Infant Lab Terms from Encyclopedia Chapter

Some  of my notes from Bahrick, Hollich – Encyclopedia Chapter:

Intermodal perception/intersensory perception – the perception of unitary objects or events that make information simultaneously available to more than one sense

Intersensory redundancy: when the same amodal info is simultaneously available through difference senses

Intersensory redundancy hypothesis: amodal properties are detected easier in multimodal stimulation than in unimodal stimulation; modality specific properties are detected easier in unimodal stimulation; “facilitating attention to amodal information but impairing attention to modality-specific information in multimodal events”

Event perception: amodal relations provide basis for selecting unitary sights and sounds

Audiovisual perception: synchronized sight and sound

Speech perception: language units visual with auditory stimulation

Face-voice perception: broad during first year and narrows as infants have more experience with human faces than other faces; infants able to match unfamiliar faces and voices based on age and gender of speaker (i.e. males have deeper voices than children); link shape of a person’s mouth with sounds they make

Self-perception: visual-motor perception – infants can discriminate between self and others

Amodal information: not specific to a particular sense; can be characterized: time, space, and intensity

Modality-specific information: one particular modality (color, pattern, temperature)

Visual-tactile perception: information relating to shape, texture, substance, and size of object invariant across visual and tactile stimulation; tactile exploration facilitates their perception of amodal, 3-D shape of objects

Visual-motor perception: infants able to perceive their own body motion by detecting amodal info; proprioception is information about self-motion provided by feedback by muscles, joints, and vestibular system; infants take amodal info between proprioception experience of their own limbs motions and of visual image in a video to make a discrimination between self and other; visually guided reaching; posture-control
