- Watch this video (http://openstaxcollege.org/l/l_3-D1) to learn more about how the brain perceives 3-D motion. Similar to how retinal disparity offers 3-D moviegoers a way to extract 3-D information from the two-dimensional visual field projected onto the retina, the brain can extract information about movement in space by comparing what the two eyes see. If movement of a visual stimulus is leftward in one eye and rightward in the opposite eye, the brain interprets this as movement toward (or away) from the face along the midline. If both eyes see an object moving in the same direction, but at different rates, what would that mean for spatial movement?arrow_forwardQ10.

- Watch this video (http://openstaxcollege.org/l/occipital) to learn more about a transverse section through the brain that depicts the visual pathway from the eye to the occipital cortex. The first half of the pathway is the projection from the RGCs through the optic nerve to the lateral geniculate nucleus in the thalamus on either side. This first fiber in the pathway synapses on a thalamic cell that then projects to the visual cortex in the occipital lobe where seeing, or visual perception, takes place. This video gives an abbreviated overview of the visual system by concentrating on the pathway from the eyes to the occipital lobe. The video makes the statement (at 0:45) that specialized cells in the retina called ganglion cells convert the light rays into electrical signals. What aspect of retinal processing is simplified by that statement? Explain your answer.arrow_forwardBlind Spot Why don't you perceive a blind spot as you go about your daily tasks?arrow_forward4a) Which of the following is true about infants’ visual acuity? Select one: i. Poor visual acuity early in life allows key features of the visual world to “pop out” ii. Before 3 months, infants are not able to make sense of their visual world iii. It’s not possible to test visual acuity before infants are 6 months iv. Newborns have poor visual acuity, but excellent colour vision 4b)You see the results of an eye-tracking study in which infants were required to look at human faces. You see that infant A spent most time looking at the contour of the face, while infant B spent a lot of time looking at the eyes and the mouth. You conclude that infant B is most likely: Select one: i. Showing signs of a developmental disorder ii. Older than infant A iii. Bilingual iv. Younger than infant A 4c)Which statement is FALSE regarding infants’ perception abilities at birth? Select one: i.
