Experimental Psychology: The Stroop Effect

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).

A Replication of the Stroop Effect Kimber-Ann Cook Broughton High School 3/26/08 Ms. Greene IB Psychology SL 1, 738 Abstract The Stroop (1935) effect is the inability to ignore a color word when the task is to report the ink color of that word (i.e., to say "green" to the word RED in green ink). The present study investigated whether object-based processing contributes to the Stroop effect. According to this view, observers are unable to ignore irrelevant features of an attended object (Kahneman & Henik, 1981). In three experiments, participants had to name the color of one of two superimposed rectangles and to ignore words that appeared in the relevant object, in the irrelevant object, or in the background. The words were congruent,

An Examination of the Stroop Effect among College Students Esmeralda Fierro Dixie State University Abstract 250 word summary of the paper One paragraph only Do not indent the paragraph An Examination of the Stroop Effect among College Students 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 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

In Stroop’s (1935) interference article, it was discovered that there is more interference in color naming then color reading. The experiment described in the article tested whether there was more interference from words or from colors (Stroop 1935). Two tests were administered each with a separate control. The RCNd test determined how fast one could read color names where the color was different from the color name while the NCWd test determined how fast one could name colors where the color was different from the word on the page. The mean time for 100 responses increased from 63.3 seconds on the RCNd test to 110.3 seconds on the NCWd test or an

The aim of this experiment was to basically analyze how fast the brain can perceive color and describe words simultaneously with the Stroop Effect theory. The Stroop Test is also done to determine new findings on the human’s brain automaticity and how it processes certain functions. In reference, to the independent and dependent variables involved, the independent variable in this experiment would be the color word followed by the conflicting color and the dependent would be the time that it took for the applicant to make a decision. At the conclusion of the lab, applicants were to record their results as well as the group data results and new findings of how the brain functions under certain processes. However, the age differences and the reading comprehension levels of the applicants involved, may have also caused an error due to the lack in understanding of the of time intervals in the ending data.

Testing of the Stroop effect in colour-associated words and neutral words Abstract Study examined the Stroop effect in words which are not colours, but represent related object connected to certain colours and whether that would yield similar or the same effect as the classic Stroop study. Previous studies such as Stroop's (1935)

We often tend to live our everyday lives without paying much attention to the factors that contribute to our every movement and function. Have you ever wondered what triggers your brain to complete simple tasks, such as reading road signs, or knowing how to follow a guided set of instructions? John Ridley Stroop became specifically interested in the part of the brain that measures selective attention [1]. Oftentimes, in order to maintain balance, the brain will carry out the action that is most common and easy and will stop the action that will take more work and effort. The process explained in the previous sentence is known as inhibition, and it regularly occurs in our minds [2]. Stroop gave participants a list of colors, such as green,

In the Stroop task 8 college student participants from a cognitive lab course. Two participants were males and the remaining 6 participants were female. Using a computerized program Cedrus SuperLab 4.5 the participants were tested in the Stroop Task. The participants were asked to identify four colors, blue, green, red or yellow. In addition, participants were also asked to identify the names of the colors they saw by pressing a corresponding computer key with their middle and index fingers, D for red, F for blue, J for green, and K for yellow. Our experiment was conducted in two phases a practice phase and a testing phase.

At the beginning stages, reading takes some effort, and conscious attempts at sounding out the letters of each word. As people practice reading skills, they finally learn to read without trying. When a behavior or skill no longer requires direct effort to be completed, cognitive psychologists say it is automatized (CogLab). Automatization is fascinating because it is an important part of daily life. Most people perform a numerous of automatized behaviors quickly and effortlessly. People often think they can multi-task, but classic research by J. Ridley Stroop shows differently. Stroop (1935) demonstrated that if someone is reading information, and other conflicting information is added, the rate in which a person will read the information would slow down. Stroop presented his participant with 100 words, each word spelled out a color, but the ink of the word was different from what it spelled. His participants were asked to report the color of the ink the word represented. The interface of conflicting color stimuli upon the time for reading 100 words caused an increase 2.3 seconds over the normal time for reading the same words printed in black (Stroop, 1935). Stoop found that participants performed slower to read the color of ink when the ink was used to produce color names different from the color of the ink. For example, the participants were slower to identify red ink when it spelled the word blue. The reasoning for this experiment is to test the Strop effect. The experimental hypothesis is that the time of reading the incongruent list of digits will be longer than that of the congruent list of

Khadiga Zagha 10/21/15 Psychology Per. 6 ~Intro of IA~Stroop Effect~ 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

An experiment in demonstration of this was conducted by J.R. Stroop (1935) who introduced the color naming experiment known as the Stroop Effect, where he showed that when people have to name words in different printed color it interferes with their abilities to read them efficiently. Stroop asked participants to read words as quickly as possible in one condition where words were printed in all black and in a second condition where participants had to name the ink color in which each word was printed as quickly as possible. Stroop found that the participants were much slower at naming the ink colors when they had the distracting stimuli of having it in a different color, indicating that a possible explanation for the Stroop effect is that people quickly and automatically process the meaning of the word. This would therefore interfere with the ability to process a color effectively in the second condition. In conclusion, Stroop stated that conflicting stimuli to a certain task interfere with with the person’s ability to complete it efficiently (J. R. Stroop 1935). The study is worth replicating as it shows the limitations of an essential human ability that is heavily relied on. The aim of our experiment is to investigate the effect of two contradicting stimuli on the time it takes participants to name them

In testing for the Stroop Effect, three conditions were used in a pseudo-randomized way. One such condition involved participants naming the color of a word, when the word spelled out the direct opposite of that color. For example, when a participant was presented with a green colored word, the word actually spelled out “blue”, and vice versa. This condition was called the direct conflict list. A

Psychology has been strategically split into three levels of analysis, biological, cognitive, sociocultural. Each one specific to different process in our brain and its functions. The brain remains a mystery but throughout history researchers big and small have taken it into their own hands to help us understand how it works. For this internal assessment a study pertaining to the cognitive level of analysis will be replicated. The study was originally conducted by J. Ridley Stroop in 1935 under the name : Studies of Interference in Serial Verbal Reactions. The same study is commonly known as the Stroop Effect. The aim of this study was to identify to what extent does conflicting stimuli affect verbal serial recognition. For the purposes of
