From: A database of heterogeneous faces for studying naturalistic expressions
Not all happy and fearful faces are created equal. (A) Radial plots showing the response rates for each emotion category for WFD faces that were most frequently categorized as expressing “happiness” (245 images; left) and “fear” (38 images; right). Note that even amongst these top ‘happy’ and ‘fearful’ faces, participants picked other responses to categorize the same expression. (B) Pie charts showing the proportion of the 245 happy (left) and 38 fearful faces (right) that were categorized using each of the other emotion categories. For example, while all of the 245 happy faces were categorized by at least one participant as signalling happiness (by definition), 13% of the happy faces were categorized by at least one participant as signalling disgust, and 36% of the happy faces were categorized by at least one participant as signalling surprise. Similarly, while all of the 38 fearful faces were categorized by at least one participant as signalling fear, 18% were categorized as happy and more than half (i.e., 71%) were categorized as signalling a recognizable but unspecified emotion (i.e., “other”).
