Peer reviewedWentworth, Naomi; Haith, Marshall M. – Developmental Psychology, 1992
A modified Visual Expectation Paradigm assessed the role of picture content in the spatiotemporal expectations of 80 infants. Stable picture content information facilitated formation of expectations about when and where pictures would appear. Two month olds' reactions were consistently slower than those of three month olds.(LB)

Peer reviewedCasey, M. Beth – Developmental Psychology, 1984
Evaluates preschoolers' ability to distinguish left-right mirror-images of objects on a memory task and ability to name rows of objects on a page in a consistent lateral direction. Abilities were assessed first without specific instructions on the relevance of left-right information and then with instructions. (Author/AS)

Peer reviewedEnns, James T.; Girgus, Joan S. – Developmental Psychology, 1986
Three experiments with observers aged 6 to 21 years of age examined the integration of shape information over successive glances. Results indicated age-related improvements in the sequential integration of shape information, both when integration occurs through successive glimpses over space and when information is separated only in time.

Peer reviewedCanfield, Richard L.; Haith, Marshall M. – Developmental Psychology, 1991
Infants' visual fixations were monitored while they viewed predictable and unpredictable sequences of stimuli. Analyses of anticipatory fixations indicated that by two months of age, infants form expectations for the reappearance of visual stimuli positioned opposite to each other. By three months, infants rapidly form expectations for asymmetric…

It was shown that hierarchies change with development and that relative salience of a dimension is negatively associated with both reaction time of choice and number of errors on the identity task. (Authors)

Tested three competing structural equation models concerning auditory inspection time (AIT) and cognitive ability. Found that auditory inspection times near age 11 correlate most strongly with later high IQ. (ET)

Peer reviewedKail, Robert – Developmental Psychology, 1991
Children and adults were tested on six speeded perceptual-motor and cognitive tasks, including a (1) response time task; (2) button tapping task; (3) pegboard task; (4) coding task; (5) picture matching task; and (6) mental addition task. Age-related change in processing time on most of these tasks was described by a single exponential function.…
