Document Summary
Sensing- processing of basic information from the external world by receptors in the eyes, ears, skin, tongue, and nose. Perceiving- organization and interpretation of sensory information about the world. Visual acuity- sharpness of our visual perception. Approach adult visual acuity by 6-8 months. Full acuity by 6 years of age. Preferential looking- two different visual stimuli are displayed side by side. If the infant looks longer at one researcher can infer that: The child would rather look at a pattern than at something plain. 2-month-olds use common motion to segregate objects. Older infant (8 months +) and adults can use world experience. Repeatedly presenting an image until the infant"s response decreases. If the infant dishabituation in response to novel stimuli researcher can conclude that the infant can discriminate between the old and new stimuli. 2-month-old infant looks more eyes and mouth. Looking into the eyes creates an attachment and starts familiarization. By 3 months they prefer their own race faces.
