Ain't that the truth?

The truth is a grey area: only fanatics, children and fools believe otherwise...and semanticists

Shake Can Well (Link)

Last month, I gave a talk at CamCos3, the text of which is now posted on LingBuzz. It was the first time I have ever given a theoretical talk in Cambridge, let alone an invited one. And by happy coincidence, this year marks the 30th anniversary of my graduation from Trinity Hall. All in all, a very pleasant and interesting homecoming.

Lost on me? (Chomsky quotes)

"One of the most effective devices is to encourage debate, but within a system of unspoken presuppositions that incorporate the basic principles of the doctrinal systems. These principles are therefore removed from inspection; they become the framework for thinkable thought, not objects of rational consideration."
― Noam Chomsky

A few weeks ago, this quote was published on the Noam Chomsky Quotes FaceBook page. It is of a piece with almost all of the other cited quotes on that page—Chomsky is as consistent as he is driven, as one would expect. It is at once obvious and insightful, and obviously insightful. For what it's worth, the observation seems to me to be patently, and depressingly true.

Yet while agreeing with this analysis as a piece of political science, I can't help wondering why Chomsky's politics in this regard does not lead (him or his close followers) to any reflection on his linguistics. To someone like myself, who has worked within and without generative grammar for nearly 30 years, the irony is thunderous: within the enchanted circle of Biolinguistics, the unspoken presuppositions of generative ideology—e.g. the autonomy, innateness and supremacy of I-language—have clearly become the framework of thinkable thought; they are not up for debate. I've been lucky enough to learn from a lot of smart people over my career. Some of them are hardline generativists, but many of them are not. While it is of course conceivable that MIT linguists have unique access to the secrets of natural language, it's vanishingly improbable. Thus, it is at least prudent to spread one's intellectual bets, which means sometimes thinking the unthinkable, and brooking some dissent.

Adding to the irony, just today there appeared another (once again, almost certainly correct) observation by Chomsky concerning Marx:

"I should add that I have never considered myself a "Marxist," and in fact regard such notions as "Marxist" (or "Freudian," etc.) as belonging more to the domain of organized religion than of rational analysis. Marx was a serious person, not a God. He had significant insights, of lasting value. Like anyone, he made mistakes, and much has happened in the past century that has escaped his vision."
― Noam Chomsky

A serious person, not a God.

Names and Faces, and Handedness (Preliminary Results)

Who would've guessed...? After years of not getting round to it, then (literally) months of preparation, I've been able over the past few weeks to run a new Language and Cognition experiment. Here are some preliminary results...

The study I've set up investigates possible correlations in "perceptual narrowing", comparing participants' ability to discriminate native vs. non-native phonemic contrasts with their ability to discriminate native vs. non-native Japanese vs. Caucasian faces (for anyone interested, there's some background information on my website). The experiment consists of two forced-choice discrimination tasks—XAB/ABX, for faces and sounds, respectively—plus a lexical familiarity pretest (to test whether participants are familiar with all of the English words carrying the phonemic contrasts).

Participants

To date, 43 Japanese undergraduate students have taken part in the first run of the experiment. The results below are based on 40 participants (including 4 left-handers: see below). Two participants, whose accuracy scores fell below two standard deviations from the overall mean, were dropped from the analysis. One other participant (subject #3), who reported spending her early childhood in the US, was also excluded from the present analysis.

Results—Faces

Apriori, one might have expected that (for Japanese participants) Japanese faces would be easier to discriminate than Caucasian faces. Right? Except, that's not what the data suggest (at first blush). See Figures 1 and 2. As these figures show, the Japanese faces elicit somewhat less accurate and slower responses, though it remains to be seen whether the differences are statistically reliable. (Of course, this might not be a fatal problem: it could just be that the 30 pairs of Western faces are just easier for contingent reasons. It depends on how the Western participants judge the two sets, and I won't find this out until April. In any case,  I'm mainly interested in probing cross-modal correlations within-subjects, so even if the overall results don't turn out quite as expected, there may still be interesting within subject correlations.

Figure 1. Overall, Asian faces are hardest to discriminate (though the effect may not be robust)...
Figure 2...and Japanese participants take longer to judge Japanese faces than Caucasian ones (overall).

At this point in the analysis, the interesting quirks come when one looks more closely. Among the other independent and control variables, besides NATIVENESS, I manipulated ISI—time between the offset of the target face and presentation of the two possible matches (500 vs. 1000ms), Presentation Time of the target face (100 vs. 200) msecs, and Orientation—whether the faces are presented upright or inverted (upside-down). I also recorded the between-subjects factor of Handedness, just because I have a hunch about this...

Taking Orientation first, Figure 3 shows that this matters a lot: as predicted, in every condition, upright faces are easier to identify than the same faces presented upside-down.  No surprise here. What is surprising, though, is that the inversion effect is probably only significant for Asian faces (in other words, for native faces!). Curiously, inverted Caucasian faces are not much harder to discriminate than when presented upright.


Figure 3. Interactions between Nativeness and Inversion. The chart here shows that—as expected—upright faces are easier to discriminate than inverted ones. No surprise here. What is surprising, though, is that the inversion effect is probably only significant for Asian faces (in other words, for native faces)

I haven't even started the interpretive stats yet, so some of these initial results may turn out to be spurious, but it looks like all of these factors interact in interesting ways. Perhaps most surprisingly, handedness seems to interact with the other variables in an interesting way: left-handers are better than right-handers overall—much better in certain conditions—but also appreciably worse in others. See Figures 4 and 5 below. (Less surprising was the apparently significant main effect of Orientation, though it is still curious that this effect is larger for left-handers than right-handers.)

Figure 4. As might have been predicted, it's harder—for everyone—to discriminate faces overall when they are upside down (INV) than the right way up. That's what we see in Figure 3. What is less expected are the sub-patterns revealed in Figure 4: left-handers seem to show a huge effect of orientation for native (Japanese) faces, but not for non-native (Caucasian) ones; right-handers, by contrast, are better overall at discriminating non-native faces, but relatively poor at discriminating native ones.
Figure 5. Shorter ISI results in greater accuracy, but only for native faces (for left-handers) and for non-native faces for (right-handers). Go figure!

Which is all very weird, until I looked again and realized that there were only 4 left-handed subjects in the set (42). So it may really be a freak result. More anon.

 Sounds 

As for the sounds, these have worked out almost exactly as predicted. Figures 6 and 7 shows the accuracy scores and response latencies to trials involving minimal phonemic contrasts in English and Japanese, embedded in real lexical items. The blue bars show the discriminability of the control items: /t/ vs. /d/, phonemic contrasts common to both languages. The red bars show participants' performance on test items, i.e. contrasts that are not shared by both languages: /l/ vs. /r/ in the English trials, phonemically short vs. long segments in the case of the Japanese trials. Within the test items, 'more difficult' English contrasts are those where the critical phoneme is non-initial in the syllable (e.g. prays/plays), in contrast to the more perceptible syllable-initial contrasts (low/row); for the Japanese items, differences in vowel length were predicted to be harder to detect than consonantal length contrasts.

Figures 6 and 7 clearly suggest main effects of LANGUAGE (English vs. Japanese) and TRIAL TYPE (Control vs. Test), also—possibly—a small main effect of ITEM DIFFICULTY, as well as a reliable interaction between language and trial type, as reflected in both dependent measures: the Japanese participants in the study are significantly less accurate and slower in correctly discriminating non-native phonemic contrasts—i.e., l vs. r—than in discriminating native ones (67% vs. 98%). Notice that there is no appreciable difference in the responses to English and Japanese control items (both >95%).

Figure 6. Sounds—Accuracy across Conditions
Figure 7. Sounds—RT across conditions

The sounds experiment also manipulated ISI, in this case, the delay between presentation of the second alternative sound and the target sound (either 2250 or 3250 msecs). Ceteris paribus, longer ISIs should increase task difficulty. However, as Figures 8 and 9 show, increasing ISI appears to have had no significant effect on overall accuracy, though there was a (possibly significant) increase in response latency in the English/Test Conditions.

Kanji, how I loathe thee!

Events of the last few weeks have led me to give some consideration to Japanese Kanji, and its moraic sidekicks, Katakana and Hiragana. For what it's worth: here's my dystopic theory of the Japanese writing systems.
 

The purpose of Kanji is: 
  • (i) to prevent (almost) anyone who has not been through six years of elementary education from learning the language, by blocking all feedback from written signs and messages; 
  • (ii) to waste children's time by focusing their attention on the brushstrokes of arbitrary symbols , when they could be learning content; 
  • (iii) to cause untold domestic and other friction between those who have already learned a few kanji, and those who are just starting out...

The contrasting purpose of katakana is: 

  • (i) to stymie the best efforts of Japanese speakers trying to learn English, by neutralizing crucial distinctions (not just light/right but also lunch/ranch), inserting superfluous syllables, and generating atrocious puns; 
  • (ii) to offend against the (a)esthetic sensibilities of almost everyone (except, perhaps, those who liked thin, angular cars like the Triumph TR7, or late-70s Ford Escort).
And then there's hiragana, whose purpose is much less clear, unless it be:
  • (i) to teach Japanese linguistics students about functional categories; 
  • (ii) indicate at a distance where one can buy cigarettes (by a curious quirk of history *tobacco* is invariably written in hiragana, rather than the expected katakana.) 
These would seem to be rather petty uses for a perfectly serviceable, almost attractive syllabary.
End of rant. 


Which is not to pretend that English orthography is perfect. Vietnamese is nice, though.

Der Schauende (cross-posting)

This will not be news to those of you who had a decent mathematical education, but it was to me. After 51 years, thanks to my son Sean's science homework, I've just learned that there is a difference between precision and accuracy. Really, I had no idea...

(Accuracy, it seems, is only for realists: but even relativists can be—relatively—precise.)

Now for some catch-up.

(Same series, though mine is an earlier edition)
A few months ago, I picked off the shelf a copy of Rilke's 'Der augewählten Gedichte, anderer Teil. (I don't have the erster Teil, unfortunately). This undated Insel Verlag edition was published in Leipzig, either just before or during the War, judging from the cover, and must have belonged to my uncle Kenneth (erstwhile Professor of German at Keele University), as do all of the few decent German books I now possess—including an early copy of Hermann Paul's Prinzipien der Sprachgeschichte, the translation of which will be on my to-do list, probably for ever. It won't happen today, that's for sure: I taught four 90-minute classes virtually back to back, without lunch, came home and cooked dinner, helped to bathe and put the kids in bed...

...Anyway—und dann und wann ein weißer Elephant' (which isn't in this collection, but still careers around my head at least once a week)—I was at my reading of 'Der Schauende' some months ago, and thought: Wow (or some such hint at the ineffable).

What a brilliant piece.

...Wie ist das klein, womit wir ringen
Was mit uns ringt, wie ist das groß:
ließen wir, ähnlicher den Dingen,
uns so vom großen Sturm bezwingen — 
wir würden weit und namenlos.

Was wir besiegen, ist das Kleine
und der Erfolg selbst macht uns klein...

Stunning, really. Disheartening, too: after hearing these too perfect lines, writing anything—saying anything—seems only to add more junk to an already overflowing landfill.

And so I looked on YouTube for a competent rendering of the poem, and found something quite dreadful, an object lesson in how not to read anything (not even a grocery list), in how a bad performance can utterly ruin even the finest lines.

But then I looked again today
And found the poem resurrect
by Oskar Werner, a man whose name,
though t'is renowned, I never knew
Till now — and more's the shame.

[with apologies to Heine]

YouTube taketh away, but giveth, too
...und dann und wann: ein Wunder — Click to play

Was wir besiegen, ist das Kleine
und der Erfolg selbst macht uns klein...

Postscript 10/25: This evening, browsing my subscriptions on Youtube, I came across this talk by Nigel Fabb (one of the other Nigel linguists) on verse design and verse delivery, focussing on Dylan Thomas' reading of his own and other's poetry. Fascinating material, interesting ideas:

Linguistics of Vietnamese

After some delay, I am pleased to have this in my hands at last. Thanks to Daniel Hole and Elisabeth Löbel, and the staff at Mouton for doing such an excellent job. If you are interested in Vietnamese grammar, please have your library order this!
