Origins and the Scientific Development of Psychology
Trace psychology's movement from philosophical questions and introspection toward competing scientific approaches and cumulative 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
Early introspection attempted systematic self-observation but faced difficulties of objectivity, verification and replicability.
Exam cue: Place an approach in its historical and methodological context.
Concept 2
Behaviourism, cognitive science, biological methods and later methodological pluralism changed what counted as acceptable psychological evidence.
Exam cue: Judge scientific status through testability, objectivity, control and replication.
Concept 3
Psychology develops through theory, empirical testing, criticism, replication and revision rather than a simple replacement of old ideas.
Exam cue: Avoid assuming that newer evidence automatically makes every earlier concept worthless.
Targeted study blocks
Multi-board knowledge
Secure the shared psychological core
Learn how the major approaches emerged and how scientific criteria apply to psychological claims across historical and contemporary contexts.
Scientific reasoning
Use evidence before reaching a judgement
Evaluate scientific status by applying explicit criteria to a theory or method rather than attaching a global label to the whole discipline.
Risk pitfalls and guardrails
Describing a timeline without explaining why methods changed.
Guardrail: Do not memorise a study as an isolated story or assume that one board's named research and option choices apply nationally.
Equating laboratory control with complete objectivity.
Guardrail: Do not memorise a study as an isolated story or assume that one board's named research and option choices apply nationally.
Treating psychology as either wholly scientific or wholly unscientific.
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
Introspection
Introspection is the systematic examination and reporting of conscious experience.
Empiricism
Empiricism grounds claims in observable or measurable evidence.
Falsifiability
A falsifiable explanation makes predictions that evidence could show to be wrong.
Paradigm
A paradigm is a shared framework of assumptions, questions and methods.
Replication
Replication tests whether a finding can be reproduced under specified conditions.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
