If a fabula exists in the reader’s mind, then coherence is not literary per se. Coherence is mnemonic. I haven't yet found anyone in the field of cognitive narratology looking at plots (and other storylines) from the standpoint of working memory and/or constructive remembering, but I hope to find someone who might want to help me build something more publishable from this humble blog project of mine. For now, here's a working thesis in three basic points. A bibliography is appended below.
(1) Constructing a fabula during reading involves “working memory” (Baddeley 1986, 2000; Baddeley & Hitch 1974) and reconstructing a fabula after reading involves “constructive remembering” (re-sequencing bits of information recalled from “long term memory”; Schacter 1996, 2013).
(2) For the fabula to be chronological, the story content must convey self-sequencing temporal implications (Friedman 1993); causality and probability convey such implications, with causal event sequences attaining mnemonic coherence more efficiently than probable event sequences (Kukkonen 2017; Shannon & Weaver 1949); frequent patterns of human behavior are “cognitively chunked” due to human expertise at observing one another (Ericsson 2013, 2014; Chase & Simon 1973; Miller 1956).
(3) The coherence of particular storylines therefore varies depending on the “informational redundancy” (i.e., predictive power) of their underlying content, and this overall relativity of coherence thereby suggests that “Plot” is not a singular category but the upper range on a spectrum of coherence, with (e.g.) historical chronicles near the opposite end, and (e.g.) life stories near the middle.
Two possible applications of this thesis could be (A) helpfully complicating Hayden White’s binary paradigm of chronicles versus emplotments, and (B) introducing cognitive memory research as a scientific basis for theorizing the nature and origins of all human storytelling, both fiction and non-fiction. In cognitive terms, selectivity can be merely attentional, and emplotment can be largely mnemonic compression. The distortion of remembered (or imagined) experience enables increased coherence, which is “rememberability”.
I've blogged over 30,000 words on this (so far) during my multiple series on Time in Memory. Eventually, I may have to pursue formal graduate studies to get this done properly, but my family and my budget are holding out hope that some kind professional will catch fire on this topic and agree to collaborate. If neither of those ever happens, at least it's here on my blog. Despise not small beginnings, nor the shoulders of
