Lateralization and Split-Brain Research

What is the primary function of the left hemisphere (LH) for most people?

• Synthesizer

• Analyser

• Emotional center

• Motor control

Which hemisphere is responsible for synthesizing information?

• Left hemisphere

• Right hemisphere

• Both hemispheres

• Neither hemisphere

What is the typical function of the right hemisphere (RH) in terms of language?

• Analyser

• Synthesizer

• Dominant for language

• Silent but emotional

In split-brain research, what happens when an object is shown to the right visual field (RVF)?

• The person cannot describe the object

• The person describes the object

• The person giggles but reports nothing

• The person selects the item with the left hand

What is the result when an object is shown to the left visual field (LVF) in split-brain research?

• The person describes the object

• The person says 'nothing there'

• The person selects the item with the right hand

• The person laughs but reports nothing

What is the conclusion about the lateralized brain in split-brain research?

• LH is silent and RH is verbal

• LH is verbal and RH is silent but emotional

• Both hemispheres are silent

• Both hemispheres are verbal

What is the role of the right hemisphere (RH) in a connected brain according to Fink et al.?

• Processes global elements

• Processes finer details

• Dominant for language

• Controls motor functions

According to the document, what does lateralisation enable in animals like chickens?

• Emotional expression

• Multitasking

• Language development

• Memory retention

What is a confounding variable when comparing split-brain participants to 'normal' controls?

• Language ability

• Emotional response

• Epilepsy

• Motor skills

What ethical issue is highlighted in the evaluation of split-brain research?

• Lack of informed consent

• Lack of control group

• Inaccurate data collection

• Overgeneralization
