Moral judgement by the disconnected left and right cerebral hemispheres: a Split-Brain investigation.
Royal Society Open Science, 2017Co-Authors: Conor M. Steckler, J. Kiley Hamlin, Danielle R. King, Michael B Miller, Alan KingstoneAbstract:Owing to the hemispheric isolation resulting from a severed corpus callosum, research on Split-Brain Patients can help elucidate the brain regions necessary and sufficient for moral judgement. Notably, typically developing adults heavily weight the intentions underlying others' moral actions, placing greater importance on valenced intentions versus outcomes when assigning praise and blame. Prioritization of intent in moral judgements may depend on neural activity in the right hemisphere's temporoparietal junction, an area implicated in reasoning about mental states. To date, Split-Brain research has found that the right hemisphere is necessary for intent-based moral judgement. When testing the left hemisphere using linguistically based moral vignettes, Split-Brain Patients evaluate actions based on outcomes, not intentions. Because the right hemisphere has limited language ability relative to the left, and morality paradigms to date have involved significant linguistic demands, it is currently unknown whether the right hemisphere alone generates intent-based judgements. Here we use nonlinguistic morality plays with Split-Brain Patient J.W. to examine the moral judgements of the disconnected right hemisphere, demonstrating a clear focus on intent. This finding indicates that the right hemisphere is not only necessary but also sufficient for intent-based moral judgement, advancing research into the neural systems supporting the moral sense.

right hemisphere dominance for understanding the intentions of others evidence from a split brain Patient
Case Reports, 2009Co-Authors: Stephanie Ortigue, Danielle R. King, Michael B Miller, Michael S. Gazzaniga, Scott T GraftonAbstract:Understanding the actions performed by other people is a key aspect of social interaction, including in clinical settings where Patients are learning from therapists and caregivers. While lesions of the left cerebral hemisphere induce praxic disorders, the hemispheric specialisation of intention understanding remains unclear. Do Patients with a right hemispheric lesion understand the intentions of other people properly? The present study investigates how a Split-Brain Patient understands the means (what) and intentions (why) of the actions of other people. Results show a significant left hemispheric dominance for understanding what is done, and a significant right hemispheric dominance for understanding why an action is carried out. This discovery might have important clinical implications in neurological Patients, especially when those with right hemisphere lesions are faced with important decisions related to the interpretation of other’s intentions.

Split-Brain: What We Know Now and Why This is Important for Understanding Consciousness
Neuropsychology Review, 2020Co-Authors: Edward H.f. De Haan, Elizabeth Schechter, Anil Seth, Lukas Volz, Carlo Alberto Marzi, Mara Fabri, Paul M Corballis, Victor A. F. Lamme, Steven A. Hillyard, Tim BayneAbstract:Recently, the discussion regarding the consequences of cutting the corpus callosum (“Split-Brain”) has regained momentum (Corballis, Corballis, Berlucchi, & Marzi, Brain , 141 (6), e46, 2018 ; Pinto et al., Brain, 140 (5), 1231–1237, 2017a ; Pinto, Lamme, & de Haan, Brain, 140 (11), e68, 2017 ; Volz & Gazzaniga, Brain , 140 (7), 2051–2060, 2017 ; Volz, Hillyard, Miller, & Gazzaniga, Brain , 141 (3), e15, 2018 ). This collective review paper aims to summarize the empirical common ground, to delineate the different interpretations, and to identify the remaining questions. In short, callosotomy leads to a broad breakdown of functional integration ranging from perception to attention. However, the breakdown is not absolute as several processes, such as action control, seem to remain unified. Disagreement exists about the responsible mechanisms for this remaining unity. The main issue concerns the first-person perspective of a Split-Brain Patient. Does a Split-Brain harbor a split consciousness or is consciousness unified? The current consensus is that the body of evidence is insufficient to answer this question, and different suggestions are made with respect to how future studies might address this paucity. In addition, it is suggested that the answers might not be a simple yes or no but that intermediate conceptualizations need to be considered.
