Week 3: Object and scene perception

Question 1

Perception

Answer 1

• information from receptors → feature Analysis (detection) → Interpretation →
  → Identification (recognition) & Significance based on Memory
• Interpretation happens automatically
• Individual difference in “significance”
• “Significance” is determined based on person’s previous experiences
• Perception is limited by previous experiences (knowledge) of individuals
• Perception is also influenced by emotions, motives and expectations
  → That is why “Every individual can have different opinions”

Question 2

Perceptual organization

Answer 2

• The process of analyzing, integration or organizing of incoming information
• Scene is a continuous array of light intensity values → needs to extract a
  meaningful entities & objects
• Local differences in orientation or spatial frequency are harder to compute
  → require higher order comparisons between the feature-selective responses of different
  populations of neurons
  → early cortical visual areas. → area V1.
