A group of adults is participating in a study where they are learning to associate different coloured lights with specific tones. Initially, participants struggle to remember which light corresponds to which tone. After several days of training, they show significant improvement in their ability to accurately identify the tone associated with each light. The researchers are interested in how synaptic plasticity is involved in this learning process.
b. Explain how ‘sprouting’ and ‘pruning’ modify connections between neurons during this learning process.

In this unit students investigate the contribution that classical and contemporary research has made to the understanding of the functioning of the nervous system and to the understanding of the biological, psychological and social factors that influence learning and memory. Students examine how the human nervous system enables a person to interact with the world around them and explore how stress may affect a person’s psychological functioning. Students investigate how mechanisms of learning and memory lead to the acquisition of knowledge and the development of new and changed behaviours. A student-designed scientific investigation involving the generation of primary data related to mental processes and psychological functioning may be undertaken in either Unit 3 or Unit 4, or across both Units 3 and 4, and is assessed in Unit 4 Outcome 3.
In this area of study students explore the role of different subdivisions of the nervous system in enabling a person to integrate, coordinate and respond to internal and external stimuli. Students examine neurotransmitters and neuromodulators in the transmission of neural information. They investigate stress as a psychobiological process and consider the ways in which stress can affect psychological functioning. Students explore models that describe stress and consider strategies for coping with stress and improving mental wellbeing.
synaptic plasticity – resulting from long-term potentiation and long-term depression, which together act to modify connections between neurons (sprouting, rerouting and pruning) – as the fundamental mechanism of memory formation that leads to learning
