Researchers tested 17 adult dogs of various breeds to see whether they could recognize emotional expressions in the faces and voices of humans and other dogs - an ability that’s considered a higher cognitive talent because two different senses are involved. Each dog took part in two test sessions with 10 trials. One by one, they stood facing two screens on which the researchers projected photos of unfamiliar but happy/playful human or dog faces versus the same faces with angry/aggressive expressions (as in the photo above). At the same time, the scientists played a single vocalization - either a dog bark, ...

A new psychology study suggests that women are better than men at reading people's thoughts and emotions, just by looking at the eyes.

Researchers from around the globe tested the way genes influence a person's cognitive empathy; their ability to accurately recognise another person's emotional state. 90,000 people were shown different photographs of people's eyes and asked to determine their mood. Results showed that women more consistently picked the correct feeling when the participants had to select what emotion they perceived when shown a visual of a person's eyes.

This is the first big study on cognitive empathy and its relationship to gender. The international research team has also identified a potential genetic region that influences ...
