This study adapted operant behavioral tasks for comparing cognitive functions in monkeys and children. Monkeys and children performed similarly on most tasks, with monkeys showing faster learning rates due to physical response differences.

Area of Science:

  • Comparative psychology
  • Cognitive neuroscience

Background:

  • Operant behavioral tasks are used to assess cognitive functions in non-human primates.
  • Adaptation of these tasks allows for cross-species comparisons.

Purpose of the Study:

  • To compare cognitive task performance between rhesus monkeys and human children.
  • To validate a battery of operant tasks for use in both species.

Main Methods:

  • A standardized battery of operant behavioral tasks was administered to 4- to 8-year-old children and 4-year-old rhesus monkeys.
  • Tasks assessed functions including short-term memory, attention, learning, and discrimination.

Main Results:

  • Monkeys and children demonstrated comparable accuracy across most tasks.

  • A significant difference was observed in response rate for the learning task, with monkeys responding faster.
  • This difference was attributed to motoric variations in response execution.
  • Conclusions:

    • Operant behavioral tasks can be effectively adapted for cross-species cognitive comparisons.
    • Monkeys and children exhibit similar cognitive processing on these tasks, with response speed being influenced by motor capabilities.
