Integrating information from invisible signals: the case of implied motion

1s target Subjective measure5 Objective measure Visibility? Direction? 500ms 500ms iMAE ~ implied Motion After-Effect Motion direction can be extrapolated from static stimuli implying motion, and give rise to MAE1. This implies the existence of high-level visual processes, in which different features of the image are integrated into a unified percept. Is this integration process available in the absence of awareness? Recent results2 indicate that it may be the case, since incongruities between invisible objects and their background can still be detected despite unwareness. Here, using fine-grained MAE measures, we tested whether object-background segmentation and implied motion could be inferred from invisible images. 1. Unconscious: block design 4. Repetition priming
