A diverse set of stimuli, varying in shape, texture and odor, were used to enable measurement of general reactivity, rather than the species-specific patterns which may be elicited by particular stimulus configurations (TINBERGEN, 1951). The quantitative investigations of rodent and primate curiosity by BERLYNE (1950, 1955) and WELKER (1956a and b) constituted the immediate ante- cedents of the present study, although there have been other interesting descriptive reports concerning the reactions of small samples of caged mam- mals to novel objects (VOITONIS, 1949; INIIELDER, 1955; RENSCH, 1957). As the basic modern literature relating to the study of animal curiosity has been extensively reviewed in at least two recent publications (BERLYNE, 1960; WELKER, I96I), a further survey will not be attempted here. However, there is considerably earlier precedent for this type of research than has often been recognized. In his efforts to demonstrate the existence of higher 1) The primary data reported here
