Question

Daniel wants to find out if he can notice the difference in light intensity when he adds some lit candles to a set of lit candles. when he adds 24 candles to his set, he notices the difference in intensity half the time. when he adds 11 candles to his set, he notices the difference a quarter of the time. in this scenario, daniel's absolute threshold for detecting the change in light intensity is at _____ candles.

Answer 1

Answer:

24

Explanation:

Absolute threshold is a concept that refers to the most minimum level of a sensory stimulus that an individual can sense. Testing this usually require individuals to differentiate the intensity of a stimulus.

A general rule of thumb is that when an individual can sense whether something is stronger 50% of the time, that stimulus level is the person’s absolute threshold.

Thus, in the example of Daniel, we should only pay attention to his 24 candles experiment – since he can recognize the difference in light intensity, 50% of the time, when there are only 24 candles. When he added 11 more candles, making them 35 candles, his ability to recognize the light intensity differences are reduced to 25%.
