the methods used in studying human development, including types of data and strengths and limitations of different research designs
Self-Report Measures : participants answer questions themselves
Questionnaire/survey: set of mc questions
Open-ended interview: no parameters; conversation style, flexible questions
Structured Interview: asks each participant same questions; differences in responses = actual differences in participants
Pros: easy and cheap to collect, Cons: subject to error, inaccurate memories, lack of insight, social desirability
Observational Measures Researchers watch and monitor behavior, then organize information
Naturalistic observation: viewing and recording behavior in a natural, real world setting
Structured Observation: viewing and recording behavior in controlled setting
Pros: potential to capture more accurate behavior; Cons: very resource-intensive, observer bias, structure not reflect real behavior
Physiological Measures:observe physiological indicators of cognition, emotion, and behavior (ex: heart rate, cortisol, etc)
Pros: Not subject to researcher interpretation (In theory); Cons: usually requires special equipment/training, difficult to enroll participants, results still subject to misinterpretation
Correlational studies: Examines relationship between two variables
Pros: easy to conduct, cross-sectional(fast results); Cons: difficult to control confounds, correlation does not equal causation
Experimental Research: Manipulating one variable and measuring its effect on another (ex: exclusion vs. anxiety)
Pros: considered “gold standard”, can claim causality; Cons: ethical concerns, can’t control relevant variables/confounds, and requires larger samples to fulfill multiple conditions/control groups
Qualitative Research: Collecting and analyzing non-numerical data to understand concepts, opinions and exps
Pros: Provides rich data, doesn’t reduce thoughts/actions to numbers; Cons: time consuming, research bias
Cross Sectional: groups of different ages at one time
Pros: provides information on age-related change; Cons: cannot examine change over time, or cohort effects
Longitudinal: One group is studied at many points in time
Pros: provides developmental analysis, change over time; Cons: time-consuming, attrition, practice effect
Sequential: asses multiple cohorts over time
Pros: can examine cohort effects; Cons: expensive, possibility of practice effects
major theories and theorists (e.g., Erikson, Sociocultural theory, Piaget- know key terms in Piaget’s theory, such as “assimilation”)
Freuds Psychosexual Theory: discontinued stages, passive are motivated by inborn basic drives
Oral > Anal > Phallic > Latency > Genital
Eriksons Psychosocial Theory: Active minds interact with social world to resolve psychosocial tasks
Each stage provides a conflict and social interactions determine stages outcome, never too late to resolve
Infancy > Early Childhood > Play Age > School Age > Adolescence > Early Adulthood > Adulthood > Old Age
One of the first lifespan views of development, view with society/culture included
Behaviorist Theory: passive shaped by environment; only observable behavior is examined
Classical/Operant Conditioning
Banduras Social Learning Theory: emphasizes role of modeling/observing learning over people behavior and consequences to that behavior
Can learn by thinking of potential consequences to actions
Piagets Cognitive Development Theory: interact with the world to create their own schemas
Sensorimotor > Pre-operational and Concrete Operational > Formal Operations
With each advancing stage, people use more sophisticated schemas to understand worlds complexities
Information Processing Theory: Mind is computer that takes in, stores, processes, and manipulates information
Vygotsky’s Sociocultural Theory: focuses on role of society/culture in cognitive development on children learning through interactions with others who are more competent
Throughout interactions, children learn rules and practices of society/their culture
Brofenbrenner’s Bioecological Systems Theory: Connects are organized into series of systems
Inds are embedded and interact with one another to influence development; systems interact too
Microsystem (Child) > mesosystem (family, school, peers) > exosystem (parents work, neighbors) > macrosystems (politics, culture laws/policies, social class)
the dynamic interactions between heredity and environment (e.g., gene-environment correlations) and how we study them
Twin studies determine whether post birth environments or genetics is cause for similar traits
For biological siblings, timings differences can shape differences (macro systems, prenatal environment, family system, etc)
Gene-Environment interaction: When different genotypes respond to environmental variation in different ways, genes cannot be understood without studying environments
Passive: parental genes > parents behavior builds environment for child
Active: child genes > child’s behavior, children select/shape their environments when old enough
Evocative: child genes > others peoples behavior, evoke responses from others
prenatal development (including stages, environmental influences), and patterns of growth/development (e.g., cephalocaudal)
Stages: germinal (first 14 days, where rapid cell growth and differentiation occurs) > embryonic (3-8 weeks, when organs and major body systems develop (organogenesis)reflexes and defects)> fetal (9 weeks to birth, rapid growth, complex organ development, spontaneous movement)
Patterns of development: Cephalocaudal (from head down), and Proximodistal ( from center out)
Top heavy head and trunk grows before limbs then limbs etc
Mothers nutrition, ingested teratogens (consider critical periods, does and ind. differ) and stress all effect baby
Babies learn mothers voice and develop preferences in womb
Birthing process can be private/public, related to social status, religious practices, and more based on culture
Treatment of the mother, access to nutritious food, familial support, also effected by culture
Apgar Scale: accesses baby’s immediate condition
Appearance, pulse, grimace, respiration
Brazelton Neonatal Assessment Scale: assess subtle behavior aspects of newborns condition
Motor capacities, responsiveness to objects/people and self-control
concepts relating to early brain development (e.g., neurogenesis)
Neurogenesis: creation of neurons, begins during prenatal development, and proceeds rapidly
Neuronal migration: neurons align themselves with glial cells (provide neurons with supplements) and migrate to different parts of the brain
Leads to organization if brain and localizes functions
Synaptogenesis: forming of new synapses, begins prenatally and makes more connections than needed
Synaptic pruning: synapses not used die off
Exp-expectant brain development: in anticipation to species wide events and stimuli, sensory dep. interrupts the development
Exp-dependent brain development: in response to specific ind. learning exps, playing musical instruments isn’t universal
Association between screen time and underdeveloped white matter in preschoolers
physical changes that occur with puberty, influences on pubertal timing, and the psychosocial effects of early and late puberty
Genetics influence rate of growth by triggering amount of hormones release
Migration (poor and rich) > dramatic changes between generations
Puberty is driven by hormones regulated by the hypothalamus-pituitary-gonadal axis (HPG axis)
Females marked by menarche and growth of uterus and ovaries; males marked by spermarche and gritty of testes/penis/scrotum
How puberty is measure: age of menarche/spermarche, genetic onset of puberty symptoms and personal perception
Levels of testosterone can shift dramatically in response to stress and illness
Nutrition, stress, and contextual factors > pubertal timing
early motor development, including reflexes, types of motor behavior (e.g., gross), and the relationship between motor behavior and perception assessment of newborn functioning (e.g., Apgar score)
Infants center world with rich set of involuntary image reflexes (rooting, Pelmar grasp)
Gross motor development: use of large muscles for large movements, how we move through environment
Fine motor skills: development and coordination of small muscles (reaching, grasping, manual dexterity)
Maturation and context drive motor development (pruning, development of cerebellum, myelination)
Need for communication, writing and eating with intensive drives motor development culturally
Dynamic systems theory : maturation motivation and context intertwine > motor development
Affordances: how infants gauge what they can do with what they see in environments (objects)
Intermodal perception : integrate information from multiple sensory systems to understand the world (ex. Localizing sounds)
Perceiving affordances is more adaptive than auto fear response (visual cliff)
Learn to perceive relationship with environment after developing crawling/walking experience
