The pattern separation task has recently emerged as a behavioral model of hippocampus function and has been used in several pharmaceutical trials. The canine is a useful model to evaluate a multitude of hippocampal-dependent cognitive tasks that parallel those in humans. Thus, this study was designed to evaluate the suitability of pattern…

Individuals of all ages extract structure from the sequences of patterns they encounter in their environment, an ability that is at the very heart of cognition. Exactly what underlies this ability has been the subject of much debate over the years. A novel mechanism, implicit chunk recognition (ICR), is proposed for sequence segmentation and chunk…

Basic brain function is not a mystery. Given that neuroscientists understand the brain's basic functioning processes, one wonders what their research suggests to teachers of developmental algebra. What if we knew how to teach so as to improve understanding of the algebra taught to developmental algebra students? What if we knew how the brain…

Purpose: This study investigated the relationship between hearing loss and memory and attention when nonverbal, visually presented cognitive tests are used. Method: Hearing loss (pure-tone audiometry) and IQ were measured in 30 participants with mild to severe hearing loss. Participants performed cognitive tests of pattern recognition memory,…

In discussing the relationship between cognitive development (perception, pattern recognition, and memory) and reading processes, this paper especially emphasizes developmental factors. After an overview of some issues that bear on how written language is processed, the paper presents a discussion of pattern recognition, including general pattern…

A study is reported in which subjects were shown sentences, some of which they had read previously, after intervals ranging from a few minutes to 32 days. Results show that information about typography can be recovered for at least 32 days after initial reading. Implications are discussed. (Author/RM)

The relative importance of spatial-position as a memory aid in a block pattern reproduction task was investigated by analyzing the object-selection and object-placement strategies of 69 nursery school children. Subjects were given a task modeled on Piaget's assessment of Static Reproductive Images and Action that had been modified into a…

Two strings of letters were presented. Subjects were instructed to indicate whether the second string contained the same elements as the first, regardless of position. Reaction time increased with the number of positions that the letters were displaced. Results indicate that order may be an important factor in retrieval from memory. (Author/BW)

Reviews recent progress in modeling human cognition, in particular the use of computers in generating models. Topics covered include the information processing approach to cognition, problem solving, semantic memory, pattern induction, and learning and cognitive development. A 164-item reference list is attached. (JL)

Study was carried out to examine the feasibility of identifying by a short test whether or not any particular profoundly deaf school child uses a speech code in short-term memory for verbal material. (Author)

Three experiments evaluated color specificity knowledge and related semantic effects on recognition memory. (Author/SB)

A set of studies investigated the relative importance of operative schemes and figurative (rote) memory. In Study I, 60 concrete operational children from grades 1-4 were asked to reconstruct two types of stimuli from memory. In order to separate the effects of operative and figurative skill use, learning disabled children with poor figurative…

This paper reports two experiments investigating the effect of schooling and urbanization on short term recall and recognition memory. Subjects were 384 male children and young adults living in Morocco representing urban and rural and schooled and nonschooled backgrounds. Additional subject groups--including Koranic school students, Moroccan rug…

A total of 72 children, 36 each from first and sixth grades, were given a 70-item study list followed by a recognition test list of equal length. To indicate the relative dominance of features encoded at both ages, labels, pictures, and referents were recombined to form visual, semantic and acoustic distractors. (MS)
