Description of Research Project: 
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.
Description of Student Responsibilities: 
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.

Perceptual Learning: Teaching with Computers

Description of Research Project: 
How do learners get better at searching, organizing and interpreting their visual world? Do the same processes that underlie perception of movement in sport, discovery in art, facility with puzzles and other forms of visual expertise also underly such practical skills as fluency in mathematics or proficiency in medical diagnosis? The current study is concerned with basic research in perceptual learning and object recognition. In addition we attempt to isolate and train visual skills using computer software that dynamically adapts to a learner's mental state.
Description of Student Responsibilities: 
Research assistants would help in the collection of data by running subjects at least 7 hours per week. Opportunities would be provided for assistants to collaborate in the generation of new experiments, analysis of data, and independent research. Experience with programming is a plus, but not required. Psych 120A or B are highly recommended.

Description of Research Project: 
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.

Contact Name: 
Dr. Zili Liu
Room Number:

Phone: 
310-267-4683
Description of Research Project: 
This National Science Foundation sponsored research investigates how the brain encodes into memory visually perceived scenes and objects (e.g., faces). Counter-intuitive predictions, with promising pilot data, will be tested.
Description of Student Responsibilities: 
Responsibilities include scheduling experiments on experimentrix, conducting the experiments, and debriefing the participant after each experiment.
