Contrast with the step-by-step (serial) processing of most computers and of conscious problem solving the minimum stimulation needed to detect a particular stimulus 50 percent of the time information processing guided by higher-level mental process, as when we construct perceptions drawing out our experience and expectation conversion of one form of energy into another. In sensation, the transforming of stimulus energies into neural impulses
