Introduction In the early 1900’s, the Stroop effect was discovered by J.Ridley Stroop. Two cognitive processes are involved with this theory. These are controlled and automatic processing. This was put forward by Schneider and Shiffrin in 1977. It is said that a skill or behaviour is autonomous when the person does not need direct attention. Cycling, typing and driving and many others are behaviours and skills that have said to be autonomous by cognitive psychologists. To test autonomous behaviour, psychologists have to place participants in such a situations where the automatic response it in direct conflict with the desired behaviour. The Stroop effect is a famous example of this type on influence. When a participant is presented with common nouns printed in different colours, it is relatively easy for the participants to name the colour of the ink the noun is printed in. For example the word “House” printed in green ink. However in other Stroop tasks where the participants are asked to name the colour of the ink the word of the colour in printed in, then it is much harder and takes more time. For example, the word RED printed in blue ink like this, RED. The process of reading words and naming colour words may interfere with each other and the Stroop effect can test that. This relates back to the cognitive processes: controlled and automatic. Processes that require attention from the individual, voluntary and are usually slow are controlled. Automatic processes are involuntary and usually fast. The theory also says that capacity limitation was unaffected, which means that at the same time, other performances would not be affected. This theory was to do with controlled and automatic processing, and stated that the former was slow and the latter; fast, and thus differentiated between the two. The theory also stated that automatic processing was unaffected
