Three. foreword

Cross test is a common test to compare the differences between different individuals in the speed and accuracy of completing work. From the end of 19, we used erasure test to understand and compare the perception speed, recognition accuracy, attention, mental retardation, fatigue, proofreading efficiency, etc. In order to complete the erasing task, the subjects need to pay great attention to identify the specified specific object accurately and quickly among many similar objects, which can reflect the persistence, willpower and fatigue of the subjects to some extent.

Fourth, the method

(4) Procedures

1, the experimental material is a randomly distributed numerical table, including 25? 25 numbers. Set 3 as the elimination target in advance. The subjects were asked to check the number table line by line and draw the target number by clicking. When the subjects think that the erasure is completed, the experiment ends;

2. This experiment is divided into quiet environment and interference environment. The subjects completed the erasing task in two environments.

Verb (short for verb) result

1. According to the data in table 1, there is little difference between the crossed-out number c, the omitted number o and the crossed-out number w;

2. From the perspective of work efficiency E, subject 1 has the highest work efficiency E, and subject 3 has the lowest work efficiency E; 3. as far as accuracy a is concerned, subject 3 has the highest accuracy a, but it takes the most time t, and subject 2 has the lowest accuracy a, but it takes a relatively large time t. ..

Discussion on intransitive verbs

1, the experimental data is greatly influenced by the surrounding environment, especially the data that needs to be carried out under quiet conditions. 2, the number of experiments is small, the number of subjects is small, and the experimental data is unconvincing.

3. During the experiment, during the second experiment, the subjects were more relaxed, and the operation was more skilled, resulting in the practice effect, which led to the deviation of the experimental results.

4. The experiment needs to measure the stability of attention in daily life, but in this experiment, the subject will be more focused than in life, so the erasing efficiency of the subject is not necessarily consistent with his usual general work efficiency. 5. The overall work efficiency is about 0.693.

Seven. conclusion

1, the work efficiency of the first department is slightly different from the whole, slightly higher than the overall average, and the second and third departments are slightly lower than the overall average; 2. The overall work efficiency is not high;

3. There is a slight difference between men and women in work efficiency, and the attention stability of men is lower than that of women.

Psychological Experiment Report Model Part II: The Influence of Information Feedback on the Accuracy of Drawing Lines

Abstract: Taking 40 sophomores as subjects, this paper investigates the influence of information feedback on the accuracy of line drawing. The results show that (1) practice can improve the accuracy of drawing lines; (2) The accuracy of line drawing in the non-feedback group did not improve significantly, while the accuracy of line drawing in the feedback group improved significantly.

Keywords: feedback practice line drawing accuracy

First of all, the questions raised

Feedback, also known as feedback, is the basic concept of cybernetics, which refers to the process that the output of the system returns to the input and changes the input in some way, thus affecting the function of the system, that is, the process of returning the output to the input through appropriate detection devices and comparing it with the input.

For a long time, psychologists have applied information feedback to animal research. Pavlov discovered the law of functional activities of many advanced parts of the nervous system through the experimental study of reflex activities of animals and people, and founded higher nervous activity's theory. Feedback is one of the basic concepts of Pavlov's reflection theory. It refers to the process that the result of reflex activity returns to the nerve center, so that the nerve center can get the information of effector activity in time, thus adjusting effector activity more effectively. Nowadays, the method of information feedback is more and more used in teaching practice. For example, feedback students' scores in time after the exam, so that students can realize their own shortcomings and improve in time.

This study hopes to reveal the influence of information feedback on the accuracy of occlusion drawing through this experimental study. The research hypothesis of this experiment is: there is a significant difference in the accuracy of drawing lines before and after feedback, but there is no significant difference between pre-test and post-test without feedback; There is significant difference in posterior performance between feedback group and non-feedback group.

Second, research methods.

1, account

There are 40 undergraduates majoring in psychology in Modern College of Humanities and Sciences of Shanxi Normal University, whose vision or corrected vision is normal, and they have never participated in similar experiments before. 40 subjects were randomly divided into two groups (feedback group and no feedback group), with 20 subjects in each group.

2. Experimental materials

1) one piece 10cm? 10cm white card with a 2cm long straight line drawn on it. Put the white card with straight line into the frame parallel to the horizontal plane and located in the middle of the frame as the standard stimulus of the experiment.

2) Measure the size of the straight line drawn by the subjects with a mirror frame and a short ruler (minimum unit is millimeters).

3) Two pens for drawing lines and recording experimental results.

4) Each participant has three cards, numbered A 1, A2 and A3, which are used as the results of drawing lines before (pre-test) and after (post-test) practice respectively.

30cm long paper tape is convenient for fixing the distance between the subject and the white card. 1, experimental design This experiment adopts single factor and double factor (? Have feedback? With what? No feedback? ) experimental design. The experiment was carried out in pairs. There are 20 groups. One person is the subject and the other is the main test. After the feedback group experiment, the two exchanged roles. Subjects were divided into groups, and the experimental treatment arrangements were as follows:

Table 1

Pre-test exercise, post-test feedback group (20 people), 20 times, 80 times, 20 times, no feedback group (20 people)

Draw 20 times

Draw 80 times

Draw 20 times

3. Experimental procedures

1) Let the subjects 1 (with feedback group) sit at the desk, put a picture frame with a white card 30cm away from the front of the subjects, and draw a 2cm straight line on the white card. Put a piece of white paper A 1 behind the mirror, and put the pen in the hand of the subject behind the picture frame to block the subject's line of sight and prevent him from seeing the hand drawing the line and the drawn line. Then say the following instructions to the subjects:

? Please hold the pen with your usual writing hand, look at the black parallel lines in the picture frame, and draw horizontal lines on the white paper with your pen. You are required to draw according to the length of the line you see, so that the line you draw is as long as the line segment in the frame. When drawing a line, you can't see the line you are drawing and the line you are drawing. Draw a total of 20 times, starting from the left. You can move the hand that draws the line left and right, but don't move your arms, head and change your sitting posture. ? After confirming that the subjects understand the above instructions, start the pre-test and prepare to practice the experiment after completion.

2) Try to change a piece of paper numbered A2 and tell the subjects in the feedback group the following instructions:

? Now, please draw a line in the same way Every time you draw a line, I will tell you how long it takes you to draw a line, and ask you to pay attention to your feeling when you draw a line, remember this feeling and compare it with the feedback. If this picture is long, you should draw it shorter next time. If the picture is short, you should make it longer next time. In short, you are required to draw a line segment as accurately as possible. This is a total of 80 times, I believe you will draw more and more accurately. ?

Every time the subject draws a line, the examiner measures it at the fastest speed and immediately tells the subject the result of drawing a line, such as? Dragon? Just reporting dragons? , for example? Short? Just report short? If it happens to be 2cm, report it? Equality? Until 80 line segments are drawn, the practice experiment is over.

If it is a non-feedback group, say the following instructions to the subjects:

? Now, please draw a line in the same way After you draw a line, you are required to pay attention to your feelings when drawing a line. Remember this feeling and try to draw a line segment with the same proportion as the standard line segment according to the consistent line drawing standard. If you think this picture is long, you should draw it shorter next time. If you think this picture is short, you should make it longer next time. In short, you are required to draw a line segment as accurately as possible. This is a total of 80 times, I believe you will draw more and more accurately. ?

3) The examiner changed a blank sheet of A3 paper and said the following instructions to the subjects in the feedback group: Now please draw 20 more line segments. I won't tell you the result this time. Please draw as accurately as possible. ?

If it is a non-feedback group, say the following instructions to the subjects: Now, please draw 20 more line segments, and try to draw a line segment with the same length as the standard line segment according to the consistent standard. ? 4) Subjects exchange roles with subjects, and use three blank sheets of A 1, A2 and A3 to carry out experiments according to the above methods and the instructions of the feedback-free group (the results of drawing lines every time during practice are not fed back to the subjects). Other experimental procedures are the same as the above experiments. 5) The examiner records the data during the experiment and sorts out the experimental results.

All the data are calculated and counted by spss 16.0 statistical analysis software. The statistical methods used in this study are descriptive statistics and t-test.

Figure 1 40 average error changes before and after the test.

Observing Figure 1, it is found that the average error of post-test is lower than that of pre-test. The reduced significance level can be tested by t-test.
