Vision-to-touch and touch-to-vision transfer of form in 5-month-old infants

Investigated 5-mo-old infants' cross-modal transfer of form from vision to touch and from touch to vision. 32 Ss (aged 4 mo to 5 mo 24 days) and 16 Ss (age 4 mo 2 days to 5 mo 9 days) participated in Exps I and II, respectively. Evidence of cross-modal transfer in infants was defined as (1) exploring a familiar object presented in a new modality less than a novel object presented in a new modality, (2) remaining habituated to the familiar object in the 1st modality after presentation of that object in the 2nd modality, and (3) discriminating objects intramodally. In Exp I, Ss were familiarized with an object visually or tactually until a habituation criterion was reached, after which they received 3 tests in which the same or a different object appeared in the same or a different modality. The dependent variable was the duration of a look or grasp. Cross-modal transfer was found from vision to touch, but not from touch to vision. In an attempt to employ a different test of touch-to-vision transfer in Exp II, Ss were tactually familiarized with an object and then given a visual preference test; cross-modal transfer from touch to vision again did not occur. Findings are discussed in terms of the perception of modality-specific object properties and the development of eye-hand coordination.
