42) In normal humans, color space has 3 dimensions (3 primaries can match all colors) because (a) our perceptions are related to objects in the real world. (b) each retina is a two-dimensional representation of the world, but we have two eyes. (c) the retina contains three types of cones, or functions as if this were true. (e) None of the above. 43) The spectral sensitivity of a single cone depends on (a) the spectral absorption curve of the photopigment it contains. (b) whether it is light or dark adapted. (c) whether it is part of the center or surround of a receptive field. (d) the wavelengths of the lights in a trichromatic mixture. 45) Two people stand in the corners of the Ames trapezoidal room; when they are viewed monocularly, the one that appears much taller is perceived as being (a) much closer and hence seems taller. (b) much farther and hence seems taller. (c) at the same distance as the other person even though the retinal image of him is larger. (d) taller because the room appears to be distorted. 52) If all the receptors in a person's retina contain the same photopigment, that person will (a) have some color vision, but only if the stimuli are presented to the fovea. (b) have some color vision, but only when fully light-adapted. (c) be color-blind because all receptors would respond equally to any stimulus. (d) be partially color-blind, because long wavelength photons are always less energetic. 58) Preattentive processing of the visual image (a) is a parallel process allowing processing of many targets at the same time. (b) refers to primitives that are combined in a slower focused-attention stage. (c) is pop-out segregation of objects seen in crossed disparity. (d) All the above are true. 60) In his approach to depth perception, J.J. Gibson emphasized the importance of texture gradients in a scene because (a) they are very important for the correct operation of binocular stereopsis. (b) the depth information from the texture of the ground usually remains constant provided the elements of the texture all have the same physical dimensions. (c) interposition cues are more important when a texture gradient is present. (e) None of the above.

Activity of retinal ganglion cells that have an excitatory center and an inhibitory surround to their receptive field allows: A. the conscious awareness of objects B. the detection of color C. detection of contrast by responding to a border within the receptive field D. perception of depth Visual acuity is best in the center of our visual field. What is the best explanation for this? A. retinal ganglion cells in the fovea have a small receptive field receiving information from a single photoreceptor cell. B. retinal ganglion cells in the fovea have a large receptive field receiving information from many photoreceptor cells. C. photoreceptor cells in the fovea are mostly rods. D. photoreceptor cells in the fovea are mostly cones.

In a perception research lab, you are asked to describe the shape of the top of a box as the box is slowly rotated. Which concept are the researchers most likely investigating? (A) feature detectors in the retina (B) feature detectors in the occipital lobe (C) placement of rods and cones in the retina (D) binocular depth cues (E) shape constancy

00:01 The question that is given over here, this is regarding the color space.

00:06 The question is, in normal humans, the color space has three dimensions, because of which of the following? group of answer choices are given and we have to select the right answer for this question.

00:21 Here, the process of seeing color is intricate and it involves the eyes, brain and the environment.

00:38 The photoreceptors, they are the specialized cells, which is found in our human eye.

00:50 They are in charge of sensing the light and sending messages to the brain.

00:57 The human eye, it contains the rods and the cones, that is, they are the two different types of photoreceptors...
