• Results
• Perceptual Learning
• Improved by 60 across all noise levels
• Threshold vs. Noise Curve
• Increase in sampling efficiency (630, 240)
• Decrease in spatial distortion (0, 30)

• Methods
• Subjects
• Visual Stimulus
• 8 patches/ segment
• SF 10 cpd
• Gaussian positional noise
• Task Identify the
• misaligned pair of segments
• out of the 3 choices
• Threshold Measurement
• A modified staircase method to control the offset
  magnitude track the threshold
