Scale of timing
“gaussians” drawn by hand

Wearden, Wearden &
———————
feedback and no feedback conditions
– when you use feedback it will washout any effect


Penton-Voak et al 1996
told you need to produce 500ms and are pretty good

Veirordt (1868) experiments had two taps
Jayazeri & Shadlen 2010 used a computerized version of “ready set go”. – based on the mean

/////
Lejeune & Wearden 2009
$$$$

::::::
hardly anyone has looked at motor timing
Silvie? Droit-Volet (2010) European Journal of.. – read her papers – reproduction is contaminated by motor factors
..
@@@@@@
VERBAL ESTIMATION
@@@@@@

“give limits” between x1 and x2
