Cognitive Science is the scientific study of the mind, brain, and intelligence, particularly as it relates to mental abilities such as reasoning, decision making, memory, learning, attention, language, perception, and motor control. This young and emerging interdisciplinary field lies at the intesection of psychology, computer science, philosophy, neuroscience, and linguistics. Cognitive scientists aim to discover fundamental principles that underlie all forms of natural and artificial intelligence, from high-level reasoning to perceptual-motor behavior. The pursuit of this alluring and ambitious goal requires the use of various methods, tools, and perspectives. Cognitive scientists build computational, formal, and quantitative models, conduct experimental research on behavior, and investigate neural mechanisms. The knowledge gained by cognitive scientists has numerous real-world applications, such as the design of robots, speech recognition systems, automated reasoning systems, and human-computer interfaces.
As one of the few genuine departments of cognitive science in the world, the faculty offers unique and exciting opportunities for students to focus on the scientific study of mind, brain, and intelligence. Staffed by a core of cognitive-science oriented psychologists, philosophers, and computer scientists, the department complements Rensselaer’s traditional strengths in science, engineering, and technology, and is widely regarded as a leader in the area of computational cognitive modeling. The department offers a highly selective Ph.D. program in Cognitive Science and B.S. programs in both Psychology and Philosophy. Faculty research interests include computational cognitive modeling, artificial intelligence, human and machine reasoning, computational linguistics, perception and action, theoretical neuroscience, cognitive robotics, cognitive engineering, and advanced synthetic characters.
Research Innovations and Initiatives
Graduate training in Cognitive Science emphasizes research, modeling, and building of integrated cognitive systems. Within this broad scope the department has special strength in the following areas.
At Rensselaer AI is taken to be the field devoted to either engineering computational systems whose behavior is on par, or at least approaches, that of humans; or computational systems whose intelligence is regarded to be at once high by humans but qualitatively different than the capacities seen in humans. Of course, AI can be pursued in different ways. Here, given how AI is viewed, guidance as to how to engineer the relevant systems often comes from careful study of the cognitive powers of humans, including what forms of intelligence those powers classify as truly impressive.
Cognitive Engineering is the application of cognitive science theories to human factors problems. Putting cognitive theories to the test of real-world applications is a means of maintaining a focus on the truly important cognitive issues. At Rensselaer, cognitive engineering has two components; (1) research directed at solving applied problems, and (2) research directed at developing engineering tools that others with less cognitive training can use to solve applied problems.
Cognitive robotics is a field devoted to engineering robots whose actions are a function of knowledge, belief, preferences, plans, and so on. In short, a cognitive robot acts on the basis of the things that underlie the actions of human beings.
Computational Cognitive Modeling
Understanding an integrated cognitive system can be very complex. The possibilities for interaction among cognitive, perceptual, and action operations is astounding. The interplay of each of these with the other and with the external world cannot be simply predicted. Computation cognitive models provide a vehicle to manage this complexity with the goal of making progress towards understanding how integrated cognitive systems effect and are affected by their environment.
We focus on language use that involves a deep understanding of semantics and intent. Work in the department includes integrating language parsing with reasoning about the world and people’s beliefs and desires; logically controlled languages for learning by reading; and using human language to retrieve and analyze information from heterogeneous sources.
Human and Machine Reasoning
Foci include logic-based and knowledge-based AI, theorem-proving, and psychology of reasoning. The multi-disciplinary group of researchers involved is known as Rensselaer Reasoning Group, which works out of the Rensselaer AI & Reasoning (RAIR) Lab.
Perception and Action
This area of research focuses on perception with an emphasis on its role in the performance of both routine and skilled goal-directed action. Current research topics include visually guided locomotion in real and virtual environments, the coordination of eye and hand movements, and the integration of perception and action with higher-level cognition (e.g., learning and attention). At Rensselar, these topics are investigated from various theoretical perspectives, including ecological psychology, dynamical systems theory, and computational cognitive modeling.
At the undergraduate level, the department maintains separate programs in cognitive science, philosophy, and psychology, leading to the Bachelor of Science degree in each discipline, respectively. An important goal of the undergraduate program is to prepare students for careers in the rapidly growing “Information Economy,” marked by the confluence of computation and cognition.
Dual majors are available in all (philosophy and psychology) department curriculum areas.
Majors that may be combined with philosophy to form a dual major include computer science, physics, mathematics, biology, architecture, and various engineering majors (e.g., computer systems engineer). These dual programs serve the needs of those students desiring to combine the virtues of a liberal arts education with those of science, architecture, or engineering to achieve an education that is practical, stimulating, and diverse.
As an example of how such dual majors are structured, a student majoring in physics and philosophy would meet the requirements of the physics curriculum and take eight courses in philosophy. These might include PHIL 2130 Introduction to Philosophy of Science, PHIL 4360 Philosophical Problems of Space and Time, and PHIL 4310 Scientific Revolutions. A student majoring in computer science and philosophy would meet the requirements of the computer science curriculum and take eight philosophy courses that might include PHIL 2140 Introduction to Logic, PHIL 4260 Philosophy of Artificial Intelligence, and PHIL 4420 Computability and Logic. For a mathematics-philosophy dual major, key courses might include PHIL 4380 Philosophy of Mathematics, PHIL 4140 Intermediate Logic, and PHIL 4440 Knowledge, and Rationality.
Dual majors with psychology may include computer science; electrical, computer, and systems engineering; and decision science and engineering systems. A dual major in management and psychology is also available. The Lally School of Management has established certain requirements that must be completed for this major in addition to those described above. For further information and a list of requirements for this dual major, see the Lally School of Management section of this catalog.
The Department of Cognitive Science provides a variety of minor programs within its curricula.
The Cognitive Science Department offers a Master of Science degree in Cognitive Science. The degree is open only to two groups of students. The first group is those who are already admitted to Rensselaer in a doctoral program. This includes students in the Cognitive Science doctoral program as well as students in other doctoral programs (e.g., Decision Sciences and Engineering Systems, Computer Science, and so on). Rensselaer doctoral students who desire a Master’s in Cognitive Science should contact the department directly. Other students able to obtain a Master of Science degree in Cognitive Science are those in our five-year program that combines the Bachelor of Science in Psychology or Philosophy with the Cognitive Science master’s. See co-terminal B.S./M.S. programs for more information.
Co-terminal B.S./M.S .Programs
Qualified students, in consultation with an academic adviser, may design a five-year program to complete requirements for the Bachelor of Science in Psychology or Philosophy and the Master of Science in Cognitive Science. An additional 30 credit hours are required beyond the B.S. degree. Students must apply to the program prior to or early in the first semester of their junior year. This is a research-oriented Cognitive Science program that allows students to focus on one of the department’s research areas. Prior to applying, it is expected that students will have taken introductory courses in cognitive psychology, philosophy of mind, and cognitive science, as well as been involved in one of the several research labs sponsored by department faculty.
The mission of the doctoral program in Cognitive Science is to train the next generation of world-class cognitive scientists and make seminal contributions to the field. In keeping with the interdisciplinary nature of cognitive science, this program trains students to integrate theories, methods, and tools from a variety of fields.
Because there are no traditional qualifiers, students become engaged in research from the beginning of their first semester in the program. Students work closely with individual faculty as well as teams of faculty, post-docs, and graduate students whose research interests include computational cognitive modeling, artificial intelligence, human and machine reasoning, computational linguistics, perception and action, theoretical neuroscience, cognitive robotics, cognitive engineering and advanced synthetic characters. There is a strong emphasis on building models of natural and artificial cognitive systems using formal, quantitative, and mathematical tools. The department has excellent research facilities, such as eye tracking equipment, an array of robotics equipment, and a large-scale immersive virtual environment lab. For information and guidance about applying to this new Ph.D. program, please contact Betty Osganian, Student Services Administrator at the undergraduate and graduate levels at firstname.lastname@example.org.
