Joanne: Besides the ones you have already received, there is
Pedersen, N.L., Plomin, R., Nesselroade, J.R. & McClern, G.E. (1992) A
quantitative genetic analysis of cognitive abilities during the second
half of the life span. _Psychological Science_. 3, 346-353.
If all you want are summaries (and charts of summaries), Plomin's book
(Plomin, DeFries, McClearn & Rutter, _Behavioral Genetics_ third
edition, 1997), is good. He has a chart on page 140 that has "old"
separated twin data (from Cyril Burt's days) as well as "new" twin data
(i.e. Bouchard's Minnestota twin data). I's be happy to send a copy if
you can't find it easily.
