Is it possible to scientifically measure someone’s sense of humour? Are there universally good or bad jokes that make people laugh no matter their gender, profession or cultural background? These are some of the questions answered by the doctoral thesis Sentido del Humor: Construcción de la Escala de Apreciación del Humor (Sense of humour: building of the appreciation of humour scale), carried out by Hugo Carretero Dios, researcher in the Department of Social Psychology and Methodology of Behavioural Science at the University of Granada.

This study, directed by researchers Cristino Pérez Meléndez and Gualberto Buela Casal, is the first work in Spain stemming from Psychology aimed at measuring people’s sense of humour to analyse the psychological variables related to humour. Carretero Dios analysed more than 1,500 people between the ages of 18 and 80 and a similar number of men and women.

This study focused on the following types of humour: sexual humour, black humour, humour degrading to men, humour degrading to women, simple humour and complex humour. The study provided the first scientifically approved evaluation instrument in Spain to evaluate humour appreciation. Moreover, it helped to improve other instruments used in other countries.

Generational change
Carretero Dios observed a generational change in the women’s preferences to the different types of humour. “There has been change in women’s values and roles in our society,” says Carretero Dios. “In people over 45-50, we observed that both men and women laughed more at jokes degrading to women than those degrading to men”. At the same time, both men and women showed more rejection to jokes degrading to men.

However, among the participants between 18-25 years old, the trend was different and men and women had different reactions. Men laugh more at jokes degrading to women and reject those degrading to men. By contrast, women laugh more at jokes degrading to men and reject those degrading to women. Indeed, this trend is more pronounced in women.

Could these findings show a change in educational values or even a new pattern in the roles played by women? According to Carretero Dios, “humour is useful to study the predominant values of a specific society, and is also a powerful instrument to show cultural trends (beliefs, actions, etc). We only need to remember the conflict caused by the Mohammed cartoons last year, in which humour clashed with religion.”

Universal humour does not exist
One of the conclusions of this study was that the different personalities of people help to differentiate specific humour preferences. “Consequently, there are no universally good or bad jokes — humour depends on the person,” says Carretero Dios.

Contrary to what we would expect, “a particular person’s momentary state of mind in a humourous situation, such as on hearing a joke, does not imply that the person finds that particular situation funny,” explains Carretero Dios. A person’s taste in humour “is rather an intellectual or aesthetic question, emotion or state of mind being more related to physiological and behavioural factors of sense of humour than an opinion of what we think is funny.”

Humour in hospitals
Carretero Dios is the president of the Spanish Cultural Association «Titiritas: Humor y Salud» (Titiritas: humour and health), which works with hospitals and aims at bringing humour to these centres to make this context more human and see the influence of this humour in different parameters. This association has been awarded best non-profit youth organisation in the Andalusian region by the city of Granada. Moreover, it receives funding from the Area of Culture of the Andalusian Institute of Youth. Recently, this association participated in a study that analysed the impact of humour on the behaviour of psychiatric patients in an acute unit. This study was chosen by the American association HumorLab as one of the four most important studies on an international level on sense of humour in 2006.

The results of this thesis were recently presented at the International Humour Conference, sponsored and organised by the International Society of Humor Studies, the most important scientific association in the world. The results were also published in prestigious journals such as the International Journal of Humor Research (the most important scientific journal in the world on the study of sense of humour), Psicothema and Análisis y Modificación de Conducta.

Surprising as it may seem, there are people who can smell sounds, see smells or hear colours. Actually, all of as, at some point in our lives, have had this skill (some authors affirm that it is common in newborns). This phenomenon, called “synaesthesia” – from the Greek “syn” (with) and “aisthesis” (sensation) – consists of the pairing of two bodily senses by which the perception of a determined stimulus activates a different subjective perception with no external stimulus (in science, the evoker stimulus is called inducer and the additional experience concurrent).

In the department of Experimental Psychology and Physiology at the University of Granada, a research group is carrying out pioneer work in Spain on the systematic study of synaesthesia and its relation with perception and emotions. Professor Juan Lupiáñez Castillo and Alicia Callejas Sevilla have devoted many years to the study of this unknown but interesting phenomenon, which affects approximately one person out of every thousand. Many of these people do not even know that they are synaesthetes, as they think they perceive the world normally.

Pioneers

Callejas’ doctoral thesis is one of the most detailed studies on this phenomenon at an international level, and it is probably the first doctoral thesis on this topic in Europe. Her study covers the various forms of synaesthesia focussing on the most common one: the grapheme-colour type (for people with this form of synaesthesia, letters, words and numbers evoke colours in an automatic and involuntary way).

One of the distinctive characteristics of this form of synaesthesia is the fact that people are certain about their perceptions: they feel that their way of experiencing the world is correct, and they become disappointed when they realize there is something that is not quite right. ‘Therefore, when a person with grapheme-colour synaesthesia indicates that the word table is blue, it is quite probable that if he or she ever sees the same word written in a colour other than blue, this word will appear to him or her as wrong and consider it a mistake. The synaesthete might even point out that the word is ugly or that he or she does not like it because it is not correct,’ affirms Callejas. Consequently, finding the word table written in red might be unpleasant whereas seeing it in blue might be agreeable. This emotional reaction associated with how synaesthetes perceive consistent or inconsistent stimuli is an extremely interesting subject and has been studied for the first time in this doctoral thesis.

Irrepressible reactions

Some of Callejas’ conclusions show that these emotional reactions occur automatically and can not be ignored. Moreover, they can affect the synaesthete to the point of slanting his or her preferences when faced with certain stimuli which correspond to his or her inner experiences. Even more important is the fact that these emotions can transform how they perceive events associated with these experiences. These events may have no emotional meaning initially but they can become more or less pleasant if they take place at the same time the synaesthete finds a word in the correct or incorrect colour.

‘Then, there are people for whom time units evoke colours – explains the researcher. It is also common for a synaesthete to see colours when listening to words, sounds in general or music notes (people who can see music, for instance). There are also cases, although fewer, where people can see colours in flavours, others perceive flavours or experience touch sensations when listening to different sounds, some link flavours to touch sensations, etc.’

An permanent vision

These researchers from Granada underline that synaesthetes always experience the same vision, synaesthesia is permanent (a given stimulus always evokes the same colour for one person) and idiosyncratic (it is different for each person). Therefore, if for a synaesthete the word dog is red, every time he or she sees it, it will be perceived as red.

Even though synaesthesia has been known for a long time, its scientific study is relatively recent. Writings such as the Castel one, in which reference is made to previous studies about a synaesthesia case in a blind person, are found in the 18th century. The evolution of the study of this phenomenon has been spectacular – the number of researchers working on this topic is constantly increasing, as will be evident in the Conference which will take place in Granada – and, as the phase of proving that this phenomenon exists has been overcome, explains Alicia Callejas, ‘we are starting to approach questions of major theoretical importance, and to develop adequate study strategies.’ The results of her research have been published in the following prestigious scientific journals, among others: Cortex, Experimental Brain Research and Consciousness and Cognition.

Nowadays, the research field goes from grapheme-colour synaesthesia to other forms never studied before: flavours evoked by music or words (lexical-gustatory synaesthesia), space structures linked to time units, colours and music, etc.
