Stroop Lab Report

In another study, five experiments were conducted to determine if coloring a single Stroop element reduced automaticity or slowed the processing of a color. The results demonstrated that indeed it slowed processing of congruent and neutral stimuli more than it slows processing of incongruent stimuli (Monahan, 2001).

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

Data were collected in September and November 2017 at the Elk Valley Preserve and Field Station in Banner Elk, NC. The preserve is located at 36°10'17.2"N 81°54'45.9"W, in Avery County in western North Carolina. The area is a mixed deciduous forest at an altitude of 1,127 m above sea level. Data were collected in early fall, during which temperatures average around 10-18 degrees Celsius. Summers in Banner Elk are typically mild, with temperatures averaging 21 degrees Celsius, and winters are cold and snowy, averaging near zero degrees Celsius. During the months of September and November there is an overall average precipitation of 12-25cm.

Controlled Vs Automatic processes: A modified version of a Stroop experiment using colour-associated and colour neutral words.

In the 1930’s, psychologists wanted to better understand how the brain processes presented information. To take it a step further, they wanted to see what happened when conflicting factors were presented and how the brain would process it. Would there be a delayed response? Would there be an error when giving the response? Psychologists were especially interested in how conflicting factors would inhibit the rate of impulse transmission in the nervous system (Eberle, 2012) and in 1935 John Ridley Stroop came up with an experiment to test the response rate of people when they were presented with conflicting factors.

In 1935, the Stroop Effect was first established by John Ridley Stroop. Research done by John Ridley Stroop emphasizes the processing of words that it has on the more studious challenge of naming just the ink color. The Stroop Effect is a proof of interference in the reaction time of an exercise. In the Stroop Effect, subjects are tested only on naming colors of incompatible words and of control patches (MacLeod 1991). Many tests can be distributed, all varied in the colors and words. Any color can be used; the same goes with any word being used. Subjects receive a time of how long it took them to read each test; where the subjects find a time difference between the different tests. When taking some of these tests, people may experience a mental sensation comparable to running in a swimming pool (Bower 1992).

In Stage 1, participants will classify pictures as quickly as possible as “male” or “female” by a button press. Each picture will be presented twice for a total of 20 trials. In Stage 2, participant will classify words as quickly as possible as “sexually attractive” or “sexually unattractive” by a button press. Each word will be presented twice for a total of 20 trials. In Stage 3, both pictures and words will be presented and, for half the participants, “male or sexually attractive” will share a response button while for the other half “male or sexually unattractive” will share a response button. Participants will perform 80 experimental trials (each stimulus will be presented four times) after 20 practice trials. Stage 4 will be a repeat of Stage 1 with the assignment of buttons to categories switched. Stage 5 will be similar to Stage 3 except those who had the button assignment of “male or sexually attractive” in Stage 3 now have “male or sexually unattractive” in this stage and vice versa. Each trial will consist of the fixation cross for 17 ms followed by the stimulus until a response occurs. The trials will be presented in a random order without

Over the years, several experiments and tests have been devised to study how the Stroop Effect could manifest itself in ways other than reading colored words. One such example was an experiment conducted by Shor who used auditory stimulus to provoke a Stroop-like event (1975). In his study, participants listened to a recording of an individual either with a deep bass voice or a high falsetto voice saying the words “high” or “low”

If the reaction time between the stimulus and the response increases when the colour of the word and the word itself are not the same, then the reaction time would decrease when the word and the colour of the word are the same. The Stroop effect is an observable way to view the difficulties the brain has in identifying conflicting sensory information. The conflicting sensory data that people are given will affect the time of their responses and impact on their ability to read the information out correctly and fluently.

In 1935, John Ridley Stroop conducted an experiment at George Peabody College for teachers in the United States. Stroop used 70 college undergraduates as subject in his experiment, he compared times for reading names of colours and naming colours themselves. The aim was to determine if the colour of the word affected the ability to read it. In the experiment, there was three different conditions. In the first condition participants were asked to read words as quickly as possible whereas participants had to name the ink colour in which each word were printed as quickly as possible in second condition. In a third condition (the incongruent condition), participants had to name the ink colour in which each word was printed, but in this condition the words themselves were colour names. For example, the word ‘GREEN’ was presented in the colour orange and you were required to read this colour instead of the word itself. Stroop found that the participants were much slower at naming the ink colours when the stimuli were themselves colours as (third condition), indicating that a possible explanation for the Stroop effect is that people quickly and automatically process the meaning of the word.

In this paper, the author want to know whether human genetic patents affect subsequent scientific research and product development. They use the administrative data on successful and unsuccessful patent applications filed with the USPTO and then link the exact gene sequences required for each application with subsequent scientific research and business investment data. By using these data, they found patented genes have more valuable prior to being patented than non-patented genes. They used two quasi-experimental approaches to text their hypothesis. In the end, they found both of the approaches suggest that on average gene patents have had no effect on follow-on innovation. “This evidence of selection motivates two

To view the influence of negative valence on performance, the emotional Stroop task has been utilised (Itkes & Mashal, 2015). The Stroop task involves participants naming colours of words whilst disregarding their background. The words used generally bear negative or neutral valence, and results propose that reaction times are slower to negative words in comparison to neutral words. (Itkes & Mashal, 2015) suggest that achievements on this role show a basic deceleration resulting from dangerous stimuli.

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.
