Aim Precisionn.How close a player's response lands to the true target location, isolated from how quickly the response was made.Measured by · AimArousaln.A continuum of physiological and psychological activation from deep sleep to peak alertness, with an optimal midpoint for cognitive performance.Measured by · CombineAttention Spann.The duration for which an individual can direct focused attention toward a single task before attention drifts or performance degrades.Measured by · MemoryC3 entries
Choice Reaction Timen.The latency to select and execute one of several possible responses to one of several possible stimuli.Measured by · ReactionCognitive Loadn.The total working-memory demand a task places on a person at a given moment, relative to the resources they have available.Measured by · CombineComposuren.The capacity to maintain accurate, stable performance when task-irrelevant distraction or pressure is present, rather than a personality trait of general calmness.Measured by · ComposureD2 entries
Decision Qualityn.How accurately and appropriately a person selects among available response options, independent of how fast that selection is made.Measured by · Decision SpeedDivided Attentionn.The ability to allocate attentional resources concurrently across two or more tasks without a proportionate cost to either.Measured by · CombineE1 entry
Executive Functionn.An umbrella term for higher-order processes that govern goal-directed behaviour: inhibition, updating, and cognitive flexibility.Measured by · MemoryF3 entries
Flanker Taskn.An attentional paradigm in which a central target is flanked by compatible or incompatible distractor stimuli, measuring how much flanking noise degrades response accuracy and speed.Measured by · ComposureFlicker Detectionn.The ability to detect a brief, low-salience visual change or onset, often measured near the threshold where a flickering stimulus is just barely perceptible.Measured by · FlickFlow Staten.A state of complete absorption and optimal performance where skill and challenge are precisely matched and conscious self-monitoring recedes.Measured by · CombineG1 entry
Go/No-Gon.A response-inhibition paradigm requiring a quick response to go stimuli and full withholding to no-go stimuli.Measured by · ReactionI1 entry
Inhibitory Controln.The capacity to suppress prepotent, automatic, or competing responses in favour of a goal-directed action.Measured by · FlickM2 entries
Mental Fatiguen.A state of reduced cognitive resource availability produced by sustained demanding activity, distinct from physical tiredness or sleepiness.Measured by · CombineMicrosaccaden.A small, involuntary jerk-like eye movement that occurs during attempted visual fixation, preventing perceptual fading.Measured by · AimP2 entries
Posner Cueingn.A spatial attention paradigm that measures how preparatory cues speed or slow responses at cued versus uncued locations.Measured by · CombineProcessing Speedn.The overall rate at which the nervous system takes in information, transforms it, and generates a response, independent of any single task used to measure it.Measured by · CombineR2 entries
Reaction Timen.The interval between stimulus onset and motor response, combining detection, decision, and execution stages.Measured by · ReactionRisk Assessmentn.The evaluation of potential gains and losses under uncertainty, and the systematic, predictable biases that shape how people weigh them.Measured by · CombineS6 entries
Saccaden.A fast, ballistic eye movement that redirects gaze from one fixation point to another, following lawful and predictable timing rules.Measured by · AimSimple Reaction Timen.The time to execute a single pre-planned response to a single expected stimulus, with no choice involved.Measured by · ReactionSmooth Pursuitn.A continuous eye movement that keeps a moving target stabilized on the fovea, distinct from the rapid jumps of a saccade.Measured by · TrackingSpatial Resolutionn.The finest level of visual detail the eye and visual cortex can distinguish, most commonly measured through acuity and contrast sensitivity.Measured by · CombineStroop Effectn.The slowdown and errors caused when a word's meaning interferes with naming its ink colour.Measured by · ComposureSustained Attentionn.The capacity to maintain attentional focus and detection sensitivity over an extended monitoring period, measured by how much performance declines over time.Measured by · CombineT4 entries
Target Acquisitionn.The process of detecting a target and moving a cursor, crosshair, or gaze to it, modeled as a speed-accuracy tradeoff that scales with distance and target size.Measured by · AimTemporal Resolutionn.The finest interval of time over which the visual system can distinguish separate events rather than perceiving them as a single, fused event.Measured by · CombineTiltn.A state of impaired self-regulation triggered by a frustrating or costly outcome, producing measurably worse decisions immediately afterward.Measured by · TiltTracking Accuracyn.How closely a person's cursor or gaze follows a continuously moving target over time, distinct from the discrete accuracy of a single targeting response.Measured by · TrackingV1 entry
Vigilancen.The state of readiness to detect and respond to infrequent, unpredictable signals over a prolonged monitoring period.Measured by · CombineW1 entry
Working Memoryn.A limited-capacity system that holds and manipulates information in service of ongoing tasks.Measured by · MemoryNEURORANK · GLOSSARY · INDEX32 TERMS · 14 LETTERS WITH ENTRIESURL: neurorank.app/glossary
