Cognitive research asks how we deal with conflict, and what cognitive adjustments occur during information processing. According to the conflict monitoring theory (Botvinick et al., 2001), registration of conflict signals the need for increased cognitive control. Traditionally, this phenomenon has been studied using simple conflict tasks, such as the Stroop task. More recently, however it has been proposed that conflict processing may operate as a domain-general mechanism. Specifically, some authors argued that conflict arising in the language domain can influence subsequent conflict processing in unrelated domains (e.g., Simi et al., 2023). We here examined whether verbal and pictorial conflicts elicit response slowing, a well-documented effect in the sensorimotor domain, and whether conflict processing in pictures resembles that observed in language. In two studies, participants evaluated sentences and pictures that were either congruent or incongruent with world knowledge (e.g., a panda drinking beer [incongruent]). While sentences elicited the expected conflict effect - longer RTs for incongruent compared to congruent stimuli - this effect did not emerge for pictures. This pattern suggests that conflict processing varies across stimulus modalities, pointing to a potential domain-specific rather than domain-general mechanism. Building on this, an ongoing study examines whether conflict in one modality can trigger cross-modal adjustments influencing processing in another - for instance, between pictorial and linguistic representations. To our knowledge, this is the first study to investigate how individuals detect conflicts between incoming information and world knowledge across different modalities, advancing our understanding of the cognitive architecture of conflict processing across domains.
