Study Notes
Perception Overview
- Perception is an active cognitive function that helps interpret sensory information and form an internal representation.
- It begins with sensation but is influenced by individual experiences and expectations.
Visual Perception
- The human optical system can detect approximately 7 million color variations.
- Colors are formed by combining three primary colors: red, green, and blue.
- Color hue corresponds to light wavelength; shorter wavelengths appear blue, while longer ones appear red.
- Brightness is perceived from the intensity of light waves; more intense waves are seen as brighter.
- Hermann von Helmholtz's trichromatic theory posits that three types of cones in the retina respond to different wavelengths (blue, green, red).
- The visual cortex compares signals from these cones to create color perception.
- Color blindness affects about 1 in 50 people, who cannot detect red or green hues.
Gestalt Principles of Perception
- Gestalt psychology emphasizes that perception is more than just the sum of visual components.
Principle of Figure-Ground
- People segment visuals into figure (focus) and ground (background), leading to different interpretations of images.
- This principle is used in design, such as the FedEx logo, which features an arrow symbolizing speed.
Principle of Proximity
- Objects that are close together are perceived as a group.
- Commonly applied in web design, such as grouping security icons on the Google Workspace landing page.
Principle of Similarity
- Similar-looking objects are mentally grouped together.
- This principle is utilized in navigation menus, where similar function links are color-coded (e.g., Zoom’s homepage).
Principle of Continuity
- We perceive objects arranged in continuous lines as related over those arranged jaggedly.
- Pinterest uses vertical columns to encourage scrolling and enhance user engagement.
Principle of Closure
- The mind fills in missing parts of an incomplete image, perceiving a whole object.
- Common in logos and website design, encouraging interaction as viewers seek to complete the imagery.
Principle of Past Experience
- Past experiences influence visual interpretations, though they vary among individuals.
- Colors or shapes can carry different cultural meanings; for example, a floppy disk symbol may not be recognizable to younger generations.
Types of Perception
- Sensory Perception: Involves detecting stimuli through sensory organs.
-
Extrasensory Perception (ESP): Perception without traditional sensory input, associated with intuition and a "sixth sense."
- Clairvoyance: Perceiving events without normal barriers (e.g., distance).
- Precognition: Predicting future events based on intuition or instinct.
- Psychokinesis: Influencing objects through mental concentration.
Psycho-Types of Perception
- Audial: Preference for information through hearing.
- Kinesthetic: Leads with touch as the primary sense.
- Visual: Primarily perceives through sight.
- Discrete: Thinks logically and numerically about the world.
- Synesthetic: Receives information through multiple senses, using them interchangeably.
