Spatial Perception
The core of our brain test mental assessment, measuring how you understand shapes, spatial structure, and visual rotation in real time.
Go beyond static quizzes.
IQbe is a premium IQ test and brain assessment that measures your cognitive health, 3D thinking, and executive problem-solving — in one fast, scientifically validated platform.
Most online IQ tests only check if you can spot a static pattern. IQbe goes further. It's a dynamic brain assessment that measures how you manipulate information, plan your response, and solve visual problems under real time pressure.
Beyond the laboratory validation study, IQbe has been completed by over 37,505 users from our internal dataset over the last two years. The score distribution below reflects this real-world usage, not normative population data.
Source: CogniFit IQbe internal user dataset. Score range 40–160 reflects the IQbe scaling; clinical batteries typically range 55–145. Scientific validation was performed separately (N=59 lab study).
Most users score between 85 and 115. The upper tail above 130 is larger than in a theoretical normal distribution, consistent with self-selected online samples.
IQbe is more than a standard IQ test. It is a comprehensive cognitive health and mental fitness evaluation that demands active manipulation, measuring processes that matter in real life.
The core of our brain test mental assessment, measuring how you understand shapes, spatial structure, and visual rotation in real time.
A critical part of your IQ intelligence: the ability to temporarily hold, manipulate, and actively use visual information.
Beyond typical intelligence tests, IQbe measures executive functions and the mental flexibility required to solve novel problems efficiently.
Identify patterns and logical relationships to evaluate your overarching fluid intelligence and cognitive potential.
IQbe is a digital, non-verbal IQ test designed to estimate fluid intelligence through interactive 3D problem solving. Inspired by Raven's Progressive Matrices, it measures how you analyze, manipulate, and solve visual problems efficiently.
Measures your ability to reason, detect patterns, and solve novel problems — independent of prior knowledge.
No language knowledge needed. Pure visual reasoning ensures fair assessment across all backgrounds.
Suitable for broad international audiences and varied educational backgrounds worldwide.
Rotate a 3D cube to locate missing pieces and infer the correct solution through spatial reasoning.
Works seamlessly online across desktop, tablet, and smartphone with adaptive interfaces.
Adds visuospatial and executive demands that make the cognitive task more dynamic and revealing.
IQbe measures not just whether you can see a pattern, but whether you can mentally manage and solve it.— IQbe Research

IQ scores are interpreted relative to a reference population. IQbe uses a familiar scale where 100 represents the middle of the distribution.
| Score Range | Interpretation | Distribution |
|---|---|---|
| Below 85 | Below average range ~16% of reference population | |
| 85–100 | Average range, lower half ~34% of reference population | |
| 100–115 | Average range, upper half ~34% of reference population | |
| 115–130 | Above average range ~14% of reference population | |
| 130+ | High range ~2% of reference population |
A score is not a complete portrait of a person's abilities, but it can offer a useful snapshot of reasoning and problem-solving performance.
IQbe was internally validated against Raven's Standard Progressive Matrices in a controlled lab study at Universidad Iberoamericana (Santo Domingo, Dominican Republic). In a sample of 59 university students, IQbe scores showed a moderate-to-strong positive correlation with Raven-based IQ scores.
The concurrent validity of IQbe was assessed in a controlled laboratory study at Universidad Iberoamericana (Santo Domingo, Dominican Republic). A sample of 59 university students (40 females, 19 males, aged 18–25) completed both the IQbe and a digitized version of Raven's Standard Progressive Matrices.
Findings: Pearson r = 0.613, p < .001 (95% CI approx. 0.42–0.76). This is considered a moderate-to-strong positive correlation in Cohen's classification, confirming that IQbe measures the same core constructs of fluid intelligence and reasoning ability as the established standard.
Limitation: Validation was conducted on a young adult university sample (ages 18–25). Generalization to other age groups and populations requires further study.
Reliability indicates whether a test produces stable and internally consistent results. IQbe showed adequate test-retest stability and internal consistency.
Test-retest reliability was assessed in a smaller subsample (N = 23, ages 18–54, retest interval ≥ 4 days) to measure how consistent scores remain over time.
The correlation of 0.71 demonstrates that IQbe yields stable estimates of a person's abilities across different testing sessions. These coefficients reflect the size of the validation sample. Larger studies are needed to refine these estimates.
Internal consistency indicates how well the different items within the test measure the same general construct. Evaluated via Cronbach's alpha (α = 0.78) on the validation sample (N = 59), IQbe demonstrates adequate internal coherence.
This means all items, despite increasing difficulty, consistently contribute to the measurement of fluid intelligence. These coefficients reflect the size of the validation sample. Larger studies are needed to refine these estimates.
Real-world cognition is not only about spotting a rule on a flat page. It also involves holding information in mind, manipulating it, planning the next step, and responding efficiently. IQbe was designed to bring those demands closer to the testing experience through interactive 3D problem solving.
