0:00 Title
0:09 What are the advantages and challenges in collaborations between neuroscientists and philosophers when studying free will?
18:11 Following this collaboration, how can an abstract notion like free will be probed experimentally?
32:08 If volition / free action must be reasons-responsive (i.e. NOT the Libet task) then how should we think about Libet-type actions? Are they just a degenerate case of decision-making where value is nil or is there something distinct about them?
36:40 "What are the expected neural/physical differences between:
1) a ""free-will zombie"" who does not have free will (could not have chosen option B in a 2AFC decision task, but thinks they could have) but retains the psychological feeling of having free will, and
2) a being who does have free will but not the psychological feeling of having free will (could have chosen option A or B in a 2AFC but does not realise it)?"
41:49 What do you think is the strongest argument or evidence for and against free will?
48:21 How would you characterize the relationship (if any) between consciousness and free will?
55:38 Do you think it is possible to provide a simple and unambiguous "mathematical" definition of the terms: awareness, consciousness, and attention?
1:02:42 Some decisions are considered to be biased to a certain degree or under certain conditions, without this endangering free will as a whole. Where would you draw the line after which the decision is unfree, or without moral responsibility?

Abstract: The stream of consciousness refers to ideas, images, and memories that meander across the mind when we are otherwise unoccupied. The standard view is that these thoughts are associationistic in character and they arise from subpersonal processes—we are for the most part passive observers of them. Drawing on a series of laboratory studies we have conducted as well as Buddhist models of mind, I argue that these views are importantly incorrect. On the alternative view I put forward, these thoughts arise from minimal decision processes, which lie in a grey zone: They are both manifestations of agency as well as obstacles to it.
Abstract:
The neural mechanisms underlying decision-making are typically examined by statistical analysis of large numbers of trials from sequentially recorded single neurons. Averaging across sequential recordings, however, obscures important aspects of decision-making such as variations in confidence and 'changes of mind' (CoM) that occur at variable times on different trials. I will show that the covert decision variables (DV) can be tracked dynamically on single behavioral trials via simultaneous recording of large neural populations in prefrontal cortex. Vacillations of the neural DV, in turn, identify candidate CoM in monkeys, which closely match the known properties of human CoM. Thus simultaneous population recordings can provide insight into transient, internal cognitive states that are otherwise undetectable.
