My PhD project is called the “Radboud Early Academic Development Inquiry” (READI).
The READI project is a 5-wave longitudinal study, examining individual differences in early reading and math development throughout early primary school.
Across these five ‘waves’ (kindergarten – 2nd grade), we repeatedly assessed various cognitive, numeracy- and literacy-related abilities. Home-related measures such as parental education level (SES), parental expectations and parent-child activities were also included.
The project involved an initial sample of 224 children, and achieved a retention rate of 94% at the fifth time point.
Graphical description of the READI project:
Tasks that were included in our task battery:
Literacy:
- phonological skills
- vocabulary (Peabody)
- letter knowledge
- word reading fluency (DMT)
Numeracy:
- rote counting
- symbolic comparisons
- numberline estimation
- applied math
- arithmetic fluency (TTA)
‘General’ cognitive skills:
- verbal WM
- visuospatial WM
- non-verbal reasoning (Raven)
- rapid naming (RAN)
The data collection for the READI project was recently finished, in November 2024.
