Conceptual Replication

Dr. Salt found that college students (ages 18-23) performed better on a cognitive task when tested under a low noise condition than a high noise condition. Dr. Aludard wants to repeat the study by adding age as a variable (18-23 and 65-74). Dr Aludard predicts an interaction between the age and noise variables. Dr. Aludard is questioning the _______ validity of the original study.
