¹Boundaries of bin categories are represented as absolute distance from the target of slider value (with a theoretical range 0–100) and corresponding acoustic parameter

²Although both log attack and decay were manipulated in the Envelope subtask, only the attack threshold is reported because this was the parameter of interest

³NA, item excluded due to more than 30% of participants not moving the slider

⁴ß = arithmetic mean deviation in ratio of four harmonics from their original whole number integers
