Unarchiving classic experiments

I’ve tried to open the archives several times on various mac versions of experiments but have gotten an error. When I try to open the archive, Archive Utility gives me the error: Unable to unarchive “sternberg_mac.zip” into “Desktop”. (Error 1 - Operation not permitted.)

Did I miss something about where the archives are supposed to be opened? Any help will be greatly appreciated!

Sorry about the problem. The Mac experiments were compiled on Windows using PKZIP. We re-compressed everything on the Mac and re-posted them. It should work now.
