History repeating itself: Arnaud's case of pathological déjà vu.
International audience; We present a translation of Arnaud's (1896) case report of Patient Louis, a case he describes as having a pathological form of déjà vu.

We offer a contemporary analysis of Louis an…

Short-term memory predictions across the lifespan: monitoring span before and after conducting a task.
Our objective was to explore metamemory in short-term memory across the lifespan. Five age groups participated in this study: 3 groups of children (4-13 years old), and younger and older adults. We used a three-phase task: prediction-span-postdiction. For prediction and postdiction phases, participants reported with a Yes/No response if they could recall in order a series of images. For the span task, they had to actually recall such series. From 4 years old, children have some ability to monitor their short-term memory and are able to adjust their prediction after experiencing the task. However, accuracy still improves significantly until adolescence. Although the older adults had a lower …
