Humans and rhesus macaques perform visual maze tasks, revealing comparable processing of path turns but faster path length analysis in monkeys. Both species analyze mazes covertly from the center outward.

Area of Science:

  • Cognitive Neuroscience
  • Comparative Psychology
  • Visual Perception

Background:

  • Understanding visual processing and spatial attention in humans and nonhuman primates is crucial for comparative cognition research.
  • Developing standardized tasks allows for direct comparison of cognitive abilities across species.

Purpose of the Study:

  • To compare spatial attention and visual processing between humans and rhesus macaques.
  • To investigate how viewing time influences maze task performance.
  • To identify factors affecting response time in a visual maze task for both species.

Main Methods:

  • A novel visual maze task was designed for both human and rhesus macaque subjects.
  • Subjects fixated on a central start box and judged path completion via key presses or foot pedals.

  • Performance was assessed based on accuracy and response time, with variable viewing intervals and masking stimuli used.

    • Main Results:

    • Human performance accuracy increased with viewing time, plateauing at 500 ms with ~85% correct.
    • Response time in both species correlated with path parameters like turns, length, and exit status.
    • Monkeys processed path length units faster than humans, while turn processing time was comparable.

    Conclusions:

    • Covert, center-outward maze analysis occurs without saccadic eye movements in both humans and rhesus macaques.
    • The visual maze task effectively differentiates and compares visual processing and attention mechanisms across primate species.
    • Findings contribute to understanding shared and divergent cognitive strategies in primates.
