Study Notes
Perception Overview
- Perception involves the brain interpreting sensory information rather than a direct reflection of reality.
- Cognitive biases influence our understanding of sizes and distances, demonstrated by the thumb and door example.
- Our brain compensates for distance perception using knowledge of objects' relative sizes.
Sensation vs. Perception
- Sensation refers to the raw data obtained through sensory modalities; perception is the interpretation of that data.
- Processing occurs in visual pathways where the brain differentiates between "what" objects are and "how" to interact with them.
Visual Pathways
- The what pathway (ventral stream) identifies objects, while the how pathway (dorsal stream) involves movements related to objects.
- Both pathways originate from the same early visual processing areas in the brain.
What-How Hypothesis
- Proposed by Goodale, this hypothesis suggests that spatial information is always available in visual processing, differentiating between object identification and interaction.
Development of Perceptual Awareness
- Eleanor Gibson highlighted how infants quickly develop perceptual awareness, including depth perception, despite limited prior knowledge.
- Direct perception aids in understanding others' emotions via instantaneous recognition of facial expressions.
Neuroscience Insights
- Mirror neurons fire shortly after visual stimuli, enabling recognition of others' actions and contributions to person perception.
- Specialized brain areas exist for recognizing faces, enhancing social interaction capabilities.
Machine Perception Challenges
- Computers struggle with handwriting recognition due to variable letter forms; template matching is effective for uniform characters like barcodes.
- CAPTCHAs help differentiate human users from machines, exploiting the limitations of machine vision.
Feature-Matching Theories
- Feature-matching theories propose we identify patterns by comparing unique features stored in memory rather than recognizing entire patterns.
- The Pandemonium Model involves "demons" analyzing stimulus features, reflecting a chaotic and concurrent processing system for perception.
