Abstract:
People often claim seeing images completely despite performing poorly. This highlights an issue with conscious representations. We introduce an experimental manipulation aiming to disentangle two prevalent positions: Rich views posit that people virtually represent the external world with unlimited capacity; Sparse views state that representations are reconstructed from expectations and information. In two experiments using the object recognition task, we tested two probe types: Images, which should aid reconstruction more, and Words, which should aid it less. From a sparse view, one should expect that Images lead to greater accuracy and reported experience. We found no reliable differences in accuracy and reported experience across probe types; however, we observed that the object positions influenced both accuracy and reported experience, which is surprising from a Rich view as it seemingly requires assumptions of different access across the visual field. Both theoretical positions thus currently need further development to explain our results.
