Figure 1.
In a RSVP trial, an observer identified a flashed number while being exposed to background scenes.
Target numbers and distractor letters at the screen center were equally bright or dim within a block. Their luminance was alternated across blocks. SOA = Stimulus Onset Asynchrony.
Figure 2.
In a training trial, an observer identified central letter while being exposed to weak motion signals.
Bright and dim letters were presented in alternating blocks and paired with different motion directions, respectively.
Figure 3.
In a testing trial, an observer judged whether moving dots constituted any coherent motion.
The motion coherence and direction were randomly varied from trial to trial.
Figure 4.
The number identification and scene recognition accuracy (y-axis) are averaged from all participants, and plotted against two conditions of task difficulty (x-axis). Error bars indicate standard errors of group means.
Figure 5.
The letter identification accuracy (y-axis) is averaged from all participants, and plotted against training day (x-axis). Error bars indicate standard errors of group means.
Figure 6.
The change of motion detection sensitivity (y-axis) is calculated by subtracting post- from pre-training sensitivity to each motion direction (x-axis), and averaged over all participants. Error bars indicate standard errors of group means.
