Despite this limitless capacity, we cannot process every piece of information provided to us or store this information in our long-term memory. The reason for not being able to utilize the whole capacity of the brain is still a question to be answered. However, researchers are trying to explain how brain functions physiologically and cognitively to process information. While neuroscientists are trying to answer the puzzling questions about the physiological functioning of brain, cognitive researchers study cognitive information processes. Both types of research provide critical information about human learning processes and in particular the ways of integrating multiple modes into user interface design and the effects of this integration on information processing. Cognitive psychologists drew attention to limited capacity of human brain and the impor- tance of selective utilization of users’ cognitive resources for effective presentation (Sweller, Serkan Özel Bogazici University, Turkey Utilizing Cognitive Resources in User Interface Designs ABSTRACT This chapter focuses on multiple representations and cognitive perspective about presenting information via different modes in user interface design. Research studies indicate that providing accurate represen- tations increases users’ recognition of information. Moreover, presentation of one concept in multiple modes improves concept acquisition. Developing an understanding of how concept acquisition occurs requires knowledge about cognitive information processing and brain functioning. Scientifc studies related to brain functioning will enlighten the path in front of cognitive psychology while the cognitive psychology research will advance the knowledge base on information processing.
