Social media researchers use the term context collapse ①to describe what happens when a single online post ②reach audiences that would normally remain separate in offline life. In daily interactions, people naturally adjust their tone and content depending on whether they are ③speaking with family, close friends, or professional colleagues. However, a typical social media feed merges these distinct audiences into one undivided crowd, since a single post can simultaneously reach parents, employers, and casual acquaintances. Consequently, users often struggle to decide which version of themselves ④to present, knowing that a joke suitable for close friends might seem unprofessional to a supervisor. This tension forces many users to either self-censor heavily or maintain multiple separate accounts ⑤tailored to different audiences.

Setting a goal such as 'I will study harder' rarely leads to ①meaningful improvement. According to psychologists Edwin Locke and Gary Latham, ②specific and challenging goals produce far better performance than vague or easy ones. This idea, known as goal-setting theory, suggests that ③clear targets direct attention and sustain effort over time. To apply this theory effectively, many educators recommend the SMART framework, which requires goals to be Specific, Measurable, Achievable, Relevant, and Time-bound. For instance, a student following this framework might say, 'I will memorize thirty new words every week for two months.' Because the goal includes a clear number and a deadline, progress becomes easy to ④track and evaluate. Challenging goals also tend to increase motivation, since people often work harder when a target feels meaningfully ⑤easy rather than trivially simple.

A growing number of people are practicing what is now called digital detox, the deliberate decision to stop using smartphones for a set period. Rather than checking notifications every few minutes, participants unplug for a weekend, a week, or sometimes even longer. Numerous studies suggest that this temporary withdrawal produces ①real benefits for both the mind and the body. First, attention spans fragmented by constant notifications gradually ②recover, allowing people to concentrate on single tasks for longer stretches. Second, avoiding screens before bedtime ③worsens sleep quality, since blue light emitted by devices is known to disrupt natural sleep cycles. Third, people freed from their phones often rediscover the pleasure of face-to-face conversations that had been replaced by texting. Critics argue that complete disconnection is impractical in a hyperconnected society, yet even brief, regular breaks appear to ④restore balance. Therefore, scheduling periodic digital detox sessions deserves ⑤serious consideration.

An echo chamber refers to an online environment where people are mainly exposed to opinions that already ①match their own beliefs. This phenomenon occurs because social media algorithms tend to recommend content similar to what users have previously liked or shared, gradually ②narrowing the range of perspectives they encounter. As a result, individuals inside an echo chamber ③frequently 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 ④unreasonable, having never seriously considered its arguments. Political polarization, a significant issue in many countries today, is often linked to this pattern of ⑤selective exposure.

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. 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 experiencing it would have noticed anything unusual. Doctors caution, however, that these apps are designed to detect patterns, not to diagnose illness, and that _______________.

Many people believe that building a new habit requires strong willpower or motivation. However, psychologist BJ Fogg argues that habits form more easily when a behavior itself becomes simple to perform. His theory, called the Fogg Behavior Model, states that ___________. When motivation is low, the task must be made extremely easy, or it will not happen at all. 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. 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.

Have you ever felt a boring class lasted forever while an exciting weekend disappeared in an instant? This common experience reflects what psychologists call the distortion of time perception: ___________. Researchers explain that people who focus intensely on an enjoyable activity process fewer separate moments, so time seems to pass quickly. In contrast, bored or anxious people pay closer attention to each moment, making time feel as though it is dragging.

Many students struggle not with lack of effort but with lack of structure when studying for exams. (A) Once colors are assigned, the student blocks specific hours of the day for each subject, following the same order as a printed timetable. (B) As a result, switching between subjects no longer feels confusing, because each color block signals exactly what should happen next. (C) One student solved this problem by giving each subject a distinct color on a printed weekly calendar before the semester began.

Sleep debt refers to the cumulative gap between the amount of sleep a person needs and the amount they actually get. (A) Unlike a financial debt, however, this deficit cannot simply be repaid with a single long weekend of rest. (B) When someone loses two hours of sleep every night for a week, the body does not treat the shortage as fourteen separate small losses; instead, it accumulates the deficit, and the resulting impairment in attention and mood can resemble that of a person who has been awake for an entire night. (C) Researchers have found that even modest, chronic sleep restriction gradually impairs reaction time and decision-making, often without the affected person noticing the decline. This is because subjective feelings of tiredness tend to plateau after a few days, even as objective performance keeps deteriorating. Consequently, people frequently underestimate how much sleep debt they are carrying until a demanding task suddenly exposes the accumulated cost.

주어진 문장: At first glance, this seems to suggest that Dunbar's theory no longer applies in the digital age. Anthropologist Robin Dunbar proposed a concept now known as Dunbar's number, suggesting that human beings can only maintain about one hundred fifty stable social relationships at any given time. ( ① ) This limit, he argued, comes from the size of the human brain, which restricts how many meaningful connections a person can cognitively manage. ( ② ) In contrast, many social media users today have hundreds or even thousands of online friends and followers, a number far exceeding what Dunbar's research predicts. ( ③ ) However, having numerous digital contacts does not necessarily mean that all of these relationships are close or emotionally supportive. ( ④ ) Most users, when asked, admit that they interact regularly with only a small fraction of their total followers, while the rest remain largely unnoticed. ( ⑤ ) Therefore, Dunbar's number reminds us that genuine, lasting relationships require consistent effort and attention, something that a large online network alone cannot provide.
