used here?
a. Two-Level, Double-Factor study with a manipulated independent variable
b. Two-Level, Single-Factor study with a manipulated independent variable
c. Two-Level, Double-Factor study with a nonmanipulated independent variable
d. Two-Level, Single-Factor study with a nonmanipulated independent variable
