2 . Relatives of starfish, brittle stars (海蛇尾) spend most of their time hiding under rocks in the ocean or digging in the sand. These shy marine creatures have no brain to speak of—just nerve cords running down each of their five wiggly arms, which join to form a nerve ring near their mouth.
“There’s no processing center. Each of the nerve cords can act independently. Instead of a boss, it’s like a committee. That seems to be enough to learn by association,” said lead author Julia Notar. This type of leaning involves associating different stimuli via a process called classical conditioning (条件反射).
Classical conditioning has been demonstrated in a handful of previous studies in starfish. But brittle stars and similarly brainless starfish have not been tested.
To find out if brittle stars have the ability of learning, the researchers put 16 black brittle stars in individual water tanks and used a video camera to record their behavior. Half the brittle stars were trained by dimming the lights for 30 minutes whenever the animals were fed. Every time the lights went out, the researchers would put a bit of shrimp in the tanks, placed just out of reach. The other half got just as much shrimp and also experienced a 30-minute dark period, but never at the same time—the animals were fed under lit conditions.
Whether it was light or dark, the animals spent most of their time hiding behind the filters in their tanks, only coming out at mealtime. But only the trained brittle stars learned to associate darkness with food. They didn’t need to smell or taste the shrimp to react.
Notar said the results are exciting because classical conditioning hasn’t really been shown definitively in this group of animals before. “Knowing that brittle stars can learn means they’re not just robotic scavengers (清道夫) cleaning up the ocean floor,” Notar said. “They’re potentially able to expect and avoid predators (捕食者) or expect food because they’re learning about their environment.”

How long does it take to type without looking at the keyboard?An average student without learning differences will learn to touch type within eight to ten hours. They may be touch typing at a very slow speed (8-15 words per minute).
Is it bad to look at the keyboard when typing?Yes. Not only does it prevent you from practicing your fingering, but it also slows you down and makes you type less accurately. It's far more difficult to notice mistakes when you're not looking at the screen.
How do you get faster at typing?The most important technique to learn to type faster is touch typing. This is a technique based on developing muscle memory for your fingers.
How can I learn to type correctly?Focus on accuracy rather than speed. Use the entire keyboard correctly. Learn some keyboard shortcuts. Practice every day.
How do I increase my typing speed?Arrange your fingers properly. The most important step in improving your typing speed is ensuring that you place your fingers correctly on the keyboard. Rest the index finger (食指) of your left hand on the “F” key and the index finger of your right hand on the “J” key.

6 . Living with self-doubt can be very challenging. It limits potential and breaks morale. Here are some strategies that you can use to overcome self-doubt.
● Self-compassion (自我同情) is the key.
We often doubt ourselves when we have the fear of losing, but that is a grave mistake we make. Everyone will make mistakes at some part in their lives, but we have to grow from those mistakes and transform them into a lesson.
Start your day with some positivity, look at yourself in the mirror, and make some positive affirmations (肯定).
● Reflect back to your past achievements.
●
“You are known by the company you keep”, is one of the best sayings to explain this strategy. We should be surrounded by people that support and love us, not people that constantly make us doubt ourselves. Good people will help you recover from negative and stressful situations.
●Seek professional help if necessary.
● Start journaling events.
In life, there will come many events that we are thankful for, especially our achievements.

D.Always be in the company of supportive people. |
