| Popis: | Binocular rivalry has been used to study a wide range of visual processes, from the integration of low-level features to the selection of signals that reach awareness. However, many of these studies do not distinguish between early and late phases of rivalry. There is clear evidence that the ‘onset’ stage of rivalry is characterized by stable, yet idiosyncratic biases that are independent of the subsequent alternations and perceptual biases experienced during sustained rivalry. Low-level stimulus features have robust effects in the onset phase that are not seen in sustained rivalry, suggesting these phases are driven by different neural mechanisms. The effects of high-level cognitive and affective factors at onset are less clear but also show differences from their effects in sustained viewing. These findings have important implications for the interpretation of any rivalry experiments using brief presentation paradigms and for understanding how the brain copes with binocular discrepancies in natural viewing conditions in which our eyes constantly move around an ever-changing environment. This review will summarize current research and explore the factors influencing this ‘onset’ stage. |
