The Cognitive Area encompasses six broad areas and emphasizes laboratory and neuroimaging research and cognitive modeling in each:
Memory is a component of cognitive architecture that underpins people's ability to perform practically all higher level processing. Within the program, we study human memory using behavioral, neuroscientific and computational modeling methodologies. We focus on short and long term episodic memory and memory for sentences and text. The impact of age and disorders on memory processes is also strongly represented.
Perception and Action
Perception and action have a reciprocal relationship in that perception guides action, which in turn influences perception. Topics of research in this area involving numerous faculty in psychology and engineering include sports activities, vehicular control, the analysis of 3D structure from 2D image data and the recognition of objects and faces. A central theme in all of these areas is to develop computational models that can simulate the essential characteristics of perceptual and motor performance, and to test those models with appropriate behavioral experiments.
Language and Speech
Research at Ohio State spans the spectrum of inquiry, from basic processes of phonetics and phonology, through morphological and lexical phenomena, to the study of syntax, semantics and discourse. Using event related potential laboratories, we investigate the time course of syntactic processing. Using behavioral paradigms, we explore the way in which people recognize spoken words, resolve anaphora and perform inferential processing. Computational modeling and the analysis of language corpora play a central role in our approach to psycholinguistics. We also have strong ties to the Ohio State Linguistics Department, one of the top programs in the US.
Many of the faculty in the Cognitive and Quantitative programs believe that insight into cognitive processes can only be derived through the construction and appreciation of computational models that enforce consistency and reveal the impact of interactions among component processes. At Ohio State, we place a strong emphasis on development, analysis and evaluation of cognitive models across a wide range of domains of inquiry.
Exploration of the manifestation of cognitive processes in the brain is made possible by neuroimaging techniques, in particular functional magnetic resonance imaging (fMRI) and electroencephalography (EEG). The Siemens 3T Trio magnetic resonance imaging Total Imaging Matrix (TIM) system at the Center for Cognitive and Behavioral Brain Imaging (CCBBI, http://ccbbi.osu.edu) is available for structural and functional MRI studies. It is equipped with a state-of-the-art projection system, Eyelink II eye tracker, and MR compatible high-definition audio system. Several EEG setups are also available.
Research in cognitive development focuses on the development of attention, learning, memory, language and concept acquisition, and interactions among these components. Faculty study cognition in infants and young children using preferential looking, habituation, EEG, and microgenetic approaches, as well as traditional experimental techniques and physiological measures.
