Integrating spatial context learning over contradictory signals: Recency effects in contextual cueing

نویسنده

چکیده

Contextual cueing is a visual search phenomenon in which memory of global visual context guides spatial attention towards task-relevant portions of the search display. Recent work has shown that the learning processes underlying contextual cueing exhibit primacy effects; they are more sensitive to early experience than to later experience. These results appear to pose difficulties for associative accounts which typically predict recency effects; behaviour being most strongly influenced by recent experience. The current study utilizes trial sequences that consist of two contradictory sets of regularities. In contrast to previous results, robust recency effects were observed. In a second study it is demonstrated that this recency effect can be minimized, but not reversed by systematically manipulating task-irrelevant features of the search display. These results provide additional support for an associative account of contextual cueing and suggest that contextual cueing may, under some circumstances, be more sensitive to recent experience.

Contextual Cueing under Divided Attention Spatial Context Learning Survives Interference from Working Memory Load Contextual Cueing under Divided Attention Contextual Cueing under Divided Attention

The human visual system is constantly confronted with an overwhelming amount of information, only a subset of which can be processed in complete detail. Attention and implicit learning are two important mechanisms that optimize vision. This study addresses the relationship between these two mechanisms. Specifically we ask: Is implicit learning of spatial context affected by the amount of workin...

Interaction between scene-based and array-based contextual cueing.

Contextual cueing refers to the cueing of spatial attention by repeated spatial context. Previous studies have demonstrated distinctive properties of contextual cueing by background scenes and by an array of search items. Whereas scene-based contextual cueing reflects explicit learning of the scene-target association, array-based contextual cueing is supported primarily by implicit learning. In...

Contextual Cueing Effect in Spatial Layout Defined by Binocular Disparity

Repeated visual context induces higher search efficiency, revealing a contextual cueing effect, which depends on the association between the target and its visual context. In this study, participants performed a visual search task where search items were presented with depth information defined by binocular disparity. When the 3-dimensional (3D) configurations were repeated over blocks, the con...

Contextual Cueing Based on Specific and Categorical Properties of the Environment

During the analysis of a visual scene, top-down processing is constantly directing the subject's attention to the zones of interest in the scene. The contextual cueing paradigm developed by Chun and Jiang (1998) shows how contextual regularities can facilitate the search for a particular element via implicit learning mechanisms. The study presented here reports three experiments that used this ...

Local item density modulates adaptation of learned contextual cues

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 cons...
