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 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.

The Bivalent Shape Task Version 1.0 (Esposito et al., 2014). A simple nonverbal dimensional filtering task akin to the stroop task.

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.

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 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.

Numerical Stroop task where participants count items (1-3) while suppressing prepotent digit reading. Tests interference between counting and number naming.

The PEBL Switcher task: A novel task to measure cognitive flexibility and rule switching.

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.

Classic Stroop color-word interference test using the Victoria format with three conditions: color naming, word reading, and color-word interference.
