Memory & Cognition 2002, 30 (3), 325-339
 

Summary: Memory & Cognition
2002, 30 (3), 325-339
There is growing consensus that the human attention sys-
tem is subserved by separate subsystems, or at least by a
broad anatomical network in which different subtasks are
mediated by different brain areas (e.g., Buchel & Friston,
1997; Knight, 1997; LaBerge, 1997; Olshausen, Anderson,
& Van Essen, 1993; Posner & Petersen, 1990; Rushworth,
Nixon, Renowden, Wade, & Passingham, 1997). Although
a number of different theories have been proposed, there is
widespread agreement that visual perceptual attention is
mediated by a posterior system that includes the visual
cortex, much of the posterior parietal cortex, the pulvinar,
and the superior colliculus (e.g., Desimone & Duncan,
1995; Olshausen et al., 1993; Posner & Petersen, 1990). In
contrast, executive or decisional (i.e., conscious) attention
is thought to be mediated by an anterior system that in-
cludes the anterior cingulate, the prefrontal cortex, and per-
haps the basal ganglia and the pulvinar (Ashby, Alfonso-
Reese, Turken, & Waldron, 1998; Ashby, Isen, & Turken,
