Demonstrated that six-year-olds performed as well as 17-year-olds in discriminating self-generated memories from memories that were the result of external presentation. However, six-year-olds were not as adept as nine-year-olds in discriminating what they had said earlier from what they had only thought. (Author/MP)

Experiment I establishes that the ability to remember the slope of a line develops between three and four years of age. In Experiment II, 15 children with a mean age of four years and six months who had discriminated both slope and left-right problems under successive presentation were tested on these same discriminations under simultaneous…

Two experiments examined hyperactive children's tendency to underfocus their attention during learning. Taken together, the results of both experiments demonstrated the validity of the attentional diffusion hypothesis and indicate the need to assess the central processing demands associated with central and incidental learning in order to evaluate…

In the first experiment, 16 kindergarten children were tested on vertical/horizontal and oblique discriminations in symmetrical and asymmetrical alignments. When stimuli were asymmetrically aligned, the former discrimination was learned as rapidly as the latter. The second experiment demonstrated that the influence of configurational cues in…

Visual and auditory processing of complex sentences was examined among 8- through 11-year-olds. Findings suggested a U-shaped learning pattern for on-line processing of restrictive relative clauses. Off-line accuracy scores showed different patterns for good and poor comprehenders. Incorrect local attachment strategy use was related to sentence…
