Processing fluency

In cognitive psychology, processing fluency is the ease with which information is processed by the brain. It is commonly treated as a synonym for cognitive fluency, a term used to describe the subjective experience of ease or difficulty associated with mental tasks. Processing fluency influences a range of judgments and decisions, including perceptions of truth, attractiveness, familiarity, and confidence.

Several subtypes of processing fluency have been identified. Perceptual fluency refers to the ease of processing sensory stimuli, which can be affected by factors such as visual clarity, contrast, or exposure duration. Retrieval fluency involves the ease with which information is accessed from memory.

Higher fluency is often associated with more favorable evaluations, even when the ease of processing is unrelated to the content itself, a cognitive bias known as the fluency heuristic.
