2026-09-20 Common and distinctive neuro-cognitive dynamics between chunk decomposition and chunk composition: EEG evidence doi:10.57760/sciencedb.nb.0002k en ## OverviewThis repository contains raw and processed data, procedures, and materials for the manuscript:"The common and distinctive neuro-cognitive dynamics between chunk decomposition and chunk composition: EEG evidence"## Folder structure and files### /Data and Code：Contains all raw/processed datasets (behavioral & EEG) and the corresponding analysis scripts.#### 1. Behavioral Data-`Behavior_Raw Data_Composition task`：Raw behavioral data for the Composition task.-`Behavior_Raw Data_Decomposition task`：Raw behavioral data for the Decomposition task.-`Behavior_Processed data`：Processed dataset covering Reaction Time (RT), Accuracy (ACC), and subjective "Aha!" insight experience scores for all subjects#### 2. EEG Data-`ERP_Composition_Mean amplitudes`：Processed ERP data for the Composition task, averaged across 55 electrodes and segmented into three time windows: 200–300 ms, 300–500 ms, and 500–800 ms.-`ERP_Decomposition_Mean amplitudes`：Processed ERP data for the Decomposition task, averaged across 55 electrodes and segmented into three time windows: 200–300 ms, 300–500 ms, and 500–800 ms.#### 3. Analysis Code-`Behavior_code`：Scripts used for processing and analyzing the behavioral data.-`EEG_code`：Scripts used for EEG preprocessing and statistical analysis. ### /Materials and Procedures： Contains all experimental stimulus materials and the formal experimental programs.#### 1. Experimental Programs-`pojie_FJ.es2`: Program for the Decomposition task. Correct response key is F（also `pojie_JF.es2` where correct response key is J）.-`zuhe_FJ.es2`：Program for the Composition task. Correct response key is F（also `zuhe_JF.es2` where correct response key is J）.#### 2. Stimulus Materials（The following subfolders are present within each of the four program files listed above, containing the corresponding stimulus materials.）-`zdy`：Experimental instructions.-`train`：Practice trial materials.-`fillers1_l`：The incorrect-solution type materials for the loose condition.（also `fillers1_t` for the tight condition）-`fillers2`：The no-solution type materials.-`loose`：Materials for the loose condition.
