Women's own-gender bias in face recognition memory

Area of Science:

• Cognitive Psychology
• Social Psychology
• Neuroscience

Background:

• Women exhibit a memory advantage for female faces over male faces, a phenomenon known as the own-gender bias.
• The underlying reasons for this bias, particularly whether it results from differential attention during encoding, remain debated.
• Men generally do not show a comparable own-gender bias in face recognition memory.

Purpose of the Study:

• To investigate whether women's own-gender bias in face recognition memory is attributable to more effortful processing of female faces.
• To examine the role of attention during the encoding of faces in modulating this bias.
• To compare face recognition memory between genders under varying attentional demands.

Main Methods:

• Three experiments were conducted involving both male and female participants.
• Participants encoded images of male and female faces under either full attention or divided attention conditions.
• Recognition memory for the previously encoded faces was subsequently tested.

Main Results:

• Women consistently demonstrated a significant own-gender bias, remembering female faces better than male faces.
• Men did not show a reliable own-gender bias in face recognition.
• Crucially, the own-gender bias in women was not diminished under divided attention conditions, contrary to predictions based on effortful processing.

Conclusions:

• The findings suggest that women's own-gender bias in face recognition memory is not driven by increased effortful processing during encoding.
• The results support the hypothesis that women possess greater perceptual expertise for recognizing female faces, which enhances memory performance.
• This research contributes to understanding gender-related differences in face perception and memory mechanisms.
