PSYC10003 · Mind, Brain and Behaviour 1
Introduction to Mind, Brain and Behaviour
Week 1 frames PSYC10003 as the science of the human mind, brain and behaviour studied through experimental psychology, and maps the four equally-weighted exam domains — Learning & Cognition, Behavioural Neuroscience, Sensation & Perception, and Research Methods — that each contribute 25% of the 100-item multiple-choice final exam. It introduces the three levels of analysis (behaviour, mind, brain), the bio-psycho-social approach, and the replication/credibility themes (the repliCATS IDEA protocol) that recur across the subject and underpin Assignment 1. On the exam these ideas appear as scenario items asking you to identify a level of analysis or spot a threat to a study's replicability.
What this chapter covers
- 01Psychology as an evidence-based discipline; the scientist-practitioner model
- 02Three levels of analysis: behaviour (what we do), mind (sensing/attending/remembering/feeling), brain (neural basis)
- 03The bio-psycho-social approach: biological, psychological and social influences interacting
- 04The great debates: nature vs nurture, mind vs body, universal vs culturally diverse, objective vs subjective
- 05The four equally-weighted exam strands, each 25% of the 100-item MCQ paper
- 06The replication crisis: failures to replicate; researcher degrees of freedom (optional stopping, HARKing, selective reporting)
- 07Solutions / credibility revolution: transparency, publishing replications, rewarding rigour over novelty
- 08The repliCATS IDEA protocol: Investigate → Discuss → Estimate → Aggregate (Assignment 1 grounding)
Diagnosing a non-replicating finding
- +1Identify the first flexible practice. Testing participants until significance is reached is optional stopping — deciding when to stop collecting data based on the result, which inflates the false-positive rate.
- +1Identify the second. Reporting only the measures that 'worked' is selective reporting of variables (part of the researcher-degrees-of-freedom family, alongside dropping outliers and HARKing).
- +1Level of analysis. A claim about a pose changing performance is pitched at the behaviour level (an observable action and its measurable outcome), though it is often mistakenly dressed up as a mind-level or brain-level mechanism.
- +1Solution. Any one of: pre-registration / greater transparency (committing to the analysis and stopping rule in advance), encouraging and publishing independent replications, or shifting peer review to reward rigorous, transparent, well-calibrated work over attention-grabbing results.
Key terms
- Levels of analysis
- The three complementary levels at which mind and behaviour are studied: behaviour (observable actions), mind (perception, attention, memory, thought, feeling) and brain (the neural and bodily basis of both).
- Bio-psycho-social approach
- The view that behaviour arises from biological, psychological and social influences interacting, rather than from any single cause.
- Replication
- An independent researcher reproducing a result using similar methods, to test whether a finding is a reliable pattern rather than a fluke.
- Researcher degrees of freedom
- Flexible, often undisclosed analytic choices made after seeing data — optional stopping, dropping outliers, HARKing, selective reporting — that inflate false positives and drive the replication crisis.
- repliCATS / IDEA protocol
- A structured group method for appraising a research claim's credibility: Investigate (private first estimate) → Discuss (reveal and debate) → Estimate (private revised estimate) → Aggregate (combine mathematically).
- Evidence-based discipline
- A field in which knowledge rests on empirical research that tests theories, not on intuition or authority alone.
Introduction to Mind, Brain and Behaviour FAQ
Do I need to memorise dates and researcher names for the exam?
Generally no — the exam tests findings and concepts, not names and dates directly. You should still recognise landmark work by what it showed (for example, that many published psychology results fail to replicate), because stems often describe a study and ask what it demonstrates.
What is the difference between the mind and brain levels of analysis?
The brain level concerns the physical neural and bodily machinery (neurons, structures, chemistry); the mind level concerns the psychological processes that machinery supports (perceiving, attending, remembering, feeling). The behaviour level is what is outwardly observable. A full account of a phenomenon usually needs all three.
How does the replication material connect to Assignment 1?
Assignment 1 is a team-based critical appraisal of a published study using the structured repliCATS-style IDEA protocol. The Week 1 replication-crisis content — researcher degrees of freedom, transparency, replicability — is the conceptual toolkit you apply, and it is also examinable through the Research Methods lens.
Why does this subject spend Week 1 on the 'science' of psychology?
Because psychology is an evidence-based discipline studying largely intangible constructs, how a claim was tested matters as much as the claim itself. The scientific-thinking themes introduced here recur in every strand and are the backbone of the Research Methods block worth 25% of the exam.
Exam move
Use Week 1 to build the mental scaffold you will hang the whole subject on: the three levels of analysis and the four exam strands. Make a one-line summary of each great debate and be able to place an example on the correct side. For the replication material, practise turning a described study into a diagnosis — name the researcher degree of freedom, then name the fix — because this exact reasoning reappears in the Research Methods block and in Assignment 1's repliCATS appraisal. Keep this framing sheet by you through SWOTVAC so every later topic slots into 'which strand, which level of analysis'. Confirm assessment details on Canvas.
