Hadjipanayi, Veronica; Ludwig, Casimir J. H.; Kent, Christopher – Cognitive Research: Principles and Implications, 2023
In many real-life contexts, observers are required to search for targets that are rarely present (e.g. tumours in X-rays; dangerous items in airport security screenings). Despite the rarity of these items, they are of enormous importance for the health and safety of the public, yet they are easily missed during visual search. This is referred to…

Shinskey, Jeanne L. – Infancy, 2012
Infants search for an object hidden by an occluder in the light months later than one hidden by darkness. One explanation attributes this decalage to easier action demands in darkness versus occlusion, whereas another attributes it to easier representation demands in darkness versus occlusion. However, search tasks typically confound these two…

Saiki, Jun; Koike, Takahiko; Takahashi, Kohske; Inoue, Tomoko – Journal of Experimental Psychology: Human Perception and Performance, 2005
The underlying mechanism of search asymmetry is still unknown. Many computational models postulate top-down selection of target-defining features as a crucial factor. This feature selection account implies, and other theories implicitly assume, that predefined target identity is necessary for search asymmetry. The authors tested the validity of…
