Introducing CCAB

CCAB streamlines in-home and in-lab cognitive assessment with high-precision automated testing and scoring

Test Anywhere

The CCAB has been normed for at-home and in-laboratory test administration.
CCAB tests are self-administered with examiner proctoring to assure test validity.
Potential error conditions are digitally flagged for rapid examiner correction.
Examiners can test multiple patients concurrently.
CCAB tests can be administered over cellular as well as Wi-Fi networks to assure universal test access.

Precise Verbal Tests

Unlike other computerized batteries, the CCAB includes a complete selection of verbal tests (e.g., logical memory, picture description, verbal fluency, etc.).
Stimulus intensities are adjusted to compensate for hearing loss.
Digital recordings are accurately transcribed and timestamped by consensus automatic speech recognition.
The analysis of recordings and transcripts quantifies temporal, lexical, phonological, syntactic, and semantic speech features.

Objective, Sensitive Analysis

Calibrated stimulus and response timing with timing uncertainty measures to assure valid test administration.
Objective scoring algorithms reduce bias and errors of manual scoring and enable more comprehensive quantification.
Comprehensive scoring models account for twice the performance variance as traditional (Age, Education, Gender) models further improving CCAB test sensitivity.
Reports include traditional accuracy measures, processing speed measures, and cognitive domain metrics.
NBS supports open data access to anonymized and deidentified CCAB normative data at www.osf.org/link.

Remote Testing

CCAB may be securely administered from patients’ homes or in any research or medical setting.
Screening tests, performance checks, and realtime monitoring ensure test validity.
Examiners may video chat with patients, initiate test sequences, and monitor test progress all through our web-based platform.

Automated administration

CCAB is designed for automated administration under examiner supervision.
A single examiner may test multiple patients concurrently.
Examiners are alerted in the event of a warning condition and may intervene at any time.
CCAB test scores are shown in real time during test administration.

Objective Analysis

Hardware-calibrated response and touch timing.
Verbal responses transcribed by consensus automatic speech recognition.
Advanced scoring algorithms reduce bias, error, and subjectivity of manual scoring.
Results report includes core measures of cognition, in addition to reaction time, processing speed, and language metrics.
