“…The analysis of meal patterns in freely feeding rats has led to considerable advances in our understanding of the substrates for eating behavior (LeMagnen, Devos, GaudiIliere, Louis-Sylvestre, & Tallon, 1973). Relatively little attention has been paid to events occurring within brief access times (Ghent, 1957;LeMagnen, 1967;Skinner, 1930;Smith & Duffy, 1957). In particular, no systematic study of possible interactions between access time, palatability, caloric density, and adaptation to the schedule, has been performed.…”
