Semantic context and visual feature effects in object naming: an fMRI study using arterial spin labeling

Hocking, Julia, McMahon, Katie L., de Zubicaray, Greig I.·2009·Journal of Cognitive Neuroscience

Abstract

Previous behavioral studies reported a robust effect of increased naming latencies when objects to be named were blocked within semantic category, compared to items blocked between category. This semantic context effect has been attributed to various mechanisms including inhibition or excitation of lexico-semantic representations and incremental learning of associations between semantic features and names, and is hypothesized to increase demands on verbal self-monitoring during speech production. Objects within categories also share many visual structural features, introducing a potential confound when interpreting the level at which the context effect might occur. Consistent with previous findings, we report a significant increase in response latencies when naming categorically related objects within blocks, an effect associated with increased perfusion fMRI signal bilaterally in the hippocampus and in the left middle to posterior superior temporal cortex. No perfusion changes were observed in the middle section of the left middle temporal cortex, a region associated with retrieval of lexical-semantic information in previous object naming studies. Although a manipulation of visual feature similarity did not influence naming latencies, we observed perfusion increases in the perirhinal cortex for naming objects with similar visual features that interacted with the semantic context in which objects were named. These results provide support for the view that the semantic context effect in object naming occurs due to an incremental learning mechanism, and involves increased demands on verbal self-monitoring.

  • Increased temporoparietal activation during challenging word retrieval tasks may simply be a consequence of increased verbal self-monitoring.

    “As the same temporoparietal area was activated when the post-articulatory auditory feedback was altered to create a conflict between the expected auditory response to the spoken name and the actual auditory response (Zheng et al., 2010), the increased temporoparietal activation during challenging word retrieval tasks may simply be a consequence of increased verbal self-monitoring (Hocking et al.,”
  • In left posterior planum temporale/temporoparietal area, activation increases when speech production is more error prone due to interference or speaking in a second language.

    “First, in the left posterior planum temporale/temporoparietal area that previous studies had associated with the silent imagination of heard speech, activation was found to increase when speech production was more error prone due to interference or speaking in a second language (Hocking et al., 2009; Abel et al., 2009; Simmonds et al., 2011; Parker Jones et al., 2012).”

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.
