Stimuli may be automatically evaluated in ways that affect behavior, an "automatic evaluation". In a study conducted by Chen and Bargh, subjects were faster to pull a lever toward themselves (an approach tendency) when a word had a positive valence than a negative valence, and were similarly faster to push the lever away (an avoidance tendency) when the word had a negative valence compared to a positive valence. The "sequential evaluative priming paradigm" refers to the related phenomenon of response times reducing when primed by stimuli with congruent valence. In an examination of the generality of the effects of this paradigm, Bargh, Chaiken, Govender and Pratto show that simply seeing or hearing mention of stimuli triggers automatically activated evaluations. This occurs even when the subject has not been asked to think about their evaluation of the stimulus beforehand. It was further shown that novel stimuli are automatically evaluated and produce the same effect as nonnovel stimuli: when positively valenced novel stimuli prime positively valenced targets, reaction time is faster.
