VCE Psychology — Unit 3
Neural Plasticity — Flashcards & Quiz
Neural plasticity is the brain's ability to change its structure and function in response to experience and injury. VCE Psychology Unit 3 distinguishes developmental plasticity (changes during early development) from adaptive plasticity (changes throughout life in response to learning or damage), and asks you to apply the concept to both learning and recovery from brain injury.
Key Points
- Neural plasticity: the brain's ability to reorganise through strengthening, weakening, pruning, or growing new neural connections.
- Developmental plasticity: shapes the young brain through synaptogenesis (making connections), synaptic pruning (removing unused connections), and myelination.
- Adaptive plasticity: ongoing response to experience throughout life — learning a skill, recovering from stroke, compensating for sensory loss.
- Long-term potentiation (LTP): repeated activation of a synapse strengthens it — the cellular basis of learning and memory.
- Sprouting: a neuron grows new branches to connect with neighbours; rerouting: signals find new pathways around damage.
- Experience-dependent plasticity: specific to what an individual does — London taxi drivers have larger hippocampi from navigation practice.
Common Mistakes to Avoid
- Claiming plasticity stops after childhood — adaptive plasticity continues throughout life.
- Confusing LTP (synapse strengthening) with LTM (long-term memory).
- Treating developmental and adaptive plasticity as completely separate — they overlap and both involve similar cellular mechanisms.
- Forgetting that plasticity can be maladaptive (e.g. chronic pain pathways strengthening).
- Missing named studies (London taxi drivers) when asked for evidence.
Exam Strategy
VCAA Unit 3 plasticity questions ask you to describe mechanisms or apply the concept to learning/recovery scenarios. Method: (1) define plasticity, (2) distinguish developmental from adaptive, (3) explain cellular mechanisms (sprouting, rerouting, LTP), (4) link to a named study or recovery scenario, (5) evaluate implications for rehabilitation.
Revision Tip
Plasticity mechanisms pair with examples — build a Revizi deck with each mechanism and a supporting study.
