| description | Helmholtz asked whether one could discriminate which eye is the origin of one's perception merely based on the retinal signals. Studies to date showed that participants' ability to tell the eye‐of‐origin most likely depends on contextual cues. Nevertheless, it has been shown that exogenous attention can enhance performance for monocularly presented stimuli. We questioned whether adults can be trained to discriminate the eye‐of‐origin of their perceptions and if this ability depends on the strength of the monocular channels. We used attentional feed‐forward training to improve the subject's eye‐of‐origin discrimination performance with voluntary attention. During training, participants received a binocular cue to inform them of the eye‐of‐origin of an upcoming target. Using continuous flash suppression, we also measured the signal strength of the monocular targets to see any possible modulations related to the cues. We collected confidence ratings from the participants about their eye‐of‐origin judgements to study in further detail whether metacognition has access to this information. Our results show that, even though voluntary attention did not alter the strength of the monocular channels, eye‐of‐origin discrimination performance improved following the training. A similar pattern was observed for confidence. The results from the feedforward attentional training and the increase in subjective confidence point towards a high‐level decisional mechanism being responsible for the eye‐of‐origin judgements. We propose that this high‐level process is informed by subtle sensory cues such as the differences in luminance or contrast in the two monocular channels. |
