This episode is a review of a research paper by Angus James McLachlan of the Federation University, Australia. The basis of the research explored in today's episode was to examine how laughter is used by people as a marker in conversation to show that the meaning of the words aren’t meant to be serious in the context that they’re spoken (when accompanied by laughter) and also how the person doing the laughing is essentially trying to be friendly with the people they are chatting and laughing with.

Why is it that we laugh at stuff that's not 'funny', like walking straight into a pole? What kind of person does it make us if we laugh at someone else walking into a pole, but it's not funny when we do it? 

In this episode I explore how laughter is but one of a variety of tools that we use in our everyday lives to help us to cope with the unexpected - like watching our friends get chased by a grizzly bear. 

This episode also deals with the definitions of 'negotiate' and discord' in terms of how we negotiate the discordant aspects of life with laughter. In the next episode I'll be exploring the development of laughter as a life skill in infancy. 

Who is the Laughter Research podcast for? 

Maybe you're a performer and you want to understand more about why people laugh, or maybe you're a school teacher and you're wondering how laughter might benefit your students.

You may be working in a dangerous or stressful environment and you're wondering if laughter can help you to buffer some of that stress. Perhaps, in a more general sense, you're wondering if there is any evidence to show if laughter has potential to improve your well-being.

What is the purpose of laughter? Is it simply a physiological response to humour? If so, why do people find themselves laughing at extremely 'unfunny' moments, such as when they find themselves involved in a car crash, or when watching a distressing video? 

In this episode, I introduce the idea that laughter is more than an expression of humour appreciation and it is more likely to be a means to help us negotiate our way through this unpredictable world, by helping us to deal with some of life's challenges. 

Since the last episode (It's been a while), I've done the research on the ways in which people use laughter to help them get through the trials and tribulations of life and I earned a PhD for my troubles. 

I've also lived through a number of life changing challenges, including breaking my spine, and laughter has served me well. 

Now it's time to put these lessons into the magical format of audio and get back on the podcasting saddle. This episode marks the relaunch of the podcast and outlines the themes of resilience and recovery that are going to guide the future episodes. 

Today's podcast - released on none other than International Podcast Day...yes, it's a thing...is 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. http://doi.org/10.1121/1.2932088

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. http://doi.org/10.1093/deafed/enl008

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.
