Corrigendum: Perceived Impact as the Underpinning Mechanism of the End-Spurt and U-Shape Pacing Patterns

Text CorrectionIn the original article, there was an error. **In equations (1) and (2), the nominator should have been 1. In addition, the text should clearly indicate this fact.**A correction has been made to **FORMULATION OF THE PERCEIVED IMPACT MECHANISM**, **Paragraph Number 1**:** To illustrate, perceived impact of a step in goal-pursuit can be stated formally by a simple function. For example, let a step be equal to one, s be a series of numbers in an increasing order, representing the index of each step steps in goal-progress (e.g., s = 1, 2, 3, 4, 5, 6, 7), and 〖PI〗_(s_i ) a number between 0 to 100, representing the percent of perceived impact of the current step s_i (e.g., 〖PI〗_(s_i ) = 50%; representing the impact of the currnent step out of the maximum possible impact a step can have on goal-progress). Accordingly, min(s) and max(s) are the smallest and highest values in s, which represent the starting- and ending-points, respectively. According to the small area principle, people use the nearest reference point, and tend to switch between the beginning and ending points in the middle of the task. Therefore, if s_i〖PI〗_(s_i )=(s_i 1)/(min (s)+s_i ) (1)Else:〖PI〗_(s_i )=(s_i 1)/(max (s) - s_i ) (2)**
