  • The Stroop Effect And Reaction Time

    performing a naming task which impacts reaction times. In the Stroop (1992) study found that color naming had a slower reaction time when the color words were printed in a different color, but even slower reaction time occurred when the color and word were completely separate from one another. The current experiment used Stroop task to determine the impacts of reaction times to test the hypothesis to see if there is a significant difference between the reaction times amongst the four levels of the Stroop task. Specifically seeing if the naming of color words printed in the same color had faster reaction times than naming the color of word printed in different…

  • Caffeine And Reaction Time

    Do you start your day with a fresh, steaming cup of coffee? Do you drink coffee to satisfy your addictive craze? Do you need caffeine to keep you awake? Caffeine is the most widely used drug in the world, consumed by some 80 percent of American adults every day. Caffeine generally improves alertness and reaction time, but evidence is inconclusive for its effect on higher memory and reasoning processes. Smith (2012) compared those who received caffeinated coffee had significantly faster simple…

  • Reaction Time And Regression Analysis

    Results indicated that average reaction times for the auditory and visual stimuli tests were both significantly different from that of the control conditions (see table 1 and figures 1, 2 and 3). Differences in average reaction time differing from the control test (test 1) range from as little as 4 milliseconds (test 2, test subject 2) to that of 67 milliseconds (test 4, test subject 3) (see table 1 and figure 1, 2 and 1.3). According to the averages of the percent increase in reaction time, the…

  • Reaction Time Lab Report

    Measurement of Reaction Time According to the Merriam-Webster Dictionary, reaction time is the time elapsing between the beginning of the application of a stimulus and the beginning of an organism's reaction to it. In the lab that was conducted, the reaction time of the muscular and nervous system was tested. In the muscular system, specific thenar muscles such as the adductor pollicis brevis, abductor pollicis, opponens pollicis, and the interosseous were involved and tested to cause…

  • How Does Caffeine Affect Reaction Time

    What effect does caffeine have on the reaction time of an individual? A psychology class will be doing an experiment to see if caffeine affects a participant’s reaction time. The results will show if the drug (caffeine) has any effects on an individual. The hypothesis is that participants who had Caffeinated Cola will have a larger positive decrease in reaction time than the participants who drunk decaffeinated Cola and water. Results Table: The effect of a caffeinated drink and a decaffeinated…

    Experiment 4: Reaction, Movement& Response Time in Decision-Making Tasks I. Question 3: (i) Why are multiple repeated trials in each task required (ii) Why do we need to complete checks on the data (identify errors etc)? (iii) Why was there a variable fore-period between the start of a trial and the appearance of a stimulus in the tasks? (iv) Why was randomization necessary from Task 1b onwards? (v) Why was 80%(congruent) vs 20%(incongruent) split used in Task 2? II. Background (i) The…

  • Dropper Experiment Lab Report

    Ping-Pong ball from the same height and record the time for each dropping. Then, using the equation “h=1/2g*t^2 to calculate ‘g’. For precise, we still need to find ∆g, therefore, the final data about g=gave+∆g. Method: Before we start to do the experiment, we need to find a position which can except the wind and flat ground. After that, two people as a group, one is a golfer, and another is a dropper. First, they measured use tape measure to measuring the distance between dropping place and…
