Exam 3 Flashcards
Nature
genetic background
Nurture
the environment (family life, the way you’ve grown up within the context of your family/interaction w/ peers, socioeconomic status, access to resources, a fetus’ experience in uterus, all of your life experiences contribute to your environment.) Includes the physical environment, even in utero, and the social environment
Behavior genetics
the study of genetic and environmental influences on behaviors. By examining genetic influence, more information can be gleaned about how the environment operates to affect behavior.
e.g. Individual differences (the ways that we vary one from the next)
Evolutionary Psychology
the study of human cognition and behavior with respect to their evolutionary origins.
e.g. Universal behaviors, “human nature”
sex differences (Ex: why are most acts of violence perpetrated by men around the world?)
Nature versus nurture: Competing historic views
Nurture:
John Locke: tabula rasa (blank slate)
Skinner and Watson: radical behaviorism
Nature:
Plato: truth, goodness, beauty exist as innate universals in the mind
Rousseau: the human infant is innately good
Leibnitz: there are veins in the marble of the blank slate (there is something already written upon our human nature as we come into the world)
Genotype
specific genetic makeup (we each have our own unique genotype (unless identical twin))
Genes program the formation of protein molecules
Phenotype
Observable characteristics (path between genotype and phenotype is long and not direct) *Most of our human behaviors are effected by thousands of genes that are all having tiny effects
polygenic transmission
the kind of inheritance in which the trait is produced from the cumulative effects of many genes.
The environment affects what in relation to genotype and phenotype?
affects when and how genotype is expressed in phenotype
remote causes of behavior
The evolutionary function of behavior
OR the adaptive significance of a behavior: how the behavior influenced chances of survival and reproduction
Remote causes work by selecting for genes that code for current biological mechanisms that get expressed in the right environments
Proximate causes of behavior
Current biological mechanisms AND
Current environmental experience, including culture
What causes behavior in the here-and-now, within a person’s lifetime.
Remote cause or function of laughter?
Helps people share same emotions
Offers feedback to partner about laugher’s intentions and emotional state
Proximate causes of laughter?
Vibration of vocal cords, exhaling - physical mechanisms most similar to our closest genetic relatives (chimps and bonobos)
Social experiences and tickling
Physical mechanism most similar to our closest genetic relatives (chimpanzees and bonobos)
Genes affect our
IQ and traits
IQ and traits affect
responses we evoke from others (evocative effect)
Environments we select (selection effect)
Nature via Nurture
Evolution: genes shape universal behaviors and possibly some gender differences
Behavior genetics: genes shape our personalities and likelihood of disorder
But, nurture is profoundly important in both processes
Domain general model:
different cognitive skill (e.g. reasoning, lang, counting) change together
Schemas:
organized patterns of thought and action
Assimilation
New experiences are incorporated into existing knowledge (schemas)
Accommodation
New experiences change existing knowledge (schemas)
After repeated accommodation, child’s underlying schemas change and
Move to new stage
Sensorimotor Stage (ages 0 to 2)
Thought and action are virtually identical
Exploration through sense and behavior
Lack of object permanence (things exist even if you can’t see them)
Complete egocentrism
Embedded in own point of view
Preoperational Stage (ages 2 to 7)
Symbolic thought develops
Words and images
Object permanence is firmly established
Still egocentric (think ppl see the world exactly the way they do)
The child cannot coordinate different physical attributes of an object or different perspectives
Centration: focus on one perceptually striking aspect of an object w/o considering other relevant features. (poor Jonathan)
Concrete Operational (ages 7 to 12)
Operations: mental actions that can be used to manipulate, transform, and then return an object to its original state
Can perform reversible mental operations on representations of objects
Begins to understand conservation
Basic properties of an object or situation remain the sane even tho the superficial properties are changed
*No longer egocentric, can take other POVs
Formal Operational Stage (ages 12 to 15)
Can apply logic more abstractly
Hypothetical thinking develops
Third-eye problem (how rational is their answer)
Was Piaget right?
Yes and no.
Yes
*stages occurs in this order across cultures
No
Children are not at the same stage for all of their skills
Change is often continuous rather than abrupt
What promotes prosocial emotions and a strong conscience?
Power assertion
Love withdrawal
Induction: verbal reasoning in which parent induces the child to think about harmful or helpful consequences of his or her actions
Why does induction work best?
It enables them to take someone else’s perspective
Attachment
Universal
Strong emotional bond
forms between the important adults and the baby. A specific relationship between child and other person.
Emerges 7-8 months
The Strange Situation
Baby cries when mom leaves. Baby is a little better when stranger comes. Very happy when mom comes back.
