Kurzfassung:
A bstract : The auditory template theory—the conversion of memorized song to produced song using feedback as an error‐correction mechanism—is central to neurobiological studies of birdsong learning. The essence of the theory is the construction of a complex sound replica based on a set of both genetic and environmental instructions. These premises, as yet unchallenged, have stimulated much research on the process of vocal imitation. Two somewhat distinct, but closely related streams of research have emerged. One seeks to determine the neural mechanisms that underlie the formation, storage, and retrieval of vocal memories as a consequence of experience during a sensitive phase—the template concept in its purest form. The other aims at establishing an explanatory basis for genetically based species differences in auditory responsiveness; here, the prime focus is on innately specified templates that guide learning preferences in young, naïve birds. The chapter begins with an historical overview of conceptual issues. Then recent progress in the attempt to characterize template properties is reviewed, focusing on selected studies of sparrows, nightingales, and zebra finches. The chapter concludes with a discussion of research strategy and tactics, including suggestions for criteria that must be met in identifying neural substrates for template specification and localization. The chapter is intended to provide a conceptual framework for further progress in this critical area.
