Coaches have traditionally focused athlete preparation on training volume and nutrition, but a growing body of research ① suggests that sleep deserves equal attention. During deep sleep, the body releases growth hormone, a substance essential for ② repairing muscle tissue damaged during intense training, while the brain consolidates motor skills practiced earlier that day into more stable, efficient patterns. Athletes who sleep fewer than seven hours a night have been shown ③ suffering more injuries, slower reaction times, and reduced accuracy compared to well-rested peers performing the identical drills. Frequent travel across time zones compounds this challenge considerably, since jet lag can ④ disrupt an athlete's natural sleep-wake cycle for several days after a long flight. In response, many professional teams now employ sleep specialists ⑤ who design travel schedules, control bedroom lighting and temperature, and even adjust competition start times when possible.

Many people struggling to fall asleep in noisy environments turn to white noise machines, devices that emit a ① chaotic, uniform sound covering a broad range of frequencies. The appeal lies in a phenomenon called auditory masking, in which a constant background sound makes sudden noises, such as a slamming door, ② less noticeable to the sleeping brain. Without this masking effect, an abrupt change in sound is far more likely to trigger a brief awakening, even if the sleeper does not ③ consciously remember it the next morning. Studies comparing sleep in quiet rooms with sleep alongside white noise have found that participants using white noise experienced fewer of these brief awakenings and reported feeling more ④ rested. However, researchers caution that the benefit depends heavily on volume and consistency, since noise that is too loud or that varies unpredictably can itself become a source of ⑤ disruption rather than a remedy.

Influencer marketing has become one of the most powerful tools that companies use to reach young consumers. Unlike traditional advertisements, which often feel distant and impersonal, posts created by influencers seem more like advice from a trusted friend. This sense of closeness, built through years of sharing daily life online, makes followers more willing to trust product recommendations than ordinary commercials. For example, a skincare brand promoted by a popular lifestyle influencer can sell out within hours simply because her audience believes her opinions are honest. However, this trust can be exploited when influencers promote products they have never actually tried. As a result, several countries now require influencers to clearly disclose paid partnerships before posting sponsored content. Consumers are becoming more cautious, checking whether reviews are sponsored before making a purchase. In the end, influencer marketing ___________.

A navigation app calculating a route rarely relies on distance alone; instead, it constantly weighs real-time traffic reports, past congestion patterns, and even data from other drivers' phones currently on the road. This flood of information allows the app to reroute a driver away from a sudden accident within seconds. The convenience comes at a cost that few passengers consider, however. When thousands of drivers are simultaneously redirected onto the same shortcut, _______________, arguing that an algorithm optimizing for individual convenience can end up creating a new, entirely different problem for the wider community.

Opening most camera apps today reveals a row of filters that can smooth skin, brighten eyes, and reshape a jawline before a photo is even taken. What began as a playful novelty has become a default setting for many users, subtly adjusting nearly every selfie posted online. Psychologists have grown concerned about a specific consequence of this shift: _______________. Some social media platforms have responded by labeling heavily edited photos or banning certain filters that alter body shape.

When Mina was a freshman, she often spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study in which children could eat one marshmallow immediately or wait for two. Researchers found that children who waited longer showed better academic performance and self-control years later. This ___________ is known as delayed gratification. Inspired by the study, Mina began saving half of her allowance each week instead of spending it all on snacks.

Software development teams are especially known for missing their own deadlines by wide margins. (A) A team asked to estimate a new project usually imagines everything proceeding smoothly, without bugs, meetings, or unexpected requests. (B) To avoid repeating this mistake, some teams now review how long their last three similar projects actually took before setting a new deadline. (C) Because this imagined version rarely matches reality, the original deadline is missed almost every time, often by weeks or months.

This dopamine-driven cycle explains why so many people check their phones dozens of times throughout the day without even realizing it. (A) Neuroscientists have found that the anticipation of a possible reward, not the reward itself, produces the strongest dopamine response in the brain. (B) In other words, the brief moment of waiting to see how many likes a post receives can feel more exciting than the actual number that appears. (C) Because this anticipation is so powerful, technology designers intentionally build delays and randomness into how notifications are delivered.

Implementation intentions have become one of the most widely studied tools in behavioral psychology for helping people reach their goals. (A) Unlike a vague goal such as "I will exercise more," an implementation intention specifies both the situation that triggers the behavior and the exact action that follows. (B) Because the decision has already been made in advance, people no longer need to rely on willpower at the critical moment when the temptation to skip arises. (C) For example, a person might decide, "If it is seven in the morning, then I will put on my running shoes immediately," rather than simply hoping to find time to exercise.

주어진 문장: This is why many coaches encourage athletes to keep their pre-game rituals exactly the same, even when circumstances change. Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. ( ① ) This theory explains that every habit begins with a cue, a signal that tells the brain to start an automatic behavior. ( ② ) The brain then performs a routine, which is the action itself, whether physical or mental. ( ③ ) Finally, the brain receives a reward, a positive feeling that makes it want to repeat the same behavior. ( ④ ) For example, a notification sound can act as a cue that leads a student to check a phone, and the relief from boredom becomes the reward. Similarly, opening a refrigerator out of habit rather than hunger shows how a routine can run without conscious thought. Because this loop operates automatically, breaking a bad habit requires changing the routine while keeping the same cue and reward. ( ⑤ ) Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.
