Looking to the future: automatic regulation of attention between current performance and future plans

Area of Science:

• Cognitive Neuroscience
• Neuroimaging

Background:

• Prospective memory involves remembering to perform actions in the future.
• Coordination of attention between ongoing tasks and future intentions is crucial but not fully understood.

Purpose of the Study:

• To investigate the neuro-cognitive mechanisms underlying attention allocation in prospective memory.
• To examine how attention is automatically coordinated between ongoing task performance and future action plans.

Main Methods:

• Developed a novel prospective memory task with manipulated temporal intervals of targets.
• Utilized functional magnetic resonance imaging (fMRI) to observe brain activity.
• Analyzed behavioral performance on both prospective and ongoing tasks.

Main Results:

• Behavioral performance showed a trade-off: faster/better prospective memory in expanding intervals at the cost of ongoing task performance, and vice versa.
• fMRI revealed distinct patterns of activation in anterior medial prefrontal cortex and anterior cingulate cortex correlating with these behavioral trade-offs.
• These effects occurred without participants' awareness of the temporal sequence.

Conclusions:

• Attention allocation in prospective memory is automatically regulated by medial frontal cortex regions.
• This automatic regulation coordinates attentional resources between current and future-oriented tasks.
• No strategic control or explicit instructions are needed for this automatic attention coordination.
