The Laughter Project is led by Ceci, together with Sarah and Prof. Sophie Scott. We focus on the understanding and production of laughter in autistic and non-autistic adults.

Laughter is primarily viewed as positive emotional vocalization associated with humour and amusement, e.g. you cannot help yourself laughing while watching funny videos on Tiktok/YouTube. However, imagine a situation like this: your friend is telling a joke, you do not get the joke BUT you laugh with your friends. Indeed, laughter is commonly used as a communicative tool, you laugh because you like your friend and you are willing to join their laughter. By carrying out social functions, such as showing politeness, agreement, and affiliation in daily interaction, laughter has a great benefit for our social well-being as a remarkable social signal.

Autistic people experience difficulty in social communication in everyday life. As a non-verbal communicative tool, laughter plays an important role in establishing and maintaining social bonds. Investigating how the self-reported experience, perception and production of laughter differ between autistic and non-autistic people could let us better understand the underlying neurocognitive mechanism of laughter and the developmental trajectory of social-emotional vocalisation and its function in social interaction.

The laughter project implements behavioural testing and neuroimaging approaches:

• Laughter as a Social Behaviour
• Laughter Questionnaire: A Cross-Cultural Investigation;
• Explicit Processing of Laughter between Autistic and Non-Autistic People (since 2015);
• Laughter Production among Friends & Strangers, Autistic and Non-Autistic: a Multi-level Dyadic Study
• The Implicit Processing of Laughter
• Modulatory Effect on Humour Stimuli: a series of Behavioural Studies (Read more: Modulation of humor ratings of bad jokes by other people’s laughter);
• Understanding the processing of social communication in adults with and without autism: a fMRI study;

We hope this project could contribute to improving mutual understanding between autistic and non-autistic people and also improve the support available to people who experience these social-communication difficulties.

The laughter project is funded by the Royal Society, the Academy of Medical Sciences and the China Scholarship Council. Studies have been approved by the UCL Research Ethics Committee (ethics@ucl.ac.uk).
