Second-grade children, third-grade children, and adults judged whether pictures were members of a positive or negative memory set while trying to ignore irrelevant words printed inside the pictures. (JMB)

Investigated the relation between infant expectations and reaction time (RT) at age 3 months, and Childhood IQ and RT at 4 years. Found that visual RT and manual RT in childhood correlated only marginally. Data suggested stability in RT between early infancy and childhood, or predictability of childhood IQ by infant RT and anticipation during…

Speculates on underlying processes for the reaction time variance and age differences in anticipation latency using the Visual Expectation Paradigm. Discusses the dichotomization of reactive and anticipatory behavior, limitations of longitudinal designs, drawbacks in using standard procedures and materials, and inferences that can be made…

As part of a study to determine whether visual and manual response systems are correlated, 26 children between 40 and 51 months of age took part in visual and manual reaction time (RT) tasks. Subjects, whose RTs had previously been tested at 3 months of age, were tested in 1 of 2 conditions. In the first condition, subjects viewed pictures only…
