Gottman, J. M., & Silver, N. (1999). The Seven Principles for Making Marriage Work. Crown. — the actual source of 'discussions invariably end on the same note they begin', the 96%/first-three-minutes claim, the four-horsemen order, contempt as 'the worst of the four horsemen', the 82% four-horsemen figure and the 84% repair-attempt figure. Currently the module cites only the 1994 book, so the work it actually draws on is uncited.
Carrère, S., & Gottman, J. M. (1999). Predicting divorce among newlyweds from the first three minutes of a marital conflict discussion. Family Process, 38(3), 293-301. — the peer-reviewed study behind section 16, as opposed to the trade-book retelling.
Heyman, R. E., & Slep, A. M. S. (2001). The hazards of predicting divorce without crossvalidation. Journal of Marriage and Family, 63(2), 473-479. — required alongside any Gottman accuracy figure; the models were fitted on couples whose outcomes were already known.
Lieberman, M. D., Eisenberger, N. I., Crockett, M. J., Tom, S. M., Pfeifer, J. H., & Way, B. M. (2007). Putting feelings into words: Affect labeling disrupts amygdala activity in response to affective stimuli. Psychological Science, 18(5), 421-428. — the measurement behind 'naming the feeling takes some heat out of it', which sections 25-27 currently credit only to two popular business books.
Rogers, C. R. (1952). Communication: Its Blocking and Its Facilitation. Northwestern University Information (address delivered 1951); reprinted in On Becoming a Person (1961). — provenance for the section 24 quote, currently attributed only to 'Carl Rogers'.
