Motivation
An inferred process within a person or animal that causes movement either toward a goal or away from an unpleasant situation. Can come from biological drives and more.
Drives
biological urges, such as those to acquire food & water, to have sex, to seek novelty, and to avoid cold and pain
Intrinsic motivation
the pursuit of an activity for its own sake and the pleasure it brings
Extrinsic motivation
the pursuit of an activity for external rewards, such as money or fame
The Biology of Weight
- Research does NOT support the idea that people who are overweight are emotionally disturbed
- Heaviness not always caused by overeating
- Biological mechanisms regulate your body weight & are influenced by genetics
Set point
-Genetically influenced weight range for an individual (maintained by biological mechanisms that regulate food intake, fat reserves, and metabolism)
Varies about 10% in either direction
-Associated with high levels of heritability
-Related to genetically programmed basal metabolism rate
Genetic Obesity
Mutations in the ob gene may cause obesity in some individuals
Ob Gene
- Causes fat cells to secure protein called leptin that acts on the hypothalamus and helps to regulate appetite
- Levels of leptin most critical in early life as sets the brain chemistry involved with eating
Prevalence of obesity in Canada
Approximately 26% of women & 35% of men
Has been increasing over the years
Can’t be accounted for solely by genetics
Is it weight or fitness?
Many researchers believe that individuals who are overweight and physically fit are actually healthier than individuals who are sedentary and thin
Lack of fitness related to greater health risks
Environmental Influences on Weight (5)
- Increased abundance of fast food
- Consumption of high-calorie soft drinks
- Decline of exercise and other expenditures of energy
- Increased portion sizes of food and drink
- Abundance of highly varied foods
Culture of Consumption
Eating habits & activity levels shaped by customs and standards of ideal body
- Fat may be sign of health & affluence in men; sexual desirability in women
- English Canadians hold negative attitudes towards obese people
Culture & the Ideal Body (4)
- Cultural ideals for women have been getting thinner, with large breasts but no hips
- Cultural ideals for men are to have strong, muscular bodies
- Changes in body norms shift with gender and social roles (e.g., woman’s role being home or work?)
- Differences in weight satisfaction between men & women influence weight norm
Anorexia
An eating disorder characterized by fear of being fat, a distorted body image, radically reduced consumption of food, and emaciation
Bulimia
An eating disorder characterized by episodes of excessive eating (bingeing) followed by forced vomiting or use of laxatives (purging)
Types of Love (2)
Passionate (romantic) and Companionate
Passionate (romantic) love
Love characterized by a whirlwind of intense emotions and sexual passion
It is the stuff of crushes, infatuations, “love at first sight”, and the early stage of love affairs
Companionate love
Love characterized by affection and trust
Endorphins
Chemical substances in the nervous system that are similar in structure and action to opiates; they are involved in pain reduction, pleasure, and memory and are known technically as endogenous opioid peptides.
Proximity effect
the people who are nearest to you geographically are most likely to be dearest to you too (long distance relationships worse outlook on relationship)
Similarity effect
similarity in looks, attitudes, beliefs, values, personality, and interests, is attractive to human beings
Attachment theory of love involves 3 types. What are they?
secure, avoidant, and anxious
Secure
rarely jealous, compassionate, helpful (64%)
Avoidant
distrust others and avoid intimate attachments (25%)
Anxious
agitated in relationships, clingy, fear partners will leave them (11%)
Men and women do differ in how they express love
Males more likely to express love in actions
Women more likely to express love in words
Motives for sex
Human sexuality influenced by biological, psychological, and cultural factors.
Canadian sex statistics
- Canadian culture relatively sexually active
- Canadians have sex at earlier ages than teens in other countries
- Average Canadian adult has sex around 150 times a year
Testosterone
promotes sexual desire in both sexes, but relationship unclear
