Different Characteristics

Familiarity and recollection are qualitatively different explicit-memory phenomena evident during recognition testing. Investigations of the neurocognitive substrates of familiarity and recollection, however, have typically disregarded implicit-memory processes likely to be engaged during recognition tests. We reasoned that differential neural responses to old and new items in a recognition test may reflect either explicit or implicit memory. Putative neural correlates of familiarity in prior experiments, for example, may actually reflect contamination by implicit memory. In two experiments, we used obscure words that subjects could not formally define to tease apart electrophysiological correlates of familiarity and one form of implicit memory, conceptual priming. In Experiment 1, conceptual priming was observed for words only if they elicited meaningful associations. In Experiment 2, two distinct neural signals were observed in conjunction with familiarity-based recognition: late posterior potentials for words that both did and did not elicit meaningful associations and FN400 potentials only for the former. Given that symbolic meaning is a prerequisite for conceptual priming, the combined results specifically link late posterior potentials and FN400 potentials with familiarity and conceptual priming, respectively. These findings contradict previous interpretations of FN400 potentials as generic signals of familiarity and show that repeated stimuli in recognition tests can engender facilitated processing of conceptual information in addition to retrieval processing that leads to the awareness of memory retrieval. The different characteristics of the electrical markers of these two types of process further underscore the biological validity of the distinction between implicit memory and explicit memory.

There is clear evidence that aging has an effect on memory. However, not all memory processes suffer as one ages. In the current chapter, the authors review the distinctions between explicit memory (i.e., effortful storage and retrieval of information) and implicit memory (i.e., learning and memory that do not require conscious effort). They then review the evidence indicating that implicit memory does not decline at the same rate as explicit memory. They authors then discuss the possibility of using implicit memory processes (e.g. procedural memory), to aid explicit memory processes (e.g., declarative memory). Finally, they discuss the need and the opportunity to incorporate information and communications technologies into the lives of older adults in order to support memory and learning.

Previous studies have found that proficiency in a second language affects how the meanings of words are accessed. Support for this hypothesis is based on data from explicit memory tasks with bilingual participants who know two languages that are relatively similar phonologically and orthographically (e.g., Dutch–English, French–English). The present study tested this hypothesis with Chinese–English bilinguals using an implicit memory task – the cross-language repetition priming paradigm. Consistent with the result of Zeelenberg, R. and Pecher, D. (2003), we obtained reliable effects of long-term cross-language repetition priming using a conceptual implicit memory task. Overall, the four experiments support the Revised Hierarchical Model as they demonstrate that low fluency bilinguals can only access the conceptual representation of the second language via the lexical representation of the first language.

It is well documented that explicit (declarative, conscious) memory declines in normal aging. Studies have shown a progressive reduction in this form of memory with age, and healthy older adults (typically aged 65+ years) usually perform worse than younger adults (typically aged 18–30 years) on laboratory tests of explicit memory such as recall and recognition. In contrast, it is less clear whether implicit (procedural, unconscious) memory declines or remains stable in normal aging. Implicit memory is evident when previous experiences affect (e.g., facilitate) performance on tasks that do not require conscious recollection of those experiences. This can manifest in rehearsed motor skills, such as playing a musical instrument, but is typically indexed in the laboratory by the greater ease with which previously studied information is processed relative to non-studied information (e.g., repetition priming). While a vast amount of research has accumulated to suggest that implicit memory remains relatively stable over the adult lifespan, and is similar in samples of young and older adults, other studies have in contrast revealed that implicit memory is subject to age-related decline. Improving methods for determining whether implicit memory declines or remains stable with age is an important goal for future research, as the issue not only has significant implications for an aging society regarding interventions likely to ameliorate the effects of age-related explicit memory decline, but can also inform our theoretical understanding of human memory systems.

Abstract. One interpretation of levels of processing effects (LOP) on priming in implicit tests of memory is in terms of deficits in lexical processing during shallow study tasks. In two experiments the extent of lexical processing engaged in during standard shallow encoding tasks was manipulated by placing the encoding question either before or after the target stimulus. Clear evidence was found in explicit memory tasks that placing the question after the target stimulus increased the depth of processing of words presented in shallow encoding tasks. In contrast, there was no evidence of such an effect on the priming observed in implicit memory tasks. The results suggest that the role of lexical processing in LOP effects on priming requires further specification.

Age Range

How our memory is affected as we age has been given considerable attention over recent decades as we strive to understand the cognitive processes involved. Memory types have been identified as either explicit (declarative - related to episodes or semantics) or implicit (non-declarative – related to procedures, habits, or earlier priming). Studies have identified likely age-related decline in explicit but not implicit memory though there are opposing results suggested from other studies. It is thought cognitive reserve capacities might explain any non-decline as aging individuals use alternative or additional pathways to ‘remember’. This theory might be supported indirectly if older members remember material accurately but take longer to supply answers. In our current study we re-examined whether age-related differences in accuracy and speed of access in memory are present in both implicit and explicit memory processes and we increased the number of experimental age groups (from 2 to 3) - most previous studies have compared just two groups (young, and old). With three groups (young, middle-old, and older aged groups) we can identify trends across the age range towards deterioration or preservation of memory. We examined sixty-six participants (49 females; 17 males) aged 18 to 86 years (M = 50.27, SD = 21.06) from South-Eastern Queensland and divided these into younger (18 to 46 years of age), middle old (50 to 64) and older aged (65+) cohorts. Participants were administered tasks assessing implicit and explicit memory using computer presentations. Consistent with most prior research, no age differences were identified on accuracy in the implicit memory tasks (verbal and non-verbal, including priming), suggesting that memory for implicit material remains preserved. However, on the explicit memory tasks, older adults performed less accurately than the younger adults, indicative of decline in explicit memory as we age. The finding of a decline in explicit memory but no significant decline in implicit memory confirms most earlier research and is consistent with a view of modular decline rather than overall decline in memory with increasing age. In addition, differences found in speed of response in otherwise accurate implicit memory with older respondents significantly slower, suggests possible support for the cognitive reserve hypothesis.

Multinomial Processing Tree Model

In three experiments, we investigated how preventing the explicit encoding of conditioned stimulus–unconditioned stimulus (CS–US) pairings by imposing a secondary task at learning influences evaluative conditioning (EC) effects in a paradigm claimed to be conducive to implicit EC. We additionally used a multinomial processing tree model to examine how the resource depletion manipulation affects explicit and implicit memory contributions to EC. In all experiments, the EC effect largely vanished when a secondary task was employed that severely reduced participants’ explicit memory for the CS–US pairings. Furthermore, no evidence obtained for an implicit memory contribution to EC effects. In conclusion, the present research yields evidence for explicit learning, but no support for the contribution of implicit processes to EC in a paradigm claimed to facilitate implicit EC.
