Formation of Different Strategies of Competitive Foraging Behavior in Rats

  • PHYSIOLOGY
  • Published:
Bulletin of Experimental Biology and Medicine Aims and scope

We studied competitive interactions of rats during instrumental foraging behavior. Two groups of animals were revealed: rats with predominance of operant actions for getting food reinforcements (donors) and kleptoparasites that more often get food after instrumental acts of the partners. Intergroup differences began to appear and increased from 3-4 paired experiments. It was revealed that at the individual stage of learning the instrumental skill, donor rats were faster in learning and showed high foraging activity with shorter latency in comparison with kleptoparasites, which were initially slower and performed a large number of inter-signal actions in the form of unconditioned peeking into the feeder.
