Writer JRR Tolkien took bits of his favourite real-world languages and spliced them together. Listen carefully to the dialogue in the forthcoming movie of Return of the King and you might recognise some old English, a Welsh lilt here and there, and even some Finnish. "They are invented languages but they are completely logical and they're linguistically sound," says Fred Hoyt, a linguistics researcher at the University of Texas in Austin who also teaches a course on Elvish.

"Change has occurred so rapidly for our species that now we are equipped with brains that are super sensitive to threat but also super capable of planning, thinking, forecasting and looking ahead," said Ahmad Hariri, a professor of psychology and neuroscience at Duke University. "So we essentially drive ourselves nuts worrying about things because we have too much time and don't have many real threats on our survival, so fear gets expressed in these really strange, maladaptive ways." Dr. Hariri studies the amygdala, an almond-shaped structure that has been called the seat of fear (there's one in each hemisphere of the brain). But it's really the seat of anticipation. The amygdala primes you to react - your pulse quickens, your muscles tense and your pupils dilate - even before other parts of your brain can figure out if you need to be scared or not. Nowadays, our amydalas can be overactive, thanks to 24/7 awareness of disasters around the world and/or stress/instability in one's personal and professional life. Remaining in this state of wary hypervigilance can contribute to issues like social anxiety, hypochondria, post-traumatic stress disorder, insomnia and all manner of phobias. It also plays a role in racial and religious intolerance because fearful people are more inclined to cling to the familiar and denigrate the unfamiliar. If you can sense and appreciate your fear - be it of flying, illness or social rejection - as merely your amygdala's request for more information rather than a signal of impending doom, then you are on your way to calming down and engaging more conscious, logic-dominated parts of your brain. At that point, you can assess the rationality of your fear and take steps to deal with it.

This article talks about how even though learning how to program a computer seems like learning a new language, computer language is actually processed through a different area of the brain than when language is processed. It says that it activates the multiple demand network, which is also activated by complex cognitive tasks such as solving math problems or crossword puzzles. However, it appears to rely on different parts of the network than math or logic problems do, which suggests that coding does not precisely replicate the cognitive demands of mathematics either. The article says that researchers didn't find any regions that appear to be exclusively devoted to programming. They also suggest that understanding computer code cannot be categorized as a language-based or math-based skill. Instead, they think it might require a combination of both skills, even though the brain regions don't reflect it.

This article talks about a study that was conducted by MIT linguistics professors and a group from Carleton University that explored the phenomenon of why children mix up the words "and" and "or." Linguists say that children use almost entirely the same approach as adults when it comes to evaluating potentially ambiguous sentences, by testing and "strengthening" them into sentences with more precise meanings, when disjunction and conjunction ("or" and "and") are involved. However, they found that children do not test how a sentence would change if "and" was directly substituted for "or." On the other hand, adults compute "scalar implicatures," which is a technical phrase for thinking about the implications of the logical relationship between a sentence and its alternative. The research team conducted the study's experiment by testing 59 English-speaking children and 26 adults. The children ranged in age from 4 months to 6 years. The linguists gave the subjects a series of statements along with pictures, and asked them to say whether the statements were true or false. The results suggest that children are computing scalar implicatures when they evaluate the statements, but they largely do not substitute disjunctions and conjunctions when testing out the possible meaning of sentences, as adults do. In general, the researchers observed, across languages, and for children and adults alike, when you take 'and' out of the space of alternatives, "or" becomes "and."

In the last half century, much effort has been placed into teaching animals, primarily apes, a basic language. However, successes have been limited: animals using signs to obtain things in which they were interested, for instance. But no animal has yet acquired the linguistic capability that children have already in their third year of life. Here are some things that differentiate humans from animals: 1. The fact that animals don't ask "why?" shows they don't aspire to knowledge and are incapable of justification. 2. The inability of animals to use negation shows they lack basic logical abilities. 3. Another essential characteristic of human language is its normativity-namely, the fact that there are right and wrong uses of a word or phrase. Animals lack this capacity.
