Three hypotheses of forgetting from immediate memory were tested: time-based decay, decreasing temporal distinctiveness, and interference. The hypotheses were represented by 3 models of serial recall: the primacy model, the SIMPLE (scale-independent memory, perception, and learning) model, and the SOB (serial order in a box) model, respectively.…

How does the brain carry out working memory storage, categorization, and voluntary performance of event sequences? The LIST PARSE neural model proposes an answer that unifies the explanation of cognitive, neurophysiological, and anatomical data. It quantitatively simulates human cognitive data about immediate serial recall and free recall, and…

Knowledge of sequential relationships enables future events to be anticipated and processed efficiently. Research with the serial reaction time task (SRTT) has shown that sequence learning often occurs implicitly without effort or awareness. Here, the authors report 4 experiments that use a triplet-learning task (TLT) to investigate sequence…

The buffer model proposed by Atkinson and Shiffrin gives a valid measure of primary-memory capacity (i.e., the estimate is close to the true value), a property lacking in both the original Waugh and Norman method and Watkins' modifications of that method. (Author/PN)

Investigated the seriation ability of two groups of four-year-old children with differing levels of language functioning. Results indicated that subjects with delayed language development demonstrated a severe delay in seriation ability, while subjects with normally developing language demonstrated seriation ability commensurate with their…

Nonhuman animals, like humans, appear sensitive to the structure of the elements of sequences, perhaps even when the structure relates nonadjacent elements. In the present study, we examined the contribution of chunking, rule learning, and item memory when rats learned serial patterns composed of two interleaved subpatterns. In one group, the…

An experiment on sequence procedures for presenting text materials to pupils demonstrated that web sequencing (presenting concepts as related parts of a network) resulted in better test performance than linear sequencing. Information processing strategies used by pupils did not influence either the sequence of information presentation or test…

Two studies assessed the effects of material incentives and feedback on the use of rehearsal by first grade children. Subjects were required to remember the order in which the experimenter pointed to simple objects and rehearsal was assessed by observing lip movements during a 15-second retention interval.

Two experiments, one with congenitally deaf and one with hearing individuals, investigated memory for serial order via Cued Speech (CS). Deaf individuals, but not hearing individuals experienced with CS, appeared to use the phonology of CS to support their recall. The recency effect was greater for hearing individuals provided with sound than for…

Background: In the last few years, experimental data have been reported on differences in implicit memory processes of genetically distinct groups of individuals with Intellectual Disability (ID). These evidences are relevant for the more general debate on supposed asynchrony of cognitive maturation in children with abnormal brain development.…

In two experiments, the ability of children younger than 20 months to engage in delayed ordered recall was investigated. In the first experiment, 13- and 16-month-old children were presented with 2-step event sequences and tested for recall, first, immediately following the event and second, after a one-week delay. Sequences were novel-causal,…

Knowledge concerning domain-specific regularities in sequential structure has long been known to affect recall for serial order. However, very little work has been done toward specifying the exact role such knowledge plays. The present article proposes a theory of serial recall in structured domains, based on Bayesian decision theory and a set of…

In a previous study, it was shown that the attentional blink (AB)--the failure to recall the 2nd of 2 visual targets (T1 and T2) presented within 500 ms in rapid serial visual presentation--is reduced when T2 is preceded by a distractor that shares a feature with T2 (e.g., color; Nieuwenstein, Chun, van der Lubbe & Hooge, 2005). Here, this cuing…

A study of the acquisition of time-related grammatical forms in Hebrew-speaking children looked at three kinds of information: (1) relative frequency of occurrence of different verb forms at different ages; (2) the relationship between tense-marking on verbs and the semantics of verbs used at different ages, and (3) the use of time adverbs…

This study examined the effect of presentation rate on accuracy of digit serial recall and on serial position curves of digit strings of different lengths with 18 boys classified as reading retarded and a comparison group of children (ages for both groups averaged 11 years) who read at grade level. The results indicated that normal children…
