TL;DR: It is concluded that it is possible to improve Gf without practicing the testing tasks themselves, opening a wide range of applications.

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.

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.

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.

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.
