Today's podcast - released on none other than International Podcast Day...yes, it's a a follow up interview with Evan Jordan of Oklahoma State University.

If you are a new listener to the Laughter Research Podcast, you might like to check out the previous interview HERE. Evan has been the lead investigator on a study which has been examining various aspects of infant development. Needless to say, of particular interest to me is the laughter aspect of the research.

Evan sought to uncover the extent of contagiousness of positive emotions in infants, with a particular focus upon laughter. You might be very surprised by the findings, but you'll have to listen in to find out more on that.

We discuss the challenges and joys of working with infants in research and we discuss the future directions for research in the arena of contagious laughter. We also ponder the possibility of Evan earning an Oscar for her thank you 'Shout Out' at the end of the podcast.

During the conversation I mention an excellent book by Robert Provine. Check it out on Amazon. It's well worth picking up.


We also mention the innate aspect of laughter and discuss how infants who are born deaf and blind will develop laughter around the same stage of development as typical children.

A couple of interesting papers related to this topic:

No. 1 relates to the acoustic profile of laughter in congenitally deaf people:

In this paper the authors attribute some acoustic variation between the laughter of hearing people and deaf people as being "Due to a combination of the physiological and social factors that routinely affect profoundly deaf individuals, including low overall rates of vocal fold use and pressure from the hearing world to suppress spontaneous vocalizations." - In other words, invisible social rules influence how and when people laugh.

"Deaf individuals report experiencing social pressure to suppress spontaneous vocalizations, as these can be uncomfortably loud for the hearing (Leder and Spitzer, 1993)."

Makagon, M. M., Funayama, E. S., & Owren, M. J. (2008). An acoustic analysis of laughter produced by congenitally deaf and normally hearing college students. The Journal of the Acoustical Society of America, 124(1), 472–483.

No. 2 relates to the use of laughter as a form of punctuation in deaf people using sign language:

Provine, R. R., & Emmorey, K. (2006). Laughter Among Deaf Signers. Journal of Deaf Studies and Deaf Education, 11(4), 403–409.

This paper is particularly relevant as it shows us how laughter is fluidly incorporated into more complex cognitive interactions and it indicates that the appropriate timing of 'conversational' laughter is a learned skill.

My guest in podcast episode #15 is Merv Neal. Merv has a lengthy background in business, but a life threatening challenge to his health instigated a transformation in his approach to life. His goals switched from making money to improving the health of others and himself through the use of laughter.

In this episode we explore Merv’s journey from Merv the businessman to Merv the Laughing Man and we learn about Merv’s involvement in medical and psychological research which involved laughter therapy. We also talk about the attitude to laughter in the business world and how Merv overcomes the challenge of turning serious business people from positions of adamant resistance to willing participation in his laughter sessions.

Today I speak with Evan Jordan of Oklahoma State University in the U.S. about her research in to the contagiousness of positive emotions in infants, through the use of infant laughter as a stimulus. 

If you would like to hear about how psychologists get babies to laugh and why it is that they want them to laugh, then you'll find this episode to be fascinating.

Professor Sophie Scott is the deputy director for the Institute of Cognitive Neuroscience in UCL (University College London).

While the main focus of her research is the neurobiology of speech perception, her work also includes the study of the neuroscience of laughter. She also dabbles in stand-up comedy.

Sophie believes that laughter is one of the most complex and nuanced things that we do. She feels that we should take laughter more seriously, both in terms of science, but also in terms of our experience, because very often, our laughter is telling us a lot more about how we feel about people we are laughing with than we might typically acknowledge to ourselves. 

In this episode we discuss the evolutionary basis for laughter, social differences in comedy appreciation, the neurology & physiology of laughter, how science is beginning to take laughter more seriously and a host of other topics in between.

The main focus of my conversation with Prof. Billig was the topic of his book Laughter and Ridicule: Towards a Social Critique of Humour (Published in association with Theory, Culture & Society) in which he explores the important role which ridicule and laughter play in shaping social behaviours. In his book, Michael takes a critical approach to the topics of laughter and humour and he questions the common assumptions which are made, in particular by popular and academic psychology.

Laughter Yoga is a very interesting phenomenon from a scientific perspective, because it’s so challenging to study in a rigorous way. There are various reasons for this, which I get into in greater detail in this episode. I also delve into some of the existing research on the subject and I ask, to what extent is the laughter aspect of Laughter Yoga the primary factor in promoting changes in people's well-being, when compared to 'non-laughter' exercise programmes?
