11. Implicit memory is a form of long-term memory not involved in conscious awareness.12. Research suggests that both HFA and M-LFA individuals show strong implicit memory function. 13. The book is considered to be a major philosophical contribution to the analysis of implicit memory . 14. Implicit memories of stimuli do not require conscious recollection of the initial encounter of the stimulus.15. Research into implicit memory indicates that it operates through a different mental process from explicit memory. 16. This suggests that implicit memory does not rely on depth of processing as explicit memory does. 17. A process stored in implicit memory may be easy to carry out but difficult to verbalize. 18. The reasons for our preferences may reside in implicit memory and thus be unknown to us. 19. Studies concerning implicit memory in M-LFA individuals are sparse and further study is needed. 20. Implicit memory has been linked to phenomena such as skill acquisition, priming, and classical conditioning.
