This review summarizes a series of experiments aimed at answering the question whether the hippocampus in rats can serve as an animal model of amnesia. It is recognized that a comparison of the functions of the rat hippocampus with human hippocampus is difficult, because of differences in methodology, differences in complexity of life experiences,…

The current study examined the contribution of brain areas affected by Parkinson's disease (PD) to sequence learning, with a specific focus on response-related processes, spatial attentional control, and executive functioning. Patients with mild PD, patients with moderate PD, and healthy age-matched participants performed three tasks--a sequence…

Conceptual knowledge of our world is represented in semantic memory in terms of concepts and semantic relations between concepts. We used functional magnetic resonance imaging (fMRI) to examine the cortical regions underlying the processing of sequential and taxonomic relations. Participants were presented verbal cues and performed three tasks:…

Research on incidental sequence learning typically is concerned with the characteristics of implicit or nonconscious learning. In this article, the authors aim to elucidate the cognitive mechanisms that contribute to the generation of explicit, reportable sequence knowledge. According to the unexpected-event hypothesis (P. A. Frensch, H. Haider,…

In a serial recall task, the "Hebb repetition effect" occurs when recall performance improves for a sequence repeated throughout the experimental session. This phenomenon has been replicated many times. Nevertheless, such cumulative learning seldom leads to perfect recall of the whole sequence, and errors persist. Here the authors report…

Word-retrieval and rapid naming abilities play an important role in language processing and cognitive development. Researchers have demonstrated that early language difficulties may lead to later reading impairments and several decades of research has convincingly demonstrated that rapid automatized naming is a powerful predictor of concurrent and…

Two studies, an experimental category learning task and a computational simulation, examined how sequencing training instances to maximize comparison and memory affects category learning. In Study 1, 2-year-old children learned color categories with three training conditions that varied in how categories were distributed throughout training and…

This paper presents a temporal sequence memory based on the circuit configuration of the dentate gyrus of the mammalian hippocampus. (Author)

Data indicate that the Visual-Sequential Memory subtest of the ITPA and the Knox Cube Test measure different aspects of visual-sequential memory ability. (KW)

The study used the semantic strategy of stories linking to-be-remembered items and a serial-recall requirement with 27 educable mentally retarded adolescents. In comparison to control subjects, Ss recalled more in the early trials of original learning, but retention after eight months was comparable for the two conditions. (Author/DB)

Daily practice for 15-20 minutes of repeating series of numbers resulted in improvement in auditory, sequential memory for five 13-year-olds with moderate learning difficulties. Subjects in the control and placebo group also demonstrated progress. Experimental Subjects demonstrated greater increases over a two-year period. (CL)

The production of complex sequences like music or speech requires the rapid and temporally precise production of events (e.g., notes and chords), often at fast rates. Memory retrieval in these circumstances may rely on the simultaneous activation of both the current event and the surrounding context (Lashley, 1951). We describe an extension to a…

Contrasts sequential and relational processing manipulations of passages with manipulations which focus on individual lexical items and the propositions in which they are embedded. Finds recall to be superior when readers use sequential and relational processing during performance of individual item-specific lexical processing. (RS)
