Lessons for first-grade students deal with the numbers five and six. How groups of five and six differ is the focus of the comparing and counting activities. (MNS)

A student noticed an interesting fact about the base two numerals for perfect numbers. Mathematical explanations for some questions are given. (MNS)

Three experiments were conducted to examine whether infants can detect the color of stationary and moving objects and maintain this discrimination over change in velocity. Subjects were 80 infants ages 8 to 20 weeks. (MP)

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

Elementary School Teachers were instructed on finding number patterns in a figure in one of three groups: individual discovery, group discovery, and expository. They were tested for recall, retention, and transfer. The expository groups did better on recall, but group discovery was more effective for retention and recall. (SD)

This study, using the Visual Pattern Recognition Test for Prereading Skills, found that beginning readers improve in word recognition if they are given training in identifying essential components of letters. (HOD)

A study investigated the accuracy and speed of face recognition in 26 children (ages 7-10) with Pervasive Developmental Disorder Not Otherwise Specified. Subjects needed an amount of time to recognize the faces that almost equaled the time they needed to recognize abstract patterns that were difficult to distinguish. (Contains references.)…

Described are a discrete group of isometries that fix a line but do not stabilize a point. Each type is accompanied by an example of their representation in concrete form which served as material on which young children could operate. Pupil responses to each situation are provided. (CW)

Describes activities for developing pattern recognition and classification using worksheets. The objectives, directions, extensions, and bibliography are provided for each activity. (YP)

Preschool, kindergarten, and first-grade Brazilian children who performed well on an easy rhyme-categorization task were given a second such task that seemed to require some analytical ability to perform successfully. Results suggest that children's rhyme detection does not involve attention to word segments but a sensitivity to some sort of…

Several models of information integration are developed and analyzed in the context of a prototypical pattern-recognition task. Evaluation, integration, and decision-making processes are specified for each. Simulations and predictions are carried out to provide a measure of identifiability or extent to which they can be distinguished from one…

Artificial neural networks (ANN), part of artificial intelligence, are discussed. Such networks are fed sample cases (training sets), learn how to recognize patterns in the sample data, and use this experience in handling new cases. Two cognitive roles for ANNs (intelligent filters and spreading, associative memories) are examined. Prototypes…

Discusses that Gestalt principles are especially well suited to teaching music. Identifies the laws of proximity, similarity, common direction, and simplicity in the notation system. Suggests that music teachers use these principles by following a logical progression to teach students to improve musical skills, solve problems, and think in…

Presents responses to the pattern problem that appeared in the November 1998 "Problem Solvers" section of this journal. (ASK)
