Mitroff, Scholl and Wynn 2005, figure 2

Compare Scholl and Mitroff’s bouncing/streaming study. This study: (i) suggests solidity may be a constraint, at least sometimes; (ii) indicates that phenomenology and object indexes may not perfectly align
Mitroff et al p. 74: ‘we induced a strong bias to consciously perceive streaming, by using smooth, constant, and reasonably fast motion. This allows us to provide the clearest possible situation in which to evaluate the relationship between conscious percepts and object files.’ expectations can come apart in some situations.

Descartes: The will is the sole source of error.

Steve: What about sensory perceptions?

Descartes: Sensory perceptions do not represent.*

Steve: That’s untrue because sensory perceptions can conflict with judgements.

also representational momentum ...

You can do RM with the spiral setup too ...

Freyd & Jones, 1994 figure 2

predicted memory shifts: the representational momentum effect you would get if your subjects’ representational momentum were predicting the straight path.

Yet ‘our subjects had relatively accurate conscious knowledge of the trajectory of a ball exiting a spiral tube (63% to 83% chose the correct path; only 4% chose the spiral path).’

\citep[p.~975]{freyd:1994_representational}
it really is perception!

‘subjects showed a memory shift for a path that the majority of subjects did not consciously consider correct’
