An inhibitory control task requiring participants to suppress the reflexive tendency to look at a peripheral cue. A cue appears on one side of the screen, followed by an arrow target on the opposite side. Participants must indicate the arrow's direction while avoiding looking at the initial cue, which would impair target perception. Involves a screen calibration routine so users can calibrate eccentricity based on paper, ruler, or credit card.
The PEBL Attentional Network Test (PANT) measures the efficiency of three attention networks: alerting, orienting, and executive control. Participants identify the direction of a central arrow while ignoring flanking arrows, with various cuing conditions to assess different attention components.
A measure of risk-taking behavior where participants inflate virtual balloons to earn points, balancing reward against the risk of the balloon popping.
PEBL's "Bechara Gambling Task": an independent implementation of Bechara et al.'s so-called "Iowa Gambling Task". Choose which option and receive rewards and costs. This version, by Peter Bull, is a substantial improvement over the original PEBL test, which is still available as iowa-old.pbl if needed.
A test of executive function and cognitive flexibility where participants sort cards according to changing rules.
A shorter version of the Berg Card Sorting Test using a 64-card deck instead of the standard 128-card deck, providing a quicker assessment of executive function and cognitive flexibility.
A brief test measuring statistical numeracy and risk literacy through probability questions
50-item IPIP representation of the Goldberg (1992) markers for the Big-Five factor structure, measuring Extraversion, Agreeableness, Conscientiousness, Emotional Stability, and Intellect/Imagination.
The Bivalent Shape Task Version 1.0 (Esposito et al., 2014). A simple nonverbal dimensional filtering task akin to the stroop task.
A simple choice reaction time task where participants type the letter displayed on screen as quickly as possible. Measures basic processing speed and response selection.
Color-word Stroop task focusing on ink color naming while suppressing the prepotent word-reading response. Supports keyboard or audio response modes.
A variant of the Trail Making Test requiring participants to connect circles in sequence using numbers (1-2-3-4), letters (A-B-C-D), or alternating patterns (1-A-2-B or A-1-B-2). Tests cognitive flexibility, task switching, and visual search speed.
PEBL Corsi blocks test is a visual-spatial working memory test. Subjects are asked to replicate sequences of clicks onto a set of spatially-arrayed square targets.
A test of verbal working memory where participants recall sequences of digits in forward and backward order.
An implementation of the Eriksen Flanker Task, a test of selective attention and response inhibition where participants identify a central target while ignoring flanking distractors.
A keyboard tapping task measuring low-level motor ability and psychomotor speed. Modeled after the Finger Tapping or Oscillation task from the Reitan Test Battery. Participants tap a key as quickly as possible for multiple trials, testing dominant and/or non-dominant hand.
A four-choice serial reaction time task from the UTC test battery (Wilkinson & Houghton, 1975). A plus sign appears in one of four screen quadrants, and participants press the corresponding key as quickly as possible. Optional auditory feedback for lapses.
A continuous performance task measuring sustained attention and response inhibition. Participants respond to frequent target stimuli (Go trials) while withholding responses to rare non-target stimuli (No-Go trials).
PEBL Clock Test. An implementation of the Mackworth Clock Test. A sustained visual attention task--Watch for a clock to skip a beat.
A spatial reasoning and planning task requiring participants to solve mazes by finding the shortest path from start to finish. Uses Kruskal algorithm-generated mazes with guaranteed solutions.
A multidimensional assessment tool for measuring subjective workload across six dimensions
Numerical Stroop task where participants count items (1-3) while suppressing prepotent digit reading. Tests interference between counting and number naming.
The PEBL OddBall Task. A response conflict task where participants respond to red circles and squares appearing on the left or right side of the screen.
Context-dependent sustained attention task. Respond to 'X' only when it follows 'A'. Measures context processing and response inhibition.
Test of sustained attention. Respond to all letters except 'X' by pressing spacebar. Measures attention lapses and false alarms.
Test of sustained vigilance and reaction time. Respond as quickly as possible when a stimulus appears. Widely used in sleep research.
Motor tracking task requiring continuous tracking of a moving target with mouse or touch input. Measures motor coordination and learning.
A 24-item self-report questionnaire measuring transient stress states during task performance

A simple test script for chain testing that demonstrates upload initialization, parameters, and data file upload functionality.
A simple reaction time task where a single stimulus (an 'X' or mouse button prompt) appears at a specifiable delay from the previous response. Measures basic alertness and motor response speed across multiple blocks with breaks.
The PEBL Switcher task: A novel task to measure cognitive flexibility and rule switching.
A standardized 10-item questionnaire for assessing the perceived usability of systems, interfaces, and products
PEBL Test of Attentional Vigilance (TOAV), a version of the TOVA.
A time estimation task from the UTC test battery (Jerison et al., 1957). A square target descends at constant speed, becomes occluded behind a wall, and participants estimate when it would reach a notch at the bottom. Tests temporal perception and mental extrapolation.
Two sleepiness scales: Karolinska Sleepiness Scale (KSS) and Epworth-inspired Tiredness Scale
Classic puzzle measuring planning and problem-solving. Move disks between pegs following rules: only one disk at a time, never place larger disk on smaller disk.
A test of executive function, specifically planning and problem-solving. Participants move colored disks between pegs to match a target configuration.
A test of visual search, attention, mental flexibility, and motor function where participants connect numbered or lettered circles in sequence as quickly as possible.
An 'urns' or 'marbles' task examining decision-making under uncertainty and impulsivity. Participants sample colored marbles from a hidden urn and must decide which of two urns (with different color distributions) is being used. More evidence-gathering improves accuracy but costs points.
Classic Stroop color-word interference test using the Victoria format with three conditions: color naming, word reading, and color-word interference.
A collection of six Visual Analog Scales (VAS) for measuring comfort, temperature sensation, Mental Exertion (RSME) and physical exertion (Borg's RPE)
A probabilistic category learning task based on Knowlton et al. (1994). Participants see 1-3 cards with different symbols, each probabilistically predicting sun or rain. Through trial-and-error with feedback, participants learn which cards predict which weather outcome. Tests implicit learning and habit formation.
