BACKGROUND AND OBJECTIVES: Excessive engagement in counterfactual thinking (CFT), where individuals imagine alternative outcomes to past events, is associated with rumination, a process characterized by repetitive negative self-referential thoughts. Attentional control difficulties are closely linked with rumination, and negative thoughts can negatively impact attentional control among rumination-prone individuals. This study aimed to investigate the relationship between CFT and emotional and non-emotional attentional control among individuals with varying levels of self-critical rumination. METHODS: A sample of 100 female participants, characterized by varying levels of self-critical rumination, completed a choice task resulting in goal failure, during which they reported their levels of CFT. Subsequently, participants performed an attentional control task involving eye-tracking measures to assess emotional attentional engagement, emotional attentional disengagement, and emotional and non-emotional attentional shifting. RESULTS: Among women with high (but not low) self-critical rumination tendencies, increased levels of CFT were associated with slower attentional shifting from emotional stimuli of opposing valence, as well as between non-emotional stimuli. LIMITATIONS: The correlational design of the study prevents causal interpretations of the findings. Additionally, the exclusive inclusion of female participants may limit the generalizability of the results. CONCLUSIONS: This study underscores the association of CFT with subsequent attentional control among women prone to self-critical rumination, aligning with prior research suggesting a link between negative thoughts and attentional processes. Future research should explore these relationships in diverse populations and consider longitudinal designs to elucidate causal pathways.
