Featured: Human Perception
Human Perception deals with the way the mind perceives the stimuli around you. Learn how your senses function and help you recognize your environment.
- Can a person remember being born?
You may vaguely remember scratching your chicken pox at the age of 3, but do you remember the moment your body burst into the wide open world? Most likely not. - Can people feel the pain of others? Is there any truth behind the idea of sympathy pains? Mirror-touch synesthesia causes people to feel touches and pains that others experience.
- How Colorblindness Works Roses are red, violets are blue -- well, bluish. The sky is blue, too. Grass is green. These are things that most of us know for a fact and don't question. But what if you were colorblind? What would you see? Is life one long black-and-white movie?
- How Food Craving Works As you surf the Web, your mind is distracted by the thought of warm cookies floating in cold milk. Will this craving ever subside or do you need chocolaty satisfaction ASAP?
- How Smell Works Smell is a basic sense, but scientists are still exploring how it works. Why are researchers, developers and even government agencies so curious about smell? What makes a seemingly simple sense so tantalizing?
- How Taste Works Taste might seem like the simplest sense. But we know much less about taste than we do about sight and hearing. Why is taste so mysterious? And what on earth is umami?
- Why do loud noises cause your ears to ring? Back away from that speaker, turn down that iPod and put down that power tool unless you want the ringing in your ears to remain permanent. Sound can hurt you, and that ringing may be the first sign.
- How many senses does a human being have? We've all heard of a "sixth sense" and extra-sensory perception. So how many ways can we actually sense the world around us?
