{"pk":5263,"title":"Magnitude Effects of Sexual Reinforcement in Japanese Quail (Coturnix japonica)","subtitle":null,"abstract":"The effect of the magnitude of sexual reinforcement on the extinction of a running response was studied in quail. In Experiment 1, a group of subjects (L) received copulatory access to eight females, whereas a second group (S) received access to a single female. Both groups acquired the running response. During extinction, Group S showed a fast decrease in responding, whereas Group L persisted longer. In Experiment 2, males were allowed a choice between one or eight females. Preference for eight females demonstrated that males discriminated between the two reward magnitudes and that access to eight females had a larger reinforcing value than access to one female. The results are discussed within the context of the paradoxical reinforcement effects and the divergence in learning mechanisms in birds.","language":"en","license":{"name":"Creative Commons Attribution 4.0","short_name":"CC BY 4.0","text":"Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.
