Data and analysis code for "Implicit and Combined Implicit–Explicit Intervention for Spanish Regular Past Tense in Children With Developmental Language Disorder: An Exploratory Multiple-Baseline Study"

This record contains the de-identified session-level dataset and the R analysis code supporting the study “Implicit and Combined Implicit–Explicit Intervention for Spanish Regular Past Tense in Children With Developmental Language Disorder: An Exploratory Multiple-Baseline Study.” The dataset contains one row per participant and measurement session. It includes participant identifier, intervention condition, study phase, session number, and raw correct-response counts and denominators for trained and untrained regular preterite verbs. The R script reproduces descriptive summaries by participant, intervention condition, phase, and verb type; participant-level Tau-U estimates without baseline-trend correction; design-comparable between-case standardised mean differences (BC-SMDs) with first-order autoregressive [AR(1)] residual structures; independent-error (IID) sensitivity analyses; and the individual-trajectory figure. Maintenance observations are included in the descriptive summaries and the individual-trajectory figure but are excluded from Tau-U and BC-SMD estimation. The script requires an Excel workbook containing a worksheet named “Session_Level_Data.” This session-level dataset is distinct from the dataset previously deposited in Zenodo record 17927898 and should not be interpreted as a new version of that record. The dataset and documentation are released under the Creative Commons Attribution 4.0 International Licence. The R analysis code is released under the MIT Licence.
