Textbook Question
Chapter 26.4, Problem 1CSC
Does symmetry have a scent? In one study, researchers measured the body symmetry of 80 men and then issued a clean T-shirt to each one. Each subject wore his shirt to bed for two consecutive nights. A panel of 82 women sniffed the shirts and rated their scents for “pleasantness” and “sexiness.” Which shirts had the sexiest, most pleasant scents? The ones worn by the most symmetrical men. The researchers concluded that women can identify symmetrical men by their scent.
What other kinds of messages do animals send with pheromones and other signals? Find out just ahead, in Section 26.5.

Can parents distinguish their own children by smell alone?
To investigate, Porter and Moore (1981) gave new T-shirts to children of nine mothers. Each child wore his or her shirt to bed for three consecutive nights. During the day, the shirts were kept in individually sealed plastic bags. No scented soaps or perfumes were used during the study.
Each mother was given the shirt of her child and one shirt of another randomly chosen child. She was then asked to identify her own child’s shirt by smell. Eight of nine mothers identified their children correctly.
Answer the following questions using a two-sided test and a significance level of 0.05.
Distinguish between static and dynamic equilibrium. The sense of equilibrium (balance) is really two senses— static equilibrium and dynamic equilibrium—that come from different sensory organs. The organs of static equilibrium (stat′ik e″kwı˘-lib′re-um) sense the position of the head, maintaining balance, stability and posture when the head and body are still. When the head and body suddenly move or rotate, the organs of dynamic equilibrium (di-nam′ik e″kwı˘- lib′re-um) detect such motion and aid in maintaining balance.
The Siamese cat pictured is called a “seal point” because it has seal-colored (dark brown) extremities. Some Siamese cats show the same color pattern, but the dark areas are of a lighter color or even a different shade—for example, lilac point, red point, blue point. What results would you predict if the experiments described in the text (shaving the cat and then increasing or decreasing temperature) were conducted on cats with these color patterns?

- Think about the color purple. I’m sure you are imagining a variety of shades of the color of royalty from a deep violet to a subtle lavender and everything in between. But while it seems to be a fairly straightforward concept, describing a color is a much more daunting task. First, we need to understand what color is and how people perceive color. To further confound matters, color vision from one person to another is not set in stone; the variety and combination of the cells in the back of your eyes will determine the colors you see, and the way you’ve experienced the world will teach you how to describe them to others. What started out as a concept that most children learn before they set foot in a schoolroom has quickly morphed into an immensely complex set of issues. To help address some of the complexity of sight and color perception, we will approach it from a cellular level to understand how light can be transduced into a nervous signal.

The mallet was used to display an accurate time of impact compared to reaction time. The visual reaction to stimulus had a shorter average reaction time than the visual reaction to light. This occurred in both the dominant and non-dominant eyes. Even though the reaction times were faster on average, the dominant eye was still slower to react.

They hire a group of physical trainers and a statistician, who recruits 100 healthy adult runners with the same age range to participate in a study. The statistician randomly assigns the 60 runners to follow the se weekly running schedule, wherein 30 runners will use new insoles and the remaining 30 will use the existing insoles the company already sells. After 10 weeks, the statistician records the number of runners from each group that has developed shin splints. They made sure that the results are valid that they have performed the testing three times for each treatment. Illustrate the type of research design used in the situation.
