The purpose of our experiment, called The Stroop Effect, is an outcome of our attentionalvitality and flexibility. Most humans can read words more quickly and automatically than they can name colors. Therefore, if a word is shown in a different color ink than the color actually spells; for example, if the word blue is actually written in reen ink, we will have a harder time separatin the word from the color. !e are testin to prove that youner children "approximatelyaes # to $%& will be able to complete the Stroop Test faster than older adults "approximately aes $' to %(&. The procedure is rather simple; we athered a wide rane of test sub)ects varyin by their aes and showed them the Stroop *hart. Then we told them the directions in
Compress the safety bulb, hold it firmly against the end of the pipette. Then release the bulb and allow it to draw the liquid into the pipette.
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
The purpose of Scientific Method Lab is to determine which variable mass or height will have the greatest impact on the speed of a sphere. The generalized purpose of this lab is to practice scientific method and to learn how to write lab procedures.
The purpose of the Stomatal Density Experiment was to examine the differences in the number of stomata found between young and old leaves in a single plant. Stomata on small surfaces, are small pores in the epidermis that allow carbon dioxide to enter aiding the process of photosynthesis, and when the process is done it will release both oxygen and water vapor. Stomata can control the amount of gas exchange but openly and closing the pores. Also, the stomata is usually found on the bottom part of the leaf. How the age of a leaf can make a difference in the number of stomata on it.
Sentence Structure subtest of CELF-Preschool 2 presents a series of verbal sentences and the student needs to point to the correct picture. On this subtest, Tara Noel’s performance was below average range with a standard score of 9. Tara Noel performed as well or better than 37 percent of all students when compared to the norms for her age. Tara Noel was able to point to 10 of the 22 pictures correctly. The correct pictures do show how her vocabulary affected her ability to answer. She knew
The procedure is simple. On the computer screen, twelve words are revealed one word at a time in the form of a list. After the last word, a matrix of twelve words is shown. The matrix is a table of twelve words, some of which were on the list, some of which were not. Participants in the task chose which words they believe were on the list, using free recall to select words in any order. A new list begins when participants believe they have all of the correct words from the matrix. The cycle begins again. A list of twelve words are presented, a matrix appears after the twelfth word, and participants select words according to their memory of what was on the list. There are six lists in total, with no practice trials, however there are breaks in between to express the differences in each list.
Whilst participants showed an average of 0.62 on the APM-SF, 0.76 on the CAB-I and 0.63 on the MRT. It was hypothesised that the lower participants scored on the TSP and the higher they would score on the other three tasks. With a negative correlation determining the impact of perceptual and cognitive processing on the TSP.

There was a pause with a blank screen, then the subjects were shown two different colors that were half and half on the page, like yellow or blue. The subjects then had to indicate which color word initially was presented to them. “He did not investigate the influence of this paradigm on normal Stroop interference, however, and his task differs from traditional tasks in having a delayed, binary response” (swarthmore.edu).
The results showed that the older age groups could distinguish more colors in less levels of lighting than the younger age groups. The younger age groups would be considered 7 and under, while the other age groups would be considered the older age groups. The results of the experiment refuted the original hypothesis, which is: If age affects the amount of light needed to help distinguish colors, then younger ages will be able to distinguish colors in less lighting compared to older ages.
He then observed that this method would be inaccurate in measuring the capacity of iconic memory. He proves that humans tend to read from to top to bottom and within this experiment this took too long and may have caused the bottom letters to fade by the time that person read the letters at the top. So because this became so problematic, he created a technique called partial report method. This technique used the grid of letters, but also used a high, medium, and low tones. Basically, whichever tone was used, the individual read from the top, middle, or lowest line. Other experiments formulated from this particular experiment shows the estimated duration of iconic memory. It shows that after a quarter of a second in visual memory, old information is replaced by new
The Wisconsin Card Sorting Test (WCST) is often known as an ideal neuropsychological test of set-shifting ability. During the WCST a number of incentive cards are shown to the participant or patient, the participant is told to sort the cards in the correct order; without being told the correct order the participant is just told whether or not the order is right or wrong. Before they started using the computer based test the WCST used paper cards and was carried out with the experimenter on one side of the desk facing the participant on the other. The test takes approximately 10 - 20 minutes to carry out and generates a number of psychometric scores, including numbers, percentages, and percentiles of: categories achieved, trials, errors, and
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.
