How valid is the data collected in each piece of research?
Students should comment on the nature of the tasks. L&P is unlike eyewitness testimony as they watch videos and then complete a questionnaire. Grant et al is unrealistic as it plays background noise through headphones however the nature of the task is more reflective of memory recall when learning.
Is the data a good reflection of memory recall in real life?
Students should comment on the lack of qualitative data to record participants true recall in L&P. Grant et al does record short answer questions but these are still coded as correct or incorrect.
Students may draw on the controls within each piece of research to increase validity.
