"The capacity of visual working memory for features and conjunctions" by Steven J. Luck & Edward K. Vogel

Summary

This research paper investigates the capacity of visual working memory. The authors demonstrate that visual working memory holds approximately four objects, not individual features, meaning that it can retain a surprisingly large number of features if they are bound within a limited number of objects. This capacity is independent of verbal working memory and is not limited by perception or decision-making processes. The study's findings have significant implications for understanding how visual information is processed and stored in the brain, supporting models that emphasise the importance of integrated object representations and neural mechanisms such as oscillatory firing patterns.
