What is the Origin of Sustained Attention Metrics?

This terminology comes from psychometrics and cognitive neuroscience, where 'sustained attention' is a core executive function domain. 'Metrics' refers to the standardized, quantifiable scores derived from continuous performance tests.

What is the Mechanism of Sustained Attention Metrics?

Maintaining this state requires continuous, low-level activation of attentional networks, primarily dependent on stable dopamine signaling in the prefrontal cortex. Hormonal balance ensures the necessary metabolic fuel is consistently delivered to support this prolonged neural firing pattern. Fluctuations in cortisol or thyroid hormone can directly impair the fidelity of the signal processing required for this endurance task.

Sustained Attention Metrics

Meaning

Quantitative measurements used to assess the ability to maintain a consistent focus on a specific, often monotonous, task over an extended duration, reflecting the stability of underlying cortical resources. These metrics are sensitive indicators of neuroendocrine fatigue, particularly concerning sustained catecholamine function and glucose supply to the frontal lobes. Poor performance often correlates with compromised HPA axis regulation or suboptimal energy throughput. We define the limits of unwavering mental concentration.
