Stroroop Task Lab Report

The purpose of this experiment was to determine if cats have a color preference. I wanted to do this experiment because I took an interest in my cat’s vision. My hypothesis was that my cat would prefer the color blue. I used 5 different colored balls of yarn. They were placed in the same spots and sequence each time. I conducted this experiment for a total of four-weeks. I set my cat up behind a line of painter’s tape and let her approach a yarn ball and play with it. I recorded how many times she approached each color. At the end of the experiment I discovered that my hypothesis was not supported. My cat chose to play with the yarn colored black rather than

The purpose of this experiment is to determine which stimuli sowbugs prefer more, moist or dark. However, to confirm that sowbugs prefer dark and moist environments we had to create an experiment to prove this. We proved sowbugs prefer dark environments by using a lamp to create a light environment and cardboard over half the petri dish to create the dark environment; the sowbugs chose the dark side. Then we proved sowbugs preferred moist environments over dry ones by creating a wet environment on one side and a dry environment on the other side of the petri dish. After our final experiment, we were able to determine that sowbugs prefer the dark stimuli over moist stimuli.

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

The independent variable was represented by three conditions; three word lists printed in a variety of color inks. Two of the lists consisted of word colors; one in black ink and the other in incongruent colors. The third list consisted of square blocks in contrasting colors. The dependent variable was the time taken to name the black ink words, the square block colors, and the color names in

The hypothesis is that when trying to remember the word pair list with whatever memory methods used, the beginning and ending word pairs will be remembered most often. The subjects that were chosen came from Indian temple friends and classmates in chemistry class. The target population was eight subjects in three groups, which was a total of twenty-four subjects. There were eight subjects in the control group and eight other subjects each in the two experimental groups. They were divided into control and experimental groups randomly being a mix of temple friends and classmates. A independent variable is manipulated or changed. The independent variable was the word pair list needed to be memorized. The dependent variable is what is being measured in an experiment, which was the results of the word pair test. It was a single blind experiment, which is when only the participant does not know whether they are part of the treatment or control group.

Abstract: This experiment was exploring our curiosity of sowbugs and their preferences. Our main question was about how the sowbugs natural diet can affect their preference for sodium chloride also known as table salt and glucose which is also known as sugar. The experiment involved testing how much time each sowbug spent in each substance when in a tray with both salt and sugar on opposite sides.

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

Wittenbrink, Judd, and Park (1997) studied eighty-eight people from the University of Colorado, who were in a psychology course, in order to receive points for their class. African Americans were not included. Caucasian American participants had to do three irrelevant assignments. One involved classifying to which race people belonged to according to first names. In this way, a connection with race categories was reinforced and was used as group primes. Following this, they had them do a response time assignment (out of awareness procedure), where they were asked if different strings of letters on the computer were a word or were not a word this was part of the Lexical Decision Task (LDT) (Wittenbrink, Judd, and Park, 1997). Before presenting the words

The Stroop test consisted two major posters of word lists: Incongruent list and Neutral list. Each poster included 20 words in 2 columns of 10 words each. All letters were stenciled, capitalized and 1 ¾ inches high. Both incongruent and neutral words were listed on the 56 x 71 cm posters Stopwatch with 0.01-second accuracy was used to time to measure how long participants took to read both incongruent and neutral word lists, which is a dependent variable for this experiment.

In addition, classic experiments often carry out in an artificial laboratory environment in which causing low validity and confound the‬. The tight control over the experiment may lead not be able to generalize the results into real life situation or replicable. In this case, such studies may mislead people and it is not worth to be focused. In the study of Asch (1951), a group of eight individuals (7 confederates and 1 naïve participant) sat in a room and they were asked which of three unequal vertical lines matched the given one. The study has low validity ecological validity as it was carried out under controlled

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.

In Stroop’s (1935) interference article, it was discovered that there is more interference in color naming then color reading. The experiment described in the article tested whether there was more interference from words or from colors (Stroop 1935). Two tests were administered each with a separate control. The RCNd test determined how fast one could read color names where the color was different from the color name while the NCWd test determined how fast one could name colors where the color was different from the word on the page. The mean time for 100 responses increased from 63.3 seconds on the RCNd test to 110.3 seconds on the NCWd test or an

The experiment consisted of a line judgement test, a naïve participant, and several confederates who had determined what their answers would be beforehand. To have a valid result of conformity, the naïve participant was made to believe that the confederates were real people just like them. Lines consisting of A, B, and C were presented to both the confederates and the naïve participant. Once presented with the three lines, they had to verbally state out loud which of the three lines were the same length in comparison to the target line. The experiment was purposely designed so that the naïve participant sat at the end of the table, thus allowing him to be the last one to give an answer. The results showed that out of the eighteen trials that were conducted, twelve of them consisted of the confederates purposely lying about which line they thought was the same length as the standard line (Asch,

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.

He had the experimenter come in dressed in a lab coat and explained that they were to ask a series of word associations to the learner and administer shocks for incorrect answers. As the number of incorrect answers increased so did the intensity of the shocks given. Voltage of the shocks ranged from 15/ slight shock to 300/danger to 450/xxx. The shocks were a form of punishment. The naïve subject was unaware that the shocks dispensed were simulated.
