The Effect of Visual Field Position and Type of Stimuli on the 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).

An interesting challenge arises when a task such as color naming is identified as both controlled and automatic, by varying the other task involved. Color naming is identified as a controlled process when the other task is word reading, but as an automatic process when the other task is shape naming. Cohen, Dunbar and McClelland (1990) proposed an alternative explanation of the Stroop effect, which does not distinguish between automatic and controlled processing. Instead, they proposed that automaticity is a range, and that Stroop interference depends on the relative degree of learning the particular tasks, not on processing speed.

It was found that tasks involving colors cause more interference. These two studies were similar to the present experiment, as they both required participants to verbally name colors while inhibiting themselves from naming the typed color, as fast as possible.

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

Introductory Psychology students (N = 305) from a mid-western university participated in the study online for course credit. Sixty-eight percent of the participants identified as female, 32% of the participants identified as male, and one participant did not indicate their gender. The majority of the participants were Caucasian (73%), and the average age of the participants was 19.04 (SD = 1.10).

It was therefore hypothesised that the reaction times for global judgments would be faster than the reaction times of local judgments. It was also hypothesised that consistent stimuli would be faster than conflicting stimuli in the local tasks.

The materials used for this study included PsychMate Student Version 2.0 (St. James, Walter Schneider and Amy Eschman.) Psychology Software Tools, Inc. Along with the PsychMate software, a computer provided by Queens College was used in order to successfully complete the study.

Participants in this study were 119 undergraduate students from a Canadian university. Gender selection was 36 males and 83 women with ages ranging from 18 to 51 years. As an incentive, the Canadian university psychology department awarded the participants with course

The experiment used the same red and green stimuli in each trial instead of other opponent colors such as black and white or blue and yellow. The small sample size studied could have also lead to random variation in the results.

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)

This experiment investigated the Stroop effect comparing response times between naming colour ink printed in colour-associated words and colour neutral words. Previous research of two-process theories which support Stroop's studies [cited in Edgar:2007] found that automatic processes can interfere with controlled processes. To test this interference further, colour-associated words were employed. Results of this experiment show a statistically significant difference in condition response times, with naming the colour ink printed in colour-associated words taking longer than those in colour

The results of the information processing lab support the text in a number of ways. As the number of choices increased, the total response time also increased, verifying Hick’s Law. This then indicates that as the trials became more complex, information processing time was influenced. However, the subjects were able to bypass the complexity of the task when they were able to preview the color or

1. The authors decided to do a replication of a study performed by of Ramachandran & Hubbard (2001) and Hubbard (2005). From this study researchers looked at individuals who had synaesthetes and how they interpreted shapes, numbers and colors. Results from their study showed that individuals who had synaesthetes performed better by interpreting certain pictures by using more of the ‘pop-out’ effect rather than using the serial search effect. It also “assumed that color and shapes are processed independently, which does not hold true for people who have synathecia, giving that some amount of grapheme processing must be required for the color to be included”(Ramachandran & Hubbard 2001b, 2003b). Due to these findings researchers decided to “correct”

Differences have been found in terms of internal consistency of colour associations, specificity of the colour selection, and in terms of the automaticity of colour association. However, the two groups were remarkably similar in the way of mapping pitch-lightness. It is suggested that both groups may use the same cognitive mechanism to map between the auditory and visual domain. In addition, synaesthesia might be useful for learning (experiment 3). The results have two main implications for me study. First, it suggests that synaesthetes and non-synaesthetes share same cognitive mechanism; therefore, several associations that exist in synaesthetes might be found in non-synaesthetes, or at least, could be easily taught to non-synaesthetes. Second, most studies on the grapheme-to-color synaesthesia rather than the sound-to-color one. This study demonstrates the possibility of associating the colored letter with its sounds. This particular approach of associations might be more appropriate to help dyslexic children to remember the relationship between letters and

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.
