What are cones especially sensitive to?
S Cones are most sensitive to light at wavelengths around 420 nm. However, the lens and cornea of the human eye are increasingly absorptive to shorter wavelengths, and this sets the short wavelength limit of human-visible light to approximately 380 nm, which is therefore called ‘ultraviolet’ light.
Which of the following is an example of sensory adaptation?
Examples of sensory adaptation include light and dark adaptation, hearing, smell, touch and eye-hand coordination. Sensory adaptation occurs when the sensory adaptation in animals changes based on their sensitivity to stimulus.
Can a wrist watch sense and respond to stimuli?
Yes, wristwatch wearers are more emotionally stable and can keep their cool better than those who do not wear one. The reason is explained through an experiment to check how both sides respond to different stimuli. But the ones with wristwatches remained calm and collected to a certain level.
What are the disadvantages of adapting to a stimulus?
The effects of adaptation can be observed for all senses. For the chemical senses, the effect is that a constant odor or taste stimulus will be perceived as decreasing in intensity while sensitivity to that stimulus is also decreased. For sensory evaluation, this poses problems.

What is the difference between sensation and perception?
Sensation and perception are two separate processes that are very closely related. Sensation is input about the physical world obtained by our sensory receptors, and perception is the process by which the brain selects, organizes, and interprets these sensations.
