Intermodal Perception of Affect Expressions by Infants.
Walker, Arlene
Four experiments (E1, E2, E3 and E4) investigated whether or not 5- to 7-month-old infants could detect auditory-visual relationships in audiovisual presentations of affective expressions, thereby perceiving the bimodally-presented expressions as unitary events. In E1, 16 infants were simultaneously shown two 2-minute films of a "happy" and a "neutral-to-serious" woman. During the presentation of the two filmed facial expressions, a single sound track was played. Each infant viewed the two films twice, one time with the sound track from the happy film and once with the neutral sound track. Visual fixation was recorded. A second group of infants was shown the two filmed facial expressions simultaneously but without an accompanying sound track. Infants viewing the silent films showed no significant differences in attention to either of the films. Infants viewing the sound films showed a preference for the happy film but also looked longer at the film accompanied by sound, whether the image projected was happy or neutral. Variations of E1 were conducted in E2, E3 and E4: E2 eliminated the silent film condition and presented happy and sad expressions; E3 eliminated synchrony between lip movement and audible speech; and E4 presented happy and angry expressions, half of which were presented upside down. In general, results were as in E1, except that infants increased their looking time while viewing the asynchronous sound film and showed no difference in looking time when films were presented upside down. It is concluded that 5- to 7-month-old infants detect information that is invariant across optic and acoustic displays of a single, affective expression. (Author/RH)
