Reliability
:-) Standardised procedures- (lab ex) same video, same questions, same questionnaire, same time.

External Validity
:-( Lacks mundane realism as would not be asked to judge speed of cars on a video clip in real life. Would not be asked a week later if you saw any broken glass. 4/7 crashes in the videos in exp 1 were staged.

Sampling
:-) 40 (exp 1) 150 (exp 2) :-( All students (don't drive?)-same age, opportunist sample (bias)- similar people not a range.
