Using Errors by Guard Honeybees (Apis mellifera) to Gain New Insights into Nestmate Recognition Signals.

abstract：:When people misidentify everyday odors, as they often do, their errors may conceivably lie in faulty perceptions or in faulty access to the names. Discussions of the matter usually focus on the latter, as if people had no problems with perceptual accuracy. (The problem of faulty access may get attention because its hi...
