Which of the following is true?
A) The absolute threshold for any stimulus is a constant.
B) The absolute threshold for any stimulus varies somewhat.
C) The absolute threshold is defined as the minimum amount of stimulation necessary for a stimulus to be detected 75 percent of the time.
D) The absolute threshold is defined as the minimum amount of stimulation necessary for a stimulus to be detected 60 percent of the time.
Absolute Threshold
The minimum intensity of a stimulus that one can detect 50% of the time, which varies across different sensory modalities.
Statistical Average
A value that signifies the central or typical value in a set of data, calculated by dividing the sum of all values by the number of values.
Stimulation Necessary
The requirement for physical or mental stimulation to facilitate learning, development, or achieving a heightened state of activity.

Final Answer :
B
Explanation :
The absolute threshold for any stimulus varies somewhat depending on factors such as background noise, individual differences, and the criteria for detection (e.g. detecting a faint light in a dark room versus in a well-lit room). While there is no exact percentage for detecting a stimulus, it is typically defined as the minimum amount of stimulation necessary for a stimulus to be detected at least 50% of the time. Therefore, options C and D are incorrect. Option A is also incorrect as it implies that the absolute threshold is always the same regardless of context or individual differences.
