Question: Article: This place was darker than I expected, and, in spite of the rain, dirtier. Used to the life of rural Puerto Rico , I had to adjust to the similarly arranged, aggressive two-dimensionality of New York. Everywhere I looked, my eyes met gray and brown straight-edged buildings with sharp corners and deep shadows. Every few blocks there was a cement playground surrounded by chain-link fence. A girl came out of the building next door, a jump rope in her hand, and she hopped over. "Are you Hispanic?" she asked. "No, I'm Puerto Rican." "Same thing. Puerto Rican, Hispanic. That's what we are here." She skipped a tight circle, stopped abruptly, and shoved the rope in my direction. "Want a turn?" "Sure." I hopped on one leg, then the other. "So, if you're Puerto Rican, they call you Hispanic?" "Yeah. Anybody who speaks Spanish." I jumped a circle, as she had done, but faster. "You mean, if you speak Spanish, you're Hispanic?" "Well, yeah. No . . . I mean your parents have to be Puerto Rican or Cuban or something." "Okay, your parents are Cuban, let's say, and you're born here, but you don't speak Spanish. Are you Hispanic?" "I guess so," she finally said. "It has to do with being from a Spanish country. I mean, you or your parents, like, even if you don't speak Spanish, you're Hispanic, you know?" She looked at me uncertainly. But I didn't know. I'd always been Puerto Rican, and it hadn't occurred to me that in New York I'd be someone else. Later, I asked. "Are we Hispanics, Mami?" "Yes, because we speak Spanish." "But a girl said you don't have to speak the language to be Hispanic." "What girl? Where did you meet a girl?" "Outside. She lives in the next building." "Who said you could go out to the sidewalk? This isn't Puerto Rico. Something could happen to you." I listened to Mami's lecture with depressed eyes and the necessary respect. But inside, I quaked. Two days in New York, and I'd already become someone else. It wasn't hard to imagine that greater dangers lay ahead.
Answer: an unavoidable result of movement to a new place

Question: Article: Sensing phantom phone vibrations is a strangely common experience. Around 80% of us have imagined a phone vibrating in our pockets when it's actually completely still. Almost 30% of us have also heard non-existent ringing. Are these signs of madness caused by digital culture? Not at all. In fact, phantom vibrations and ringing indicate a fundamental principle in psychology. Psychologists use a concept called Signal Detection Theory to guide their thinking about the problem of perceptual judgments. Working through the example of phone vibrations, we can see how this theory explains why they are a common and unavoidable part of healthy mental function. When your phone is in your pocket, the world is in one of two possible states: the phone is either ringing or not. You also have two possible states of mind: the judgment that the phone is ringing, or the judgment that it isn't. Obviously you'd like to match these states in the correct way. True vibrations should go with "it's ringing", and no vibrations should go with "it's not ringing". Signal detection theory calls these faithful matches a "hit" and a "correct rejection" But there are two other possible combinations: you could mismatch true vibrations with "it's not ringing" (a "miss"); or mismatch the absence of vibrations with "it's ringing" (a "false alarm"). This second kind of mismatch is what's going on when you imagine a phantom phone vibration. What does that mean in terms of your phone? We can assume that people like to notice when their phone is ringing, and that most people hate missing a call. This means their perceptual systems have adjusted their bias to a level that makes misses unlikely. The unavoidable cost is a raised likelihood of false alarms of phantom phone vibrations. The trade-off between false alarms and misses also explains why we all have to put up with fire alarms going off when there isn't a fire. It isn't that the alarms are badly designed, but rather that they are very sensible to smoke and heat and biased to avoid missing a real fire at all costs. The outcome is a rise in the number of false alarms. These are inconvenient, but nowhere near as inconvenient as burning to death in your bed or office. The alarms are designed to err on the side of caution.
