Although human infants demonstrate early competence to retain visual information, memory capacities during infancy remain largely undocumented. In three experiments, we used a Visual Paired Comparison (VPC) task to examine abilities to encode identity (Experiment 1) and spatial properties (Experiments 2a and 2b) of unfamiliar complex visual…

It has been suggested that older adults are more variable in their performance because they are more prone to lapses of either attention or intention. In the present experiment, 9 young and 9 older adults each performed nearly 2,000 trials of a same-different judgment task. As expected, older adults were slower and more variable than young adults.…

This paper questions the assumption that a central processing deficit exists in the speed of performing mental operations by children as compared to adults. Two hypotheses are proposed and data are cited as evidence. (JMB)

This report describes a series of studies concerned with preschool children's art. Preliminary work was based on observation of sessions in which one child would draw a picture in the presence of an adult. Major findings were that: (1) the children did not have preconceived notions of what they would draw; (2) they did not try to capture a moment…

The study paired-associate (PA) learning via the anticipation (ANT) and study-test (ST) procedures across second, third, fourth and fifth grades. Specifically, age differences in the rate of learning and examining PA learning according to the stage analyses were examined. Retention was also of interest: however, a ceiling effect negated the…

It is argued that wheather the course of cognitive development is characterized by growth, stability, or decline is less a matter of the metamodel on which the theories and data are based. Such metamodels are representations of reality that are not empirically testable. (Author)

In two experiments, first and fourth grade subjects performed a speeded card sorting task with either integral or nonintegral dimensions. The dimensions were arranged so that subjects sorted on three types of task: (1) single dimension, (2) correlated dimensions, and (3) orthogonal dimensions. (Author/MS)
