Perceptual load and attentional boost: a study of their Interaction.
Journal of Experimental Psychology: Human Perception and Performance, 2013Co-Authors: Khena M. Swallow, Yuhong V. JiangAbstract:Increasing attention to an item typically interferes with the ability to process other concurrent information. The attentional boost effect, however, appears to contradict the ubiquity of dual-Task interference. Rather, detecting a target item for one Task boosts memory for a currently presented, but unrelated background scene. To account for the apparent discrepancy between dual-Task interference and attentional boost, we present and test the dual-Task Interaction Model. This Model states that dual-Task interference occurs at multiple stages of processing, but the decision that an item is a target triggers a cross-Task enhancement to perceptual processing. Consistent with this Model, this study shows that targets, but not perceptually similar distractors, trigger the attentional boost effect. In addition, the attentional boost effect is unperturbed when the perceptual load of target detection increases. The effect can also occur for Task-irrelevant background images. Consistent with the dual-Task Interaction Model these data clearly tie the attentional boost effect to the decision that an item is a target. They also suggest that this decision can rapidly boost the availability of perceptual resources. (PsycINFO Database Record (c) 2013 APA, all rights reserved). Language: en

Attentional Load and Attentional Boost: A Review of Data and Theory
Frontiers in Psychology, 2013Co-Authors: Khena M. Swallow, Yuhong V. JiangAbstract:Both perceptual and cognitive processes are limited in capacity. As a result, attention is selective, prioritizing items and Tasks that are important for adaptive behavior. However, a number of recent behavioral and neuroimaging studies suggest that, at least under some circumstances, increasing attention to one Task can enhance performance in a second Task (e.g., the attentional boost effect). Here we review these findings and suggest a new theoretical framework, the dual-Task Interaction Model, that integrates these findings with current views of attentional selection. To reconcile the attentional boost effect with the effects of attentional load, we suggest that temporal selection results in a temporally specific enhancement across modalities, Tasks, and spatial locations. Moreover, the effects of temporal selection may be best observed when the attentional system is optimally tuned to the temporal dynamics of incoming stimuli. Several avenues of research motivated by the dual-Task Interaction Model are then discussed.

The attentional boost effect in schizophrenia.
Journal of Abnormal Psychology, 2014Co-Authors: Clelia Rossi-arnaud, Pietro Spataro, Daniele Saraulli, Neil W. Mulligan, Antonio Sciarretta, Valeria R. S. Marques, Vincenzo CestariAbstract:: The present study reports 2 experiments examining the Attentional Boost Effect (ABE) in schizophrenic patients and matched healthy controls, using visual and verbal materials. The ABE refers to the surprising finding that, in a divided attention condition, images and words encoded with targets are remembered better than images and words encoded with distractors. Unlike controls (who showed the typical ABE), schizophrenic patients reported no memory advantage for stimuli presented together with targets in the divided attention condition. On the other hand, the interference effect on the recognition of stimuli presented with distractors was not exacerbated in patients (as compared with controls). In line with the dual-Task Interaction Model proposed by Swallow and Jiang (2013), the absence of a significant facilitation indicates that schizophrenic patients have a deficit in the process of attentional enhancement triggered by target detection. A number of neural mechanisms potentially underlying this impairment are discussed, as well as implications for the characterization of the attentional deficits involved in schizophrenia.
