Fig 2. Phenomenological parameters as a function of ISS frequency, estimated from both datasets (ORIG, diamonds, and FREQ, circles).

(a,b) Amplitude (a) and Lag (b) parameters of the periodic (sinusoidal) component of the response. (c,d) Asymptote (c) and timescale (d) parameters of the monotonic drift of the baseline toward greater hypometria. Each point is a condition defined by type of adaptation and ISS frequency. Blue and red colors correspond to horizontal Two-way and Global adaptation, respectively. Error bars are SEM across participants. These four parameters are further compared to the values predicted by the solution to the generative models tested.
