Processing speed and consciousness Based around Jordan (2013)

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 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? 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

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 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 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:
