Interpersonal & Mediated Communication

← Back to Domain-Specific Families

Abstractions about expressive and receptive language, nonverbal exchange, social presence, media richness, context collapse, and communication across channels.

14 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Antithesis — Sharpen a contrast by fusing two primitives — parallel grammatical form and opposed content — so a matched syntactic frame delivers the opposition at a controlled, audible beat.
• Augmentative and Alternative Communication (AAC) — Support or replace failing speech not by handing over a device but by running a clinical pathway — assess residual capability across four channels, match a modality to it, design a core vocabulary, train the communication partners, and migrate the system as the condition changes.
• Channel Richness — The cue-carrying capacity of a communication medium, determined by the varieties of cues, feedback, linguistic flexibility, and personalization it can support.
• Context Collapse — The communication condition in which multiple audiences with irreconcilable norms are co-present in one channel, so a single utterance cannot satisfy all at once — a structural failure of the channel, not the speaker's judgment.
• Expressive Language — The clinical category for the output side of language — selecting, assembling, retrieving, and producing a decodable message — held apart from receptive comprehension because the two channels dissociate, and the discrepancy between them, not a composite score, drives intervention.
• Focus group — Convene six to ten people under a moderator to discuss a topic so that the interaction itself — the counters, reframings, and drawn-out silent voices — excavates collective meanings no individual held as a formed belief.
• Interpersonal Communication — Study meaning as co-constructed turn by turn in dyadic exchange, reading every utterance on two simultaneous layers — content and relational — and tracking a small running state (common ground, face, repair) whose updates give the trajectory.
• Media Richness Theory — Match a task's ambiguity to a medium whose cue capacity, feedback immediacy, language variety, and personal focus are sufficiently rich, diagnosing under- and over-richness as channel–task mismatch.
• Media Synchronicity — Match a communication medium to a task by decomposing the medium into five capabilities and reducing the task to one bit — convergence (build shared meaning fast and jointly) versus conveyance (transmit information the receiver processes at their own pace) — so higher synchronicity is not always better.
• Nonverbal Communication — Analyze face-to-face interaction as a finite set of meaning-bearing channels beyond words — kinesics, proxemics, haptics, chronemics, oculesics, vocalics, appearance — reading affect off the harder-to-fake channels when they diverge from speech.
• Receptive Language — The comprehension arm of language capacity — receiving, parsing, and interpreting incoming linguistic input — defined in contrastive opposition to expressive (production) language, dissociable from it, and assessed on its own through an ordered processing stack with output held near zero.
• Receptive–Expressive Language Profile — Assess language as two dissociable directional capacities — comprehension and production — and compare their separately measured levels, because the pattern of the gap localizes impairment and determines whether intervention targets input, output, or both.
• Social Communication — Treat the relational-pragmatic layer of language — turn-taking, relevance, politeness, repair, register, common ground — as a layer distinct from grammatical correctness that can fail on its own, so a child with clean syntax may still be unable to hold a conversation.
• Social Presence — The felt sense of being together with another social actor through a medium — a variable distinct from transmission fidelity, jointly produced by cue inventory, self-disclosure, turn-taking synchrony, and individual recognition, and upstream of engagement, trust, learning, and retention.
