The study found that monkeys can localize stimuli they do not perceive, similar to humans, who can also locate and side-step objects in their peripheral vision. Monkeys performed tasks accurately when stimuli were unmasked, but still localized targets at masking levels for which they reported no target had been presented.
According to Swedish Research Council study, humans have musical talent due to synchronized group movement, which enhances sound perception in nature. This behavior has survival value, producing dopamine, leading to rhythmic movements and eventually music.
Researchers found dogs can reproduce familiar and novel actions after different delays, even when distracted. The ability to imitate human actions suggests the presence of a specific type of long-term memory in dogs.
A Michigan State University team used a model system to show that predator confusion can evolve swarming behavior in prey, allowing groups to defend themselves against larger predators. This discovery provides insights into the evolution of intelligence and how it developed in nature.
Researchers at the University of Iowa found that pigeons can learn and solve complex string tasks using computerized touch screens. The birds demonstrated accuracy rates of up to 90% in solving various string configurations.
Researchers found that bats react strongly to all contact calls, regardless of familiarity. However, when presented with a call from a known bat multiple times, they showed a stronger response to other partners from their social group. This suggests individual evaluation of the voice, indicating recognition of conspecifics by sound.
A recent study by Dr. Dominique Autier-Dérian and colleagues found that dogs can form a visual category of dog faces and group pictures of different breeds into a single category. This ability allows dogs to recognize their own species visually, despite the large morphological variability within the dog species.
In a study of wild field crickets, males are found to protect females from predators, increasing their chances of survival. In exchange, paired males sire more offspring with each partner, suggesting that this 'chivalry' may have evolutionary benefits. The findings challenge traditional interpretations of male guarding behavior.
Researchers investigated problem-solving abilities and innovative capacities of kea and New Caledonian crow. The studies revealed that both species employ various tools to achieve food rewards, with the kea mastering compact object tools and the crow using elongated objects like sticks to probe for grubs.
A study by the American Academy of Neurology found that speaking multiple languages can protect against memory decline in seniors. Researchers discovered that individuals who spoke four or more languages were significantly less likely to experience cognitive problems compared to those with limited language proficiency.
A new study reveals that orangutan gestures carry specific intentional meanings and are made with the expectation of behavioral responses. The researchers identified 64 gesture types, 40 of which were used predictably to achieve six social goals, including initiating interactions and requesting objects.
Non-human animals, including gorillas and chimpanzees, exhibit knowledge about what they have seen in experiments. The apes reduce checking before choosing when provided with auditory information about the food's location, suggesting metacognitive abilities.
A new study published in Current Biology reveals that children from different cultures articulate spatial relations differently, with German kids using egocentric terms and Akhoe Hai||om kids using allocentric notions. This finding highlights the diversity of human cognition across cultures.
Scientists at Queen Mary University of London found that insect brains are capable of intelligent behaviors like counting and categorizing, challenging the idea that larger brains are more intelligent. Research suggests that many size differences in brain size only exist in specific regions and may not lead to increased complexity.
A new study demonstrates that rooks can solve complex problems using tools, including raising water levels to reach a floating worm. The birds' ability to estimate the number of stones needed and adapt to different stone sizes shows remarkable intelligence.
Researchers found that rooks can learn to use stones to raise the level of water, bringing a floating worm within reach. The birds demonstrated impressive accuracy and problem-solving skills.
