Table 1.

Mean proportion (%) of hits and confusions in human observers’ responses, and reaction times (for hits only) for each target (stimulus) expression.

Hits	98.5^a	93.7^a	91.7^a	80.7^b	77.8^b	68.6^c

Within each expression stimulus category (horizontally), scores with different letters across expression response (i.e., on the same line) are significantly different in post hoc multiple contrasts (p < 0.05, Bonferroni corrected); expressions sharing a letter are equivalent. Boldface for hits in columns.
