Visual Working Memory Represents a Fixed Number of Items Regardless of Complexity

摘要: Does visual working memory represent a fixed number of objects, or is capacity reduced as object complexity increases? We measured accuracy in detecting changes between sample and test displays found that estimates dropped increased. However, these apparent reductions were strongly correlated with increases sample-test similarity (r= .97), raising the possibility change detection was limited by errors comparing test, rather than items maintained memory. Accordingly, when low, for even most complex objects equivalent to estimate simplest .88), suggesting represents regardless complexity. Finally, correlational analysis suggested two-factor model ability, which resolution representations correspond distinct dimensions ability.
