Q

Authoritative

A

parents are both demanding and responsive. They exert control by setting rules and enforcing them, but they also explain the reasons for the rules. And, especially with older children, they encourage open discussion when making the rules and allow exceptions.

Q

Imprinting (Konrad Lorenz)

A

the process by which certain animals form strong attachments during an early-life critical period. Lorenz found in his experiments that the ducklings followed him - only valid for animals; not children)

Q

Strange Situation (Mary Ainsworth)

A

an experimental technique used to assess the quality of attachment in infants and young children (up to the age of 2). The procedure subjects the child to increasing amounts of stress induced by a strange setting (a lab), the entrance of an unfamiliar person, and two brief separations from the parent.

21
Q

Basic Tryst (Erik Erikson)

A

a sense that the world is predictable and trustworthy; said to be formed during infancy by appropriate experiences with responsive caregivers. (Erik compared how girls and boys were raised from when they were babies and how this would influence their future lives)

22
Q

Schema

A

a concept or framework that organizes and interprets information

23
Q

Assimilation

A

interpreting our new experiences in terms of our existing schemas

24
Q

Accommodation

A

adapting our current understandings (schemas) to incorporate new information

25
Q

Jean Piaget’s Stages of Cognitive Development

A

Children actively construct and modify their understanding of the world through assimilation and accommodation

26
Q

Lev Vygotsky’s critique of Piaget

A

Vygotsky emphasized how the child’s mind grows through interaction with the social environment

27
Q

Scaffolding

A

The passive, natural process through which new concepts are formed, especially in early childhood (with the help of parents or guardians)

28
Q

Zone of proximal development

A

The zone between what a child can and can’t do (training wheels on a bike)

29
Q

Implications for Parenting Teaching

A

Young children are incapable of adult logic. Children are not passive receptacles waiting to be filled with knowledge. Accept children’s cognitive immaturity as adaptive, it’s nature’s way of keeping children safe

30
Q

x - chromosomes

A

the sex chromosome found in both men and women. Females have two X chromosomes; males have one. An x chromosome from each parent produces a female child.

31
Q

Y - chromosome

A

the sex chromosome found only in males. When paired with an X chromosome from the mother, it produces a male child

32
Q

Testosterone

A

the most important of the male sex hormones. Both males and females have it, but the additional testosterone in males stimulates the growth of the male sex organs in the fetus and the development of the male sex characteristics during puberty

33
Q

Puberty

A

the period of sexual maturation, during which a person becomes capable of reproducing

34
Q

Primary sex characteristics

A

the body structures (ovaries, testes, and external genitalia) that make sexual reproduction possible

35
Q

Secondary sex characteristics

A

Nonreproductive sexual traits, such as female breasts and hips, male voice quality, and body hair

36
Q

Language

A

Our spoken, written, or signed words and the ways we combine them to communicate meaning

37
Q

Phoneme

A

in a language, the smallest distinctive sound unit

38
Q

Morpheme

A

in a language, the smallest unit that carries meaning; maybe a word or a part of a word (such as a prefix)

39
Q

Grammar

A

in a language, a system of rules that enables us to communicate with and understand others. In a given language, semantics is the set of rules for deriving meaning from sounds

40
Q

syntax

A

the set of rules for combining words into grammatically sensible sentences

41
Q

Babbling stage

A

beginning at about 4 months, the stage of speech development in which the infant spontaneously utters various sounds at first unrelated to the household language

42
Q

One-word stage

A

the stage in speech development, from about age 1 to 2, during which a child speaks mostly in single words

43
Q

Two-Word stage

A

beginning about age 2, the stage in speech development during which a child speaks mostly in two-word statements

44
Q

Telegraphic speech

A

early speech stage in which a child speaks like a telegram - “go car” - using mostly nouns and verbs

45
Q

Aphasia

A

impairment of language, usually caused by left-hemisphere damage either to Broca’s area (impairing speaking ) or to Wernicke’s area (impairing understanding)

46
Q

Broca’s area

A

controls language expression - an area of the frontal lobe, usually in the left hemisphere, that directs the muscle movements involved in speech

47
Q

Wernicke’s area

A

controls language reception - a brain area involved in language comprehension and expression; usually in the left temporal lobe

48
Q

Linguistic determinism

A

Whorf’s hypothesis that language determines the way we think

49
Q

Overextension

A

the phenomenon that children extend known words to describe referents outside their vocabulary
