Stroop Effect Lab Report

The Stroop effect is demonstrated by the reaction time to determine a color when the color is printed in a different color’s name. Participants respond slower or make more errors when the meaning of the word is incongruent with the color of the word. Despite knowing the meaning of the word, participants showed incapability of ignoring the stimulus attribute. This reflects a clear instance of semantic interference and an unfathomed failure of selective attention (Stroop, 1935).

An interesting challenge arises when a task such as color naming is identified as both controlled and automatic, by varying the other task involved. Color naming is identified as a controlled process when the other task is word reading, but as an automatic process when the other task is shape naming. Cohen, Dunbar and McClelland (1990) proposed an alternative explanation of the Stroop effect, which does not distinguish between automatic and controlled processing. Instead, they proposed that automaticity is a range, and that Stroop interference depends on the relative degree of learning the particular tasks, not on processing speed.

The Stroop effect was tested on four different tasks. Nineteen Queens College students were recruited by flyer, and each were assigned to a word reading task, color reading task, color inhibition task, and word inhibition task. They were timed using a stopwatch function on a cell phone, to name the color, or word to the quickest of their ability. In the order from longest reaction time to shortest: inhibition color naming task, color naming task, inhibition word reading, and word reading. This study shows that people can read words more quickly than they can name colors, and that inhibiting an automatic response to color/word tasks will take longer to do than tasks that do not involve inhibition.

The Stroop experiment by J. Ridley Stroop in 1935 was performed in order to analyze the reaction time of participant’s stimuli and desired results while also obtaining a collective result of color interference and word reading(Stroop, 1935; Lee & Chan, 2000). In the experiment three forms of the test were given, the first consisting of color patches, the second had the color words printed in black and the other was an incongruent test beaming the color did not match the color word

The aim of this experiment is to study autonomic processes by replicating the previously carried out Stroop effect by using numbers. A number of 180 random participants aged in between 18-89 were recruited to participate in this experiment. Participants were presented with a stroop experiment task sheet which consists of three parts which was the control, congruent and incongruent conditions. Time was taken and recorded for each participant to say out the number of stars in the control condition and to say out the number of numbers in the congruent and incongruent conditions. Based on the results, participants took a considerably longer time to say the number of number in the incongruent condition than in the congruent condition.

Abstract The lab test that yielded the Stroop Effect was designed to help us understand how the brain processes information. Experiments that produce the Stroop Effect require the brain to deal with potentially conflicting information. Stroop task produces response conflict because we have a prepotent tendency to process words over retrieving names of colors. It requires the ability to ignore irrelevant textual information and inhibit oneself from reading the words aloud.

We go throughout our busy lives, multitasking with many objects that come across us. We tend to text and drive, eat and watch television, and even walk and chew gum at the same time. We need to get a better understanding of our brain and how it is able to do many things at once. John Ridley Stroop, an American psychologist researched in the area of cognition and interference. The area of psychology that the Stroop Effect is grouped in is cognition. Cognitive psychology includes the study of memory and thinking, conscious processes, problem solving, creativity. This is what makes humans brain activity differ. In the field of cognition, many experiments

The results revealed significant mean time differences in reading the words and naming the colors. This confirms that interfering stimuli affect cognitive processes. Thus, proving both hypotheses to be correct. THE STROOP EFFECT EXPERIMENT 3 Introduction The Stroop effect is a test to demonstrate how our brain manages and process conflicting stimuli.

The Stroop Effect is a popular phenomenon used throughout experimental psychology. It detects interference and inhibition by having participants’ naming at the color ink presented on paper or index cards and not being conflicted by other stimulations such as the written word. It is measured by the delay in response time.

However, automatic processes are hard to amend once learnt. Kahneman proposed his capacity/resource allocation model in 1973 (see Figure 1): [IMAGE] Figure 1 This model could provide an explanation for the Stroop Effect as the visual interference of the conflicting colour could be described as a momentary intention (a voluntary shift of attention). This is because the participant has to force his/herself to read the word and not say the colour of it. This therefore means that, according to Kahneman, the central processor has trouble deciding between tasks (in this case, between reading the actual word or the colour of it).

When we want to learn something new; we can have difficulties in processing the information. Stroop (1935) the Stroop effect is an example of a link between repeated and controlled processes. The purpose of this experiment was to replicate two of the three stimulus Stroop did in his original experiment, and to investigate the difference in reaction time between the congruent and the incongruent conditions. There were 20 participants involved, 13 female and 7 male students. A independent measure design was used for the two conditions: congruent and incongruent. We called in one student at the time. Whether they chose the congruent or the incongruent list was random. If they randomly chose the congruent task they had to say the word

The Stroop Effect is the type of interference of different and confusing messages that are being send to and from the brain. It was named after John Ridley Stroop who first reported it in a journal of psychology in 1935.

Red, Green, Purple, Blue! Neurologists test the brain’s cognitive skills by trying to determine the text of the word the color is printed in; in which they have to differentiate the color from the meaning of the word. The subject is shown a color, and it will take the person longer to identify the color of the word, if the word is in an incongruent word color. This cognitive phenomenon is more commonly known as the Stroop Effect. The Stroop Effect is a study that lead to the occurence where objects of incongruent context and word display are used to find the reaction time it takes to determine the context of the word. The original way that is used to test the Stroop Effect is by printing a name of a color, in a

J.R. Stroop conducted an experiment in 1935, where he studied the difference of automatic and controlled processing through his experiment called the Stroop Effect . Automatic processing can be defined as an implicit way of thinking that is unconscious, while controlled processing is intentional. The experiment dealt with Stroop giving the participants two list in different conditions. While the participants read the lists, they were told to read them as fast as possible. In the first condition the people had to read the ink in which the word was written in, for example the color would be red and the word would be “RED”. The second condition was similar except that word and color did not coincide, for example the color would be green but the word would read “PURPLE”. Their processing would be affected during the second condition, and they would have more trouble recognizing the color “green” when the word they read was purple.

We are replicating J.R. Stroop’s original experiment The Stroop Effect (Stroop, 1935). The aim of the study was to understand how automatic processing interferes with attempts to attend to sensory information. The independent variable of our experiment was the three conditions, the congruent words, the incongruent words, and the colored squares, and the dependent variable was the time that it took participants to state the ink color of the list of words in each condition. We used repeated measures for the experiment in order to avoid influence of extraneous variables. The participants were 16-17 years of age from Garland High School. The participants will be timed on how long it takes them to say the color of the squares and the color of the words. The research was conducted in the Math Studies class. The participants were aged 16-17 and were students at Garland High School. The results showed that participants took the most time with the incongruent words.
