Exam 11: Hemispheric Specialization

If a split-brain patient with the typical pattern of language dominance is shown an object briefly in her left visual field,she will be able to indicate what she saw successfully if she is asked to

The phenomenon of global precedence described by Navon (1977)is that when hierarchically structured stimuli are presented,

How do the two hemispheres differentially process the local and global elements of visual hierarchical stimuli? How does the spatial-frequency hypothesis explain this?

Lesions of the right hemisphere disrupt perception of ________ in visual stimuli and ________ in speech,according to the frequency hypothesis of hemispheric asymmetry.

In neurologically intact people,we can restrict information to only the left hemisphere by presenting it visually in the right visual field.

Based on what you have learned about laterality,which of the following statements is most accurate?

A general function that is associated with RIGHT-hemisphere activity in most people is

Many callosal projections link homotopic areas in corresponding locations in the two hemispheres.

Split-brain patients are asked to detect targets that appear briefly on a computer screen.On some trials,the targets are preceded by cues that correctly indicate their upcoming location.The detection advantage produced by the cues

One difficulty in interpreting the correlation between asymmetry in the planum temporale and language function that has recently arisen is that

Why might the left hemisphere be more important for the production of facial expressions while the right is more important for perception of the same expressions? In your answer,consider the computational requirements of producing and perceiving expressions.

Delis and colleagues (1986)used not only letter stimuli with their patients but also nonlinguistic hierarchical shape stimuli such as the example here.How did the results differ from those obtained with hierarchical letter stimuli?

The term ________ refers to the idea that a complex perceptual stimulus can be described on multiple levels of detail.

The word superiority effect can be documented

One issue in the study of laterality has been to determine whether children with developmental language disabilities show different patterns of hemispheric asymmetry relative to control populations.MRI studies of dyslexic children have found that

When Sergent (1982)presented lateralized local-global stimuli to control participants,she found that

In speech,the relatively high-frequency components carry information necessary to identifying the ________ in a sentence.

The right hemisphere is more important than the left for both the perception and production of facial expressions.

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

The main mass of fibers that carries signals from the cortex in one cerebral hemisphere to the other is called the
