Define intelligence
Intelligence is the ability to learn from experience, solve problems, and use knowledge to adapt to new situations
What is reification?
Reification is the cognitive error of making something real when it is not
•very common among western countries with intelligence.,/
What is spearman’s g factor?
- general intelligence
* intelligence factor that underlies specific mental abilities and is measured by every task on an intelligence test
What is factor analysis?
Factor analysis was founded by spearman.
-1,0,+1 strength of correlation
Data reduction technique
Savant syndrome + implications for intelligence
A condition where someone who may lack mental ability due to disability may excel in a particular area: ex. Computation or drawing
Multiple Intelligences. What’s the theory?
Gardner believe we did not have 1 single intelligence, but rather multiple intelligences. Ex. An artsy kid and a basketball player exhibit different kinds of intelligence
Francis Galton
Cousin of Charles Darwin
- wondered if ones natural ability could be measured
- tested adults in London and no correlation was found (failed)
- gave the phrase nurture v nature
Binet + Simon
Studied children and France. Wanted to find a mental age.
Kids who performed average, above average, and below average
Never questioned why some kids have certain mental ages
Aptitude tests
Tests on how well you will do in the future. Closely related to standardized testing. Ability to learn a new skill
Standardized Tests
Closely related to aptitude tests. Tests how well you will do in college
Achievement Tests
Tests based on what ones already learned
Identical Twin study
Monozygotic twins were found to have high heritability concordance. (Similar iqs)
•their iqs are not exactly the same because of environmental factors
Heritability of intelligence
The extent to which intelligence test score variation can be attributed to genetic variation (50-80%)
The environmental influence of neglect on intelligence
Poor environmental conditions can depress cognitive development. Malnutrition also plays a role.
Children that may have had high potential were depressed by being deprived

Define motivation
A need or desire that energizes and directs behavior
4 perspectives to explain motivation
- instinct theory: genetically predisposed behaviors
- Drive reduction theory: how our inner pushed and external pulls interact
- Arousal theory: finding the right leek of stimulation
- Maslows hierarchy of needs
Define instinct

Maslows Hierachy of Needs
- Self transcendence needs
- self actualization needs
- esteem needs
- Belongingness and love needs
- Safety needs
- physiological needs (hunger, thirst)
Ancel Keys’ study
Studies semi starvation by cutting off the food supply of 36 make volunteers (by 1/2)
Without thinking their bodies began conserving energy; appeared listless and apathetic
Body weights stopped dropping at about 25% ⬇️ starting weights
Physiologic basis of hunger
Major structure:
Hypothalamus
•lateral hypothalamus
-if stimulated, you eat. If destroyed you starve
•ventrahedial hypothalamus
- suppresses hunger
-if destroyed you will eat yourself to death
The role of hypothalamus and appetite hormones
Orexin: hormone that makes us hungry
Ghrelin: hormone that stimulates hunger in an empty stomach
Obestatin: hormone that sends out full signals
