Objective:
Facial image recognition is an
important part of forensic personal identification. In forensic applications, this method
is used for identifying faces of
suspects at the crime scene, to
detect the features through the
facial recognition, and to compare the facial images of suspects with a criminal database.
Apparent effects of gender differences on visual perceptions
and cognitions were often reported. The aims of this study
were to determine the accuracy
rates of identification through
auricle for which morphological
appearance of auricle shapes
with naked eyes by inexperienced volunteers is used and compare the accuracy rates of male
and female observers.
Methods:
This study was performed in three
stages: gathering 120 auricle
images (60 rights and 60 lefts) of
30 male and 30 female volunteers (between 18-26 years of age);
observations of 100 volunteers
(50 males and 50 females) inexperienced on identification, and
statistical analysis with SPSS-11
Statistics Software.
Results:
The rates of correct responses
were calculated by proportional calculation method as 84.9%
(SD:13.43) for all observers, 84.1%
(SD:11.68) for male observers and
85.7% (SD:15.05) for female observers. The difference of accuracy
rates between male observers and
female observers was not statistically significant (p>0.05).
Conclusion:
Although the differences of males
and females in cognitive tasks are
well-known, a difference between
the genders in the capability of
identification through the auricles
images could not be determined
in the present study. Forensic scientists from both sexes can serve
in identification through auricle
with same reliability.
