Giggles and gargles

imai-galagala

A 2005 study suggests that Japanese ideophones of laughter activate striatal reward centers in the brain, but I think the results should be treated with a pinch of salt. Speaking of salt, Japanese gargle with salt water regularly as a prevention against the common cold; they even have an ideophone for it (but so do we, don’t we?). That’s giggles and gargles today. Let’s tackle the giggles first.

Ideophones that make you feel good

A 2005 brain imaging study suggests that ideophones for laughter, but not nonsense syllables, activate reward areas in the brain. Here is the abstract:

The neurobiological reward components of laughter induced by words were investigated. A functional magnetic resonance imaging-based brain imaging study demonstrated that visualization of mimic words and emotional facial expressionwords, highly suggestive of laughter, heard by the ear, significantly activate striatal reward centers, including the putamen/caudate/nucleus accumbens, prefrontal cortices, dorsal anterior cingulate cortex and the supplementary motor area, while non-mimic words under the same task that did not imply laughter do not activate these areas in humans. We tested a specific hypothesis that implicit laughter modulates the striatal dopaminergic reward centers by image formation of onomatopoeic words implying laughter and successfully confirmed the hypothesis. [Osaka & Osaka 2005]

Since ideophones have been claimed to somehow establish a more direct link between sounds and sensations than other words, brain imaging of ideophone production and comprehension is an exciting research area. Basically, the finding of Osaka & Osaka is that Japanese ideophones for laughter activate striatal reward areas, just like real laughter and other pleasurable activities do. The ideophones used are ‘ghera-ghera’ (strong laughter), ‘nikoh-nikoh’ (strong), ‘kusu-kusu’ (medium), ‘niyah-niyah’ (medium), ‘herahherah’ (weak) and ‘nitah-nitah’ (weak) (p. 1622, romanization by the authors).

But is it ideophony?

That is an interesting result, but I wonder: does the effect really occur because the words are ideophones, evoking the experience of laughter through their sound-symbolic form and imagistic meaning? Or could it simply be due to the fact that the words have to do with laughter? We can’t tell, because the baseline comparison is not with non-ideophonic real words but with nonsense words (called ‘nonsense phonemes’ by the authors). Since non-ideophonic laughter-related words have been kept out of the comparison, we cannot be sure that ideophony (onomatopoeia/mimesis) is causing the effect, although this is what the authors would like to claim.

There is some reason to think that embodied semantics might be enough to induce such effects; think for example of the brain imaging studies showing that certain sensori-motor cortex areas not only upon tactile stimulation of the body part in question (e.g. the hand), but also during the processing of body part terms and verbs implying them (e.g. hand, grasp; Rohrer 2001). So the question is: would the effect found by Osaka & Osaka also occur with non-ideophonic laughter-related words in Japanese? For comparison, it would also be good to have a not so heavily ideophonic language thrown in. Would the English verbs ‘giggle’ and ‘laugh’ also trigger the effect? Sound-symbolic ‘giggle’ moreso than ‘laughter’? Then things start to be really interesting.

A related problem is the claim that ‘image formation of onomatopoeic words’ plays a role in the effect. Once again this would be an interesting claim to test; native speakers of ideophonic languages often report that ideophones evoke vivid images. But in this study it remains an untested background assumption. The way the experiment is set up doesn’t seem to allow for any inferences about it. For all we know the effect might just be due to an association between the sound and the experience of laughter; it is not at all obvious why image formation would come in. One way to approach this issue would be to do imaging studies of ideophones that don’t imitate sounds, but other sensory events.

[Update: Kimi Akita notes that the stimuli, described by the authors as ‘laughter onomatopoeic words’ (p. 1622), actually mix sound-imitating ideophones (geragera and kusukusu) and movement/visual pattern-imitating ideophones (nikoniko, niyaniya, herahera, and nitanita). It doesn’t really help that all of the results are averaged. I might add that Japanese itself does distinguish the two groups by the terms giongo and gitaigo, even though to a non-native speaker the actual categorization in this case isn’t obvious (I would’ve grouped herahera with geragera, and I wonder what kusukusu laughter sounds like…).]

Gargles

So much for the giggles. What about the gargles? The gorgeous gargling girl above is one of the stimuli used by Prof. Mutsumi Imai in a study of child-directed speech in Japanese. One of her findings is that when describing scenes like this to their child, mothers will tend to use more mimetics (ideophones) than when they are describing the same scene to an adult.

I’m planning to do a pilot in Kawu using prof. Imai’s stimuli, and one question is to what extent the original material would be usable in a West-African context. The idea is that the stimuli can be described using ideophones. Since most of the illustrations are simple events (jumping down, jumping across, throwing, rolling sth. up) I think they should be usable by and large. Perhaps the skin color will have to be changed — I prefer stimuli to be as culturally inconspicuous as possible — though the question is whether that really would affect what we’re after.

However, the one stimulus that I think won’t be familiar is the gargling one above. In the Japanese context, it is meant to elicit the ideophone garagara, probably in the light verb construction X suru ‘do X’. But in Kawu, the scene isn’t very recognizable. People usually drink from calebashes (or their hands), though whites are known to prefer cups — so my guess is that the girl would simply be seen as drinking. Since gargling is not a culturally salient event in Mawu society, I don’t think people would readily think of it, even if there happens to be an ideophonic word for it.

The Japanese ideophone for gargling is garagara. Interestingly, Kimi Akita tells me that “Japanese mothers tell their kids to pronounce “garagara” while gargling. This is because the articulation (especially, that of the velar consonant) of the mimetic is believed to help kids gargle successfully.” Now that’s an interesting intermingling of habitus and embodied meaning. I tried this (without any appreciable gargling experience) and nearly choked. This gives a whole new meaning to the phrase “Embodied semantics is a killer idea”!
