We show that there are qualitative differences between the temperaturedependence of the spin and charge correlations in the normal state of the 2Dattractive Hubbard model using quantum Monte Carlo simulations. Theone-particle density of states shows a pseudogap above $\tc$ with a depleted$N(0)$ with decreasing $T$. The susceptibility $\cs$ and the low frequency spinspectral weight track $N(0)$, which explains the spin-gap scaling: $1/T_1T \sim\cs(T)$. However the charge channel is dominated by collective behavior and thecompressibility $dn/d\mu$ is $T$-independent. This anomalous ``spin-chargeseparation'' is shown to exist even at intermediate $|U|$ where the momentumdistribution $n(\bk)$ gives evidence for degenerate Fermi system.Comment: 4 pages (twocolumn format), 5 Postscript figure
