Motivational intensity : ウィキペディア英語版 | Motivational intensity Motivational intensity is defined as the strength of the tendency to either approach a positive situation or event or to move away from a negative situation or event.〔Harmon-Jones, E., Gable, P. A., & Price, T. F. (2013). Does negative affect always narrow and positive affect always broaden the mind? Considering the influence of motivational intensity on cognitive scope. Current Directions in Psychological Science, 22, 301-307. doi: 10.1177/0963721413481353〕 For more information, see the motivational intensity and cognitive scope subheading under Affect (psychology). == Separation of Motivational Intensity and Valence ==
In psychology, the term ''valence'' is used to describe stimuli, events, situations and emotional states that are intrinsically attractive (positively valenced) or intrinsically aversive (negatively valenced). The valence of a stimulus or event tells us whether we are likely to approach or avoid it. Valence, however provides no information about the strength of this tendency as it is either positive or negative. Instead, the strength of this association is quantified as the Motivational Intensity. By analogy, the valence of a stimulus or event is like the sign of a correlation coefficient and its motivational intensity is like the coefficient magnitude. It has been suggested that valence ratings in normative data sets such as the International Affective Picture System (IAPS) might be used as proxies for motivational intensity.〔 However, valence and motivational intensity do not always go hand in hand with one another. For example, viewing a positively valenced picture of a cute cat is associated with low motivational intensity because participants like it but are not intrinsically driven towards it. In contrast, viewing a positively valenced picture of a dessert is associated with high motivational intensity because participants want and desire it.〔Gable, P. A., & Harmon-Jones, E. (2008a). Approach-motivated positive affect reduces breadth of attention. Psychological Science, 19, 476–482. doi: 10.1111/j.1467-9280.2008.02112.x〕 Valence and motivational intensity can be at odds with one another with negatively valenced stimuli as well.〔
