Caption: : 5 SENSES

Sight: If you’re standing at a high point in total darkness, you can see a candle30 miles awaySound: If you’re in a very quiet room, you can hear a watch ticking 20 feet away.Smell: You can smell a drop of perfume in about 800 square feet of space.Touch: You can feel a human hair on your skin.Taste: You can taste a teaspoon of sugar in two gallons of water.

SIGNAL DETECTION THEORY:Detecting something is not necessarily simple. Your senses may perceive a stimulus, but that doesn’t mean that you’re paying attention to it.Sensitivity and bias:Imagine you are expecting a text or phone call. They have not called yet but you go and check on your phone multiple times to see if they have called you. In fact, sometimes the stimulus is there and you miss it, and sometimesit’s not there and you think you hear or see it. This is the signal detection theory according with Scientist.
