FIGURE 2.

Behavioral results. (A) Signed error, calculated as the mean difference between actual and indicated target position, in the body-fixed condition for all displacement sizes and directions, pooled across participants. Negative error indicates error to the right, error bars denote standard error. (B) Same as A in the world-fixed condition. (C) World- and body-fixed behavior as expressed by gain factors per condition, where the darker bars indicate world-fixed gain and lighter the body-fixed gain. World-fixed gain factors increase with smaller motion. Error bars denote standard error. (D) Remembered target positions for the world-fixed condition, collapsed over left and right motion, relative to fixation (0, dashed line) for each participant (filled circles). Initial targets are indicated by black open circles, actual target locations after motion are indicated in gray open circles. Mean remembered locations do not cross fixation in the small motion condition, but do cross in the medium and large displacement conditions, as indicated by the vertical black lines (mean perceived locations after motion, horizontal lines denote standard deviation).
