Findings reveal how category-specific attentional templates pre-activate in visual search, indicating the importance of strategy.

To investigate the pre-activation dynamics of category-specific attentional templates (CAT) in visual search tasks.
Defined targets as color-defined categories (warm, cool) based on prototype, semantic, and strategy frameworks.
Utilized the RSPP paradigm for consistent task difficulty while measuring pre-activation using N2pcs.
Conducted ERP and MVPA analyses to track activation patterns across different CAT types.
Semantic-based CAT pre-activated first at approximately 1200 ms before the search display.
Prototype-based CAT followed at 900 ms before the display, while strategy-based CAT was activated at around 600 ms.
Found significant differences in activation patterns for various category frameworks.
