Monitoring Attention in Self and Others.

Area of Science:

• Neuroscience
• Cognitive Science
• Social Cognition

Background:

• Metacognition, the ability to monitor one's own cognitive states, is crucial for attention control.
• Understanding others' attention is vital for social interaction and predicting behavior.
• It remains unclear if distinct or overlapping neural networks support self-referential versus other-referential attention monitoring.

Purpose of the Study:

• To investigate whether the same cortical networks are involved in metacognitive representations of one's own attention compared to another person's attention.
• To identify the specific brain regions engaged during self-monitoring versus other-monitoring of attention.

Main Methods:

• Functional magnetic resonance imaging (fMRI) was used to scan participants' brain activity.
• Participants performed two tasks: monitoring their own attention (Self condition) and monitoring an actor's attention (Other condition).
• Brain activity was analyzed just before participants indicated a lapse in attention (their own or the actor's).

Main Results:

• Both Self and Other attention-monitoring tasks activated overlapping brain regions, including the temporoparietal junction (TPJ), precuneus, dorsomedial prefrontal cortex (dmPFC), anterior cingulate cortex (ACC), and anterior insula.
• These activated areas showed partial overlap with the default mode network, social cognition network, and salience network.
• While significant overlap existed, distinct patterns of activity also suggested differences between self- and other-focused attention monitoring.

Conclusions:

• A common set of cortical areas may underpin a general mechanism for attention metacognition.
• These findings suggest a shared neural architecture for monitoring one's own attention and inferring others' attentional states.
• Despite shared networks, specific neural processes likely differ between self- and other-referential attention monitoring.
