split brain/hemispheric lateralisation Flashcards
(32 cards)
What is hemispheric lateralisation?
The specialization of the left and right hemispheres of the brain for different functions.
True or False: The left hemisphere is primarily responsible for language processing.
True
What is the primary function of the right hemisphere?
It is primarily involved in spatial awareness and creative tasks.
Fill in the blank: The corpus callosum is a bundle of _____ that connects the two hemispheres of the brain.
nerves
Who conducted the pioneering split-brain research?
Roger Sperry
What is a split-brain procedure?
A surgical operation that cuts the corpus callosum to reduce seizures.
Multiple Choice: Which of the following tasks is typically associated with the left hemisphere? A) Recognizing faces B) Mathematical calculations C) Artistic tasks
B) Mathematical calculations
What behavior was observed in patients with split brains when shown an object in their right visual field?
They could verbally identify the object.
True or False: Patients with split brains can verbally describe objects seen in their left visual field.
False
What happens when a split-brain patient sees an object in their left visual field?
They can draw the object but cannot name it.
Fill in the blank: The _____ hemisphere is more involved in analytical thinking.
left
What is the concept of ‘cross-cuing’ in split-brain research?
It refers to non-verbal cues used by one hemisphere to communicate with the other.
Multiple Choice: Which hemisphere is typically dominant for language in right-handed individuals? A) Left hemisphere B) Right hemisphere
A) Left hemisphere
What is the primary conclusion from split-brain studies?
Each hemisphere has specialized functions and can operate independently.
True or False: Split-brain patients demonstrate no differences in personality after the procedure.
True
What is the role of the right hemisphere in language processing?
It contributes to understanding context and emotional tone.

Multiple Choice: Which of the following tasks would likely be easier for the right hemisphere? A) Solving a math problem B) Recognizing a melody C) Reading a text
B) Recognizing a melody
What is the significance of the ‘Z lens’ in split-brain research?
It allows researchers to present stimuli to one hemisphere at a time.
True or False: Split-brain research has implications for understanding consciousness.
True
What does the term ‘lateralisation of function’ imply?
Different cognitive processes are localized in specific hemispheres.
Fill in the blank: The _____ hemisphere is often referred to as the ‘logical’ hemisphere.
left
What is one limitation of split-brain studies?
They primarily involve individuals with severe epilepsy.
