In recent empirical work, Pinto and colleagues found that two split-brain subjects were able to respond to stimuli, verbally or unimanually, equally well regardless of where those stimuli appeared in their visual fields. On the basis of this preserved capacity for crossed responses, Pinto and colleagues argue that a split-brain subject has a unified consciousness since, apparently, they remain unified qua agents. This talk concerns under what conditions crossed responses provide evidence for unified agency and thus perhaps for conscious unity as well.
