The role of attention for context–context binding of intrinsic and extrinsic features.

Abstract

There is converging evidence that the feeling of conscious recollection is usually accompanied by the bound retrieval of context features of the encoding episode (e.g., Meiser, Sattler, & Weiβer, 2008). Recently, however, important limiting conditions have been identified for the binding between context features in memory. For example, focusing on the semantics of the stimuli during encoding eliminates binding between perceptual context features (Meiser & Sattler, 2007). In the present research, we investigated the interplay of the focus of attention during encoding and stimulus characteristics in context-context binding. In particular, it has been suggested that context features differ in the degree to which they can be regarded as intrinsic or extrinsic to the items and that intrinsic features might be given more attentional processing during encoding than extrinsic features (e.g., Ecker, Zimmer, & Groh-Bordin, 2007a). In two experiments, we manipulated the "intrinsicality" of context features to investigate whether context-context binding might be limited to features that are in the focus of processing. Multinomial modeling analyses revealed that while context-context binding was eliminated for incidentally processed extrinsic context features (Experiment 1), it was preserved for intentionally processed extrinsic context features (Experiment 2).
