The MTT task is a neuroscience measure designed to assess an individual's capacity for mental time travel. It typically involves presenting participants with a series of event cues and asking them to generate specific events from their own personal past or future that are related to each cue. For example, participants may be shown cue words such as "graduation" or "vacation" and then asked to recall a specific past event or imagine a specific future event related to each cue.
In this task, the individual's present moment serves as a reference point from which they situate and retrieve personal versus general events. Personal events refer to specific episodic memories from the individual's own life, such as a birthday party or a family trip, while general events are more abstract and can be shared by multiple individuals, such as historical events or holidays.
The MTT task taps into several cognitive processes and neural mechanisms associated with mental time travel. It requires the retrieval of specific episodic memories or the construction of plausible future scenarios. The task engages memory processes, including recall and recognition, as well as imagination and prospective thinking.
Neuroimaging studies have shown that the neural substrates underlying MTT involve a network of brain regions.
The MTT task has been used in research to investigate individual differences in the capacity for mental time travel and how it relates to various cognitive processes, such as autobiographical memory, imagination, planning, and self-projection. It has also been employed to examine the effects of aging, neurodegenerative diseases, and psychiatric disorders on mental time travel abilities.

Neuroimaging studies have shown that the neural substrates underlying MTT involve a network of brain regions.
- PFC: cognitive control and executive function required for retrieving and manipulating temporal information.
- Hippocampus and MTL: formation and retrieval of episodic memories
