Abstract

This article describes the data collected in four experiments presented in the paper "Visual working memory capacity is limited by two systems that change across lifespan" [1]. The data includes behavioural results from a sample of 397 healthy participants performing a visual working memory span task in which they had to maintain the orientations of items presented to the left, right, or both visual hemifields. It also includes a simulation of experimental data for a number of possible scenarios. The repository [2] encompasses individual raw data files, a Python preprocessing script used for filtering raw data and the resulting dataset, an R script used to carry out the statistical analysis of the preprocessed data as well as an R script used for the simulations reported in the original paper. Finally, the repository includes an R generated analysis report, containing results of statistical tests and related visual materials, as well as the results of the simulation.
