The way a room is lit can affect the way you make decisions | The brain and illusions | Scoop.it
The next time you want to turn down the emotional intensity before making an important decision, you may want to dim the lights first. A new study shows that human emotion, whether positive or negative, is felt more intensely under bright light. under bright lights emotions are felt more intensely. In the brighter room participants wanted spicier chicken wing sauce, thought the fictional character was more aggressive, found the women more attractive, felt better about positive words and worse about negative words, and drank more of the "favorable" juice and less of the "unfavorable" juice.
Gerald Carey's insight:

How bright lights MIGHT affect our emotions.

Suara Hati: Ilusi

Suara Hati: Ilusi | The brain and illusions | Scoop.it

Our visual system is designed to allow us functioning in three-dimensional environment which is filled with light, shading, color, texture, and full of objects of different sizes at different distances. Most of us take vision for granted without realizing how complex and difficult task our brain is performing in order to correctly represent the "real outside world". Our perception is created by our brain's interpretation of visual information and sometimes it results in fascinating visual illusions. Our mind gets "actively" involved in interpreting the perceptual input rather than passively recording the input. It does not always accurately represent that input.
