Chapter 13 Motivation and Emotion February 4
Motivation is the energy that makes people do something, also giving direction
There are three characteristics of motivation:
1) Initiation of our actions
2) Determines what we pursue
3) Determines how intensity and persistently we pursue it
Drive Theory of Motivation
Humans have basic biological needs that are essential for survival: food, water, air, sleep,
When deprived of a need (food, water, air, warmth…etc), there is motivation for people
to get it, people are motivated (driven) to meet the needs
There is a regulatory system (cyclical, loop system) to achieve a steady state regarding
the need (i.e. Homeostatic system)
There are three properties of a homeostatic system (using thermostat example):
1) There is a set point (desired temperature)
2) There is a device for detecting deviations from the set point
3) There is a corrective mechanism (during winter, furnace comes on to adjust
temperature to set point)
Homeostasis in Hunger
The set point (satiation)
Detecting deviation (nutrient detectors in the human body signal depletion)
There is a corrective mechanism (hunger and drive to eat)
There is more than homeostasis in the motivation to eating then justreaching the set
Some factors are social pressure:
Social pressure (eating alongside friend)
Hedonism (greed to seek pleasure such as good taste)
Cultural norms (different expectations, respect for food)
Video on the Way We Eat
Food is more than just the nutrition
Diabetes occurring more frequently in people (even children)
Even though people know better, people are compelled to eat food because food is
attractive, good taste
Lower income groups are more affected by obesity because they look for cheaper, larger
portions foods
Culture and Diet
Different cultures have different diets (diversity in ingredients, the way the ingredients
are prepared)
