Abstract

The purpose of this experiment was to examine the widely used paradigm, the Stroop effect, and the difference in reaction time between three conditions. 357 university students were involved. A repeated measures design was used for three conditions: congruent, incongruent and non-colour. Participants were required to look at coloured words and name the ink colour, whilst ignoring the actual word. The results show that in the congruent condition, reaction time was faster and fewer errors …show more content…

The data presented shows that participants have a faster reaction time when partaking in the congruent condition, compared to the incongruent and non colour conditions. These findings support Stroop’s widely known theory of the stroop interference. By Stroop’s experimental findings, he has described that interference occurs by the automation of reading, where the brain automatically read the semantic meaning of word (e.g reading the colour blue and thinking of the colour blue). It is not an automatic process, when the brain needs to intentionally check itself and correctly identify the colour of the word. This explains the faster reaction time in the congruent condition, compared to the other incongruent and non colour condition. Sheibe, Shaver and Carrier’s theory can also be applied to this context as it is illustrated in the results that interference does occur via automatic …show more content…

Thought and effort must be applied when a child first begins to read, this is not an automatic process. However, as a student progresses onto reading fluently, reading become an automatic process. This process allows students to read topically, and perhaps not fully understand or pay attention to the content. Generally, society should be aware of this form of automaticity, thus striving for a more conscious and attentive way of reading.

  • The Crisis in Adolescent Literacy

    2250 Words  | 5 Pages

    With such high numbers of adolescents falling below basic in reading, illiteracy is a battle that must be fought head on. The largest dilemma with the struggle is the number of variations that cause adolescents to become reluctant, unmotivated or struggling readers. Fortunately, a large number of strategies exist to encourage and strengthen readers of all ages, proving that adolescence is not a time to give up on faltering students. Rather, it is a time to evaluate and intervene in an effort to turn a reluctant reader into an avid one (or near enough). Ultimately, educators must learn to properly assess a student’s strengths and weaknesses (Curtis, 2009) and pair them with the proper intervention techniques. If one method does not work, countless others exist to take its place.

  • The Stroop Experiment

    1068 Words  | 3 Pages

    Although correlation does not equal causation, we can conclude that similar cognitive processes, such as interference and automaticity, have influenced the results in our experiment. This can be expressed by the data and in identifying and saying aloud/reading a simple number compared to quantifying simple numbers. The cognitive load of reading familiar or smaller words is lower than that of counting, thus creating perchance a longer reaction time. In the experiment conducted in class as well as the one conducted by Stroop, the issue of divided attention may have been a great factor in interference or prolonged reaction time in the conditions. Psychological refractory period which states that the response to a second stimulus is slowed down by the first stimulus being processed; this can be a cause for the finding of increased reaction time when conflicting information is given. Attention may unconsciously be given to the less complex task, which is reading/identifying, and counting the main and more complex task may be interfered by the simpler stimulus. The expectation of having a longer reaction time when conducting the incongruent task was referenced back to the Stroop effect due to the similar implications of identifying and saying aloud the color presented in the print of the color descriptive word (Stroop,

  • Attentional Interference in Relation to the Stroop Effect

    614 Words  | 2 Pages

    The nature of the Stroop effect results as a consequence of automaticity. People have difficulty ignoring the meaning of a word because, through practice, reading has become an automatic process. The two main explanations accounting for the Stroop effect in the past have been cognitive attentional processes involved in learning, controlled and automatic. As previously mentioned, when a process is automatic (for example reading), it is not only faster; it also does not rely on other cognitive resources. Controlled processes, for example color naming, are slow and demand more attentional resources. The theory is that an automatic process cannot successfully suppressed without causing interference of a controlled process. The second explanation, relative speed of processing, argues that the two processes involved in color naming and word reading are accomplished in parallel, but that word reading is carried out faster, assuming that the faster process will then interfere with the slower ones such as color naming (Dunbar and McLeod, 1984 as cited in Mel, 1997)

    In a study done by V. S. Ramachandran and Zeve Marcus, seven synaesthetes and thirteen non-synaesthetes were tested on their personal effects of the McCollough effect (2017). Collectively, this study showed that the observations made could prove the possibility that the McCollough effect can take advantage of the color connections that synesthetes already possess to strengthen the effects.

    ...dering had an impact on performance while reading aloud and during a version of the Stroop task. During both experiments the researchers found mind wandering rates to be high and negatively associated with inaccurate responses across both conditions. In Stroop trials the researchers observed the slowest response times and highest error rates with incongruent trials (read word ‘red’ in green ink), however this was also the condition with the lowest amount of reported mind wandering. Increased mind wandering rates also forecasted slower reaction times; the findings suggest that processes associated with reading may correspond to those related to mind wandering.

  • Adolescent Illiteracy in America

    The causes of reading difficulties often arise because of learning disabilities such as dyslexia, poor preparation before entering school, no value for literacy, low school attendance, insufficient reading instruction, and/or even the way students were taught to read in the early grades. The struggles that students “encounter in school can be seen as socially constructed-by the ways in which schools are organized and scheduled, by assumptions that are made about home life and school abilities, by a curriculum that is often devoid of connections to students’ lives, and by text that may be too difficult for students to read” (Hinchman, and Sheridan-Thomas166). Whatever the reason for the existence of the reading problem initially, by “the time a [student] is in the intermediate grades, there is good evidence that he will show continued reading g...

  • Six Components of Reading

    1759 Words  | 4 Pages

    Reading is a complex process that’s difficult to explain linearly. A student’s reading capabilities begin development long before entering the school setting and largely start with exposure (Solley, 2014). The first remnants of what children are able to do in terms of reading are built from their parents and other people and object around them as they’re read to, spoken to, and taken from place to place to see new things (Solley, 2014). As kids are exposed to more and more their noises quickly turn into intentional comprehensible messages and their scribbling begins to take the form of legible text as they attempt to mimic the language(s) they’re exposed to daily.

  • My Philosophy Of Reading And Writing Curriculum

    2147 Words  | 5 Pages

    While I believe every child is a reader, I do not believe every child will be enthralled with reading all the time. All students have the capability to read and enjoy reading, but just like any other hobby, interest will vary from student to student. The students in my classroom will be encouraged in their reading, be provided with choice, taught how books can take you into another world but, my students will not be forced to read. This paper will illustrate my philosophy of reading through the theories I relate to, the way I want to implement reading and writing curriculum, and the methods I will use motivate my students to read and help them become literate.

    Overall, what happened in the experiment is that the boy test subjects did better than the girl test subjects on average. The boys had a higher overall average on the first and third test. Boy test subjects had times that clumped around 41-45 seconds. But in the boys line graph See Appendix’s 3-7) was more jagged than the girls line graph. Yet the girls had a much straighter line graph, which showed that they had a much tighter group of times. The girl’s data was centered on and around 41-45 seconds range. (See Appendix’s 11-15) The boys could have had faster times than the girls because the male and female brains are different. The boys’ times were clumped around 41-45 seconds, which is approximately the same as the girls, but

  • Literature review:Reading Comprehension

    1131 Words  | 3 Pages

    How can what we know about the development of readers inform reading comprehension instruction? Reading instruction typically starts in kindergarten with the alphabetic principle, simple word blending, and sight word recognition. Texts read by early readers usually include very little to comprehend. As children develop reading ability, they are able read more complex texts requiring greater comprehension skills. Separate and explicit instruction in reading comprehension is crucial because the ability to comprehend develops in its own right, independent of word recognition. The ability to read words and sentences is clearly important, but as readers develop, these skills are less and less closely correlated with comprehension abilities. (Aarnoutse & van Leeuwe, 2000) While no one would argue that word blending and sight word reading skills be omitted from early reading instruction, vocabulary and listening comprehension may be at least as important in achieving the even...

  • The Importance Of Reading Interventions

    895 Words  | 2 Pages

    Many students have a hard time when it comes to reading. There are many reading inventions that can help students out. Reading inventions are strategies that help students who are having trouble reading. The interventions are techniques that can be used to assist in one on ones with students or working in small groups to help students become a better reader. Hannah is a student who seems to be struggling with many independent reading assignments. There can be many reasons that Hannah is struggling with the independent reading assignments. One of the reasons that Hannah can be struggling with is reading comprehension while she is reading on her on. Reading comprehension is when students are able to read something, they are able to process it and they are able to understand what the text is saying. According to article Evidence-based early reading practices within a response to intervention system, it was mentioned that research strategies that can use to help reading comprehension can include of activating the student’s background knowledge of the text, the teacher can have questions that the student answer while reading the text, having students draw conclusions from the text, having

  • Disjunctive Reaction Time as it Relates to Complexity Level

    1166 Words  | 3 Pages

    This study was conducted to prove that reaction time increases as the level of complexity increases. Disjunctive reaction time was measured to eliminate subject reacting too early to the stimulus. Also make the tack more complicated and for subject to uses discrimination before responding to stimulus. Postman and Egan (1949) defines disjunctive reaction time as "two or more different stimuli are presented in random order…the subject is instructed to react to one but not to the other stimuli"(p 240). Rikli and Busch (1986) defined reaction time "as the latency from the onset of the visual stimulus to the depression of the microswitch"(p 646). Although a joystick was used to respond to the visual stimulus the same principle applies. For the purposes of this study both definition of reaction time were incorporated to facilitate proper measurement.
