Humor comprehension and appreciation: an FMRI study.

Humor is a unique ability in human beings. Suls [A two-stage model for the appreciation of jokes and cartoons. In P. E. Goldstein & J. H. McGhee (Eds.), The psychology of humour. Theoretical perspectives and empirical issues. New York: Academic Press, 1972, pp. 81-100] proposed a two-stage model of humor: detection and resolution of incongruity. Incongruity is generated when a prediction is not confirmed in the final part of a story. To comprehend humor, it is necessary to revisit the story, transforming an incongruous situation into a funny, congruous one. Patient and neuroimaging studies carried out until now lead to different outcomes. In particular, patient studies found that right brain-lesion patients have difficulties in humor comprehension, whereas neuroimaging studies suggested a major involvement of the left hemisphere in both humor detection and comprehension. To prevent activation of the left hemisphere due to language processing, we devised a nonverbal task comprising cartoon pairs. Our findings demonstrate activation of both the left and the right hemispheres when comparing funny versus nonfunny cartoons. In particular, we found activation of the right inferior frontal gyrus (BA 47), the left superior temporal gyrus (BA 38), the left middle temporal gyrus (BA 21), and the left cerebellum. These areas were also activated in a nonverbal task exploring attribution of intention [Brunet, E., Sarfati, Y., Hardy-Bayle, M. C., & Decety, J. A PET investigation of the attribution of intentions with a nonverbal task. Neuroimage, 11, 157-166, 2000]. We hypothesize that the resolution of incongruity might occur through a process of intention attribution. We also asked subjects to rate the funniness of each cartoon pair. A parametric analysis showed that the left amygdala was activated in relation to subjective amusement. We hypothesize that the amygdala plays a key role in giving humor an emotional dimension.

Perception of humor in cartoon riddles by adults with intellectual disability.

Young adults with intellectual disability, 15 with IQs of 55 to 75 and 15 with IQs of 40 to 54, rated 12 cartoon riddles of six levels of difficulty. Mirth and comprehension were also scored. Analyses indicated that participants considered the jokes funny but there was a strong tendency to respond to the visual aspects of the jokes rather than to the auditory aspects.

What's funny about nursing?

The authors examine the topic of humour and argue that humour is needed as one of many skills within the nurse patient relationship. We advance the view that humour has been well researched as an agent of therapeutic value and as a communication tool which helps to relieve stress, but, to date is not used to its fullest potential and tends therefore to be underestimated in both general and psychiatric nursing areas. Humour has benefits for both the nurse and the patient having psychological benefits and a vast array of physiological advantages and is regarded by those who use it as a social lubricant acting as a positive in nurse patient relationships. We also argue that it is essential that nurses know when to use humour as timing and appropriateness is imperative in order for it to be most effective. Humour can be used in all areas of clinical nursing practice and may prove useful in being a reliable predictor over the course of a patient's illness. The use of humour can help improve the nurse-patient relationship by initially breaking the ice between nurse and patient. This alternative mode of delivery can then be foundational to other areas of the nurse patient relationship such as self-disclosure, the enhancement of learning and relieving stress. Furthermore, it helps to facilitate and promote mutual health and well being for both the patient and the nurse. The usage of humour in psychiatric nurse settings is discussed and the benefits to both the patients and their staff are outlined as being of immense therapeutic value. The literature perhaps tends to skirt around these benefits somewhat, as psychiatry and laughter in partnership are not really considered important discursive topics.

Humor and smiling: cortical regions selective for cognitive, affective, and volitional components.

BACKGROUND: The interrelationships among humor, smiling, and grinning have fascinated philosophers for millennia and neurologists for over a century. A functional dissociation between emotional facial expressions and those under voluntary control was suggested decades ago. Recent functional imaging studies, however, have been somewhat at odds with older studies with respect to the role of the right frontal cortex in the perception of humor. METHODS: Blood oxygen level-dependent (BOLD) activity was measured in 13 subjects during the presentation of "funny" vs "nonfunny" versions of essentially the same cartoons and compared with BOLD activity associated with "merely grinning" at similar nonfunny cartoons via fMRI. RESULTS: Humor perception was correlated with BOLD activity in the left temporo-occipitoparietal junction and left prefrontal cortex and humor-associated smiling (recorded with an MR-compatible video camera) with bilateral activity in the basal temporal lobes. Unexpectedly, both conditions were also accompanied by a decrease in BOLD activity in the right orbitofrontal cortex. Voluntary "grinning" in the absence of humorous stimuli was accompanied by bilateral activity in the facial motor regions. CONCLUSIONS: These results confirm the clinically derived hypothesis of separate cortical regions responsible for the production of emotionally driven vs voluntary facial expressions. The right orbitofrontal decrease reconciles inconsistencies between clinical and functional imaging findings and may reflect a disinhibition of facial emotional expression.

Holiday waistline. Time to consensus: the effect of the stomach on consensus decision-making at large conferences.

INTRODUCTION: The factors affecting decision-making at consensus conferences are not well understood. This paper studies the complex association between time to consensus (TTC) and the timing and quality of food, as well as the self-reported level of frustration (PITA factor) with the question at hand. METHODS: We came, we saw, we ate. RESULTS: There was an association between the TTC and the time to eating, especially lunch. There was a trend to faster TTC the better the researchers rated the food. The speed of decision-making was also increased when the PITA score was high, especially late in the day. INTERPRETATION: Organizers of large consensus conferences need to be aware of these factors in decision-making and should try to use them to get more controversial items voted to their satisfaction.

Health in strip cartoons.

Strip cartoons are among the most vivid means of communication at our disposal, and they are particularly popular with the young. Medical matters have featured in many stories, though usually in a peripheral role. Could more be done to use this powerful medium, or would deliberate exploitation destroy it?

The appreciation of visual jokes in people with schizophrenia: a study of 'mentalizing' ability.

It has been suggested that certain characteristic symptoms of schizophrenia reflect a specific deficit in the ability to attribute mental states to others ('mentalizing'). Patients with negative features, particularly social withdrawal and blunted affect, those with thought disorder and patients with paranoid symptoms have difficulties when they try to infer what is going on in the minds of other people. This study examines this notion using two sets of cartoon jokes. While the first set can be understood purely using physical and semantic analysis, the second set requires that the viewer appreciates the mental state of the main character in order to 'get' the joke. For control subjects there was no difference in the ability to understand the two types of joke, while the schizophrenic patients found the mental state jokes significantly more difficult to understand. This effect was most marked in patients with behavioural disorders and those reporting passivity experiences. Those with paranoid delusions also showed a selective comprehension deficit with the mental state stimuli. Patients who were symptom free at the time of testing showed normal performance.

A study of storytelling, humour and learning in medicine.

Story telling is a fundamental part of clinical practice. It provides the mechanism by which doctors and patients communicate and understand the meaning of illness and possible ways of dealing with it. Humour is a particular aspect of story telling and, while there are some negative aspects, generally does have a therapeutic benefit. The physiological effects of laughter are considerable. Both story telling and humour are important for learning and are complementary to the more formal learning from text books and lectures. Stories assist in the development of emotional knowledge. The hypothesis of the contagious theory of behaviour change is presented as a way in which ideas are transmitted from one person to another.
