Intention-based and sensory-based predictions.

Area of Science:

• Cognitive Neuroscience
• Computational Neuroscience
• Psychology

Background:

• Adaptation to environmental changes requires predicting future states.
• Predictions can be sensory-based (learning relationships between events) or intention-based (acting to produce effects).
• It remains unclear if these prediction types are processed independently or integrated.

Purpose of the Study:

• To investigate whether sensory-based and intention-based predictions are processed independently or combined.
• To examine how the brain processes prediction errors when these two prediction types conflict.

Main Methods:

• An experiment was designed where participants predicted a final tone in a sequence.
• Predictions were based on preceding tones (sensory) and/or the participant's intention.
• The congruence between sensory and intention-based predictions was manipulated.

Main Results:

• Prediction error responses were similar regardless of whether sensory or intention-based predictions were violated.
• This indicates that both sensory and intention-based predictions are formulated and coexist simultaneously.
• Violations of intention-based predictions elicited additional, later error responses compared to sensory-based prediction violations.

Conclusions:

• Sensory and intention-based predictions are integrated into a common predictive process.
• The brain processes violations of intention-based predictions differently, suggesting a distinct role for intentionality in predictive coding.
• These findings advance our understanding of adaptive behavior and predictive processing in the brain.
