  2. Generalisability Can the findings be GENERALISED to the real world? Consider where the research was conducted. Are artifical/contrived laboratory conditions anything like the real world? (ECOLOGICAL VALIDITY) What TASK were ppts asked to do? Was it something they would do in their everyday lives? (MUNDANE REALISM) Was the sample representative of the target population? Can the findings be generalised to the target population?

  3. Reliability • Are the results consistent? • Was the procedure standardised so that replication is possible? • Has the research been replicated?

  4. Application • Is the research useful? • Are there any obvious applications? • Who will benefit from the findings?

  5. Validity • Does the study have INTERNAL VALIDITY? • Can you see any other possible explanation for the findings? • Were extraneous variable controlled? • Has the research measured what it set out to measure or has it accidentally measured something else? • Does it have ecological validity? • Does it have population validity?

  6. Ethics • Does the research adhere to the ethical guidelines laid down by the BPS or APS? • Deception? De-brief? • Right to withdraw? • Informed consent? • Protection from harm? • Privacy protected • Was the researcher Competent?
