Q

How does audition change during adulthood (2)?

A

1) The majority do not have significant hearing loss until after age 75
2) Individuals 75 - 79, at least 50% have hearing deficits that interfere with daily functioning. The biggest problem is a decreasing ability to perceive high-frequency sounds, which tends to occur earlier in men than in women and makes it difficult to understand human speech, especially when there is competing noise.

39
Q

What is Piaget’s constructivism theory of cognitive development?

A

For Piaget, the motivation for cognitive development comes from cognitive equilibrium. In other words, development occurs when disequilibrium is caused by a discrepancy between reality and current cognitive schemas. Equilibrium is restored through adaptation, which includes:

1) Assimilation is the incorporation of new knowledge into existing cognitive schemas
2) Accommodation is the modification of existing schemas to incorporate new knowledge

40
Q

What are the 3 types of genotype-environment correlations?

A

1) Passive genotype-environment correlation
2) Evocative genotype-environment correlation
3) Active genotype-environment correlation (e.g., niche-picking)

41
Q

What are teratogens?

A

Teratogens are substances that cause birth defects in the developing fetus and include drugs, chemicals, and certain maternal conditions

42
Q

When are teratogens most likely to cause major structural abnormalities?

A

Exposure during the embryonic stage (weeks 3 through 8) is most likely to cause major structural abnormalities

43
Q

What is fetal alcohol syndrome?

A

Fetal alcohol syndrome (FAS) is the most severe form of fetal alcohol spectrum disorder (FASD) and may result when the mother drinks heavily, especially during the second half of the first trimester.

Q

What are the 5 stages of brain development?

A

1) Proliferation: New cells are produced inside the neural tube beginning when the embryo is about 2.5 weeks old.
2) Migration: Immature “neurons” migrate to their final destination and combine with other cells beginning at about 8 weeks.
3) Differentiation: Neurons develop axons and dendrites and start to look different from other cells.
4) Myelination: Glial cells form an insulating sheath around some axons. Much myelination occurs postnatally.
5) Synaptogenesis: The timing of synaptogenesis (formation of synapses) depends on the specific area of the brain, but most occurs postnatally. Synaptogenesis appears to be influenced by both endogenous (e.g., genetic) and exogenous (e.g., experience) factors

2) Research shows it develops ages 4 - 7 months old

64
Q

A

Piaget’s used horizontal decalage to refer to the gradual acquisition of cognitive abilities within a specific stage of development. In other words, inconsistent performance in problems requiring the same cognitive abilities or the inability to apply a certain ability universally immediately.

65
Q

What are are 2 forms of transductive reasoning?

A

1) Magical thinking - the belief that thinking about something will actually cause it to occur
2) Animism - the tendency to attribute human characteristics to inanimate objects

66
Q

What is the nativist approach to language development?

A

The nativist approach attributes language acquisition to biological mechanisms and stresses universal patterns of language development. Chomsky (1968) proposed that an innate language acquisition device (LAD) makes it possible for a person to acquire language just by being exposed to it. Studies show that children master languages between the ages of 4 - 6 regardless of the complexity of their native language and that children from all cultures pass through the same stages of language development.

67
Q

What is the behaviorist approach to language development?

A

The behaviorist approach proposes that language is acquired like any other behavior through imitation and reinforcement.

68
Q

What is the interactionist approach to language development?

A

Interactionists regard language development to be attributable to a combination of biological and environmental factors (e.g., social interactions and child-directed speech)

69
Q

In regards to language development, what does responding with an expansion mean?

A

An adult is responding with an expansion when they add to the child’s statement but retains the child’s word order – e.g., when a child says, “Mommy bye-bye” and her father responds, “Yes, Mommy is going bye-bye.”

70
Q

In regards to language development, what does responding with an extension mean?

A

An adult is responding with an extension when they add information to the child’s statement – e.g., when a child says, “Mommy bye-bye” and her father responds, “Yes, Mommy is going to work now.”

71
Q

What is semantic bootstrapping?

A

Semantic bootstrapping refers to a child’s use of his or her knowledge of the meaning of words to infer their syntactical (grammatical) category.

72
Q

What is syntactic bootstrapping?

A

Syntactic bootstrapping refers to a child’s use of syntactical (grammar) knowledge to learn the meaning of new words.

Note that syntactic bootstrapping does not explain how children learn the precise meanings of words but only how children narrow the possible meanings of words.

73
Q

What are the 8 stages of language development?

A

Babbling begins by about 4 months old and involves the repetition of simple consonant and vowel sounds (bi-bi-bi)

80
Q

When do babies narrow their repertoire of sounds to those of their native language?

A

By 9 - 14 months of age

81
Q

What are the most likely first words for an infant?

A

Common first words include:
1) Nominals (particularly dynamic objects like cars or frequently use objects like spoon)
2) Labels for objects, people, or events (mama, dada)

Slightly less commonly first words include:
1) Action words (run)

4) 2.5 - 5 years = 50+ new words a month

85
Q

What does metalinguistic awareness mean and when does it develop?

A

Metalinguistic awareness is the ability to reflect on language as a tool and on themselves as language users. Children recognize that words are different from the concepts they represent and can use words humorously or metaphorically. Children develop metalinguistic awareness by 6 - 7 years old.

86
Q

What is underextension?

A

Underextension occurs when a child applies a word too narrowly to objects or situations

87
Q

What is overextension?

A

Overextension occurs when a child applies a word to a wider collection of objects or events than is appropriate

88
Q

How does a child’s age impact their response to divorce?

A

Preschoolers initially exhibit more problems than older children, probably because they are more likely to blame themselves and fear they will be abandoned by both parents, but older children exhibit worse long-term consequences (e.g., painful memories and fear they would have unsuccessful marriages themselves)

89
Q

How does a child’s gender impact their response to divorce?

A

Research shows a “sleeper effect” in which girls do not show negative consequences until adolescence when they develop noncompliant behavior, decreased self-esteem, and sexual promiscuity or as young adults, when they develop depression, anxiety, preoccupation with betrayal and abandonment, chose unstable husbands, or get divorced themselves.

90
Q

What are the 3 stages of understanding death and when do they occur?

A

The 3 stages of understanding death include: nonfunctionally, irreversibility, and universality

1) 2 - 5 years: Children typically think of death as temporary/reversible (e.g., separation or abandonment)
2) 5 - 9 years: Children develop awareness of irreversibility but personify death and think they can escape it
3) By age 10: Children recognize death’s nonfunctionally, irreversibility, and universality
