  5. Crazy Rules: Self-Organization and Chaos Theory Components of Human Language • Data Storage and retrieval in the brain (Neural Darwinism ⇒ Frequencies) • Acoustics • Semantics (from idiosyncratic to systematic: “twodogs”)

  6. Crazy Rules: Self-Organization and Chaos Theory The Bidirectional Table • Speakers are probabilistic learners, guided by: • Memory and Common Practice • Perceptual Reliability / Avoiding Semantic Biases • Large scale individual behaviour can be modelled with stochastic approximations  “Ideal Speaker”

  7. Crazy Rules: Self-Organization and Chaos Theory The working of the bidirectional table:Middle Frisian hab, habbe & habba

  8. Crazy Rules: Self-Organization and Chaos Theory Stability and Instability • If language is deterministic and developing towards equilibria: where do the changes come from? • Example: Old English: - 3 vowel system in unstressed syllables - Stable for 200 years, followed by change - Learning not based on unlimited dataset

  9. Crazy Rules: Self-Organization and Chaos Theory Balancing PowersGeneral phonetic centralization tendency 31% /e/ /u/ 28% [ə] 9% 10% Distributional proportions based on Old English text Noise levels based on modern vowel duration contrast 8% /a/ 41%

  11. Crazy Rules: Self-Organization and Chaos Theory /e/ and the equilibrium The equilibrium is only preserved in a narrow strip in the proportion – noise area! /e/ > /ə / equil. /a/ > /ə /

  12. Crazy Rules: Self-Organization and Chaos Theory /a/ and the equilibrium The threshold of /u/ > /ə/ shows CHAOTIC behaviour! /a/ > /ə / equil. /u/>/ə /

  13. Crazy Rules: Self-Organization and Chaos Theory Chance and resolution (I) • Large scale individual behaviour can be modelled with stochastic behaviour • Only true for sample size (n) ⇒ ∞ p = observed proportion for phenomenon x P = statistical chance for x to appear nx = number of observations with x nt = total number of observations nx/nt = p ≈ P

  14. Crazy Rules: Self-Organization and Chaos Theory Chance and resolution (II) • Throw a die 10 times • Chance for ‘6’ = 1/6 • 1/6 * 10 = 1,67 • ‘best match’ = 2 times ‘6’ • (2-1,67)/1,67 = 20% deviation

  16. Crazy Rules: Self-Organization and Chaos Theory Consequences for system stability /a/ > /ə / /a/ > /ə / equil. equil. /u/>/ə / /u/>/ə /

  17. Crazy Rules: Self-Organization and Chaos Theory Consequences for system stability • Smaller sample sets broaden the equilibrium zone: robust for chance variation. • Smaller sample sets increase unpredictable threshold behaviour: chaotic character. /a/ > /ə / equil. /u/>/ə /

  18. Crazy Rules: Self-Organization and Chaos Theory Conclusion • The Bidirectional Table models the interaction of memory (frequency), acoustics (noise levels) and semantics (functional contrasts) • It predicts and explains e.g.: • stability of sound or lexical contrasts • structural differences depending on population size • both equilibrium situations and chaotic disturbances
