Brain Function, Plasticity, Rhythms and Evolution
Evaluate localisation and distributed function, neural adaptation, biological rhythms and evolutionary explanations using converging evidence.
How to study A-level Psychology
For every claim, identify the mechanism, supporting evidence, method, alternative explanation, practical implication and justified conclusion.
Core concepts
Concept 1
Localisation assigns functions to specialised neural systems, while distributed networks, lateralisation and communication explain coordinated performance.
Exam cue: Distinguish evidence that locates a function from evidence that merely correlates activity with a task.
Concept 2
Plasticity and functional recovery show that neural organisation changes with development, experience and injury, subject to constraints.
Exam cue: Explain the mechanism of plastic change or entrainment.
Concept 3
Circadian and other rhythms reflect endogenous pacemakers interacting with environmental cues; evolutionary accounts address inherited functional tendencies.
Exam cue: Evaluate imaging, lesion, case, sleep and comparative evidence together.
Targeted study blocks
Multi-board knowledge
Secure the shared psychological core
Use brain function, plasticity, rhythms and evolution as shared biological lenses while checking the learner's board for exact named content.
Scientific reasoning
Use evidence before reaching a judgement
Triangulate across methods, distinguish association from mechanism and balance biological explanation with task, experience and cultural context.
Risk pitfalls and guardrails
Assuming one active brain region acts alone.
Guardrail: Do not memorise a study as an isolated story or assume that one board's named research and option choices apply nationally.
Treating plasticity as unlimited recovery.
Guardrail: Do not memorise a study as an isolated story or assume that one board's named research and option choices apply nationally.
Using an adaptive story without a testable prediction.
Guardrail: Do not memorise a study as an isolated story or assume that one board's named research and option choices apply nationally.
Memory anchors
Localisation
Localisation proposes that particular neural areas make specialised contributions to function.
Lateralisation
Lateralisation is the unequal contribution of the cerebral hemispheres to some functions.
Plasticity
Plasticity is the nervous system's capacity to change structure or function with experience or damage.
Endogenous pacemaker
An endogenous pacemaker is an internal biological timing mechanism.
Zeitgeber
A zeitgeber is an external cue that entrains a biological rhythm.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
