Ma. Latour et Sj. Mckelvie, EFFECTS OF TYPE OF INPUT AND TYPE OF PROCESSING ON RECALL HYPERMNESIA, Canadian journal of experimental psychology, 48(3), 1994, pp. 451-459
Twenty undergraduates participated in one of six conditions representi
ng two types of input (words, pictures) and three types of initial pro
cessing: imagery (generate object imagery or real-world imagery), sema
ntic (rate pleasantness or form a verbal association), and physical (r
ate complexity or judge the presence of a feature). After viewing 70 i
tems, subjects attempted to recall them four times. Except for physica
l processing of words, the number of items correctly recalled improved
over trials, demonstrating hypermnesia. Intrusions increased over tri
als in most conditions and appeared later within a trial for words tha
n for pictures. Of five alternative accounts of hypermnesia, these res
ults favour the sensory/semantic model of memory coding.
