Three experiments are described which relate to models of infant visual preferences and to the ways in which preferences can be modified or created by habituation. Results suggest that the Banks and Salapatek's contrast sensitivity model can be a powerful predictor of preferential looking in newborns and that preferences based on experience can be…

Describes preschool children's ability to simultaneously perceive multiple aspects of an object in two experiments during which three- to five-year-olds were asked to describe part/whole pictures. (HOD)

Tests infants' dual-process performance (a process mediating response decrements called habituation and a state-dependent process mediating response increments called sensitization) on visual habituation-dishabituation tasks. (HOD)

Describes two studies in which young children were shown pictures that represented sound with postures and contexts, with conventions, and with combinations of information. Shows that the different types of pictorial representation of sound were not equivalent in their ability to evoke a correct interpretation. (HOD)

Examines whether three-month-old infants can detect variations within the single expression category of smiling and whether individual differences in infants' sensitivities are related to identifiable mother or infant behaviors. (HOD)

Investigates developmental changes in the accuracy of aimed movements made to an illuminated target lamp by children between the ages of 1.5 and 8 years. Shows accuracy decreased with decreasing availability of visual information and improved with age under all conditions. (HOD)
