Study Notes

Perceptual Errors

  • Perceptual errors occur when our perception does not match reality due to various factors such as cognitive processes, environmental conditions, and individual differences.

Types of Perceptual Errors

  • Illusions: visual deceptions caused by the interaction between physical stimuli and the brain's interpretation of those stimuli.
    • Examples: Müller-Lyer illusion, Kanizsa triangle, and Ponzo illusion.
  • Misperceptions: incorrectly attributing properties or characteristics to objects or situations based on existing knowledge and beliefs.
    • Examples: thinking someone is winking when they are just blinking, or assuming a person is angry when they are simply tired.
  • Attentional Blindness: failing to notice obvious events occurring right in front of them because of focused attention elsewhere.
    • Famous example: the video showing two basketball teams playing, and most people fail to notice the gorilla entering the scene.
  • Change Blindness: inability to detect changes in visual scenes, especially when there are similarities between the original and altered images.
    • Example: failing to notice the difference between two similar cars.

Causes of Perceptual Errors

  • Physical Factors:
    • Poor lighting, distance, angle of view, and size can influence perception.
    • Example: an object may look smaller from a distance.
  • Psychological Factors:
    • Past experiences, expectations, emotions, and cognitive biases can lead to perceptual errors.
    • Example: perceiving food differently based on past experiences.
  • Brain Processes:
    • Attention allocation, memory retrieval, and mental imagery can contribute to perceptual errors.
    • Example: overlooking details when focusing on one aspect of a situation.
