奖励相关的中脑边缘多巴胺被认为在指导动物行为方面起着重要作用，使动物倾向于潜在的有益环境刺激，远离不太可能获得积极结果的对象。这被认为部分是由于对知觉和注意过程的影响：多巴胺启动了一系列认知事件，导致与奖励相关的知觉特征的启动。我们已经提供了行为和电生理证据，证明这种机制引导人类视觉搜索，我们称之为奖励启动效应。我们还证明了这种效应存在很大的个体差异。在这里，我们表明，奖励启动的行为差异预测非常好的个性指数，捕捉到一个人的行为是由奖励结果驱动的程度。与奖励寻求个性的参与者被发现是那些谁分配视觉资源的奖励相关的视觉特征的对象。这些结果补充了一个快速发展的文献，证明奖励在注意力控制中起着至关重要的作用。他们还说明了人格特质对感知和选择性注意力等低级认知过程的显著影响。
Reward-related mesolimbic dopamine is thought to play an important role in guiding animal behaviour, biasing approach towards potentially beneficial environmental stimuli and away from objects unlikely to garner positive outcome. This is considered to result in part from an impact on perceptual and attentional processes: dopamine initiates a series of cognitive events that result in the priming of reward-associated perceptual features. We have provided behavioural and electrophysiological evidence that this mechanism guides human vision in search, an effect we refer to as reward priming. We have also demonstrated that there is substantial individual variability in this effect. Here we show that behavioural differences in reward priming are predicted remarkably well by a personality index that captures the degree to which a person's behaviour is driven by reward outcome. Participants with reward-seeking personalities are found to be those who allocate visual resources to objects characterized by reward-associated visual features. These results add to a rapidly developing literature demonstrating the crucial role reward plays in attentional control. They additionally illustrate the striking impact personality traits can have on low-level cognitive processes like perception and selective attention.
