“…Converging evidence comes from studies using eventrelated potentials (ERPs), which highlight how rapidly particular effects arise. Telling et al [5] used the same paradigm as Moores et al [4] and measured ERPs. They documented effects of semantic distractors on the so-called N2pc component.…”

Actions taking place in the environment are critical for our survival. We review evidence on attention to action, drawing on sets of converging evidence from neuropsychological patients through to studies of the time course and neural locus of action-based cueing of attention in normal observers. We show that the presence of action relations between stimuli helps reduce visual extinction in patients with limited attention to the contralesional side of space, while the first saccades made by normal observers and early perceptual and attentional responses measured using electroencephalography/event-related potentials are modulated by preparation of action and by seeing objects being grasped correctly or incorrectly for action. With both normal observers and patients, there is evidence for two components to these effects based on both visual perceptual and motor-based responses. While the perceptual responses reflect factors such as the visual familiarity of the action-related information, the motor response component is determined by factors such as the alignment of the objects with the observer's effectors and not by the visual familiarity of the stimuli. In addition to this, we suggest that action relations between stimuli can be coded pre-attentively, in the absence of attention to the stimulus, and action relations cue perceptual and motor responses rapidly and automatically. At present, formal theories of visual attention are not set up to account for these action-related effects; we suggest ways that theories could be expected to enable action effects to be incorporated.

“…Targets are identified more effectively when they appear within repeated spatial configurations of distractors compared with novel contexts. Electrophysiological recordings during contextual cueing experiments have revealed modulation of targetselection mechanisms (Johnson et al, 2007;Chaumon et al, 2008Chaumon et al, , 2009Schubö, 2009, 2010;Telling et al, 2010), although findings have not been entirely consistent and studies have not always controlled adequately for eye movements. Furthermore, because the target appears embedded within distractors, it is not possible to test for perceptual modulations unambiguously.…”

Human perception is highly flexible and adaptive. Selective processing is tuned dynamically according to current task goals and expectations to optimize behavior. Arguably, the major source of our expectations about events yet to unfold is our past experience; however, the ability of long-term memories to bias early perceptual analysis has remained untested. We used a noninvasive method with high temporal resolution to record neural activity while human participants detected visual targets that appeared at remembered versus novel locations within naturalistic visual scenes. Upon viewing a familiar scene, spatial memories changed oscillatory brain activity in anticipation of the target location. Memory also enhanced neural activity during early stages of visual analysis of the target and improved behavioral performance. Both measures correlated with subsequent target-detection performance. We therefore demonstrated that memory can directly enhance perceptual functions in the human brain.

“…Nontarget objects which are physically dissimilar but semantically linked to current targets can attract attention during visual search (e.g., Moores, Laiti, & Chelazzi, 2003;Belke, Humphreys, Watson, Meyer, & Telling, 2008; see also Telling, Kumar, Meyer, & Humphreys, 2010, for ERP evidence). Along similar lines, images of real-world visual objects that match the current search target category can capture attention even when they are presented at task-irrelevant locations (Wyble, Folk, & Potter, 2013), indicating that information about object categories can be 23 encoded rapidly and can affect the deployment of attention in a task-set contingent fashion (see also Castelhano, Pollatsek, &Cave, 2008, andMaxfield, Stadler, &Zelinsky, 2014, for evidence that the typicality of target objects in terms of their category can affect visual search performance).…”
