What is mental imagery?

Mental imagery is defined as the ability to visualize sensory experiences without the presence of external stimuli. This means that individuals can form mental pictures or representations in their mind based on past experiences, thoughts, or imagination without needing to see, hear, or otherwise sense those stimuli in real-time. For example, when you think of your favorite place, you can conjure up an image of it in your mind, complete with colors, shapes, and maybe even sounds, despite not actually being there.

This ability can be applied across various cognitive tasks, such as problem-solving, memory recall, and even in the creative process. Mental imagery is important in many psychological functions, including enhancing memory and supporting complex cognitive tasks, allowing individuals to simulate experiences or contemplate scenarios without direct external input.
