One limitation of this study, which also applies to most related studies (Aru et al, ; Fisch et al, ; Pitts, Martínez, & Hillyard, ; Pitts, Metzler, & Hillyard, ; Sergent, Baillet, & Dehaene, ; Shafto & Pitts, ), is that the observed modulations in the neural responses might just reflect trial‐by‐trial fluctuations of attention rather than the perceptual state of the observer (Navajas, Rey, & Quian Quiroga, ). In other words, the difference between the seen and unseen conditions may be due to a varying allocation of attentional resources.…”
