Sleep Deprivation Report
Abstract
390 West Point cadets that are all enrolled in PL 100 took part in an experiment designed to test both their simple reaction times as well as their choice reaction times; each participant was subject to both the experimental and control groups. What the experiment consisted of was a simple task in which the participant had to press any key as fast as possible upon being presented with a single stimulus. The other task consisted of two different stimuli appearing, in no particular order or pattern, on a computer screen and the participant had to choose between two keys to click according to the color of each stimuli. After receiving all the data, it was obvious that the simple reaction times were quicker than the choice reaction time.

Our experiment had a lot of room for error. One of the factors that may have affected the results we received could be the level of fatigue each cadet was at. Sleep deprivation may have slowed the reaction time of some participants, it is true that reaction time gets slower when the subject is fatigued (Welford 1968, 1980). If the participants completed the tasks in a room full of noisy people or other distractions, this too may have contributed to slower reaction times; Trimmel and Poelzl (2006) discovered that background noises stretched reaction time by slowing down parts of the cerebral cortex. Under the conditions, this experiment proved that simple reaction times are in fact faster than choice reaction times. This makes sense because the brain only has to worry about a single stimulus. Next time we can test a variety of stimulus, such as shapes or words under a more controlled environment (i.e. a quiet room), this way we can get a more accurate, better understanding of reaction

    The purpose of this experiment is to determine the response time for dominant and non-dominant hand for visual stimuli, and using only dominant hand to test auditory and tactile response. Also, to test involuntary the response time for the reflex of the knee from calculating the distance. Based on my group hypothesis, we said that visual stimulus dominant hand had a faster response time than non-dominant hand because the dominant hand is use more often thus repetition creates stronger connection. For only dominant we said that auditory response has the fastest reaction time because the auditory stimuli gets process faster compare to tactile and visual that has to travel longer to reach frontal lobe for response decision. For involuntary response,…

    The aim of this study was to assess whether Stroop interference did indeed replicate with modern day students. Undergraduate students sample was obtained consisting of 12 females and 6 males, who are students in experimental psychology class. The independent variable was the condition of the stimuli with 3 levels (low, medium and high interference conditions). The dependable variable was the reaction time for the correct responses to the low, medium and high stimuli and the number of errors per condition. A one-way repeated ANOVA resulted in that there was a difference in reaction times and number of errors as the level of interference increased. ATukey’s HSD test found that there was a significant difference between the low and high interference levels and between the medium and high interference levels, as well. Also, there was no significant difference between the low and medium interference levels. That’s why the students didn’t replicate Stroop’s findings. There was a possibility that the sources of interference, like gender effect, auditory and visual distracters influenced the data.…

    2. The objectives of the first part of this lab is to observe and measure the reaction time to visual cues and compare this to the reaction time to auditory cues, to determine which stimulus would cause a longer reaction time, and to compare subjects’ reaction times by analyzing the data collected. For the second part of the lab, we will observe which muscle groups are involved in plantar flexion and in dorsiflexion of the ankle, if different stimulus strengths change the reflex time, and to determine conduction time from tendon tap to response of the gastrocnemius muscle in the Achilles reflex arc and of the quadriceps muscle in the patellar tendon reflex arc by recording the results using the Labscribe software and analyzing the data.…

    Therefore for Subjects 2, 4, and 6 the body is faster than average of taking impulses from the occipital lobe to the motor cortex of the brain which then produced the movement. This and different life experiences lead to the 3 subjects to be faster than the other 3 subjects. https://www.scienceworld.ca/resources/activities/reaction-time-ruler The second reaction time test is the sorting of cards in two different ways. One trial involved sorting the cards by color and the other by sorting the cards by suit the fastest.…

    The Stroop Effect

    For example the reaction time will differ from the different stroop effect experiments.“The first test is easy because the color and meaning of the word are congruent. There is no conflict.The second test is hard because the color and meaning of the word are incongruent. This creates a conflict that the brain has to resolve.” ( Para.1) . How come there are different reaction times in the test? “In two classic experiments, Stroop first compared reading a list of words printed in black with reading the same list of words printed in incongruent colors. Stroop found that there was little difference in reading time for the two lists. Stroop then compared the naming of colors for a list of solid color squares with the naming of colors for a list of words printed in incongruent colors. Subjects averaged 74% longer to name ink colors of incongruent words.” https://www.rit.edu/cla/gssp400/sbackground.html . For instance it averages 74% longer to name the ink colors of incongruent words in this experiment. “In two classic experiments, Stroop first compared reading a list of words printed in black with reading the same list of words printed…

    The experiment tries to show that people can not only create images but also mentally transform them. They present the subjects with two 3D line-drawing of random block shapes. The subjects are asked to decide if the two images are the same object by pressing two different keys on the keyboard. In some cases the two images are the same object with one rotated by some degree. In other cases the two images are mirror images that are similar but not identical. The mirror images are also rotated sometimes. The dependent variable is the reaction time. The independent variables are stimuli that have the same shapes vs. stimuli that have different shapes, and the degree of rotation. The control conditions are the multiple trials and the selection of only correct responses. The hypothesis is that if the reaction time is affected by the degree of rotation of the images, subjects perform the task by mental rotation of the drawings because it takes time to rotate the mental images just like real images. The result shows that the reaction time is indeed affected by the degree of rotation; therefore, it demonstrates the hypothesis that people can mentally rotate images. It takes more time for subjects to react when the degrees of rotation increase. There are some methodology problems in this experiment design. First, the block-shape 3D images are hard to identify even one at a time for some people and the test only takes correct answer into consideration. The repetition of the tests may cause fatigue to some subjects and the correct answers can be generated by random clicking of images. Second, the block-shape objects are not something that we can encounter in the real life so the subjects may have to take extra effort to analyze the images. Finally, the correct answer can be derived by ways other than mental rotation. For example, you can simply just find a starting point of the block-shape images and ‘walk through’ the images to see if the two images have the same ‘route’…

    On arrival, participants and the two observers entered the room and had the participant sit down in front of a desk. Participants received instructions orally and were asked if they had any questions before we continued with the experiment. The instructions listed each participant to name the shape of each item and avoid reading the word within the shape. Participants were asked to begin at the top left corner of the page and move left-to-right, row by row. In congruent shape trials, each shape matched the word within the shape. In incongruent shape trials, the shapes did not match the word within the shape. They were asked to repeat this task six times. Additionally, to control order effects, we counterbalanced the experiment by alternating trials for each condition. The condition that was tested first was the congruent trial, followed by the incongruent trial and it kept alternating in this manner. It was asked that participants should not hold the paper but were allowed to point at the paper on the table with their fingers. If participants felt stuck, they were instructed they may “skip” and move to the next shape. When the participant finished each task, the observer was to record the seconds it took for participant to finish naming the shapes. For each of the fifty-eight participants, their three congruent and three incongruent scores were to be averaged…

    In this experiment two pictures were represented in modification for each trial. On half of the trials the two pictures were alike but in the other half the pictures changed in some way. For each pair either the pictures appeared instantly after each other or they flickered. The participants in this study consist of a psychology class in the College of Staten Island. In order to start this experiment, students were asked to sign in to their CogLab accounts. To start the first trial of the change detection experiment, participants were required to press the space bar. One picture will appear after the other. The task in this experiment is to detect whether or not there is a change in the two pictures. If the image changes students press the “c” key but if the image doesn’t change students press the “n” key. This test measures our reaction time as well as our ability to detect changes in the pictures. The independent variable in this experiment is was the flicker and no flicker conditions. Two dependent variables were measured which were reaction time and proportion of correct judgments. Reaction time was the time between the appearance of the stimuli and the time that it…
