Change blindness refers to a striking limitation of human perception in which observers fail to notice substantial alterations to a visual scene, provided the change occurs ① during a brief disruption such as an eye movement or a momentary obstruction. In a now-famous demonstration, researchers showed ② participants two versions of a photograph in alternation, separated by a short blank screen, and asked them to identify what had changed. Even when an entire building disappeared or a person's clothing shifted color, many viewers stared at the picture without detecting ③ anything unusual. This phenomenon occurs because visual attention, rather than passively recording every detail like a camera, actively selects only a narrow subset of information for processing at any given moment. Whatever falls outside that narrow spotlight represents ④ only sparsely, if at all, leaving it vulnerable to being overwritten without notice. Consequently, change blindness demonstrates that our impression of a rich, complete visual world is, to a surprising extent, an illusion constructed ⑤ by the mind, not a faithful record of external reality.

Imagine two travelers preparing for the same trip: one refuses to fly after watching news coverage of a recent plane crash, while the other books a flight without hesitation. Statistically, air travel remains far safer than driving the same distance by car, yet vivid, emotionally charged images tend to dominate human judgment more powerfully than dry statistics ever could. This tendency, in which people estimate how likely an event is based on _______________, quietly shapes countless everyday decisions. News broadcasts that repeatedly feature rare disasters can leave viewers convinced that such events are common, even though official records clearly show the opposite. Advertisers and politicians alike exploit this pattern, knowing that a single striking anecdote often persuades audiences more effectively than pages of careful statistics ever manage to.

In the late nineteenth century, the psychologist Hermann Ebbinghaus undertook a rigorous investigation of forgetting by serving as his own experimental subject. He memorized thousands of meaningless three-letter syllables so that prior knowledge could not skew his results. After learning each list to perfection, he tested his retention at intervals ranging from twenty minutes to a month later. He recorded how many repetitions were required to relearn the material each time. The resulting curve revealed a consistent pattern: _______________. Roughly half of the acquired information vanished within the first hour alone. Yet whatever survived that initial plunge tended to persist for much longer periods. Ebbinghaus further found that distributing study sessions across several days produced better retention than cramming the same repetition into one sitting. This finding, now central to modern learning theory, implies that revisiting material shortly before it would otherwise be forgotten interrupts the decline of the forgetting curve.

Working memory refers to the mental workspace in which information is temporarily held and manipulated while a person performs a cognitive task. Such tasks include solving an arithmetic problem, following a rapid conversation, or holding a phone number in mind before dialing it. In the mid-twentieth century, the psychologist George Miller proposed that this workspace could accommodate roughly seven discrete items. His claim proved so influential that it became widely known as the magic number seven. Subsequent research, however, revealed that Miller's estimate was somewhat generous, since it failed to account for the complexity of the material being remembered. Nelson Cowan later argued that when rehearsal strategies are prevented and attention is tightly controlled, _______________. This discrepancy suggests that what earlier studies had measured was not raw storage capacity itself but a hybrid quantity inflated by clever strategies. Contemporary psychologists therefore distinguish between the fixed limit of working memory and the flexible techniques that allow individuals to transcend that limit.

A cotton plant that manufactures its own insecticide sounds like science fiction, yet it has been growing in fields around the world for decades. Scientists achieved this by isolating a gene from a soil bacterium that produces a protein toxic to specific insect pests but harmless to humans, then inserting that gene into the plant's own genome so that every cell manufactures the protective protein. _______________. Supporters point to yield increases and reduced pesticide spraying documented across millions of hectares, while critics worry about weeds and insects evolving resistance to these built-in defenses over time, much as bacteria evolve resistance to antibiotics. Regulatory agencies in most countries now require extensive testing before a genetically modified crop reaches the market, evaluating everything from its nutritional content to its potential effects on nearby ecosystems.

Labeling theory approaches deviance not as a fixed property of certain acts, but as a social process created when powerful groups attach a negative label to a person's behavior. According to this view, nearly everyone breaks minor rules at some point, yet only some individuals are singled out, caught, and formally branded as delinquents or criminals. Sociologist Howard Becker argued that this label often becomes a master status, a single identity that overshadows every other trait a person has. Once labeled, an individual may find legitimate opportunities closing off, pushing them toward _______________. This process, sometimes called secondary deviance, illustrates how social reaction can produce the outcome it claims merely to describe.

When people look back on a multi-day journey, they rarely recall every hour with equal clarity; instead, memory tends to compress the entire experience into just a few representative moments. Psychologists have found that two points carry disproportionate weight in this process: the single moment when emotion reached its highest intensity, and whatever happened right before the experience concluded. (A) Even though both hikers faced comparable hardship overall, the second is far more likely to remember the journey fondly, simply because the trip ended pleasantly. This pattern reveals that overall satisfaction is not calculated as an average of every experienced moment, but is shaped disproportionately by whichever moments felt most intense and by however the experience happened to end. (B) The first finishes with a grueling, rain-soaked final climb, while the second enjoys a calm, scenic descent on the last afternoon despite having endured an equally difficult ascent earlier in the trip. (C) Consider two hikers who complete an identical five-day trek.

Sociologist Mark Granovetter challenged a common assumption when he found that job seekers were more likely to hear about new opportunities from casual acquaintances than from close friends and family. (A) Weak ties, precisely because they connect otherwise separate networks, transmit novel information more efficiently than the redundant, overlapping ties within a tightly bonded group. (C) This finding, published as the strength of weak ties, rests on a structural insight: close friends tend to belong to the same tight social circle and therefore already share most of the same information. (B) Granovetter's insight has since been applied well beyond job searches, informing research on how innovations spread and how epidemics travel through a population.

The cell then acts as a temporary factory, translating that instruction into an actual protein without ever altering the cell's permanent genetic code. For decades, most vaccines worked by injecting a weakened or inactivated version of a pathogen, coaxing the immune system into recognizing an enemy it had never truly fought. ( ① ) mRNA vaccines take a fundamentally different route, delivering only a short genetic instruction wrapped in a protective lipid capsule, one that tells the body's own cells how to manufacture a single harmless piece of a virus's outer surface protein. ( ② ) Once those cells display the fragment, the immune system learns to recognize it as foreign and builds a defense, without ever having encountered the actual pathogen. ( ③ ) Because the vaccine contains no live virus and cannot alter a cell's own DNA, developers can redesign the genetic instructions within weeks whenever a pathogen mutates. ( ④ ) This is far shorter than the years-long process required for traditional vaccines. ( ⑤ ) This speed, first proven on a global scale during a recent pandemic, has convinced many researchers that the same platform could eventually be adapted to fight diseases far beyond infectious illness, including certain cancers.

주어진 문장: This experiment shows that consumers do not simply weigh money saved against money spent, but react to the very presence or absence of a price tag itself. Classical economic theory assumes that consumers evaluate every price change in the same rational way, weighing marginal benefit against marginal cost regardless of the absolute numbers involved. ( ① ) Behavioral economists, however, have discovered a striking exception: the moment a price drops to exactly zero, people's judgment shifts in a way that ordinary discounting cannot explain. ( ② ) In a well-known laboratory experiment, participants chose between two chocolates, one of higher quality priced at a small fee and one of lower quality offered for free. ( ③ ) When both prices were merely reduced by the same amount, most participants still preferred the higher-quality option. Yet once the cheaper chocolate's price was lowered to zero, the majority abruptly switched their preference, even though the price gap between the two options had not actually changed. ( ④ ) Researchers explain this reversal by noting that a free item carries no perceived risk of loss, which makes it feel disproportionately attractive compared with any option that still requires payment, however small. ( ⑤ )
