For nearly a century the experimental analysis of learning in animals has b
een divided into niche-related and general-process approaches, each emphasi
zing different procedures and conceptual strategies. After considering seve
ral current forms of rapprochement, I outline evidence for the integrative
hypothesis that niche-related learning provides the basis for results in tr
aditional general-process learning paradigms. Although the full ramificatio
ns of this View are not developed here, its advantages include: a clearer r
elation between laboratory and field results, conceptual and pragmatic guid
ance in developing new paradigms, and applying old ones to different specie
s, and circumstances: clarification of the laws, limits, and anomalies in g
eneral-process paradigms: and a more efficient path for inter-relating the
study of learning with neurophysiology, genetics, and evolution. (C) 2001 E
