HUMANS SURPASS MACHINES IN THE: detection perception judgment induction Improvisation longterm memory * Ability to detect small amounts of visual or acoustic energy * Ability to perceive patterns of light or sound * Ability to improvise and use flexible procedures * Ability to store very large amounts of information for long periods and to recall relevant facts at the appropriate time * Ability to reason inductively * Ability to exercise judgment MACHINES SURPASS HUMANS IN THE: speed computation replication simultaneous operations short term memory * Ability to respond quickly to control signals, and to apply great force smoothly and precisely * Ability to perform repetitive, routine tasks * Ability to store information briefly and then to erase it completely * Ability to reason deductively, including computational ability * Ability to handle highly complex operations, i.e., to do many different things at once.
