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)
