“…Some observations that could be thought to have some resemblance to ours were reported by Cheal and Lyon (10). Their prime stimulus produced a facilitatory effect (evaluated by the accuracy of the responses) that accrued along 50 to 100 ms.…”

“…Several studies have demonstrated that the occurrence of a visual stimulus influences the latency (1-6) and accuracy (4,(7)(8)(9)(10) of the response to another visual stimulus occurring 50-150 ms later. Latency and accuracy are respectively reduced and increased at the same or at a very close location as the first stimulus and are respectively increased and reduced at distant locations.…”

We investigated the dependency of the early facilitatory effect of a prime stimulus (S1) on the physical characteristics of the target stimulus (S2). A go/no go reaction time paradigm was used. The S1 was a gray ring and the S2s were a white vertical line, a white horizontal line, a white cross and a white small ring, all inside a white ring with the same dimensions as the S1. S1 onset-S2 onset asynchrony was 100 ms. The stimuli appeared randomly in any one of the quadrants of a monitor screen. The S2 could occur at the same position as the S1 or at a different one. We observed a strong facilitatory effect when the vertical line or the horizontal line was the go stimulus and no effect when the cross was the go stimulus. These results show that the features of the target stimulus can be decisive for the appearance of the facilitatory effect of a peripheral spatially noninformative prime stimulus.

“…Some authors (e.g., Cheal & Lyon, 1992) even identified poststimulus masking as a critical condition for precuing advantages based on comparisons of experiments with and without poststimulus masking or with different forms of poststimulus masking. However, because of the large accuracy differences between different masking conditions, such comparisons are hard to interpret On the surface, the poststimulus masking procedure is very similar to the external noise plus attention paradigm (Lu & Dosher, 1998; see below for a description) used in the current studies.…”

The external noise paradigm (Z.-L. Lu & B. A. Dosher, 1998) was applied to investigate mechanisms of spatial attention in location precuing. Observers were precued or simultaneously cued to identify 1 of 4 pseudocharacters embedded in various amounts of external noise. The cues were either central or peripheral. Both central and peripheral precuing significantly reduced threshold in the presence of high external noise (16% and 17.5%). Only peripheral precuing significantly reduced threshold in the presence of low, or no, external noise (11%). A perceptual template model identified different mechanisms of attention for central and peripheral precuing, external noise exclusion for central precuing, and a combination of external noise exclusion and stimulus enhancement (or equivalently, internal additive noise reduction) for peripheral cuing.In a high workload environment, a human operator might need to monitor a large number of information sources simultaneously. Whereas this might be accomplished by saccades, the eye movement system is limited by the relatively long time (about 200 ms) each saccade takes (Hallett, 1986). On the other hand, the existence of a faster spatial attention system was proposed about a century ago (Helmholtz, 186671911;Wundt, 1902), selecting regions of the visual field for further processing without eye movements. This view has been established by the more recent literature

“…The finding that discriminating by line arrangement is impaired by the addition of back- ground stimuli more than discriminating by orientation is (e.g., Beck & Ambler, 1973) might be interpreted as indicating that the perception of line arrangement specially requires focal attention (cf. Cheal & Lyon, 1992, 1994Cheal, Lyon, & Hubbard, 1991). Since orientation is believed to be a simple feature, whereas line arrangement involves a relationship between features, this has been regarded as evidence for the dependence of the perception of conjunctions (see, e.g., Treisman & Gelade, 1980;Treisman & Sato, 1990) or of the perception of spatial relationships (see, e.g., Julesz, 1981Julesz, , 1984Julesz, , 1986 on focal attention.…”
