Cognitive assessments for reasoning, memory and processing speed
Explore reasoning, recall and response timing through focused educational tasks. Results distinguish what you did from what the scoring model estimates. These tools are not standardized cognitive assessments.

Memory Test
The classic digit-span task, forward and backward — your working-memory span against internal illustrative references, in about five minutes.
Test your span → Available nowReaction Time Test
Simple visual reaction time — how fast you respond to a single cue. Five scored trials, median result, honest device-latency caveats, in about two minutes.
Test your speed → Available nowProcessing Speed Test
Cognitive throughput, not just reaction time — thirty timed same/different comparisons scored as correct judgments per minute, so both speed and errors count.
Compare fast → Available nowSpatial Reasoning Test
A mental-rotation task — same shape rotated, or a mirror image? Twelve items scored on accuracy and speed, with exact ground truth.
Rotate some shapes → Available nowVerbal Reasoning Test
Analogies, synonyms, and antonyms across three difficulty tiers — a difficulty-weighted measure of crystallized verbal ability, in about five minutes.
Reason with words → Available nowLogical Reasoning Test
Number series, syllogisms, deduction, and odd-one-out across three tiers — a culture-fair, difficulty-weighted measure of fluid reasoning, in about five minutes.
Follow the logic → Available nowNumerical Reasoning Test
Number series, word problems, ratios and data across three difficulty groups, with observed accuracy and an internal difficulty-weighted index.
Test your numbers → Available nowCreativity Test
The Alternate Uses Task — two minutes to list as many uses for an object as you can. Honest divergent-thinking fluency, with no automated originality rating.

Five reasoning domains, one profile
The reasoning exercise reports several task domains alongside its composite estimate. Differences between those tasks can add context, but they do not define a complete cognitive profile.
-
Pattern
Fluid reasoning
Spotting the rule behind a sequence and predicting what comes next — the closest thing to raw fluid intelligence, and the least dependent on anything you were taught. Test your logical reasoning → · The science →
-
Numeric
Quantitative reasoning
Relationships between quantities: proportions, progressions, and structure in numbers. This is reasoning with numbers, not arithmetic recall — a calculator won't help.
-
Verbal
Language & inference
Analogies, meaning, and what follows from what. Verbal reasoning leans on crystallized knowledge more than the other domains, which is exactly why it's measured separately. Test your verbal reasoning →
-
Spatial
Mental rotation & form
Holding a shape in mind and transforming it — folding, rotating, recombining. Strong spatial profiles cluster in engineering, design, and the trades. Test your rotation → · The science →
-
Memory
Working-memory span
Temporary maintenance and manipulation during a short span task. Performance can change with distraction, sleep, stress, strategy and previous exposure. Test your span → · The science →
After the test
Reading your result honestly
A score without context is flattery. These are the two pages that turn your number into understanding.
Conditions matter. Record distractions, fatigue and the device you used. Treat the results as a session snapshot; they do not establish a fixed ability or an empirical confidence interval.

Questions
About this category
What does the Cognition category cover?
Educational tasks for reasoning, memory, reaction time, rotation and creativity. Results show task measurements or clearly labeled internal indices. None establishes a population rank.
Why does the IQ test measure five separate domains?
Because the reasoning exercise samples several different task types. Looking at the pattern across tasks can add context, but AurorIQ does not treat that pattern as a complete model of intelligence or personality.
Is a high score in one domain and a low score in another normal?
Different task results can vary within the same session. Treat those differences as observations from this set of tasks, not as fixed labels or population-ranked strengths and weaknesses.
