A cognitive function is a mental ability that we use to understand, decide, remember, communicate, or solve a task.

They are not rigid labels. They are ways to describe processes that often work together.
Main Functions
Among the most common are attention, memory, language, perception, processing speed, and executive functions.
Executive functions help to organize, inhibit impulses, change strategies, plan, and review errors.
Key idea: training should adapt to the person's actual state, not the other way around.
Tasks Mix Processes
An exercise rarely trains just one thing. Reading requires attention, working memory, language, and speed. Copying a pattern may require visual perception, memory, and motor control.
That’s why it’s useful to describe each challenge by its main function and the secondary functions that also participate.
What Can Be Observed
Not only successes matter. Errors, times, omissions, impulsivity, need for help, fatigue, and stability can also be observed.
Functional neuropsychology looks at performance within a context: how the person was, what task they did, and what pattern appears over time.
How to Connect It with Reactiva+
In Reactiva+, each game can be associated with cognitive domains. This helps to choose challenges, create programs, and explain to the user what they are practicing.
The goal is not to turn the app into a diagnosis but into a clear tool to guide training and monitoring.
- Attention: Selecting and maintaining focus.
- Memory: Recording, maintaining, and retrieving information.
- Language: Understanding, expressing, and organizing words.
- Executive: Planning, inhibiting, and changing strategy.
What You Can Train in Reactiva+
A challenge for each function described in the article:
- Correct Color: selective attention, with interference involved.
- Position Memory: visuospatial memory.
- Rule Switching: executive functions: flexibility and rule changing.
- Verbal Relations: language and verbal reasoning.
- Quick Symbolization: processing speed.
- Functional Calculation: calculation applied to everyday situations.
A cognitive function is a mental ability we use to understand, decide, remember, speak, or solve something.

They are not fixed labels: they describe processes that often go together.
The main ones
Attention, memory, language, perception, processing speed, and executive functions (organizing, planning, changing strategy).
Tasks mix several at once
Almost no exercise trains just one thing. Reading needs attention, memory, and language at the same time. Copying a drawing needs good vision, remembering, and controlling movement.
What can be observed
It is not only important to get it right. Times, errors, need for help, and signs of fatigue also matter.
How it connects with Reactiva+
Each game can be linked to a function. This helps choose challenges and explain what is being trained at each moment.
What you can train in Reactiva+
- Correct Color: attention.
- Memory of Positions: memory.
- Verbal Relationships: language.
- Rule Switching: executive functions.
