Signal detection theory (SDT) can be useful for many different situations, specifically two choice tasks which deal with performance (Turner, Zandt&Brown, 2011). Signal detection theory also has the ability to determine how well individuals can detect and discriminate information (DeCarlo, 2002). Signal detection theory is often used as a tool for decision making as well (Lynn&Barrett, 2014). Signal detection theory can help describe how individuals separate meaningful information from unnecessary background information (Lynn&Barrett, 2014). The purpose of this experiment was to measure two separate levels of stimulus during video presentations. The researcher planned to determine whether duration of a light being flashed during the video had an effect on the subjects ability to perceive the flash. As well as whether the colour of the light being flashed during the video had any additional effects. A study done on high speed motion determined that when humans observe even the slighted motion they are able to perceive large illusions (Glennerster, Cavanagh, Ito & Seno, 2013). During a set of three video clips participants were shown either a red or blue flash of light which was presented for either 115 milliseconds or 75 milliseconds. After the experiment took place students conducted a binomial sign test to …show more content…
Researchers first measured a group of (#) drivers response time when they had no distractions present (Merat&Jamson,2008). Next drivers response time was measured with one detection and one in vehicle information system task i.e. phone, global positioning system, etc. (Merat&Jamson,2008). In comparison to the study done on the effect on in vehicle technology (Merat&Jamson,2008) both found that when faced with background noise it becomes more difficult to respond to the stimuli
