| Paper Airplane Producers: Morning Types vs. Evening Types Posted: 26 Jul 2011 05:05 AM PDT
by David L. Dickinson, Dept. of Economics, Appalachian State University, and Todd McElroy, Dept. of Psychology, Appalachian State University People differ in their diurnal (time of day) preferences: some are morning-types and others are evening-types. These differences are explored in a unique experiment design in which subjects are randomly assigned to produce paper airplanes at either 8:00 a.m. or 10:00 p.m. Our results show that evening-types, at their optimal time of day (10:00 p.m.), produce planes that fly statistically significantly further than those produced by morning-types at their optimal time of day (8:00 a.m.). Evidence also indicates that planes produced by evening-types fly straighter. Background Paper airplane flight distance is a commonly considered outcome measure in the world of paper airplanes, though not the only one: other measures include time aloft, flight stability, and aerobatics. Our experiments examined how one's diurnal preferences (i.e., morning-types versus evening-types) affected the flight distance and accuracy of the airplane they constructed. Modern society often requires performance at non-preferred times-of-day (e.g., evening- types in the early morning), and some limited research has shown that such "circadian mismatch" affects decision- making (Bodenhausen, 1990; Kruglanski and Pierro, 2008; Dickinson and McElroy, 2009).3 Thus, we hypothesize that circadian mismatch may deplete cognitive resources and harm important paper airplane outcome measures. Figure 1: Data generation diagram. Sample flight. NOTE: Airplane shown in figure is classic "dart" design. Lightning bolts are for illustrative purposes only, and were never witnessed during our research flights. The Experiments Figure 2: Cumulative distribution functions vs. paper airplane flight distances. Flight distances (in inches) do not significantly differ for the unconditional match vs. mismatch comparison. However, conditional on being circadian "matched", EM subjects' mean flight distance was 36% greater than that of the MM subjects' airplanes (p=.03). The cumulative distribution functions of flight distance are shown in Figure 2 (circadian matched subjects in bold lines), and we see that almost 40% of evening-type subjects Results: Flight Trajectory However, evening-type subjects made airplanes that flew significantly straighter than the average plane made by a morning-type person (p=.03). This was especially so when people made planes at what was, for them, circadian mismatched times. Table 1. Summary data. Note: Flight Distance and OffCenter are given in inches Discussion The most significant determinant of paper airplane outcome measures in our experiments was one's diurnal preference. Evening-types seem to be the wise choice for these tasks, no matter the time of day. As an example of the implication of this result, consider that EMM planes diverged at 12° from departure.6 Now consider a flight from New York's JFK airport to the Seattle–Tacoma airport (2405 miles flight distance). At 12° divergence, assuming a linear flight path, the plane would be approximately 500 miles from Seattle when reaching the West Coast (near Chico, CA, for example). All else equal, had that plane been designed by an MMM engineer, diverging 18.7° from departure, it would end up about 800 miles from Seattle (between Fresno and Bakerfield, CA.). Modest assumptions about the time and resource costs per passenger to correct that 300-mile difference, multiplied by over 40 weekly flights from JFK to Seattle, show how quickly the impact of this effect could add up.7 Policy prescriptions for the airline industry are straightforward. Job recruitment practices could be modified to discriminate against morning-types, as our results indicate that evening-type workers should produce better aircraft. If airline production schedules are also altered to disproportionately utilize evening shifts, the industry would further benefit from improved aerodynamics design of the type that led to increased paper airplane flight distances in our study. While the prevailing wisdom is that "the early bird gets the worm," this research argues that night owls are getting the worms in this particular paper airplane task. Future research might consider expansion of the outcome measure (e.g., aerobatics, flight stability), and the study of sleep personality effects on broader classes of engineering or manufacturing outcomes.

Notes 2 Yamaguchi (2008) reports that a prototype has already successfully passed a wind tunnel durability test. 3 Without examining circadian mismatch per se, sleep researchers have documented decreased performance in a variety of arenas at adverse circadian phase times (e.g., Wright et al, 2002; Horowitz et al., 2003; Bjerner et al, 1955) 4 Paper airplane flight objectives include not only distance traveled, but also flight time, and acrobatics. We only explore the first in this paper. 5 We count the final resting point in calculating our total flight distance, while others may choose to count distance to where the plane hits ground. Because planes that fly straighter are more likely to have a longer landing slide, our data probably contain a positive bias on flight distance for straighter flights. 6 Our calculations of degrees off at departure likely underestimate the true degree of divergence, because our estimates assume linear divergence. Our recollection is that many paper airplane flights that were off-center followed a nonlinear divergence path (i.e., a convex flight path that was diverging at an increasing rate) 7 If you are thinking that pilots themselves could correct flight paths, perhaps with the help of air traffic controllers, then you perhaps forget that the culture in both those professions gives rise to sleep deprivation (see Coren, 1996).

| What Playing In The NFL Does To Your Brain Posted: 26 Jul 2011 01:14 AM PDT Football is definitely back this fall, but will the players show up after seeing this insightful video about what playing in the NFL does to your brain? Former player Dave Duerson donated his brain to the NFL Brain Bank so researchers can clearly see what happens when you knock your head around for a living, and the results aren’t very pretty. But did anyone really think being a professional football player would be good for your mental health? I think not. |

| The Battle of Opossums Vs. Snakes Posted: 26 Jul 2011 12:19 AM PDT In the eternal struggle for survival, animals are constantly evolving new strategies to win. This arms race is particularly evident when looking at the fight between opossums and snakes. Possums have built up a tolerance to pit viper venom by eating the potential predators. This has also helped them protect themselves from bites from rattlesnakes and copperheads. Even more interestingly though, the viper is constantly evolving more deadly poison:

| New Birth Control Pill... for Dogs Posted: 25 Jul 2011 02:57 PM PDT Both the ASPCA and Humane Society strongly encourage pet owners to spay and neuter their furry friends to prevent overpopulation (and a dearth of homeless puppies, sad face). It shouldn’t really be a surprise, then, that there is a less invasive option in the works. But let’s face it, it’s kind of a crazy idea, right? Not so, according to a group of scientists in Arizona.

| Magnetic and Electric Properties in a Single Material Posted: 25 Jul 2011 09:17 AM PDT Scientists at the U.S. Department of Energy's Brookhaven National Laboratory announced today that they have observed a rare property in a special class of metals called multiferroics: they have both magnetic and electric properties, which normally don’t happen in the same material. Ferromagnets are, of course, magnetic metals, and ferroelectrics are materials that have a permanent electric polarization.
