Local item density modulates adaptation of learned contextual cues Visual Cognition, 16 June 2017 Efsun Annac, Markus Conci, Hermann J. M üller, & Thomas Geyer Department of Psychology + Graduate School of Systemic Neurosciences Ludwig Maximilian University of Munich Abstract : In everyday scenes, searched-for targets do not appear in isolation, but are embedded within configurations of non-target or distractor items. If the position of the target relative to the distractors is invariant, such spatial contingencies are implicitly learned and come to guide visual scanning (“contextual cueing”). However, the effectiveness of contextual cueing depends heavily on the consistency between bottom-up perceptual input and context memory: following configural learning, re-locating targets to an unexpected location within an unchanged distractor context completely abolishes contextual cueing, and gains deriving from the invariant context recover only very slowly with ...
