Empirical Scoring System - Multinomial

Scoring Features

Expand AllCollapse All

• RESPIRATORY FEATURES

  • Decrease in respiration amplitude for three or more respiratory cycles, beginning after the stimulus onset
  • Slowing of respiration rate for three or more respiratory cycles, beginning after the stimulus onset
  • Temporary increase in respiratory baseline for three or more respiratory cycles, beginning after the stimulus onset

• EDA FEATURE

  • Electrodermal response amplitude

• CARDIO FEATURE

  • Increase in relative blood pressure (could be measured at baseline, mid, or systolic)

• FINGER PULSE AMPLITUDE FEATURE

  • Constriction (decrease) in the fingertip pulse amplitude

• SCORING

  Assign values of +, -, or 0 using the 3-position scale and the bigger-is-better rule

  • Score any difference in response magnitude
  • Use Primary Features only
  • For each component sensor, score each RQ against the comparison question that produced the greatest change in physiological activity
  • EDA should be scored as +2, -2, or 0

  Score only timely reactions

  • Do not score reactions that begin before the stimulus
  • Do not score reactions that begin more than 5 seconds after a timely answer

  Score only stable and non-artifacted data

  • Do not attempt to score data that are affected by movement artifacts
  • Do not attempt to score messy or unstable segments of data
  • Do not attempt to score data of unusual response quality (dampened or exaggerated)
    • e.g., abnormally slow or very fast breathing
