How do we know what an experiment shows?

Methods, evidence and reproducibility

Topic guide · Perception, attention and action / Methods, evidence and reproducibility

How does attention shape what we notice?

Move from selection and perceptual tasks to competing accounts of attention, measurement and the separate question of awareness.

Topic guide · Evolution and other minds / Cells, circuits and brains / Methods, evidence and reproducibility

What can—and cannot—we learn by comparing brains across species?

Move from brain size and proportional scaling to cellular development and task-specific behaviour, without turning the comparison into a ranking of intelligence.

Topic guide · Mental health and intervention / Methods, evidence and reproducibility

How is evidence for depression treatment assessed?

Connect the clinical question, comparison, outcome and guideline judgement without choosing treatment for an individual.

Topic guide · Computational approaches and AI / Cells, circuits and brains / Methods, evidence and reproducibility

Connect modelling goals, simplified neuronal mechanisms, spike data and fitting exercises, with an optional route into network models.

Topic guide · Consciousness and philosophy / Reasoning and decisions / Methods, evidence and reproducibility

Analyse the gap between an experimental task, a neural prediction and a philosophical conclusion about control.

Topic guide · Methods, evidence and reproducibility / Reasoning and decisions

When can a study support a causal explanation?

Separate an observed relationship from a specified intervention contrast and inspect the assumptions connecting them.

Topic guide · Personality and individual differences / Development across life / Methods, evidence and reproducibility / Evolution and other minds

How do genes and environment influence behaviour?

Interpret family and twin comparisons, population heritability and developmental experiments without turning them into percentages of a person or claims of inevitable outcomes. This route explains foundational inference, not personal genetic risk or modern genome-wide prediction.

Topic guide · Social and cultural behaviour / Evolution and other minds / Methods, evidence and reproducibility

How do group identities shape collective behaviour?

Compare identity, norms, incentives and authority as possible explanations, then examine the move from research findings to policy proposals.

Topic guide · Cells, circuits and brains / Methods, evidence and reproducibility

How can we study what a human brain is doing?

Compare measurement approaches, experimental contrasts and interpretational limits before following a specialist brain-imaging or connectivity route.

Topic guide · Evolution and other minds / Consciousness and philosophy / Methods, evidence and reproducibility

How can we investigate consciousness in other animals?

Compare evidence about experience with evidence about particular behavioural abilities, while making alternative explanations explicit.

Topic guide · Reasoning and decisions / Methods, evidence and reproducibility

How should we reason with uncertain information?

Build a probability model, condition on information and expose independence assumptions before comparing formal rules with human judgements.

Topic guide · Emotion, motivation and sleep / Cells, circuits and brains / Methods, evidence and reproducibility

How are sleep and biological clocks studied?

Connect timing, light cues and experimental measurements while keeping sleep and circadian questions distinct.

Topic guide · Emotion, motivation and sleep / Mental health and intervention / Methods, evidence and reproducibility

How do researchers study stress and health?

Separate a stressor, a measured response and an outcome, then examine the study design linking them.

Topic guide · Consciousness and philosophy / Methods, evidence and reproducibility / Computational approaches and AI

How can competing theories of consciousness be tested?

Distinguish a named theory, a particular prediction, a measurement and the interpretation of a result.

Topic guide · Evolution and other minds / Social and cultural behaviour / Methods, evidence and reproducibility

How can evolutionary explanations of human behaviour be tested?

Separate mechanism, development, ancestry and possible function, then ask which comparative observations could distinguish rival accounts.

Topic guide · Personality and individual differences / Methods, evidence and reproducibility

What do intelligence test scores measure?

Distinguish a performance, a score, a construct and a causal explanation when reading intelligence claims.

Topic guide · Learning, memory and education / Methods, evidence and reproducibility

What can learning analytics actually tell an educator?

Connect recorded learning traces to a defensible educational question, distinguishing measurement, prediction and evidence of improvement.

Topic guide · Methods, evidence and reproducibility / Mental health and intervention

What makes a therapy trial informative?

Work through comparison, assignment, outcomes, masking and generalisation using an original study-design exercise.
