【研究表明,狗可能不像人们认为的那样聪明】据每日邮报报道,一项新的研究发现,狗并不像许多人认为的那样聪明。来自埃克塞特和坎特伯雷大学的心理学家研究了狗与其他动物相比的认知能力。他们得出的结论是,犬科动物的智力并不比其他物种高,并且在理解它们周围的物体方面并不是特别擅长。还有猪在通过气味识别人类的测试中,其表现与狗一样好。

 

Ruff news! Dogs are 'no more intelligent' than cats say experts (no matter how much of a clever boy you think they are)

  • Findings revealed by psychologists from Exeter and Canterbury University
  • Study says that dogs may not be as smart as people perceive them to be
  • Researchers explored sensory,physical, spatial cognition and social cognition
  • Dogs no better than animals like cats and horses at associative learning
  • Their sense of smell is excellent but pigs 'may have better olfactory abilities

It may seem from a dog's friendly demeanour and ability to perform tricks that they are smarter than most animals but a new study suggests this is not the case.

Psychologists from Exeter and Canterbury University examined the cognitive abilities of 'man's best friend' when compared with other animals - including cats.

Experts concluded that canines do not possess particularly higher intelligence than their feline rivals, as well as a number of other creatures.

Researchers used data on observations of the behaviour of dogs, cats, wolves and chimpanzees to see if pooches possessed any specific special skills.

They found that dog's mental faculties are not exceptional compared to other species and were even bested in many categories.

The study, led by Professor Stephen Lea and Dr Britta Osthaus, was published in the December issue of scientific journal Learning and Behaviour.

They compared canine cognition to other carnivores, social hunters and domestic animals.

Various aspects of a dog's intelligence were analysed, including sensory, physical, spatial and social cognition as well as self-awareness.

The team used a series of tests to assess how different animals reacted.

Examples included the ability to follow human pointing, which indicated that dolphins, seals and pigs were top of the class in this respect.

When it came to pulling strings to release food, wolves, cats and racoons were more effective at learning the ropes than dogs.

Cats were found to be good at locating hidden objects, though relying primarily on egocentric cues. Physical cognition is not a domain in which dogs excel, and their performance is at least equalled by other members of all three of our comparison groups (stock image)

Professor Lea and Dr Osthaus said that dogs appear to be no better than other animals at associative learning.

They gave an example of when they're being trained to respond to social cues by an owner.

When it came to physical cognition, how dogs understand objects around them, they were 'at least average'.

Their social cognition was above average, especially when they are taking cues from humans.

'Dogs have an impressive ability to use other animals’ behaviour (particularly the behaviour of humans) as a cue,' they said.

In spatial tasks, dogs have shown good performance, but the same is true of other species

They referred to studies that dogs have been used in countless behavioural and psychological experiments over the years due to their status as 'model organisms'.

They gave an example of Ivan Pavlov's 1927 study on the way in which dogs salivate when presented with food.

They were simply choosing to use canines in the experiments as a matter of convenience.

The scientists explained that early research didn't compare the cognitive abilities of dogs to other animals.

While many may think that dogs have the best sense of smell in the animal kingdom, the researchers found that pigs ' might even be better than the dog's'.

Professor Lea and Dr Osthaus found that horses were 'just as able' to communicate with humans just as well as their canine peers
