Attention, Bias & Performance

← Back to Domain-Specific Families

Abstractions about attention, cognitive bias, emotion, motivation, and task conditions that systematically shape memory, judgment, and performance.

17 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.
• Distraction — The involuntary capture of an agent's scarce attention by a salient secondary stimulus that wins a bottleneck competition against the primary task by its own salience rather than the agent's intent, imposing a performance cost plus recovery time.
• Dual-process Theory — Models cognition as the interaction of a fast, automatic, associative process (System 1) supplying default responses and a slow, effortful, rule-based process (System 2) selectively recruited to endorse or override them under conflict, novelty, or stakes.
• Emotional Response — The coordinated four-stage reaction an affective agent produces when a stimulus is appraised as significant for its goals: appraisal triggers a bundled physiological-expressive-motivational package that then biases subsequent attention, memory, and choice.
• Humphrey's Law — Consciously attending to a well-practiced automatic skill degrades it — declarative monitoring reinvested into a proceduralized pathway fragments and slows execution, which is why the expert chokes while the novice, who has no such pathway, does not.
• Initiative Loss — The failure mode in which an actor's decision cycle becomes structurally subordinated to an opponent's tempo, so every move is a forced reaction — a trap that faster reacting only deepens, recoverable only by changing the move-space.
• Near-Miss Effect — The operant finding that an outcome falling just short of the target — though it pays exactly zero — sustains responding more than a clearly distant failure, because the internal reinforcement signal is weighted by counterfactual proximity to the goal rather than by actual payoff.
• Negativity Bias — Weight a psychological impact function asymmetrically around zero so that negative stimuli, events, and information claim disproportionately more attention, memory, and motivational pull than equally intense positive ones, at a stable offset ratio commonly running several-to-one.
• Peak-end rule — Predict the remembered value of an extended experience from just two moments — its most intense point and its final moment, averaged — while the duration and the integral of momentary affect over the interior receive near-zero weight.
• 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.
• Social Bonding — Explain why affectively capable individuals keep routing help and protection toward one another long after any incentive would predict it: repeated shared experience and emotional co-regulation forge a durable bond that generates behaviour above and orthogonal to current incentives.
• Stimulus–Response Compatibility — When a stimulus automatically activates a response code, performance improves if that code agrees with the task-mandated response and degrades if the codes conflict, even when the triggering feature is irrelevant.
• Task-Switching Cost — Isolate the performance penalty paid at the moment of changing between rule-sets — separate from either task's steady-state difficulty — by contrasting switch trials against repeat trials in the same mixed block, and split it into a preparation-reducible part and an irreducible residual.
• Tetris Effect — The involuntary persistence of patterns from a recently, intensively practised activity into perception, imagery, and dreams — memory consolidation replaying strongly encoded content through a non-declarative pathway as a side-channel of skill learning.
• 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.
• Zeigarnik Effect — The finding that interrupted or unfinished tasks are recalled better than completed ones, because beginning a task installs a persisting goal-tension that keeps its representation activated until completion discharges it — scaled by goal-importance and gated on the interruption reading as a pause.
