Throughout history, we’ve observed the abilities of different species, from the dance of bees that communicate the location of nectar-rich flowers, to the amazing ability of crows to solve complex problems. These behaviors have led scientists to rethink the function of animal cognition: How similar are animals’ minds to our own? Can animals think, reason, or even have emotions?
This article explores some facts about animal cognition, highlighting some examples. As we expand our knowledge about the mental capacities of animals, we are faced with questions about our relationship with them and our place in the animal kingdom.
What is animal cognition?
It is a field of research that focuses on how animals perceive their environment and acquire, process, store, and use information to make decisions and solve problems. Animal cognition encompasses memory, learning, perception, decision-making, and problem-solving. It also includes tool use, communication, and the ability to recognize other individuals or even themselves.
Animal cognition is also interested in understanding how different species have developed certain abilities based on their evolutionary and environmental needs. This includes investigating how the brain structure and sensory systems of animals are adapted to process information in unique ways and how this influences their behavior.
The study of animal cognition also has important implications for animal ethics, conservation, evolutionary biology, and comparative psychology. It challenges traditional notions about intelligence and consciousness and leads us to reconsider our relationships with other species.
How is cognition manifested in animal behavior?
Cognition in animal behavior involves an integration of various mental skills that allow animals to interact effectively with their environment and with other living beings. These cognitive processes are essential for survival, as they help animals adapt to changes in their environment, find food, avoid predators, and reproduce successfully. In terms of animal behavior, cognition manifests itself through a variety of skills and activities, which we will discuss below.
Perception and sensory processing
This means how animals interpret sensory information from the world around them, such as vision, smell, hearing, and touch. For example, bats use echolocation to navigate in the dark, and bees can see colors in the ultraviolet spectrum.
Learning and memory
Another way that cognition manifests itself in animal behavior is through their ability to acquire new skills or knowledge through experience. That information is then retained over time. This can include associative learning, such as a dog learning to associate the sound of a doorbell with mealtime. Or spatial memory, such as that used by squirrels to remember where they buried their nuts.
decision making
The processes by which animals choose between different options are based on an assessment of risks, benefits, and past experiences. For example, birds must decide which food is safest or most nutritious based on the information available.
Troubleshooting
Animals develop problem-solving skills to confront and overcome obstacles or challenges that require flexible thinking and creativity. Crows and primates are known for their complex problem-solving skills, such as using tools to obtain inaccessible food.
Communication and signaling
How animals transmit and receive information to each other, whether through sounds, body movements, chemical signals, or colors. Dolphins, for example, use a complex system of vocalizations to communicate with each other, while bees perform a “dance” to indicate the location of nectar sources to their companions.
Recognition and social cognition
The ability of animals to recognize other individuals, whether of their own or other species and to understand social relationships and hierarchies. For example, elephants can recognize other elephants even after long periods of separation, and primates can understand the social alliances and intentions of other members of their group.
Examples of animal cognition
Animal cognition encompasses a wide range of cognitive abilities that show how different species perceive, learn, remember, and solve problems. Here are some fascinating examples of animal cognition:
Tool use in crows and primates
New Caledonian Crows: These crows are known for their tool-using abilities. They can bend twigs into hook shapes to remove insects from holes in wood. In laboratory experiments, crows have been observed to be able to use multiple tools in sequence to solve complex problems. This demonstrates advanced planning and reasoning skills.
Chimpanzees: In the wild, chimpanzees use sticks to dig termites out of mounds, leaves to collect water, and stones as hammers to crack nuts. This behavior shows an understanding of causality and the manipulation of objects to achieve a specific goal.
Spatial memory in squirrels and elephants
Squirrels: Squirrels are known for burying food to store and retrieve later. They have exceptional spatial memory that allows them to remember the location of hundreds of food caches, even after months.
Elephants: Elephants have an impressive memory, especially regarding geography and water sources. They can remember the location of water sources they haven’t visited for years and direct their herds across vast distances during periods of drought.
Problem-solving in octopuses and dolphins
Octopuses: Octopuses are known for their intelligence and problem-solving abilities. In experiments, they have been observed opening jars to obtain food found inside. Their ability to manipulate objects and solve complex problems shows advanced cognition in an invertebrate.
Dolphins: Dolphins show advanced problem-solving skills and understanding abstract concepts. They can understand complex commands, perform sequential tasks, and have demonstrated self-control skills.

Communication and language in bees and parrots
Bees: Honey bees use a complex form of communication known as a “waggle dance” to inform other bees of the location, distance, and quality of nectar sources. This communication requires the interpretation of visual and olfactory cues, as well as spatial understanding.
African Grey Parrots: This type of parrot is famous for its ability to mimic sounds and understand language concepts. The parrot Alex, in particular, demonstrated the ability to understand concepts such as numbers, colors, shapes, and differences. This suggests a form of cognition similar to human language.
Facial recognition and empathy in dogs and primates
Dogs: Dogs can recognize human emotions through facial expressions and tone of voice. They can differentiate between happy and angry faces, and adjust their behavior accordingly, indicating empathy and emotional recognition.
Primates: Many primates, including chimpanzees and bonobos, display advanced facial recognition skills. They can recognize individual members of their group, remember past interactions, and adjust their social behavior accordingly. Additionally, they have shown empathic behaviors, such as comforting other individuals in distress.
These examples illustrate the rich variety of cognitive abilities present in the animal kingdom, demonstrating that intelligence and cognition are not unique to humans, but are distributed across many species in diverse and adaptive ways.
