Data saving is not built in

This task collects experimental data but does not save it automatically. If you deploy this task for your study, you must implement your own data persistence mechanism (e.g., server-side logging, database, or file export).

Description

As part of the CRAB (Computerized Reading-related Assessment Battery), the Vocabulary task assesses receptive lexical knowledge by requiring children to select the picture corresponding to a heard or read word from among visual alternatives. This digital-based task indexes vocabulary breadth at the receptive level, for which robust associations with reading comprehension have been reported in the developmental literature.
