The datasets include sensorimotor cortex activity measured by EEG, facial muscle responses measured by EMG, and observable facial movements at pre‑ and post‑test. All files share a common participant identifier, enabling merging across files. facial mimicry EMG EEG sensorimotor experience associative learning H1 Q1 dep_psy Richmond Chloe chloerichmond92@gmail.com Centre for Brain Science, Department of Psychology, University of Essex, Colchester, UK Parrett Lucy lucyparrett@sky.com Centre for Brain Science, Department of Psychology, University of Essex, Colchester, UK Tye Elizabeth et21422@essex.ac.uk Centre for Brain Science, Department of Psychology, University of Essex, Colchester, UK de Klerk Carina C.J.M. c.deklerk@essex.ac.uk Centre for Brain Science, Department of Psychology, University of Essex, Colchester, UK https://orcid.org/0000-0002-6005-7880 Numeric 2022-07-20 2023-12-18 2022-07-20 2023-12-18 Wider Colchester area, UK EEG, EMG, and behavioural coding were used to create these datasets.
