Abstract

The aim of this study was to further elucidate the mechanisms of early and automatic object processing using a masked picture priming paradigm with both identity and exemplar repetition in functional MRI (fMRI). Masked repetition priming has been commonly used with words to isolate automatic, rapidly occurring mechanisms involved in visual word recognition; however, studies using the technique of masked priming with rapid presentation of pictures have been limited. This study demonstrates how the masked priming technique can be used to study early, automatic processing of rapidly presented complex objects. Temporal-occipital regions previously found to be sensitive to repetition priming in both masked word and unmasked picture studies were found to show repetition suppression for the identity primes only. Most notably, when divided into anterior and posterior divisions, the fusiform gyrus showed anatomically specific repetition suppression only in the posterior portion. This finding is comparable to that found in a previous study of masked word priming, and the similarity may suggest an overlap in the early identification processes for visual word form and visual object processing in this region. Finally, masked repetition of different exemplar objects did not result in reliable neural effects, suggesting that the underlying mechanisms of the more semantic-based, different exemplar priming may occur later or require the intervention of conscious processes.

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?

  • There is remarkable similarity in the response to visual form processing of letters, words and objects in the left ventral occipitotemporal cortex.

    “Several studies also replicated prior observations that there was remarkable similarity in the response to visual form processing of letters, words and objects (Eddy et al., 2007; Wright et al., 2008; Turkeltaub et al., 2008; Burgund et al., 2009; Kherif et al., 2011; Shinkareva et al., 2011).”

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.
