In Cumrun Vafa's "Lightning Introduction" to string theory in his Lectures on Strings and Dualities , he instroduces supersymmetry to string theory thus:
in addition to the coordinates [tex]X^{\mu}[/tex] we also have anticommuting fermionic coordinates [tex]\psi_{L,R}^{\mu}[/tex] which are spacetime vectors but fermionic spinors on the worldsheet whose chirality is denoted by subscript L, R. I have no problem with the anticommutative coordinates themselve, but how does the worldsheet make vectors in spacetime appear as spinors?

Sorry about that. It's fixed now.
