interference in relation to the Stroop effect 3 Interference and facilitation are two important aspects of automatic processes. Interference refers to the range to which one process encumbers performance of another‚ whereas facilitation indicates the extent to which one process assists performance of another. Through practice and maturation‚ reading progresses from a controlled process to one that is automatic‚ lessening the demands on attentional resources. Stroop reported one of the first studies

Previous evidence suggested that although automatic and controlled processes can work simultaneously‚ they can cause undesired interferences. In this experiment‚ colour names were replaced by colour-related words in the Stroop condition and it was found that the Stroop effect

Nuclear Power Stations 8.4.1: The firing of neutron at a heavy nucleus may result in the nucleus splitting‚ releasing free neutrons and lighter nuclei; which can then collide with other nuclei and resulting in the same process. This is a fission chain reaction. 8.4.2: In a fission reaction‚ if you can remove the emitted neutrons from the fissionable material‚ then you can control the rate at which the chain reaction proceeds. A fission reaction whereby the reaction is allowed to proceed without
