Long-term semantic memory (LTM) is known for affecting recall during working memory (WM) tasks. However, the way LTM intervenes in WM remains unknown. Moreover, the available findings are incongruent concerning how attention modulates the impact of LTM on WM. To examine this issue, the involvement of LTM representations in a complex span task was…

Discusses Needham's findings that infants individuate objects by feature, within the framework of brain mechanisms that index or track individual objects, drawing upon theories of attention and working memory developed in the study of adults. Considers Needham's work as contributing to an understanding of categorization and the effect of object…

Argues for an informational processing explanation for young infants' ability to use featural cues to differentiate objects, centering on the development of infants' ability to integrate both featural and object information. Considers information processing propositions and evidence on object segregation. (JPB)

Discusses connections between infants' use of object knowledge in recognition to computational, psychophysical, and neurophysiological research on adult perceptual segmentation and grouping. Considers these connections through a framework of the tasks and information involved in adult object segregation, and interprets Needham's results in this…

Discusses responses to Needham's research on infants' use of featural, physical and experiential information to segregate displays. Considers characterization of different kinds of information infants use when segregating objects. Discusses relations between processes underlying object segregation. Considers the roles of visual versus linguistic…
