The conceptual framework that views human attention as a scarce, finite neurocognitive resource and its allocation as a system governed by economic principles. In a physiological context, this relates to the limited capacity of the prefrontal cortex for executive function and cognitive load, which directly impacts the hormonal stress response system. Chronic attention fragmentation, driven by pervasive stimuli, can lead to allostatic load and measurable dysregulation of endocrine homeostasis.
Origin
The term originated in the late 20th century within the domains of information science and business, recognizing the immense value of consumer attention in a media-saturated environment. Its clinical application emerges from modern neuroendocrinology, linking sustained cognitive demand to quantifiable physiological and hormonal dysregulation. This concept effectively bridges cognitive psychology with stress physiology, highlighting a significant modern environmental stressor.
Mechanism
Continuous cognitive switching, necessitated by external stimuli competing for finite attention, requires persistent, high-level resource allocation from the central nervous system. This sustained demand triggers the activation of the sympathetic nervous system and the subsequent release of stress hormones, specifically cortisol and norepinephrine. The mechanism involves the hypothalamic-pituitary-adrenal (HPA) axis responding to the perceived ‘threat’ of information overload, which, if chronic, results in glucocorticoid receptor downregulation and impaired metabolic function.
