For me, who loved cello since childhood, the piano is my good friend on the road of music learning, because it plays a positive role in promoting my learning to play the violin. Did you know that there is a term for this, namely "positive migration", also known as "enabling migration"? Scientifically, it means that one kind of learning plays a positive role in promoting another kind of learning. Specifically, the study of piano makes me more familiar with the knowledge of music theory, and improves my reading ability of staff, so that I have a deeper understanding and cognition of cello. This makes me love the cello more, and I feel more comfortable training and playing the cello. This feeling is really great! This is just like a person who knows English can easily master French, learning mathematics is conducive to learning physics, learning sketch will have a positive influence on the future study of oil painting, and so on. These are the effects of positive transfer.

My love for jogging probably started when I was an embryo, because I love jogging so much. It's like my friends, my family, my brothers and sisters, they always influence me and accompany me. I've been practicing it since I was a kid, learning how to run faster, longer, and keep pushing my boundaries. Here it is: Fitts and Posner three-stage model. This theory was proposed by Fitts and posner in 1967.

The first stage is the cognitive stage, the beginner stage, in which I go to a running class almost every week at least once, during which I need a lot of mental activity to understand movement patterns and properly coordinate my limbs. After class, I will often go to practice, regular self training. When I got a certain score, I reached the second stage, the association stage, that is, the medium level. At this stage, I have learned to run, learned the correct running knowledge, learned the essentials of running. At this point, my goal had shifted from learning how to solve movement problems to improving movement. I found a one-on-one coach so I could get more professional guidance, and instead of training myself outside of class three times a week, I started training myself five times a week. After I won the first place in the school long-distance race, I entered the third stage, the autonomous stage, that is, the master level. At this stage, I started to focus more on strategy and game skills. I started coaching one-on-one twice a week and went to more games. This not only improved my sports skills but also increased my competition experience. This is really great!

This is Mio, my classmate's one-year-old Muppet cat. He loves cat scratching sticks! I use it and its favorite snack as a demonstration of the psychological refractory period of the dual stimulation paradigm. I don't know how to make the video, but you can imagine that it's still processing the first stimulus (the feather on the scratching stick is about to touch it) and the second stimulus (a person is trying to tempt it with a favorite snack). While this is somewhat difficult to imagine a "Psychological Refractory Period," it does support the single-channel hypothesis used to explain PRP. When the second stimulus was given, Mio was still processing the first stimulus, so he could not immediately respond to the second snack. PRP would be the difference between Mio's response time to the treatment alone and his response time to the treatment after being stimulated by the attraction of the feathers on the cat's scratching stick.

Cold science, therefore, is the time it takes for a sensory organ to respond to a certain stimulus. It refers to a period of time during the reaction, not the whole reaction time. For example, if a certain receptor F makes a predictive response to the 1-second reserve period and forms a habit, then giving a stimulus signal at another time other than 1 second will no longer respond, or make the response error larger. Thus, this is a result of the psychological refractory period phenomenon in action.

Do you have a habit of drinking water before meals? Yes, I do. If I don't drink a little water before I eat, I will subconsciously pick up the glass and drink even if there is no glass of water in front of me. Only when I'm sure there isn't a drop of water in the glass will I start to think about where there is. This move is based on my procedural memory. Since I was a child, I was told by my mother that drinking a little water before eating can make the other side of the stomach put down food less, which will help you lose weight. Therefore, I gradually developed this habit, so that it has become my habit. Scientifically, procedural memory is usually less easily altered, but it can be performed unconsciously, either as a reflex action or as a combination of more complex actions (declarative memory, by contrast, is generally easier to express verbally). Examples of procedural memory include learning to ride a bicycle, type, play a musical instrument, or swim. Once internalized, program memory can be very durable. Therefore, I feel that the habit of drinking water before eating may be difficult to break for a lifetime. (After years of experiments, drinking water before meals doesn't make me thinner)
