This research investigated whether symbolic understanding of pictures in low-functioning children with autism is mediated by iconicity and language. In Experiment 1, participants were taught novel words paired with unfamiliar pictures that varied in iconicity (black-and-white line drawings, greyscale photographs, colour line drawings, colour…

Reports and surveys by the U.S. government and international organizations have repeatedly acknowledged the achievement problem in math in K-12 regardless of various efforts (e.g., by the U.S. Department of Education) to diminish it. To address the problem in math achievement in K-12, teachers, scholars, and the U.S. government have developed…

Two studies examined the progress in normally developing preschoolers' ability to produce actions with imagined objects (pantomimes). Found that young children not only had difficulty producing imaginary object representations in contrast to normal adults, they also had difficulty comprehending imaginary object representations and were better at…

Piaget's concept of "internalization" is analyzed and related to Bruner's representational theories of cognitive development. Cognitive structures are shown to be real exclusively in an actual representation. (Author/SDH)

Infants were exposed to symbolic gestures from their parents beginning at 11 months of age. In bimonthly interviews, mothers reported their infants' use of gestures and words. Results indicated a smaller but reliable difference between the onset of infants' use of symbolic gesture and the onset of their use of words than earlier research…

Examined whether toddlers would use information presented through video to solve a retrieval problem. Found that 2.5-year-olds were very successful at finding a hidden toy based on viewing a televised hiding event, but 2-year-olds were not. Substantially better performance was achieved by other 2-year-olds who either watched or believed they were…

In an early education program, 100 disadvantaged 4-year-olds (50 Negroes and 50 whites) attend classes one-half day, four days a week, from October through June. A teacher visits each child's home every other week to conduct a tutorial session lasting 1 1/2 hours. Three objectives of the program are (1) to develop a preschool curriculum based on…

Children's communication performance improves with age, which could result from increases in children's vocabularies, changes in their strategies of selecting messages from their vocabularies, or both. Three experiments were conducted to evaluate these explanations. Two types of communication tasks were employed. These data suggest younger…

Examines the differential influence of pictorial vs. verbal forms on the comprehension of metaphor in younger (second grade) and older (fifth grade) children through their performance on the pictorial Metaphoric Triads Task. (HOD)

This study was conducted to determine whether the filmic coding elements of split screen, slow motion, generated line cues, the zoom of a camera, and rotation could aid in the development of the Euclidean space concepts of horizontality and verticality, and to explore presence and development of spatial skills involving these two concepts in…

Investigates two questions: (1) the sex-related differences in Landsat Mastery, road map reading, and map drawing among adolescents and (2) the relationship between spatial ability and mapping skills. Replicates significantly lower female performance on parts of the Landsat tasks. Concludes that spatial ability correlations with mapping are too…

The drivers in a battalion about to be deployed to Germany were taught the meanings of international road signs using one of the following techniques: Sign Only, in which the road signs were presented via a slide projector and the names of the slides provided orally by the instructor; Sign Elaboration, which was identical to the Sign Only…
