In psychology, an impression refers to the mental construct formed through the interaction of sensory input and cognitive frameworks, shaping our perception of people or situations. This concept, grounded in aspects such as appearance, nonverbal signals, familiarity, and behavior, connects immediate experience with previous knowledge.
Authors such as Wilkie Collins examined its duality—simultaneously vivid and ambiguous—while Vernon Lee emphasized its transient, emotionally charged quality. David Hume associated impressions with the genesis of passion and perception, underscoring their influence on thought. These diverse viewpoints illustrate how impressions function as essential components of opinion, merging the temporary with the lasting.
