Acute stress significantly impairs decision-making by altering brain activity patterns.
Acute stress demonstrably impacts cognitive processes involved in decision-making, as evidenced by measurable changes in brain activity.
IEEE Access · 2024
Key Findings
- 01EEG and fNIRS are viable tools for detecting acute stress during decision-making tasks.
- 02Acute stress alters brain activity patterns associated with decision-making.
- 03There is a need for standardized methodologies in stress induction and measurement in decision-making research.
Application
Design takeaway
When designing for situations where users might experience acute stress, consider how cognitive load and decision-making accuracy can be affected, and explore ways to provide support or simplify tasks.
How to apply
In the design of critical systems (e.g., aviation, emergency response), consider incorporating features that simplify complex decisions or provide clear, concise information when stress levels are likely to be high.
Project actions
- 01When researching user behaviour, consider how environmental stressors might influence outcomes.
- 02If using physiological data, ensure clear protocols for data collection and analysis.
Method & Evidence
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.
