Stress causes the body to release substances that increase inflammation, which can prolong infections and delay healing

Banks and Barber (1971) presented subjects with a matrix of letters where each row was of a different color and then cued with color to indicate which row the subjects should report. They found:

A. That subjects rarely reported the row that was in the complementary color, suggesting that iconic memory is not like an afterimage. B. That subjects commonly reported the row that was in the complementary color, suggesting that iconic memory is like an afterimage. C. That color was not as effective a cue as the tones that were used in the original Sperling studies. D. That subjects tended to report both the required row and the row that was in the complmentary color, suggesting that iconic memory has some of the properties of an afterimage.

Two patients with optic ataxia both made grasping movements towards a target object. What does this tell us?

a) They needed real time bottom-up guidance for object identification. b) There is memory involvement in the ventral stream, because these patients could use their ventral stream as it was intact. The grasping demonstrated top-down processing. c) These patients cannot recognise objects and wanted to use touch sense to identify it. d) There wasn't memory involvement because their dorsal stream was intact and that is what was needed to grasp.
