Expectations accelerate entry of visual stimuli into awareness

Journal of Vision June 26, 2015 Yair Pinto, Simon van Gaal, Floris P. de Lange et al. 177 citations

Expectations speed up conscious perception. In four experiments using predictive cueing and continuous flash suppression, expected images entered awareness faster than neutral or unexpected ones. This effect was not due to response priming, stimulus associations, or attentional timing biases. Top-down expectations had a stronger influence when visual input was ambiguous, consistent with predictive processing accounts. The findings support the idea that conscious access depends on verifying perceptual predictions.

Split-Brain: What We Know Now and Why This is Important for Understanding Consciousness

Neuropsychology Review May 12, 2020 Edward H.F. de Haan, Paul M. Corballis, Steven A. Hillyard et al. 86 citations

Cutting the corpus callosum (split-brain) broadly disrupts functional integration across perception and attention, but some processes like action control remain unified. The key unresolved question is whether split-brain patients have split or unified consciousness. Current evidence is insufficient to decide, and future studies may need to consider intermediate conceptualizations beyond a simple yes or no.

Conscious visual memory with minimal attention.

Journal of Experimental Psychology General January 30, 2017 Yair Pinto, Annelinde R. E. Vandenbroucke, Marte Otten et al. 23 citations

Change blindness—the failure to notice unattended changes in a visual scene—has been taken as evidence that conscious perception requires spatial attention. However, change blindness tasks introduce visual interference that forces reliance on working memory, which has limited capacity. Before such interference, a larger-capacity store called fragile memory exists. Two experiments show that minimizing spatial attention nearly eliminates visual working memory but leaves fragile memory largely intact. Furthermore, minimally attended fragile memory responses produce accurate metacognition, indicating that conscious memory persists with limited spatial attention. These findings suggest that both visual consciousness and memory can be supported by only minimal attention.
