Humans perceptually extract quantity information from our environments, be it from simple stimuli in isolation, or from relational magnitudes formed by taking ratios of pairs of simple stimuli. Some have proposed that these two types of magnitude are processed by a common system, whereas others have proposed separate systems. To test these…

This study examined children's use of category information as a discrimination cue to avoid intrusions in recall and false alarms in recognition of items outside given categories. Forty-eight children in grades 1 and 4 were administered one of three conditions of a recognition task in which all study words were members of one of two familiar…

Results indicated the following: unitary stimuli were easier to encode; partitioned stimuli were easier to recode; recoding was much more difficult than encoding; extended training improved performance; second graders were slightly better at encoding and much better at recoding than were kindergarten children.

Cognitive organization in problem solving was investigated using a transfer paradigm. (SB)

This study is designed to test the hypothesis that an inability to separate incoming information into discrete messages is a source of young children's relatively poor performance in selective attention tasks. Subjects were 27 children drawn from kindergarten, second grade and fifth grade classes. (Author/GO)

In this study, hypothesis probe techniques were used to provide trial-to-trial monitoring of second and third grade children's use of feedback. (SB)

A total of 45 fifth grade students were the subjects of an experiment offering support for a component of learning strategy (memory imagery). Various theoretical explanations of the image-tracing phenomenon are considered, including depth of processing, dual coding and frequency. (MS)

The question of how children represent and use comparative or partially ordered information is examined. Two experiments tested a conjecture that a common representation, a linear order, underlies the processing of all comparatives. (Author/MS)

Comparison between relational concepts and word definitions coincided with lower levels of thinking, and abstract definitions with the highest level. (Author)

Forty elementary children (six and nine year olds) and 20 college students were required to discriminate identical pairs of visual stimuli from mirror images. It was hypothesized that a key factor in performance would be the extent to which orientation was a functionally significant attribute of the stimuli. (Author/MP)

Reports on two studies during which 6-, 8-, and 10-year-old children were interviewed about three different types of regularities or rules: social conventions, physical laws, and logical necessities. Shows that older children made more distinctions between social and nonsocial items than did younger children. (HOD)

Second grade Ss and college students were tested under three conditions of the temporal relationship of feedback and stimulus information. (Editor)

This study indicates that impulsive children inhibit expressive behavior less than reflective children in the presence of a nonverbal inhibitory cue, and provides support for the construct validity of the Matching Familiar Figures Test of reflectivity/impulsivity. (GO)

According to Hypothesis (H) theory, learning should be very difficult when the number of Hs the subject samples from is very large and/or the correct H is not available. These assumptions were tested with third- and fourth-grade children. In general, results supported these assumptions. (Author/MP)
