Figure 1
The effect of stimulus type (male or female voice) and false information on ratings of voice pitch, with two-tiered CI for mean pitch ratings. The outer tier (thin lines) depicts a 95% CI for the individual mean. The inner tier (thick lines) is adjusted so that means with intervals that do not overlap are different with approximately 95% confidence.
