30
Motor development
Changes in the ability to coordinate and perform bodily movements
31
Cognitive development
Changes in all of the mental activities associated with thinking, knowing, remembering, and communicating
32
Schemas
Concepts or mental models that represent our experiences
33
Assimilation
In Piaget’s theory, the process of using an existing schema to interpret a new experience
34
Accommodation
In Piaget’s theory, the process of revising existing schemas to incorporate information from a new experience
35
Sensorimotor stage (birth to 2 years)
Children develop knowledge through their senses and actions but cannot yet think using symbols, namely language. During this stage, children learn that objects continue to exist even when the objects are hidden.
36
Preoperational stage (2 to 7 years)
Children master the use of symbols but struggle to see situations from multiple perspectives or to imagine how situations can change. During this stage, children classify objects, but only according to a single feature, such as color or shape.
37
Concrete operational stage (7 to 12 years)
Children become capable of using multiple perspectives and their imagination to solve complex problems, but they are able to apply this thinking only to concrete objects or events.
38
Formal operational stage (12 years and up)
Adolescents become able to reason about abstract problems and hypothetical propositions
39
Object permanence
The awareness that objects continue to exist even when they are temporarily out of sight
40
Neural proliferation
The creation of new synaptic connections
41
Synaptic pruning
The trimming back of unnecessary synapses according to a “use it or lose it” principle—connections that get used are maintained, and unused connections are eliminated
42
Myelination of axons
The process of insulating axons in myelin, which speeds their conductivity and allows information to move more rapidly through the brain and body
43
Social referencing
A process of using others’ facial expressions for information about how to react to a situation
44
Attachment
The strong, enduring, emotional bond between an infant and a caregiver
45
Imprinting
A mechanism for establishing attachment early in life that operates according to a relatively simple rule of attaching to the first moving object an organism sees.
46
Secure attachment
Secure attachment. Children who have a secure attachment relationship with their caregiver use that caregiver as a secure base. They explore, play with the toys, and even make wary overtures to the stranger, so long as the caregiver is present.
Whenever the caregiver leaves, these infants show minor distress. When the caregiver returns, the infants show great enthusiasm and are quickly reassured.
47
Insecure attachment
When the child doesn't use a caregiver as a secure base and is not reassured after a separation, the child has an insecure attachment style to the caregiver. There are two patterns of insecure attachment.
48
Insecure/avoidant attachment
They act distant and aloof while the caregiver is present, and although they sometimes search for them in their absence, they typically ignore them when they return. Critically, although these infants look unruffled on the surface, their apparent calmness is actually a mask for distress: Their heart rates accelerate when their parent leaves and remain high when they return
49
Insecure/ambivalent attachment
They do not explore, even in the caregiver's presence, and they become quite upset when the caregiver leaves. Upon reunion, they act ambivalent-crying and running to the caregiver to be picked up, but then kicking or slapping and struggling to get down.
50
Temperament
A person’s characteristic patterns of emotion and behavior that are evident from an early age and argued to be genetically determined
51
Childhood
The period of life spanning the end of infancy (about age 2) and the start of adolescence
52
Symbolic representation
The use of words, sounds, gestures, visual images, or objects to stand for other things
53
Operations
In childhood, the manipulation of schemas
54
Conservation
The idea that the physical properties of an object, such as mass, volume, and number, remain constant despite superficial changes in the object's shape or form.
55
Egocentrism
In Piaget’s theory, the difficulty that preoperational children have with thinking about how objects or situations are perceived by other people
56
Theory of mind
The understanding that we and other people have minds, that these minds represent the world in different ways, and that these representations can explain and predict how others will behave.
57
Sociocultural view of development
Lev Vgotsky’s proposal that the child’s mind grows through social interaction with knowledgeable others
58
Scaffolding
A process of promoting cognitive development by actively challenging and supporting children as they attempt things that are beyond their current capabilities.
59
Sex
The biological and anatomical differences that make a child male or female
60
Intersex
Have both male and female sex organs
61
Gender identity
The physiological identity of being male, female, or nonbinary
62
Cisgender
To have a gender identity that matches their biological sex
63
Gender socialization
The process by which people internalize social expectations and attitudes associated with their perceived gender
64
Gender schema
A mental representation for the concept of gender that includes assumptions about how people with different genders are supposed to think, feel, and act.
65
Transgender
Identifying with a different gender than the sex they were born with
66
Gender constancy
A person’s gender identity is consistent regardless of how they may act or dress, so acting like a boy won’t turn a girl into one

74
Secondary sex characteristics
Non-reproductive body structures, such as hips, torsos, voices, and body hair that make the body look more “adult”
75
Preconventional stage
In Kohlberg's theory, a period in moral development in which people make moral judgments based on self-interest, such as avoiding punishments and gaining rewards.
76
Conventional stage
In Kohlberg's theory, a period in moral development in which people make moral judgments based on caring for others and upholding social roles and rules.
77
Postconventional stage
In Kohlberg's theory, a period in moral development in which people make moral judgments based on ideals and broad moral principles.
78
Social identity
A sense of identity that is rooted in group memberships
79
Emerging adulthood
The period between adolescence and adulthood, roughly the ages of 18 to 25, when people take time to finish schooling, gain financial independence from their parents, and establish careers and families.

83
Socioemotional selectivity theory
Laura Cartensen’s theory that our perception of how much time we have left in life leads us to value emotional over informational goals
84
Disorganized/Disoriented attachment
When a child exhibits behavioral disorganization or disorientation in the form of wandering, confused expressions, freezing, undirected movements, or contradictory (i.e. “unorganized”) patterns of interaction with a caregiver
85
Understanding "wanting"
Different people want different things, and to get what they want, people act in different ways.
86
Understanding "thinking"
Different people have different, but potentially true, beliefs about the same thing. People's actions are based on what they think is going to happen.
87
Understanding that "seeing leads to knowing"
If you haven't seen something, you don't necessarily know about it (ex. the Dad on the telephone). If someone hasn't seen something, they will need extra information to understand.
88
Understanding "false beliefs"
Sometimes people believe things that are not true, and they act according to their beliefs, not according to what is really true.
89
Understanding "hidden feelings"
People can feel a different emotion from the one they display.
90
archetypes
tropes or characters that represent aspects of the
collective unconscious (e.g., “the hero”).
91
the collective unconscious
an innate series of patterns and symbology that reflect universal truths of the human existence.
92
The Trauma of Birth
A book written by Otto Rank which described his theory that the shock of going from an unconscious to a conscious state (i.e., pre-birth to alive and in the world) was something that people spend their whole lives trying to overcome. He believed it was the root of various psychological problems that occur later in adulthood.
93
rooting
Babies turn their heads towards location of nipple or other food source with their mouths open
94
Sucking
How we get food as a baby, babies suck on objects placed in their mouths
95
Grasping
Babies grasp onto things placed in their hand. Theorized to be an evolutionary tactic in monkeys
96
head to toe
most infants are able to pick up and coordinate movement of their head before they are able to coordinate movement in their feet (i.e. walking).
97
internal to external
infants are first able to coordinate movement in their torso before they can coordinate movement of their legs and arms.
