Cognitive ease refers to the mental state where our brain processes information quickly and effortlessly. When we encounter familiar concepts or simple language, we experience cognitive ease, making it easier to understand and accept ideas. This state often leads to positive feelings and a sense of comfort. In contrast, cognitive strain occurs when we face complex or unfamiliar information, requiring more mental effort. This can lead to confusion or skepticism. Factors like font readability, color contrast, and familiarity with a topic can influence cognitive ease, affecting how we perceive and respond to information.
