1 INTRODUCTION Humans typically explore and gather haptic information using discriminative touch through the glabrous skin on their hands and digits (Gibson, 1962; Lederman & Klatzky, 1993; Wagner & Gibson, 2016). Previous research investigating texture perception and brain activation commonly focus on one textural feature, with roughness the most studied (Hollins et al., 2000).

Analysis Event-related time–frequency analysis was conducted using synchronised EEG and touch sensor data. Movement onset timings, computed on a trial-by-trial basis relative to the trial-onset visual cue, were synchronised to EEG data. EEG data were epoched −5.5–5 s relative to the movement onset marker. Data were imported into the SPM12 software package (Statistical Parametric Mapping, University College London, England) in MATLAB (The MathWorks, Inc., USA).
