What influences development -> nature (maturation) vs. nurture (learning) Increase in weight (350-1400g) due to glial cells & myelination. Cortical development mirrors emergence of ability: frontal lobe develops last. Very much like adult: suck faster for sweet liquid, reject salty liquid, pleasant expression for bananas, frown for rotten eggs, suggests hardwired. Responds to wide variety of sounds: prefer complex sounds, especially sensitive to sounds in range of human voice. 1st few days: turn head toward sounds, discriminate sound sequences. Retina not completely formed: 1st day gaze at nearby objects and people. Turn head to keep object in view. Visual accommodation not well developed, but can focus 18- Improves steadily over first eight months: 3-4 months some depth perception (roughly just object distance)
