Directory structure

The project assumes the following file directory system:

• .Rproj.file

  • processed_data

  • raw_data

    • covariates
    • events
    • facescene_contrast
    • motion
    • timecourses

  • results

    • demographics
    • figures
    • RQ1
    • RQ2
    • RQ3

  • scripts

Raw data

Includes fMRI pipeline outputs (e.g., timecourse and contrast files), events, covariates and motion information.

Processed data

Includes fMRI metrics of interest per participant, generated by script (2) from "raw data" and relevant for scripts (3-5) below.

Scripts for data analysis

The repository consists of the following folder:

• scripts/ containing Rmarkdown/script files as following:

  • (1) FRIC_BaselineCharacteristics.Rmd: reports demographic and motion characteristics of final sample.
  • (2) FRIC_MRIvariables.Rmd: generates fMRI variables i.e., functional maturity measures, magnitude of responses to face and scene events, inter-region correlations (also referred to as functional connectivity) and lateralisation index of FFA at two statistical thresholds.
  • (3) FRIC_DevelopmentalChange.Rmd: characterises age-related changes in functional maturity, response magnitude to face/scene events and functional connectivity of FFA, MMPFC, STS and amygdala, as well as age-related changes in lateralisation index of FFA.
  • (4) FRIC_FunctionalMaturityFFA.Rmd: tests whether functional connectivity to/functional maturity of MMPFC, STS and amygdala correlates with functional maturity of FFA.
  • (5) FRIC_LateralisationIndexFFA.Rmd: This script tests if the FFA lateralisation index correlates with functional connectivity to or functional maturity of MMPFC, STS and amygdala.
