“…Several studies reported modulations of population activity in human and monkey early visual cortex, which were largely decoupled from cortical stimulus representations but linked to behaviorally relevant events (Cardoso et al 2012;Choe et al 2014;de-Wit et al 2012;Donner et al 2008Donner et al , 2013Jack et al 2006;Hsieh and Tse 2009;Sirotin and Das 2009;Swallow et al 2012;Wilke et al 2006). Specifically, several human fMRI studies reported retinotopically widespread modulations in V1 during perceptual reports in MIB Hsieh and Tse 2009), bistable motion binding (de-Wit et al 2012), and visual discrimination tasks (Choe et al 2014).…”

“…According to Hunt and Elliot (1980), in the context of mixed study lists, the visual irregularity of LF-OD words would induce participants to perform a more detailed analysis of their orthographic properties, which in turn offsets any additional processing advantage induced by the ABE. Interestingly, Kirchhoff, Schapiro, & Buckner (2005) reported that the recognition of orthographically distinctive words activated occipital and parietal regions more than did orthographically common words, and Swallow, Makovski and Jiang (2012) found that the detection of auditory targets enhanced activity in the primary visual cortex. This partial overlap in the neural underpinnings of the ABE and the ODE may potentially account for the observed redundancy in their memory consequences.…”

Limits to the attentional boost effect: the moderating influence of orthographic distinctiveness

The Attentional Boost Effect (ABE) refers to the counter-intuitive finding that the detection of infrequent targets in a divided-attention (DA) condition enhances memory of images co-occurring with targets (as compared with images co-occurring with distractors; Swallow & Jiang Cognition, 115, 118-132, 2010). Previous studies have shown that the ABE also applies to verbal materials (words; Spataro, Mulligan, & Rossi-Arnaud Journal of Experimental Psychology: Learning, Memory, and Cognition, 39, 1223-1231) and documented an important moderating factor, word frequency-the ABE was robust for high-frequency words, but small or non-significant for low-frequency words (Mulligan, Spataro, & Picklesimer Journal of Experimental Psychology: Learning, Memory, and Cognition, 40, 1049-1063, 2014). The present experiment tested the predictions of the early-phase-elevated-attention hypothesis of the ABE by manipulating the orthographic distinctiveness of the to-beremembered words. Results revealed that the ABE was significant for low-frequency words with common orthographic features, but not for low-frequency words with rare orthographic features. As a consequence, the orthographic distinctiveness effect (ODE) was eliminated in the DA condition. These findings are in line with the proposal that the ABErelated attentional enhancement occurs during an early phase of stimulus perception and comprehension, as well as with the proposal that the ODE is mediated by high-level, attention demanding comparative processes.

“…In line with the results of other studies using visual/auditory oddball tasks, a cluster of regions were more active after the presentation of target than distractor stimuli, including: the middle and superior frontal gyri of the left hemisphere, the anterior and posterior regions of the right cingulate cortex, the basal ganglia, the thalamus and the insula bilaterally, and the brainstem in the vicinity of the locus coeruleus (LC). Importantly, Swallow, Makovski, and Jiang (2012) found that the presentation of auditory targets led to enhanced activity in the primary visual cortex, whereas the presentation of visual tar gets increased activity in the primary auditory cortex. These find ings suggest that the detection of goal-relevant targets produces cross-modal facilitations in the perceptual processing of back ground stimuli temporally co-occurring with them (Swallow & Jiang, 2013).…”

“…Regarding the neural underpinnings of the ABE, an fMRI study showed that the detection of targets induces broad, temporally locked enhancements in cortical regions that are not directly in volved in their processing (Swallow, Makovski, & Jiang, 2012). Participants in these experiments encoded faces, scenes or scram bled images and simultaneously pressed a button whenever a tone of a predefined pitch was presented over headphones (or a square of a given color appeared on the screen).…”

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.
