* P Strength is that the approach is scientific in its methods
* E Bandura’s procedure is very reliable because it can be replicated – as Bandura did, replicating the study in ’63 and ‘65. This was easy to do because of the standardised procedure (same script, same checklist categories, etc).
* This is important as the studies have been seen to be repeatable so that they are a reliable experiment to help us understand behaviour. Scientific credibility.
