Primate locomotor pattern repetitions, program clocks, and orientation to light

  • J. Lee Kavanau
  • Charles R. Peters


Remarkable locomotor pattern repetitions by small nocturnal primates in 122-cm activity wheels occurred during 4-hour light cycles with simulated twilights. Some of the repetitions owed their genesis almost entirely to a night-to-night concurrence of endogenous timing programs. Others depended on strong tendencies of the animals to orient relative to the position of light sources and enclosure environment. Still others were based partly on influences of twilight illuminance level on speed of locomotion.

In many aspects the primate locomotor behavior was very similar to that of previously studied rodents and carnivores.
