This test measures the ability to concentrate on specific instructions under changing conditions. In Phase 1, you see a prompt asking for a certain shape (e.g., “Press the Circle”). In Phase 2, color is added (e.g., “Press the Red Circle”), sometimes with a misleading text color on-screen. Each round shows four options—one correct, three distractors—and you tap the correct one as quickly as possible. Scoring rewards fast, accurate responses. Mistakes or slow taps yield fewer (or no) points. By shifting between shape-only and shape-plus-color demands, this test highlights how effectively you filter irrelevant information and maintain focus.
The Balloon Analogue Risk Task (BART) is a well-known experimental measure originally designed to assess risk-taking behavior. CerebreX’s Balloon Test presents a modified version of the classical test.
In the Balloon Test, you will press a button to inflate a virtual balloon, trying to earn points with each pump—while risking that the balloon can pop at any moment. By balancing rewards (pumping the balloon for more points) against risk (popping leads to zero for that trial), the test evaluates how participants make decisions under uncertain risk conditions.
The Card Deck Test presented in is a decision-making game where you make choices under uncertainty to maximize your points. CerebreX’s Card Deck Test takes inspiration from well-known gambling and card-based cognitive tasks (such as the “Iowa Gambling Task”) used in psychology and behavioral economics research. The primary goal is to evaluate how you handle risk, probability estimation, and reward maximization.
The Clock Drawing Test is a classic way to assess visuospatial skills and executive functioning. It’s commonly used in clinical and research settings to gauge a person’s ability to understand, plan, and execute a simple drawing task. CerebreX’s Clock Drawing Test is our own modified version of this well-known assessment, adapted for an engaging digital experience. We’ve incorporated features such as draggable hands, snapping angles, and automatic scoring thresholds to provide rapid feedback on performance.
In this test, you’ll see a blank clock face and be given a target time (e.g., “6:15”). Your job is to drag the hour and minute hands until they match the target time—within 30 seconds. Once you submit, our unique scoring system grades how close your placement is to the correct angles, awarding points based on accuracy. By testing both precision and speed, the Clock Drawing Test offers insights into core cognitive functions such as planning, attention, and visuospatial reasoning.
The Concept Shifting Test draws inspiration from the classic Trail Making Test, a widely recognized measure of executive functioning, cognitive flexibility, and visual attention. CerebreX has created its own modified version to keep the spirit of “connecting items in the right order” while offering a more dynamic and visually engaging format.
In CerebreX's modified version of the Concept Shifting Test, you’ll see circles labeled with letters and numbers around the edges of the screen. Your goal: tap them in the correct sequence (e.g., simple numeric order, or alternating between numbers and letters) under time pressure. Each correct tap brings you a step closer to completing the phase, while mistakes and delays affect your score. By gradually increasing complexity across phases (A, B, and C), this test highlights your mental flexibility—the ability to switch between tasks and keep the correct order in mind.
The classic Corsi Block Tapping Test measures visuospatial working memory—your ability to recall and reproduce sequences of spatial locations. CerebreX has developed a customized, digital version that retains the test’s foundational principle but incorporates new elements such as a sleek 3×3 grid, dynamic highlight animations, and a special scoring mechanic rewarding perfectly recalled sequences with bonus points.
In this test, you’ll watch a series of blocks flash in a specific order, then attempt to tap them in the exact same sequence. Each correct tap boosts your score; if you nail the entire round perfectly, you double your points for that round. By increasing sequence length across multiple rounds, the test adapts to different skill levels, revealing just how many positions you can hold in short-term spatial memory.
The Flanker Task is a longstanding measure of selective attention and cognitive control, often used to examine how well a person can focus on a target while ignoring distracting information. CerebreX presents its own adapted version of this test, adding varied arrow strings, custom color changes, and a specialized scoring formula to track both speed and accuracy under distractions.
In this test, you’ll see a line of arrows on-screen. Your goal is to quickly identify the direction of the middle arrow—left or right—even when it’s surrounded by arrows pointing in conflicting directions. Each round challenges you to respond accurately and quickly, awarding more points for faster, correct answers and fewer (or zero) for mistakes or slow reactions. Over multiple trials, the test captures both overall performance and average reaction time, offering insights into your ability to filter out distractions and maintain focused attention.
The Go/No-Go paradigm is a well-known measure of inhibitory control and impulse regulation, often used in cognitive psychology to evaluate how quickly and accurately individuals respond—or withhold a response—when presented with a cue. CerebreX offers its own version on this classic method, adding elements such as varying shapes, changing time limits, and a dynamic scoring system that rewards quick, correct presses (“Go”) and penalizes improper presses on “No-Go” targets.
In this test, certain shapes (e.g., Circle, Star) are your “Go” cues. Tap them as fast as possible to score points—bonus points if you react quickly. Other shapes (e.g., Square, Cross, Hexagon) are “No-Go,” meaning you should resist tapping altogether. Each correct decision influences your speed challenge: consecutive successes can shorten viewing time (increasing difficulty), while errors may adjust the test to be more forgiving.
Logical reasoning tasks are widely used to evaluate analytical thinking, pattern recognition, and problem-solving abilities.
In this CerebreX rendition, we’ve built upon traditional sequence and logic puzzles, but introduced unique scoring, an interactive UI, and speed bonuses for quick responses.
During this test, you will face a series of numeric sequences—often progressive or pattern-based. You choose the missing number from several possible answers. Each correct and speedy selection boosts your points, while errors reduce your overall score. By blending accuracy and response time, this test highlights not only your logical reasoning but also your mental agility.
Simple arithmetic tasks can reveal a great deal about processing speed and mental calculation skills. CerebreX’s Basic Math Test builds upon traditional math drills, but modernizes them with time-based scoring, random problem generation, and adaptive feedback. Instead of merely solving equations, you’ll race against a short timer to select the correct answer, earning more points for faster responses.
In this test, you’ll see a starting number and a subtractor (like 63 – 9), then choose from multiple options. Answer quickly to maximize your time bonus—but watch out, as incorrect or overly slow guesses reduce potential points. By introducing timers, dynamic transitions, and an instant feedback overlay, the test blends the simplicity of basic arithmetic with an energetic, game-like feel.
The Math Multiplication Test expands on basic multiplication drills, introducing a mix of straightforward (e.g., “7 × 8”) and more complex equations (e.g., “(3 + 2) × 4”). CerebreX combines simpler problems with parenthetical operations for a more comprehensive challenge that captures calculation speed, accuracy, and adaptability under pressure.
In this test, you’ll face a series of six questions—three from an “easier” set and three from a “harder” one, merged to ensure variety. Each question appears with multiple-choice answers, and you’ll earn more points for correctness and quick responses. If you take too long or pick the wrong answer, your score suffers. This simple yet dynamic scoring system keeps the pace lively and the experience engaging.
The Complex Math Test challenges participants with multi-step arithmetic problems involving parentheses, addition, subtraction, multiplication, and division—all arranged in a brief, fast-paced format. By combining simpler equations with more layered calculations, CerebreX gauges not only basic computational skill but also mental flexibility and error-checking under time pressure.
In this test, you’ll encounter five questions: three moderately difficult and two more advanced. Each query has four possible answers, and you must select the correct one before time runs out. Quick and accurate responses earn greater points through a time bonus, while mistakes or delays can cut into your final score. This approach ensures that you’re tested on both accuracy and speed, providing deeper insight into your cognitive efficiency.
CerebreX’s Memory Test tasks you with memorizing five words in a short time, then typing as many as you can recall. The words appear in a random order and vanish quickly. Our scoring system rewards each word remembered in the correct position yet still grants points for correct words out of place, ensuring a detailed measure of your recall. This design provides a straightforward yet nuanced way to capture both exact recall and partial recognition, giving you deeper insight into your short-term memory skills.
CerebreX’s Memory Recall Test measures how well you’ve retained words from the previous Memory Test. Once it starts, you enter the words you remember into text fields. We emphasize correct order—granting maximum points for exact positioning—but also award partial credit for words recalled out of place. A final screen shows how many were correct and in the right positions while letting you compare your answers to the original list. This setup highlights both precise and partial retrieval, offering a thorough view of your memory accuracy.
CerebreX’s Mental Rotation Test adapts the classic “rotated shapes” challenge by adding orbiting objects and scoring that encourages swift, accurate identification. You’ll see a reference shape at the top, with multiple moving shapes below. Tapping the correct match quickly yields higher points; errors or timing out deduct from your total. Up to three attempts carry you through progressively tougher rounds, tracking how promptly you recognize shapes from altered angles. Though mental rotation is long-established in cognitive research, CerebreX’s version introduces dynamic visuals and immediate feedback, creating a distinctive spin on this visual-spatial measure.
The Number Sequence Test challenges your short-term memory and working memory by showing you digits to remember and then type them. Each phase has a new sequence, a limited memorization time, and more digits as you progress, revealing how quickly and accurately you can recall them. After studying the digits, the display disappears, and you must type them exactly. Each correct digit in the right position earns points, with advanced phases awarding more points per digit. As you move through four phases, difficulty increases and time limits vary, shining a spotlight on how robust your working memory is under pressure.
The Odd One Out Test tasks you to quickly spot the single item that differs. The time-based scoring system rewards speedy identification, while errors or timeouts reduce points. Over multiple phases, item grids grow bigger and distractors appear, raising the challenge. Pulsing shapes create a dynamic environment but also demand attention to subtle differences in shape or color. After each round, a quick transition screen shows correctness and reaction time. Though “odd one out” tasks are longstanding, CerebreX’s modern approach integrates randomized placement, progressive difficulty, and lively feedback. This fosters an engaging test of visual discrimination.
The Pattern Completion Test measures visual reasoning by challenging you to find which image correctly completes a given pattern. CerebreX has added rotating puzzle pieces and partial-image cuts that raise the complexity each round. You’ll see a reference pattern at the top, plus multiple animated half-images below. Tap the correct match before time runs out; right answers earn higher points if you respond quickly, while mistakes or letting the clock hit zero cost you. Over five increasingly tricky rounds, more pieces and varied cuts appear, demanding fast scanning and precise recognition. This creates a lively, time-pressured puzzle-solving experience.
The Pattern Match Test challenges you to spot and tap every occurrence of a specific symbol in a grid before time runs out. CerebreX adds changing colors, shuffling symbols, and incremental phases to push your visual scanning and attention skills. In each round, you’ll see a reference symbol alongside a grid of mixed icons; each correct press increases your score, while errors cost points. If you find all required matches, you earn bonus points before advancing to tougher phases. Over time, random color changes and symbol shuffles complicate the grid, demanding quick detection. This fast-paced approach tests both accuracy and timing under dynamic conditions.
The Risk-Reward Test asks you to choose between a guaranteed payout and a higher-stakes gamble each round. CerebreX tracks how often you decide to take the risk, plus whether you win or lose on that gamble. In total, five rounds let you see how your decisions affect your final earnings. Taking the sure reward adds a consistent amount to your total; going for the gamble can bring bigger payoffs or leave you with nothing. By the end, the app calculates your average risk-reward ratio, translating it into a final score that highlights how daring or conservative your choices were.
The Spatial Navigation Test challenges you to remember and recreate a path drawn on a grid. CerebreX’s version shows a shape connecting dots, gives you a brief time to memorize it, then asks you to draw it from memory. Correct positioning of your strokes earns points, with a partial-credit system granting some reward if you’re close. Each round uses progressively more complex shapes, and your final score reflects both accuracy and order-based precision. Visual scanning and short-term memory come together here, testing how well you recall a path’s trajectory and replicate it under mild time pressure.
The Stop-Signal Test measures response inhibition by presenting colored circles that either require a press or indicate no press. Red and Yellow circles are “Go” signals: tap quickly to earn points unless a small white dot appears (the “Stop” signal). Green and Blue circles are “No-Go” signals: do not tap. Quick, correct presses boost your score, while mistakes or ignoring time-limits reduce it. Consecutive successes speed up the stimuli, increasing difficulty. By tracking both impulsive taps on forbidden signals and timely inhibition, CerebreX’s version captures your ability to suppress a learned response under pressure.
The Color-Word Challenge measures how quickly you can name the displayed text color rather than the word’s meaning—an exercise in inhibitory control and selective attention. CerebreX’s version shows words like “RED” in a different color, and you must tap the button that matches the text color, not the word. Each correct tap within 0.8 seconds earns the highest points, with gradually fewer points for slower responses. Mistakes yield no points. Across ten rounds, the difficulty fluctuates with random word-color pairs, challenging your ability to suppress the automatic tendency to read the word instead of focusing on its color.
CerebreX’s Tower of Hanoi Test challenges you to move a stack of disks from one peg to another under classic rules: move only one disk at a time, and never place a larger disk on a smaller one. After a short countdown, you have 60 seconds to solve. Fewer moves and faster solves yield a higher score, while inefficient moves or running out the clock lower your final results. By balancing planning and quick adaptation, this test highlights both your strategic thinking and ability to stay calm under time pressure.
CerebreX’s Tower of London Test presents a puzzle with colored balls placed on pegs of varying capacities. Your goal is to match a specified target arrangement of these balls in as few moves as possible, and before time expires. One peg can hold up to three balls, another two, and the smallest peg just one. You tap pegs to pick up and drop a ball, with each valid move demanding foresight to avoid placing bigger balls on smaller ones. Fewer moves and faster completion raise your score; inefficient or slow attempts reduce it. This setup tests executive planning and quick decision-making under constraints.
CerebreX’s Trail Making Test challenges attention and sequencing by asking you to tap a set of points in ascending order. Phase A involves numbered targets, while Phases B and C mix letters and numbers, increasing difficulty. Each correct tap continues the sequence; errors cost points and momentarily show an incorrect overlay. Time-limits per phase (30–40 seconds) add pressure to finish swiftly. After each phase, your partial score is based on speed and accuracy. By incorporating letters, numbers, and strict tapping rules, the test offers a concise yet revealing look at executive function—tracking how efficiently you switch between tasks under time constraints.
The Visual Memory Test challenges you to memorize a set of colored shapes in a short time, then arrange them in the exact same order you saw them. CerebreX’s version displays five unique shape-color combinations for you to note within 20 seconds. When time’s up, the shapes shuffle, and you must reorder them to match the original layout. Each correct match yields points, with fewer points the more mismatches there are. By blending color distinction, shape recognition, and short-term recall under time pressure, this test provides a succinct measure of visual memory and attentional focus.
