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.

A: internal

    Incorrect.

Internal validity asks the question: "did we prove anything."  This means can
we attribute the outcomes of the experiment to the independent variables (what
we manipulated) rather than the confounding variables (the problems with the
experiment).  Since questioning whether shocks measure aggressive behavior is
not  related to internal validity, this answer is incorrect.  Put
differently, high internal validity means that we can show that the
different conditions of our experiment created changes in the number or
intensity of shocks given, but construct validity involves the
interpretation of the shock measure as a measure of aggressive behavior.
