One's past behavior influences their present behavior. The effects of such response history have often been tested using response inhibition tasks. Since previous studies have highlighted the effect of immediate action history formed directly before the subsequent response in a laboratory environment, we aimed to elucidate the longer-term effects of response history, using repetitive and habitual consumer behavior in daily life as the response history. We used event-related potentials recorded in a Go/No-go task to investigate brain activity related to inhibitory control, hypothesizing that stimuli with a high frequency of choice in everyday life would elicit stronger inhibition-related activity, that is, the No-go-N2 component. Participants were asked to evaluate the frequency of purchase and use of some products, such as food and drink or social networking services (SNS) in everyday situations. Images of each product were assigned as stimuli in the Go and No-go trials according to the frequency of choice. The results showed that frequently purchased No-go stimuli yielded a larger amplitude of the No-go-N2 component and a negative shift between 200 and 300ms after the presentation of No-go stimuli. The results suggest that frequently chosen products evoke stronger inhibition conflicts and require greater cognitive control to withhold a response. Our findings showed that repeated purchase behavior in daily life forms a response history and has a long-term influence on the inhibition of even simple approaching behaviors, such as button pressing.
一个人的过去行为会影响其当前行为。这种反应历史的影响通常使用反应抑制任务来进行测试。由于先前的研究强调了在实验室环境中紧接后续反应之前直接形成的即时行动历史的影响，我们旨在以日常生活中的重复性和习惯性消费行为作为反应历史，来阐明反应历史的长期影响。我们使用在Go/No-go任务中记录的事件相关电位来研究与抑制控制相关的大脑活动，假设在日常生活中高频率被选择的刺激会引发更强的与抑制相关的活动，即No-go-N2成分。参与者被要求评估在日常情境中某些产品（如食品饮料或社交网络服务（SNS））的购买和使用频率。根据选择频率，将每种产品的图片作为Go和No-go试验中的刺激呈现。结果表明，频繁购买的No-go刺激在呈现No-go刺激后200至300毫秒之间产生了更大幅度的No-go-N2成分和负向偏移。结果表明，频繁被选择的产品会引发更强的抑制冲突，并且需要更大的认知控制来抑制反应。我们的研究结果表明，日常生活中的重复购买行为形成了一种反应历史，并且对即使是简单的接近行为（如按键）的抑制也有长期影响。
