"It's essentially impossible to present an olfactory stimulus that doesn't have an emotional valence to it."

The project fostered the development of several sentiment-mining software programs capable of retrieving the emotional valence and arousal in text produced by web users.

Lack of awareness: patient might have distorted recollection of past events with significant emotional valence.

An experiment examining how these factors combine to create aesthetic appreciation included experts and nonexperts rating their emotional valence, arousal, liking, and comprehension of abstract, modern, and classical art works.

However, emotional valence was highest for classical and modern art, while arousal was highest for abstract works.

Initially, the Fading Affect Bias was widely accepted as the process whereby the emotional valence of certain events fades over time.

It has been found that although negative and positive items are remembered or known to same the extent, the processes involved in remembering and knowing differs with emotional valence.

In some patients, the emotional response is exaggerated in intensity but is provoked by a stimulus with an emotional valence congruent with the character of the emotional display.

Affective forecasting can be divided into four components: predictions about emotional valence (i.e. positive or negative), the specific emotions experienced, their duration, and their intensity.

The studies that did investigate this dimension have found that emotional valence alone can enhance memory, that is, nonarousing items with positive or negative valence can be better remembered than neutral items.
