Effects of attention during encoding on sex differences in object location memory

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human Behavior

Background:

• Attention is crucial for memory, but its role in sex differences in object location memory remains unclear.
• Previous research highlights attention's general importance in memory tasks.

Purpose of the Study:

• To investigate the influence of attention (full vs. divided) on sex differences in object location memory.
• To examine how encoding conditions (incidental vs. intentional) interact with attention and sex on memory performance.

Main Methods:

• Two experiments with 186 participants using paper-based object arrays.
• Participants were assigned to either full or divided attention conditions during encoding.
• Incidental and intentional encoding tasks were employed across the two experiments.

Main Results:

• In incidental encoding, women outperformed men in object location memory under both full and divided attention.
• In intentional encoding, women's advantage over men was observed only under full attention, disappearing under divided attention.
• Sex differences in object location memory are modulated by attention and encoding type.

Conclusions:

• Attention significantly impacts sex differences in object location memory.
• The female advantage in detecting object location changes is context-dependent, particularly influenced by attentional demands during encoding.
• Findings clarify the conditions under which women exhibit superior object location memory compared to men.
