Exam 4: Hemispheric Specialization

A small object, such as a key, is placed in the right hand of a split-brain patient who has her eyes closed. Assuming that this person has left-hemisphere language dominance, which of the following best describes her ability to report information about the object based on how it feels?

You are watching a show on TV while speaking on your cell phone to a loved one. A commercial with a couple fighting appears. Suddenly, the person says something on the phone and you get irritated. The person on the other side of the line is perplexed by your response. This is an example of

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

Localized specialized networks that can perform functions are called

Animals and humans are shown items that have a 75/25 probability of being in one of two categories. Which participants would perform the best on this task?

Describe how modularity plays a role in consciousness.

Based on the work of Navon (1977), which of the following types of stimuli would probably produce the shortest reaction times if participants were required to detect the presence of an "L" in the figure?

Damage to the right hemisphere is known to cause visual spatial function deficits. Give an example of a result from an experiment that supports this.

The posterior and anterior commissures are NOT thick enough for which of the following?

Visual information that is presented briefly to the ________ visual field is processed first by the left half of each retina and then by the ________ hemisphere of the brain.

On which basis 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.

In an experiment with patients, a group of researchers used nonlinguistic hierarchical shape stimuli such as the example here. How did the results differ from those obtained with hierarchical letter stimuli?

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

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

Imagine that you are a neurologist and you have a child patient whom you suspect has agenesis of the corpus collosum (ACC). During a meeting with the child's parents, which of the following complaints are they LEAST likely to report?

Some people suggest that the loss of visual spatial ability is due to the acquisition of language. Give an example of this from work with nonhuman primates.

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?

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

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

Theory of mind is to the interpreter as the _______________ is to the _______________.
