simple reacton time

INTRODUCTION Simple Reaction Time (SRT) is a test which measures simple reaction time through delivery of a known stimulus to a known location to elicit a known response. The only uncertainty is with regard to when the stimulus will occur, by having a variable interval between the trial response and the onset of the stimulus for the next trial. Like Choice Reaction Time (CRT) it is useful for testing general alertness and motor speed, and is often sensitive. Researchers long ago discovered that complicated decisions lead to slower reaction times.

By carefully manipulating tasks, we can dentify the different through processes involved in reaching decisions and thereby determine approximately how long each mental step takes. OBJECTIVES To acquaint students in reading laboratory primers and organize data into summaries and graphs. APPARATUS Stopwatch PROCEDURE Part I Select your laboratory partner and toss a coin to determine who will be experimenter (E) and subject (S). S holds the timer. At E’s go signal, S starts the timer and must talk of free association while making an estimate of 12 second interval. E records the estimate in Table l.

S should not see the face of the timer or the data being recorded. Perform 45 trials. Then, E and S change roles. Make 10 trials for each subject. Part II Repeat the above procedure but this time with the timer facing S and no free association is required. Perform 45 trials. Then E and S change roles. Make 10 trials for the second subject.

The subject was given 45 trials of free association. In the second column is the Last Word Spoken. Obviously, in this, lists the last word told the subject to experimenter in every trial of 12-second interval. And the last column is the Reaction Time (in seconds). This column shows the estimation of the subject of 12 seconds of free talk per trial without looking at the face of the timer. In the second part, the first column also of the tables 1. is the number of trials which is 45. In the second column is the estimation only of every subject to 12 seconds, now while Constructing properly the tables and fgures in scientific report is very important because with these, the data will be understood easily. The significant findings in part I and part II is that it is more likely for the subject to obtained greater than or less than 12 seconds to his/her reaction time. The subject might be distracted due to the environmental factors which caused delayed reaction time. The independent variables in the experiment are age, gender and culture.

While the dependent variables, are the reaction time or the esponse of the subject to stimulus and emotions. CONCLUSION It is important in a scientific report to have a properly constructed graphs and to organized data so that the data will be systematic and easy to understand.
