When learning complex material online, individual work may be more effective than group collaboration due to increased cognitive load. This human factors research insight is drawn from a 2026 study published in Frontiers in Psychology. Using Experimental study with 85 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing online learning experiences for complex subjects, prioritize features that minimize extraneous cognitive load for individual learners, and carefully consider the structure and support for collaborative activities.

Key Findings
- 01Low-complexity tasks resulted in higher performance, lower cognitive load, and higher efficiency compared to high-complexity tasks.
- 02Collaboration improved performance on low-complexity tasks but reduced performance on high-complexity tasks.
Application
Design takeaway
When designing online learning experiences for complex subjects, prioritize features that minimize extraneous cognitive load for individual learners, and carefully consider the structure and support for collaborative activities.
How to apply
When developing online courses or collaborative tools, conduct user research to understand the cognitive demands of different task types and consider offering flexible learning modes (individual or group) based on task complexity.
Project actions
- 01When designing an online tool, think about how much mental effort (cognitive load) a user will need.
- 02Test if your design helps users learn better when they work alone versus when they work in a group, especially if the task is difficult.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Investigated a relevant aspect of online learning.
- +Used a controlled experimental design.
Limitations
The findings might not apply to all types of online tasks or all user demographics. The specific design of the online environment and the collaboration tools used could significantly influence the outcomes.
Reliability & validity
The study's reliability could be enhanced by using standardized measures for cognitive load and performance. Validity is supported by the experimental manipulation of key variables, but ecological validity might be limited by the artificiality of the online tasks.
Think critically
How might the design of the online interface itself (e.g., layout, communication tools) mediate the observed effects of collaboration on cognitive load and performance?
Design Principles
"Cognitive load management is crucial for effective online learning, and the optimal learning strategy (individual vs. collaborative) is contingent on task complexity."
This research highlights that the benefits of collaboration are not universal and depend heavily on the nature of the task and the learning environment. Designers of online learning platforms and collaborative tools need to consider how task complexity impacts user cognitive load and performance.
What This Means for Your Design
Working alone online can be better for hard stuff, but working with others might be good for easy stuff.
How to use in your project

Paragraph starter
Research indicates that the effectiveness of online collaboration is significantly influenced by task complexity, with individual work often proving more beneficial for high-complexity tasks due to reduced cognitive load. This suggests that design interventions for online learning environments should consider offering tailored support for individual deep work on challenging subjects, rather than assuming universal benefits from collaborative approaches.
