A total of 253 British and 318 American students were asked to make various estimates of overall intelligence as well as Gardner's (1999a) new list of 10 multiple intelligences. They made these estimations (11 in all) for themselves, their partner, and for various well-known figures such as Prince Charles, Tony Blair, Bill Gates, and Bill Clinton. Following previous research there were various sex and nationality differences in self-estimated IQ: Males rated themselves higher on verbal, logical, spatial, and spiritual IQ compared to females. Females rated their male partner as having lower verbal and spiritual, but higher spatial IQ than was the case when males rated their female partners. Participants considered Bill Clinton (2 points) and Prince Charles (5 points) less intelligent than themselves, but Tony Blair (5 points) and Bill Gates (15 points) more intelligent than themselves. Multiple regressions indicated that the best predictors of one's overall IQ estimates were logical, verbal, existential, and spatial IQ. Factor analysis of the 10 and then 8 self-estimated scores did not confirm Gardner's classification of multiple intelligences. Results are discussed in terms of the growing literature in the self-estimates of intelligence, as well as limitations of that approach.

First Time

A classification of all four-circulant extremal codes of length 32 over F2 + uF2 is done by using four-circulant binary self-dual codes of length 32 of minimum weights 6 and 8. As Gray images of these codes, a substantial number of extremal binary self-dual codes of length 64 are obtained. In particular a new code with ?=80 in W64,2 is found. Then applying an extension method from the literature to extremal self-dual codes of length 64, we have found many extremal binary self-dual codes of length 66. Among those, five of them are new codes in the sense that codes with these weight enumerators are constructed for the first time. These codes have the values ?=1, 30, 34, 84, 94 in W66,1.

It is known that there is no extremal singly even self-dual $[n,n/2,d]$ code with minimal shadow for $(n,d)=(24m+2,4m+4)$, $(24m+4,4m+4)$, $(24m+6,4m+4)$, $(24m+10,4m+4)$ and $(24m+22,4m+6)$. In this paper, we study singly even self-dual codes with minimal shadow having minimum weight $d-2$ for these $(n,d)$. For $n=24m+2$, $24m+4$ and $24m+10$, we show that the weight enumerator of a singly even self-dual $[n,n/2,4m+2]$ code with minimal shadow is uniquely determined and we also show that there is no singly even self-dual $[n,n/2,4m+2]$ code with minimal shadow for $m \ge 155$, $m \ge 156$ and $m \ge 160$, respectively. We demonstrate that the weight enumerator of a singly even self-dual code with minimal shadow is not uniquely determined for parameters $[24m+6,12m+3,4m+2]$ and $[24m+22,12m+11,4m+4]$.
