Conduct an experiment based on the materials in Chapter 7 of Exploring Psychological Research Methods. Analyse the data and write a 2000 word report on this experiment.
Investigating the interference on controlled and automatic processing when stating the ink colour of colour-related words: A Stroop effect variation.
The interference of automatic processes on controlled processes was explored in an experiment based on the Stroop effect. Previous research found that it takes longer to name the ink colour a word is printed in if the word is the name of a colour. These results have been used to support a two-process theory of attention. In the current experiment a Stroop-type was employed, using colour-related words. The results showed a difference in the times taken on each condition, supporting the theory of two-process attentional processing.
Only a certain amount of the information that arrives at our senses is processed and any information that is not processed is disregarded. This process is referred to as attention and involves the allocation of cognitive resources. The presence of these processes suggest that the minds resources are limited in terms of the amount they can process. Simons and Levin (as cited in Edgar, 2007) demonstrated this in an experiment exploring ‘change blindness’ which proved evidence that information regarding a persons identity was often not processed and the person they were talking to could be switched without them noticing.
 Kahneman (as cited in Edgar, 2007) theorised that the reason for this is that the brain contains a limited-capacity central processer which has the task of analysing information from the senses and combining it with information already held in memory. This processor is limited in the amount of information it can process and as a consequence people can be unaware of many things around them.
This issue is explored further using dual-task studies in which participants are required to...
