Possible Dependent Variables

  • blood pressure (systolic, diastolic, changes in blood pressure)
  • conductivity (skin conductivity, perspiration, electrocardiogram patterns)
  • eyes (pupil constriction, dilation, rate of dilation, movement, blinking, stereoscopic vision)
  • fatigue (reduction in grip strength, grip frequency)
  • focus (depth of focus, eye dominance)
  • heart rate (rate, recovery rate)
  • memory (sequence, number, shape, concept, frequency, attenuation)
  • muscle strength (force, duration, speed)
  • perception (time, perspective, relationship, position)
  • reaction rate (eye movement, hand movement, verbal response)
  • reflex (knee jerk, eye blink, time of reflex, strength of reflex)
  • respiration (tidal volume, breathing rate)
  • smell (odor, discrimination, accommodation, recognition)
  • sound (volume, pitch, discrimination, attenuation, accommodation)
  • spatial (sense of up, down, relationship of objects, position)
  • stride (pace, length, rate)
  • taste (flavor, discrimination, accommodation, recognition, attenuation)
  • temperature (core temperature, surface temperature)
  • temperature sensation (heat, cold, discrimination, accommodation)
  • touch (pressure, location discrimination, attenuation, recognition)
  • vision (resolution, recognition, color, distinction, appearance, accommodation)
