The aim of this article was to provide experimental evidence that classical dissociation between levels of consciousness associated with memory retrieval can be explained in terms of task dependency and distinctiveness of traces. In our study phase, we manipulated the level of isolation of the memory trace by means of an isolation paradigm . We then tested these two types of isolation in a series of tasks of increasing complexity: a lexical decision task, a recognition task, and a free recall (...) task. The main result of this study was that distinctiveness effects were observed as a function of the type of isolation and the nature of the task. We concluded that trace distinctiveness improves subsequent access to the trace, while the level of trace distinctiveness also appears to determine the possibility of conscious or explicit retrieval.

Over the last half century, neuropsychologists, cognitive psychologists and cognitive neuroscientists interested in human memory have accumulated evidence showing that there is not one general memory function but a variety of memory systems deserving distinct functional entities. The first attempts to organize memory systems within a taxonomic construct are often traced back to the French philosopher Maine de Biran, who, in his book first published in 1803, distinguished mechanical memory, sensitive memory and representative memory, without, however, providing any experimental evidence (...) in support of his view. It turns out, however, that what might be regarded as the first elaborated taxonomic proposal is 14 centuries older and is due to Augustine of Hippo, also named St Augustine, who, in Book 10 of his Confessions, by means of an introspective process that did not aim at organizing memory systems, nevertheless distinguished and commented on sensible memory, intellectual memory, memory of memories, memory of feelings and passion, and memory of forgetting. These memories were envisaged as different and complementary instances. In the current study, after a short biographical synopsis of St Augustine, we provide an outline of the philosopher’s contribution, both in terms of questions and answers, and focus on how this contribution almost perfectly fits with several viewpoints of modern psychology and neuroscience of memory about human memory functions, including the notion that episodic autobiographical memory stores events of our personal history in their what, where and when dimensions, and from there enables our mental time travel. It is not at all meant that St Augustine’s elaboration was the basis for the modern taxonomy, but just that the similarity is striking, and that the architecture of our current viewpoints about memory systems might have preexisted as an outstanding intuition in the philosopher’s mind.

The use of remember–know judgments to assess subjective experience associated with memory retrieval, or as measures of recollection and familiarity processes, has been controversial. In the current study we had participants think aloud during study and provide verbal reports at test for remember–know and confidence judgments. Results indicated that the vast majority of remember judgments for studied items were associated with recollection from study , but this correspondence was less likely for high-confidence judgments . Instead, high-confidence judgments were more likely (...) than remember judgments to be associated with incorrect recollection and a lack of recollection. Know judgments were typically associated with a lack of recollection , but still included recollection from the study context . Thus, although remember judgments provided fairly accurate assessments of retrieval including contextual details, know judgments did not provide accurate assessments of retrieval lacking contextual details.

The ordinary understanding and ascription of mental states is a multiply complex subject. Widely discussed approaches to the subject, such as functionalism and the theory-theory (TT), have many variations and interpretations. No surprise, then, that there are misunderstandings and disagreements, which place many items on the agenda. Unfortunately, the multiplicity of issues raised by the commentators and the limitations of space make it impossible to give a full reply to everyone. My response is divided into five topics: (1) Which version(s) (...) of functionalism are candidates for an account of folk psychology, and is any such version satisfactory? (2) Where does TT stand in light of the two target articles and commentaries? (3) Does a phenomenological story provide a promising account of mental states, and is there special first-person authority about them? (4) What are suitable methodological assumptions for our subject matter? (5) How well does the simulation theory fare as an account of third-person mentalistic ascription? (shrink)

The ability to imagine hypothetical events in one’s personal future is thought to involve a number of constituent cognitive processes. We investigated the extent to which individual differences in working memory capacity contribute to facets of episodic future thought. College students completed simple and complex measures of working memory and were cued to recall autobiographical memories and imagine future autobiographical events consisting of varying levels of specificity . Consistent with previous findings, future thought was related to analogous measures of autobiographical (...) memory, likely reflecting overlapping cognitive factors supporting both past and future thought. Additionally, after controlling for autobiographical memory, residual working memory variance independently predicted future episodic specificity. We suggest that when imagining future events, working memory contributes to the construction of a single, coherent, future event depiction, but not to the retrieval or elaboration of event details.

This study investigated whether the encoding and retrieval of plurality information and letter-case information of words in recognition memory can be inhibited. Response-deadline experiments using single words have indicted a controlled processing mode, whereas studies using meaningful sentences have indicated an automatic mode of processing plurality information. Two similar opposing views have existed on the processing of letter-case information. The abstractionist view contends that we retain the abstract lexical information and discard the superficial perceptual case information. The proceduralist view holds (...) that perceptual details cannot be separated from the lexical information. Using an intentional and an attention-diverted learning procedure and instructions to ignore plurality and case, we found that subjects experienced a consistent interference effect of changed plurality from study to test but slightly less interference from changed case, suggesting strong automaticity for plurality, and comparatively less automaticity, for case processing.

A modified Remember/Know paradigm was used to investigate reported subjective awareness during retrieval. Levels of processing was manipulated at study. Word pairs were presented during test trials, and participants were instructed to respond “remember” if they recollected one of the two words, “know” if the word was familiar in the absence of recollection, or “new” if they judged both words to be new. Participants were then required to indicate which of the 2 words was old . With the standard RK (...) proportions, deeper processing at study increased remember proportions and decreased know proportions, but this dissociation was not shown with the 2AFC proportion correct measure which instead demonstrated robust LOP effects for both remember and know trials, suggesting that the know proportion measure severely distorts the nature of LOP effects on familiarity.

Episodic memory is usually regarded in a Conceptualist light, in the sense of its being dependent upon the grasp of concepts directly relevant to the act of episodic recollection itself, such as a concept of past times and of the self as an experiencer. Given this view, its development is typically timed as being in the early school‐age years (Perner, 2001;Tulving, 2005). We present a minimalist, Non‐Conceptualist approach in opposition to this view, but one that also exists in clear contrast (...) to the kind of minimalism (‘episodic‐like’) espoused byClayton and Dickinson (1998)with regard to memory in food‐caching birds. While emphasising the nonconceptual elements of episodic memory (in common with the ‘episodic‐like’ approach) we also insist on the essentially phenomenological nature of the memory (as does the Conceptualist approach). We propose the third year of life as a plausible onset period. Our view is rooted in Kantian assumptions about the spatiotemporal content of experience (and thus of re‐experience) and about the synthetic unity of experience—and thus of re‐experience. We answer two objections to this position. (shrink)

Recognition memory performance reflects two distinct memory processes: a conscious process of recollection, which allows remembering specific details of a previous event, and familiarity, which emerges in the absence of any conscious information about the context in which the event occurred. Slow wave sleep and rapid eye movement sleep are differentially involved in the consolidation of different types of memory. The study assessed the effects of SWS and REM sleep on recollection, by means of the “remember”/”know” paradigm. Subjects studied three (...) blocks of 12 words before a 3-h retention interval filled with SWS, REM sleep or wakefulness, placed between 3 a.m. and 6 a.m. Afterwards, recognition and recollection were tested. Recollection was higher after a retention interval rich in SWS than after a retention interval rich in REM sleep or filled with wakefulness. The results suggest that SWS facilitates the process of recollection in recognition memory. (shrink)

Bowler, Gardiner, and Grice have shown a small but significant impairment of autonoetic awareness or remembering involved in the episodic memory experiences of adults with Asperger’s syndrome. This was compensated by an increase in experiences of noetic awareness or knowing. The question remains as to whether the residual autonoetic awareness in Asperger individuals is qualitatively the same as that of typical comparison participants. Three experiments are presented in which manipulations that have shown differential effects on different kinds of conscious awareness (...) in memory in typical populations are employed with a sample of adults with Asperger’s syndrome. The results suggest that the experiences of remembering reported by such individuals, although reduced in quantity, are qualitatively similar to those seen in the typical population. The results are discussed in the context of current theories of awareness in episodic memory. (shrink)

One of the most widely applied techniques used to examine associative memory errors is the Deese-Roediger- McDermott paradigm. The aim of the present studies was to demonstrate a Polish version of the DRM paradigm and to test the characteristics of memory illusions evoked by this procedure for both recall and recognition. A normative study was conducted to prepare Polish stimuli material sharing similar characteristics as the lists in the English language version. Subsequently, the lists were applied to examine the effect (...) of prior recall on recognition, as well as the influence of retention interval on recall. The results revealed that the Polish version of the DRM paradigm induced a robust effect of false recall and recognition. Moreover, it was revealed that immediate recall of a single list led to a higher rate of both correct and false recall and that prior recall positively influenced recognition, leading to a higher rate of hits.

This study was aimed at investigating whether the retrieval of episodic information is more likely to be associated with the recognition of personally familiar faces than voices. Hence, the proportions of episodic memories recalled following the recognition of personally known faces and voices was assessed, using a modified version of the Remember/Know paradigm. Present findings showed that episodic information was more often retrieved from familiar faces than from familiar voices. Furthermore, this advantage of faces over voices was significant even when (...) face recognition was rendered similar as that for voices by blurring the faces. The same pattern of results was observed regarding semantic information retrieval . These results and their implications for person recognition models, as well as the potential role of the relative distinctiveness of faces and voices, are discussed. (shrink)

The process-dissociation procedure was developed to separate the controlled and automatic contributions of memory. It has spawned the development of a host of new measurement approaches and has been applied across a broad range of fields in the behavioral sciences, ranging from studies of memory and perception to neuroscience and social psychology. Although it has not been without its shortcomings or critics, its growing influence attests to its utility. In the present article, we briefly review the factors motivating its development, (...) describe some of the early applications of the general method, and review the literature examining its underlying assumptions and boundary conditions. We then highlight some of the specific issues that the methods have been applied to and discuss some of the more recent applications of the procedure, along with future directions. (shrink)

We investigate the common development of children’s ability to “look back in time” and to “look into the future” . Experiment 1 with 59 children 5 to 8.5 years old showed mental rotation, as a measure of prospection, explaining specific variance of free recall, as a measure of episodic remembering when controlled for cued recall. Experiment 2 with 31 children from 5 to 6.5 years measured episodic remembering with recall of visually experienced events when controlling for recall of indirectly conveyed (...) events . Quite unexpectedly rotators were markedly worse on indirect items than non-rotators. We speculate that with the ability to rotate children switch from knowledge retrieval to episodic remembering, which maintains success for experienced events but has detrimental effects for indirect information.
