Abstract

We assessed whether self-related automatic and others-related controlled processes are modulated by chronotype and time-of-day. Here, a shape-label matching task composed of three geometrical shapes arbitrarily associated with you, friend, and stranger was used. Twenty Morning-types, and twenty Evening-types performed the task at the optimal and non-optimal times of day (i.e., 8 AM, or 8:30 PM). Morning-types did not exhibit noticeable synchrony effects, thus proving the better adaptation of these participants to non-optimal moments of the day as compared to Evening-types. Contrary to our predictions regarding the absence of automatic-processing modulation and the presence of controlled-processing influences by time-of-day, we found an influence on self-related but not others-related processing only in Evening-type participants. Although brain structures are not directly tackled, we argue that such modulation may be due to the dependence of the activation of the ventromedial prefrontal cortex (VMPFC), an essential component of the self-attention network on circadian rhythms.

测试时型和时间对与自我相关的自动处理和与他人相关的受控处理的调节作用
我们评估了与自我相关的自动过程和与他人相关的受控过程是否会受到时型和时间的影响。在这里,我们使用了一个由三个几何形状组成的形状标签匹配任务,这三个形状分别与你、朋友和陌生人相关联。20 名晨间型和 20 名傍晚型分别在一天中的最佳和非最佳时间(即上午 8 点或晚上 8:30)完成了这项任务。与黄昏型相比,晨间型参与者并没有表现出明显的同步效应,这证明他们能更好地适应一天中的非最佳时刻。与我们的预测相反,我们发现只有黄昏型的参与者才会受到与自己相关而非与他人相关的处理过程的影响。虽然没有直接涉及大脑结构,但我们认为这种调节可能是由于自我注意网络的重要组成部分--腹内侧前额叶皮层(VMPFC)的激活依赖于昼夜节律。
