Experiment Participation

Volunteering for studies at the CVL lab will help us to gain a greater knowledge of the human perceptual and cognitive process.

If you’d like to be notified of opportunities to participate in CVL studies, please contact Hongjing Lu hongjing@ucla.edu .

Research Assistantship in Cognitive Science (Psych 196B, Psych 199)

Students will be involved in conducting experiments, data collection and organization. Students also have the opportunity to aid in the design of new experiments and the development of computational modeling. Students are encouraged to be involved in the new experiments for the preparation for the Psychology Undergraduate Research Conference (PURC) at UCLA.

Title of Research Project: Prior knowledge in high-level cognition

We study predictive, diagnostic and analogical reasoning from a computational perspective. We are especially interested in what prior knowledge humans assume in making an inference from few examples. Our research aims to develop computational models for a range of reasoning experiments, and assess the validity of computational models by comparing their predictions with human performance in controlled experiments.

Title of Research Project: Human action perception

We are interested in how the visual system represents and identifies human action in a motion sequence. It is crucial to perceive and interpret human body movements to be able to interact with other people well. This research explores the underlying information use of visual input in a series of psychophysical experiments

Title of Research Project: Motion perception

We study motion perception for cases ranging from simple translational motion, to complex radial/circular motion, to the sophisticated biological motion on which human actions are based. The integration of psychophysical experiments with computational models assists us understanding (1) how humans represent different motion patterns as structural complexity increases; (2) the limitations of human motion processing; (3) the strategies the human visual system employs to complete different tasks (e.g., motion segmentation, motion grouping, and tracking over time).
