Productivity soars when a computer and its users interact at a pace (<400ms) that ensures that neither has to wait on the other.
Researcher at IBM Systems, famous for his paper on the human-computer interactions and the requirement for a computer response time to be 400 milliseconds or less.
In 1982 Walter J. Doherty and Ahrvind J. Thadani published, in the IBM Systems Journal, a research paper that set the requirement for computer response time to be 400 milliseconds, not 2,000 (2 seconds) which had been the previous standard. When a human being’s command was executed and returned an answer in under 400 milliseconds, it was deemed to exceed the Doherty threshold, and use of such applications were deemed to be “addicting” to users.
Loading...Users are strongly influenced by the aesthetics of any given interface, even when they try to evaluate the underlying functionality of the system.

The total complexity of a system is a constant: as we make the person’s interaction simpler, the hidden complexity behind the scenes increases.
A pioneering computer scientist who helped make it easier for us to interact with computers, whether cutting and pasting text or selecting text by dragging a cursor through it. Tesler worked at Xerox PARC, Apple, Amazon, and Yahoo!
Purposefully adding a delay to a process can actually increase its perceived value and instill a sense of trust, even when the process itself actually takes much less time.
