what are the measures, and do they address the research questions?
Common data collection methods in psychology include self-reports, observation, and psychophysiological measures. Self-reports constitute a large class of data collection methods in which the participant provides the data, either through responding to a questionnaire or interview questions, completing a test, or making some other behavioural response to an experimental task. Observation entails the researcher observing some physical attribute or behaviour in a particular context. Finally, psychophysiological measures concern the measurement of physiological responses, such as electrical activity, heart rate, or blood flow.
The Method section, as mentioned before, should contain enough information about the data collection methods, and procedures for another researcher to be able to replicate the study.
As you read the Methods section, try to place yourself in the position of the participant, and try to determine how well the data collection methods address the research questions. What kinds of measures did End et al. (2010) use to evaluate cognitive deficit? Were these measures appropriate for the study? Can you think of any other measures they should have collected?
