Identify: Operational Definition

Read the research scenario and identify the following:

A group of cognitive psychologists examined the effect of noise on memory. Male and female college students were randomly assigned to memorize a list of words either in a noisy or quiet classroom. Participants were given 10 minutes to memorize a list of 30 words and then were asked to recall as many words as possible. The researchers recorded the total number of words recalled correctly. On a questionnaire, participants were asked to indicate their level of anxiety during the task. The results revealed that participants had better recall in the quiet room and also less anxiety than those in the noisy room.

Ans) A group of cognitive psychologists examined the effect of noise on memory. Male and female college students were randomly assigned to memorize a list of words either in a noisy or quiet classroom. Participants were given 10 minutes to memorize a list of 30 words and then were asked to recall as many words as possible. The researchers recorded the total number of words recalled correctly. On a questionnaire, participants were asked to indicate their level of anxiety during the task. The results revealed that participants had better recall in the quiet room and also less anxiety than those in the noisy room.

In this Memory(A) is a dependent variable......which depends on male and female so it is dependent variable.

In this number of words recalled correctly(B) is a operational definition....as we want the words to remember by men and women....the words recalled correctly is a operational definition.

In this noise(C) is a independent variable...as it is must in one room and the other is quite....so it is independent.

In this anxiety level(D) is a mediating variable.....as the men and women are participated in this memory recall in both noise and quite rooms.

In this men and women(E) is a subject variable.....as men and women are participated.
