Conclusion 887 changes in achievement imagery (i.e., hope for success imagery), affective arousal (i.e., tense arousal, energetic arousal, and hedonic tone), and performance (i.e., reaction time and error rate) on a mental concentration task. As predicted, the achievement vision increased hope for success imagery and tense arousal, and reduced reaction times and error rates.Furthermore, the strength of the person's pre-vision hope for success moderated the influence of achievement vision on energetic arousal and reaction time. Study 3 focused on the domains of affiliation and power, thereby contrasting two motive domains that are known to have opposite effects on the following motivation indicators: changes in salivary alphaamylase, affective arousal, and cooperation behavior in a prisoner's dilemma.As predicted, the affiliation vision promoted hedonic tone, especially in participants high in the need for affiliation, whereas the power vision promoted tense arousal and interacted with pre-vision need for power to increase energetic arousal. Moreover, the power vision increased the alphaamylase level and exploitative behavior, particularly in participants high in the need for power. In contrast, the affiliation vision increased cooperation behavior, especially in predominantly affiliation-motivated participants. In sum, the present research provides the first empirical evidence that visions are motivationally effective by arousing implicit motives.
