Investigating the effect of using pairs of either similar or dissimilar stimuli during a dual-task experiment. Abstract The aim of the experiment was to investigate whether using pairs of either similar or dissimilar stimuli during a dual-task would affect response times. Participants were asked to complete a dual-task in which they selected either colours or numbers from a list of words, while at the same time verbally answering a series of mental arithmetic questions. The results of the experiment showed that response times when similar stimuli were used (both tasks relating to numbers) were slower than when dissimilar stimuli were used (tasks related to colours and numbers). This provides support for the theory that we have pools of resources which are allocated to processing different types of stimuli, and thus drawing on one resource pool for two tasks will increase the response time compared to drawing on two separate resource pools. Hypotheses The experimental...
