Mice monitor their timing errors.

Area of Science:

• Cognitive neuroscience
• Animal behavior
• Comparative psychology

Background:

• Animals exhibit goal-directed behaviors influenced by representational uncertainty.
• Temporal error monitoring, or tracking timing inaccuracies, is crucial for adaptive behavior.
• Limited research exists on non-human animals' temporal error monitoring capabilities.

Purpose of the Study:

• To investigate temporal error monitoring in mice.
• To determine if mice can track the direction and magnitude of their timing errors.
• To assess metacognitive sensitivity to temporal inaccuracies.

Main Methods:

• Developed a novel behavioral task for temporal production in mice.
• Minimized sensorimotor noise and favored temporal accuracy.
• Used reward expectancy as a proxy for confidence in timing performance.

Main Results:

• Mice showed high reward expectancy after accurate timing and low expectancy after inaccurate timing.
• Reward expectancy decreased symmetrically with deviations from the target interval (shorter or longer).
• Mice demonstrated sensitivity to both under- and overproduction of time intervals.

Conclusions:

• Mice possess a complete temporal error monitoring ability.
• Mouse metacognition exhibits human-like sensitivity to temporal errors.
• Findings advance understanding of metacognition in non-human animals.
