QLD Unit 1 Neuroplasticity

When does plasticity of the brain occur?

• only in childhood
• only in response to medication
• as a result of a head injury
• throughout life

What does synapse formation during learning involve?

• circuit pruning
• pruning
• the process of myelination
• development of neural pathways

Jade and her parents moved to Australia from Vietnam when Jade was an infant. Now that she is an adult, Jade speaks English fluently whereas her parents still struggle to speak English. Why might this be?

• Jade’s parents were too old for their brains to form any new neurological pathways when they moved to Australia.
• Adult brains display less plasticity for language acquisition than a young child’s brain.
• Adult brains display more plasticity for language acquisition than a young child’s brain.
• The development of brain plasticity means that it is impossible to learn a new language after childhood.

Which statement is true about developmental plasticity?

• It is a typical feature of childhood.
• It is evident in both a child’s brain and an adult’s brain.
• It occurs only in people recovering from serious brain injuries.
• It is more evident in some areas of the brain than in other areas of the brain.

What does the term ‘adaptive plasticity’ refer to?

• changes in the brain in response to hormones
• changes in a newborn baby’s brain
• changes in the brain in response to learning
• changes in the size of the brain

An enriched environment can best be explained as:

• an environment that provides adequate amounts of food and water, and a safe living space.
• an environment that has limited brain stimulation and lots of social stimulation.
• an environment which encourages social interaction and provides significant opportunity for brain stimulation.
• an environment with significant opportunities for brain stimulation, limited opportunities for social interaction and few opportunities for safety.

A process whereby the synaptic connections in the brain that are frequently used are preserved, and those that are not are lost.

• neurotoxicity
• brain pruning 
• synaptic pruning 
• brain tango 

Carol is 7 years old and has had a hemispherectomy (The removal of one hemisphere of the brain) Carol's brain will: 

• Repair slower than an adults
• Repair faster than an adults
• Repair at the same rate as an adults
• No Idea

Someone with brain damage to the Broca's area may no longer be able to speak. According to neuroplasticity theory, why might the person recover their speech?

• Broca's areas grows back

• More white matter develops around the neurons in this area

• new neurons develop linking together the already established neural network

• there is an increase in the grey matter in the Broca's compared to before the accident

Which of the following defines critical period?

• a period during someone's development in which a particular skill or characteristic is believed to be most readily acquired.

• a period during someone's development in which a particular skill or characteristic must be acquired otherwise the skill will never develop at all.

• a period during someone's development in which a particular skill or characteristic cannot be readily acquired.
