  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 argued 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 chaices 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.

  ---

  Explanation/Reference:

  The following is based on an article published in 2012. Most linguists believe proto-Indo- European, the ancestor of all Indo-European languages, was the language of chariot-driving pastoralists who spread through Eurasia from steppes north of the Black Sea about 4,000 years ago. But a competing theory is that proto-Indo-European was spoken by farmers in Anatolia (Asia Minor) about 9,000 years ago, and spread from there along with agriculture. To evaluate these hypotheses, researchers statistically compared IndoEuropean languages' vocabularies. Languages with more similar vocabularies are probably more closely related, sharing more recent common ancestors. Combining the vocabulary statistics with the known dates when certain languages split, and with their known geographical ranges, a computer calculated the most likely relationships among all Indo-European languages and concluded that protoIndo- European probably originated in Anatolia 9,000 years ago. Disputing this conclusion, skeptics argue that most Indo-European languages are similar in their words pertaining to chariots and wagons, suggesting protoIndo- European split into daughter languages only after chariots and wagons were invented. No archaeological evidence indicates that chariots and wagons existed before 5,500 years ago. Furthermore, proto-Indo-European had words for "horse" and "bee" and lent many words to proto-Uralic, the mother language of Finnish and Hungarian. The steppes north of the Black Sea were far closer than Anatolia to areas where proto-Uralic was spoken, and had more abundant wild horses and bees.

  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

  X:

• Question 420:

  HOTSPOT

  The Red Balloon Challenge was an experiment aimed at determining how quickly widely disbursed information could be gathered using social media. Competitors tried to locate 10 red weather balloons that had been tethered above random locations around the world in return for a $40,000 prize. The winning team located all of the balloons in just 9 hours, using an incentive-based strategy to encourage information sharing; The first person to send the correct coordinates of a particular balloon to the team received $2,000, but whoever recruited that person received $1,000, and the recruiter's recruiter received S500, and that person's recruiter received $250. Select for 3 payments per balloon the amount of the prize money that the winning team would have remaining if they had to pay 3 people for each balloon located, and select for 4 payments per balloon the amount of the prize money that the winning team would have remaining if they had to pay 4 people for each balloon located. Make only two selections, one in each column.
