Children made age judgments on drawing of human figures, which consisted of adult, adolescent, child, and infant characterizations. (Author)

Presents a study which assessed preschool children's understanding of "front,""back," and "side" through a variety of tasks. A developmental sequence is defined. (ED)

Kindergarten through fourth graders (N=170) were tested for conservation and then interviewed following the presentation of a story about an elderly woman's death, in an attempt to assess children's understanding of 3 concepts: irrevocability, cessation of bodily processes, and universality. (Author/JMB)

A multivariate modification of the cross-lagged panel correlation paradigm was applied to data from 4 subgroups of students tested and retested in fifth, seventh, ninth, and eleventh grades on 16 essentially identical cognitive measures. Results suggested that the test of aural comprehension was tapping the causal factors involved in intellectual…

It was concluded that while retinoblastoma per se is not associated with intellectual superiority or inferiority, retinoblastoma associated with blindness may result in selective cognitive superiority. (Authors)

Nine tasks were designed to test the developmental sequence of three types of "because" (affective, physical, concrete logical) in 100 children aged 3 to 7 years. The tasks tested whether comprehension of "because" preceded its usage and at what point children understood that sentences with reversed clauses were incorrect.…

Estimates confluence model of intellectual development for a within-family sample of 321 children from 101 transracial adoptive families. Mental ages of children and their parents and birth or adoption intervals were used in a nonlinear least-squares estimation procedure to obtain children's predicted mental ages. Results suggest efficiency of the…

Explains that from a prediction standpoint the confluence model is not very efficient. Very modest increments in accuracy are associated with family configuration variables once chronological age is covaried. Suggests that the major postulates of the theory be tested directly, within individuals and with longitudinal data. (Author/AS)

The study investigated the communicative effectiveness of word order in preschoolers' comprehension of meaning using simple questions and commands in an at-home play context. (ST)

Intellectual realism was investigated by using as a model a cup with the defining feature (the handle) not visible, and a nondefining feature (a painted flower) visible. (Authors/MB)

Normal, first-born children of two-parent, self-supporting families (N=60) were divided into three groups at birth: control, mothers receiving a specific language stimulation program, and both parents receiving the program simultaneously. Infants whose parents received simultaneous training exhibited the greatest gain over 4 1/2 months in Bayley…

Examined the origins of high general cognitive ability (g) in twins who were participating in the MacArthur Longitudinal Twin Study. Formed high g groups from the 19th percentile and above at each age. Results suggested increasing genetic influence and increasing genetic stability from 14 to 36 months and substantial genetic influences with…

Children's ability to infer consequences from sentences automatically was assessed in two cued recall experiments. Seven- and eight-year-old children and adults served as subjects. (JMB)
