The Constructed Nature of Perception

Speaks to the constructed (and often subjective) nature of perception.

Why is The Distinction Between Physical and Perceptual Properties Important?

• They are not always equivalent

Response: Compression vs Expansion

Response Compression: as intensity increases, the percieved magnitude increases more slowly than the actual increase in intensity. (Brightness perception)

Response Expansion: as intensity increases, the percieved magnitude increases more quickly the actual increase in intensity. (Pain perception)

How do we Reduce Uncertainty about what’s happening in our enviroment?

• Active information gathering

• Predictive processing

How does context affect perception?

It works through top-down processing, where our expectations and surroundings guide what we percieve.

How does multimodal processing shape our perception?

It shapes perception by intergrating info from multiple senses into a single coherent experience.

McGurk effect

What we see influences hearing.

E.g. You see someone mouth one sound (far) but hear the sound (bar). Despite that, your brain creates a 3rd combined perception of the two stimuli.
