【狗狗的表情你真的懂吗?】

【狗狗的表情你真的懂吗?】来自赫尔辛基大学和阿尔托大学的一项研究发现,人类善于识别狗的威胁表情,而对于狗的愉快表情则识别得不太明显。研究人员称,这可能由于一种倾向,通常认为自己同类的面部更愉快。研究表明,人类以类似于人类面部表情的方式来解读狗的面部表情,且同情心使人们能够更快更强烈地评估狗的面部表情。Kujala博士表示,同情加速和加强了狗的面部表情的评估可能因为面部是人类的生物学重要刺激,但确定这种评估的准确性目前是不可靠的,人们可能会过度解释狗的面部表情。

Dog lovers process canine faces as if they were human

  • People who are more empathetic can assess facial expressions more quickly 
  • Empathetic people also assess dogs' facial expressions more intensely 
  • But it's possible that they over-interpret the expressions of dogs
  • Humans are better at recognizing threatening expressions in dogs than in humans, but rated happy facial expressions more intensely in humans

Researchers have found that empathetic people interpret the facial expressions of dogs more intensely.

The research suggests that humans interpret dog facial expressions in a similar way to human facial expressions.

Empathy also makes people assess dogs' emotional facial expressions more rapidly.

The research, based at the University of Helsinki and Aalto university, found that humans are good at recognizing the threatening facial expressions of dogs and considered them much more intense than similar threatening human expressions.

However, humans rated happy facial expressions less intensely in dogs than they did in other humans.

The researchers said that this may be because there is a tendency to consider the faces of one's own species as generally more pleasant.

But people experienced with dogs, such as dog trainers, were able to assess happy facial expressions in dogs more easily.

Dr Miiamaaria Kujala, a post-doctoral researcher at the University of Helsinki, said: 'Empathy affected assessments of dogs' facial expressions even more than previous experience of dogs, probably because the face is a biologically important stimulus for humans.

'Our earlier studies have showed, however, that when considering the entire body language of dogs, previous experience of dogs increases in importance.'

Dr Kujala also said that people may be over-interpreting the facial expressions of dogs.

'Empathy speeds up and intensifies the assessment of dogs' facial expressions, but defining the accuracy of such assessments is currently unreliable.'

To conduct the study, the researchers asked 34 participants to rate six basic emotions (happiness, sadness, surprise, disgust, fear, and anger/aggressiveness) from images of human and dog faces with pleasant, neutral and threatening facial expressions.

The researchers also measured how the participants' personality traits, empathy levels and experience of dog behavior affected their assessments of dog and human facial expressions.

Humans classified dog facial expressions very similarly to human expressions, with the exception of happy facial expressions.

Dogs also clearly recognize the threatening expressions of both humans and other dogs.
