Figure 4. Data and images for matching sounds to images with alternative audio-to-visual (AV) mappings.

Naive participants (N = 8) matched images and sounds with alternative AV mappings; the original mapping is the vOICe encoding. The error bars represent the standard deviation across participants, and the dashed line represents chance. The stars indicate that the modified mapping is significantly different from the original mapping.
