In an experiment on the effects of communication on cooperation, researchers observed higher rates of cooperation if members were able to communicate with each other prior to doing the cooperative task than if they were not allowed prior communication. This illustrates a(n) ____ effect of communication on cooperation.
A) meta-analytic
B) correlational
C) main
D) interaction

Question

Quizplus · Accepted Answer

The higher rates of cooperation observed when members were able to communicate prior to the cooperative task indicate a main effect of communication on cooperation. A meta-analytic effect would involve synthesizing data from multiple studies, while a correlational effect would involve examining the relationship between two variables rather than the impact of communication on cooperation specifically. An interaction effect would involve the influence of communication on cooperation varying depending on other factors, such as the group size or the complexity of the task. However, the scenario provided does not mention any such factors.
