  1. Processing speed and consciousness Based around Jordan (2013)

  2. Who nose? • Try this: • Person 1: • Sit in a chair, eyes closed • Person 2: • Sit in another chair in front of you, facing the same way • Person 3: • Stand on right side of person 1. Take person 1’s right hand, and guide their index finger to person 2’s nose. • Use person 1’s hand to stroke and tap (mix it up) person 2’s nose in a random, unpredictable manner. • At the same time stroke and tap person 1’s nose using the EXACT same rhythm and stroke/tap combination. • Keep going for about a minute. • Get anything?

  3. Who nose? • What’s (where’s) the point? • Body image can be twisted within a few seconds. • Perception is about making things “work*”, no matter how weird or uncanny they seem. • *i.e. making connections between things • In this case, the only way to make sense of the simultaneous outstretched arm and nose contact is to grow a long nose (in perception anyway). • The ridiculousness of this, and yet it’s perceived reality, should convince you not to trust your senses too much • They are fooled in many other ways too, every time you move…

  4. The illusion of conscious will? • Conscious thoughts cause actions, right? • Not according to Wegner (2002)

  5. The illusion of conscious will? • Wegner (2002): • Illusion of conscious control comes from: • Thoughts precede actions (priority) • Actions consistent with the preceding thoughts (consistency) • Thoughts are only available cause (exclusivity)

  6. The illusion of conscious will? • Wegner (2002): • Illusion of conscious control comes from: • Thoughts precede actions (priority) • But…Libet (1985) • Bereitschaftspotential…1s before movement • Conscious intention only 200ms before movement

  7. The illusion of conscious will? • Wegner (2002): • Illusion of conscious control comes from: • Actions consistent with the preceding thoughts (consistency) • But… • Feelings of control emerge in chance events, even though they are patently chance events • Simple previous success leads to inaccurate feelings of control

  8. The illusion of conscious will? • Wegner (2002): • Illusion of conscious control comes from: • Thoughts are only available cause (exclusivity) • But… • RT task • You do the task, someone else sits behind you with their hand resting over yours • Participants in this scenario attributed 37% of errors to other person, despite the other person not touching them • Sense of agency is an illusion.

  9. The illusion of conscious will? • Jordan (2013) • Perhaps the problem is how we see consciousness • Thoughts are not to cause actions • The relationship is rather more complex than that… • James (1890) • What is pre-specified is the outcome, not the movement • Resident: immediate proprioceptive and other sensory consequences • Remote: seeing, hearing • Very remote: role of movement within other plans (e.g. making breakfast)

  10. Multi-Scale Effect Control • Jordan (2013) • All three sensible effects are • Pre-specified • Pre-specify effects that will result from movement • Jordan’s: this pre-specification of effects proceeds at “multiple time scales simultaneously”. • MSEC:
