“…Recordings during target processing reveal modulation of early visual potentials, but also raise the possibility that some of the modulatory mechanisms may differ from those arising from perceptual cues (Summerfield et al 2011;Patai et al 2012;Doallo et al 2012). For instance, contrary to what is observed during visual spatial cueing (Leblanc et al 2008;Seiss et al 2009;Brignani et al 2010;Schankin and Schubo 2010), the N2PC potential related to detecting a target within a visual search array is reliably attenuated by memory cues (Doallo et al 2012;. fMRI studies show that memory cues trigger activity in the hippocampus as well as in dorsal frontoparietal areas involved in visual spatial attention (Summerfield et al 2006;.…”

and KeywordsSelective attention is essential for all aspects of cognition. Using the paradigmatic case of visual spatial attention, we present a theoretical account proposing the flexible control of attention through coordinated activity across a large-scale network of brain areas. It reviews evidence supporting top-down control of visual spatial attention by a distributed network, and describes principles emerging from a network approach. Stepping beyond the paradigm of visual spatial attention, we consider attentional control mechanisms more broadly. The chapter suggests that topdown biasing mechanisms originate from multiple sources and can be of several types, carrying information about receptive-field properties such as spatial locations or features of items; but also carrying information about properties that are not easily mapped onto receptive fields, such as the meanings or timings of items. The chapter considers how selective biases can operate on multiple slates of information processing, not restricted to the immediate sensory-motor stream, but also operating within internalized, short-term and long-term memory representations. Selective attention appears to be a general property of information processing systems rather than an independent domain within our cognitive make-up.

“…Consistent results were also found under RSVP (rapid serial visual presentation) paradigms. When participants were focusing on a central letter stream, the spatially irrelevant flanking distractors still captured attention when they were in the same color as the central targets (Brignani, Lepsien, & Nobre, 2010;Leblanc, Prime, & Jolicoeur, 2008). Nevertheless, a behavioral study reported that top-down spatial attention still played an important role in modulating the effect of attentional capture (Leonard, Balestreri, & Luck, 2015).…”

Top‐down spatial attention can modulate contingent attentional capture, but the underlying mechanism is still not clear. Using variants of spatial cueing paradigms, our previous event‐related potential study showed that peripheral color singleton cues with task‐relevant features captured attention (indexed by cue‐elicited N2pc) even when the targets appeared at central locations, but the magnitude of attentional capture was smaller than when the targets appeared at same peripheral locations. One reasonable explanation is that the modulation effect is due to spatial relevance of cues. However, several other confounding factors might also explain the modulation effect, such as task difficulty, spread of attentional window, and inside/outside relation between cue and attentional window. In the present study, we rearranged the relative locations between cues and targets to control these factors and to further examine whether inequivalence of attentional capture across attended and unattended locations was a common phenomenon. In two experiments, color singleton cues elicited apparent N2pc components when participants were searching for targets possessing the same color, which replicated typical findings of contingent attentional capture. More importantly, the modulation effect of top‐down spatial attention on the cue‐elicited N2pc still existed even when the factors of task difficulty (Experiment 1), spread of attentional window (Experiment 1), or inside/outside relation between cue and attentional window (Experiment 2) were controlled. These results consistently demonstrate that attentional capture by a color singleton is stronger at spatially relevant locations than at spatially irrelevant locations, suggesting an important role of spatial relevance on contingent attentional capture.

“…The N2pc represents an enhanced negativity at occipito-temporal electrodes contralateral to the hemifield of a visual candidate target object, typically emerges around 200 ms post-stimulus, is generated in retinotopic occipito-temporal cortex (Hopf et al 2000), and is associated with the allocation of spatial attention to visual objects rather than preparatory visual-spatial orienting (Brignani, Lepsien, & Nobre, 2010; Leblanc, Prime, & Jolicoeur, 2008; Seiss, Kiss, & Eimer, 2009). Thus far, virtually all N2pc studies of top-down controlled attentional target selection have investigated conditions where search templates specify target features or feature conjunctions (e.g., color, size, shape, or orientation).…”

Visual search is often guided by top-down attentional templates that specify target-defining features. But search can also occur at the level of object categories. We measured the N2pc component, a marker of attentional target selection, in two visual search experiments where targets were defined either categorically (e.g., any letter), or at the item level (e.g., the letter C) by a prime stimulus. In both experiments, an N2pc was elicited during category search, in both familiar and novel contexts (Experiment 1) and with symbolic primes (Experiment 2), indicating that even when targets are only defined at the category level, they are selected at early sensory-perceptual stages. However, the N2pc emerged earlier and was larger during item-based search compared to category-based search, demonstrating the superiority of attentional guidance by item-specific templates. We discuss the implications of these findings for attentional control and category learning.
