d' index  

Définition

  • In signal detection theory applied to recognition, the index is used to assess the subject's ability to distinguish old (studied) from new items. It is therefore an index of discrimination corresponding to the distance between the mean of the distribution of familiarity of old items minus that of new items, divided by the standard deviation of the distribution of new items. The higher the index, the more old items are distinguished from new items.
