Demetri is a participant in an auditory detection study using the method of constant stimuli. He never detects the 10 unit tone.
He detects the 20 unit tone 25% of the trials. He detects the 30 unit tone 50% of the trials. He detects the 40 unit tone 80% of the trials. He detects the 50 unit tone 95% of the trials. His threshold for hearing tones would be taken as the _________.
Based on the information provided within the question it can be said that his threshold for hearing tones would be taken as the 30 unit tone. This is because "threshold" refers to the amount that must be exceeded for a certain result to occur or manifest. Which in this case is indicated by the 50% mark that the 30 unit tone indicates. Making it the minimum for consistency.
