3.3. Effect of the Amount of Visual Information

Likewise, we calculated a score reflecting the influence of varying the amounts of visual information on participants’ performance across all experiments. This score was obtained by subtracting the rate of correct responses obtained in conditions of high amounts to that obtained in conditions of low amounts of visual information, for both preferred and non-preferred intentions. Thus, the greater this score, the more participants’ performance was sensitive to increasing the amounts of visual information.

We then input this score in a 2x2x4 repeated-measures ANOVA with Bias (preferred vs. non-preferred intentions) as a within-subjects factor, and group (comparison vs. schizophrenic patients) and Type of Intention (motor vs. superordinate vs. social motor vs. social superord.) as between-subjects factors.
