This dataset accompanies the paper “Motor Control Processes Moderate 
Working Memory Gating,” published in The Journal of Neuroscience. It contains 
the raw EEG recordings (not preprocessed) from the study, as well as each participant’s 
behavioral data within the EEG dataset struct (labeled as EEG.behaviordata). 
Mean age of subjects is 23.7 (sd=2.9). For any of your inquiries,

Participants' subject numbers were randomized to ensure anonymity and do not reflect 
the order of data collection. The dataset includes 32 participants in total. Two 
participants were excluded from all analyses due to misunderstanding of the 
task rules (one participant didn't follow the interference task, an the other participant
tried to use the response knobs during the target presentation). One participant was included
only in the behavioral analysis because of abnormal EEG data, and one participant was excluded 
based on predefined exclusion criteria. However these excluded participants are shared within 
this dataset to further ensure transparency. All cases are documented in the relevant notes and 
the participant info list "participants.tsv". 
 
For detailed methodological information, please refer to the paper or the 
associated OSF project (https://osf.io/7fve8). A brief summary of the 
experimental procedure is provided here. 
 
The experiment used a 2×2 within-subject design with four conditions: 
same-hand motor interference, different-hand motor interference, same-hand 
visuomotor interference, and different-hand visuomotor interference. 
Participants also completed 240 baseline trials with no interference. The 
experiment included 10 blocks, each containing 120 trials. 
 
Each trial began with a colored square or diamond presented for 500 ms. After 
a 2900 ms delay, participants reported the target color using a color wheel 
controlled by the left or right knob. The shape of the stimulus indicated 
which hand to use, and this mapping was counterbalanced across participants. 
Participants had 4000 ms to respond, and each trial ended with an inter-trial 
interval between 800 and 1400 ms. 
 
In two-thirds of the trials, an interference task occurred during the delay. 
At 900 ms, a left- or right-pointing triangle appeared, and participants 
pressed the knob with the corresponding hand. In the motor interference 
condition, these triangles were gray. In the visuomotor interference 
condition, the triangles were colored, with their hue shifted 60–90 degrees 
from the target color, introducing visual interference. In the remaining 
no-interference trials, a gray up- or down-pointing triangle appeared, and 
participants made no response until the color wheel appeared.
