S.D.3-3 7. What is selective adaptation? How does it work and why it is useful for studying visual perception? Selective adaptation refers to the phenomenon where prolonged exposure to a specific stimulus (such as a particular orientation of lines) leads to a temporary reduction in sensitivity to that stimulus. This occurs because neurons that respond to the stimulus become less responsive over time. Selective adaptation is useful for studying visual perception because it reveals the tuning properties of neurons and shows how the brain processes specific features like orientation and spatial frequency. 8. Explain the concept of a critical period in visual development. How does contrast sensitivity in infants develop? How might it be affected by developmental disorders such as amblyopia, strabismus or anisometropia? -->

The critical period refers to a specific time in early development when the visual system is especially sensitive to environmental stimuli. If proper visual input is not received during this period, normal visual development can be disrupted. Contrast Sensitivity Development – infants initially have poor contrast sensitivity but it improves rapidly during the first few months of life as the visual system matures. Developmental disorders: Amblyopia – often caused by uncorrected vision problems early in life, it leads to reduced vision in one eye because normal visual experience is disrupted during the critical period. Strabismus – misalignment of the eyes can disrupt binocular vision during the critical period, leading to problems with depth perception. Anisometropia – when the two eyes have significantly different refractive errors, the brain may suppress input from one eye, which can lead to amblyopia if untreated.
