only in childhood

only in response to medication

throughout life
4.
What happens in the circuit formation stage of development of the nervous system?
a)
Correct connection of each neuron is necessary.
b)
Neurons grow to their targets and form connections.
c)
Neurons continue dividing around a central neuron and form a circuit.

5.
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?
a)
Jade’s parents were too old for their brains to form any new neurological pathways when they moved to Australia.
b)
Adult brains display less plasticity for language acquisition than a young child’s brain.
c)
Adult brains display more plasticity for language acquisition than a young child’s brain.
d)
The development of brain plasticity means that it is impossible to learn a new language after childhood.
6.
Which statement is true about developmental plasticity?
a)
It is a typical feature of childhood.
b)
It is evident in both a child’s brain and an adult’s brain.
c)
It occurs only in people recovering from serious brain injuries.
d)
It is more evident in some areas of the brain than in other areas of the brain.
7.
The development of neural pathways in response to new experiences is known as:
a)
adaptive plasticity, which occurs in episodes of amnesia.
b)
adaptive plasticity, which occurs only in elderly people.
c)
adaptive plasticity, which occurs only in early childhood.
d)
developmental plasticity, which occurs only in early childhood.
8.
What happens to the corpus callosum during adolescence?
a)
It thickens and there is an increase in connections between the two hemispheres.
b)
It thins out as more synapses are pruned.
c)
It becomes more active.
d)
It thickens and there is an increase in connections between the brain and the peripheral nervous system
9.
Kristen is 15 and often becomes very emotional and cries in response to stress. Liana is 25 and can deal with stress calmly and rationally. Which structure of the brain has not yet developed in Kristen’s brain, but has in Liana’s?
a)
cerebellum
b)
amygdala
c)
corpus callosum
d)
frontal lobe
10.
What does the term ‘adaptive plasticity’ refer to?
a)
changes in the brain in response to hormones
b)
changes in a newborn baby’s brain
c)
changes in the brain in response to learning
d)
changes in the size of the brain
11.
An enriched environment can best be explained as:
a)
an environment that provides adequate amounts of food and water, and a safe living space.
b)
an environment that has limited brain stimulation and lots of social stimulation.
c)
an environment which encourages social interaction and provides significant opportunity for brain stimulation.
d)
an environment with significant opportunities for brain stimulation, limited opportunities for social interaction and few opportunities for safety.
12.
Yu Yan is recovering from a brain injury caused by a stroke. She now finds it difficult to speak and, when she does talk, her speech is slow and poorly articulated. What is Yu Yan likely to be suffering from?
a)
synaesthesia
b)
spatial neglect
c)
Broca’s aphasia
d)
Wernicke”s aphasia
13.
Monty suffers from Wernicke’s aphasia. As a result, it is likely that:
a)
he is consciously aware of his inability to communicate.
b)
he produces speech that contains nouns and verbs only.
c)
his ability to read is unaffected.
d)
he is able to speak fluently.
14.
Select the independent and dependent variables used in Rosenweig, Bennet, & Diamond’s 1972 study:
a)
the environment the rats were placed in (enriched, deprived or the control); changes in brain size
b)
being in an enriched environment; being in a deprived environment
c)
increased brain size; increased neuron activity in the cerebral cortex
d)
being alone; being with other rats
15.
Sally is home-schooled and, on a typical day, interacts mostly with her mother. Sally also finds her days quite repetitive; she is rarely exposed to new information. Sally’s brother Romulus attends the local primary school
and gets to play with friends each day and is constantly learning about new topics. From this information, select the option below that best describes Sally and Romulus’ environments:
