24. Contrast the two decision-making strategies of "maximizing" vs. "satisficing" (perhaps, use the examples of buying new running/athletic shoes, or selecting cookies at the grocery store).

"Sacrifice" more and "Maximize" less: Rapid choice, Sacrifice ex. I want some shoes that I use for walking, I want it to be light, I'm a student and only have 60$ (big criteria), ex. Maximize bring me all the size 11 shoes In the end, they are more likely to make better objective choices than satisficers but get less satisfaction from them. When reality requires maximizers to compromise— to end a search and decide on something—apprehension about what might have been takes over We found as well that the greatest maximizers are the least happy with the fruits of their efforts. When they compare themselves with others, they get little pleasure from finding out that they did better and substantial dissatisfaction from finding out that they did worse. They are more prone to experiencing regret after a purchase, and if their acquisition disappoints them, their sense of well-being takes longer to recover. They also tend to brood or ruminate more than satisficers do. Working with Columbia University psychologists Rachael F. Elwork and Sheena S. Iyengar, I found that maximizing college seniors searching for jobs actually found positions with 20 percent higher starting salaries than satisficing job seekers. Yet the maximizers were less satisfied with the jobs they got, and with the entire search process, than the satisficers were.

A

Stress

A psychological and physical response of the body that occurs whenever we must adapt to changing conditions, whether those conditions be real or perceived, positive or negative. Although everyone has stress in their lives, people respond to stress in different ways. Some people seem to be severely affected while others seem calm, cool, and collected all the time. Regardless, we all have it. It's also important to note that there are two types of stress, Eustress (good stress) and Distress (not so good stress). -Your heart pounds faster, muscles tighten, blood pressure rises, breath quickens, and your senses become sharper. These physical changes increase your strength and stamina, speed your reaction time, and enhance your focus—preparing you to either fight or flee from the danger at hand.

23. In the 1950's, Psychologist Eric Ericksen followed up Freud's observation by pointing out that, at the beginning of adulthood, it would be natural to explore the range and boundaries of one's interests in work and love. A great example is that many young people between ages 20-30 will work in a variety of jobs and internships, exploring their eventual career interests. Give examples, from lecture or your life, of potentially fatal explorations in the areas of work and love.

24. Attribution (What "causes" your grade in EXB 10? Give examples of internal vs. external attribution. Can you see how these different explanations might influence your preparatory behavior for our final exam?)

In an internal, or dispositional, attribution, people infer that an event or a person's behavior is due to personal factors such as traits, abilities, or feelings. In an external, or situational, attribution, people infer that a person's behavior is due to situational factors. Example: Maria's car breaks down on the freeway. If she believes the breakdown happened because of her ignorance about cars, she is making an internal attribution. If she believes that the breakdown happened because her car is old, she is making an external attribution. Ex. I might not get an A in this class because everyone around me is talking and distracting me from studying. I might not get an A because I have no motivation to study

Things that make us happy are not things individuals with high maximization scores experienced less satisfaction with life and were less happy, less optimistic and more depressed than people with low maximization scores. Indeed, those with extreme maximization ratings had depression scores that placed them in the borderline clinical range.

20. In terms of calorie balance, what is the necessary prerequisite for loss of body fat stores, and how does this differ from what is necessary to maintain body fat and weight?

To lower your body fat you need to have a lower calorie intake than the calories you are burning through exercise, but to maintain fat and weight you need to exercise and keep your calorie intake at a balance Exercise (during a caloric restriction) Preserves Lean Mass and Focuses Weight loss onto Fat. Exercise Stabilizes Lean Mass and Body Composition "Create a Caloric Deficit to Lose Body Fat; Exercise to Maintain Body Fat"
