  • The diminished sensitivity to a stimulus after constant exposure
  • The process of interpreting sensory data

9. What is "gestalt perception"?

  • The idea that perception is constructed from basic sensory inputs
  • The theory that people perceive things based on social influences
  • The belief that the whole is greater than the sum of its parts
  • The process of interpreting information through top-down processing

10. What is the "Stroop Effect"?

  • The delay in reaction time when the color of a word differs from the word itself
  • The tendency to recall words that are emotionally significant
  • The effect of emotional context on memory
  • The process of enhancing sensory perception through training

11. What type of visual illusion is the "Ponzo illusion"?

  • An illusion where two horizontal lines appear to be of different lengths due to converging lines
  • An illusion where circles appear to be squares
  • An illusion that makes objects appear to rotate
  • An illusion where colors change with different lighting

12. What is the "Phi phenomenon"?

  • The illusion of movement created when two stationary lights blink on and off in sequence
  • The perception of depth from the visual cues in the environment
  • The sensation of motion in still images
  • The effect of light on color perception

13. Which of the following describes "depth perception"?

  • The ability to determine the size of objects in the environment
  • The ability to see objects in three dimensions and judge distances
  • The process of recognizing familiar objects
  • The ability to interpret sound cues in the environment

14. What is the role of "theories of attention" in perception?

  • They explain how we focus on relevant stimuli and ignore irrelevant ones
  • They describe the process of encoding information into memory
  • They analyze how memory systems function in depth
  • They assess the role of the brain in interpreting stimuli

15. What is an example of "change blindness"?

  • Failing to notice a change in a visual scene after a brief interruption
  • Recognizing subtle changes in facial expressions
  • Noticing the change in color of an object over time
  • Identifying minute details in a busy environment

16. Which of the following is true about "visual processing"?

  • It involves converting light signals into electrical signals for interpretation by the brain
  • It is limited to the detection of color and shapes only
  • It occurs only in the occipital lobe of the brain
  • It does not involve attention or memory systems

17. What is the "Ames room" illusion?

  • A distorted room that creates the illusion of varying sizes of people or objects based on perspective
  • An illusion where people appear to shrink in size due to the surrounding objects
  • A visual illusion created by colored light reflecting off objects
  • A mental illusion where an image cannot be processed correctly

18. Which phenomenon explains why we perceive movement in stationary images?

  • The persistence of vision
  • The principle of constancy
  • The change blindness effect
  • The phi phenomenon

19. The "Ebbinghaus illusion" involves the perception of which of the following?

  • A circle surrounded by smaller circles appearing larger than one that is surrounded by larger circles
  • The illusion of rotating shapes in static images
  • The change in perception of an object due to emotional states
  • The inability to perceive depth correctly

20. In the context of visual illusions= what does the term "size constancy" refer to?

  • The ability to judge the size of an object regardless of its distance from the observer
  • The ability to perceive objects as moving even when they are stationary
  • The tendency to perceive objects in their original shape despite changes in perspective
  • The ability to distinguish between near and far objects

21. What is "color constancy"?

  • The perception of an object’s color as constant= even when the lighting changes
  • The ability to distinguish between colors in a monochromatic image
  • The change in color perception due to physical stimuli
  • The tendency to associate colors with emotional states

22. In terms of visual perception= what is "perceptual set"?

  • The tendency to perceive objects in a certain way due to previous experiences or expectations
  • The phenomenon of sensing and responding to stimuli
  • The process of recognizing familiar patterns in the environment
  • The ability to judge spatial relationships

23. In the context of visual illusions= what is "figure-ground perception"?

  • The ability to distinguish objects from their background
  • The process of recognizing facial expressions
  • The inability to perceive shapes correctly
  • The ability to focus on auditory stimuli while ignoring visual ones

24. What does the term "sensation" refer to in perception?

  • The process of interpreting sensory data
  • The initial detection of stimuli by sensory organs
  • The ability to recognize familiar objects
  • The brain’s organization of sensory input
