Peer reviewedBahrick, Lorraine E.; Gogate, Lakshmi J.; Ruiz, Ivonne – Child Development, 2002
Three experiments investigated discrimination and memory of 5.5-month-olds for videotapes of women performing different activities (blowing bubbles, brushing hair, brushing teeth) or static displays after a 1-minute and a 7-week delay. Findings demonstrate the attentional salience of actions over faces in dynamic events to 5.5-month-olds. Findings…

Peer reviewedTan, Lynne S. C.; Bryant, Peter – Child Development, 2000
Used shift-rate recovery method in three experiments to examine extent to which 6-month-olds find perceptual cues such as density and length useful in discrimination of linearly arranged sets of large numbers of objects. Found that infants can discriminate between large number sets by relying on absolute cues such as density and on relative cues…

Peer reviewedKnight, Carol A.; Scholnick, Ellin Kofsky – Child Development, 1973
Groups trained to compare the whole and subset improved in cue identification from negative instances; performance in the stimulus exposure group declined. (Authors)

Peer reviewedKamil, Michael L.; Rudegeair, Robert E. – Child Development, 1972
Two major implications of this study are that repeated testing is a necessity for young children, and that repeated contrasts may provide a more accurate assessment of phonological discrimination ability in children. (Authors/MB)

Peer reviewedMelnick, Gerald I. – Child Development, 1973
An extension of discrimination-learning theory based on the inhibition of stimulus intensity was proposed and supported as a mechanism of cognitive development. Among 48 normal and 37 educable mentally retarded children the predominant category of transistional children conserved at a low level of stimulus intensity but failed to conserve at a…

Peer reviewedSwartz, Karyl; Hall, Alfred E. – Child Development, 1972
Comparison between relational concepts and word definitions coincided with lower levels of thinking, and abstract definitions with the highest level. (Author)

Peer reviewedLonghurst, Thomas M.; Turnure, James E. – Child Development, 1971
Investigation indicates that perceptual inadequacy must be controlled in studies that utilize ambiguous, novel or nonsense designs in stimulus materials. (Authors)

Peer reviewedPauen, Sabina – Child Development, 2002
Two studies examined whether infants' category discrimination in an object-examination task was based solely on an ad hoc analysis of perceptual similarities among the experimental stimuli. Findings indicated that 10- to 11-month- olds' responses varied systematically only with the presence of a category change, but not with the degree of…

Peer reviewedKomatsu, Lloyd K.; Galotti, Kathleen M. – Child Development, 1986
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)

Peer reviewedParis, Scott G.; Cairns, Robert B. – Child Development, 1972
Research combined an experimental analysis of the cue properties of evaluative comments with a naturalistic account of the functions that such events serve in everyday interchanges. (Authors)
