Question 1 1 / 1 pts The cortical magnification factor occurs in humans because a small area in the peripheral retina accounts for a large area on the cortex. the small area of the fovea accounts for a large area on the cortex. the lens accommodates so that the image is magnified on the retina. the area at the optic disk accounts for a large area on the cortex. Question 2 1 / 1 pts Using the techniques of both recording from neurons and ablation, researchers found that properties of the ventral and dorsal streams are established by two different types of what kind of cells in the retina? Bipolar Hippocampus Ganglion LGN Question 3 The results of the patient D.F., who had visual form agnosia, show that perception and action are independent of each other in the brain. the same brain areas are involved in visual orientation and oriented action. the inability to draw items is due to a lack of general knowledge. double dissociations do not occur in these patients. 1 / 1 pts Question 4 1 / 1 pts In Ungerleider and Mishkin’s (1982) research, monkeys who had had their temporal lobes removed had difficulty coordinating their movements. discriminating between objects. discriminating between locations. remembering sequences of actions. Question 5 1 / 1 pts What term refers to the fact that the response properties of neurons can be shaped by an animal’s or person’s perceptual experience. Selective adaptation Neural plasticity Sensory integration Perceptual analysis Question 6 Which statement is true regarding the organization of columns in the cortex? A location column can contain many orientation columns. An orientation column can contain many location columns. Location and orientation columns are in different parts of the cortex. Action columns are present in both location and orientation columns. 1 / 1 pts Question 7 1 / 1 pts The difference in intensity between light bars and dark bars is called orientation. wave form. phase. contrast. Question 8 1 / 1 pts A stimulus that contains alternating black and white bars is called a grating. grid. Boolean array. Moire pattern. Question 9 1 / 1 pts What effect occurs because humans have more cortical neurons that respond to horizontal and vertical orientations than slanted orientations? Oblique Transverse Parallel Box Question 10 1 / 1 pts Ganel et al. (2008) designed a modified visual illusion, in which line 1 appears to be longer than line 2, when, in reality, line 2 is longer. Participants are asked to judge the line lengths and to reach and grab the ends of the lines. The results of this investigation reveal the interaction of the ventral and dorsal stream. that the visual illusion affects both the ventral and dorsal streams. the effects of damage to the ventral pathway. that the illusion only affects ventral stream processing. Question 11 1 / 1 pts A large object, such as a tree trunk, will cause every neuron in one location column to fire, but no firing in any other column. a limited number of neurons to fire in only one ocular dominance column. firing of neurons in a number of different columns. every neuron in an orientation column to fire, but not in the location columns. Question 12 When a kitten is exposed to an environment of just horizontal lines, the kitten would pay attention only to vertical lines. would pay attention only to horizontal lines. would have cortical cells that only respond to vertical lines. 1 / 1 pts would have cortical cells that respond to horizontal lines, but none to vertical lines. Question 13 1 / 1 pts To which lobe does the dorsal pathway go? Temporal Frontal Parietal Occipital Question 14 1 / 1 pts A researcher finds that damage to Area A of the brain results in the loss of Function A, but not Function B. In another individual, damage to Area B results in the loss of Function B, but not Function A. These results are best described as a(n) associative link. double dissociation. single dissociation. differential assessment. Question 15 What is the name of the area in the temporal lobe that specializes in recognizing faces? FFA RBC Parietal area 1 / 1 pts Area 4H Question 16 1 / 1 pts According to Milner and Goodale, the dorsal stream is what kind of pathway? What When How Why Question 17 1 / 1 pts Ablation is a procedure in which a radioactive isotope is injected into the bloodstream and traced through the brain. electrodes on the scalp are used to measure changes in brain activity. a particular area of the brain is removed or destroyed. an electromagnetic pulse is used to temporarily disrupt brain activity. Question 18 1 / 1 pts An electrode is placed in an orientation column that responds best to orientations of 45 degrees. The adjacent column of cells will probably best respond to orientations of 5 degrees. 40 degrees. 90 degrees. 175 degrees. Question 19 1 / 1 pts Most signals travel via the optic nerve from the retina to the temporal cortex. lateral geniculate nucleus. the superior colliculus. the visual homunculus. Question 20 Patient H.M. had his what removed in order to control his epileptic seizures? Hippocampi IT cortex Striate cortex Corpus callosum 1 / 1 pts
