Perceptions
Definition
Perception, psychologically speaking, is a person's sensory experience of the world, including their ability to identify and understand sensory data. This include one's reaction to those stimuli as well. The senses of vision, touch, hearing, smell, taste, and orientation are all part of perception. All of these senses are used to fully understand the environment and adapt to its needs.
Generally speaking, perception is formed in a few processes.
The first is an external stimulus, like a dog barking, that the sensory organs can perceive. The ears will be in charge of detecting the stimuli in this instance. The attended stimulus will be converted from auditory information into neurological impulses and sent to the brain through a transducer if the person listens to the bark, interpreting it as a sound of the dog. Then the person will then respond to the situation according with their knowledge and experience with a dog barking. If the individual is afraid of dogs, then he/she might decide to leave right away or keep a longer distance from the animal.
Proximity
Proximity refers to the principle that objects that are close together in space tend to be seen as distinct from other objects. In the context of perception, when objects are grouped closely together, our mind naturally perceives them as belonging to the same group or category.
EX-For instance, let's say you have three circles close to each other on the left side of the picture, and two circles on the right side. Due to the principle of proximity, you would perceive the three closely grouped circles as one distinct object and the two circles on the right as another distinct object.
Similarity
Similarity refers to the principle that objects that share similar visual features tend to be grouped together and perceived as part of the same category or object. When objects have similar shapes, colors, textures, or patterns, our mind naturally groups them together based on their shared characteristics.
EX- For example, let's say you have a picture with various shapes, including circles, squares, and triangles. If all the circles in the picture have the same color and size, while the squares and triangles have different colors and sizes, the principle of similarity would lead us to perceive the circles as a distinct group separate from the squares and triangles.
Closure
Closure refers to the principle that our mind tends to perceive incomplete or fragmented visual stimuli as complete and whole objects. When presented with partial information, our brain fills in the missing gaps to create a meaningful and coherent perception.
EX- For example, imagine you have a picture that shows a square with one of its corners missing. Despite the missing corner, our brain automatically fills in the gap and perceives the square as a complete and closed shape.
Good Continuation
Good continuation means that our minds tend to focus on lines and patterns that are smooth and continuous rather than ones that are abrupt or shattered. We consider lines or objects to be related or a part of a continuous shape when they seem to follow the same path.
EX- If two lines cross each other, we tend to see them as two separate, unbroken lines rather than interpreting them as sudden changes in direction at the intersection.
Common Movement (Also Known as Common Fate)
Common movement refers to the fact that when elements travelling in the same direction or at the same speed are regarded as a group or a component of the same object. This concept helps in the recognition of relationships and patterns in dynamic visual scenes.
EX- Instead of being viewed as separate birds, a flock of birds flying in the same direction is viewed as one unit. Despite the fact that some birds are far away, their common motion connects them.
Good Form
Good Form, also known as Pragnanz, states that humans interpret images in the most systematic and simplest manner possible. Complex visuals are typically interpreted by our brains in a way that produces symmetrical, secure, and familiar forms.
EX- When looking at the Olympic rings, or at the Audi logo, we perceive them as five interlocking circles rather than a collection of separate curved lines, because circles are a simple and familiar shape.
Symmetry
The principle of symmetry suggests that our brain prefers symmetrical and orderly visual arrangements. Symmetry gives a sense of stability, harmony, and completeness in what we perceive.
EX- A symmetrical logo, like a butterfly shape, is easier to recognize and feels more balanced than an irregular or asymmetrical design.
Figure-Ground
Figure-ground refers to how we differentiate between the main subject (figure) and the background (ground). Our perception automatically distinguishes objects from their surroundings, allowing us to focus on what’s most important in a visual scene.
EX-In Rubin’s Vase illusion, you can either see a white vase or two black faces looking at each other, depending on which area you interpret as the figure and which as the background.
