Design Example: Application of Archimedes' Principle
0 Views •
2025
Archimedes' principle is fundamental in analyzing the buoyant force and stability of floating bodies. In this example, a wooden block with a rectangular section floats in seawater. Based on the block's dimensions, its specific gravity and the specific weight of seawater are used to find the volume of water displaced and the center of buoyancy. The volume of seawater displaced by the block is determined by first calculating the block's weight. This is done by multiplying the block's volume by...

Misattribution of Arousal and Cognitive Dissonance

Source: Peter Mende-Siedlecki & Jay Van Bavel—New York University A host of research in psychology suggests that feelings of psychological arousal may be relatively ambiguous, and under certain circumstances, can lead us to make inaccurate conclusions about our own mental states. Much of this work flows from seminal research conducted by Stanley Schacter and and Jerome Singer. If someone experiences arousal and does not have an obvious, appropriate explanation, they may attempt to explain...

Numerical Cognition: More or Less

Source: Laboratories of Nicholaus Noles and Judith Danovitch—University of Louisville One of the goals of the modern education system is to teach children mathematical literacy. They are taught to add, subtract, multiply, and divide, and this base knowledge is used to support learning about geometry, algebra, calculus, physics, and statistics. School-aged children usually acquire these skills in formal educational settings, but the foundation of mathematical understanding is developed much...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University As an Assistant Professor of Psychology and Cognitive Science at Johns Hopkins University, I teach Introduction to Cognitive Psychology. This large class primarily consists of freshman and sophomores majoring in related fields, like Psychology, Neuroscience, or Cognitive Science. One of the challenges I face in the classroom is teaching students to appreciate how data are obtained in the process of performing experiments.

An Introduction to Cognition
0 Views •
2023
Cognition encompasses mental processes such as memory, perception, decision-making reasoning and language. Cognitive scientists are using a combination of behavioral and neuropsychological techniques to investigate the underlying neural substrates of cognition. They are interested in understanding how information is perceived, processed and how does it affect the final execution of behaviors. With this knowledge, researchers hope to develop new treatments for individuals with cognitive...
FAQs
They reduce the amount of information users must hold, search, and interpret at once by organizing content clearly and presenting familiar interaction patterns. Supporting recognition rather than recall lets people respond to visible cues instead of remembering instructions. This matters in engineering systems, where lower mental workload can help users act more effectively under real-world conditions.
Timely feedback shows how a system has responded, while familiar patterns help users interpret what they see and decide what to do next. Together, they make system behavior easier to follow during interaction. In control panels, software, and equipment, these features support clearer decisions without requiring users to reconstruct the system’s behavior from memory.
Recognition allows users to identify relevant information or actions from what the interface presents, whereas recall requires them to retrieve instructions or procedures from memory. Favoring recognition addresses limitations in human memory and can make interaction more direct. The distinction is especially important when people must use engineered systems efficiently rather than pause to remember required actions.
A mismatch can increase the likelihood of user errors because the system demands more perception, memory, or decision-making than the interaction supports. Cognitive design principles help engineers anticipate these limitations and organize interaction accordingly. This concern extends across medical devices, vehicles, industrial equipment, and control panels, where errors can affect safety as well as usability.
Engineers can examine how users will perceive information, remember instructions, make decisions, and act, then organize the interface around those demands. They can use clear information structures, familiar patterns, timely feedback, and recognition-based support. Applying these considerations throughout product or system design helps address human limitations before mismatches produce interaction problems.
Software, control panels, medical devices, vehicles, and industrial equipment all provide contexts for applying cognitive design principles. These systems require people to interpret information and respond to system behavior, often under real-world conditions. Using the principles in each context helps engineers align interaction with human capabilities while supporting usability, safety, efficiency, accessibility, and user satisfaction.
They connect usability with broader engineering outcomes by addressing the causes of interaction difficulty rather than treating user problems as isolated mistakes. Clear organization, feedback, familiar patterns, and recognition-based support can improve safety and efficiency while also promoting accessibility and satisfaction. This makes cognitive considerations relevant to the overall performance of human-centered products and systems.
