Document Summary

Internal degree to which experiment supports the causal conclusion. External degree to which results can be generalized. Placebo effect change in behaviour or reaction due to your expectations (thinking a drug will work can change your behaviour because you expect something will happen) Darragh el al. (2015) itch reduced if participants thought they were getting antihistamine cream. Kaptchuk (2014) migraine pain reduced even if you take a pill named placebo (even if you know the drug isn"t going to effect you, the placebo effect can still effect) Cues in experiment convey hypothesis to participants. Expecting if it goes better/worse will make it happen the way you think it will. Best way to protect this experiment bias is double-blind procedure . What do lab experiment tell us about everyday life: not much, it gives us predictions what may happen in the future.
