Strengths & Limitations
Strengths
- +Utilized a large participant sample size.
- +Compared results against established 'gold-standard' measurement equipment.
Limitations
The app's synchronization was described as 'fair,' indicating that while reliable, it might not be as precise as dedicated laboratory equipment in all scenarios.
Reliability & validity
The study established reliability through cross-correlation with gold-standard equipment, indicating good validity for measuring key metrics like reaction time and lapses.
Think critically
How might the 'fair' synchronization of the app impact the precision of design decisions based on its collected data, especially in high-stakes applications?
Design Principles
