Peer reviewedNakayama, Susan Y.; Kee, Daniel W. – Journal of Educational Psychology, 1980
Proactive interference (PI) build-up and release from PI were used to study automatic conceptual encoding of superordinate and subordinate category lists in low-socioeconomic status (SES) Black children and middle-SES White children (grades 2 and 4). (Results for each population on the three category lists are described). (GDC)

Peer reviewedWatson, Catherine; Willows, Dale M. – Journal of Learning Disabilities, 1995
This study investigated specific processing strengths and weaknesses among 75 readers, ages 6-10, with no oral language deficits. Unsuccessful readers of different ages showed similar information processing patterns, and differed from successful first-grade readers on short-term auditory/working memory and decoding/encoding. Three potential…

Peer reviewedHayes, Brett K.; Taplin, John E. – Journal of Experimental Child Psychology, 1992
For both 6 and 11 year olds, social knowledge had a significant influence on test phase responses. It is maintained that the study clarifies the relationship between the use of knowledge-based and similarity-based information in children's acquisition of concepts. (BG)

Peer reviewedFinkelhor, David; Dziuba-Leatherman, Jennifer – American Psychologist, 1994
Outlines a general theory of childhood victimology, with a typology that characterizes abuse as extraordinary, acute, or pandemic. Efforts to prevent childhood victimization must recognize its differential character and the importance of the child's stage of development in recognizing and dealing with victimization. (SLD)

Peer reviewedJohnson, Kathy E.; Scott, Paul; Mervis, Carolyn B. – Developmental Psychology, 1997
Four studies examined developmental differences in the representation of basic-subordinate inclusion relationships in three-, five-, and seven-year olds and undergraduates. Found that even three-year olds showed rudimentary knowledge of the asymmetry of inclusion. There was a marked developmental gap between producing subordinate category names…

Vartuli, Sue; Bolz, Carol; Choi, Dong Hwa – NHSA Dialog, 2004
The primary objective of this research was to determine if 3 methods of assigning sociometric categories contribute similar information. The participants for this investigation consisted of 72 Headstart children from 3 classrooms. The results of this research indicate that social status categories based on peer ratings and nominations could be…

Dembo, Richard; Schmeidler, James; Childs, Kristina – Journal of Child Sexual Abuse, 2007
This paper reports the results of developing and evaluating a classification of 315 arrested youth processed at the Hillsborough County Juvenile Assessment Center from September 1, 1994 to January 31, 1998. Youth were characterized as physically or sexually abused if they reported abuse or if they had been referred to juvenile court for abuse.…

Schneider, Wolfgang – 1985
The present study investigated the relationship between developmental shifts in the organization of materials and developmental changes in deliberate strategy use. Second- and fourth-grade children were presented with clusterable sort/recall lists representing the factorial combinations of high and low inter-item association and high and low…

Teske, John A.; Laird, James D. – 1981
During socialization, individuals begin to understand increasingly broader and more abstract units of personal and social reality. Subjects (N=97) ranging in age from 13 to late middle age completed a linguistic task in which they could impose higher order conceptions on lower order descriptions by identifying different level similarities within…

O'Hara, Takeshi; And Others – 1978
Path analysis was used to reanalyze Kropp and Stoker's data from tests designed to evaluate Bloom's taxonomy of educational objectives in the cognitive domain. Scores for 1,128 students in grades nine through twelve were analyzed separately by grade level for four content areas on six taxonomic levels. A measure of general ability was also…

The Effects of Selected Experiences on the Classification and Seriation Abilities of Young Children.
Johnson, Martin L.
The purposes of this study were to: (1) determine the influence of a series of experiences involving the equivalence relation "same length as" and the asymmetric transitive relations "longer than" and "shorter than" on the ability of first and second grade children to classify and seriate objects on the basis of length; (2) investigate the…

Peer reviewedSulzby, Elizabeth – Reading Research Quarterly, 1985
Emergent reading attempts of 24 children at the beginning of their kindergarten year are content analyzed in light of theoretical considerations about general and language development. In addition, the reading attempts of two-, three-, and four-year olds are examined. Comparison of data reveal a developmental progress across age-levels. (HOD)

Peer reviewedEnns, James T.; King, Katherine A. – Developmental Psychology, 1990
Experiment 1 suggested that age differences in line-drawing interpretation among subjects between 6 and 24 years reflected changes in short-term memory for features and changes in strategies used to integrate features over space and time. Experiment 2 suggested that older observers were more active in their attempts to interpret drawings and that…

Peer reviewedWard, Thomas B.; And Others – Child Development, 1989
Studied the way in which 32 preschoolers aged three-five years, 28 second-graders and 64 undergraduates generalized from a labeled exemplar to other potential members of the same category. Results indicated that preschoolers focused mostly on single attributes in making category decisions and older individuals primarily exhibited multiple…

Peer reviewedAckerman, Peggy T.; And Others – Learning Disabilities Research and Practice, 1992
Forty children (ages 9-12) identified as having dyslexia on the basis of intelligence and achievement tests were evaluated. Results imply that a test of phonological sensitivity and another of nonsense word decoding identified children who were dysphonetic. Nondysphonetic disabled readers were older and had higher verbal intelligence quotients…
