Stroop Effect

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).

This experimental research was conducted in a laboratory setting. The necessary equipment for each group included a stack of twenty squiggle cards, a stack of twenty word cards, and a stopwatch. On the back

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 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.

The Stroop test consisted two major posters of word lists: Incongruent list and Neutral list. Each poster included 20 words in 2 columns of 10 words each. All letters were stenciled, capitalized and 1 ¾ inches high. Both incongruent and neutral words were listed on the 56 x 71 cm posters Stopwatch with 0.01-second accuracy was used to time to measure how long participants took to read both incongruent and neutral word lists, which is a dependent variable for this experiment.

The trials for each of the six conditions were presented in a random order. The experimenter controlled for differences among participants by having them set their own equiluminant point for the cue stimuli and eliminated luminance differences by embedding the stimuli in a random luminance noise. The experimenter also controlled for outliers by eliminating response

The order of these trials were shown at random. All stimuli were shown for 200 milliseconds.

final experiment Johnson, Hollingworth, and Luck tested to see whether whole-array stimuli would generate a binding deficit. The main alteration that researchers used was color and shape rather than that of the use of color and orientation. This study used a 3-digit number that each participant was to repeat aloud during experiment. Displayed for participant was a stimulus randomly assigned a positon or centered on the display screen. A small time allotment was given for participants to respond. Findings suggest that overall accuracy was highest within the whole display in the color only condition. Johnson, Hollingworth, and Luck conclude that having a multitude of objects to focus on, memory performance remained near 65% correct in the dual-task binding condition. (Johnson, Hollingworth, & Luck, 2008)

Each experiment had the same procedure among different participant groups. The participants in the first experiment was thirty-one undergraduate or graduate student from the University of Cambridge. For the second experiment, fifty-nine people were recruited by community advertisement. And in the last experiment, twenty-seven survivors from fatal motor vehicle accidents, who developed PTSD (PTSD+) or never suffered from PTSD (PTSD-), were recruited through newspaper advertisements and from local clinics. In each trail of the experiment, the participants need to complete a storage task, which required them to remember 4 to 7 words, and an operation task, which asked them to count the number of a specific shape before and after the present of words. The words and shapes was shown over a neutral or negative background. In each trail, the participants need to complete the task 6 times. In each task, over a background image, four shapes popped up with 250ms each, and a word would appear for 350ms, and the other three shapes would show up with 250ms each. After that, the background image disappeared and the participants need to answer a question about the number of a specific shape they saw. After repeat this for 7 times, the participants were asked to write down all the words they saw in the order they presented. The percentage they correctly recalled was recorded. In each experiment, the independent variables were the negative background

The purpose of this study was to learn about how students process numbers and quantities. At the start of the experiment, the student researcher asked me to familiarize myself with the experimental set-up by doing a few trial runs. I was asked to press the spacebar every time something appeared on the screen. Then, for the actual experiment, I was instructed to stare at a fixation point while resting my chin on a chinrest. On either side of the fixation point was a small circle. I was told that a number may or may not appear on the screen, but if one does appear, I was told to just ignore it. Then, one of the dots may suddenly be filled in. If and ONLY if a circle is filled in, we were asked to immediately press the spacebar. If no circles were filled in, we were not supposed to press the spacebar. We had to repeat this

The Stroop Effect experiment generalized selective attention and how it affects our everyday thinking. The experiments main focus depicts how selective attention impacts our everyday lives and how efficient/ effective our thinking process can be. It is a classical phenomenon well versed in experimental psychology. The stroop tasks describes a task in which participants must identify color names printed in an opposing color of the presented word and read color names where the color of the print is the same as the word.

The experiment included a total of 151 participants (42 male; 109 female), all of which are enrolled in a Griffith University second year Psychology course.

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

Participants and Apparatus. 23 NYU students, taking lab in human cognition, received course credit for their participation in the experiment. The experiment was administered on standard PC’s or Macintosh computers over a single class period.

It has been proposed that automatic processing, unlike controlled processing, has a lower cost on the resource pool which is beneficial when process several channels of information. This could however have a cost on completion of some tasks because overlearned actions by their nature are difficult to cognitively control. This quantitative study focuses on whether automatic processing relating to overlearned actions can interfere with correctly identifying the colour ink of a printed word. The results showed that naming the ink colour took longer when the word was colour related.
