Self-related shapes can hold the eyes

Area of Science:

• Cognitive psychology
• Neuroscience
• Human attention research

Background:

• Individuals exhibit heightened sensitivity to self-related stimuli.
• The self-reference effect influences various cognitive processes, including memory and attention.

Purpose of the Study:

• To investigate if arbitrary stimuli associated with the self or a stranger can influence attention holding.
• To examine the role of task relevance in self-related attention biases using an oculomotor task.

Main Methods:

• Two experiments employed a manual matching task to link shapes (triangle/square) with the self and a stranger.
• Participants performed a saccade task with central shapes presented, varying trial-by-trial or block-wise based on task relevance.

Main Results:

• Participants were slower to initiate saccades away from self-associated shapes compared to stranger-associated shapes.
• This self-related attention bias was observed specifically when the self/other distinction was task-relevant (Experiment 2).

Conclusions:

• Arbitrarily learned self-associated stimuli can capture and hold attention.
• The self-reference effect on attention is modulated by the task's requirement to differentiate self from other.
