Joel, i think it would have to be a function of the construct assessed,
right? so, if by "To what extent do speed and power tests measure the
same constructs?" you mean the _*same test*_ administered under speeded
and power conditions, then the answer would have to be "no" b/c
additional variance, maybe construct-relevant or construct-irrelevant
has been introduced into the test scores. consequently, one would
expect the convergence b/n the two sets of scores to be low
and "Do speed tests add validity over power tests?" => again, it will
seem the answer would depend on the constructs assessed by the two
tests. thus, for example, tests of processing speed and reaction time,
are by definition speeded tests; whereas for example tests of fluid
intelligence (e.g., the Ravens) and declarative knowledge are typically
better conceptualized as being closer to the power end of the continuum.
hope this helpful?
