It is probably best to start with one very important distinction that can often be confusing: The physical process during which our sensory organs—those involved with hearing and taste, for example—respond to external stimuli is called sensation.

Sensation happens when you eat noodles or feel the wind on your face or hear a car horn honking in the distance.

During sensation, our sense organs are engaging in transductionthe conversion of one form of energy into another. Physical energy such as light or a sound wave is converted into a form of energy the brain can understand: After our brain receives the electrical signals, we make sense of all this stimulation and begin to appreciate the complex world around us.

This psychological process—making sense of the stimuli—is called perception. It is during this process that you are able to identify a gas leak in your home or a song that reminds you of a specific afternoon spent with friends.

Regardless of whether we are talking about sight or taste or any of the individual senses, there are a number of basic principles that influence the way our sense organs work. The first of these influences is our ability to detect an external stimulus. Each sense organ—our eyes or tongue, for instance—requires a minimal amount of stimulation in order to detect a stimulus.

The way we measure absolute thresholds is by using a method called signal detection. This process involves presenting stimuli of varying intensities to a research participant in order to determine the level at which he or she can reliably detect stimulation in a given sense.

During one type of hearing test, for example, a person listens to increasingly louder tones starting from silence in an effort to determine the threshold at which he or she begins to hear see Additional Resources for a video demonstration of a high-frequency ringtone that can only be heard by young people.

Correctly indicating that a sound was heard is called a hit; failing to do so is called a miss. Through these and other studies, we have been able to gain an understanding of just how remarkable our senses are. For example, the human eye is capable of detecting candlelight from 30 miles away in the dark.

We are also capable of hearing the ticking of a watch in a quiet environment from 20 feet away. A similar principle to the absolute threshold discussed above underlies our ability to detect the difference between two stimuli of different intensities.

The differential thresholdor just noticeable difference JNDfor each sense has been studied using similar methods to signal detection.Eyewitness memory is a person's episodic memory for a crime or other dramatic event that he or she has witnessed.

Eyewitness testimony is often relied upon in the judicial can also refer to an individual's memory for a face, where they are required to remember the face of their perpetrator, for example. However, the accuracy of eyewitness memories is sometimes questioned because.
