Psychologists have long studied a mechanism called the variable reward schedule, in which rewards ①arrive unpredictably rather than after every single action. Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. When someone posts a photo, they cannot predict exactly when likes will appear, nor ②how many they will eventually receive. This uncertainty triggers a small burst of dopamine each time the phone ③is checked, regardless of whether the result is disappointing or thrilling. Consequently, users often refresh their feeds compulsively, ④hoping the next check will finally bring a satisfying reward. What makes this troubling is that technology companies deliberately designed notification systems using insights borrowed from gambling research, rather than ⑤stumble upon them by accident.

Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. This theory explains that every habit begins with a cue, a signal that tells the brain to start an automatic behavior. The brain then performs a routine, which is the action itself, whether physical or mental. Finally, the brain receives a reward, a positive feeling that makes it want to repeat the same behavior. 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 ___________. Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.

An echo chamber refers to an online environment where people are mainly exposed to opinions that already match their own beliefs. This phenomenon occurs because social media algorithms tend to recommend content similar to what users have previously liked or shared, gradually narrowing the range of perspectives they encounter. As a result, individuals inside an echo chamber rarely engage with viewpoints that challenge their existing assumptions, which allows their original beliefs to grow increasingly extreme over time. For example, someone who frequently reads articles supporting one political party may begin to see the opposing party as entirely unreasonable, having never seriously considered its arguments. Political polarization, a significant issue in many countries today, is often linked to this pattern of selective exposure. Breaking out of an echo chamber requires ___________.

Many teenagers check their social media accounts dozens of times a day, worried that they might miss something important happening among their friends. This anxiety, known as FOMO, or the fear of missing out, arises when people believe that others are enjoying experiences from which they themselves are excluded. For example, a student scrolling through photos of a party she was not invited to may suddenly feel a wave of loneliness and regret, even though the event has already ended. Constantly refreshing feeds to avoid missing such updates, however, makes it difficult to concentrate on schoolwork or conversations happening in the present moment. Moreover, this endless comparison with curated highlights of other people's lives tends to deepen feelings of anxiety rather than relieve them. Therefore, students should learn to ___________.

Researchers who study teenagers have found a strong link between how well students sleep and how well they perform in school. Students who sleep fewer than seven hours a night tend to score lower on tests of memory and attention than those who sleep eight or nine hours, even when the two groups study for the same number of hours. One explanation is that sleep plays an active role in learning: during certain stages of sleep, the brain replays and strengthens information encountered during the day, _______________. When sleep is cut short, this consolidation process is interrupted before it can finish, so material that seemed well understood the night before often feels unfamiliar the next morning. For this reason, some schools have begun rethinking early start times, reasoning that an extra hour of sleep might do more for test scores than an extra hour of studying ever could.

Smart speakers have quietly become a fixture in many households, responding to spoken requests for weather updates, music, or kitchen timers. Because these assistants improve by learning from millions of interactions, they gradually become better at recognizing regional accents and casual phrasing that once confused them. Still, _______________. Engineers continue to refine these systems, but many admit that truly natural conversation remains one of the hardest goals in the entire field of artificial intelligence.

Goal-setting theory has influenced not only classrooms but also workplaces around the world. (A) Many companies now train managers to set specific quarterly targets rather than simply asking employees to 'do their best.' (B) As a result, employees often report clearer priorities and a stronger sense of accomplishment. (C) These targets typically include measurable numbers, such as sales figures or project deadlines.

A growing number of health apps now track steps, sleep, and heart rate throughout the day, quietly building a detailed picture of a user's physical condition without requiring a single visit to a doctor's office. (A) Doctors caution, however, that these apps are designed to detect patterns, not to diagnose illness, and that a worried user should always confirm any alarming reading with a professional. (B) For people living far from specialists or unable to afford frequent checkups, this kind of constant monitoring can feel like a genuine safety net. (C) By comparing this stream of data against patterns drawn from millions of other users, the app's algorithm can flag early warning signs, such as an irregular heartbeat, long before the person notices anything unusual.

This built-in schedule does not simply respond to the clock on the wall; it is shaped directly by light itself. Every cell in the human body follows an internal timer known as the circadian rhythm, a roughly twenty-four-hour cycle that governs when we feel alert and when we feel drowsy. ( ① ) This clock is regulated primarily by a tiny cluster of neurons in the brain that responds to light entering through the eyes. ( ② ) When morning sunlight strikes the retina, the cluster signals the body to suppress sleep hormones and raise body temperature, preparing us for activity. ( ③ ) As evening approaches and light fades, the same mechanism triggers the release of melatonin, a hormone that promotes drowsiness. ( ④ ) Because this rhythm evolved around the natural cycle of day and night, modern habits such as staying indoors under artificial light or working night shifts can push the internal clock out of sync with the external environment. ( ⑤ ) Such misalignment does not simply cause tiredness; it has also been associated with digestive problems and reduced concentration, suggesting that timing matters as much as total sleep hours.

주어진 문장: In short, Fogg's model reminds us that ease of action, not sheer willpower, drives lasting behavior change. Many people believe that building a new habit requires strong willpower or motivation. ( ① ) However, psychologist BJ Fogg argues that habits form more easily when a behavior itself becomes simple to perform. ( ② ) His theory, called the Fogg Behavior Model, states that a behavior happens only when motivation, ability, and a prompt occur together. When motivation is low, the task must be made extremely easy, or it will not happen at all. ( ③ ) For instance, a person who wants to exercise daily succeeds more often by committing to one push-up than to a long workout. Fogg calls this idea the law of least effort, since people naturally choose the option requiring the least energy. ( ④ ) A student who wants to read more might leave a book open on the desk rather than setting a vague goal. By lowering the required effort, people reduce the ability barrier and make steady action far more achievable. ( ⑤ )
