Multimodal Large Language Models as Synthetic Participants in Video-Based Studies: An Evaluation

arXiv:2606.07541v1 Announce Type: cross Abstract: Multimodal large language models (MLLMs) have shown strong performance on objective tasks such as video understanding and reasoning. However, it remains unclear whether they can approximate subjective human responses, which depend not only on content comprehension but also on individuals' social contexts. To address this gap, we evaluate MLLMs as synthetic participants in an emerging task: assessing perceived sensory engagement with short videos. Grounded in the Perceived Message Sensation Value (PMSV) framework, we compare ratings from recruit

Why this matters
Why now

The rapid advancement and sophistication of Multimodal Large Language Models (MLLMs) are enabling them to not only understand objective information but also to simulate subjective human responses, pushing the boundaries of AI capabilities.

Why it’s important

This development indicates MLLMs can move beyond simple data processing to emulate nuanced human perception and social context, impacting fields reliant on human feedback and potentially accelerating the development of truly autonomous AI agents.

What changes

MLLMs can now be considered as viable synthetic participants for certain types of qualitative research, offering a faster and more scalable alternative to human recruitment for studies assessing subjective experiences.

Second-order effects
Direct

AI models will increasingly replace human participants in subjective research and evaluation tasks.

Second

This will accelerate the iteration and development cycles for products and services that rely on user feedback.

Third

The definition of 'human-like' intelligence will become increasingly blurred as AI systems demonstrate capabilities previously thought to be uniquely human.
