Biopsychology - Lesson 7

What does hemispheric lateralisation refer to? Fill in the blank: Hemispheric lateralisation refers to the notion that certain functions are principally governed by one side of the _____?

• brain

• heart

• liver

• lung

Which hemisphere are language centres typically lateralised to in most people?

• left hemisphere

• right hemisphere

• both hemispheres equally

• neither hemisphere

What is the main function of Broca's area?

• Speech production (enables speech to be fluent)

• Regulation of heart rate

• Processing visual information

• Control of balance and coordination

Damage to which area leads to expressive aphasia?

• Broca's area

• Wernicke's area

• Occipital lobe

• Cerebellum

Damage to which area leads to receptive aphasia?

• Wernicke's area

• Broca's area

• Prefrontal cortex

• Cerebellum

The right hemisphere is dominant for which functions?

• Visuo-spatial functions and facial recognition

• Language comprehension and speech production

• Mathematical calculations and logical reasoning

• Fine motor control and writing

What is the name of the bundle of nerve fibres that connects the two hemispheres and enables information to be communicated between them?

• Corpus callosum

• Medulla oblongata

• Cerebellum

• Thalamus

What is the structure highlighted in orange called?

• Corpus callosum

• Thalamus

• Cerebellum

• Medulla oblongata

What is an advantage of hemispheric lateralisation from an evolutionary perspective?

• It decreases neural processing capacity

• It increases neural processing capacity, which is adaptive

• It makes both hemispheres do the same task

• It prevents multitasking

According to Rogers et al. (2004), hemispheric lateralisation in chickens is associated with the ability to perform two tasks simultaneously.

• True

• False
