Brief Summary:
This study is concerned with psychological and physiological development in infants Specifically researchers are interested in when and how babies are able to group similar objects like animals or vehicles into the same category This study will investigate whether motion aids in the categorization process and allows for earlier demonstration of this competency
Previous studies have demonstrated that the ability to categorize stationary objects or images of objects is present by 6 months of age This study is made up of three experiments to test
1 The infants ability to categorize photographic stimuli
2 The infants ability to categorize moving stimuli
3 The infants ability to transfer knowledge from moving to photographic stimuli
Initially the abilities of 3- and 6-month-old infants will be compared It is also possible that 9-month-old infants will be tested Data will consist of looking at time measures level of attention to displays and heart rate The ability of infants to transfer category knowledge will support the view that motion is a source of information for object categorization

Detailed Description:
The major objective of this research is to better understand the early development of perceptual categorization The proposed work is designed to examine the emergence of infants ability to access internal categorical representations Representation refers simply to stored information that can influence later behavior Categorization refers to the treatment of discriminable objects as equivalent in some way Even very young infants appear able to visually categorize diverse sets of discriminable patterns or objects Much less is known however about how infants internally represent and utilize such information The present set of studies is designed to probe the ontogeny of category of representations in infancy The methodological strategy to be used in the first study consists of exposing infants to entirely novel configurations of objects for fixed amounts of time and later analyzing infants examination and manipulation of those objects once they have become familiar Infants will be exposed to these novel categories of objects at home over a 2-month period Later in a laboratory procedure 5-month-old infants will be tested both with the familiar objects and similar test objects A second study will utilize eye-tracking technology to examine the nature of infants eye movements as they visually encode the individual members of complex categories such as animals and vehicles Finally a third study is being conducted to examine the relation between individual differences in infants category learning and subsequent variability in language learning later on in childhood
