Temporal gradients for media-mediated memory : Italian norms

Temporal gradient (TG), i.e., differential recallof recent and old memories, is a well known feature ofamnesia. A recent study provided evidence of a classicalTG for media-mediated events in elderly healthy people,showing that they recall remote events significantly betterthan recent ones, while a reverse TG, i.e., better recall ofmore recent events, was demonstrated in younger normalsubjects. In the present study we present normative datawhich, using the same test, allow evaluation of TG in singlecases and their qualification as classical or reverse. Thenormative procedure was also applied to a small sample ofsubjects with probable Alzheimer's disease or mild cognitiveimpairment. Norms for TG may be helpful not only toassess healthy people's performance, but also to judge anyapparent TG in pathological subjects.
