The impact of appearance-based information on judgments about the psyc
hological functioning of pain patients was investigated. Video-tapes o
f low back pain patients experiencing pain were used as stimulus mater
ials. Subjects viewed silent video clips and photographs of the patien
ts' faces and made judgments about the functioning of these patients.
These judgments were affected both by patient physical attractiveness
and gender. Physically attractive patients and male patients were judg
ed to be functioning better than physically unattractive and female pa
tients. The judgments were reasonably described as biased because the
perceived differences about patients varying in attractiveness and sex
were not associated with measures of actual patient functioning.
