linear relationships with low p values
They validated their results by surveying 500 people and asking them to rank these tasks on an abstract/concrete spectrum. This produced generally significant agreement with the computer generated levels. The p values were encouragingly low (4E-4 to 9E-9) though so alas were the r values (0.2 to 0.5). It would also have been interesting to compare these responses across different cultures. But this is the least important aspect of the study.
Certainly these results must be interpreted with due caution: the techniques they use are powerful and very interesting but (as is clear from Fig 6) the correlations on which they are based are not by any means perfect and as they note the linear regression they use for Fig 6 merely approximated the actual distributions - which are all shown as small subsets next to each word. But clearly this is a major step forward, and the kind of great, deep intellectual achievement that one would expect from Hava.
Very interesting that Naming (covert) has the highest level of abstraction. Not least because the one intellectual job God gives to Adam in Genesis is ... naming!
