1 . When you ask people to judge others by their speech, a trend emerges: Listeners dislike disfluency. Slow talkers producing loads of ums and pauses(停顿)are generally perceived as less charming. But science tells us there may be even more to disfluency.
Disfluencies do not occur in arbitrary positions in sentences. Ums typically occur right before more difficult or low-frequency words. Imagine you’re having dinner with a friend at a restaurant,and there’re three items on the table: a knife, a glass, and a wine decanter(醒酒器). Your friend turns to you and says, “Could you hand me the...um...” What would you assume they want? Since it’s unlikely that they will hesitate before such common words as knife, and glass, chances are you’ll pick up the decanter and ask, “You mean this?”
This is exactly what we demonstrated through controlled eye-tracking studies in our lab. Apparently, listeners hear the um and predict that an uncommon word is most likely to follow.Such predictions, though, reflect more than just simple association between disfluencies and difficult words; listeners are actively considering from the speaker’s point of view. For example, when hearing a non-native speaker say the same sentence but with a thick foreign accent, listeners don’t show a preference for looking at low-frequency objects. This is probably because listeners assume non-native speakers may have as much trouble coming up with the English word for a common object, like a knife, as for unusual ones and can’t guess their intention.
In another experiment, listeners were presented with an atypical speaker who produced disfluencies before simple words and never before difficult words. Initially, participants displayed the natural predictive strategy: looking at uncommon objects. However, as more time went by, and they gained experience with this atypical distribution of disfluencies, listeners started to demonstrate the contrary predictive behavior: They tended to look at simple objects when hearing the speaker say um.
These findings represent further evidence that the human brain is a prediction machine: We continuously try to predict what will happen next, even though not all disfluencies are created equal.

2 . Every decision we make is arrived at through hugely complex neurological processing. Although it feels as though you have a choice, the action that you ‘decide’ to take is entirely directed by automatic neural activity. Brain imaging studies show that a person’s action can be predicted by their brain activity up to 10 seconds before they themselves become aware they are going to act. Multiple neuroscientific studies show that even those important decisions that feel worked out are just as automatic as knee-jerk reactions (膝跳反应) (although more complex).
Decision-making starts with the amygdala: a set of two almond-shaped nuclei (杏仁状核) buried deep within the brain, which generate emotion. The amygdala registers the information streaming in through our senses and responds to it in less than a second, sending signals throughout the brain. These produce an urge to run, fight, freeze or grab, according to how the amygdala values various stimuli.
Before we act on the amygdala’s signals, however, the information is usually processed by other brain areas, including some that produce conscious thoughts and emotions. Areas concerned with recognition work out what’s going on, those concerned with memory compare it with previous experiences, and those concerned with reasoning, judging and planning get to work on constructing various action plans. The best plan—if we are lucky—is then selected and carried out. If any of this process goes wrong, we are likely to hesitate, or do something silly.
The various stages of decision-making are marked by different types of brain activity. Fast (gamma)waves, with frequencies of 25 to 100 Hz, produce a keen awareness of the multiple factors that need to be taken into account to arrive at a decision. If you are trying to choose a sandwich, for instance, gamma waves generated in various cells within the ‘taste’ area of the brain bring to mind and compare the taste of ham, hummus, wholemeal, sourdough, and so on. Although it may seem useful to be aware of the full range of choice, too much information makes decision-making more difficult, so irrelevant factors get dismissed quickly and unconsciously.
After this comparison stage, the brain switches to slow-wave activity (12 to 30 Hz). This extinguishes most of the gamma activity, leaving just a single ‘hotspot’ of gamma waves which marks the chosen option.
Although there is no ‘you’ outside your brain to direct what it’s doing, you can help it to make good decisions by placing yourself in a situation which is likely to make the process run more smoothly. Doing something that is physically or mentally stimulating before making a decision will help your brain produce the initial gamma waves that generate awareness of the competing options. Getting over-excited, on the other hand, will prevent the switch to the slow brainwaves, making it much harder to single out a choice.

3 . One of the curious things about social networks is the way that some messages, pictures, or ideas can spread like wildfire while others that seem just as catchy or interesting barely register at all.
Before you go deep into the puzzle, consider this: If you measure the height of your male friends, for example, the average is about 170 centimeters. You are 172 and your friends are all about the same height as you are. Indeed, the mathematical concept of “average” is a good way to capture the nature of this data set.
But imagine that one of your friends was much taller than you. This person would dramatically skew the average, which would make your friends taller than you, on average. In this case, the “average” is a poor way to capture this data set.
Exactly this situation occurs on social networks. On average, your coauthors will be cited more often than you, and the people you follow will post more frequently than you, and so on.
Now Lerman from University of Southern California has discovered a related paradox, which they call the majority illusion. They illustrate this illusion with an example. They take 14 nodes linked up to form a small network. They then color three of these nodes and count how many of the remaining nodes link to them in a single step.
In one situation, the uncolored nodes see more than half of their neighbors as colored. This is the majority illusion — the local impression that a specific feature is common when the global truth is entirely different.
So how popular is it in the real world? It’s found out that the majority illusion occurs in almost all network scenarios. “The effect is largest in the political blogs network, where 60% of nodes will have majority active neighbours, even when only 20% of the nodes are truly active,” says Lerman.
It immediately explains many interesting phenomena. For a start, it shows how some content can spread globally while other similar content does not — the key is to start with a small number of well-connected early adopters fooling the rest of the network into thinking it is common. The affected nodes then find it natural to follow the trend. A real spread finally comes into being.
But it is not yet a marketer’s charter. For that, marketers must first identify the popular nodes that can create the majority illusion for the target audience. These influencers must then be persuaded to adopt the desired behavior or product, which is essential to the prospect of the marketing plan.

4 . It seemed interesting that on the eve of Prime Minister Narendra Modi’s departure for France, the Indian and French governments issued similar statements on the prospects of an agreement on the purchase of the Rafale aircraft: that no single deal should be allowed to overshadow the Prime Minister’s visit. Indeed, India-France relations are much bigger than any one contract; they represent the cultural affinityl (密切关系) and historic relations between two vibrant (醒目的) democracies. The items on the Prime Minister’s agenda reflected the range of commonalities — from the preservation of ancient architecture to the development of Puducherry and Chandigarh as smart cities; from the construction of semi-high-speed railway lines to cooperation on a space mission to Mars; from discussing anti-terror training to tackling climate change through renewable technologies and a robust nuclear partnership. The economic aspect of the relationship has been ignored for too long. Although more than a thousand French companies have a total investment of about $20 billion in India, bilateral trade is worth just $8 billion. While all this deserved attention, it was disappointing that the Prime Minister put the spotlight back on defence ties by making a surprise announcement on the purchase of 36 Rafale aircraft as the highlight of his talks with President Francois Hollande. If the outright purchase was a crucial military necessity, it could have been discussed a few weeks before or after the visit, as a political push for the deal was secondary to the technical specifications and delivery requirements. Moreover, the deal, which involves purchasing products off the shelf abroad, detracts from Mr. Modi’s “Make in India” initiative (主动性).
The breakthrough on the Areva nuclear equipment deal, on the other hand, shows the positive outcome of Mr. Modi’s and Mr. Hollande’s political push, combined with a “Make in India” twist. As in the case of Indo-U.S. nuclear negotiations, Mr. Modi and Mr. Hollande decided to clear the logjam by splitting the problem into different silos — allowing for separate mechanisms for the pricing issues and for the technical and legal aspects. The supplementary deal involving Areva and L&T producing heavy forging metal casing for nuclear reactors is an important step in localising some of the expensive parts. During his visit to Canada, where he hopes to sign a deal for uranium supplies, Mr. Modi means to take forward his plan to increase nuclear energy production. Given this objective, it may be useful for him to round off the visit by discussing his nuclear energy plans in Germany as well, which is now winding down on nuclear power but is at the cutting edge of nuclear safety research for the European Pressurised Reactors that are being considered for India.

5 . How to Feel Connected
It's easy to feel disconnected from what is going on around you in today's fast-paced world.
Consider why you feel disconnected. Knowing what is making you feel disconnected can help you choose the best ways to address it.
Interact with people in person. Technology is a great way to stay in touch, but sometimes you need to spend time with other people in person.
Your loved ones could feel shy, so you may never know how to improve your relationship unless you ask the right questions. Asking them to open the doors can give you some insight on what you can do. Learning this information can help to strengthen your bond.
Show your commitment to them. Simply showing up and being there for your loved ones says a lot about how much you value your relationships. Putting in the time shows them that you are committed and want to stay connected.
Show appreciation. A simple “thank you” goes a very long way. Unfortunately, it is something that people who are close often take for granted. Telling someone you appreciate their time, love, and efforts can strengthen your bond and help you to become more connected.
| A．Ask others what they need from you. |
| B．Sometimes you can feel isolated and distant from the ones you love. |
| C．Be brave to express your love. |
| D．Reach out to people to schedule a time to get together. |
| E．Attending family events, or simply visiting someone once a week can help to strengthen your relationship and keep it strong. |
| F．Targeting your efforts toward those issues allows you to close that distance more effectively. |
| G．You can have a gift delivered to friends on special occasions. |
