Woo new paper! Cross-cultural investigation into maternal responses to infant distress

How babies are soothed may be more important than how quickly, which vary cross-culturally

New paper alert!

Bonobos are often cited as the 'most empathic ape' yet a comparison to their chimp cousins has never been done. So we directly compared their consolation tendencies

We found big overlaps between the two species plus considerable within-species variation

He also defied the odds in many ways- including achieving incredible weight loss in his latter years and surviving into his 40s, an age far older than most male bonobos reach in captivity

The loss of a legend- Kanzi, the language-competent bonobo, has died age 44.
Kanzi was exceptional in so many ways and offered us profound insights into the linguistic & cognitive capacities of great apes. He has taught us so much and will be hugely missed.

Inside the sex lives of chimpanzees: like humans and other species, it’s about much more than just reproduction

New piece in @ConversationUK about our new @royalsociety research study on the social role of sex in chimps and bonobos. @durhampsych.bsky.social

New paper alert! Sex and strife in our closest ape relatives

Our paper in @RSocPublishing shows that bonobos and chimpanzees overlap in their use of sex during social tension

We found that nose temperature changes were strongest in response to crying (& laughing) vs artificial aversive sounds and neutral babbling. Behaviourally, infants also reacted more strongly to crying. Our results suggest that infants experience emotional contagion in response to others' distress.
