Q

Bronfenbrenner’s Ecological Model of Development

A

(2004) Based on the notion that development involves an interaction between the individual and their context or environment.

He described 5 Environmental Systems (or levels):

Microsystem

Mesosystem - interaction between elements of a child’s microsystem that influence development

Exosystem

Macrosystem

Chronosystem

Q

Critical Periods vs Sensitive Periods

A
  • Critical Periods- specific, predetermined periods of time during biological maturation when an organism is particularly sensitive to certain stimuli that can have either a positive or negative impact on development. - Sensitive Periods- longer in duration and more flexible than “critical periods”; not tied as closely to chronological age or maturation stage IE: attachment, language acquisition

Q

Genotype-Environment

(3 correlation proposals)

A
  • Passive

When children inherit genes that predispose them towards particular traits, and then parents provide a perfect environment that encourages that trait.

  • Evocotive

When a child’s genetic make up evokes reactions from parents and others that reinforce their genetic makeup (cooperative, attentive, smart)

  • Active

(Niche picking)

Q

Brain growth facts

A

Brain at 25% of it’s adult weight at birth

By age 2, it has reached about 80% of adult weight.

Growth due to increase of connections and formation of glial cells (responsible for myelinization) rather than generation of additional neurons

Cerebral Cortex is almost completely undeveloped, and **[the prefrontal cortex may not be fully developed until the mid-20’s]**

Least well-developed at birth: PREFRONTAL CORTEX

- Behavioral slowing- adversely affects performance on a variety of tasks
35
Piaget's Theory of Cognitive Development
Piaget's Constructivism is: - Humans construct higher knowledge by taking bricks from both biology and environment - Motivation for knowledge comes from a drive towards equilibrium, brought on by descrepancy between ones understanding of the world and reality - This descrepancy is resolved through ADAPTATION, which describes 2 processes: Assimilation and Accommodation.
36
Adaptation process according to Piaget (2 complimentary processes)
- Assimilation - the encorporation of new knowledge into existing cognitive schemas - Accommodation - the modification of existing schemas to incorporate new knowledge
37
Piaget's 4 Stages of Development
- Sensorimotor (B-2 years) - Pre-operational (2-7 years) - Concrete operational (7-11/12) - Formal operational (11 or 12 +)
38
Desribe Piaget's Sensorimotor Stage
- child learns through sensory information provided by objects and other people and the acts that can be performed upon them - Symbolic Thought - Object Permanence - Deferred Imitation - Make-believe play
39
Desribe Piaget's Pre-operational Stage
- Ages 2-7 Characterized by some limitations, such as: - Precausal reasoning (underlies Magical Thinking) - Animism; the tendency to attribute human characteristics to inanimate objects
40
Describe Piaget's Concrete Operational Stage
- (7-11/12 years old) - capable of CONSERVATION Ugh - which depends on the operations of reversability and decentration. - Treat objects as things (ie. dolls as babies) - the gradual acquisition of conservation is HORIZONTAL DECILAGE REALLY?! Ugh.
41
Describe Piaget's Formal Operational Stage
- 11/12 years old + - Beginning of this stage involves renewed EGOCENTRISM, which results in the phenomenons of Personal Fable and Imaginary Audience - Abstract thinking ability - Hypothetical deductive reasoning
42
(Elkind's) 2 Phenomenon that are a result in Renewed Egocentrism of beginning of Piaget's Formal Operational Stage 11/12 years old +
- Personal Fable - belief that one is unique and not subject to the natural laws that govern others - Imaginary Audience - belief that one is always the center of attention
43
Information-Processing theories of Development
- In contrast to Piagetians, development is viewed as taking place in specific cognitive domains. - IE: Vygotsky's Sociocultural theory
44
Desribe Vygotsky's SocioCultural Theory (an IPT)
- an Information-Processing Theory - emphasizes role of Society and Culture factors - Importance of Zone of Proximal Development
45
What does the Zone of Proximal Development describe, and who is the theorist?
- Vygotsky - Refers to the descrepancy between a child's current developmental level and the elve that they can reach with ***an adult or older peer's help***---\> SCAFFOLDING
46
Reminiscence Bump
The ability of adults to have better recall of events that occurred between the ages of 10 and 30
47
Describe important points of Memory Development
- Until age 9-10, children do not use memory strategies such as rehearsal or elaboration - Improvements on cognitive tasks that occur as children grow are partially due to **METACOGNITION** -or * Thinking about Thinking* * -* Among older adults, Recent Long Term (RLT) memory shows the greates age-related decline - probably due to problemns with the use of CODING STRATEGIES
48
The 3 primary approaches to Language Development
- Nativist (CHOMSKY) - language acquisition attriburted to biological mechanisms - stresses universal patterns of language development - Behaviorist - Interactionist
49
Describe the Nativist approach to Language Development
(CHOMSKY) - attributes language acquisition to biology - Chomsky proposed the existence of an innate LAD (Language Acquisition Device) that makes it possible for people to acquire language after being exposed to it -
50
Describe the Interactionist approach to language acquisition
- View that a combination of biological and environmental factors contribute to language development
51
Semantic bootstrapping
refers to a child's use of their knowledge of the meaning of words to infer their grammatical structure.
52
What are the 2 types of speech sounds?
- phonemes - smallest unit of sound understood in a human language - morphemes - smallest unit of sound that conveys meaning
53
3 Crying Patterns of Babies
- hunger - anger - pain
54
Describe language development in an infant
- 3-4 months: babbling - 9-14 months: sounds narrowed down to those of own language - 1-2 years: Holophrastic speech- 1-word to describe whole sentences or phrases - 18-24 months: Telegraphic speech- 2+ words together to make a sentence
55
2 types of errors that take place during language development
Under-extension: - word applied to narrowly (only use word "dish" for their own special dish Over-extension: -word applied too widely (dog for horse or other 4-legged animal)
56
Describe some gender differences in language
- Males talk for longer intervals and are more likely to interrupt - Females more likely to ask questions
