11: People who question whether the number of electric shocks administered to
an experimental confederate really measures aggressive behavior are questioning
the __________ validity of experiments that use this technique.

C: construct

     Correct

Construct validity asks the question is the measure (operational
definition) we are using to measure something really representative of that
thing?  Since examining whether
shocks (the analog) really measures the thing we are trying to measure
(aggressive behavior), this answer is correct.
