Processing speed and consciousness

Processing speed and consciousness

Based around Jordan (2013)


Who nose

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?


Who nose1

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…


The illusion of conscious will

The illusion of conscious will?

  • Conscious thoughts cause actions, right?

    • Not according to Wegner (2002)


The illusion of conscious will1

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)


The illusion of conscious will2

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


The illusion of conscious will3

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


The illusion of conscious will4

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.


The illusion of conscious will5

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)


Multi scale effect control

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”.
