The Psycholinguistics Lab in OSU Linguistics consists of a group of dedicated researchers, students and a technical staff. Members of our lab share interest in a broad range of issues in sentence/discourse processing, and discuss each ongoing project actively inside and outside the regular lab meetings. Each member of the lab benefits from constant feedback from the others throughout the development of study. As a result, our lab is generating a large number of collaborative research. Our Psycholinguistics Lab is equipped with two eye tracking systems (ASL 6000 & Tobii 1750) and three soundproof booths with computers for recording voice responses and button/key responses. The ASL eye tracking system incorporates the detection of head rotations for tracking the eye movements of participants, and thus allows experiments involving real-world objects (that participants can touch and move) as well as monitor-based visual search tasks. The Tobii eye tracking system is based on simultaneous detection of the locations of two pupils and is set up for monitor-based experiments. The short calibration time on Tobii system makes it especially useful for examining children's eye movements. Each soundproof booth has a high- quality microphone and preamplifier which allows collection of high- quality voice data for production studies. Most of our ongoing experiments use Eprime software for the presentation of stimuli.Computational Linguistics Lab
The department has a Laboratory and Computing Committee with a significant budget that pays for the hardware and software necessary to do first class teaching and research in computational linguistics. Currently the department has multiple compute servers as well as PCs and Macs for communal use; a special purpose computer lab designed for teaching and research; and state-of-the-art experimental facilities such as eye-trackers. All the department computers are linked to the department high speed ethernet network, thus providing access to the department's superb computing support staff. The computational linguistics lab maintains an LDC subscription and a file server that gives fast network access to all necessary corpora. The SLaTe lab in CSE shares the LDC subscription and maintains a Linux server pool designed to support research on speech recognition and large scale NLP. The Ohio Supercomputer Center has a 1,000 node Linux cluster for extremely large scale scientific computation.Phonetics Labs
There are two Phonetics Labs within the department, with some common space (e.g., a recording room with a large double walled recording booth and a small "conference" room for lab meetings), as well as separate spaces for running perception experiments and for housing equipment for recording and analyzing productions by children and adults in a variety of off-campus sites, including the OSU Child Care Center and schools and homes in many other places such as Tokyo, Hong Kong, and Thessaloniki.Members of the Perception Lab work on projects exploring perceptual dialect classification, the relationship between variation and speech intelligibility, and so on. Their lab space is equipped with five computers set up with button boxes and keyboards to record subjects' responses.
Members of the Paidologos Lab who record children and adults off-site upload their data to a project server that is maintained by a part-time systems adminstrator.
