Welcome to module 7, lecture number 23 of the Usability Engineering playlist on YouTube by Prof. Debayan Dhar from the Department of Design Engineering at the Indian Institute of Technology Guwahati. In this module, we will be discussing the Cognitive Issues related to humans. Understanding these cognitive issues is crucial for designing interfaces that can enhance the capacity of users in achieving their goals.
In this video, we will delve into cognition, cognitive processes, cognitive load, various theories, cognitive frameworks, and models that can help us design more effective systems for our customers and users. We’ll start by understanding the concept of cognition, which refers to the mental actions or processes involved in acquiring, maintaining, and understanding knowledge through thought, experience, and senses.
Cognition is a broad term that encompasses various mental activities and processes. It is a mental activity associated with obtaining, converting, and using knowledge. The word cognition is derived from the Latin word cognoscere, meaning “to know” or “to come to know.” It plays a crucial role in acquiring, maintaining, and comprehending information and transforming it into knowledge.
Within cognition, thinking is a main component and refers to mental activities such as coming to a decision, reaching a solution, forming a belief, or developing an attitude. These processes have significant implications in the context of designing for our users. Decision making, belief formation, and attitude development are vital aspects of the design process and can greatly influence product adoption and user satisfaction.
As designers, it’s essential to understand the barriers, frustrations, and pain points that may affect user beliefs and attitudes. By identifying and addressing these factors, we can ensure that the products we design are adopted with a higher degree of satisfaction. Cognitive processes such as attention, language, learning, memory, perception, and thought play crucial roles in shaping user experiences and interactions.
Attention, for example, allows users to focus on specific design stimuli, and language enables effective communication and thought articulation. Understanding users’ attention and language development can be achieved through techniques like eye movement recorders, which provide insights into user engagement, gaze patterns, and design cue influences.
Learning is another significant cognitive process that involves the acquisition, synthesis, and integration of new information with prior knowledge. Learning happens in the context of past experiences and plays a crucial role in understanding, remembering, and applying new concepts.
In this video, we will explore these cognitive processes in detail and their implications for designing user-centric interfaces. By optimizing our understanding of cognition and its processes, we can develop interfaces that enhance user experiences, knowledge acquisition, and overall satisfaction.
