Exam 10: Visual Imagery

Suppose you were conducting a brain imaging experiment to investigate the overlap between brain areas activated by perceiving an object and those activated by imagining it.Which of the following best describes your investigation's baseline condition?

Mental imagery involves

In their imagery study, Finke and Pinker presented a four-dot display briefly to participants.After a two-second delay, participants then saw an arrow, and their task was to indicate whether the arrow would have pointed to any of the dots in the previous display.The significance of their results was they called into question the ____ explanation of imagery.

"Early" researchers of imagery (beginning with Aristotle until just prior to the dominance of behaviorism)proposed all of the following ideas EXCEPT

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

Describe in detail two techniques that use imagery to improve memory.Explain the underlying principles that define why imagery works successfully as a memory enhancer.

The lesson to be learned from the imagery techniques for memory enhancement (for example, the pegword technique)is that these techniques work because

Ganis and coworkers used fMRI to measure brain activation for perception and imagery of objects.Their results showed that

The rule-based approach to mechanical problem-solving is analogous to the idea that visual imagery involves ____ representations.

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

Which of the following has been used as an argument AGAINST the idea that imagery is spatial in nature?

Describe the evidence showing that solving mechanical problems can involve mental simulation, and explain how this evidence relates to visual imagery.

Transcranial magnetic stimulation is used to

Kosslyn interpreted the results of his research on imagery (such as the island experiment)as supporting the idea that the mechanism responsible for imagery involves ____ representations.

Explain the mental walk task.Describe the concept of "overflow" as it applies to the imaging of large and small objects.What do the results of mental walk experiments tell us about properties of the image field? Which side of the "imagery debate" do these findings support?

Kosslyn's transcranial magnetic stimulation experiment on brain activation that occurs in response to imagery found that the brain activity in the visual cortex

Describe the spatial and propositional explanations of the mechanisms responsible for imagery.Also, explain how the propositional explanation would account for the results of Kosslyn's island mental-scanning experiment.

In drawing conclusions about the relationship between imagery and perception, a notable difference between them is that

Suppose we asked people to form simultaneous images of two or more animals such as a rabbit alongside an elephant.Then, we ask them basic questions about the animals.For example, we might ask if the rabbit has whiskers.Given our knowledge of imagery research, we would expect the fastest response to this question when the rabbit is imagined alongside
