Investigates whether elementary school children can successfully execute a mental rotation on Marmor's state-comparison task without knowledge of logical sequence relations, whereas such knowledge is required to construct or evaluate external representations of the successive states in a rotation movement.

Eight-year-old children were trained on length or weight relationships between adjacent members of a five-item series of colored objects. Visual feedback was provided. Results indicated more salient visual feedback reduced learning effort for length but not for weight comparisons. Encoding differences found in another experiment were used to…

To examine developmental aspects of auditory sensory memory, a series of experiments was conducted on the stimulus suffix effect with the primary variables being age of subject (7 and 11 years), rates of presentation, and length of list. Effects were nearly identical across age groups when a fast presentation rate was used. (Author/DB)
