Final answer:
The concept of 'sensory extinction' is likely a misunderstanding; the correct term is 'sensory adaptation', which is the decreased sensitivity to an unchanging stimulus in the environment.
Step-by-step explanation:
Sensory extinction is not a commonly used term in psychology. Based on the context given in the question and the options provided, it seems to be a misunderstanding or a miscommunication. However, in psychology, there is a concept known as sensory adaptation, which refers to the decreased sensitivity to an unchanging stimulus. This means over time, if a sensory stimulus remains constant without change, our sensitivity to that stimulus diminishes, and we become less aware of its presence. For example, when you enter a room with a strong odor, initially it might be very noticeable, but after some time, you may no longer perceive the smell as your sensory receptors 'adapt' to the constant stimulus.
Option 'a' and 'b' mentioned in the reference pertain to other concepts in sensory processing: 'transduction' refers to the conversion of a sensory stimulus into a neural signal by a sensory receptor, while 'difference threshold' is the minimum amount of change required for a person to notice a difference between two stimuli.
