The ability to group objects into categories is a fundamental aspect of human perception and cognition. This process of categorisation begins early in life, with infants as young as 12 months old demonstrating the ability to categorise objects based on shape. As children mature, they progress from basic-level to superordinate-level categorisation, aligning more closely with the categories recognised by adults. The formation of categories is influenced by factors such as perceptual similarities, functional similarities, and linguistic labels. For example, the objects lizard, kangaroo, and salmon can be grouped into the same perceptual category due to shared characteristics. Understanding these categorisation processes is crucial in fields such as design and psychology, where principles like the Gestalt laws of perceptual organisation guide the creation of effective visual displays and enhance our understanding of human perception.

What You'll Learn
Lizard, kangaroo, salmon
The grouping of lizard, kangaroo, and salmon is an example of a sparse category, where members have very few common features. The rest of the features vary independently and contribute to "surface" variance. Other examples of sparse categories include mathematical and scientific concepts. For instance, an increase in a fish population in a pond and interest accumulation in a bank account are both instances of exponential growth, despite having no other features in common.
The ability to group items into categories is a form of deep semantic processing that can lead to memory intrusions, such as false recognition and recall of non-presented items. This grouping is a natural compulsion to find order in disorder. In the case of lizard, kangaroo, and salmon, the category may be based on a shared superordinate feature, such as "animal".
Children as young as 12 months old can categorize objects by shape, although they often focus on specific parts of an object rather than the whole. By the age of three, children can categorize objects based on their overall shape. As children mature, they may create basic categories that later disappear, such as "objects with wheels". Researchers are interested in how children learn to categorize objects, and whether this is based on shape, function, or other perceptual details.
Gestalt psychology is a theory of mind that has been applied to various aspects of human thought, action, and perception. Gestalt theorists aim to understand visual perception in terms of the underlying processes that help us make sense of the world. One of the key principles of Gestalt psychology is invariance, which explains how we perceive basic shapes as identical despite transformations such as rotation, movement, and size alteration. This principle is important for recognizing faces, for example. Another principle is the tendency to simplify complexity, known as Pragnanz.

Mat, hat, cat
The grouping of objects or concepts into categories is a fundamental aspect of human cognition. It allows us to make sense of the world by organizing our perceptions and facilitating our interactions with the environment. This process of categorization is influenced by various factors, including the similarities between objects, their functional or semantic relationships, and the context in which they are presented.
When considering the grouping "mat, hat, cat," we can examine the perceptual and conceptual connections that unite these three words. Firstly, from a perceptual standpoint, 'mat,' 'hat,' and 'cat' share a similar sound structure. They all begin with the consonant blend "m," "h," and "c," respectively, followed by the vowel "a," creating a rhythmic consistency. This phonetic similarity can contribute to their grouping as they evoke a harmonious auditory pattern.
Additionally, the three words possess a visual connection through the repetition of the letter "a" in their spellings. The shared letter creates a sense of continuity and cohesion, making it easier for the brain to process and group them together. This principle, known as the Gestalt principle of continuity, suggests that we tend to perceive elements that follow a continuous pattern as belonging together.
From a conceptual standpoint, the words "mat," "hat," and "cat" can be associated with domesticity and comfort. A mat often refers to a comfortable rug or carpet, a hat can be a cozy accessory, and a cat is a domesticated animal often associated with companionship. This shared theme of comfort and familiarity could be another factor that contributes to their grouping.
Furthermore, the three words can be linked through semantic associations. A mat could be a place for a cat to rest or play, and a hat could be an accessory for a person owning or interacting with a cat. These semantic connections create a network of associations that reinforce the grouping of "mat," "hat," and "cat" as conceptually related.
It's important to note that the grouping of these words may also be influenced by individual experiences and cultural contexts. For instance, a person who owns a cat and enjoys spending time on a cozy mat while wearing a favorite hat may have an even stronger association between these concepts.
In summary, the grouping of "mat, hat, cat" can be understood through their perceptual similarities in sound and spelling, as well as conceptual links related to domesticity, comfort, and semantic associations. This example illustrates how our minds create categories to make sense of the world, highlighting the dynamic nature of human perception and cognition.

Sofa, grandfather clock, table
The grouping of objects into categories is a fundamental aspect of human cognition. This process of categorisation is influenced by various factors, including perceptual similarities, functional similarities, and hierarchical relationships.
When considering the objects "sofa, grandfather clock, and table", the question of whether they constitute members of the same perceptual category arises. A perceptual category refers to the grouping of items based on visual or sensory similarities. In this case, the three objects may not be immediately apparent as belonging to the same perceptual category due to their distinct visual characteristics. Sofas, grandfather clocks, and tables differ in shape, size, and function, making them seem unrelated at first glance.
However, upon closer examination, we can identify some underlying perceptual similarities. All three objects are typically found within indoor living spaces, such as foyers, living rooms, or bedrooms. They are also generally associated with the concept of comfort and relaxation, as they contribute to the overall ambiance and functionality of these spaces. Additionally, sofas, grandfather clocks, and tables can be perceived as objects that are typically stationary and placed on the floor, as opposed to being hung on walls or placed on shelves.
Furthermore, from a design perspective, these objects may share certain aesthetic qualities, such as colour, texture, or style, depending on the specific pieces in question. For example, a wooden sofa, table, and grandfather clock with similar wood grains and hues could be considered members of the same perceptual category based on their shared visual attributes.
In conclusion, while sofas, grandfather clocks, and tables serve different functions and possess unique characteristics, they can be perceived as members of the same perceptual category when considering their shared contextual and aesthetic qualities. The categorisation of these objects is a complex process influenced by individual perceptions, cultural contexts, and the specific characteristics of the items in question.

iPad, picture frame, book
The grouping of objects into categories is a fundamental aspect of human perception and cognition. This process of categorisation is influenced by various factors, including the object's perceptual features, functional similarities, and abstract concepts.
When considering the objects "iPad, picture frame, and book," one might initially perceive them as distinct entities serving different purposes. However, upon closer examination, these objects do share some commonalities that could place them in the same perceptual category. All three objects serve as tools for consuming visual content, whether it be through reading (book), viewing images or videos (iPad and picture frame), or a combination of both (iPad and book). Additionally, advancements in technology have blurred the lines between these objects, as iPads can now display digital books, and picture frames can be digital, connecting to iCloud and displaying images from a smartphone.
From a design perspective, the iPad, picture frame, and book can be perceived as sharing certain aesthetic qualities. For example, the iPad and picture frame may have similar rectangular shapes, while a book can also be rectangular when closed. The iPad and book both possess a flat surface for displaying content, and the picture frame serves a similar function of presenting visual content within a confined space.
Furthermore, the iPad, picture frame, and book can be considered in terms of their functional similarities. All three objects facilitate the consumption of visual information, albeit in different formats. The iPad and book provide textual and visual content, while the picture frame focuses solely on visual content. However, with the increasing popularity of digital books, the iPad may be predominantly used for reading, further blurring the boundaries between these objects.
In conclusion, while the iPad, picture frame, and book may initially appear distinct, they share functional and aesthetic similarities that could place them in the same perceptual category. The convergence of technology and traditional mediums has contributed to this grouping, challenging our initial perceptions and highlighting the dynamic nature of categorisation.

Perceptual vs language-mediated categorisation
The process of categorisation involves grouping similar elements, recognising patterns, and simplifying complex images. Categorisation can be perceptual or language-mediated.
Perceptual Categorisation
Perceptual categorisation involves the grouping of objects based on their perceptual features. For example, infants as young as two months can form perceptual categories for many objects at both the basic (e.g. dogs, cats, chairs, couches) and global levels (e.g. animals, vehicles, furniture). Perceptual categories can also be coherent, with members sharing multiple overlapping features, such as the category of "cats".
Language-Mediated Categorisation
Language-mediated categorisation, on the other hand, involves the use of labels to group objects. Labels can act on the perceptual similarity structure and warp the similarity space, leading to objects with the same label being perceived as more similar. This transition from perceptual categorisation to language-mediated categorisation occurs during the first year of life, as object knowledge develops and representations become shaped by labels, leading to the development of conceptual knowledge.
Gestalt Principles
The Gestalt Principles are a set of laws created by German psychologists Max Wertheimer, Kurt Koffka, and Wolfgang Kohler in the 1920s to understand how people make sense of confusing visual and auditory stimuli. These principles include figure/ground relationships, similarity, proximity, and continuity. For example, the principle of invariance explains how we perceive basic shapes as identical despite transformations such as rotation, movement, and size alteration.
Categorical Perception
Categorical perception (CP) refers to the effect of language on perception. While there is evidence of universal perception across different cultures and languages, such as the perception of colours, there are also differences influenced by cultural and linguistic factors. For instance, the left hemisphere of the brain, where linguistic categories are stored for most people, affects categorical perception in the right visual field.
