CAMCI®-Research Overview


CAMCI-Research is a customizable battery of computerized tasks to assess cognitive performance. Computer-administered and self-paced, this investigative tool allows researchers to arrange a protocol of tasks to collect accuracy and reaction time data for comparison to normative data. There are 9 behavioral tasks included in the complete CAMCI-Research battery. Additionally, a series of self-report questions may be presented to gain information from the participant regarding factors that could affect the participant's performance on the CAMCI-Research tasks (e.g., perceived memory loss, alcohol use, depression, anxiety, etc.).

 

CAMCI-Research accurately assesses cognitive performance using standard neuropsychological tests of memory, attention, and executive ability modified for computer administration. Plus - an innovative Virtual Environment task tests domains, such as incidental memory, not easily assessed using paper-pencil tests. Computer-administered tasks ensure standard administration and scoring, avoiding inter-site and inter-examiner variability.

 

The CAMCI-Research application allows the researcher to design protocols by selecting and arranging tasks to run from the battery provided. The researcher may define instructions to be presented to the examiner prior to or following a test session, or choose to present screens to welcome or dismiss the subject. Customization also allows the researcher to select events to assess the suitability of the computer's timing for data collection and the accuracy of the input calibration, or to require a security pass code to limit the accessibility to reports after a test session is completed.

 

Results are available immediately following each test session, including comparison of task measures to age and/or education adjusted normative data. Performance on each CAMCI-Research task is recorded in trial-level and summary task-level data files to allow further, detailed analysis.

 

Intended use: The CAMCI-Research product is for research, investigational, or educational use only. CAMCI-Research does not offer a medical diagnosis.

CAMCI®-Research FAQs


Q: How does CAMCI-Research work?

No test administration training required! The CAMCI-Research tasks are computer-administered, and completed by the subjects at their own pace, using a digitized pen, a mouse, or the subject's finger for input. Data is automatically logged, scored, and compared to normative data. A summary report provides measures and values per task in a clear and effective report format. The researcher customizes the selection of tasks to be presented.

 

Q: What does CAMCI-Research test?

CAMCI-Research includes tests of attention, memory (verbal, non-verbal, functional and incidental), executive function, and processing speed. A virtual environment task provides an innovative approach to testing domains, such as incidental memory, not often assessed by paper-pencil tasks. Self-report questions capture additional information from the participant, such as perceived memory loss and alcohol use, that could influence interpretation of the results.

 

Q: In what ways can a test session be customized?

An easy-to-use protocol creation wizard makes it simple to customize your study with the following features:

  • Select and arrange tasks within a protocol
  • Select mode of input (mouse, pen, touch)
  • Add or edit session level variables
  • Add and define pre- or post-test instructions for examiners
  • Select to present welcome or dismissal screens
  • Select form of stimuli from equivalent options
  • Assess suitability of computer timing
  • Access accuracy of input calibration
  • Select security pass code to limit accessibility to PC
  • Set location for saving projects and data
  • Define volume level

Additionally, different forms of the same tasks exist in extended versions. During protocol creation, normative data can be selected for comparison against data collected in the study.

 

Q: Can experiments be customized?

CAMCI-Research experiments may not be modified. The CAMCI-Research application allows the researcher to design protocols by selecting and arranging tasks to run from the battery provided. The researcher may define instructions to be presented to the examiner prior to or following a test session, or select to present screens to welcome or dismiss the subject. Customization also allows the researcher to select events to assess the suitability of the computer's timing for data collection and the accuracy of the input calibration, or to require a security pass code to limit the accessibility to reports after a test session is completed.

 

Q: Is the test available in languages other than English?

CAMCI-Research is currently only in US-English. The task instructions and stimuli used in CAMCI-Research are being developed in other languages, but are currently not available.

 

Q: What is the difference between CAMCI-Research and CAMCI-Clinical?

CAMCI-Research is a fully customizable task battery that is intended for education and research uses only. CAMCI-Clinical is intended as a computerized assessment tool to contribute to the clinical assessment of cognitive function in older adults. For more information on CAMCI-Clinical contact us.

 

Q: What tasks are included in the CAMCI-Research battery?

There are 9 behavioral tasks included in the complete CAMCI-Research battery. Additionally, a series of self-report questions may be presented to gain information from the subject regarding factors that could affect the subject's performance on the CAMCI-Research tasks (e.g., perceived memory loss, alcohol use, depression, anxiety, etc.).

  • Orientation to Date
  • Simple Reaction Time
  • Digit Span Forward
  • Digit Span Reverse
  • Go/No Go
  • Word Recall
  • Verbal Recognition
  • Recurring Pictures
  • Virtual Environment

The Virtual Environment Task includes three subtasks; intersection accuracy, recall, ATM accuracy.

 

Q: Are there alternate forms?

There are currently two forms of CAMCI-Research tasks available with base and extended versions.

 

Q: What normative data is available?

Form A - 60-90+ years

Form B - 60-90+ years

Form A-Extended - 18-59

The CAMCI-Research normative data was collected on a predominantly Caucasian sample of adults, with a minimum education level of 8th grade, living in western Pennsylvania. Care should be exercised when extrapolating results to other populations. CAMCI-Research has not been validated for use with patients suffering from major psychiatric disorders, such as schizophrenia and bipolar disorder, or for patients having a current diagnosis of dementia or other disorder causing impairment of cognitive ability sufficient to prevent understanding of task instructions.

 

Q: What kind of information does the summary report provide?

CAMCI-Research provides a summary report at the end of the task, including accuracy and response time measures per task run, task measure z-scores as compared to normative data, and group means and standard deviations for the selected normative data set. The report also includes subject demographic data, data for any session level measures collected, and additional information relevant to a test session, including both session notes and subject responses to screening questions.

 

Q: Can I get a copy/demo of CAMCI-Research?

A demo is currently not available for CAMCI-Research, but please refer to our gallery for pictures and descriptions of the interface and the tasks within the battery.

 

Q: Are participant's results kept confidential?

During creation of a protocol, the user may select to require a pass code following a test session, which prevents unauthorized access to data and reports. This ensures both confidentiality of data and results, and prohibits subjects from viewing their own results after a test session is completed.
