From: Effect of lateral perturbations on psychophysical acceleration detection thresholds

Figure 1

A- D: Geometric Mean and Standard Deviations for lateral acceleration detection thresholds versus Displacement for three groups. Bold lines indicate mean, while thin lines above and below represent the mean +/- 1 geometric standard deviation A: Young adult averages and standard deviations B: Healthy older adults averages and standard deviations C: Diabetic older adults averages and standard deviations. D: Modeled negative power law relationships for healthy young adults (solid line), healthy older adults (long dashed line) and diabetic older adults (short dashed line). Only the linear portion of each curve before the critical point was modeled. Thresholds for displacements after the critical point were the same in all subjects in all groups (~10 mm/s2). E-H: Geometric Mean and Standard Deviation for Movement time versus deisplacement. E: Young adult F: Healthy older adults G: Diabetic older adults. H: Modeled negative power law relationships for healthy young adults (solid line), healthy older adults (long dashed line) and diabetic older adults (short dashed line). Only the linear portion of each curve before the critical point was modeled.
