Summary: Why do we spend so much mental energy imagining scenarios that haven’t happened yet? A new theory proposes that future-oriented thinking — often called mental time travel — becomes a self-reinforcing habit because the brain’s reward system pays us for finding promising solutions in our minds. While this mechanism supports planning and problem solving, it can also be co-opted by anxiety and depression, producing chronic catastrophizing.
Professor Ekrem Dere of Ruhr University Bochum and Sorbonne Université argues that envisioning successful future outcomes triggers dopamine release, which rewards the cognitive effort and encourages repeated use of mental simulation. Published in Psychological Review on April 6, 2026, Dere’s self-reinforcement hypothesis frames mental time travel as a behavior shaped by operant conditioning: rewarding simulations are more likely to recur.
Key Facts
- The Self-Reinforcement Hypothesis: Predicting and simulating the future is mentally demanding. Dere suggests people engage in it because discovering a promising mental solution produces an internal reward, increasing the likelihood of repeating the behavior.
- Operant Conditioning: Similar to classic learning experiments, mental time travel is strengthened when it reliably produces an internal payoff — the expectation of relief, success, or problem resolution drives further simulation.
- The Dopamine Connection: The theory predicts that frequent future-oriented thinkers have a more responsive mesolimbic dopamine system, the brain circuit most closely tied to reward processing.
- The Dark Side — Catastrophizing: When this reward loop is hijacked by negative simulations, people may repeatedly imagine worst-case outcomes, reinforcing fear, avoidance, and safety behaviors that maintain or worsen anxiety and depression.
- Therapeutic Potential: If future-oriented mental time travel follows learning principles, psychotherapy could intentionally reinforce constructive simulations and weaken the reward of catastrophizing, helping patients rewire maladaptive habits of thought.

Why imagine the future? Envisioning yourself in possible future situations helps anticipate consequences and select actions today. Some people do this regularly; others rarely engage in deliberate foresight. Dere’s hypothesis offers a mechanistic explanation for those individual differences.
According to Dere, when mental time travel yields a seemingly promising plan or solution, the brain’s reward system responds. That internal payoff makes the plan easier to recall and strengthens the tendency to use mental simulation again, gradually shaping a person’s habitual approach to problems.
This perspective can be tested empirically: people who habitually mentally travel to the future should show greater reactivity in reward-related brain regions, particularly the mesolimbic dopamine pathway, observable with functional neuroimaging.
Mental time travel and mental health
The same reinforcement mechanisms that make constructive planning effective can also preserve maladaptive patterns in psychopathology. When people ruminate on negative past events and repeatedly project those outcomes forward, the reward loop can inadvertently reinforce catastrophizing. These negative simulations generate distress, erode self-image, and promote avoidance and safety behaviors that maintain a disorder. Dere emphasizes that recognizing and interrupting these harmful cycles should be a therapeutic priority.
Psychotherapy could therefore be reframed as a form of behavioral retraining for the reward system: by repeatedly practicing adaptive, solution-focused simulations and reducing reinforcement for catastrophic thinking, clinicians may help clients cultivate healthier future-oriented thinking habits.
Key Questions Answered:
A: There is an important distinction between planning and worrying. Finding a viable solution in your mind produces a rewarding dopamine response. Catastrophizing, by contrast, repeatedly reinforces fear without yielding solutions; the brain’s reinforcement mechanism thus sustains anxious, stress-inducing loops rather than relief.
A: Yes. If future-oriented simulation follows principles of learning, targeted psychotherapeutic practice can strengthen adaptive simulations and weaken the reward of catastrophic “what-if” thinking. Deliberate practice of constructive scenarios helps rewire reward associations.
A: Possibly. People with a more responsive reward system may experience stronger reinforcement from the “aha” of a good plan, motivating frequent mental simulation. Those who prefer living in the moment may simply receive less immediate reward from the cognitive effort of simulating future outcomes.

Abstract
Future-oriented Mental Time Travel and Self-reinforcement
Future-oriented mental time travel is an adaptive cognitive capacity that makes life more predictable, effective, and rewarding. It helps people avoid harm and cope with social and professional challenges. Yet individual differences remain: some people habitually plan and simulate possible futures, while others prefer spontaneous approaches.
The self-reinforcement hypothesis draws on behaviorist learning theory to explain these differences. It proposes that successful mental simulations activate reward circuitry, reinforcing future-oriented thinking and making it more likely to recur. The article discusses potential neurophysiological substrates for this mechanism and outlines experimental approaches to test the idea, including neuroimaging of reward-system reactivity.
