Document Summary

The contribution of context: change in context results in a change in perception. The stroop effect: the colour activity, our perception of the colour becomes conflicted when the words do not match the colours we are seeing. Is defined as the smallest difference between two stimulus that people can perceive. Sensory adaptation: sensory neurons are engineered to respond to a constant stimulus by decreasing their activity, sensory adaptation: the diminishing sensitivity to an unchanging stimulus, adaptation occurs in all sensory modalities including vision, r. m. Myopia and hyperopia: myopia, nearsightedness, eyeball is longer back to front, lend focuses light in front of retina, difficulty seeing far away objects, hyperopia, farsightedness, eyeball is too short, lens focuses behind retina, difficulty seeing close up. Brightness and dark adaptation: rods and cones translate light waves into nerve impulses through the action of protein molecules called photo-pigments.
