Abstract

fetched live from OpenAlex

One hypothesized component of speech production is “efference copy”; a signal carrying the predicted sensory-consequences of the motor-system’s actions [Wolpert and Ghahramani (2000)]. While brain-imaging studies [e.g., Aliu et al. (2009); Numminen et al. (1999)] have shown dampened auditory-cortex response to self-generated sounds (the predicted effect of efference copy), there are few behavioral demonstrations. This experiment will examine whether a context-effect (a common behavioral measure) is also dampened by efference copy. A context effect is a shift in categorization caused by surrounding sounds. For example, a syllable ambiguous between /da/ and /ga/ is perceived as more /da/-like when preceded by /ar/, but more /ga/-like when preceded by /al/ [Mann (1980)]. In this experiment, participants will silently mouth /ar/ or /al/ in time to a recording (it is assumed that mouthing engages efference copy). In one condition the recording will match what participants are mouthing; in another condition it will mismatch; in a third condition participants will hear the sounds without mouthing. After each mouthing, they will categorize a target syllable as /da/ or /ga/. The prediction is that the context effect will be dampened in the matching condition (due to efference copy), but not in the mismatching condition.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
