Odds for fusion and fission illusions, Experiment 2 (spatial presentation).

The odds of fusion and fission illusions for multisensory stimuli and their uni-sensory equivalents in combined data from experiments 1 and 2. The LL and RR spatial configurations were collapsed and pooled with the data from experiment one. The rows labelled “All fission” and “All fusion” show data summed across all fission- and fusion-capable stimuli, respectively. The final odds ratio, and the significance of the association between stimulus type (uni- vs. multi-sensory) and reports of illusions (fissions/fusions vs non-illusory) are also shown.
