In this paper, we examine whether information about an item's category, provided by the same dimension type presented across multiple spatial locations (which we term within-dimension features), is processed independently or pooled into a common representation. We use Systems Factorial Technology (SFT; Townsend & Nozawa, Journal of Mathematical Psychology, 39, 321-340, 1995) and fit parametric logical rule-based models to diagnose whether information processing is serial, parallel, or coactive. The present work focuses on expanding the scope of categorization response time (RT) models by synthesizing recent work in perceptual categorization with theories of visual attention. Our results show..
