Abstract:

Social stimuli can have rewarding properties and promote learning. In birds, conspecific vocalizations like song can act as a reinforcer, and specific song variants can acquire particular rewarding values during early life exposure. Here we ask if, during adulthood, an acoustic signal simpler and shorter than song can become a reward for a female songbird because of its particular social value. Using an operant choice apparatus, we showed that female zebra finches display a preferential response toward their mate’s calls. This reinforcing value of mate’s calls could be involved in the maintenance of the monogamous pair-bond of the zebra finch. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
