Abstract
In a replication study, monkeys were tested for hand preference on three differing tasks: simple reaching for food presented on a board, choice of hand during a visual discrimination task and retrieval of food pellets from a row. Both laterality and degree of hand preference correlated significantly on two of the three tasks. Extremely little correlation was found across the other task combinations. Consistency of hand preference was greater within repetitions of a task than between any two tasks. The implication of these findings upon the search for a cerebral dominance underlying hand preference in the monkey is discussed.
