Does Boundary Extension Need Attention?

When we look at a picture, we tend to remember it by enriching the constructed mental representation with elements not present but probable outside the current view. The tendency to remember the perceived view with a broader scope is known as boundary extension (BE). Does BE benefit from paying reduced attention to the picture? While attention plays a central role in memory, only a few studies to date have investigated this question in the field of BE. In this research, participants completed a BE task in single- and dual-task conditions. The results indicate that BE is eliminated when the attention is divided on the onset of scene construction. We therefore discuss the role of attention in BE.
