Reaction Time Essay

Summary This investigate aimed to determine the reply time of the run musician and using the subtractive method identify the selection time and identification time of the actor. The trys had unity thespian who participated in a extreme of 6 tastes two experiments requi expiration a unsubdivided answer with a single stimulation and 4 experiments that inevitable a more complicated reception. Keywords Subtractive method the procedure of estimating the time it takes to carry out various cognitive operations.Simple answer this reaction time line has a single input and requires unaccompanied a single reaction Choice reaction In this reaction time task there are more than mavin stimulus and more than one response. to each one stimulus has its hold response. Donders A B and C reactions In this reaction time task there is more than one stimulus but only one stimulus is linked with a response. Introduction Donders A B and C reactions have been used to determine the t ime it takes to perform cognitive operations for quite around time now.In these experiments we aimed to use light and dear stimuli in the react time tasks to determine someone base time, Identification time and selection time. Using one female college student (23 years) and one individual recording the different reaction times. The experiments took place over a period of two days, with the first experiment taking place on one subsequentlynoon and the next 5 experiments a week afterward in the afternoon again. 2. Methods 2. 2 Apparatus and materials.One pen and paper to record reaction times, one Reaction task railroad car which came equipped with headphones for sound stimuli, a screen for visual stimuli and a plank of firings colored red, yellow and unfledged for responses. 2. 3 Procedure Pilot Test The musician stood on the reaction task side of the railway car and put on the headphones after having been already instructed to complot the red outlet when they heard so me(prenominal) sound and visual stimulus.The observer then zeal the machine to pilot test, simple reaction test and selected the color red. The observer then gave a visual signal to the participant to permit them agnize the experiment was about to begin. In this pilot test the participant was needful to stuff the red button each time they saw the red light fritter when it was accompanied with a congressman that said red. At the residual of a test a book signal was apt(p) by the observer to the participant to let them know the task was over.The light and sound stimuli were precondition for a total of 20 times if the participant did not make any mistakes (that is pressure sensationed the red but only when both stimuli were abandoned) then the pilot test was pass with flying colorsd successfully, if not the machine would reset itself and would have to be set again and the test would be administered again. This stage was also a learning phase for both participants and o bservers as both were using this type of machine for the first time. Experiment 1.The participant stood on the test side of the machine and put on a pair of headphones after having been already instructed they were required to press the red button each time they saw a red light. The observer then set the machine to real test, selected simple reaction and selected the color red. . There was no signal given to the participant as to when simply the experiment would begin by the observer but they were told to be ready as soon as they saw the light the experiment had begun.At the end of the experiment a snuff it signal was given by the observer to the participant to let them know the task was over. The stimulus that required a reaction in the experiment was given 19 times and the experiment was only bump off if the participant make no mistakes. Each reaction time was noted by the observer. Experiment 2 The participant stood on the test side of the machine and put on a pair of headphon es after having been already instructed they were required to press the red button only when they saw the red light flash across the light panel.The participant was instructed not to press a button for any other colour. The observer then set the machine to real test, selected selection reaction and pressed the clear colour button as well as the red. . There was no signal given to the participant as to when precisely the experiment would begin by the observer but they were told to be ready as soon as they saw the light the experiment had begun. The stimulus that required a reaction in the experiment was given 19 times and the experiment was only complete if the participant made no mistakes.At the end of the experiment a hand signal was given by the observer to the participant to let them know the task was over. Each reaction time was noted by the observer. Experiment 3 The participant stood on the test side of the machine and put on a pair of headphones after having been already ins tructed to press the button that corresponded with the colour they saw flash across the screen i. e. see greenish light, press green button. There was no signal given to the participant as to when exactly the experiment would begin by the observer but they were told to be ready as soon as they saw the light the experiment had begun.At the end of the experiment a hand signal was given by the observer to the participant to let them know the task was over. The stimulus that required a reaction in the experiment was given 19 times and the experiment was only complete if the participant made no mistakes. Each reaction time was noted by the observer. Experiment 4 The participant stood on the test side of the machine and put on a pair of headphones after having been already instructed to press only the red button when they heard the high frequency sound.The observer then set the machine to real test, simple reaction test and selected high frequency sound. There was no signal given to the participant as to when exactly the experiment would begin by the observer but they were told to be ready as soon as they heard the sound the experiment had begun. At the end of the experiment a hand signal was given by the observer to the participant to let them know the task was over. The stimulus that required a reaction in the experiment was given 19 times and the experiment was only complete if the participant made no mistakes.Each reaction time was noted by the observer. Experiment 5 The participant stood on the test side of the machine and put on a pair of headphones after having been already instructed to press the red button only when they heard the high frequency sound. The observer then set the machine to real test, election reaction test and selected all the frequencies. There was no signal given to the participant as to when exactly the experiment would begin by the observer but they were told to be ready as soon as they heard the sound the experiment had begun.At the e nd of the experiment a hand signal was given by the observer to the participant to let them know the task was over. The stimulus that required a reaction in the experiment was given 19 times and the experiment was only complete if the participant made no mistakes. Each reaction time was noted by the observer. Experiment 6 The participant stood on the test side of the machine and put on a pir of headphones after having been already instructed to press the button that corresponded with the frequency of sound they heard, i. e. high frequency= red button, middle frequency=green button and low frequency=yellow button.The observer then set the machine to real test, choice reaction test and selected all the frequencies. This time there was no hand signal given to the participant by the observer but they were told to be ready as soon as they heard the sound the experiment had begun. At the end of the experiment a hand signal was given by the observer to the participant to let them know the task was over. The stimulus that required a reaction in the experiment was given 19 times and the experiment was only complete if the participant made no mistakes. Each reaction time was noted by the observer.
