The present work recorded frequencies of five poses (left profile, hal
f-left profile, full-face view, half-right profile, and right profile)
by examining 4,180 single-subject portraits of various media. Statist
ically significant differences were found between the incidence of hal
f-left and half-right profiles. These differences found across media,
authorship, and five centuries of portrait work are consistent with ri
ght-hemisphere activation models in attentional bias and perception of
emotion.
