Integration of Voice Recognition
Free Recall in Remote Administration
e.g. Verbal Learning Tasks
Assess Spoken Responses in Remote Administration
e.g. fluency and sentence recall tasks
Drawing Capabilities
Administration is designed for use with touchscreen technologies. This allows the participant to perform tasks that require drawing. e.g. trail making and figure copying tasks. Drawing results are saved as PNG files for visual inspection. Components of drawing are also saved for more in-depth analysis of drawing component speed, variability (shakiness), etc.
Adaptive Difficulty
Adaptive difficulty protocols are available for task administration. This allows for tasks to adjust their difficulty based on participant responses. e.g. digit span
Modifiable Parameter Sets
Task components load up easily modifiable parameter sets. Therefore, the task component code does not need to be modified to change parameter values. This allows the reuse of the task component code for multiple situations. Parameter sets include different versions of the same test, for instance the Golden or the Victoria versions of the Stroop. It is also possible to turn on/off the welcome or thank you screen for a test. This facilitates creating screening batteries.
Immediate Modifiable Scoring
Scoring of responses in incorporated into the task administration code. The result is that at task completion summary scores are calculated and stored in the database along with the raw data. This allows different scoring approaches based on the parameters used for task administration. e.g. Stroop with time to complete 24 trials vs. number of trials completed in 45 seconds.
Modifiable Languages
Once translated, the instructions and any language based stimulus (e.g. words) are easily changable through the modifiable parameters. This allows the user to choose the language of administration, and even the accent spoken by the pre-recorded audio stimuli.
Verbal Stimuli
Word and number stimuli are pre-recorded using text to speech technology. This allows the choice of language, accent, and speaking speed. The user can setup their tasks to match language and accent to any local population.
Cognitive Batteries
Multiple tasks may be selected and ordered into batteries. Batteries may differ based on the task components included, or may include the same task components but with differing parameters. An example, may be short and long versions of the same task components. Therefore, each tasks component requires its own set of parameters that describe the number of trials, timings, etc.
Audio Assessment
This is to ensure that participants can hear any audio and that their speakers are functioning properly.
Speaking Assessment
This is to ensure that the speech recognition is working properly and that the participant's microphone is functioning.
Language
All introduction, instruction, and thank you text can be translated into other languages and loaded via configuration files.
Summary
The use of modifiable parameters and batteries means the end user does not need to modify any of the code that delivers the task components. They only need to develop their own personalized batteries. Once multiple batteries are developed they are administered based on a URL parameter in the hyperlink provided to participants.
