This is a basic auditory task designed to measure sound intensity that was adapted from Goswami et al. (2011). Subjects hear 2 stimuli and are asked to indicate which one was softer than the other. Stimuli difference begins at 13.8dB from standard stimulus and changes adaptively based on subject performance, to a maximum of 19.5 dB.
Total Items: Adaptive in 2 down, 1 up procedure
Completion Time: 8 minutes
Dependent Variable: Threshold of Stimuli Difference (dB)
This task is programmed in PsychoPy. Please contact me for task usage.
