Attention, Arousal & Performance

Abstractions about how attention allocation and arousal level shape performance and affect — biased attentional selection, flow-state engagement, the inverted-U of arousal in the Yerkes-Dodson law, and expectation-driven shifts like the placebo and positivity effects.

5 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Attentional Bias — The systematic tilt in how finite attention is allocated across the perceptual field — pulled by anxiety, reward history, depression, or expertise rather than sensory salience — a property of the perceiver, at perceptual selection, upstream of judgment.
• Deep Engagement
• Placebo Effect — An inert intervention produces a real, measurable improvement because the patient's expectations recruit the body's own regulatory pathways — which is why efficacy must be judged by a controlled comparison, not a single-arm gain.
• Positivity Effect — The age-graded shift in attention and memory toward positive and away from negative information, driven not by chronological age but by a narrowing perceived time horizon that re-weights goals — a goal-driven, load-sensitive strategy, not a passive decline.
• Yerkes–Dodson Law — The finding that task performance improves with arousal up to an interior optimum then deteriorates — an inverted-U whose peak sits at lower arousal for complex tasks and higher for simple ones, so under- and over-arousal are opposite failures needing opposite fixes.
