1.2.4 Visual Illusions

• The Müller-Lyer illusion is an example of a distortion in visual perception.
• Match the cause of visual illusions with their descriptions:

  Context Effects ↔️ Surrounding environment influences perception

  Depth Cues ↔️ Visual cues to perceive distance

  Gestalt Principles ↔️ Grouping elements based on proximity

  Pattern Recognition ↔️ Identifying familiar shapes
• What is one principle of Gestalt psychology that can cause visual illusions?

  Closure
• What causes physiological illusions?

  Brain processing of stimuli
• What visual cue causes the Ponzo illusion?

  Depth cues
• What are visual illusions?

  Distortions of visual perception
• What does the Necker cube demonstrate about visual illusions?

  Misinterpretation of visual cues
• The Müller-Lyer illusion demonstrates the influence of context effects on visual perception.
• The Müller-Lyer illusion shows how lines with different arrow ends appear to have different lengths.
• In the Ponzo illusion, identical lines between converging parallel lines appear different in size.
• The Müller-Lyer illusion is caused by context effects.
• Match the characteristic of visual illusions with its description:

  Distortion ↔️ Alterations in size, shape, color, or depth

  Misinterpretation ↔️ Incorrect understanding of visual cues

  Reliance on Assumptions ↔️ Using contextual information to fill in gaps
• Match the type of visual illusion with its description:

  Contextual Illusions ↔️ Surrounding environment influences perception

  Optical Illusions ↔️ Result from light interacting with our eyes

  Physiological Illusions ↔️ Arise from brain processing visual stimuli
• What is pareidolia an example of?

  Pattern Recognition
• Visual illusions occur when our brains use shortcuts while processing visual information.


  True
• Reliance on assumptions is a common cause of visual illusions.

  True
• The Ponzo illusion uses converging parallel lines to distort perceived size.


  True
• Match the type of visual illusion with its example:

  Contextual Illusions ↔️ Müller-Lyer illusion

  Optical Illusions ↔️ Mirage

  Physiological Illusions ↔️ Afterimages
• The Necker cube can be perceived as facing either up-left or down-right due to ambiguous depth orientation.


  True
• Converging lines in the Ponzo illusion make objects at the top appear larger.


  True
• Context effects in visual illusions occur when the surrounding environment influences perception
• What is the cause of the Müller-Lyer illusion?

  Context Effects
• Research on visual illusions can provide insights into the brain's mechanisms for interpreting visual information.


  True
• Visual illusions occur when our brains use shortcuts or assumptions while processing visual information
• Gestalt principles group visual elements based on proximity and closure.


  True
• Depth cues such as convergence are used to perceive distance
• Match the application of visual illusion research with its description:

  Art and Design ↔️ Manipulate perception creatively

  User Interface Design ↔️ Create effective and intuitive interfaces

  Advertising and Marketing ↔️ Influence consumer perceptions
