Neurapulse Test
Neurapulse tests include tasks designed to measure:
- Reaction time
- Judgment
- Working memory
- Fine motor control
- Mental flexibility
Task Types
The following tasks have been subject to various forms of validation. Neurapulse tasks are calibrated to real-world driving outcomes, and can predict when a test taker is at risk of driving unsafely. Test takers should perform each task in a safe environment free from distractions.
If the test taker lifts their finger during a task, a prompt will appear to continue. All tasks should be completed as quickly and accurately as possible.
- Reaction Time:
This task measures the test taker's ability to react quickly and accurately to simple stimulus.
Healthy reaction time is the most basic competency tested for measuring risk in safety-sensitive environments. It's important for simple tasks that require immediate responses. For example, when a driver is on the road, they need to be able to respond quickly and accurately to their environment.
- Stage 1: Connect dots quickly and accurately
- Stage 2: Similar to Stage 1 with but with more dots
- Mental Flexibility (Part 1):
This task measures the test taker's ability to be make judgements quickly and accurately.
Attention-based tasks can be used for measuring a test taker's judgement as they excercise their working memory. This ability is important for safety-sensitive environments that require sustained focus and attention to detail. For example, when a driver plans for a left turn in an intersection, they need to accurately judge the flow of traffic.
- Stage 1: Connect numbered dots in the required sequence (1, 2, 3, 4, etc.)
- Stage 2: Similar to Stage 1 but with more dots
- Mental Flexibility (Part 2):
This task measures the test taker's mental flexbility while increasing the challenge on their working memory.
Mental flexibility tests are crucial in determining impairment risk. When test takers must maintain full attention (keeping a sequence in mind) while planning actions, making quick and accurate judgments becomes highly challenging. Many safety-sensitive roles involve similar complex, sequential tasks where perfect execution is critical for safety.
- Stage 1: Connect dots in the required alternating sequence (1, 25, 2, 26, etc.)
- Stage 2: Similar to Stage 1 but with more dots
