In loudness judgment (Class 1), the time-error was positive in shorter intrapair intervals, and its negativity increased as intervals became longer. A systematic time-error was not found in pitch judgment (Class 2). The negatively directed time-errors were obtained in lifted weights and circular surfaces judgment (Class 1). In visual length judgment (Class 1), negativity of the time-error diminished in shorter intra-pair intervals, and its negativity increased as intervals became longer. These results have verified Stevens's proposal on the time-error and the exceptional result of visual length was explained by the speciality in this sense-modality.
