Novice interpreters' performance in consecutive interpreting is a complex interplay of task difficulty, their second language proficiency, anxiety levels, and working memory capacity. This human factors research insight is drawn from a 2026 study published in Acta Psychologica. Using Experimental study with 39 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers of training or support tools for interpreters should consider a multi-faceted approach that addresses cognitive load, individual linguistic and psychological factors, and the specific demands of the interpreting task.
Task complexity and individual differences significantly impact novice interpreter performance.

Key Findings
- 01Increased task complexity led to a decline in informational accuracy and fluency.
- 02Target-language output quality remained relatively stable even under high task load.
- 03Higher L2 proficiency positively correlated with accuracy and language quality.
- 04Anxiety negatively impacted fluency, but this effect was reduced under the most demanding tasks.
Application
Design takeaway
Designers of training or support tools for interpreters should consider a multi-faceted approach that addresses cognitive load, individual linguistic and psychological factors, and the specific demands of the interpreting task.
How to apply
When designing training simulations or performance support tools for interpreters, vary the difficulty of the simulated tasks and incorporate elements that allow users to practice managing anxiety and working memory.
Project actions
- 01When designing a task for users, consider how its complexity might affect their performance, especially if they are new to it.
- 02Think about individual differences like skill level or stress tolerance and how they might interact with task demands.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Investigates a complex interplay of factors relevant to human performance.
- +Uses a controlled experimental design to assess performance metrics.
Limitations
The study was conducted with novice interpreters, so the findings might not apply to experts. The specific language pair used could also be a factor.
Reliability & validity
The study's reliability would depend on the consistency of the task complexity manipulation and the measures of performance and individual differences. Validity would be supported if the chosen measures accurately reflect consecutive interpreting performance and the targeted cognitive/affective traits.
Think critically
How might the findings regarding anxiety's dual role under high cognitive load inform the design of adaptive user interfaces that dynamically adjust complexity based on user stress levels?
Design Principles
"Cognitive load management and individual difference accommodation are essential for optimizing performance in complex, high-stakes communication tasks."
Understanding these factors is crucial for designing effective training programs and support systems for individuals undertaking cognitively demanding communication tasks. It informs how to structure tasks and provide interventions to mitigate performance degradation.
What This Means for Your Design
When interpreters are new, making the task harder makes them mess up more and speak slower, but the actual words they use stay about as good. Being good at the language helps a lot, and even though being nervous usually makes people speak less smoothly, it doesn't make it as bad when the task is super hard.
How to use in your project
- 1.Use this research to justify why you are controlling for or investigating specific user characteristics (like skill level or anxiety) in your design project.
- 2.Reference this study when discussing how task complexity can impact user performance and how to mitigate negative effects.

Paragraph starter
This study by Jiang and Lv (2026) highlights that novice interpreters' performance in consecutive interpreting is significantly influenced by task complexity, which can lead to decreased accuracy and fluency. However, individual factors such as second language proficiency and anxiety play a crucial role, with higher proficiency improving performance and anxiety's negative impact on fluency being mitigated under high cognitive load. This underscores the importance of considering both task design and individual user characteristics when developing systems or training for demanding cognitive tasks.
