Cognitive Domain Definitions
Cognitive Domain Definitions
A clinical reference guide to the three cognitive domains Neurofit targets — what they are, how they're sub-divided, and which conditions commonly affect them.
Why this matters for providers
Neurofit organizes all activities around three cognitive domains: Memory, Attention, and Processing Speed. Understanding the clinical definitions behind these terms helps you communicate goals clearly in documentation, select the right activities for each client, and interpret progress data in a clinically meaningful way.
Memory
Clinical definition
Memory refers to the cognitive system responsible for encoding, storing, and retrieving information. In rehabilitation contexts, the focus is typically on the forms of memory most disrupted by neurological injury or developmental differences.
Sub-domains Neurofit targets
| Sub-domain | Description |
|---|---|
| Working memory | The ability to hold and actively manipulate information over a brief period. Acts as the brain's "mental whiteboard" — essential for following instructions, completing multi-step tasks, and academic or occupational functioning. |
| Sequential memory | The ability to encode and recall information in a specific order. Critical for procedural tasks, routines, and following directions. |
| Visual-spatial memory | The ability to remember the position, layout, or path of objects in space. Underpins navigation, spatial reasoning, and object tracking. |
What Neurofit addresses
Nature Path primarily targets working memory and sequential recall — clients must memorize a color and pattern sequence, then reproduce it in reverse. This places consistent demand on the working memory system, building capacity through progressive difficulty.
Conditions commonly involving memory deficits
- Acquired brain injury (ABI) and stroke
- Traumatic brain injury (TBI)
- ADHD (working memory component)
- Autism spectrum disorder (executive functioning overlap)
- Learning disabilities (especially dyslexia and dyscalculia)
- Early-stage neurodegenerative conditions
- Post-COVID cognitive effects
Attention
Clinical definition
Attention is a multi-component process that governs the ability to selectively engage with stimuli, sustain focus over time, and regulate cognitive resources. It is not a single skill — it encompasses several distinct sub-processes, each with distinct neural substrates.
Sub-domains Neurofit targets
| Sub-domain | Description |
|---|---|
| Sustained attention | The ability to maintain focus on a task over an extended period without significant lapses. |
| Selective attention | The ability to focus on a relevant stimulus while filtering out competing or irrelevant distractions. |
| Inhibitory control | The ability to suppress automatic or impulsive responses in favor of a deliberate, goal-directed action. Often called "impulse control" in clinical settings. |
| Attentional shifting | The ability to flexibly redirect attention from one stimulus or rule to another. Part of cognitive flexibility. |
What Neurofit addresses
Trail Making targets sustained and selective attention most directly — clients must visually scan a field, sequence targets in the correct order, and resist the impulse to click out of turn. Slowing down and reading the task carefully consistently improves scores, which builds metacognitive awareness of attentional habits.
Conditions commonly involving attention deficits
- ADHD (attention-deficit/hyperactivity disorder)
- ABI, TBI, and stroke
- Autism spectrum disorder
- Anxiety and mood disorders (attentional interference)
- Developmental coordination disorder
- Sensory processing disorders with visual attention components
- Post-COVID cognitive effects ("brain fog")
Processing Speed
Clinical definition
Processing speed refers to the rate at which the brain takes in, interprets, and responds to information. It reflects the efficiency of the neural networks underlying cognition — not just how fast a person moves, but how quickly and accurately they can make decisions.
Sub-domains Neurofit targets
| Sub-domain | Description |
|---|---|
| Visual processing speed | The rate at which the brain identifies and interprets visual stimuli. Affects scanning, pattern recognition, and reading. |
| Psychomotor speed | The combined speed of cognitive processing and motor execution — how quickly thought translates into a physical response. |
| Decision speed | The time required to evaluate options and commit to a response. Affected by both cognitive load and confidence. |
What Neurofit addresses
Both Trail Making and Nature Path are timed, meaning processing speed is a direct performance variable. Faster, more accurate responses on repeated sessions indicate genuine speed improvements — not accommodation. The platform tracks reaction time at the task level, giving providers a longitudinal view of processing efficiency gains.
Conditions commonly involving processing speed deficits
- ABI, stroke, and TBI
- ADHD (especially inattentive presentation)
- Multiple sclerosis and other demyelinating conditions
- Autism spectrum disorder
- Neurodegenerative conditions (Parkinson's, early-stage dementia)
- Aging-related cognitive change
- Post-COVID cognitive effects
Quick-reference: Conditions by primary domain
| Condition | Memory | Attention | Processing Speed |
|---|---|---|---|
| ADHD | Moderate | Primary | Moderate |
| Autism spectrum disorder | Moderate | Moderate | Moderate |
| Stroke / ABI | High | High | High |
| TBI | High | High | High |
| Learning disabilities | Moderate | Moderate | — |
| Post-COVID ("brain fog") | Moderate | High | High |
| MS / demyelinating | Moderate | Moderate | High |
| Developmental delays | Moderate | Moderate | — |
Note: Neurofit activities target all three domains across different exercises. Most clients benefit from a mixed assignment approach rather than isolating a single domain.
