Chapter 4
I-Introduction

- Is it nature or nurture that defines us?
o Nature – genes, heredity
o Nurture – everything else that is not genetic (experience, environment) - Both are equally important in shaping who we are. There is also an interaction between the two.

STUDY NOTES ONLY

II – The Nature Component

A) Genes:

- 46 chromosomes, 23 pairs.
- Genes carry DNA, which consists of thousands of genes amongst other things. - Genes = Basic Unit of Heredity
- Gene complexes are genes working together to produce a trait or disease. - 4 Nucleotides:
o Adenine (A)
o Thymine (T)
o Guanine (G)
o Cytosine (C)
- The sequence of nucleotides determines what a specific gene does or does not do. o Chromosomes = Books
o Genes = Words
o Nucleotides = Letters
- People are 99.99% similar to each other
- Repartition of the 0.01% difference:
o 5% differences among “races”
o 95% differences within a “race”

- Us compared to:
o Monkey: 95-98% similar
o Mouse: 80%
o Banana: 50%
o Fruit Fly: 44%
o Daisy: 30%

NOTES ONLY

B) Evolutionary Psychology (EP)

- What is EP?
o It is the newest perspective in psychology. Heavily influenced by Darwin and his Theory of Evolution. The main goal for an organism is to survive and transmit genes to the future. Natural Selection (Only the fittest will survive) o Our capacity to adapt is what makes us so strong.

Clark & Hatfield s
- Sent male and female average looking assistants out into public. When they see someone that is attractive, they asked them if they want to go to bed with them. Almost 100% of women said no, and a lot of men said yes.

Why?
- According to EP, men and women have the same goal but different strategies. Women would prefer to have a partner to ensure survival of the baby. Therefore they don’t prefer to have recreational sex.

EARN A POINT
If women are not into recreational sex, whom are the men sleeping with?

18 societies that we know of, women are encouraged to have multiple partners.

NOTES + EARN A POINT

C) Behavior Genetics

C.1. Introduction

- Interaction between nature and nurture, people are interested in understanding individual differences.

C.2Twin Studies:
- Two types of twins: monozygotic twins and dizygotic twins
- Monozygotic:
o 1 egg, 1 sperm, same sex, 100% genetically similar
- Dizygotic:
o 2 eggs, 2 sperm, 2 embryos, same or opposite sex, 50% genetically similar

- Rationale:
o If a behavior has a genetic component, then an identical twin should be more similar compared to fraternal.

- If 1 is diagnosed with Alzheimer’s disease, then the other twin has a 60% chance of being diagnosed with the disease. - Fraternal twins are 30% for Alzheimer’s

- Twin studies were criticized; identical twins share the womb, school…etc. They have the same environment.

- The solution was to study twins reared apart, run by Bouchard

- This was eve criticized saying that even random strangers will have similarities if you go through enough stuff.

- Solution:

- Study Identical Twins similarities and compare it to Strangers similarities

- CONCLUSION:
o Even though I.D. twins reared apart are less similar than I.D. twins reared together, they are still more similar to each other than fraternal twins reared apart

C.3 Adoption Studies

- Rationale:
o An adopted child has two sets of parents:
• Share genes with biological parents
• Share environment with adoptive parents

- Results:
o Even though adoptive children don’t share the environment with the biological parents, their personality is more similar than the adoptive parents.

C.4 Family Studies

- Rationale:
o Family members are more genetically similar than strangers

- Regular siblings: 50% genetically similar
- Parents: 50% genetically similar
- Grandparents: 25% genetically similar
- Cousins: 12.5% genetically similar

- If a behavior has a genetic component, then people who are genetically similar should be more similar than strangers. NOTES ONLY FOR ABOVE

C.5 Temperament Studies

- Definition:
o Temperament studies is the typical way to emotionally respond to life

*Seems to be a genetic component (from birth there are differences in temperament)

- Easy Babies: (40%)
- Slow-to-warm babies (15%)
- Difficult babies: (10%)
- Combination: (35%)

- Physiological Studies:
o Difficult Babies – higher heart rate, etc. …therefore a genetic component

- Nurture is very important in affecting temperament
- American babies are more positive than Asian and Russian Babies

C.6 Heritability

- Definition:
o The extent to which differences between individuals are due to genetics

- h2=heritability coefficient

- h2= Variancegenes/ (Variancegenes + Varianceenvironment)

- h2 varies from 0 to 1

o h2 = 0.0 → no genetic influence

o h2 = 1.0 → all variance is due to genetics

o h2 = 0.4 → 40% genes, 60% environment

- When environment is similar, h2 will be high
- When environment is different, h2 will be low

- Just because individual differences are heritable, it does NOT mean that differences between races, gender, generations are heritable.

C.7 Nature and Nurture Interaction

- Genes may need the environment to turn them on
- Environment can turn off genes that are active
- Ex. Rats have to smell, see and hear their baby rat to nurture them.

D) Molecular Genetics

- Study DNA
- Pros:
o Can follow genes and prevent diseases, cancer, etc.
- Cons:
o If a gene is identified, people may abort babies, pilots are refused due to health problems, etc.

III. The Nurture Component

A. Prenatal Development

- Nurture begins at the moment of conception
- From conception to birth
- Safety of the womb is not 100%
- Even though twins share the womb, they don’t necessarily share the same environment

B. Experience and Brain Development

B1. Experience Facilitates Brain Development
- No matter what potential you are born with, it won’t reach its full potential without experience - Without stimulation from the surroundings, the brain will not develop properly

B2. Experience Changes the Brain

- The human brain will change with experience
- Study:
o Rats with more resources (toys, bigger cage, etc.) had thicker heavier brain and more neuron connections - High school drop out vs. University Student
o 40% more neurons

C. How Much Credit or Blame Do Parents Deserve?

D. Peer Influence

- Peer: people of the same age or maturity level
- Importance of peers:
o Can be traced as far back as infancy
o How babies act towards other babies is a strong indicator of later life o Children with no peers create invisible friends
o Children rejected/bullied by peers, they suffer mentally
- Growing interaction = growing influence
o Risk taking behaviours heavily influenced by peers
• Selection effect:
• If you re interested in smoking, for example, you will move towards peers that smoke

- Parents can influence children in 3 different ways:
o They choose where to live, what school, etc.
o Parent-child interaction influences peer-child interaction o Advice on how to handle peer relationships

E. Culture

- Study on your own.

IV. The Nature and Nurture of Gender
- Gender similarities and differences ******* FINAL EXAM

- The sex chromosome
o XY
• Mom contributes only to the X
• Dad contributes to either the X or Y
• XX=female, XY=male

- The first few weeks of life in the womb
o Not differences between male or female
o Gene on the Y chromosome called SRY about the 7th week, which creates testes o Hormones influence brhaviour and identity
o Women (if lots of testosterone) will have more masculine behaviours (interests in women, genitalia more masculine) o Men (cells don’t respond to testosterone)

III. The Nature and Nurture of Gender

- The role of culture and society
- Gender Identity:
o Strong psychological sense of maleness or femaleness
- Gender Roles
o Varies from one culture to another, as well as varying over time - Gender Type:
o Adoption of traditional role by a man, or adoption of traditional role by a female

- Learning about Gender
o Social learning theory
o Gender schema theory
• Do not accept that we learn through observation, etc. Don’t think the SLT goes far enough. Children taking in and organizing information. Ex. Boys don’t play with dolls, therefore I shouldn’t play with dolls

Chapter 5: Human Development

I. Introduction
- Developmental psychology
o Studies how we change/develop across the lifespan
- Patterns of change from the moment of conception to the moment of death - The 4 major issues of developmental psychology:
o Nature/Nurture
o Nature of Development (Is development continuous or occurs in stages) o Stability vs Change (Traits)
o The Impact of Early Experience

II. Prenatal Development and the Newborn

A. Conception

- 200 million sperm
- Releasing enzyme to break the protective layer and 1 sperm is taken in - Once the sperm is taken in, the protective layer is reformed - 1 out of 5000 eggs will mature
- Fewer than half of the fertilized eggs will survive past 2 weeks

B. Prenatal Development

B1. Three Stages of Prenatal Development

- The germinal Stage
o First two weeks
o Refer to the baby as a zygote
o When the baby is born, the zygote would have split into trillions of cells o Travels from the fallopian tube to the uterus
o Zygtoe attaches to the wall of the uterus
- Embryonic Stage
o 3rd week to the 8th week
o Placenta will form
o Nervous system is formed
o Heart will begin to beat
o Limbs begin to form
- Fetal Period
o Week 9 to the birth of the baby

- Cognition
o A higher order mental process used to understand and adapt to the world

- Jean Piaget
o Most influential psychologist in the 20th century
o NOT a psychologist, but a biologist
o Studied for 50 yeas
o Children are not little people, the mind is different than that of an adult o Children are not “soaking things in”, they are active learners • Assimilation: new experience fits into existing schema

• Accomidation: the child will change the existing schema to fit in the new experience

- Accomidation occurs in 4 stages
o Sensorimotor Stage (0-2yrs)
• Uses senses and motor ability in order to acquire knowledge • Major achievement: Object permanence
o Preoperational Stage (2-7yrs)
• Animism, egocentrism, literal thinking, symbolism
• Major limitations:
• Unable to perform mental operations
• Concentration (focus on 1 aspect and disregard all other aspects) • Conservation (an object remains the same, even though some of the superficial properties have changed) o Concrete Operational Stage (7-12 yrs)

• Can perform concrete mental operations
• Concentration and conservation are not a problem
o Formal Operational Stage (12 yrs and up)
• Abstract, theoretical thinking

Between 50 and 60 questions
Chapters 4,5, and 10
Chapter 10 – Intelligence

1. What is Intelligence?

A) Definition: hundreds of definitions for intelligence. Thinking rationally and solving problems is linked to intelligence.

B) One or Several Intelligences?

NOTES

B.1 The Factor Analysis Approach

- psychometric approach
- Factor Analysis is a very powerful statistic procedure
- Statistical procedure used in order to identify common factors among clusters of test items

- Spearman → cofounder of factor analysis
o A specific intelligence is defined as “g” (general intelligence o “s” (specific abilities)
NOTES

B.2 Contemporary Approach

Gardner: Multiple Intelligence:

- Logic:
o Neurologically separate
• If someone has an accident and has brain damage, they lose some abilities but not all. ← Great indicator that we have multiple intelligences according to him. - Savants:
o Super brilliant in one or more areas, but in the same time they have way below average intelligence in other ways - Prodigies:
o Super brilliant in somethings, but average in others
- Different abilities develop among different courses

- The intelligences:
o Linguistic (smart with words)
o Logical-mathematical
o Musical
o Bodily-Kinesthetic
o Spatial
o Interpersonal
o Intrapersonal
o Naturalist (understand environement)
o Existential
NOTES

Sternberg’s Approach:

- Analytical Intelligence (book smart)
- Creative Intelligence (thinking outside the box)
- Practical Intelligence (solving everyday life problems)

NOTES

3. Emotional Intelligence (EQ)

- Mayer, Salovey & Caruso (coined the term EQ)
o People who have a high IQ are not the most successful in life • Knowing your emotions
• Understanding emotions
• Managing your feelings
• Self-motivation
• Delay of gratification
• Recognizing other’s emotions
• Managing other’s emotions
NOTES AND BOOK

II. Assessing Intelligence

A. Origins of Intelligence Testing
B. Modern Tests

^^^^^^^^^^EARN A POINT^^^^^^^^^^^

C. Principles of Test Construction

- Standardization
o Large group representative of the population you are interested in o Use the scores of the specific people to determine norms, standards, averages, etc. - Reliable
o Test will produce consistent results when it is given to the same group of people time and time again o Test-retest
• Give the test at time 1, and at time 2 (Look to see a correlation between time 1 and 2). Higher the correlation, the better reliability. o Split half (Part 1 at time 1, and part 2 at time 2)
- Validity
o Does it predict what it is supposed to be predicting?
o Content validity
o Predictive validity

NOTES AND BOOK

D. Is Intelligence Neurologically Measureable?

D.1) Brain Size

- Highly educated → more synapses
- Einstein’s brain
- Some areas were a little bit smaller than an average Canadian’s brain - Parietal Lobe’s were larger than the average Canadian’s brain

D2) Brain Function

- Reaction time
- People with high IQ have shorter reaction time, indicating they process information faster - Inspection time: How long before you understand and answer the stimulus o The inspection time is smaller for people with higher IQ

- Brain Waves
o The brain waves of people with high IQ are faster and more complex than people with lesser IQ - Glucose consumption
o Simples task is asked to sovle:
• High IQ, the brain is not working that hard; more efficiently • Low IQ, the brain is working hard, using a lot of glucose - Glutamate (pill to increase glutamate)
o Cognitive functions will improve
- Dopamine
o Cognitive functions will improve

NOTES

- Gave them 1-1 help
- Then put them up for adoption
- IQ scores increased by 30 points on average

- Schooling Effects
o During the school years they have higher IQ numbers compared to the summer years - Positive correlation between schooling and IQ

NOTES AND BOOK

C. Group Differences in Intelligence Test Scores

- Ethnic Differences
o Whites have scored higher on IQ test than blacks historically o Babies:
• Research: No significant differences between black or white babies in terms of IQ o Ancestry
o Socio-economic status
• Poverty makes a difference for IQ
• Poor children do not do as well as well off children in the IQ test o Discrimination
• Any group that is discriminated against tends to perform lower on the IQ test than the group doing the discrimination o Attitudes
o 10-15 points smarter than your Grandparents
NOTES ONLY

- Gender Differences
o No significant IQ score differences between men and women
o Women tend to better on verbal abilities
o Spatial abilities (reading maps, etc) Men tend to do better o Emotion-detection ability…women are better

- Differences between groups are ALWAYS smaller than the differences within a group NOTES AND BOOK

D. The Question of Bias

- Are IQ tests biased?
o Yes
• Reflect the knowledge, values and culture of the people who develop them o No
• Statistical sense
• Good predictive validity
• We can use IQ scores and predict with a certain degree of confidence whether you will do well in school or not - Stereotype Threat
o Negative stereotype about your group is activated; you may think they will judge me on this stereotype. Because of this anxiety, you will end up doing poorly - Stereotype Lift
o Positive stereotype is activate, it will improve your performance

TWO QUESTIONS ON THE MIDTERM

- Use your knowledge of evolutionary psychology to answer:
o 4 grandparents, which one of them will spend the more time, more money and most energy - IQ = Adult Shoe Size * 13
o Is this a valid measure?

EARN A POINT!!! BIG ONE!
Pg. 553-572
Minimum of 10 questions on the second midterm, a fifth of the midterm Part of Contemporary Research on personality
BIG 5 TRAITS

Personality:
- Typical way we think, typical way we feel, and typical way we behave

III. Contemporary Research on Personality

A.) The Trait Perspective → See Earn A Point

Evaluating the Trait Perspective

- Mischel blasted trait theory
o Trait theory does not take into account the environment
o Another major criticism, traits do not influence and affect behaviours like trait theory describes. - Mischel’s critique created:
o The person-situation controversy
• Different situations, different behaviours.
- Symour Epstein
o Mishcel was right and wrong
• We can use trait’s not to predict specific behaviours, but behaviours on average

B. The Social Cognitive Perspective

Introduction:
- Bandura
o According to the SCP, your personality is a result of a complex interaction between social and cognitive factors o Learning
o Conscious cognitive processes
o Self-efficacy beliefs
• Do you feel you are able to perform adequately, confidently etc. →high self efficacy beliefs o Situation-Environment
• Different situations, different reactions

B.1 Reciprocal Determination

A→B
B→A

- Both variables influence each other
- Good mood→positive thoughts

Behaviour, Internal Influences, External/Environmental Influences → In a triangle with two way arrows connecting all of them

- 3 ways in which indiviuals and their environment interact
o Different people choose different environments
o Our personality shapes how we interpret and react to the environment o Our personality helps create situations to which we react

B.2 Personal Control

- Locus of control
o Internal vs. External
• External: believes that something outside of themselves are in control • Internal: Captain of their own ship. Through their own actions they can create circumstances of their life - Learned helplessness

o Exposed to a situation uncontrollable
• Become helpless, hopeless and stop trying
- Optimism has to be balanced with healthy decisions

B.3 Assessing Behaviours in Situations

- What is the best way to predict future behavior?
o Past Behaviour

B.4 Evaluating the Social Cognitive Perspective

- Relies heavily on research
- Sensitizes researches on how situations affect people and how people affect situations - Forgets about:
o Traits, emotions, unconscious motives

C. The Biology of Personality

- Genes
o Seems to be a genetic component to personality
- Brain
o Structure & Function:
o Neurotransmitters
• Some people when they take anti depressants, become less anxious and become more outgoing o Sensation seekers need to go far to reach pleasure pathways activated

III. Exploring the Self

- Possible selves
o Part of your self concept that you have not developed yet
- Spotlight Effect
o We feel that others pay more attention to us as we actually do - Self-focus and memory
o Make up a story and put yourself in it, you will remember it better - Self-esteem

- Self-serving bias:
o Own our strengths and distance from weaknesses
-

IV. Reflection

- Bio-psycho-social perspective
o Looks at multiple factors
