Psychological processes refer to the mental activities that influence how we think, feel, and behave. These processes include perception, memory, reasoning, and decision-making. They help us interpret our experiences and respond to our environment, shaping our understanding of the world around us. These processes are essential for learning and adapting to new situations. For example, memory allows us to retain information, while perception helps us make sense of sensory input. Understanding these processes is crucial in fields like psychology and cognitive science, as they provide insights into human behavior and mental functioning.
