Exam 11: Hemispheric Specialization

Asymmetries in language-associated brain regions have been documented at the level of individual neurons that make up the cortical columns.

According to Corballis's (1991)The Lopsided Ape,the left hemisphere is specialized to generate complex representations from a small vocabulary of primitive units,such as phonemes,articulatory gestures,or words.This left-hemisphere mechanism is called the

Support for the view that the left hemisphere is specialized for categorical information processing is that there is a ________ hemisphere advantage for processing information about ________.

Despite the generalization that the left hemisphere is dominant in language function,one important aspect of language that is associated primarily with the right hemisphere is

The following is a sample stimulus shown briefly to a split-brain patient who has the typical pattern of language dominance.If you ask her to name the object she sees,what will her answer probably be?

Split-brain research is associated with which of the following?

Based on what you know about the neurophysiological and microanatomical differences between the right and left hemispheres,choose the option here that correctly lists the properties of cortical tissue samples taken from the left hemisphere.

To which of the following aspects of language does the right hemisphere seem to make the SMALLEST contribution,if any?

In an experiment testing their views about hemispheric specialization,Wolford and colleagues (2000)presented the visual fields of split-brain patients with red stimuli on 75% of the trials and with green stimuli on 25% of the trials.The predictions made by the patients concerning whether a red or green stimulus would occur on the next trial suggested that the ________ hemisphere tends to take a ________ strategy,which in this case meant guessing red on every trial.

The results of studies investigating the processing of local-global figures and sinusoidal spatial-frequency gratings can be tied together within the spatial-frequency hypothesis by which of these facts?

An anatomical difference between the cerebral hemispheres that may be related to language lateralization is the enlargement of the ________ in the left hemisphere.

You hear someone utter the sentence "Cognitive neuroscience is fascinating." Your ability to infer whether the speaker intended to convey her genuine interest in cognitive neuroscience or to make a sarcastic comment indicating just the opposite depends on your ability to process the ________ components in the speech signal.

When participants in a dichotic listening task with word stimuli are asked afterward to report as many items as possible,they consistently produce the words that were presented to the right ear much more frequently than the words that were presented to the left ear.This phenomenon is called

There appear to be two mental lexicons,one in each hemisphere.

The dichotic listening task has been used to show a left-ear advantage for remembering dichotically presented words,consistent with the idea that the left hemisphere processes language.

Here are a hierarchical letter figure and a copy of this stimulus drawn by a person with a unilateral brain injury.Where is the most probable location of this injury?

Which of the following people would be most likely to receive the split-brain procedure?

Studies of the production of facial expressions suggest that although ________ can generate spontaneous facial expressions,________ can generate voluntary facial expressions.

The idea that the visual system carries out information processing similar to Fourier analysis is supported by the observation that

The spatial-frequency hypothesis explains a variety of findings using visual local-global stimuli.How might an auditory version of this hypothesis explain cerebral asymmetries in language?
