Trinity's Psychology Department offers the state-of-the-art equipment required for comprehensive study. Department computers are used for laboratory work and classroom demonstration. For example, both Introduction to Psychology and Psychotherapy (an advanced course) use the campus computer network for class discussion. The network provides on-line access to the College library's catalogue of 900,000 books and periodicals, and, with hookups in every dorm room and faculty office, connects Trinity students to information sources around the world through the Internet.
