Cognitive Nsc Exam 3 - Chapter 7 Study Guide Test.

COGNITIVE NSC EXAM 3 - CHAPTER 7 STUDY GUIDE TEST. The main deficit in Balint's syndrome is that patients can focus attention on only a. contralesional objects. b. ipsilesional objects. c. one object at a time. d. the foveal part of the visual field. - CORRECT ANSWER one object at a time. The term ________ refers to the operations involved when we select for further processing a limited subset of information from the total information available to us from our sensory systems and stored mental representations. a. arousal b. vigilance c. attention d. cuing - CORRECT ANSWER attention ________ refers to the ability to choose certain sensory inputs for further information processing while ignoring others. a. Vigilance c. Visual search b. Arousal d. Selective attention - CORRECT ANSWER visual search Attention can be divided into two broad categories: a. neglect and extinction. b. voluntary and reflexive. c. cortical and subcortical. d. conscious and unconscious. - CORRECT ANSWER voluntary and reflexive Which component of attention is associated with the pulvinar? a. the ability to engage visual attention at a particular location in the visual field b. the capacity to move the focus of visual attention from one location to another c. the ability to disengage attention from a particular location in the visual field d. the ability to locate a conjunction target that is embedded in a field of distracters - CORRECT ANSWER the ability to engage visual attention at a particular location in the visual field Injury to which brain structure results in a deficit in moving focused attention from a particular location in the visual field to another? a. the posterior parietal lobe b. the pulvinar nucleus of the thalamus c. the superior colliculus d. the lateral geniculate nucleus of the thalamus - CORRECT ANSWER the superior colliculus Joan is a patient who had a stroke in her right parietal lobe and has extinction as a result of her injury. When placed in a driving simulator she would be most likely to miss which stimulus when stopped at a virtual crosswalk and staring straight ahead? (Note: For this question, assume drivers sit on the left side of the car.) a. a pedestrian on the driver side b. a pedestrian on the passenger side c. a pedestrian on the driver side when a second pedestrian is on the passenger side at the same time d. a pedestrian on the passenger side when a second pedestrian is on the driver side at the same time - CORRECT ANSWER a pedestrian on the driver side when a second pedestrian is on the passenger side at the same time Patients with extinction are unable to detect a visual stimulus presented on the contralesional side of space if a. the stimulus is presented alone in the visual field. b. this stimulus is presented at the same time as a stimulus on the ipsilesional side of the visual field. c. there is no cue that precedes the stimulus. d. the stimulus is presented with another at a more lateral position in the contralesional visual field. - CORRECT ANSWER this stimulus is presented at the same time as a stimulus on the ipsilesional side of the visual field.
