Thresholds measured in the no-precursor condition in two tasks in terms of target-to-masker ratio (TMR) for individual listeners. The level of 0 dB TMR is equivalent to a target level of 45 dB SPL, the same level as the masker components. Each ellipse represents the data from one participant. The coordinates of each ellipse center are the mean thresholds in the two tasks and the height and width of each ellipse represent the standard deviations across the last four runs for each participant for each task. Black solid ellipses represent participants who started with the Present/Absent task and then completed the Up/Down task, whereas the grey dashed ellipses represent participants who completed the two tasks in the opposite order.
