Winkielman, Ziembowicz & Nowak (2015), “The coherent and fluent mind”, Frontiers in Psychology 6:83, LIT-190, read in full in NOTE-146. None of the cited empirical studies, Ziembowicz et al. (2013) included, was read; their findings are as the article states them.
What was actually shown
The proposal (pp. 1–3). The standard account puts cross-modal unity in the integration of specific features at perceptual or decisional stages (McGurk, double flash, bouba/kiki). The article adds a route through processing dynamics: signals of processing quality from different modalities combine into one global, “free-floating” feeling of how well processing is going, and that feeling is then interpreted for its source and relevance. “The creation of a unified consciousness is facilitated by an experiential mechanism that combines signals of processing quality” (p. 3).
The evidence it reports (p. 2). In Ziembowicz et al. (2013), across three experiments, participants judged targets in one modality while exposed to regular or irregular backgrounds in another: tone-grammar melodies with visual figures, or the reverse. The kinds of regularity were unrelated (a tone-sequence grammar against 3-D realisability). Coherent backgrounds raised judgments of “regular” (Experiment 1), “familiar” (Experiment 2) and “possible” (Experiment 3), whatever the judgment type or target modality. No effect sizes are given.
Why a feeling. In other paradigms, participants report changed ease, effort or familiarity in “many (though not all)” experiments, fluency has physiological markers of positivity, and discounting removes the effect: telling participants that background music affects their “sense of familiarity” reduced false recognition across formats (Fazendeiro et al. 2005). Fluency and familiarity can be amodal and summed across sources (Curran & Dien 2003; Miller et al. 2008).
What could have come out otherwise. Unrelated coherence in one modality could have left judgments about the other untouched. As reported, it did not.
What this does not say
- That the transfer runs through experience. The authors say direct evidence is needed that the cross-modal effects involve changed subjective experience and that the integration is causal (p. 2). The support for the experiential route comes by analogy from other paradigms (NOTE-146, C3).
- That the feeling is always the one posited. Under hidden semantic coherence, participants “cannot report and re-attribute changing levels of fluency” and are “only aware of affective (hedonic) consequences” (Topolinski & Strack 2009, p. 2).
- That unity was measured. No study cited measures unity of experience. The step from “processing-quality feelings pool across modalities” to “this facilitates unified consciousness” is the conclusion, not a result (NOTE-146, C6).
- That a network model explains the data. The Hopfield-type network with a feedback loop on an order parameter (Lewenstein & Nowak 1989), and Drogosz & Nowak’s mere-exposure simulations with it, are an analogy; no model of the cross-modal data is presented.
- That this is integrated information. The integration meant is a psychological blending of felt quality, not IIT’s Φ (THEORY-523).
Connections
- Unity. THEORY-063 (Metzinger) puts the unity of experience in the integration of one global world-model into a single functional cluster. This account offers a candidate psychological contributor to felt unity at another level; neither engages the other, and both could be true. Kleiner & Ludwig (THEORY-498) take the subsumptive unity thesis as a premise and derive a structure from it, not a mechanism.
- Global signals. The pooled feeling is a scalar monitor, not a broadcast of content, so it is a different kind of global variable from the workspace of THEORY-096. Treating it as an indicator of consciousness in AI (LIT-056) would be the reader’s extrapolation.
