Forward and backward prediction in learning and perception

Area of Science:

• Cognitive Neuroscience
• Computational Psychology
• Machine Learning

Background:

• Predictive processing frameworks highlight forward prediction for learning and perception.
• Anticipating future sensory events based on past/current input refines environmental estimates and predictions.
• Statistical learning research shows backward predictive relationships are learned equally well.

Purpose of the Study:

• To explore the role of forward and backward predictive relationships in learning and perception.
• To question the privileged status of forward-looking mechanisms in predictive processing.
• To compare the implications of forward and backward predictions for cognitive processes.

Main Methods:

• Theoretical discussion and synthesis of existing research in predictive processing and statistical learning.
• Analysis of computational implications for learning and perceptual inference.
• Comparative analysis of forward vs. backward predictive mechanisms.

Main Results:

• Both forward and backward predictive relationships are effectively learned.
• Forward predictions are crucial for perceptual inference and learning.
• Backward predictive relationships are learned but not explicitly retrieved during perception.

Conclusions:

• Forward and backward predictive relationships contribute to learning.
• Perception primarily retrieves future predicted states, not past ones.
• The privileged status of forward prediction in perception is challenged by the equal learning of backward relationships.
