Female song in black-capped chickadees (Poecile atricapillus): acoustic song features that contain individual identity information and sex differences.

abstract：:In experiment 1, rats were trained in a within-subjects design to discriminate durations of a filled interval, and durations of an empty interval (an unfilled interval marked at the beginning and end by a 500 ms tone). Training and psychophysical testing was conducted with three sets of anchor durations. Rats made mor...
