Social cognition
Understanding how we take in, process, and act on cues from other people is central to communication research. At first glance, “social cognition” and “social perception” look like synonyms—but they refer to related yet distinct slices of that process. Social perception is the front-end: the sensory and interpretive work we do to notice and decode facial expressions, tone of voice, eye gaze and other social signals. Social cognition is the whole pipeline: perception plus the memory, attribution, stereotyping, schema activation, judgment and decision-making steps that follow. You can’t have social cognition without social perception, but you can perceive without engaging the full cognitive machinery. Recognizing that difference helps communication scholars predict when misreads will occur, design better message strategies, and build richer theories of interpersonal understanding.

The two processes operate in an interactive loop: what we perceive shapes our cognitions, and our existing cognitions tune what we perceive (confirmation bias, selective attention). (,

3. Why the distinction matters in communication theory
Impression formation & person perception
At the perception stage, receivers attend to style (dress, accent, non-verbals) before content; mismatches create noise and reduce source credibility. (, )
Message design & adaptation
Models such as social-cognitive approaches to interpersonal communication argue that speakers continually build mental models of partners (“audience design”)—a cognition step—based on the cues they perceive. ()
Attribution & relational dynamics
Attribution theories (a branch of social cognition) explain why identical behaviors are forgiven in friends yet condemned in strangers: different stored schemas and inferential rules. (, )
Mediated interaction
Computer-mediated communication strips out many perceptual cues, forcing users to rely more on cognitive reconstruction (e.g., Social Information Processing Theory). (
)Training & interventions
Skills-training programs that teach children or clinical populations to recognize emotions (perception) often progress to modules on planning effective responses (cognition). (

5. Take-aways for scholars and practitioners
By distinguishing the snapshot work of social perception from the full story work of social cognition, communication theorists gain sharper tools for explaining how meaning is made—and unmade—in every human exchange.
