Independent Variable Fo 8a

In experiment 1, participants were instructed to press a key to determine if the stimulus was red, blue, yellow, or green. On the second half of the experiment, the stimulus appeared in grey with only one colored letter which was positioned randomly. Error rates for the experiment were below 2.5% for each condition, which is quite low. Experiment 2 was the same as experiment 1 except that there were 114 data collections instead of 288 and there were 36 practice trials instead of 72. According to experiment 1 and 2 it is suggested that the effect of

If the response time for this experiment by saying the word” now” falls between 100 and 200 milliseconds, I would conclude that

The Stroop (1935) effect is the inability to ignore a color word when the task is to report the ink color of that word (i.e., to say "green" to the word RED in green ink). The present study investigated whether object-based processing contributes to the Stroop effect. According to this view, observers are unable to ignore irrelevant features of an attended object (Kahneman & Henik, 1981). In three experiments, participants had to name the color of one of two superimposed rectangles and to ignore words that appeared in the relevant object, in the irrelevant object, or in the background. The words were congruent,

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

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.

This may also have a similar effect in other movement tasks such as complex hand motions. Would temporal decision-making be affected more, less or the same way with this type of motion instead of crossed/uncrossed arm movements? In my opinion, I think it could potentially mean more of an effect on decision-making because of the complexity of the movement. It is evident that because we are not used to such movements in everyday life, it requires more of an effort and concentration thus allowing for more mistakes to occur in the execution, when predicting limb movements. Similarly, my prediction in this regard, is that since we are not constantly engaging in complex hand motions, it will essentially become more difficult and planning to do such a task will have increased error, which will probably lead to a significant effect on judgments of temporal

Powell (1986) conducted a study in which individuals viewed a photo or slide. Individuals were required to scan images and decide on an image for the entire display (Powell, 1986). Objects were pointed to, and subjects were asked to identify its location (Powell, 1986). The subject was asked to close his or her eyes and were shown another image. The subjects were to decide if the object was in the correct position (Powell, 1986). The subjects would hear one of the objects and was required to focus on the object while keeping the entire image in his or her mind (Powell, 1986). When the next object was identified, the subjects were to move from the first object to the second watching a black dot moving in a straight line (Powell, 1986).

The aim of this study was to further investigate whether the interpretation of an ambiguous stimulus is influenced by immediate past experience, and, therefore, by the establishment of a perceptual set. It is based on an experiment conducted by Bugelski and Alampay (1961).

Patients tend to correctly identify shape, color, and motion of inputs. In a forced choice experiment, where the subject is asked to identify certain features of a visual cue, the subject will perform much better than chance even though they feel as if they are randomly guessing (2).

For instance, the trials were conducted in English. The potential confounding variables such as foreign language speakers, learning difficulties, or physiological anomalies, cannot be discounted. With regard to the Stroop effect, various other factors can be tested in order to see what influences reaction time and what doesn’t. For example, instead of investigating different age groups, one could compare nationalities. The most valuable results would come from testing two nationalities, one native English speaking and the other foreign

We replicated the first and second activity I just explained above. We called the colour words written in the same colour, congruent and the colour words in different font colour, incongruent. The aim of this experiment was to determine whether there were a cognitive skill difference when the participant were given either the congruent or the incongruent task. If they got the congruent or the incongruent list were random. We investigated the difference in time for naming colours and reading colour names and compare the interfering effect of colour stimuli upon reading names of colours with the interfering effect of world stimuli upon naming the colours

The reaction time (RT) of students was measured in the experiment to determine whether light or sound stimulus initiates a quicker response time. The question of whether or not RT was related to movement time (MT) was also challenged. Each student performed two test in random order; one testing the reaction time of a red light stimulus, or visual reaction time (VRT); and the other testing the reaction time of a “beeping” sound stimulus, or auditory reaction time (ART). The student completed the VRT trial by simply receiving the stimulus and pressing a button. The student placing and holding their hand on a button starts the ART trial. Once the student receives the stimulus (beep) they press the adjacent button as fast as they can. The ART trial does not only include the data of the RT, but also the data from the MT. Having previous knowledge that light travels faster than sound; one can predict that VRT is faster than ART. The prediction that MT is independent upon RT can be made with the thought that there are so many opposing variables that could affect the MT of an individual unrelated RT such as old age

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.
