Document Summary
Enhanced creativity in cannabis users: two conceptual variables: Excluded people who weren"t paying attention by making themselves seem psychopathic when answering blindingly. Excluded people who showed up to the study high. Exclusion may have impacted the construct validity and external validity of the study by not being able to generalize. Objective creativity measure (convergent thinking) remote associates test example: fox, man, peep, internal reliability - alpha coefficient of 0. 82 this tells the reader that there is a strong internal reliability. Cannabis users had more correct solutions than non users. Assumption there is no association between those two variables therefore the probability of this happening by chance is less than 5% than you can reject the assumption that there is no association. E. g. watching tv can kill you 8 different ways? rule out alternative explanations. Needs: covariance, temporal precedence, and internal validity.
