Understanding Cognitive Domains

Working Memory

The ability to hold and manipulate information in mind over short periods.

Why it matters: Working memory supports daily tasks like following conversations, remembering instructions, and managing finances.
When it declines: Decline leads to forgetting recent events, difficulty multi-tasking, and trouble following complex instructions.
How we train it: Sequence games and n-back tasks directly exercise the neural circuits underlying working memory.

Attention

The capacity to focus on relevant information while filtering out distractions.

Why it matters: Attention underlies virtually all cognitive tasks — reading, driving, conversations, and learning new skills.
When it declines: Reduced attention leads to increased errors, accidents, and difficulty concentrating in noisy environments.
How we train it: Spotlight and Stroop games train selective and sustained attention under increasing cognitive load.

Processing Speed

How quickly the brain processes and responds to information.

Why it matters: Processing speed is the single strongest predictor of everyday competence in older adults.
When it declines: Slowed processing makes conversations harder to follow, reading less efficient, and reactions slower.
How we train it: Speed Sort directly trains the speed-of-processing pathway identified in the landmark ACTIVE trial.

Executive Function

Higher-order skills including planning, flexibility, inhibition, and decision-making.

Why it matters: Executive functions are essential for independent living, financial decisions, and managing health care.
When it declines: Executive decline leads to impulsivity, poor planning, difficulty adapting to change, and vulnerability to scams.
How we train it: Stroop Challenge and Pattern Architect engage inhibitory control and fluid reasoning respectively.

Language

Verbal fluency, word retrieval, comprehension, and the ability to express ideas clearly.

Why it matters: Language abilities support social connection, self-advocacy in medical settings, and mental health.
When it declines: Language decline manifests as tip-of-the-tongue moments, reduced vocabulary use, and communication difficulties.
How we train it: Word Weaver exercises verbal fluency and lexical access through active word retrieval under time pressure.

Visuospatial

The ability to understand and remember spatial relationships between objects.

Why it matters: Visuospatial skills support navigation, reading maps, recognizing faces, and understanding visual information.
When it declines: Early decline affects driving ability, getting lost in familiar places, and difficulty with visual tasks.
How we train it: Memory Palace directly exercises visuospatial memory, which is affected early in mild cognitive impairment.
