“…Numerous recent experiments have provided empirical support for the effect in both human (e.g., Block, 1982;Godden & Baddeley, 1975;Hintzman, Block, & Summers, 1973;Smith, 1979Smith, , 1982Smith, Glenberg, & Bjork, 1978) and animal (e.g., lobe, Mellgren, Feinberg, Littlejohn, & Rigby, 1977) research. However, the superiority of same-context testing has not been found across all experimental paradigms (e.g., recall vs. recognition) or instructional sets (see Block, 1982;Nixon & Kanak, 1981;Smith et al, 1978), indicating that the underlying mechanism or mechanisms governing contextual associations have specifiable boundaries of sensitivity.…”
