ATTACK BEHAVIOR AS A FUNCTION OF MINIMUM INTER-FOOD INTERVAL

Pigeons were exposed to a procedure in which food was presented after a fixed period of time had elapsed, provided no attack against a nearby stuffed pigeon had occurred during the last 15 sec of the period. As the minimum inter‐food interval was increased logarithmically through seven values from 15 sec to 960 sec, attack increased to a maximum and then decreased. For both pigeons, attack predominantly occurred after, rather than shortly before, food deliveries. 1969 Society for the Experimental Analysis of Behavior
