Task parameters
15 built-in items across three difficulty levels. Items are randomised per session. No time limit — participants respond at their own pace.
This is a researcher preview. No participant data is recorded.
Simulated participant view
A nonverbal reasoning task where participants complete a missing element in a visual pattern.
No data is recorded
One incomplete matrix item with multiple answer options shown underneath.
Useful for lower-frequency cognitive profiling and studies that need a brief reasoning measure.
Not ideal for high-frequency EMA because each item is relatively cognitively demanding.
Use short item sets and alternate forms to reduce repeated exposure bias.
Better suited to baseline or periodic assessments than daily sampling.
