Journal ArticleDOI
Improving fluid intelligence with training on working memory
TL;DR: It is concluded that it is possible to improve Gf without practicing the testing tasks themselves, opening a wide range of applications.
Journal ArticleDOI
The concurrent validity of the N-back task as a working memory measure
TL;DR: The data suggest that the N-back task is not a useful measure of individual differences in WM, partly because of its insufficient reliability, but the task seems to be useful for experimental research in WM and also well predicts inter-individual differences in other higher cognitive functions, such as fluid intelligence, especially when used at higher levels of load.
Journal ArticleDOI
The Relationship between N-Back Performance and Matrix Reasoning--Implications for Training and Transfer.
Susanne M. Jaeggi,Barbara Studer-Luethi,Barbara Studer-Luethi,Martin Buschkuehl,Yi-Fen Su,John Jonides,Walter J. Perrig +6 more
TL;DR: In this article, the authors explored the underlying mechanisms of transfer effect in two studies, and evaluated the transfer potential of a single n-back task, and showed that training on a single N-Back task yields the same improvement in fluid intelligence as training on dual N-back tasks, but that there should be less transfer to working memory capacity.
Journal ArticleDOI
Processing of Temporal Unpredictability in Human and Animal Amygdala
Cyril Herry,Dominik R. Bach,Fabrizio Esposito,Francesco Di Salle,Walter J. Perrig,Klaus Scheffler,Andreas Lüthi,Erich Seifritz +7 more
TL;DR: It is shown that unpredictability per se is an important feature of the sensory environment influencing habituation of neuronal activity in amygdala and emotional behavior and that regulation of amygdala habituation represents an evolutionary-conserved mechanism for adapting behavior in anticipation of temporally unpredictable events.
Journal ArticleDOI
Propositional and situational representations of text
Walter J. Perrig,Walter Kintsch +1 more
TL;DR: In this article, two informationally equivalent texts were constructed which described a fictitious town, emphasizing its spatial layout, and subjects were able to recall the texts quite well, while showing little ability to use the information they had acquired to make inferences about spatial relations in the town which had not been directly stated in the text.
