This task is an auditory task designed to measure roving intensity perception and was also adapted from Goswami et al. (2011). Subjects hear 2 stimuli and are asked to indicate which had a softer rise. Stimulus onset difference (i.e. time it takes for stimulus to reach full intensity) begins at 278 ms and changes adaptively based on subject performance.
Total Items: Adaptive in 2 down, 1 up procedure
Completion Time: 8 minutes
Dependent Variable: Threshold of Stimuli Difference (ms)
This task is programmed in PsychoPy. Please contact me for task usage.
