Sun Xiaomeng bit her lower lip tightly and looked at Richard fixedly. Pen, fun, pavilion www. biquge。 info

Despite her efforts to think and recall, she only dabbled in this knowledge out of interest, and much of the literature was in English, mixed with a lot of jargon in animal psychology, and it was very obscure to read, leaving a fragmented impression and not very profound.

In addition, the noise coming from downstairs also made her unable to concentrate, and several times she vaguely remembered something and was interrupted by the construction noise. She was eager to rush downstairs and tell them to stop and wait for her to figure it out before continuing.

The kitchen door was silently pushed open again, and Sun Xiaomeng and Richard also looked at the door. She thought that Zhang Zi'an was back, and she was even more anxious, if he gaged out of place, she couldn't remember it.

There was no one at the door, and her gaze shifted downward.

Xinghai squatted in the doorway very energetically, staring at Richard with silver-gray eyes.

"Aga?" asked Richard as if he wanted to tell him.

"Meow ~ hide and seek!" Xinghai only said these few words, then turned around and ran away quickly.

To Sun Xiaomeng's ears, Xinghai just meowed a few times cutely.

She felt more and more that today's Xinghai was very strange, and she actually took the initiative to approach her many times.

"Hide-and-seek?" repeated Richard.

As if a lightning bolt split the eternal chaos, Sun Xiaomeng suddenly remembered that it was hide and seek!

"Richard, are you here to play hide and seek?" she asked, turning her head to Richard.

"Gah?"

Richard didn't understand what she meant. It wanted to say that Uncle Ben wouldn't play this kind of child's game, if he wanted to play, go with the black and white kitten, Uncle Ben would not accompany him - but in the face of Sun Xiaomeng, it couldn't say these words.

Since Sun Xiaomeng already knew that it could understand her words, since it didn't refuse, it was up to it to acquiesce.

She looked left and right, as far as a single man is concerned, Zhang Zi'an's kitchen is not too messy, but she wants it to be more messy now.

"That's it. She saw several glass spice bottles on the shelves, each the size of a child's fist, containing chicken essence, sesame oil, vinegar, salt and sugar. The five spice bottles are matched and are exactly the same size, only the color of the caps is different, which are red, yellow, green, blue, and white.

I'm sorry, borrow it without authorization, and I'll apologize to you when you come back later, she said to Zhang Zian silently in her heart.

Sun Xiaomeng placed the five bottles in front of Richard one by one.

Richard thought it would be a piece of cake for himself to identify the color of the caps, and without waiting for her to ask, he replied, "Red, yellow, green, blue, white." ”

Sun Xiaomeng smiled, "No, I'm not asking you about the color of these bottle caps...... But you're absolutely right, remarkable. Okay, now pay attention to me, how many bottles are there?"

"Five. Richard replied quickly, the question was too pediatric.

She picked up a stainless steel soup pot and snapped it upside down on the red bottle, completely covering it up.

"How many are there now?"

Richard hesitated, unsure if the one that was blocked counted.

"Five. It replied.

"How many can you see?" she asked.

"Four. This time it replied immediately.

Hearing these two answers, Sun Xiaomeng's heart missed half a beat, and his palms sweated slightly.

This may seem like a simple experiment, but it is the criterion used by Piaget, the most prominent cognitive development theorist of the 20th century, to measure children's cognitive ability, using the inspiration and inspiration he received from playing hide and seek with his son with toys, and based on this he composed a complete and comprehensive theory, called the "object permanence experiment".

To put it simply, this experiment is to put an object there for the subject to see, then block or cover the object, and then observe the subject's reaction. If the subject knows that the object has not disappeared, but remains in place, but is simply invisible, this proves that the subject has understood the meaning of "existence".

The difference between scientists and ordinary people is that they have a discerning eye and can interpret experiments from novel angles, such as Galileo Galilei who made two iron balls hit the ground at the same time to prove the law of free fall, or Newton used a prism to break down sunlight into seven colors, laying the foundation for spectral analysis......

The fact that the eye can't see, but knows that it exists, means that Richard's cognitive abilities are at least equivalent to that of a 1-year-old child.

Sun Xiaomeng put away all contempt. She was not dealing with a pet bird, but with an intelligent being. The difference between Richard and other parrots is probably greater than the difference between Einstein and ordinary people.

She took a deep breath, tried to maintain a calm expression in order not to stress Richard, and said, "Okay, pay attention, I'm going to make it a little more difficult." ”

Sun Xiaomeng lifted the soup pot halfway, quietly hid the red bottle inside in the palm of his hand, buckled the soup pot again, and put the right hand holding the red bottle behind him.

"Where's the red bottle?" she asked Richard.

Richard didn't see her quietly take the red bottle away, and replied, "Under the pot." ”

Sun Xiaomeng opened the soup pot with his left hand, and the pot was empty.

"Wha?" exclaimed Richard, then reacted, "Your right hand." ”

Sun Xiaomeng took out his right hand from behind him, and his right hand was also empty.

Richard thought for a moment, "In my pocket." ”

Sun Xiaomeng nodded, took out the red bottle from the pocket of his white coat, and placed it side by side with the other four bottles.

"Congratulations, you guessed it. ”

"Quack!

Receiving her compliment, Richard was in a good mood. It seems to remember something, and it seems to have played similar games before, with a slightly different form but the same essence. It's just that it didn't like the game at the time, because it was difficult to play, and it often encountered failures and setbacks, so it was always in a bad mood. However, after becoming an elf, the game seems so simple that it scolds its past self several times as an "idiot" in its heart.

Sun Xiaomeng smiled unnaturally, she couldn't accurately describe what mood she was in at this time, Richard refreshed her understanding again, and it was able to prove through this experiment that its cognitive ability was at least at the level of a 2-year-old child, and the experiment process was extremely easy, and it passed at one time.

She believed that even if the next experiment was carried out, Richard would still be able to pass, so where was the upper limit of it? 3 years old, 4 years old, 5 years old, 10 years old, 12 years old?

It can speak, think, and perceive, but apart from the appearance of a bird, is there any essential difference between it and a human?

In her memory, there was only one parrot in the world that had passed the experiment, and the death of the gray parrot was considered a great loss to the scientific and educational community due to its untimely death, which stopped at the cognitive level of a 5-year-old child.

Now, in front of her stood a living intelligent parrot, perhaps even better than the dead one!

She felt very sad, why did all the good things happen to Zhang Zi'an?

The kitchen door was pushed open again - with the experience of the first two times, she thought that Xinghai had pushed it open again, and her eyes moved downward, wanting to say hello to Xinghai and let it stay and not run, but she only saw a pair of feet wearing casual shoes.

Zhang Zi'an looked at her, then at Richard, and felt that there was something wrong with the atmosphere in the kitchen.

"What are you doing?" he asked.
