The demands on working memory are heightened mainly by increasing the number of stimuli (butterflies) that the client must retain and update.The three types of task (n-back, running, keep-track) occur one after the other across the different levels; at the highest levels they are combined to form new task variants.These feature the methodological advancement of estimating interindividual covariation and experimental effects on mean updating measures simultaneously.The modeling results imply that WMC is a strong predictor of WMU skills in general, although some component processes-in particular, substitution skills-were independent of WMC.
Hence, we sought to develop a WM updating task, which we termed the selective updating of sentences (SUS) task, which taps the ability to constantly update sentences.
Hence, the reported predictive power of WMU measures may rely largely on common WM functions also measured in typical WMC tasks, although substitution skills may make an independent contribution to predicting higher mental abilities.
AB - Working memory updating (WMU) has been identified as a cognitive function of prime importance for everyday tasks and has also been found to be a significant predictor of higher mental abilities.
As the level increases both the number of butterflies on the screen and their speed also increase.
In addition, the timing of the questions becomes increasingly unpredictable as the client progresses through the levels.
