U2 AoS2 DP 3b Gustatory Perception

As people age, their ability to taste certain flavours:

• Increases due to more taste buds

• Stays the same throughout life

• Decreases due to loss of taste buds

• Becomes more sensitive to all flavours

Which age group is typically more adverse to bitter tastes?

• Infants

• Adolescents

• Adults

• Elderly

Gustatory receptors are:

• molecules in your saliva which breaks down food

• cells that perceive the chemical molecules in food and drink

• tiny structures on the tongue

• a type of receptor cell found within taste buds

How do genetic differences influence taste perception?

a) They determine the amount of saliva produced, which affects taste
b) They affect the number and sensitivity of taste receptors on the tongue
c) They have no significant impact on taste perception
d) They alter the color of food, influencing its taste

• They affect the number and sensitivity of taste receptors on the tongue

• They alter the colour of food, influencing its taste

• They have no significant impact on taste perception

• They determine the amount of saliva produced - which affects taste

Which of the following best describes the impact of aging on taste perception?

• Older adults are more sensitive to all flavours

• Taste perception remains unchanged with age

• Taste sensitivity to salty and sweet flavours tends to decline with age

• Older adults have heightened sensitivity to bitter flavours only

Emma walks past a bakery and smells fresh raspberry muffins. She is reminded of memories making raspberry muffins with her grandparents at their home. Which part of the brain may be responsible for this flashback?

• Gustatory cortex

• Amygdala

• Hippocampus

• Prefrontal cortex

• The smell/ taste of broccoli may trigger a negative memory

Evie brought KitKats in a different coloured packet to share with her friends. They all claimed it tasted different. Why might that be the case?

• Different coloured packets of KitKats created a different expectation

• Because the KitKats were bought from Aldi

• Blue KitKats did not look as appealing as Red KitKats

• Red is often associated with sweetness, the blue packet may have cut the expectation back

Parts of the cerebral cortex involved in gustatory perception are:

• Gustatory cortex, amygdala, and thalamus

• Hippocampus, gustatory cortex, and medulla

• Amygdala, gustatory cortex, and hippocampus

• Cerebrum, amygdala, and gustatory cortex
