Domains of cognition and their assessment

Open access
Harvey, Philip D.·2019·Dialogues in Clinical Neuroscience

Abstract

Cognitive performance is typically conceptualized in terms of domains of functioning. These domains are hierarchical in nature, with the bottom referring to more basic sensory and perceptual processes and the top referring to elements of executive functioning and cognitive control. Domains are not independent of each other and executive functioning exerts control over the utilization of more basic processes. Assessments are typically targeted at subdomains of each ability area and careful combination of tasks can reveal patterns of performance consistent with a variety of different neurological and neuropsychiatric conditions. This review covers the general structures of domains, the patterns of impairments across domains seen in common neuropsychiatric conditions, and use of assessment strategies to differentiate, to the extent possible, between different types of conditions manifesting cognitive impairment. .

TL;DR

This review describes cognitive performance as organized into hierarchical domains, from basic sensation/perception to executive functioning and cognitive control, and reviews how assessments target subdomains to reveal patterns across neurological and neuropsychiatric conditions. It emphasizes that domains are intercorrelated, executive functioning supervises simpler processes, and processing speed is often the most impaired and functionally relevant domain in conditions such as schizophrenia.

Key findings

  • Cognitive domains are hierarchical and not independent: basic sensory/perceptual operations are least complex, while executive functioning/reasoning and problem solving are most complex and coordinate multiple lower-level abilities.
  • Assessment patterns can differentiate conditions: in cortical dementia and amnestic conditions, encoding, delayed recall, cued recall, and delayed recognition are all impaired; in frontostriatal conditions, encoding and delayed recall are impaired but delayed recognition and cued recall are typically spared. Similar patterns are reported in schizophrenia spectrum conditions.
  • Attention profiles differ by condition: psychotic populations commonly show increased CPT errors of omission and reduced d′ without increased errors of commission, whereas ADHD is associated with increased errors of commission and greater B; schizophrenia spectrum individuals fail to develop the normal bias to respond to nontargets when target frequency is high.
  • Processing speed is particularly important: coding-task performance is the most significant impairment in schizophrenia and the cognitive domain most strongly correlated with everyday functioning, and it tends to be the strongest predictor of overall cognitive performance. The paper also gives task examples such as digit span forward about 6 digits versus backward about 5 digits, HVLT with 12 items and 3 learning trials, CVLT with 16 items and 5 trials, and RAVLT with 15 unorganized items and 5 trials.

Methods

  • Narrative review of cognitive domains and their assessment, organized by general ability area and commenting on top-down versus bottom-up structure and regional brain functioning.
  • No primary data, systematic sample, or quantitative synthesis are reported; the paper synthesizes cited neuropsychological tests, clinical populations, and prior literature.
  • Main analysis is conceptual: it reviews performance-based assessments and then observational/self-reported functioning, with focus on humans.

Limitations

  • The paper states that fully addressing assessment of memory-disordered populations is beyond its scope, and it notes inconsistencies in the clinical/research literature about whether some processes belong in broader domains such as executive functioning or simpler domains such as processing speed.
  • The paper also states that some cognitive abilities may not be clearly separable into one domain or another.
  • Evident from the text: this is a narrative review without a systematic search, meta-analysis, or empirical sample, and the paper itself notes that larger factor-analytic studies often find a single global ability factor, raising questions about the separability of conventional cognitive domains.

    Following instructions such as ignoring distractors, dividing attention to process one of two concurrent information streams, or following other instructions in processing speed tasks are clearly executive or "cognitive control" demands.

  • Cognitive development can be classified into general processes such as memory, attention, executive function, and language development.

    “There are several ways to classify cognitive development, one of them being general processes involved, such as memory, attention, executive function and language development [8].”

    From Impact of social media on cognitive development of children and young adults: a systematic review (2025) · cites this paper as [8]

    The ‘Global structure of cognitive ability domains’ section lists memory, attention, language, and executive functioning as ways to classify cognitive abilities by general process. It does not present this as a classification of cognitive development or specifically discuss language development. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-10.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-10.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
