Prediction errors bidirectionally bias time perception.

Area of Science:

• Neuroscience
• Cognitive Science
• Decision Making

Background:

• Time perception and prediction errors are fundamental cognitive functions.
• The striatum, particularly the putamen, is implicated in both functions.
• A potential interaction between these processes within shared neural circuitry was hypothesized.

Purpose of the Study:

• To investigate the interaction between time perception and prediction errors.
• To identify the neural substrates underlying this interaction.
• To determine the effects of prediction errors on temporal judgments.

Main Methods:

• Utilized behavioral experiments to measure time perception under varying prediction error conditions.
• Employed neuroimaging techniques (e.g., fMRI) to observe brain activity.
• Applied computational modeling to analyze behavioral data and neural responses.

Main Results:

• Positive prediction errors increased perceived time (time dilation).
• Negative prediction errors decreased perceived time (time compression).
• The putamen was identified as the key brain region mediating this interaction.

Conclusions:

• Prediction errors significantly bias subjective time perception.
• This interaction occurs within the putamen, a part of the striatum.
• The influence of prediction errors on time perception can have both adaptive and maladaptive consequences depending on the context.
