Everyday action in the world requires the coordination of "where," "when," and "how" with "what." In late infancy, there appear to be changes in how these different streams of information are integrated into the sequential organization of action. An experiment with 12-, 15-, and 18-month-olds was conducted in order to determine the influence of object properties and locations on the sequential selection of targets for reaching. The results reveal a developmental trend from reach decisions' being influenced only by the spatial layout of locations to the overall pattern of reaching's being influenced by the global configuration of object properties to object properties' influencing the sequential decision of what to reach to next. This trend is a new finding regarding the development of goal-directed action in late infancy.
