Four basic methods of studying infant perception are the preference method, the habituation method, the method of evoked potentials, and the high-amplitude sucking method. Give the procedures for each
What will be an ideal response?
In the preference method, two or more stimuli are presented simultaneously; the amount of time the infant attends to each stimulus is then recorded and compared. In the habituation method, two stimuli are presented sequentially, and the researcher assesses infant behavioral changes such as head and eye movements, respiration, and heart rate to determine if the infant discriminates the two stimuli. The method of evoked potentials assesses changes in brain-wave patterns to determine if the infant discriminates two or more stimuli. Finally, the high-amplitude sucking method employs a pacifier-like response device that indicates the infant's rate of sucking. The researcher assesses whether sucking rate changes as stimuli change, as in the habituation method, or perhaps whether the infant will suck at different rates to produce different stimuli, as in the preference method.
