Abstract(s)
Attention has been usefully thought of as organized in priority maps – putative
maps of space where attentional priority isweighted across spatial regions in a
winner-take-all competition for attentional deployment. Recent work has
highlighted the influence of past experiences on the weighting of spatial
priority – called selection history. Aside from being distinct from more wellstudied,
top-down forms of attentional enhancement, little is known about the
neural substrates of history-mediated attentional priority. Using a task known
to induce statistical learning of target distributions, in an EEG study we
demonstrate that this otherwise invisible, latent attentional priority map can
be visualized during the intertrial period using a ‘pinging’ technique in conjunction
with multivariate pattern analyses. Our findings not only offer a
method of visualizing the history-mediated attentional priority map, but also
shed light on the underlying mechanisms allowing our past experiences to
influence future behavior.
