ABSTRACT
This Psychology Internal Assessment will replicate J. Ridley Stroop’s (1935) Stroop Effect test. The aim of the experiment we will be doing was to investigate whether visual interference affects the cognitive processing speed (in seconds) in naming colored words. The research hypothesis states that the mean time to identify the

The Stroop Effect by J. Ridley Stroop will be replicated to investigate whether visual interference affects the cognitive processing speed in naming congruently and incongruently colored words. To further understand the results of the participant effects of the Stroop Test, this internal assessment will also look into Morton and Chambers’ (1973) Speed Processing Model, Shiffrin and Schneider’s Automaticity Model (1977), Cohen, Dunbar and McClelland’s Parallel Distributed Processing Model (1988).
In 1935, J. Ridley Stroop introduced a color naming experiment known as the “Stroop Effect”. The findings of his experiment showed that it was much faster and automatic for his participants to read a word compared to when they were instructed to name the color of the word. Stroop proposed that the participants of his study were much slower at naming the ink of the list of words, indicating that people automatically process the meaning of the word before perceiving color. This interferes with the ability to process color in the incongruent condition, and consequently delay the

Stroop Effect Essay
1597 Words | 7 PagesThe Stroop effect was established by John Ridley Stroop in 1935 and has since become increasingly influential through its replication in published works. This effect illustrates the interference in human perception (Hilbert, Nakagawa, Bindl, & Buhner, 2014) and is a perfect example that describes situations in which task-irrelevant stimuli are hard to ignore. This study aims to investigate whether the fast and automatic processing of the colour denoted by a word will interfere with the ability to identify the font colour of the word. According to Raz, Moreno-Iniguez, Martin and Zhu (2007), Stroop effect is the difference in response time between congruent and incongruent stimuli – increase in time taken to name the font colour when it differs from the colour denoted by the word

Since the awareness of the object’s color is stored in the brain memory, an individual will automatic define the object is of a particular color. Hence, the assumption that the object color does not replace to other color. The earlier example of banana can used to relate.

For example, if a person was an alcoholic that label will stay with them forever and people will judge the person based on that label. In the recreation of the experiment Schulman discovered that white students were more likely to shock the black learners than the white learners. The percentage margin was of 70 percent to 48 percent. As the book says, “... They imposed more shocks on the Black learners that on the White learners.

Nonetheless, it could be argued that the semantic level of processing would be different for all individuals depending on their background and life experiences, as perhaps some words are understood more widely than others. It also depends on the language used to present the words and if the language was the first, second or possibly even the third language of the

They showed the tribe members and English speakers a sheet with a series of colours and asked them to recall the colours. The researchers reported that the Zuni people had significant difficulty recalling the colours yellow and orange. The reason for that was because the language Zuni only has one term for the colours yellow and orange.
Examples Of Chunking Theory
1752 Words | 8 PagesIn essence, chunking is established as one of the mechanisms for human cognition process. It is crucial in explaining the relationship between the external environment and the internal cognitive processes (Reed, 2010). Empirical evidence in support of the relevance of chunking theory exists, especially in relation to the way that humans perceive words, paragraphs and words as single units, overshadowing their representation as comprising of collections of phonemes or letters. For example, the chunking theory explains how skilled readers have a tendency to be insensitive to deleted or repeated words. Studies that use information concerning timing of responses to ascertain the presence of chunks exemplifies evidence on the relevance of the chunking theory are particularly useful in understanding effectiveness.

During the control period an illegal letter string was presented for 1 s, followed by a 1 s white fixation cross during which subjects were instructed to maintain central fixation. Eight illegal letter strings, balanced for length with those of the active blocks, were presented for each control
Stroop Experiment
220 Words | 1 PagesThe study of the link between automated operations and inhibition has been seen by psychology scholars as one of strong importance over time. John Ridley Stroop (1935) demonstrated that a automated operation like reading words interference the execution of not automated actions. In the experiment conducted by Stroop, participants read words denoting colors (eg. Red,Yellow and Green). Regardless of what color that was written; when participants had mentioned the colour which was the written word, they did more slowly when the word "red" was written in "green" and quickly when the word "green" was written in green, ignoring ink color reduces the speed of reading.
The Stroop's The Stroop Effect
148 Words | 1 PagesNamed after John Ridley Stroop, the Stroop Effect demonstrates that people read words more quickly and automatically than they can name colors (De Young). A very common way to test this is to have multiple subjects read a series of colors that are written in a different color ink. For example, if the word is blue, but is written in a green ink, green would be said allowed. If this is the case, then will the subject read the word with the same color ink faster than the words with different colored ink?

2021 Words | 9 PagesProcessing speed has been proposed to be a key cognitive resource (Kail & Salthouse, 1994). It is thought that interference occurs in the Stroop test because words are read faster than colours are named. R Schweickert showed that the order of processing is task dependent. In a task that requires the participant to name the colour of the word, much like the Stroop Task, the word is first processed and then the colour. (Schweickert, 1978).
Stroop Effect Experiment
2721 Words | 11 PagesAccording to Morton and Chambers’ (1973) assumption on speed of processing models, it is assumed that we are able to read words faster than naming colours. It appears that our mind chooses to receive specific presented stimulus before others. Due to this, when the word itself is a colour and the ink another colour it is harder to focus on only saying the colour of the ink, as the automatic process of reading takes over, and the two dimensions clash. However, this is not the case when the words are congruent. Thus, this assumption provides a strong possible explanation for the obtained
