tijdsrekken

Tijdsrekken is a Dutch term that denotes processes or effects in which the duration of time is extended or perceived as longer. The term combines tijd (time) and rekken (to stretch). It is used in several contexts but is not a single formal scientific term.

In physics, the extension of time intervals due to relative motion or gravitation is typically called tijdsdilatatie (time dilation). In everyday Dutch, however, tijdrekken can appear as an informal way to describe the same phenomenon, especially for educational explanations; it is not standard terminology in scientific literature.

In media technology, tijdrekken commonly refers to time-stretching: changing the duration of an audio signal or video sequence without proportionally altering pitch or content. In audio processing, algorithms such as phase vocoder and WSOLA perform tijdrekken, enabling tempo changes for music and post-production. In video, time-stretching enables slow motion or fast-forward effects.

In psychology and perception research, tijdrekken may describe experiments on how attention, arousal, or expectancy affect the perceived duration of events; findings show that durations can appear longer or shorter than actual time depending on context.
