Which Way Does Time Flow? A Psychophysics-Grounded Evaluation for Vision-Language Models

A recent study highlights the limitations of modern vision-language models (VLMs) in understanding temporal information in videos. Researchers introduced a new benchmark called AoT-PsyPhyBENCH, which challenges these models to determine whether a video clip is played forward or backward. This evaluation is crucial as it sheds light on the models' ability to process temporal cues, an area that has been largely overlooked. Understanding how VLMs handle time could lead to significant improvements in their performance across various multimodal tasks.
