Sustained Attentional Span represents the dual capacity to hold a specific amount of information in working memory while simultaneously maintaining focus on that information over an extended duration. It is the integration of attentional capacity (span) with temporal persistence (sustained attention), reflecting a highly efficient and resilient executive function. A high sustained attentional span is a hallmark of peak cognitive endurance and intellectual performance.
Origin
This is a composite term synthesizing two distinct concepts from cognitive science: “Attentional Span” (the quantity of information held) and “Sustained Attention” (the duration of focus). The term is used in clinical contexts to describe a superior, integrated cognitive state. It represents the maximal functional capacity of the brain’s working memory systems under prolonged stress.
Mechanism
The mechanism requires the harmonious, continuous function of the prefrontal-parietal network, which manages working memory and executive control. The system relies on the steady, modulated input of both dopamine and acetylcholine. Dopamine supports the stability of the neural representations in the working memory, while acetylcholine enhances the speed and clarity of signal transmission within the network. Hormonal support, particularly from thyroid hormones, ensures the high basal metabolic rate of these active neural regions is consistently met.
