Perceptual homeostasis and distress vocalization in puppies

Abstract

The present investigation concerned itself with a specific test of the concept of perceptual homeostasis Sixteen puppies were used to demonstrate that the presence of another puppy in a confining situation tends to decrease the level of emotional distress and thus to favor the maintenance of perceptually homeostatic conditions The indicator of emotional stress was yelping, in terms of number of yelps per unit time.
