motion perception

Examples of motion perception in the following topics:

• Perceiving Motion

  • Motion perception is the process of inferring the speed and direction of elements in a scene based on visual input.
  • Motion perception happens in two ways that are generally referred to as first-order motion perception and second-order motion perception.
  • First-order motion perception occurs through specialized neurons located in the retina, which track motion through luminance.
  • However, this type of motion perception is limited.
  • Due to first-order motion perception, the luminous impulses are seen as a continual movement.

• Cerebral Hemispheres and Lobes of the Brain

  • Other areas of the occipital lobe are specialized for different visual tasks, such as visuospatial processing, color discrimination, and motion perception.

• Perceiving Depth, Distance, and Size

  • Perception of depth, size, and distance is achieved using both monocular and binocular cues.
  • In reality, perception and vision are far more complicated than that.
  • Depth perception is the visual ability to perceive the world in three dimensions, coupled with the ability to gauge how far away an object is.
  • Depth perception, size, and distance are ascertained through both monocular (one eye) and binocular (two eyes) cues.
  • The Ebbinghaus illusion illustrates how the perception of size is altered by the relative sizes of other objects.

• Vision: The Visual System, the Eye, and Color Vision

  • All vision is based on the perception of electromagnetic rays.
  • Color vision is a critical component of human vision and plays an important role in both perception and communication.
  • Depth perception refers to our ability to see the world in three dimensions.
  • While depth perception is often attributed to binocular vision (vision from two eyes), it also relies heavily on monocular cues (cues from only one eye) to function properly.
  • These cues range from the convergence of our eyes and accommodation of the lens to optical flow and motion.

• Social Perception

  • Social perception is a kind of perception that allows one to understand other people, social cues, and non-verbal cues in their environment.
  • These perceptions can influence an individual's behaviors and attitudes.
  • Social perceptions of others are compared to self perceptions to give an individual a better understanding of where he or she falls in society.
  • While the most simplistic view of social perceptions involves one individual's perception of another, it can also refer to an individual's perception of a group, a group's perception of an individual, or a group's perception of another group.
  • Describe how perception is linked to the process of social cognition.

• Introducing the Perception Process

  • Perception is the set of unconscious processes we undergo to make sense of the stimuli and sensations we encounter.
  • All stages of the perception process often happen unconsciously and in less than a second.
  • Thus, the first step of perception is the (usually unconscious, but sometimes intentional) decision of what to attend to.
  • An ambiguous stimulus may be translated into multiple percepts, experienced randomly, one at a time, in what is called "multistable perception."
  • Rubin's Vase is a popular optical illusion used to illustrate differences in perception of stimuli.

• Cultural Influences on Perception

  • However, our perceptions of our emotions are affected by culture.
  • Two theories of social perception are Attribution theory and Social Comparison theory.
  • Motivational factors also influence perceptions both positively and negatively.
  • The feelings we have influence our perceptions of places, situations, people, objects, etc.
  • Identify examples of how emotions, goals, and culture influence our perception

• Unconscious Perception and Influences on Behavior

  • Our brains take in more information than we are consciously aware of, which influence our perceptions and behaviors.
  • Perception is the process by which the mind selects, organizes, and interprets sensations.
  • It affects our behavior because perception allows us to assess situations and decide on suitable reactions.
  • Therefore, much of our perception is based on unconscious processes.
  • A hypnotic trance state is an example of unconscious perception influencing behavior.

• Introduction to Social Psychology and Social Perception

  • Social psychology focuses on the importance of individual or social influences on a person's perception of the world around them.
  • Social perception allows individuals to make judgments and form impressions about other people.
  • Social perceptions can influence an individual's behaviors and attitudes.
  • This includes areas like social perception, social interaction, and social influence (including trust, power, and persuasion).
  • There is a strong interest in how perceptions and thoughts, as well as social cues, affect individual behavior in this area.

• Unconscious Perception

  • We encounter more stimuli than we can attend to; unconscious perception helps the brain process all stimuli, not just those we take in consciously.
  • Unconscious perception involves the processing of sensory inputs that are not selected for conscious perception.
  • A number of studies have examined how unconscious stimuli influence human perception.
