Animal cognition is the study of the mental processes and abilities of animals, including perception, learning, memory, problem-solving, communication, and decision-making. Researchers in this field examine the cognitive abilities of a wide range of animal species, from insects and fish to birds and mammals, in order to better understand the ways in which animals think and interact with their environments. This research contributes to our knowledge of the complexity and diversity of cognitive abilities across the animal kingdom and can also shed light on the evolution of intelligence and consciousness.
