  1. SZ schizophrenia group, HC healthy control group.
  2. aNovelty Exploration Task (NET) behavioural measures: Distance, total distance travelled (m); Spatial d, index of complexity of locomotion – lower values indicate more linear, less circumscribed movement; VisObjExp, visual object exploration (Count, number of objects explored; Time, duration (s) of exploration); TacObjExp, tactile object exploration (Count, number of objects explored; Time, duration (s) of exploration).
  3. bActivity Preference Task (APT) behavioural measures: Active Time, duration (s) on active engagement option; Switches, number of switches between active and passive engagement options; Active Intensity, average hand speed (m/s) during periods of active engagement; Active Persistence, index of tendency to sustain continuous active engagement.
  4. cNET-related measures.
  5. dAPT-related measures.
  6. eExploratory measures (administered to subsamples).
