We’ve been building an online cognitive testing platform and recently expanded it with a separate training section focused on specific cognitive functions rather than only IQ scoring.
One interesting pattern we kept noticing was how uneven cognitive profiles can be across users.
Some people perform very well on pattern recognition but struggle with working memory updating. Others show strong recall accuracy with relatively slow processing speed. In timed tasks, there’s also a noticeable tradeoff between speed and precision depending on the individual.
The training section currently includes exercises around:
-
Working memory
-
Attention control
-
Processing speed
-
Pattern recognition
-
Mental flexibility
-
Spatial reasoning
-
RSVP-based reading speed
-
Verbal retrieval
From a modeling perspective, it has been interesting to think about how these task-level differences relate to broader latent constructs like fluid intelligence or executive control, especially when performance variance changes under time pressure.
One thing we’re considering is whether repeated interaction data from these kinds of exercises could eventually become more informative than isolated single-session testing.
Curious how people here think about:
-
task-specific performance vs general intelligence factors
-
speed/accuracy tradeoffs in cognitive tasks
-
whether cognitive training datasets can meaningfully model individual cognitive profiles over time
