Schedule-induced aggression as a function of fixed-ratio value

D R Cherek et al. J Exp Anal Behav. 1970 Nov.

Abstract

Pigeons responding for food on fixed-ratio reinforcement schedules attacked live target birds when the ratio value was increased, but not when the value was decreased. The frequency of attacks peaked several days after ratio value change, and then gradually decreased to an original level.
