  Explanation/Reference:

  Previously unknown extrasolar planets-planets outside our solar system-- probably await discovery In archival images taken by the Hubble Space Telescope. A new technique allows astronomers to model the amount and distribution of scattered light produced by young stars suspected of spawning planets and remove that light from images of those stars. Once the glare of the parent stars' light is removed, planets may show up In Images already taken by Hubble's infrared cameras, since heat emitted by planets produces telltale wavelengths of infrared light. In 2008, astronomers using powerful Earth-based telescopes were able to detect three planets orbiting the star HR 8799 that were not previously detected by astronomers who examined infrared Hubble images of the star in 1998. David Lafrentere--a member of the team of astronomers who detected the planets in 2006 --then applied the new technique to those Hubble images and managed to uncover the outermost of the three planets. The others, tying closer to the star, still could not be distinguished against the background of the star's light. Lafrenifre's work has helped reaffirm the importance of maintaining long-term archives, and--because Hubble's infrared cameras record some wavelengths of light that cannot penetrate through the atmosphere to reach Earth's surface- revealed new information about the outermost of HR 8799's planets.

  Explanation/Reference:

  Despite overall physiological bilateral symmetry, many species exhibit lateralized biases, i.e., preferences for right- or left-oriented behavior. When approaching prey, for example, some predator species favor their right eye; some prey species respond more quickly when their left eye detects a predator. Similar behavioral asymmetries occur in humans. Most notable is right- and lefthandedness; less notable is the tendency to turn right when entering a room. Paul Farnsworth found that more successful students tended to choose seats near the front, a little to the right. He arqued that external factors such as teacher location might have affected this lateral bias. But it is now known that processing differences between the two brain hemispheres can also contribute to behavioral asymmetries. George Karev found that when presented with a movie theater seating diagram, right-handed people were more likely than left-handed people to choose a seat on the right, facing front. But he hypothesized that, since the right hemisphere processes visuospatial and emotional information, the people who chose right- side seats did so because that would put the screen in their left visual field, optimizing information flow to the right hemisphere. Although the right hemisphere is thought to be dominant in processing emotion, some evidence suggests that the left hemisphere plays a role. The valence model proposes that the left and right hemispheres process positive and negative emotion respectively, while the approach-withdrawal model posits that the left hemisphere processes emotion expressed in approach behavior and the right hemisphere processes emotion expressed in withdrawal behavior. Victoria Harms and colleagues suggested that since a paper seating plan was used in the theater-seating studies by Karev and others, the exhibited preference might be due simply to handedness: people choose the same side of the paper as their favored hand. Consequently, the Harms research was designed to study choices in an actual movie theater. Also, hoping to distinguish between various explanations, they studied seating choices for comedies (presumed to contain positive emotional content), dramas (presumed to contain negative emotional content), and documentaries (presumed to have balanced emotional content). They found significant--though not universal-- preference for seats on the right, facing front, regardless of movie genre and of handedness.

• Question 257:

  Despite the fact that the seeds of certain tropical trees fall mostly around the parent tree, the seeds that land farther from the parent trees of these species have the greatest chance of germinating. One hypothesis is that the effect is caused by rodents eating a larger number of seeds beside the parent tree than seeds in places farther away, but studies have shown that this is not so.

  Which of the following, If true, would most help explain the effect described above?

  A. Tree sprouts from seeds must compete for moisture and nutrients with some of the plant life in their immediate vicinity.
  B. Some tropical trees have winged seeds that tend to prevent them landing beside the parent trees.
  C. Certain tropical tree species are preferentially colonized by some types of mammals.
  D. Soil microbes that prey on seeds and other biological material from trees of the tropical species in question tend to be densest near those trees.
  E. Some plants emit chemicals that are harmful to nearby seeds of other species.
  D. Soil microbes that prey on seeds and other biological material from trees of the tropical species in question tend to be densest near those trees.

• Question 258:

  The passage most strongly indicates that the author would agree with which of the following statements?

  A. None of the subjects in the various studies other than the 1998 study who seemed to commit the conjunction fallacy actually did commit it.
  B. People who have studied the mathematical principles of probability are very unlikely to commit the conjunction fallacy.
  C. The conjunction fallacy is rarely committed outside of betting contexts.
  D. Many of the subjects in the various studies In addition to the 1998 study probably committed the conjunction fallacy.
  E. The conceptions of "probability" that underlie everyday use of the word rarely, if ever, conform to the mathematical principles of probability.
  E. The conceptions of "probability" that underlie everyday use of the word rarely, if ever, conform to the mathematical principles of probability.

  Explanation/Reference:

  Mathematical principles of probability entail that for any future event, the probability that it will occur Is at least as great as the probability that both it and some other given event will occur. Consider, for example, the following statements that were shown to subjects in a 1998 study. X The percentage of adolescent smokers In Texas will decrease at least 15% from current levels by September 1, 1999. Y The cigarette tax in Texas will increase by $1.00 per pack in 1999. Z The cigarette tax in Texas will increase by $1.00 per pack in 1999, and the percentage of adolescent smokers in Texas will decrease at least 15% from current levels by September 1, 1999. Z("Kand X") could not have been more probable than X. Nevertheless, many of the subjects judged Zto be more probable than X. This mistaken form of reasoning, displayed with surprising frequency in various studies in addition to the 1998 study, is known as the "conjunction fallacy." A number of researchers have offered alternative explanations for the seeming manifestations of the mistake, thus arguing that the fallacy is less widely committed than the various studies would indicate. Some have claimed that research subjects can take "probability" in a sense that does not conform to the mathematical principles of probability. Detailed descriptions of some such conceptions of "probability" have been developed under the names of "confirmation" and "support." Other researchers would claim, correctly, that subjects shown Z(" Kand X") and ^simultaneously will sometimes think of Xas involving the negation of Y--as a claim that the percentage of adolescent smokers in Texas will decrease, but without the $1.00 increase in the cigarette tax. However, although the subjects in the 1998 study were to consider Xand Z simultaneously, the statements were presented in terms of bets rather than explicit requests for judgments of relative probability. Subjects were asked to choose between Zand X, with a chance of winning $50.00 if the chosen statement turned out to be true. Terms such as "most probable," "likely," etc., were thus avoided, and the interpretation of X\n conjunction with the negation of Kwas thereby eliminated. And with these alternative explanations eliminated, many of the subjects nonetheless bet on Zrather than
