Document Summary
Week 3: older children and adults have representational flexibility, they realise that a picture could stand for more than one things and typically answer yes to those questions, younger children have more of a hard time doing so. If young children understand that a picture refers to real world objects, they should select the object whisk. Baseline matching: make sure you are comparing what you want to compare, early studies showed that face recognition improved with age. Always ask if your stimuli allow you to make a comparison. If adults are just faster overall or have better memory overall, we may conclude a difference when there isn"t one or it is not the one we are interested in. So often people want to compare performance on a baseline condition, with the condition we are interessted in: however, if the sample has a restricted range of scores the correlation between the groups will be reduced.
