A developmentally sensitive problem-solving task--the 20-Question Game--was used to examine development and treatment variables among 48 learning disabled and 48 normal boys at two age levels (8-13 years old). Results indicate that both younger boys and learning disabled boys demonstrated less efficient problem-solving skills than did others. (TJH)

The promise of joking riddles as a developmental index of children's humor was investigated through studying the enjoyment and comprehension of riddles and nonriddles by first-, third-, and fifth-grade normal children. Based on previous studies, it was predicted that enjoyment and comprehension of riddles would increase with age and that the…

Birth order effects on intellectual performance show both positive and negative results. Considers the intellectual aspects of siblings' changing environments, explaining that birth order and family size effects depend crucially on the age at which children are tested.

Piaget, in describing the sequence of classificatory development, describes class inclusion as composed of two processes; hierarchical classification and post-whole comparisons. In the experiment reported here, elementary school children, trained in the concept of sets in first grade mathematics were given a task where they were required to assess…

Confirmatory factor analysis of data from a portion of a long-term study provided evidence for two components of math anxiety for 298 male and 266 female 6th through 12th graders. The components related to negative affective reactions and cognitive aspects. Age and gender differences were significant. (TJH)
