Dissimilarity judgments of all possible pairs of 10 animal names were obtained from first-, third-, and sixth-grade children, and college students. Analysis with multidimensional scaling procedures revealed a semantic space consisting of the features of size, domesticity, and predativity. (Author/JMB)

Two experiments were conducted to examine developmental changes from middle childhood to adolescence in metaretrieval plans offered to solve different retrieval problems. (Author/JMB)

In a combined verbal and motor paired-associate task, children in kindergarten, second grade, and fourth grade learned nonsense names and spatial responses for three random shapes. Results showed evidence for mediation at all three age levels and increased mediational effects with age. (Author/JMB)

Examined the relationship of ability to conserve and comprehend of logical riddles in 33 first-, third- and fifth-grade boys of average intelligence. Although both riddle comprehension and cognitive maturity as assessed by Piagetian tasks increased with grade, the relation between them was not clearly demonstrated. (Author/JMB)

The relation between conceptual development and visual exploratory behavior was investigated by engaging eighty-four 3-, 4-, and 8-year-old children in a picture-sorting task to determine whether they would spontaneously and readily discriminate between animate and inanimate objects. (Author/JMB)

Three experiments examined elementary school children's ascriptions of blame for communication failure in a game in which either the child or the experimenter described one of a set of drawings so that the other could pick the matching one from an identical set. (Author/JMB)
