Abstract:
The following complications were introduced into the delayed reaction tests used in the preceding investigations: (1) disorientation and distraction during delay; (2) presentation of two delayed reaction problems concurrently; (3) shifting of containers (within the animal’s view) during the delay period. The distraction tests showed that the animals were not depending upon gross bodily orientation during the period of delay and that “Hunter’s ‘kinaesthetic sensory ideas’ would be the simplest possible explanation of their behavior.” Some of the old-world monkeys solved two delayed reaction tests concurrently. Lemurs and South American monkeys (platyrrhine) did not solve the double delayed reaction problems. A gibbon gave a poorer record than the best of the macaques and baboons. The baboons gave the best performances
