“…On the one hand, we found that the attentional blink did not modulate the location benefit produced by a spatial cue (thus replicating Bae et al, 2018;Ghorashi et al, 2009a;2009b;2010;Zivony & Lamy, 2016). On the other hand, we found the AB to reduce the likelihood of identifying the distractor letter inside this cue (as indicated by the smaller response-compatibility effect observed during the blink) and to both delay the onset (see also, Lagroix et al, 2015) and reduce the amplitude (see also, e.g., Dell'Acqua et al, 2006;Jolicoeur et al, 2006a) of the N2pc component.…”

“…In direct contradiction with the conclusion of the foregoing studies, recent findings suggest that attentional capture (i.e., attentional shifting) is unaffected by the blink (Bae, Jung & Han, 2018;Ghorashi, Spalek, Enns, & Di Lollo, 2009a;Ghorashi, Enns, Klein, & Di Lollo, 2010;Ghorashi, Enns, Spalek, & Di Lollo, 2009b;Zivony & Lamy, 2014;. For instance, in Zivony and Lamy (2016, Exp.3), participants searched for two targets (T1 and T2), defined by their color (e.g., red) and embedded in two RSVP streams.…”

“…On the other hand, we observed a location benefit of equal magnitude inside and outside the blink, indicating that attentional capture was unaffected by the blink. The findings of Zivony and Lamy (2016, see also Bae et al, 2018;Ghorashi et al, 2009a;2009b;2010) were thus fully replicated.…”

“…To summarize, electrophysiological findings show that the N2pc is suppressed during the blink (e.g., Dell'Acqua et al, 2006;Jolicoeur et al, 2006a) and behavioral findings show that attentional shifts are intact during the blink (e.g., Bae et al, 2018;Ghorashi et al, 2009a;Zivony & Lamy, 2016). Taken together, these findings strongly suggest that the N2pc does not index attentional shifts, but processes that occur downstream to attentional shifting.…”

Dissociating between the N2pc and attentional shifting: An attentional blink study

The N2pc is routinely used as an electrophysiological index of attentional shifting. Its absence is thus taken as evidence that no shift of attention occurred. We provide evidence in contrast to this notion using a variant of the attentional blink (AB) paradigm. Two target letters, embedded in two streams of distractor letters and defined by their color, were separated by either 300 or 800 ms. The second target was preceded by a distractor frame of the same color (cue). As expected, identification of the second target was poorer at the short than at the long lag (the AB effect). The AB did not affect attentional capture by the cue, but suppressed and delayed the N2pc associated with it. This result suggests that the N2pc does not reflect attentional shifting. Instead, we conclude that the N2pc indexes the transient enhancement that occurs at the spatial focus of attention and promotes high-level processing such as identification. This conclusion calls for a reinterpretation of findings from the attentional capture literature that relied on the N2pc as an index of attentional shifting. Our results also inform contemporary models of the AB.

“…First, single-stream behavioral studies (Nieuwenstein, 2006;Nieuwenstein et al, 2005;Zivony & Lamy, 2016, Experiment 1) and N2pc studies where the target appeared only 1 from fixation (Verleger et al 2009;Akyurek et al, 2010) also reported findings supporting the disrupted-engagement account. Furthermore, many behavioral studies reported that attentional shifting is intact during the blink period (Bae et al, 2018;Ghorashi et al, 2009aGhorashi et al, , 2009bGhorashi et al, , 2010Zivony & Lamy, 2014Zivony et al, 2018a), while ERP studies reported modulations of the N2pc during the blink when no attentional shift time-locked to T2 was required, namely, when T1 and T2 were on the same side (Verleger et al, 2009), as well as when their locations were known in advance (Chennu et al, 2007).…”

Reporting the second of two targets is impaired when these appear in close succession, a phenomenon known as the attentional blink (AB). Despite decades of research, what mechanisms are affected by the AB remains unclear. Specifically, two central issues remain open: Does the AB disrupt attentional processes or reflect a structural limitation in working memory encoding? Does it disrupt perceptual processing or only post-perceptual processes? We address these questions by reviewing event-related potentials (ERP) studies of the AB. The findings reveal that the core influence of the AB is by disrupting attentional engagement (indexed by N2pc). As a consequence, while early processing (indexed by P1\N1) is spared, semantic processing (indexed by N400) and working memory (WM) encoding (indexed by P3b) are compromised: minor disruptions to attentional engagement weaken but do not eliminate semantic processing, whereas they prevent encoding in WM. Thus, semantic processing can survive the blink, whereas encoding in WM does not. To accommodate these conclusions, we suggest a Disrupted Engagement and Perception (DEaP) account of the attentional blink.
