Working memory refers to the mental workspace in which information ①is 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 ②become 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 ③being remembered. Nelson Cowan later argued that when rehearsal strategies ④are prevented and attention is tightly controlled, genuine capacity hovers closer to four items rather than seven. This discrepancy suggests that what earlier studies had measured was not raw storage capacity itself but a hybrid quantity ⑤inflated 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.

The discovery of CRISPR gene-editing technology gave scientists a tool ①precise enough to correct a single mistaken letter in the human genome, raising hope for curing inherited diseases that have resisted treatment for generations. Yet the same precision that makes CRISPR so promising also makes it ②dangerous in the wrong hands. Editing a gene in a sperm, egg, or early embryo does not simply change one patient; it alters the genetic code passed down to every future generation, a decision no single person should be allowed to make ③alone. Scientific organizations around the world have therefore drawn a careful line, ⑤permitting gene editing to treat disease in existing patients while ④permitting any edit that would be inherited by their descendants. Critics worry, however, that as the technology becomes cheaper and more widely available, this line will become harder to enforce than it is to draw.

A small bakery once sold a basic loaf of bread for three dollars and a premium loaf for six dollars, and most customers, uncertain about the added value of the pricier option, simply bought the ①cheaper one. The owner then introduced a third option: a slightly larger premium loaf priced at seven dollars, one that was clearly ②inferior to the six-dollar loaf in terms of value for money. Almost nobody chose the new seven-dollar loaf, yet sales of the six-dollar loaf ③fell sharply, because it now appeared to be an obvious bargain when placed beside the inferior newcomer. This pattern, confirmed across countless pricing experiments in other markets, demonstrates that people ④rarely judge options in isolation; instead, they evaluate choices relative to whatever alternatives happen to be nearby. Businesses have since learned to design such decoys deliberately, not expecting them to be purchased at all, but hoping they will make a specific target option look far more ⑤attractive by comparison.

Cognitive load theory begins from the premise that working memory, the mental workspace in which incoming information is temporarily held and manipulated, can accommodate only an ①unlimited number of novel elements at any given moment, in stark contrast to the comparatively vast capacity of long-term memory. When instructional materials introduce more interacting elements than this narrow workspace can simultaneously process, learners experience what theorists call cognitive ②overload, a condition under which comprehension deteriorates and errors multiply regardless of how motivated the learner might be. Because much of this burden arises not from the intrinsic difficulty of the subject matter itself but from the manner in which information is presented, instructional designers can substantially ③reduce unnecessary strain by eliminating redundant explanations, aligning visual and verbal elements so that learners need not mentally integrate scattered sources, and gradually ④withdrawing guidance as competence develops. Ignoring these principles, by contrast, risks ⑤overwhelming novices with demands that exceed their processing capacity, however well-organized the underlying content may be.

Dual coding theory, first proposed to explain why certain kinds of information are remembered more readily than others, holds that the mind processes verbal and visual material through two partially independent channels rather than a single unified system. According to this account, words and other linguistic symbols are encoded primarily through a verbal channel that represents meaning in an abstract, sequential form, while pictures and concrete objects are encoded through an imagery channel that preserves spatial and perceptual detail. When information engages both channels simultaneously, as when a textbook pairs a written explanation with an accompanying diagram, _______________. This redundancy explains the well-documented picture superiority effect, whereby concrete, easily visualized words tend to be recalled more accurately than abstract terms that resist mental imagery. Consequently, dual coding theory has profound implications for instructional design, suggesting that combining carefully chosen visuals with concise verbal explanations can strengthen students' long-term retention of complex material.

Classical economic theory long assumed that decision makers gather all relevant information, calculate every possible outcome, and select the single option that maximizes their benefit. (A) Herbert Simon, however, questioned this assumption, arguing that human beings operate under real constraints of time, knowledge, and mental capacity that make such exhaustive calculation practically impossible. (B) Instead of searching endlessly for the theoretically perfect choice, people typically stop once they find an option that seems good enough to meet their immediate needs, a strategy Simon termed satisficing. (C) A shopper comparing refrigerators, for example, rarely examines every model available; she instead sets a few practical criteria, such as price and size, and selects the first appliance that satisfies them adequately. This approach is not a failure of reasoning but rather a sensible adaptation to a world where information is costly and time is genuinely limited. Consequently, models assuming unlimited rationality often fail to predict actual behavior, while frameworks acknowledging these cognitive boundaries offer a far more realistic account of how ordinary decisions are actually made.

Prospect theory proposes that the subjective value of money is not a straight line but a curved function, differing sharply from the assumptions of classical economic models. (A) Understanding this curvature allows economists to predict decisions that a simple, linear model of value could never anticipate. (B) This tendency, known as diminishing sensitivity, explains why a shopper barely notices a ten dollar increase on a two thousand dollar purchase, though the same ten dollars would matter enormously as the price of a meal. (C) In the domain of gains, the function bends downward as amounts increase, and a parallel pattern appears among losses, where the curve bends in the opposite direction, yet sensitivity still fades as the amount grows larger.

Confined in this controlled setting, the organisms grow far faster than they ever would in the wild. Long before humans learned to drill for oil, microorganisms had already mastered the art of converting sunlight and carbon dioxide into stored chemical energy. ( ① ) Modern biofuel research borrows this ability, cultivating algae or engineered bacteria in large tanks. ( ② ) There, they can be coaxed into producing oils and sugars that can be refined into fuel usable in existing engines. ( ③ ) Unlike crops grown for corn-based ethanol, which compete directly with food production for arable land, many algae strains can thrive in shallow ponds, wastewater, or even coastal seawater unsuitable for conventional agriculture. ( ④ ) Engineers have also learned to tinker with the metabolic pathways of these organisms, boosting oil yield far beyond what any wild strain would naturally produce on its own. ( ⑤ ) Despite this progress, producing biofuel at a cost competitive with fossil fuel remains difficult, since harvesting and processing the organisms consumes a substantial share of the energy the fuel itself will eventually provide.

Because no alternative is ever removed, defenders insist that the intervention remains fully compatible with individual liberty. One of the most frequently cited nudge programs involves the redesign of cafeteria layouts to encourage healthier eating among students. ( ① ) Rather than banning unhealthy snacks outright, administrators simply relocate them to less convenient shelves while placing fruit and vegetables within easy reach. ( ② ) Students remain completely free to seek out the relocated items if they wish to do so. ( ③ ) Data collected across numerous schools show that this modest rearrangement increases the selection of healthier options by a meaningful margin, without any accompanying complaints about restricted choice. ( ④ ) Skeptics nonetheless point out that the very effectiveness of such nudges depends on exploiting the same mental shortcuts, such as convenience and visibility, that lead people to make less healthy choices in the first place. ( ⑤ ) Whether this exploitation is ethically troubling or simply a pragmatic use of known psychological tendencies remains a matter of ongoing disagreement.

주어진 문장: Psychologists first documented this delay nearly a century ago, and it has since become one of the most frequently replicated findings in cognitive science. Anyone who has tried to name the ink color of a word like red printed in blue letters knows how surprisingly difficult the task can feel. ( ① ) This everyday struggle, known as the Stroop effect, deserves more attention than casual curiosity grants it, because it reveals something fundamental about how the mind allocates its limited resources. ( ② ) Reading a familiar word is an automatic process practiced so extensively since childhood that it proceeds almost involuntarily, whereas naming a color requires deliberate, controlled attention. ( ③ ) When these two processes point toward conflicting answers, the automatic pathway tends to intrude upon the controlled one, slowing responses and increasing errors. ( ④ ) Educators should not dismiss this delay as a trivial curiosity confined to laboratories, since the same competition between habit and intention underlies far more consequential situations, such as a driver's struggle to resist checking a phone despite knowing the danger. ( ⑤ ) Recognizing how automatic responses can hijack conscious intentions is essential for designing environments, from classrooms to highways, that support rather than undermine our efforts at self-control.
