Coherence Continuity and Cohesion Theoretical Foundations for Document Design

There is a Need for General Theoretical Principles Describing/Explaining Effective Design -- Those Which Demonstrate "Unity" and Enhance Comprehension and Usability. Theories of Cohesion From Linguistics and of Comprehension in Psychology Are Likely Sources of Such General Principles. Unfortunately, Linguistic Approaches to Discourse Unity Have Focused Exclusively on Semantic Elements Such As Synonymy or Anaphora, and Have Ignored Other Linguistic Elements Such As Syntactic Parallelism and Phonological Alliteration. They Have Also Overlooked the Non-Linguistic Elements -- Visual Factors Such As Typography or Color, and Auditory Components Such As Pitch or Duration. in Addition, Linguistic Approaches Have Met With Criticism Because They Have Failed to Explain the Relationship Between Semantic Cohesive Elements and Coherence. on the Other Hand, Psychological Approaches to Discourse Comprehension Have Considered the Impact of a Wider Range of Discourse Elements -- Typographical Cuing of K
