Effect of Word Combinations on Accuracy and Response Time
Effect of Word Combinations on Accuracy and Response vizorChristina M KaribianAbstractThrough tabu our daily lives, we tend to expose legion(predicate) behaviors that atomic number 18 considered self-acting. The Stroop heart has been replicated numerous condemnations to help study the phenomenon of self-moving behaviors, since John Ridley Stroops true findings. The goal of this sample was to study the reception clock snip and the true on congruous and in harmonious pass develop of honor combinations. The harmonious lyric poem were of color spell out, that were displayed in that same color (e.g., the word verdure was pen in the color green). The in appropriate haggling were of colors spelt out, that were non displayed in the same color (e.g., the word green was compose in red. During this try, 19 lowgraduate male and female college students ( intermediate age of 22.5 days old) participated as part of a scoreroom requirement. separately actor was abant hroughd an management weather sheet which say them to perform a Stroop task on a computer to measure their reply metre and true statement for the congruent and incongruent wrangling. Based on the results, the role players had a signifi commodetly fast-breaking answer m with the congruent dustup than the incongruent words. However, their accuracy of recognizing congruent words had no significant difference than incongruent words. in that respectfore, these results can relate to Stroops original research. It can be said that the learned automated behavior of edition the diametrical word combinations, does non interfere with the task at hand, besides does interfere with the reply era.TitleDuring our eachday lives, we display many behaviors that cognitive psychologists considered to be automatic. An automatic behavior is a sign of skill that does not need direct interaction to perform the task at hand. some(prenominal)(prenominal) good examples of these types o f behaviors are reading and writing. Cognitive psychologists like to study the properties of these automatic behaviors by creating spaces where an automized response will conflict with the researchers desired behavior. This type of situation can be studied by the Stroop effect. The Stroop effect was an sample primitively conducted by John Ridley Stroop in 1935. During this experiment, Stroop studied the relationship between the haphazardness and reception prison term of a task. This phenomenon that Stroop studied has been hired in divers(a) ways since his original experiment to measure and assess many different cognitive abilities in human beings.After Stroop conducted his study, he wrote an article to pardon his findings. In that article, he talked about devil experiments which he conducted to study this phenomenon. He believed that the reaction clock between the response and the stimulus would growing when the word and the color of the word itself were not the same. He overly believed that the reaction time would decrease when the color of the word and the actual word were the same (Stroop, 1992). During the stolon experiment, Stroop characterd 70 undergrad college students as his participants the second experiment consisted of coke college students. When compared to just reading the word written, Stroop found that it took the students a longer time to complete the task of saying the correct color that the word was written in, preferably of reading the actual word (Stroop, 1992).Ben A. Parris, Dinkar Sharma, and Brendan Weekes are a grouping of researchers that conducted a study based off of Stroops findings. They wanted to strain how interference, relating to the Stroop effect, would materialise when only specific garners in the word were dark-skinned. The goal of their experiments was to be able to identify if interference would be larger when the sinister earn in the word was in the OVP (optimal viewing position- position where wor d comprehension is the shor raise). There were 48 college students used for the first experiment and 20 college students for the second. The results of this experiment was that the Stroop effect was seen when the colorize letter was to the left of the middle of the word. When the non-white letter was in the middle of the word, at that place was a great reduction in the interference. Yet, in both these experiments, the only time interference was at its great was when the colored letter was at the OVP (Parris, et al, 2007).Talia Konkle and Aude Oliva conducted a study sympathetic to the Stroop task, to test whether or not a persons previous familiarity with the size of an objective lens in the real-word was accessed automatically. Three experiments were conducted overall to study this, they used 34 participants in the first, 19 in the second, and 17 in the third. They visually presented two objects that were familiar to their participants in different sizes on a cloak. The co ngruent conditions were two images of objects on the projection sieve reflecting real-world sizes (e.g., a grape and a horse, the horse being the bigger image). The incongruent conditions were two images of objects on the screen that did not reflect the real-world sizes. In the end, the reaction time for the incongruent conditions were found to be longer than the congruent conditions, which was expected. In the third experiment the participants were taught which colored blocks would represented large or miniature objects. Then the images of those colored blocks were shown on a screen, with identical congruent and incongruent conditions, as distant as sizing, as the otherwise experiments. These participants did not display any Stroop effect during this experiment (Konkle and Oliva, 2012). The current experiment was done to measure the response time and accuracy of word combinations on undergraduate college students at Queens College. This experiment was done to test if the reac tion time for the congruent condition would be significantly faster than the reaction time for the incongruent condition. It was also believed that the accuracy for the congruent condition will be significantly more(prenominal) accurate than the incongruent condition.MethodParticipantsThe participants in this experiment consisted of 19 undergraduate college students at a four year school there were 15 females and four males. The fuddled average age for these participants was 22.5 years old, with a standard deviation of 3.2 years old. All of the participants were familiar with using a computer, keyboard, mesh, and a mouse. They were not compensated for their time because it was a required class experiment. The participants all had normal to corrected vision and had normal color vision. They also had fine motor skills at heart normal limits.Apparatus (Materials/Stimuli)The materials that were used during this experiment was a Dell desktop personal computer with internet access, r ail on Microsoft Windows to perform the Stroop test on. A mouse was used to navigate around the computer, as well as a keyboard to enter the responses for the test. There was a flat desk which the computer was on and a chair for the participant to sit in while taking the test. to each one participant accepted an instructions sheet telling them step by step what mandatory to be done by them during the experiment. experimental DesignThis experiment was a within-subjects design. The manipulated variable was the color that the congruent and incongruent words were displayed in. There were two measured variables for this experiment. One being the reaction time for both congruent and incongruent words, which was measured in milliseconds. The other was the accuracy of the response for both the congruent and incongruent words, which had a scale of accuracy was 0.00-1.00.ProcedureThis experiment started off with the participants all sitting in desks in a classroom, where an instruction she et was handed out to them. The sheet was explained to them and therefore the experiment had begun. Each participant took turns going into smaller separate rooms where a integrity computer was. They were to work alone during this experiment. The only thing that needed to be brought into this room was a pen or pencil, their instruction sheet, and a results sheet to record their data. The instruction sheet tell the participant to open up the internet and go to the website, http//psych.hanover.edu/JavaTest/CLE/Cognition/Cognition.html. After being brought to this website, the instructions told the participant to select Stroop Experiment, which then explained what was being measured. The sheet explained that they will be comparison the reaction time, in milliseconds, between two conditions, congruent words and incongruent words. It also described what congruent and incongruent words were as much(prenominal) congruent words (color and word the same) and incongruent (color and word di fferent). The instructions then told the participant to scroll down and click on begin experiment.The conterminous set directions on the instruction sheet were to fix the settings once the internet loaded the main black screen. The first trial settings were to be changed by clicking on the correct items listed on the sheet. They were to be changed to the following condition = congruent words, colors used = red, green, blue, and yellow, respond to color, do not limit stroop time, emergence of words in condition = 25, font size = 20, location of word = in the center. After fixing all these settings, the instructions then directed the participant to press the space bar to start. It also stated in the instructions to watch for the word which would appear in the center of the screen and to use the keyboard to respond. The words that appeared in the middle of the screen were colors spelt out, that were displayed in that same color (e.g., the word green was written in the color green). T hese were the congruent word combinations. Therefore, the instruction sheet explained to use the response keys for those words to the color of font they are for r for red, y for yellow, b for blue, and g for green. After completing the trial for congruent words, the participants reaction time, and accuracy results were shown on the screen. The instructions directed the participant to record their reaction time and accuracy in milliseconds.After recording their data, the instructions then directed them to close the window back to the main black Stroop Experiment screen and conduct the second trial for incongruent words. E genuinelything else stayed the same as far as settings go. Then the instructions directed the participant to select done at the bottom of the screen to start the second trial. It also reminded them that in this condition, the words and the colors were different and to respond to the color they saw, instead of the word they were reading. Once this trial was over, the instructions directed the participants to record their reaction time and accuracy.After completing both parts of this experiment, the participant closed out the internet and left the separate computer room for the next participant. Each participant was told to write their results on the same sheet of paper. This sheet was separate off into four separate columns so that the results could be organized under congruent and incongruent reaction time and accuracy. Then a within subjects t-test was conducted at an alpha level of 0.05.ResultsThe mean reaction time to substantiate the congruent condition was 931.80 milliseconds with a standard deviation of 261.31 milliseconds. The incongruent conditions mean reaction time is 1204.86 milliseconds. The mean accuracy for the congruent condition was 0.99 with a standard deviation of 0.01. The mean accuracy for the incongruent condition was 0.93 with a standard deviation of 0.14. The congruent condition had a significantly faster reaction time than the incongruent condition. The t-test with 18 degrees of freedom is equal to a t-value of 4.42, which is greater than the critical value of 2.88. T(18) = 4.42 2.88, p DiscussionIt was originally predicted that the reaction time for the congruent condition would be significantly faster than the reaction time for the incongruent condition. It was also believed that the accuracy for the congruent condition would be significantly more accurate than the incongruent condition. This was predicted because reading is something that we do every day of our lives. Therefore, the behavior of reading comes automatically to us without us having to really think about the task. In relation to this experiment, reading the word and see it displayed in the same color, made it easier for the participants to be accurate in their reaction, as well as be swift about it. Whereas, when the participants were asked to respond to the color, and not to the word they were naturally inclined to read, it to ok longer for them to respond, but did not brass to effect the level of accuracy.What was done in this experiment relates to Stroops original experiment. This is because he believed the reaction time between his participants response time was going to increase when the word and the color of the word itself were not the same (Stroop, 1992). Which is also what was believed to be true in this experiment, and was found to be true. Stroop also believed that the reaction time would decrease when the color of the word and the actual word were the same. Which is what this experiment showed to be true as well. The results between the two experiments, even though they are about 80 years apart from each other, have very similar findings. They are also similar because both experiments used undergraduate college students as their participants. Using similar participants can help create more control and reliability of an experiment.In the study conducted by Parris, Sharma, and Weekes, they want ed to test how interference occurred when only a specific letter of the word was colored, instead of the whole thing. Their goal was to identify a larger interference when the colored letter was in the OVP. Since they tested this theory by moving the colored letter in the word in different directions, the results showed that the Stroop effect was then seen. It was seen when the colored letter was to the left of the middle of the word. It was also seen when the colored letter was in the middle of the word, but there was a significant reduction in the interference. Yet, in both of their experiments, the interference was at its greatest when the colored letter was at the OVP (Parris, Sharma Weekes, 2007). This relates to the present experiment because it shows that the most interference was when the OVP was the colored letter making the participant react slower in wander to accurately state the color, instead of the word written. The participants and results from this study are simi lar to the those from the present experiment. Both used college students, and both found interference in relation to our automatic behavior.In Konkle and Olivas study, they conducted a similar Stroop task as well. They wanted to see their participants reaction time and accuracy when identifying the size of an object in the real-word. They visually showed their conditions to their participants, like the other experiments talked about. Since their findings showed that the reaction time for their incongruent conditions was longer than their congruent conditions, it also shows signs of interference (Konkle and Oliva, 2012). They too used college students and had findings similar to all the other experiments, which again, could show that using similar participants for similar studies can be beneficial.There were a couple procedures that could have been improved throughout this experiment to create more control, internal validity, and reliability. or so participants know how to type on a keyboard without looking at the keys, whereas there are other who dont. This causes a threat to the reaction time, as well as accuracy. Some people might have taken longer responding because they needed to look down at the keys. It can pose a threat to accuracy because someone might have pressed the wrong key by not looking when they were not that familiar with the keyboard, as other whitethorn be. What could have been done in order to try and make this as equal for each participant as possible, was to have them still use the computer monitor, but only have four buttons on the desk for them to use to respond. If this was how the experiment was conducted, the settings on the computer would need to be fixed front to the experiment. This too could have caused less control during the experiment. Some people may have entered the wrong setting in the beginning and did not ensure it.Since it was found in this experiment that the reaction time for the congruent words was significantly f aster than the incongruent words, it can be connected to a persons response time during other activities. For example, if all of a sudden the colors to the traffic lights were changed, and we were taught what the new colors represented, most people would have a slower reaction time responding to the action the lights now incur. These findings show how our well-learned automatic behaviors can be inhibited when it naturally wants to occur, if our brain is working against it.ReferencesKonkle, T., Olivia, A. (2012).

This table provides the average reaction time in milliseconds, as well as the standard deviations for the congruent and incongruent words. This table also provides the average accuracy and standard deviations for the congruent and incongruent words. These results were calculated from the separate results collected from each participant. A within subjects t-test was conducted at an alpha level of 0.05.Figure 1. This figure shows the average reaction time in milliseconds relating to the congruent and incongruent words. It shows that the average reaction time for congruent words was 931.80ms. It is also shown that the average reaction time for incongruent words was 1204.86ms. Displayed on this graph shows how incongruent words had a longer reaction time than congruent words.Figure 2. This figure shows the average accuracy relating to the congruent and incongruent words. It shows that the average accuracy for congruent words was 0.99. It is also shown that the average reaction time for incongruent words was 0.93. Displayed on this graph shows how congruent words had an average closer accuracy than incongruent words.
