Attentional bias towards emotional visual stimuli is a widely researched field; however, a theoretically important effect concerning attentional preference for emotional stimuli in the left visual hemifield (i.e., assuming a right hemispheric dominance in emotion processing) is still up for debate. A recent eye-tracking study from Gerdes et al. (2021) addressed, among others, the question whether there is an attentional leftwards bias for negative pictures. Specifically, negative and neutral pictures were presented in pairs in a free-viewing paradigm. The effect of picture position was tested on an attentional bias score, a difference value for initial fixations towards negative pictures compared to neutral ones. An enhanced attentional bias score was found for left picture position. However, we argue that the experimental design is missing a critical control condition to interpret this effect in relation to picture valence. Therefore, we conducted a conceptual replication and added a neutral-neutral picture pair condition with a corresponding bias score for arbitrary neutral A- versus B-pictures, to test if the leftwards bias also emerge in conditions where valence of the pictures is invariant. We replicated an overall attentional bias towards negative pictures and an increase of the attentional bias score for negative pictures presented on the left side. However, critically, higher attentional bias score was also demonstrated in the neutral-neutral condition when pictures from the arbitrary A-set were presented in the left visual hemifield. We argue that the experimental design and bias-score demonstrated here should be interpreted with caution regarding an interaction with picture valence.
