What is the Origin of Attentional Vigor?

The term integrates concepts from cognitive neuroscience, specifically the study of attention and vigilance, with psychophysiology, which links mental states to underlying biological and hormonal parameters. "Vigor" implies a dynamic, energetic quality to attention, contrasting with passive or merely sustained focus, suggesting a state of peak cognitive performance.

What is the Mechanism of Attentional Vigor?

Attentional Vigor is primarily mediated by the prefrontal cortex and its dopaminergic and noradrenergic projections from brainstem nuclei. Dopamine plays a crucial role in maintaining task salience and motivation, while norepinephrine is essential for alertness and the filtering of distracting stimuli. Hormonal factors, particularly the precise diurnal rhythm of cortisol and the circulating levels of thyroid hormones, significantly influence the neurotransmitter balance necessary for this sustained cognitive state.

Attentional Vigor

Meaning

Attentional Vigor describes the qualitative and quantitative measure of an individual’s capacity for sustained, high-quality focus and mental energy, reflecting a robust neurobiological state. It encompasses both the intensity of concentration and the duration over which that focus can be maintained without significant cognitive fatigue or distraction. This concept is intimately linked to the optimal function of catecholamine and dopamine pathways, which modulate alertness and executive function.
