[top]James-Lange Theory of Emotion

James-Lange Theory of Emotion was posed by both James and Lang at approximately the same time (hence the name James-Lange) and suggests emotions are a consequence of our physiological responses to external stimuli followed by identification of the emotion by examining the physical responses. So, some external stimulus produces a physiological response in your body. Then, you examine this physiological response and identify the emotion you are experiencing based on the physiological response. For example, you see a bear in the woods, and you begin to tremble. You then identify the fact that you are trembling and conclude that you are afraid..."I am trembling, therefore I am afraid."

[top]Just Noticeable Difference

The just noticeable difference (JND), also known as the difference threshold, is the minimum difference in stimulation that a person can detect 50 percent of the time. For example, let's say I asked you to put your hand out and in it I placed a pile of sand. Then, I add tiny amounts of sand to your hand and ask you to tell me when you notice any change in the overall weight. As soon as you can detect any change in the weight, that difference between the weight of the sand before I added that last bit of sand and the amount of sand after I added it, is the just noticeable difference.

[top]Just-World Phenomenon

The just-world phenomenon is the tendency for people to believe that the world is just and that people therefore get what they deserve and deserve what they get. If you have this belief, and something good happens to you, you may conclude that the world is just because you are a good person and so good things happen to you. In the same way, when you see something bad happen to someone else, you may conclude that they did something to bring on this bad event. Otherwise, it would not have occurred since the world is a just place.
