This study investigated gentler differences in the accuracy of self-pe
rceptions and whether self-perception biases are related to negative r
ecall biases. Participants were 275 female and 213 male college studen
ts. Approximately 10% of the participants were minorities (mostly Afri
can American and Asian). On a masculine task, gender differences in se
lf-perceptions were found for three measures of accuracy: The accuracy
of self-evaluations, calibration, and response bias. Females underest
imated their performance, were less well calibrated and showed a more
consevative response bias than did males. Ar; hypothesized, no gender
differences in the accuracy of self-evaluations were found for feminin
e and neutral tasks. Participants' expectancies mediated the gender di
fferences in post task self-evaluations of performance. In addition, e
vidence for a negative recall bias was found. Females were more likely
than males to recall their mistakes even with performance and accurac
y of self-evaluations controlled. The implications of females' greater
self-perception biases on masculine tasks are discussed and suggestio
ns for future research are made.
