Paivio proposed the conceptual peg hypothesis. His work suggests which of the following would be most difficult to remember?
Freedom
The pegword technique is particularly suitable for use when you need to remember items based on their
order
Your text describes the case of M.G.S. who underwent brain surgery as treatment for severe epilepsy. Testing of M.G.S. pre- and post-surgery revealed that the right visual cortex is involved in the
size of the field of view.
The water-pouring problem, in particular, shows that its solution using imagery cannot depend on
tacit-knowledge.
Suppose that, as a participant in an imagery study, you are asked to memorize the four outside walls of a three-story rectangular house. Later, you are asked to report how many windows are on the front of the house. You will probably be fastest to answer this question if you create an image as though you were standing
at the far side of the front yard, away from the house.
In drawing conclusions about the relationship between imagery and perception, a notable difference between them is that
it is harder to manipulate mental images than perceptual images.
Shepard and Metzler measured the time it took for participants to decide whether two objects were the same (two different views of the same object) or different (two different objects). These researchers inferred cognitive processes by using
mental chronometry.
Kosslyn's island experiment used the _____ procedure.
mental scanning
Ben has had problems with the pipes in his apartment. First, he had a clog in his bathroom sink, and then two months later, his garbage disposal in the kitchen sink clogged. Ben's superintendant told him he was not adequately flushing the debris from his pipes. She suggested that he run the water a little longer and visualize the debris (be it carrot peelings or toothpaste) traveling through the pipes all the way out to the sewer connection in the street. Using this technique, Ben has had no more clogs. The superintendant's suggestion involved
mental scanning.
Perky's imagery study from the early 1900s had participants describe images of objects that were dimly projected onto a screen. The significance of Perky's results was that
people were unconsciously influenced by the projected images when forming their mental images.
