Explanation: always remember the number above is the atomic number
According to Weber's law, the size of a just noticeable difference or difference is a constant proportion of the size of the initial stimulus.
Explanation: Weber’s law is a principle that describes that for two stimuli to be perceived as different, the stimuli should differ by a minimum constant percentage and not by a constant amount.
For example: in a noisy room it is required to shout in order to be heard in contrast a whisper can be heard in quiet room. For us to be aware consciously 50% of the time the minimum stimulation required for any stimuli.
The absolute threshold for difference between the two stimuli of any individual may vary and depends on the strength of the signal apart from the experience, alertness, expectation and motivation.
The individual’s difference threshold also known as just noticeable difference is the difference between two stimuli half of the time that we can distinguish.
c. It never changes during the experiment.
Should be called the Manubrium!
Dr. Charles is using fMRI when she uses strong magnets to track changes in the brain's blood-oxygen levels.
Functional magnetic resonance imaging or (fMRI) is a techique used to measure brain activity by detecting changes associated with blood flow. When an area of the brain is in use, blood flow to that region will increase.
