A neuroimaging dataset on orthographic, phonological and semantic word processing in school-aged children

Abstract

Here we describe the public neuroimaging and behavioral dataset entitled “Cross-Sectional Multidomain Lexical Processing” available on the OpenNeuro project ( https://openneuro.org). This dataset explores the neural mechanisms and development of lexical processing through task based functional magnetic resonance imaging (fMRI) of rhyming, spelling, and semantic judgement tasks in both the auditory and visual modalities. Each task employed varying degrees of trial difficulty, including conflicting versus non-conflicting orthography-phonology pairs (e.g. harm – warm, wall – tall) in the rhyming and spelling tasks as well as high versus low word pair association in the semantic tasks (e.g. dog – cat, dish – plate). In addition, this dataset contains scores from a battery of standardized psychoeducational assessments allowing for future analyses of brain-behavior relations. Data were collected from a cross-sectional sample of 91 typically developing children aged 8.7- to 15.5- years old. The cross-sectional design employed in this dataset as well as the inclusion of multiple measures of lexical processing in varying difficulties and modalities allows for multiple avenues of future research on reading development.
