Question
In one of the earliest studies of visual attention, Helmholtz
(1894) constructed a screen on which letters were painted at
various distances from the center. Following a brief
illumination, he found that
a. he could perceive letters located within the focus of his
attention better than letters outside, even when his eyes
remained at the center of the screen.
b. although he was unable to remember all the letters on the
screen, he could be cued to attend to the top, middle, or bottom
row by a tone played just before the illumination.
c. he could perceive letters located within the focus of his
attention better than letters outside, but only if he moved his
eyes to bring the letters to the center of his visual field.
d. he could remember all the letters on the screen, demonstrating
that visual iconic memory increases in capacity with attentional
focus.

Q:
Assessment of the visual processing carried out by each hemisphere in split-brain patients usually involves the brief simultaneous presentation of different stimuli to each visual field while the participant fixates on a central point in space. Why is it necessary to ensure that stimulus presentation is brief? a.If the stimuli were presented over longer intervals, information would be transferred between the hemispheres through the corpus callosum. b. Brief presentation prevents participants from focusing attention on the stimuli. c.The short presentation time is necessary to prevent eye movements, which would redirect information across the visual fields. d. Increasing the presentation time increases task difficulty for split-brain patients.
Q:
Although there is a general consensus that the right hemisphere is superior on some tasks that require visuospatial processing, such as the block design task, the findings on this topic are also somewhat inconsistent. One explanation for this inconsistency is that the block design task a.involves many cognitive operations, and not all of them may be lateralized to the right hemisphere. b. has many verbal components that may emphasize left- rather than right hemisphere function. c.requires fine motor coordination, which is regulated by the right hemisphere. d. is too simple a task to demonstrate strong laterality effects.
Q:
The word superiority effect can be documented a.in only the left hemisphere because this effect stems from the auditory lexicon. b.in both hemispheres because this effect stems from the auditory lexicon. c.in only the left hemisphere because this effect stems from the visual lexicon. d.in both hemispheres because this effect stems from the visual lexicon.
Q:

Q:
Which of the following statements best describes the correlation between handedness and hemisphere dominance for language function in humans? a.The correlation is strong, such that for language almost all right-handers have left- hemisphere dominance and almost all left-handers have right-hemisphere dominance. b. The correlation is strong only for right-handers, who almost all have left-hemisphere dominance for language, whereas left-handers do not generally have a particular language- dominant hemisphere. c.The correlation is strong only for left-handers, who almost all have right-hemisphere dominance for language, whereas right-handers do not generally have a particular language-dominant hemisphere. d. The correlation is weak, such that almost all right-handers and at least half of left-handers exhibit left-hemisphere language dominance, regardless of handedness.
