Visual Encoding: 10 Examples and Definition

visual encoding examples and definition

Visual encoding refers to the cognitive process by which humans convert visual stimuli, such as images, objects, or scenes, into a mental representation that can be stored and retrieved within the memory system.

This mechanism is essential for transforming visual information, including colors, shapes, and spatial relationships, into accessible data that can be encoded and retained within an individual’s neural networks.

Visual encoding is vital in various cognitive functions, such as object recognition, spatial navigation, and visual working memory.

Although the brain may not recall each minute detail consciously, it can retain the overall composition, color palette, and emotional impact of a visual experience.

Visual encoding is an indispensable component of human learning and memory recall. Without visual encoding, the formation and preservation of memories would become considerably more challenging.

Visual Encoding Definition

Visual encoding refers to the neurocognitive mechanism by which visual stimuli are converted into mental representations, thereby enabling their storage and retrieval within the human memory system.

This process serves as the backbone of transforming visual information, such as pictures, objects, or scenes, into data that can be decoded and stored within an individual’s neural networks.

Makhijani (2020) describes visual encoding as:

“…the process of converting images and visual sensory information to the memory stored in the brain.” (p. 47).

Upon perceiving visual stimuli, the human brain processes and encodes the visual data, subsequently storing it within the memory system for later recall. This fundamental process plays a critical role in how humans retain information.

Bedford and Sanchez (2020) argue that:

“…visual encoding refers to the process by which we remember visual images” (p. 115).

Visual encoding is integral to various cognitive functions, including object recognition, spatial navigation, visual working memory, and the retention and interpretation of faces, objects, landscapes, and written words.

Simply, visual encoding constitutes the cognitive process responsible for converting visual input into a format that can be readily recalled, thereby allowing individuals to assimilate and comprehend visual experiences efficiently.

10 Visual Encoding Examples

  • Picture encoding: Visual encoding involves our brains processing and filing away images or pictures. For instance, when we look at a picture of someone dear to us: details like their facial features, clothing selection, and environment are saved by the brain’s visual encodings.
  • Color encoding: The brain can encode colors, enabling us to perceive and recall different hues. For instance, when we see a sunset, our brain encodes the colors of the sky, such as red, orange, and pink.
  • Spatial encoding: Our brain can encode visually by forming a mental map of positions and spatial relationships when navigating a new city. Doing this allows us to retain information better and locate our way back, even in unknown territory.
  • Object encoding: If we see a complex object, such as an airplane, our brain encodes its components and shape of it. It allows us to quickly recognize an object in the future, even when viewed from different angles.
  • Face encoding: When we meet someone for the first time, our brain encodes their facial features and expressions. So, the next time we meet, our brain can rapidly recognize them even if they have changed their hairstyle or clothing.
  • Motion encoding: If we watch a video or movie, our brains can encode and remember an object’s movements on-screen. When playing a game, for example, this type of visual encoding helps us remember our characters’ movements and guide them in the right direction.
  • Pattern encoding: This type of visual encoding involves processing and remembering patterns and designs, such as stripes or polka dots. For example, when we see a shirt with a specific pattern, our brain encodes it to help us recognize it later.
  • Depth encoding: Our remarkable brain gives us the ability to store depth perception and discern the relative position of objects in our immediate view. As an example, when viewing a 3D sculpture, we acknowledge not only its form but also each component’s exact location within it.
  • Symbolic encoding: When viewing symbols, the brain can encode them to help us later recognize and understand their meaning. For example, when we see a mathematical equation written on paper, our brain encodes it to help us solve it quickly.
  • Contextual encoding: If we view a scene, our brains can encode the context of that particular moment. For example, when we see a painting in a museum, our brain encodes the environment by taking in factors like lighting, temperature, and sound. 

Gestalt Theory on Visual Encoding

According to Gestalt theory, the human brain processes visual information by organizing it into meaningful patterns and structures rather than processing individual components in isolation. This organization of visual elements is known as “Gestalt grouping.”

Gestalt theory emerged in the early 20th century as a response to the reductionist approach of structuralism and behaviorism in psychology.

The pioneers of Gestalt theory, such as Max Wertheimer, Wolfgang Köhler, and Kurt Koffka, emphasized the importance of studying perception as a whole rather than breaking it down into isolated parts (Peterson & Berryhill, 2013).

The core principle of Gestalt theory is that the brain organizes visual stimuli into coherent and meaningful patterns based on a set of principles or “laws of grouping.” These principles include:

  • Similarity When our mind perceives things that appear similar (in shape, size, or another property) as part of a group.
  • Proximity When our mind perceives things that are close to one another as part of a group.
  • Continuity When our mind perceives things that form a continuous pattern as part of a group.
  • Closure When our mind processes unbroken lines and shapes as cohesive closed shapes by cognitively closing the loop. This is a mental heuristic.
  • Symmetry When our mind perceives symmetrical items as part of a group.
  • Connectedness When our mind perceives items that are physically connected to one another as part of a group.

Gestalt theory proposes that the brain automatically and unconsciously applies these grouping principles to incoming visual information, creating a holistic and coherent representation of the visual scene  (Peterson & Berryhill, 2013).

Gestalt theory also suggests that visual perception is not a passive process but an active one, involving constant interpretation and analysis of visual stimuli based on prior knowledge and experience.

Benefits of Visual Encoding

Visual encoding offers numerous advantages over other information retrieval and memory storage forms, including better recall of information, faster encoding, increased accuracy, enhanced comprehension, and improved communication.

Here are five key benefits of visual encoding: 

1. Improved Recall of Visual Information

Visual encoding enhances the retention of visual information as the brain processes this type of data more efficiently than other forms, such as verbal or spatial, resulting in a faster and more accurate recall (Li et al., 2020).

2. Faster Encoding

Rapid encoding occurs when symbols and patterns are visually presented, allowing for quicker processing and storage of information than other encoding methods.

Often, visualizations through graphs or other visual cognitive tools can portray very complex concepts in a simple and fast manner through imagery (for example, a family tree is easier to demonstrate relationships between family members than trying to explain each relationship independently).

3. Increased Accuracy

Visual encoding leads to increased accuracy in a recall, which can enhance decision-making and problem-solving skills by relying on accurate visual information (Li et al., 2020).

4. Enhanced Comprehension

Visual encoding aids in comprehending complex concepts by allowing the brain to process visual information more quickly than other forms of data.

5. Improved Communication

Visual encoding can enhance communication by presenting information visually, which is easily understood by a wide range of audiences and can reduce confusion often associated with verbal or written communication.

Limitations of Visual Encoding

While visual encoding can be an effective way to store and retrieve information, it is essential to note that the method has limitations, such as subjective interpretation, limited capacity, misleading visuals, and cultural barriers.

Here are five critical limitations of visual encoding:

1. Limited by Visual Perception

Visual encoding takes advantage of the brain’s natural capacity to decode and understand visual information, which may be heavily influenced by age, sight impairments, or cognitive aptitude (Xia et al., 2022).

Such elements can greatly diminish its efficiency in certain individuals or groups.

2. Subjective Interpretation

Visual encoding is a deeply personalized experience, as one’s understanding and recollection of visual information could be affected by their own life experiences and worldviews.

As such, individuals may have diverse levels of knowledge when it comes to processing visual data (Bresciani & Eppler, 2015).

3. Limited Capacity

Although visual encoding can help us recall information more easily, there is a cap to the number of visuals our minds can store. Overwhelming the brain with excessive visual data may cause cognitive overload and impede how much we remember.

4. Misleading Visuals

Visual encoding can be tricky if the visuals used are not accurate or are presented in a way that distorts the information, leading to incorrect conclusions and decision-making (Xia et al., 2022).

5. Cultural and Linguistic Barriers

Visual encoding can be limited by cultural and linguistic barriers, as certain symbols or visual representations may have different meanings or interpretations across cultures and languages (Bresciani & Eppler, 2015).

Such a situation can lead to misunderstandings and miscommunications when using visual encoding in a diverse context.

Strategies to Improve Visual Encoding

Creative strategies are available to help capitalize on the advantages of visual encoding while reducing its weak points. For example, strengthening attention and focus, as well as multisensory encoding, can assist in enhancing comprehension and remembrance of visuals.

Here are the most common strategies used to improve visual encoding:

1. Attention and Focus

To improve visual encoding, individuals can allocate their attention and focus to the presented visual information. Active engagement with the visual stimulus and minimizing distractions can aid in the process (Heuer & Schubö, 2016).

For instance, when trying to remember a chart or graph, one can spend more time analyzing it closely and identifying patterns and trends in the information presented.

2. Organization and Categorization

Another strategy to improve visual encoding is to organize and categorize information. It can involve grouping similar visual elements or using mnemonic devices to remember visual input.

For example, when learning the colors of the rainbow, people often use the acronym “ROYGBIV” to remember the order of the colors.

3. Repetition and Practice

Repetition and practice are effective techniques for improving visual encoding. Repeated exposure to visual stimuli, such as flashcards or diagrams, can reinforce the neural pathways related to that information (Magen & Berger-Mandelbaum, 2018).

For example, when learning a new language, repeatedly practicing vocabulary words with flashcards can enhance the visual encoding of those words, facilitating their retrieval and recognition in the future.

4. Multisensory Encoding

Combining visual encoding with other sensory modalities, such as sound or touch, can improve memory retention.

For example, when learning a new dance routine, watching a video of the routine while listening to the music can enhance visual encoding of the dance steps.

Other Types of Encoding

Additional types of encoding include:

Type of EncodingDescription
Visual encodingInvolves using visual cues to store information and acoustic means using sound or language to store information.
Semantic encodingInvolves using meaning or context to store information. We store the meaning along with the term, date, or concept to make it more memorable.
Acoustic encodingInvolves using auditory cues to store information. Includes linking sound characteristics such as pitch and frequency to the data being stored.
Elaborative encodingInvolves connecting new information to prior knowledge to remember it. Contrasted to rote learning where facts are remembered in isolation.
Tactile encodingRefers to using physical sensations and touch to store information.
Organizational encodingInvolves organizing information into groups or categories. 


Visual encoding plays a crucial role in human cognition by converting visual stimuli into mental representations that can be stored and retrieved in memory. 

Visual encoding is essential for object recognition, spatial navigation, and visual working memory, among other cognitive functions. 

The Gestalt theory emphasizes the importance of studying visual perception as a whole rather than breaking it down into isolated parts. 

Visual encoding offers several advantages, including better recall of information, faster encoding, increased accuracy, enhanced comprehension, and improved communication. 

However, visual encoding has limitations, such as subjective interpretation, limited capacity, misleading visuals, and cultural and linguistic barriers. 

Still, strategies such as attention and focus, organization and categorization, repetition and practice, and multisensory encoding can be used to overcome these limitations.
