Development Psychology
A branch of psychology that studies physical, cognitive, and social change throughout the life span
Stability and Change
Stability are traits and behaviors that remain more or less constant. Change refers to the traits and behaviors that are more fluid and flexible. (throughout a persons life)
Nature v.s Nurture
The dispute over hereditary (nature) and environmental (nurture) factors to the development of an individual
Continuity vs. Discontinuity
The scientific debate over whether developmental change is gradual (continuous)or relatively abrupt (discontinuous)
Zygote
The fertilized egg; enters a two week period of rapid cell division and develops into an embryo
Embryo
The developing human organism from about two weeks after fertilization through the second month
Fetus
The developing human organism from a weeks after conception to birth
Teratogens
(“Monster Makers”) - Agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm
Fetal Alcohol Syndrome (FAS)
Physical and cognitive abnormalities in children caused by a pregnant woman’s heavy drinking. In severe cases, signs include a small, out-of-proportion head and abnormal facial features
Habituation
Decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a stimuli, their interest varies and they look away sooner
Rooting
An automatic, unlearned response of a newborn to a gentle stimulus applied to the corner of the mouth or to the cheek, in which the infant turns their head and makes sucking noises
Ex: The touch of a finger
Maturation
Biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience
Pruning
During various phases of brain development through the onset of puberty, the process in which excess or redundant neurons and synaptic connections are eliminated to enable more efficient neural processing

The awareness that things continue to exist even when not perceived
Parallel Play
In which a child is next to others and using similar objects but still engaged in their own activity
Pre-operational stage
Piagets theory, the stage (two to six/seven years of age) during which a child learns to not use language but does not yet comprehend the mental operations of concrete logic
Conservation
The principle that properties such as mass, volume, and number remain the same despite changes in the forms of objects (Piaget believed this to be a part of concrete operational reasoning)
Reversibility
Piagetion theory, a mental operation that reverses a sequence of events or restores a changed state of affairs to the original condition
Pretend Play
Pretend or make-believe play that includes an as-if orientation to actions, objects, and peers
Egocentrism
In Piagets theory, the pre-operational child’s difficulty taking anothers point of view
Theory of Mind
Peoples ideas about their own and others mental states — about their feelings, perceptions, and thoughts, and the behaviors these might predict
Concrete Operational Stage
Piagets theory, the stage of cognitive development (seven to eleven years old) during which children gain the mental operations that enable them to think logically
Formal Operational Stage
Piagets theory, the stage of cognitive development (Start of age twelve) during which people begin to think logically about abstract concepts
Lev Vygotsky
Russian-soviet psychologist who focused on how a child’s mind feeds on the language of social interaction
Scaffold
A framework that offers children temporary support as they develop higher levels of thinking
Zone of proximal development
The zone between what a child can do and can’t do; it’s what a child can do with help
Autism Spectrum Disorder (ASD)
Disorder that appears in childhood and is marked by significant deficiencies in communication and social interaction, and by rigidly fixated interests and repetitive behaviors
Stranger Anxiety
The fear of strangers that infants commonly display, starts at eight months old
Separation Anxiety
Normal apprehension experienced by a young child when away from the person or people to whom they are attached
Attachment
An emotional tie with another person; shown in children by their seeking closeness to their caregiver and showing distress on separation
Harlow Monkey Study
Separated infant monkeys from the mother and raised them individually
Cupboard theory
Infants form attachments to their caregivers primarily because they provide food
Critical period
An optimal period early in the life of an organism which exposure to certain stimuli or experiences produces normal development
Imprinting
The process by which certain animals form strong attachments during early life
Secure Attachment
Strong emotional bond where infants feel safe and confident exploring their environment while knowing they can return to their caregiver for comfort
Insecure Attachment
Bond where infants exhibit anxiety, avoidance, or ambivalence, towards their caregiver, often due to inconsistent or unresponsive caregiving
Anxious Attachment
Infants displaying clinginess and intense distress when separated from their caregiver due to inconsistent caregiving
Avoidant Attachment

Erik Eriksons Psychosocial Stages
Eight development phases where individuals face specific psychological conflicts that shape their personality
Psychosocial tasks
Challenges or crisis’ that individuals must overcome at various stages of development to achieve healthy psychological growth
Trust (vs. Mistrust)
Eriksons first stage where infants learn to trust caregivers for basic needs or develop mistrust if care is inconsistent
Autonomy (vs. shame & doubt)
Erikson second stage where toddlers strive to. develop personal control and independence, or feel shame and doubt if overly restricted
Initiative (vs. guilt)
Eriksons third stage where pre-schoolers begin to assert control through directing play and social interactions, or feel guilt if their efforts are stifled
Competence (vs. Inferiority)
Eriksons fourth stage where children work to master skills and feel content, or develop a sense of inferiority if they fail to measure up
Identity (vs. role confusion)
Eriksons fifth stage where adolescents explore and form their personal identity or experience confusion about their role in society
