时间期待是指个体利用环境中的时间信息预测目标刺激何时出现的能力。相关的认知模型可以分为两类：一类侧重于解释时间期待的形成过程,如痕迹条件反射模型、双加工模型、动态注意模型、时间定向理论等;另一类侧重于解释时间期待的更新过程,如策略模型和时间再定位模型等。不同类型的时间期待激活的脑区不同,表明时间期待的产生和更新过程存在分离：期待的产生激活与运动有关的左侧脑区,而期待的更新激活与控制有关的右侧脑区。

Temporal expectation is the ability of individuals to predict when the target stimulus will happen by using time infonaaation in the environment. The cognitive models of the temporal expectation can be classified into two categories. The first category, which includes trace-conditioning model, dual-process model, dynamic attending theory and temporal orienting model, focuses on the producing procedure of the temporal expectation. The other category, for example, strategy model and temporal re-orienting model, focuses on explaining the updating procedure of the temporal expectation. Researches about neural substrates of temporal expectation confirmed that different types of temporal expectation activate different cortex areas, which indicates the producing procedure and the updating procedure of temporal expectation are separated. The producing procedure activates the left inferior parietal and premotor areas, while the updating procedure activates the right prefrontal cortex.
