The effects of goal-driven attention on the acquisition of location probability learning.

Increasing evidence has shown that implicit learning shapes visuospatial attention, yet how such learning interacts with top-down, goal-driven attention remains unclear. This study investigated the relationship between task goals and selection history using a location probability learning (LPL) paradigm. We tested whether a top-down spatial cue facilitates or interferes with the acquisition of implicit LPL. In a visual search task, participants were asked to give precedence to one of four, spatially cued, quadrants of the screen. Unbeknownst to them, there was an underlying uneven spatial probability in which the target appeared disproportionately often in the cued quadrant (37.5%) and a second, uncued quadrant (37.5%). To assess what participants had learned, neutral, uncued testing trials with an equal target location probability (25%) were used. Results revealed faster search times in the cued and the uncued high-probability quadrants compared to the two low-probability quadrants and these fast search times remained prevalent in the neutral testing blocks. Importantly, LPL was comparable between the cued and uncued locations in the testing blocks, suggesting that the spatial cue neither facilitated nor interfered with LPL. These results support the dual-system view of attention, revealing parallel systems supporting both goal-driven and experience-guided attention.
