Lateralization of phonetic and pitch discrimination in speech processing

Zatorre, Robert J., Evans, Alan C., Meyer, Ernst, Gjedde, Albert·1992·Science

Abstract

Cerebral activation was measured with positron emission tomography in ten human volunteers. The primary auditory cortex showed increased activity in response to noise bursts, whereas acoustically matched speech syllables activated secondary auditory cortices bilaterally. Instructions to make judgments about different attributes of the same speech signal resulted in activation of specific lateralized neural systems. Discrimination of phonetic structure led to increased activity in part of Broca's area of the left hemisphere, suggesting a role for articulatory recoding in phonetic perception. Processing changes in pitch produced activation of the right prefrontal cortex, consistent with the importance of right-hemisphere mechanisms in pitch perception.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • When subjects engage in pitch processing tasks, right hemisphere activation is present, whereas phonetic processing tasks using the same stimuli produce left hemisphere activation.

    “Moreover, even when phonetic content is available while subjects are engaged in pitch processing tasks, right hemisphere activation, as opposed to the left hemisphere activation resulting from phonetic processing tasks using the same stimuli, is present (Blumstein and Cooper, 1974;Zatorre et al., 1992).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
