Abstract

After 100 years of experimental researches, two aspects of human memory are now treated separately in cognitive psychology; one is memory as conscious experiences, and the other is memory as information. In this paper, historical accounts are described with experimental researches on (a) implicit memory, i.e., memory without conscious recollection, (b) process dissociation procedures (PDP), i.e., a theoretical model and also a methodology to dissociate parallel cognitive processes, particularly conscious and automatic mental processes, and (c) false memory phenomena.
