Program tanımlarıObjectives
Cognitive Science is defined as the scientific study of mind from an interdisciplinary perspective. The objective of our graduate programs is to offer students of different backgrounds breadth of knowledge and research techniques in a wide range of areas in Cognitive Science, including but not restricted to the areas of expertise of our staff.
The training we offer in Cognitive Science is interdisciplinary and theoretically oriented. Four disciplines are represented in the graduate programs of Cognitive Science at METU. Cognitive Psychology studies cognitive processes such as memory, attention, perception and reasoning through empirical research on human behavior. Linguistics investigates the nature of human language and its manifestation as a mental ability. Computer Science creates computational models of cognitive processes for purposes of understanding similar abilities in humans and designing intelligent systems. Philosophy addresses questions about the essential nature of mind, knowledge, representation, and language.
Career Opportunities
Language technology, innovative uses of computers, man-machine interfaces, academic track on Cognitive Science or related disciplines, such as Computer Science, Linguistics, Psychology, Philosophy.
Program Structure
Courses are grouped into four tracks. These are Computer Science, Linguistics, Psychology, Philosophy (see the curriculum). The advisor of each student will be responsible for guiding the student in taking the necessary courses, by considering the courses that the student has taken in the past. In order to receive a PhD degree, the total number of courses and credit hours taken in the master's and doctoral programs may not be less than 17 courses and 51 credit hours.
Students must take COGS 501 - Linguistics and Formal Languages and COGS 502 - Logic and Programming courses.Students who have their undergraduate degree from Computer Science are exempted from COGS 502. Students with other undergraduate degrees who believe that
they can be exempted from this course because of their knowledge of the content of the course must see the course instructor.
Those students who are granted exemption from must courses must take an extra elective for each course replaced as such.
Students should take at least one restrictive elective from each track. All courses are offered by METU, except where noted.
