Summary
This commentary by Gaspelin and Luck addresses a fundamental terminological confusion in the field of visual attention research, specifically regarding the definitions of "top-down" and "bottom-up" control mechanisms. The paper responds to arguments made by Theeuwes (2018), who proposed that top-down control is less prevalent than traditionally assumed and suggested that "selection history" (implicit mechanisms like priming or reward history) constitutes a distinct third mechanism. Gaspelin and Luck argue that Theeuwes’s critique relies on a flawed conflation of the term "top-down" with "voluntary" or "intentional." They contend that this semantic error obscures the actual mechanisms of attentional control and hinders scientific consensus. The authors’ approach is theoretical and definitional, relying on a review of established literature, textbook definitions, and classic experimental examples rather than new empirical data. They analyze how "top-down" processing has been historically defined in cognitive psychology and perception research. They contrast Theeuwes’s definition—which equates top-down control with slow, effortful, and voluntary processes—against the broader, standard definition where top-down processing refers to any perceptual phenomenon influenced by context, learning, expectation, or past experience. To illustrate their point, they cite introductory psychology textbooks and seminal works by researchers such as Baluch and Itti (2011) and Hopfinger et al. (2000), which distinguish between volitional top-down processes and top-down processes more generally. The authors demonstrate that "top-down" does not imply "voluntary" by presenting classic examples of involuntary top-down processing. They highlight the word superiority effect, where readers effortlessly perceive "CAT" and "THE" despite ambiguous letter shapes, and the auditory phonemic restoration effect, where masked sounds are restored in familiar words. These phenomena are driven by context and past experience (top-down) but are automatic and unconscious, not voluntary. They further note that selection history, which Theeuwes argues is distinct, fits squarely within the traditional definition of top-down control because it is driven by internal factors like past experiences. The authors acknowledge that some attention capture theories, such as the contingent involuntary orienting hypothesis, involve voluntary attentional sets that lead to involuntary capture, but argue this distinction is about the source of control, not a redefinition of the term "top-down." The significance of this commentary lies in its call for standardized terminology to facilitate progress in attention research. Gaspelin and Luck conclude that redefining "top-down" to mean only "voluntary" is inconsistent with the broader field and creates unnecessary confusion. They agree that selection history is an important area of study but insist it should be categorized as a form of top-down control. They suggest that future research should move away from long-block trial paradigms toward trial-by-trial cuing paradigms to better disentangle conscious strategies from selection history. By clarifying that top-down encompasses both voluntary and involuntary influences derived from internal states, the authors aim to resolve semantic debates and allow the field to focus on the actual mechanisms of attentional guidance.
Key finding
Top-down attentional control is not equivalent to voluntary control, as it encompasses involuntary processes driven by context, learning, and expectation.
