Accurate Assessments, Administered Anywhere.

Our test battery is designed to provide reliable and robust cognitive performance data.

Diagnosis is difficult. 

 

Manually administered tests of memory and cognition have proved to be time-consuming and costly.

Additionally, there is a wealth of data that is never captured by traditional pen-and-paper tests.

Challenges to the Current Testing Model

Inter/Intra-Examiner Reliability

In manual scoring, different examiners may record the same finding in different ways. Alternatively, the same examiner may record similar findings differently over time. Similar problems may occur during administration. 

Lack of Remote Administration Options​

Manual testing requires travel and extended face-to-face contact between patients and examiners. These are deterrents to testing for many individuals.

Lost Phonetic Data

Manual scoring doesn’t allow for intensive analysis of phonetic anomalies that may prove to be pathologically significant.

Cost​

The time-intensive nature of comprehensive neuropsychological assessments—which take at least 12 hours to administer, score, and analyze—make regular neuropsychological testing cost-prohibitive.

Accessibility​

An aging population, coupled with rising rates of Alzheimer’s and Dementia, have left us critically unprepared to meet testing, diagnosis, and treatment needs. In the United States, this effect will be particularly damaging in rural and Spanish-speaking communities.

CCAB Features

Remote Test Administration

  • Our remote monitoring Examiner software allows for patients’ to complete the CCAB from home. This is an essential function for immunocompromised, homebound, and rurally located patients.
  • LTE-enabled tablets automatically run the CCAB Test-Station upon start-up.
  • Examiners may video chat with patients, initiate test sequences, and monitor test progress all though the CCAB Examiner interface.

Automated Testing and Scoring

  • The CCAB increases testing efficiency by allowing a single CCAB examiner to administer multiple tests concurrently.

  • CCAB verbal tests are fully automated. Stimuli are delivered via standardized text-to-speech voices and scored with a consensus automatic speech recognition (CASR) algorithm that combines multiple ASR engines to maximize accuracy.

  • CCAB scoring occurs instantaneously so that examiners can see test scores in real time. Verbal recordings are also stored for more in-depth phonological analysis.

Consensus Automated Speech Recognition

  • Multiple automated speech recognition (ASR) engines produce automatic transcriptions of verbal test responses.
  • Transcriptions are algorithmically aligned to produce the best consensus ASR transcript, mean word timestamps, and test scores.

Matthew is a software engineer at NBS. He primarily contributes to the development and timing validation of Presentation, the stimulus engine used in the CCAB.

 

Matthew’s background is at the intersection of technology and science, where he develops tools that scientists can rely on to perform ground-breaking research.

After co-founding NBS, Mr. Pebler created Presentation®

— the most powerful stimulus delivery software system for neuroscience, which has advanced the research of tens of thousands of scientists around the world for 20 years. He continues to utilize his 24 years of software development experience to ensure a solid foundation for every piece of technology NBS creates.

 

Mr. Pebler has a BS and MS in physics, from Yale and UC Berkeley.

Mr. Kahly serves as Research Associate at NBS, where he is responsible for ensuring the smooth day-to-day operation of NBS’s research initiatives.

After finishing her degree in Cognitive Psychology at UC Santa Cruz, Dr. Geraci joined NBS as a Content Developer in 2005. She has learned and grown with the company, honing her research skills, programming, and business acumen to become Director of Product.

Dr. Geraci has overseen the addition of myriad Presentation features over the years and continues to innovate with the development of CCAB testing and advanced data analysis.

Dr. Hall joined NBS as the Research Operations Director in 2021, and oversees research initiatives and the development of the CCAB.

 

During her graduate studies in linguistics at Northwestern University, Dr. Hall obtained extensive training in conducting behavioral experiments, with a focus on psycholinguistics and the representation and processing of syntactic constraints. Currently, Dr. Hall is focused on making cognitive testing more accessible to under-served populations, including leading translation initiatives to bring the CCAB to speakers of varied languages.

Dr. Woods is a co-founder and CEO of NBS who has helped direct the development of Presentation® software for the past 20 years.

During Dr. Woods’s long research career in cognitive neuroscience at UC Davis and the VA, he developed early versions of selected CCAB tests.

 

In 2017, Dr. Woods moved to NBS where he is currently CEO and the PI on an NIA-funded SBIR grant that supports normative data collection using redesigned CCAB tests that incorporate consensus ASR, neural text-to-speech, and tele-medical control through the CCAB Examiner interface.
