hierarchy‚ and the most complex cognitive (e.g. memory‚ problem solving) systems are located at the top of the hierarchy. Information can flow both from the bottom of the system to the top of the system and from the top of the system to the bottom of the system. When information flows from the top of the system to the bottom of the system this is called "top-down" processing. The implications of this top to bottom flow if information is that information coming into the system (perceptually) can

all my weight on ankle. In that moment I had no reaction initially‚ and then suddenly I felt an overcast of severe pain. The top-down processing in this situation was that I had to think and process what just happened to my ankle‚ and then my pain sensory kicked in. This is a clear example of top down processing because my thoughts were initiated first and then it flowed down to my senses. This would be an example of a bottom up processing approach if I applied ice to the injured area. The cold temperature

Joint application design (JAD) is a process used in the prototyping life cycle area of the Dynamic Systems Development Method (DSDM) to collect business requirements while developing new information systems for a company. "The JAD process also includes approaches for enhancing user participation‚ expediting development‚ and improving the quality of specifications." It consists of a workshop where “knowledge workers and IT specialists meet‚ sometimes for several days‚ to define and review the business

Lab O6 – Equilibrium Lab Application Purpose: An introduction to the qualitative aspects of chemical equilibrium. Starting with a reaction at equilibrium‚ one will change the concentration of various ions present in the equilibrium‚ and record the states of the changing equilibrium through observation. Theory: Equilibrium- the point at which a solution has become perfectly saturated; when their forward and reverse reaction rates are equal Concentration- a measurement of how much solute

Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules
