The Stroop Effect is widely known for its accomplishment and psychological relevance. The first experiment was conducted by James McKeen Cattel and Wilhelm Maximilian Wundt. They set out to explain and find why it take longer processing time when naming an object and/or color (Stroop, J. R., 1992). Being able to understand this cognitive process of Reaction Time (RT) allowed experimenters to devised procedures to further prove the concept. There are many reasons why RT and cognitive function interference can occur. It was termed The Stroop Effect after John Ridley Stroop who studied interference and published an article in 1935 outlining his findings. While, was not the first to propose this effect he did however, revolutionized the method in which interference can …show more content…
J. Ridley Stroop shifted away from the old way of determining interference from bonded stimuli. He proposed that interference could be measured by observing a pair of conflicting stimuli. These stimuli can be represented by the word “pink” which is the first stimuli. While the second stimuli is the ink “pink” which the word is written with. This has led to the introduction of the congruent condition and incongruent condition. The congruent condition is the stimuli which we can interrupt when we read the word “Red” and it is written in red ink. While, incongruent condition we would process the word “Blue” but it is now in red ink.
While the success of the Stroop task has been widely seen. It is very important to keep strong internal and external validity. In 1991 MacLeod, C. M. (1991) reviewed the validity of the Stroop task experiment and the Stroop effect. Of his findings, the theory automaticity came to light when looking at the Stroop effect. He explained that reading is an automatic process while naming colors is not. This
His experiment consisted on observing the different reaction times on a number of identifying processes, based on the interference demonstrated on the Stroop experiment (Windes 1968). Unlike the color identification in the Stroop experiment, this experiment resembles more to the experiment conducted in class, as it matched short words with number. The experiment yield results that expressed a faster reaction times to the words. This experiment showed that the effect observed in Stroop does not belong only to color identification but other features, like small words and
...We also saw that memory can play an important role too, but this is not yet clearly demonstrated. Moreover some studies reveal that the congruency (vs. incongruence) of the critical stimulus can also play an important role in awareness, a phenomenon called cocktail party effect. Such phenomenon makes clear that the relevance of the stimuli plays a key role in awareness and perception. The cocktail party effect is the phenomenon of being able to focus one's auditory attention on a particular stimulus while filtering out a range of other stimuli, much the same way that one can focus on a single conversation in a noisy room and yet be able to hear if someone calls out his name or other relevant stimuli (danger words for example). Still, sometimes we fail to perceive something that is happening right in front of us. It is easy to miss something you’re not looking for.
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.
...ce for increased activity in visual areas or the fusiform gyrus, which is connected with color perception. These results have shown that spoken words result in co-activation of color processing areas, but not visual areas connected with the perceptual process of color. Sadly, the conclusions don’t reveal which perceptual or cognitive processes might cause the difference with people with synaesthesia and the controls.
(Hart) Stanley Milgram’s experiment in the way people respond to obedience is one of the most important experiments ever administered. The goal of Milgram’s experiment was to find the desire of the participants to shock a learner in a controlled situation. When the volunteer would be ordered to shock the wrong answers of the victims, Milgram was truly judging and studying how people respond to authority. Milgram discovered something both troubling and awe inspiring about the human race. “Since they were first published in 1963, MIlgram’s sensational findings have been offered as an explanation for mass genocide during the Holocaust and events such as the My Lai Massacre in Vietnam and the torture of prisoners in Abu Ghraib prison”(Perry 223-224). The way Milgram was able to control the experiment shows how the human race can crack under pressure and obey orders, no matter the consequence. Although, not everything was as it seems when it came to the results of the findings. As Milgram used actors to portray the “victims” in the experiment, so no one was truly being tortured. Milgram wanted to show that pressure can get to anyone, in any situation.
The Ground Effect (or Wing in Ground Effect) is a natural phenomenon that occurs due to vortices caused by a difference in pressure between the two sides of a wing. This effect can be very dangerous to inexperienced pilots, but can be utilized by creative engineers.
Muller-Lyer illusion is one of the most studied perceptual illusions experiment in cognitive psychology. The illusion experiment was created by Psychiatrist Franz Carl Muller-Lyer in 1889. The Muller-Lyer illusion reveals that when three horizontal lines with the same length are presented together. The first line has two outward wings at its end; the second doesn’t have wings; and the last line has two inward wings at its end. Muller-Lyer illusion says that the line with outward wings looks longer than the line without wings, and the other line with inward wings looks shorter than the one without wings. In our CogLab experiment, it is designed to have only a line with outward wings and another line that has no wings showing to the participants; their task was to choose which line is longer than the other in the experiment. In this experiment, the constant stimuli experimental method will keep the length of the line with outward wings constant throughout the experiment. The result will tell us participants’ judgments of physical length may be deluded by the presence of outward wings. Participants tend to perceive that the line with wings looks longer than a line without wings. (CogLab, Muller-Lyer Illusion, Cengage Learning)
The CogLab on Simon effect focuses on the visual system, more precisely, processing sensory information and producing an appropriate motor response. Specifically this CogLab relates to chapter three which is about visual perception. Now after participating in the study and learning more in depth about the Simon effect, I have gained a better understanding about natural tendency in visual processing, and how the location of an object can affect your decision making skills. In addition, after looking more in depth at the original study, I understand how researchers conduct experiences for cognitive psychology by focusing on the cognitive processing and how it affects our visual

He suggests that when analyzing colors and their role in brain processes, we are misinterpreting the way it should be understood. When we speak about these sensations that are synonymous with the brain processes, it should be said as “There is something going on which is like what is going on when ____,” (149). In the case of seeing red as mentioned before, the statement would appear as “There is something going on which is like what is going on when I have my eyes open, am awake, and there is an emission of red cast from an object, that is, when I really see red." Ultimately, I do not believe this response is an adequate answer to the objection. It appears that Smart is merely altering the linguistic nature of the question rather than providing a solution to the problem. This “something” neutralizes the difference between a brain process and a sensation without giving a sound reason as to why or how they would be considered identical rather than
In their pieces on the Smurfette principle, Pollitt and Ellis both discuss the idea that gender representations have intense effects on the children who absorb certain types of popular entertainment. Although we are hesitant to accept it, we are all influenced by the media in a very powerful way. Whether it be through TV shows, billboards, movies or the news. One thing that we commonly wonder about is if the adult female population is as influenced by the stereotyped gender roles present on TV or are we shaped at a young age and carry that perspective with us throughout our lives. This Smurfette principle has been around for almost two decades. It was introduced by Katha Pollitt and is unfortunately still present in our current 21st century.
As Director of Human Resources for People, people who need people.com, I have created the following training proposal which will include common problems that occur when managers complete performance reviews and suggestions for supervisors on how to eliminate or reduce these problems.
Although there was some criticisms about the above experiment, Craik and Tulving performed more experiments each time refining the D.O.P. model. There were thoughts that the structural tasks were easier and not as much time had to be spent on them therefore people did not have as long to look at those words and could not study them like the other tasks. Craik and Tulving then made the structural task take equally as long as the other tasks. The results remand the same as the previous experiments. Craik and Tulving also originally started with five tasks, but then narrowed it down to three to avoid a ceiling effect. The self-referent task was later added to model by Rogers.
Although, there was no field called cognitive psychology during the 19th century, Donders and Ebbinghaus were referred to as cognitive psychologists because both of their experiments dealt with the studying of the mind. Donder’s experiment focuses on a person’s Reaction-time in order
