Peer reviewedTomes, Lucrezia; Shelton, Ralph L. – Journal of Speech and Hearing Research, 1989
The ability of 10 normal-speaking 5-year-olds and 10-normal-speaking 7-year-olds to categorize consonants as "dripping" (stop), "flowing" (fricative), "tongue" (lingual place of articulation), "or "lip" (labial place of articulation) was evaluated. Children's ability to categorize was evaluated as an indicator of their awareness of feature…

Peer reviewedDaehler, Marvin W.; Bukatko, Danuta – Child Development, 1974
Discrimination learning studied in 3-year-olds, indicated that children over 30 months of age did better than younger children, and girls learned faster than boys after the first problem. (ST)

Peer reviewedMiller, Dolores J.; And Others – Child Development, 1976
Serial habituation of visual fixations was investigated through a design permitting cross-sectional, within-subject longitudinal, cohort longitudinal, and time-lag analyses. Results suggested that for all ages habituation was under way to the parts of the stimulus in order of the realitive saliencies. No one methodology appeared to significantly…

Odom, Richard D.; Guzman, Richard D. – J Exp Child Psychol, 1970
Age and condition (either constancy-relevant or variability-relevant) interact, with the youngest group in the constancy-relevant condition performing most poorly on concept identification tasks. (MH)

Peer reviewedNovack, Thomas A.; Richman, Charles L. – Child Development, 1980
Tests the effects of stimulus variability on overgeneralization and overdiscrimination errors in children and adults. The subjects (n=64), adults and five-, seven-, and nine-year-old children, participated in a visual discrimination task. (CM)

Peer reviewedSpiker, Charles C.; Cantor, Joan H. – Journal of Experimental Child Psychology, 1980
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.

Peer reviewedMareschal, Denis; Powell, Daisy; Volein, Agnes – Journal of Experimental Child Psychology, 2003
Examined 7- and 9-month-olds' ability to categorize cats and dogs as separate from one another. Found that both groups formed a cat category that included novel cats but excluded a dog and an eagle, and formed a dog category that included novel dogs and a novel cat but excluded an eagle. Results mirrored those of 3- to 4-month-olds with visual…

Peer reviewedCranford, Jerry L.; And Others – Journal of Speech and Hearing Research, 1993
This study evaluated the ability of 30 normally developing children (ages 6-12) to report the perceived location of a stationary fused auditory image (FAI) or track a "moving" FAI. Although subjects performed at normal adult levels with the stationary sound measure, they exhibited a significant age-related trend with the moving sound…

This study investigated the way 12 infants, aged 1 month and 2 months, scanned the still and expressionless faces of their mothers, of strange women, and of strange men. Each infant was placed in a padded head-restraining cradle under a half-silvered mirror which was angled at 45 degrees to enable the child to view an adult's face at an optical…

Miller, Frank D.; Moffat, Gene H. – 1970
A major concern of this report was to compare the effect of three verbal reinforcement combinations (VRCs) on the rate at which children learn a simultaneous two-choice discrimination problem. The experiments were designed to test the following: (1) whether relative effectiveness of the VRCs was dependent upon task complexity or subject age; (2)…

Peer reviewedCherry, Rochelle Silberzweig – Perceptual and Motor Skills, 1981
Fifty-three children (ages 5-9) were individually tested on their ability to select pictures of monosyllabic words presented diotically via headphones. Tasks were presented in quiet and under three noise (distractor) conditions: white noise, speech backwards, and speech forward. Age and type of distractor significantly influenced test scores.…
