Ocular fixation. (a) Normalized fixation durations across conditions in two representative participants, one younger (upper row) and one older (lower row) adult. The point of ocular fixation is given by the central red cross. (b) Average eye positions relative to the fixation cross in the groups of younger (n = 42, upper row) and older (n = 42, lower row) participants for the two viewing conditions (full-field in the left column and peripheral vision with an artificial scotoma on the right column). The red, green and blue discs respectively represent these positions for translational, radial and rotational optic flow patterns. The horizontal and vertical segments provide the 95% confidence intervals on the x and y axes. Although the stimulated portion of the visual fields covered 58.1° by 43.7°, we only represented here the near surround of the fixation cross (± 12°) to improve the visibility of the data.
