Chapter Twenty-One The Resting Brain, Attention, and Consciousness1. What is the evidence that it is possible to shift attention to objects that are imaged on
parts of the retina outside the fovea? Choose the correct option.
A) A cue that directs attention to an image that is about to appear to the right or the
left of the fovea improves visual detection and reaction time
B) Individual neurons in the frontal eye fields fire during a saccade to a specific target
C) Invalid, neutral, and valid cues all have the same impact on visual detection and
reaction time.
D) Attention has a direct effect on visual transduction and motor coding.
2. Which of the following describes the neglect syndrome observed after right
posterior parietal lesions? Choose the correct option.
A) Specific types of objects are completely ignored.
B) Specific individuals are completely ignored.
C) Everything to one side of the center of gaze is completely ignored.
D) Specific body parts on both sides are completely ignored.

Choose the correct option.
A) The midline of her body
B) Too far to the right of her body
C) Too far to the left of her body
D) To a part of her body on her dominant side
4. What happens to brain activity in the visual cortex when subjects are forced to attend to
parts of the visual field outside the fovea? Choose the correct option.
A) The pattern of brain activity shifts retinotopically.
B) The whole retinotopic map becomes active in the visual cortex.
C) Activity in the primary visual cortex ceases and the extrastriate cortex takes over.
D) Visual areas outside the occipital cortex participate in this type of task.
5. PET imaging during an experiment studying the effect of attending to specific features
of a visual stimulus showed the greatest brain activity for moving stimuli occurred in
which area of cortex? Choose the correct option.
A) Area 17
B) IT
C) MT
