OBJECTIVE: To produce theoretical study about comparisons of cognitive and methodological aspects involved in the performance of Towers of Hanoi and London in normal individuals. METHOD: Narrative review of the literature. RESULTS: The performances in these instruments do not share the expected variance due to the apparent similarities in your structure and solution demand. Correlations significant, however moderate, among the two towers performance, were found reflecting the average of 75% of the nonshared variance. CONCLUSIONS: Both towers recruit different executive processes for task solution and cannot be used as exchangeable instruments.
