Variables
Strengths & Limitations
Strengths
- +Comprehensive synthesis of existing literature.
- +Identifies potential technological tools for stress detection.
Limitations
It can be challenging to ethically and effectively induce acute stress in a controlled laboratory setting without causing undue harm or confounding results.
Reliability & validity
The reliability of findings is limited by the heterogeneity of methods across studies. Validity is challenged by the artificiality of laboratory stress induction and the complexity of interpreting neuroimaging data.
Think critically
How might the specific type of stress (e.g., time pressure vs. fear of failure) differentially affect decision-making processes, and how could design interventions be tailored accordingly?
Design Principles
"Design for cognitive resilience by accounting for the impact of acute stress on user performance."
Understanding how stress affects decision-making is crucial for designing systems and environments where users might operate under pressure. This insight can inform the development of user interfaces, training protocols, and support systems that mitigate the negative effects of stress.
What This Means for Your Design
When people are stressed, their brains work differently, which can make it harder to make good decisions. Tools like EEG can show these brain changes.

Paragraph starter
This systematic review by Abdalhadi et al. (2024) highlights that acute stress significantly impacts decision-making processes, with measurable alterations in brain activity detected via EEG and fNIRS. The findings underscore the importance of considering stress as a critical factor in user performance and system design, particularly in contexts where users may operate under pressure.
