Q

What are the five features that support the Chomskyan position

A
  1. Children go through similar stages of linguistic development
  2. children use word combos adults never would
  3. children not always corrected for grammatical erros yet learn to speak and sign correctly anyways
  4. children not eposed to language invent their own
  5. young infants can derive liguistic rules from a string of sounds

Q

Critisim of the “Genetic leash”

A
  1. Steriotypes vs. behaviour - doesn’t always match, sxeual promiscuity, chastity, and child rearing
  2. convenience vs. representative samples - surveying done eclusively on women up until 1973 = avoid oversimplification -
  3. What ppl say vs. what they do - choices vs actions
  4. Fred Flintstone problem - empasis on the Pleistocene ager -> agriculture, little access to potential mates, attraction = similarity and proimity

Q

faterneal (dizycotic) twins

A

twins that develop from two separate eggs fertilized by different sperm; they are no more alike genetically that are any other pair of siblings

24
Q

Define 3 important facts about heritability:

A
  1. an estimate of heritability applies only to a particular group living in a particular environment. Similarity vs diverse environment; richness and quality
  2. heritability applyies to variations within a group in a population = not individuals
  3. highly heritable traits can be modified by the environment
25
Intelligence quotient (IQ)
a measure of intelligence originally computed by dividing a persons' mental age by his chronological age and times 100; now derived from norms provided for standardized intelligence tests
26
Problems with IQ tests
* intelligence comes in many varieties, more than can be captured by a single score * culturally biased - middle class white
27
What factores can negatively affect IQ
1. Poor prenatal care 2. malnourishment 3. toxin exposures 4. stressful family environment
28
epigenetics
the study of changes in gene epression due to mechanisims other than structural changes in DNA
29
Noam Chompsky argues that the ability to take the ________________ of any utterance and apply rules of synatc to infer its underlying ____________ must depend on an innate faculty for language, a \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_sensitive to a \_\_\_\_\_\_\_\_\_\_\_\_\_\_
surface structure deep structure language acquistion device universal grammar
30
\_\_\_\_\_\_\_\_\_\_\_\_\_\_ and ______________ argue that males and females have evolved different sexual courtship strategies in response to survival problems faced in the distant past
sociabiologists and evolutionary psychologists
31
socialization
othe process by which children learn the behaviours, attidudes and expectations required of them by their society or culture
32
Which influences on the embriotic development can be harmful to the baby
* german measles * x-rays, radiation or toxins like lead * STD's * cigarette smoking * regular consumption of alchohol * drugs
33
contact comfort
in primates, the innate pleasure derived from close physical contact; it is the basis of the infant's first attachment
34
Separation anxiety
the distress that most children develp, at about 6 to 8 mo of age, when their primary caregivers temporarily leave them with strangers
35
What factors promote insecure attachment?
* abandonment and deprivation in the first year or two of life * parenting that is abusive, neglectful, or erratic b/c the parent is chronically irresponsible or clinically depressed * child's own genetically influences temperament * stressful circumstances int he child's family
36
telegraphic speech
a child's first wod combinations, which omit unecessary words
37
object permanence
the understanding, which develops throughout the first year, what an object continues to exist even when you cannot see or touch it
38
conservation
the understanding that the physical properties of objects, such as the number of items in a cluster or the amount of items in a cluster ior the amount of liquid in a glass, can remain the same even when their form or appearance changes
39
list Paiget's steps of cognitive development
1. sensorimotor stage - birth to 2 years - looking touching, putting things in the mouth, sucking grasping - object permanance big accomplitshment at this stage 2. preoperational stage - age 2- 7 - use of language and symbols , yet still lack the cognitive abilities necessary for understanding abstract principles and mental operations, their thinking is egocerntric, cannot yet grasp the concept of conservation 3. concrete operations stage - ages 7-12 - reasoning, abstract ideas, cause and effect, categorize
40
the Russian psychologist Lev Vygotsky adopted which theory?
sociocultural influences on children's cognitive development Children learn by using private speech believe that the stages were not distinctive, may proceed in any number of directions - enviro, cultural and learning
41
Why have some of Piaget's ideas have been overturned?
* cognitive abilities develop in overlapping waves rather then descrete steps * preschoolers are not as egocentric as one thought, they can take another persons' perspective - children reveal cognitive abilities much earlier than piaget believed possible * cognitive development in influenced by a child's culture
42
Theory of mind
a system of beliefs about the way one's own mind and the mind of others work, and how individuals are affected by their beliefs and feelings
43
Power assertion
a method of child rearing in which the parent uses punishment and authority to correct the child's misbehaviour
44
induction
a method of child rearing in whch the parent appeals to the child's own abilities, sense of responsibility, and feeling for others in correcting the child' misbehaviour
45
gender identity
the fundamental sense of being male or female; it is independent of whether the person conforms to the social and cultural rules of gender
46
gender typing
the process by which children learn the abilibites, interests, and behaviours associated with being masculine or feminine in their culture
47
inter-sex conditions (inter-sexuality)
conditions in which chromosomal or hormonal anomalies cause a chold to be born with amiguous genitals, or genitals that conflict with the infants' chromosomes
48
gender schema
a cognitive schema (mental network) of knowledge, beliefs , metaphors and ecpectations about what it means to be male or female
49
puberty
the age at which a person becomes capible of secual reproduction
50
menache
the onset of menstration during puberty
51
list the 8 stages of development
1. trust vs mistrust 2. antonomy vs shame and doubt 3. initiative vs gulit 4. competence vs inferiority 5. Identity vs role confustion 6. intimacy vs isolation 7. generativity vs stagnation 8. ego integrity vs despair
52
fluid intelligence
the capacity for deductive reasoning and the ability to use new information to solve problems' it is relatively independent of education and tends to decline in old age
53
crystallized intelligence
cognitive skills and specific knowledge of information aquired over a lifetime; it is heavily dependant on education and tends to remain stable over the lifetime
54
Social Darwinism
The notion that wealthy and successful are more reproductivly fit than other people
