Document Summary
Time during development where certain experiences are essential to process normally. Konrad lorenz imprinting in birds first few seconds of hatching, whatever they see, they follow. Period of time which experience is optimal for development of a function but not critical. We infer what babies see by altering environmental stimuli and observing their behaviour: visual scanning (what infants look at) 1m fixated on corners and edges of triangle. 2m focus on middle of face (more important info: habituation (distinguish between two stimuli) Suck rates as babies get bored, length of time to look away decreases. Given different pictures compared to same image. Teller acuity high contrast vs low contrast. Babies visual acuity improves in first few months. Newborns can see all colour cannot distinguish brightness. E. g. ability to discriminate faces from other species. Longitudinal design, infants: 6 and 9 months tested: visual preferences. Given range of images, measured time taken to look away. Babies prefer real faces over scrambled faces.
