Are attention and consciousness inherently intertwined or distinct aspects of cognition? One report (Jiang et al. 2006) presented clear results in evidence of the latter. In this earlier study, the authors used a continuous flash suppression (CFS) paradigm which presents a colorful pattern to the dominant eye and stimuli of interest to the non-dominant eye; the colorful pattern masks the relevant stimulus from awareness. On each trial, the authors presented a sexually stimulating image and a scrambled image on different sides of a computer screen during CFS. They found that, even though participants were not consciously aware of the images, intact images that matched participants' sexual orientation could still capture attention.

 

Despite these seemingly clear results, the authors of the current Stage 1 manuscript pointed out that CFS studies are often not replicated, and the paper by Jiang et al. (2006) is no exception. Therefore, Chen et al. (2023) seek to replicate this study using a Bayesian (rather than NHST) analytic approach. This method will allow the authors to determine the strength of evidence for their hypotheses.

 

In this Stage 1 manuscript, Chen et al. present an introduction that motivates the replication, and a pilot study that replicated the procedure of Jiang et al. (2006) conducted with 21 participants. This led to a well-motivated statistical sampling plan and some small design changes for the main experiment, such as adding a staircasing procedure to remove potential performance ceiling effects, and using less extreme wording for stimulus attractiveness ratings. A clear study design template is presented, detailing the different hypotheses that will be tested, and what different outcomes would indicate.

 

The Stage 1 submission was evaluated by the recommender and two expert reviewers. Following revisions, the recommender judged that the manuscript met the Stage 1 criteria and awarded in-principle acceptance (IPA).

 

 

Level of bias control achieved: Level 6. No part of the data or evidence that will be used to answer the research question yet exists and no part will be generated until after IPA.
