Working memory may operate on unconscious perceptual contents, though it remains linked to conscious perception. A large, multisite replication (19 labs, 531 participants, 720 trials) of Soto et al. (2011) found above-chance accuracy (.55) on a visual discrimination task when participants reported not seeing the subliminal Gabor grating. Performance correlated positively with cue detection sensitivity (r = .228), and the regression intercept was significantly above chance (β₀ = .521). The study provides an open-access dataset and confirms that measures were reliable and valid, supporting the existence of unconscious working memory.
A survey of 249 participants, mostly in academia and about 40% experts in consciousness research, assessed views on the field's progress, funding, job opportunities, and scientific rigor. 78% of respondents said scientific research on consciousness has been making progress. However, most perceived obtaining funding and getting a job in consciousness research as more difficult than in other neuroscience subfields. Work in consciousness research was seen as less rigorous than other neuroscience subfields, but this perception was not linked to the perceived difficulty in funding and jobs. Global workspace theory was rated most promising overall (about 28%), while among non-experts integrated information theory (IIT) was most popular (about 22%).
