  • Piglets prefer new toys, behavior study shows
    on June 21, 2017 at 4:53 pm

    We can't help but be tempted by new things. We see it in a child's eyes when she opens a new toy, and feel it every time a new version of the iPhone is released. It turns out our preference for shiny, new things is pretty universal throughout the animal kingdom. Yes, even piglets prefer new toys. […]

  • Cockatoos keep their tools safe
    on May 16, 2017 at 1:11 pm

    Only a few animal species such as New Caledonian crows or some primates have so far been found to habitually use tools. Even fewer can manufacture their own tools. Nevertheless, the Goffin's cockatoo, an Indonesian parrot, exhibit both abilities while seemingly lacking a genetic adaptation for tool use. Researchers have now shown yet another tool-related ability in these clever parrots. […]

  • How dogs interact with others plays a role in decision-making
    on April 24, 2017 at 6:22 pm

    Dynamics between familiar dogs may influence their likelihood of learning from each other, new research shows. How dogs interact with others plays a big role in how they respond under conditions that require quick thinking. […]

  • Elephants' 'body awareness' adds to increasing evidence of their intelligence
    on April 12, 2017 at 12:53 pm

    Asian elephants are able to recognize their bodies as obstacles to success in problem-solving, further strengthening evidence of their intelligence and self-awareness, according to a new study. […]

  • You spy with your little eye, dogs can adopt the perspective of humans
    on April 7, 2017 at 1:18 pm

    Humans are able to interpret the behavior of others by attributing mental states to them (and to themselves). By adopting the perspectives of other persons, they can assume their emotions, needs and intentions and react accordingly. In the animal kingdom, the ability to attribute mental states (Theory of Mind) is a highly contentious issue. Cognitive biologists could demonstrate with a new test procedure that dogs are not only able to identify whether a human has an eye on a food source and, therefore, knows where the food has been hidden. They can also apply this knowledge in order to correctly interpret cues by humans and find food they cannot see themselves. […]

  • Do smart songbirds always get the girl?
    on April 3, 2017 at 1:13 pm

    Compelling evidence shows females prefer mates with better cognitive abilities in a number of animals and even humans. For male songbirds, their ability to sing complex songs has been suggested to signal cognitive ability and is vital for attracting females as well as repelling rival males. What's not clear is how female songbirds can judge the cognitive abilities of potential mates, which is a necessary first step if smarter mates are preferred over their not-as-smart counterparts. […]

  • Brain scans of service-dog trainees help sort weaker recruits from the pack
    on March 7, 2017 at 3:04 pm

    Brain scans of canine candidates to assist people with disabilities can help predict which dogs will fail a rigorous service training program, a study by finds. The study found that fMRI boosted the ability to identify dogs that would ultimately fail service-dog training to 67 percent, up from about 47 percent without the use of fMRI. […]

  • Horse-riding can improve children's cognitive ability
    on March 2, 2017 at 4:58 pm

    Recent research shows that the effects of vibrations produced by horses during horse-riding lead to the activation of the sympathetic nervous system, which improves learning in children. […]

  • Dogs, toddlers show similarities in social intelligence
    on February 27, 2017 at 5:51 pm

    Researchers have found that dogs and 2-year-old children show similar patterns in social intelligence, much more so than human children and one of their closest relatives: chimpanzees. The research could help scientists better understand how humans evolved socially. […]

  • Delaying marijuana smoking to age 17 cuts risks to teens' brains, new study suggests
    on January 26, 2017 at 2:46 am

    Adolescents who smoke marijuana as early as 14 do worse by 20 points on some cognitive tests and drop out of school at a higher rate than non-smokers. But if they hold off until age 17, they're less at risk. […]

  • Macaques, like humans, know how well they can recall memories
    on January 12, 2017 at 7:12 pm

    Researchers have pinpointed a brain region monkeys use to evaluate their ability to recall memories. To date, this metamemory process, which requires a higher level of self-reflection about our own cognition, was thought by some to be unique to humans, though this research suggests otherwise. […]

  • Think chicken: Think intelligent, caring and complex
    on January 3, 2017 at 2:19 pm

    Chickens are not as clueless or 'bird-brained' as people believe them to be. They have distinct personalities and can outmaneuver one another. They know their place in the pecking order, and can reason by deduction, which is an ability that humans develop by the age of seven. Chicken intelligence is therefore unnecessarily underestimated and overshadowed by other avian groups. […]

  • When horses are in trouble they ask humans for help
    on December 15, 2016 at 1:08 pm

    When horses face unsolvable problems, they use visual and tactile signals to get human attention and ask for help, a new study has demonstrated. The study also suggests that horses alter their communicative behavior based on humans' knowledge of the situation. […]

  • Nutrition linked to brain health and intelligence in older adults
    on December 13, 2016 at 4:31 pm

    A study of older adults links consumption of a pigment found in leafy greens to the preservation of 'crystallized intelligence,' the ability to use the skills and knowledge one has acquired over a lifetime. […]

  • Learning makes animals intelligent
    on November 30, 2016 at 1:50 pm

    The fact that animals can use tools, have self-control and certain expectations of life can be explained with the help of a new learning model for animal behavior. Researchers have combined knowledge from the fields of artificial intelligence, ethology and the psychology of learning to solve several problems concerning the behavior and intelligence of animals. […]

  • Your dog remembers what you did
    on November 23, 2016 at 7:15 pm

    People have a remarkable ability to remember and recall events from the past, even when those events didn't hold any particular importance at the time they occurred. Now, researchers have evidence that dogs have that kind of "episodic memory" too. […]

  • Psychological science explores the minds of dogs
    on October 24, 2016 at 9:15 pm

    Dogs are one of the most common household pets in the world, so it's curious that we know relatively little about their cognitive abilities when we know so much about the abilities of other animals, from primates to cetaceans. Over the last couple decades, researchers have been aiming to bridge this gap in scientific knowledge, investigating how our canine companions behave and what they know and why. An entire special issue of a journal is this month dedicated to exploring all that psychological scientists have learned about dog behavior and cognition in recent years. […]

  • String pulling bees provide insight into spread of culture
    on October 4, 2016 at 6:14 pm

    Bumblebees can learn to pull strings for food and pass on the ability to a colony, according to new research. […]

  • Two Barbados bird species enter the select club of string-pullers
    on August 17, 2016 at 6:25 pm

    The Barbados bullfinch and Carib grackle can pass the popular animal cognition test of string-pulling, but this ability may be unrelated to performance on six other cognitive tests, according a study. […]

  • Newborn ducklings can acquire notions of 'same' and 'different'
    on July 14, 2016 at 7:18 pm

    Scientists have shown that newly hatched ducklings can readily acquire the concepts of 'same' and 'different' -- an ability previously known only in highly intelligent animals such as apes, crows and parrots. […]

  • Could goats become our new best friend?
    on July 6, 2016 at 12:31 am

    Goats have the capacity to communicate with people like other domesticated animals, such as dogs and horses, according to scientists. The researchers hope the study will lead to a better understanding of how skilled livestock are in their aptitude to solve problems and interact with humans based on their cognitive abilities -- and to an improvement in animal welfare in general. […]

  • Bird brain? Ounce for ounce birds have significantly more neurons in their brains than mammals or...
    on June 13, 2016 at 7:34 pm

    The first study to systematically measure the number of neurons in the brains of birds has found that they have significantly more neurons packed into their small brains than are stuffed into mammalian and even primate brains of the same mass. […]

  • The primate brain is 'pre-adapted' to face potentially any situation
    on June 10, 2016 at 9:35 pm

    Scientists have shown how the brain anticipates all of the new situations that it may encounter in a lifetime by creating a special kind of neural network that is 'pre-adapted' to face any eventuality. […]

  • Brain cells divide the work to recognize bodies
    on April 28, 2016 at 1:44 pm

    Specific regions of the brain are specialized in recognizing bodies of animals and human beings. By measuring the electrical activity per cell, scientists have shown that the individual brain cells in these areas do different things. Their response to specific contours or body shapes is very selective. […]

  • A single-celled organism capable of learning
    on April 27, 2016 at 12:15 pm

    For the first time, scientists have demonstrated that an organism devoid of a nervous system is capable of learning. Biologists have succeeded in showing that a single-celled organism, the protist, is capable of a type of learning called habituation. This discovery throws light on the origins of learning ability during evolution, even before the appearance of a nervous system and brain. It may also raise questions as to the learning capacities of other extremely simple organisms such as viruses and bacteria. […]

  • Despite their small brains, ravens and crows may be just as clever as chimps, research suggests
    on April 26, 2016 at 2:15 pm

    A new study suggests that ravens can be as clever as chimpanzees, despite having much smaller brains, indicating that rather than the size of the brain, the neuronal density and the structure of the birds' brains play an important role in terms of their intelligence. […]

  • Can some birds be just as smart as apes?
    on March 3, 2016 at 1:46 pm

    At first glance, the brains of birds and mammals show many significant differences. In spite of that, the cognitive skills of some groups of birds match those of apes, according to a new article. […]

  • Brain boost: Research to improve memory through electricity?
    on February 29, 2016 at 8:29 pm

    In a breakthrough study that could improve how people learn and retain information, researchers significantly boosted the memory and mental performance of laboratory mice through electrical stimulation. […]

  • Human children and wild great apes share their tool use cognition
    on February 24, 2016 at 12:01 pm

    Young children will spontaneously invent tool behaviors to solve novel problems, without the help of adults, much as non-human great apes have been observed to do. The findings are contrary to the popular belief that basic tool use in humans requires social learning. […]

  • Inhibitory control may affect physical problem solving in pet dogs
    on February 10, 2016 at 9:57 pm

    Inhibitory control may be an indicator of a dog's ability to solve a problem, according to a new study. […]
