Please check my answer thanks

Which of the following conditions is an example of an intervening variable ?

A painful stimulation applied just after the independent variable

B. A loud noise causing a startle reponse
C. Deperiving a subject of water 12 hours before training
D. Hunger in the subject animal

I picked C

c is probably the best answer.

To check if your answer is correct, let's first understand what an intervening variable is.

An intervening variable is a factor that comes between the independent variable (the variable being manipulated by the researcher) and the dependent variable (the outcome being measured). It can influence the relationship between the independent and dependent variables.

Now, let's consider each option to see if it fits the definition:

A. A painful stimulation applied just after the independent variable - This might influence the participant's behavior, but it does not come between the independent and dependent variables. Therefore, it is not an intervening variable.

B. A loud noise causing a startle response - This is a potential confounding variable as it may affect the dependent variable, but it does not directly come between the independent and dependent variables. It is not an intervening variable.

C. Depriving a subject of water 12 hours before training - This is a good example of an intervening variable. It is a factor that occurs between the independent and dependent variables. The restriction of water might have an impact on the participant's ability to learn during training.

D. Hunger in the subject animal - Similar to option C, hunger can be considered an intervening variable as it influences the relationship between the independent variable and the dependent variable.

So, based on the explanation provided, it looks like your answer of C, "Depriving a subject of water 12 hours before training," is correct as an example of an intervening variable. Well done!
