Brief Summary: This study will explore how babies become able to use their experience with objects to plan to manipulate them appropriately For example an adult knows that picking up a grocery bag full of canned food requires different actions than are needed for lifting an empty bag This study will examine when and how infants first begin to adapt their actions to manipulate specific objects that weigh different amounts

Participants will include normal healthy babies within 2 weeks of their first birthday If the expected results are obtained from testing 9-month-old children will then be studied to identify a lower age boundary in task performance If the expected results are not obtained at the 12-month test age older children will be recruited to participate

The study involves one 30-minute session with the baby and his or her mother or father The parent will answer some questions about the family such as its size and ethnic make-up The infant will then have small magnetic sensors taped to the underside of each arm and to the back While sitting on the parent s lap the infant will be presented with plastic toys and his or her actions will be measured by the sensors as he or she reaches for and picks up the toys The sensors will be connected to a computer that will track and record the motion of the infant s arms

Detailed Description: The major objective of this research is to better understand the functional significance of object categorization in early development The proposed work is designed to examine the emergence of infants ability to access internal categorical representations in service of planning actions on the external environment Representation in this capacity 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 and can form internal representations of such bounded collections Much less is known however about infants ability to actually utilize such representations in the guidance of goal directed action The present research is designed to characterize the functional and behavioral significance of object representations in infancy focusing particularly on categorically organized representations The primary research strategy to be used consists of analyzing infants examination and manipulation of novel objects that vary both in visual ie shape and color as well as nonvisual dimensions ie weight In a laboratory procedure twelve-month old infants will explore novel objects of different weights and their subsequent handling of modified test objects will be measured with an electronic motion analysis system Kinematic analyses of infants actions on the test objects will reveal how these actions were prepared in relation to their previous experience with similar objects
