Q

Caspi (1987)

A

Temper Tantrums

  • 8-11 aged children
    Mothers rated the kids occurring behavior
    (Kicking, biting, screaming, throwing things, etc. 38% boys, 29% girls)

Later in adulthood predictions:
- Lower educational achievement
- Lower work status, more erratic work
- More likely to divorce (2x)

Q

3 types of stability

A
  1. Rank Order stability (vs. change)
  • Ones position along a dimension
  • can be high even with much mean change
  • Examined by test-retest correlations
  • Same people at time 1 need to be retested at time 2, same people at both times. All about individual differences.
  1. Mean Level Stability
  • Whether mean changes by time, compares young to old.
  • As we develop, we might change in different respects.
  • Can be different people, but provides indicating that age affects individuals.
  1. Personality Coherence
  • More complex. As people age, their behaviors change.
  • Traits are stable overtime even though activities change. Behavior expression is different.
  • Similar to rank order stability. Same jerky person, just different jerky things.

Q

Roberts & DelVecchio (2000)

A

When does personality become the most stable research

  • Teenager r = .47
  • 20 Years Old r = .57
  • 30 Years Old r = .62
  • 50 Years Old r = .75

So by 50, personality becomes most rigid

Q

Why might people have negative self views seek negative social feedback?

A
  1. Epistemic reasons
  • To know themselves
  • Discrepant social feedback is confusing and not familiar
  • Therefore, we feel most “ourselves’
  1. Pragmatic reasons
  • Other views self = as self views self
  • No need for feigning, being someone other than oneself
  • Easier to get along with others
  • Easier to interact

Q

Choosing Interaction Partners

A
  1. Self enhancement
  • to be viewed favorable, therefore choosing person A.
  1. Self verification
  • Motivated to verify your self concept. We seek confirmatory feedback.

Q

Human genome

A

June 26, 2000 first draft of entire genome

  • 30-40k genes
  • heretical from mother and father

Most genes are identical
- Indeed 80% w/ sea squirts and 98% with chimps
- Unique (non-shared) genes in part responsible for these differences.

Height: 90% genes, 10% envi

Q

Heritability

A
  • % of variance
  • Of a phenotypic (Observed and manifested) trait

.5 = 50% genetic influence
.2 = 20% genetic influence

Height is .9
Weight is .5
Mate characteristics pref. Is .1

Q

Heritability Misconceptions

A
  1. Population level stat
    - Height is 90% heritable = okay
    - Michaels height is 90% = ?
  2. Heritabilities are not fixed
    - Height in Middle Ages vs. today
    - Perhaps differences by culture (poor countries and height)
17
Q

what are behavior genetic methods?

A
  • Selectrive breeding
  • Family studies
  • Twin studies
  • Adoption studies
18
Q

Selective Breeding

A

If you breed certain members of the population to increase those characteristics, it will work.

Most commonly dogs
* Pit bulls = aggression
* Labrodors = sociability
* Chesapeake Bay retriever = fetch

19
Q

Family Studies

A

Traits should be more similar, for more similar family members

Shared genes:
- Parents = 0%
- Each parent w/ a child = 50%
- Siblings = 50%
- Grandparents = 25%

Potential Problems:
* Closer family live together
* Confound of genes and environment.

20
Q

Twin Studies

A
  • Identical twins are more similar than fraternal.
21
Q

Adoption Method

A

If envt has effect, children should be similar to adoptive parents.

If genes have effect, children should be similar to biological parents

22
Q

Genetic heritability findings

A
  • E & N: Heritability ~ .5
  • 50% of E,N predicted by genes
  • Typical finding
  • Mz = .51
    *Dz = .21
  • Heritability= 2*(.51-.21) = .6

Temperament like variables

  • Activity level: is found heritability of movement = .40
    -Other temperament: Emotionality, sociability, and persistence = .5
23
Q

Heritability in personality

A
  1. Almost any trait ~ .5
    - Both inborn and socialized (Activity level/morality)
  2. Genes major contributor
    - Stability or lack of Change for personality
24
Q

Big 5 Results

A
  • Goldberg
  • 10 items per big 5 = 50 items.
    1-5 scale
  • 1 being very inaccurate
    -5 being very accurate
25
Q

Were scales reliable? Means?

A
  • Cornbach’s alpha, internal consistency
    E = .90, mean= 3.37
    A = .87, mean= 4.27
    C = .88, mean= 3.63
    N = .86, mean= 2.72
    O = .77, mean = 3.80

Pretty good for 10 item scales

26
Q

Common phys measures

A
  • Involving playing electrodes on skin
  • Sweat response
  • Blood flow
  • Heart rate
  • Brain activity
  • Muscle tension
27
Q

Forms of sexual selection

A
  1. Intrasexual
    * Males would have dispositions and attributes that allow it to compete with other individuals of its own sex.
    Ex. Elephant seals protecting the beach with aggression, access to females.
  2. Intrasexual
    * Gental. There are certain attributes that you could possess that makes the other gender choose you.
    Ex. Male ducks having bright colors to attract mates.
28
Q

Male Sex Differences

A
  • Lots of sperm
  • Don’t gestate, nurse young
  • No limit of reproduction potential
  • Pressures for many partners.
29
Q

Female Sex Differences

A
  • Limited # of eggs
  • Gestation & nursing of young
  • Limit to reproduction potential
  • Pressures for responsible partners
30
Q

Parental Investment Thierry (Darwin 1871; Trivers 1972)

A
  1. The sex that invests more in parenting becomes more choosy. Because parenting is costly, quality over quantity.
  2. The sex that invests less in parenting becomes more horny. Because the sheer number of conquest matters, quantity over quality.
