	''The persuasive power of brain images has captivated scholars in many disciplines. Like others, we too were intrigued by the finding that a brain image makes accompanying information more credible (McCabe & Castel in Cognition 107:343-352, 2008). But when our attempts to build on this effect failed, we instead ran a series of systematic replications of the original study—comprising 10 experiments and nearly 2,000 subjects. When we combined the original data with ours in a meta-analysis, we arrived at a more precise estimate of the effect, determining that a brain image exerted little to no influence. The persistent meme of the influential brain image should be viewed with a critical eye.''		''The persuasive power of brain images has captivated scholars in many disciplines.

== Introduction ==
Iels ont voulu reproduire la 3e expérience de l'article de McCabs et Castel ([[Seeing is believing: The effect of brain images on judgments of scientific reasoning|2008]]), qui était celle qui avait montré la plus grande taille d'effet du papier (''d'' = 0.40).

Globalement, l'expérience montrait qu'il y avait une différence de jugement si l'on montrait aux gens un article traitant

== Method ==
La question de recherche qui guide ce travail est donc : Quelle est la taille d’effet réelle liée à la 3e xp de MacCabe et Castel (2008)

Globalement iels ont fait un design 2x2 intersujets avec :
* La présence (vs absence) d'image de cerveau montrant l'activité du lobe frontal
* La présence (vs absence) d'une critique le contenu de l'article

== Résultats ==

Exp 1-5 (3 et 5 sont en ligne)
*VI: image (cerveau) // pas d’image
*VD: ''Do you agree or disagree with the conclusion that brain imaging can be used as a lie detector?''
*R: pas d’effet

Exp 6-10
*VI:
**image (cerveau) // pas d’image
** paragraphe critique d’un expert // pas de paragraphe critique
*VD: ''Do you agree or disagree with the conclusion that brain imaging can be used as a lie detector?''
* R: Effet seulement pour Exp7

Meta analyse
* R: d = 0.07 (au lieu de ''d'' = 0.43 annoncé)
