Chronological development A method of organization that describes events in the order in which they occurred Lifespan development the field of study that examines patterns of growth, change, and stability in behavior that occur throughout the entire life span Nature and nurture the debate of weather you are shaped by your environment or genes Continuous development view that development is a cumulative process: gradually improving on existing skills Discontinuous development view that development takes place in unique stages, which happen at specific times or ages teratogens agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm Fine motor coordination - involves small muscle groups - usually includes finger dexterity and/or skilled manipulation of objects with the hands Gross motor coordination -- Ability to coordinate large muscle movements as in running, walking, skipping, and throwing. Maturation biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience Reflexes specific patterns of motor response that are triggered by specific patterns of sensory stimulation Rooting reflex a baby's tendency, when touched on the cheek, to turn toward the touch, open the mouth, and search for the nipple Visual cliff a laboratory device for testing depth perception in infants and young animals Critical periods Periods in the developmental sequence during which an organism must experience certain kinds of social or sensory experiences in order for normal development to take place Sensitive periods time periods when specific skills develop most easily Imprinting the process by which certain animals form strong attachments during an early-life critical period Growth spurt The relatively sudden and rapid physical growth that occurs during puberty. Each body part increases in size on a schedule: Weight usually precedes height, and growth of the limbs precedes growth of the torso. Puberty the period of sexual maturation, during which a person becomes capable of reproducing Primary sex characteristics the body structures (ovaries, testes, and external genitalia) that make sexual reproduction possible Secondary sex characteristics nonreproductive sexual characteristics, such as female breasts and hips, male voice quality, and body hair Menarche the first menstrual period Spermarche first ejaculation Menopause the time of natural cessation of menstruation; also refers to the biological changes a woman experiences as her ability to reproduce declines Schemas Concepts or mental frameworks that organize and interpret information. assimilation interpreting our new experiences in terms of our existing schemas accommodation adapting our current understandings (schemas) to incorporate new information sensorimotor stage in Piaget's theory, the stage (from birth to about 2 years of age) during which infants know the world mostly in terms of their sensory impressions and motor activities object permanence the awareness that things continue to exist even when not perceived Preoperational stage in Piaget's theory, the stage (from about 2 to 6 or 7 years of age) during which a child learns to use language but does not yet comprehend the mental operations of concrete logic Mental symbols represent objects in the real world Pretend play make-believe activities in which children create new symbolic relations, acting as if they were in a situation different from their actual one Conservation the principle (which Piaget believed to be a part of concrete operational reasoning) that properties such as mass, volume, and number remain the same despite changes in the forms of objects Reversibility the capacity to think through a series of steps and then mentally reverse direction, returning to the starting point Animism Belief that objects, such as plants and stones, or natural events, like thunderstorms and earthquakes, have a discrete spirit and conscious life. Egocentrism in Piaget's theory, the preoperational child's difficulty taking another's point of view Theory of mind an awareness that other people's behavior may be influenced by beliefs, desires, and emotions that differ from one's own Concrete operational stage in Piaget's theory, the stage of cognitive development (from about 6 or 7 to 11 years of age) during which children gain the mental operations that enable them to think logically about concrete events Systematic thinking approaches problems in a rational, step-by-step, and analytical fashion Formal operational stage in Piaget's theory, the stage of cognitive development (normally beginning about age 12) during which people begin to think logically about abstract concepts Abstract thinking capacity to understand hypothetical concepts Scaffolding Adjusting the support offered during a teaching session to fit the child's current level of performance Zone of proximal development (ZPD) Vygotsky's concept of the difference between what a child can do alone and what that child can do with the help of a teacher Crystallized intelligence our accumulated knowledge and verbal skills; tends to increase with age Fluid intelligence our ability to reason speedily and abstractly; tends to decrease during late adulthood Dementia a slowly progressive decline in mental abilities, including memory, thinking, and judgment, that is often accompanied by personality changes Phonemes in language, the smallest distinctive sound unit Morphemes The smallest units of meaning in a language. Semantics the set of rules by which we derive meaning from morphemes, words, and sentences in a given language; also, the study of meaning Grammar in a language, a system of rules that enables us to communicate with and understand others Syntax Sentence structure Cooing early vowel-like sounds that babies produce Babbling stage of language development at about 4 months when an infant spontaneously utters nonsense sounds One-word stage the stage in speech development, from about age 1 to 2, during which a child speaks mostly in single words Telegraphic speech early speech stage in which a child speaks like a telegram—"go car"—using mostly nouns and verbs. Overgeneralization of language rules Applying a regular grammatical rule in an irregular situation. Example: "I runned", "he hitted", "you buyed" Ecological systems theory views the person as developing within a complex system of relationships affected by multiple levels of the surrounding environment Microsystem the people and objects in an individual's immediate environment Mesosystem connections between microsystems Exosystem social settings that a person may not experience firsthand but that still influence development Macrosystem consists of cultural values, laws, customs, and resources Chronosystem historical changes that influence the other systems Authoritarian parenting style of parenting in which parent is rigid and overly strict, showing little warmth to the child Authoritative parenting parenting style characterized by emotional warmth, high standards for behavior, explanation and consistent enforcement of rules, and inclusion of children in decision making Permissive parenting A parenting style characterized by the placement of few limits on the child's behavior. Attachment styles The expectations people develop about relationships with others, based on the relationship they had with their primary caregiver when they were infants Secure attachment a relationship in which an infant obtains both comfort and confidence from the presence of his or her caregiver Insecure attachment demonstrated by infants who display either a clinging, anxious attachment or an avoidant attachment that resists closeness Avoidant attachment attachments marked by discomfort over, or resistance to, being close to others Anxious attachment attachments marked by anxiety or ambivalence. an insecure attachment style disorganized attachment characterized by the child's odd behavior when faced with the parent; type of attachment seen most often with kids that are abused Temperment a person's characteristic emotional reactivity and intensity Separation anxiety the distress displayed by infants when a customary care provider departs Parallel play activity in which children play side by side without interacting Pretend play make-believe activities in which children create new symbolic relations, acting as if they were in a situation different from their actual one Imaginary Audience adolescents' belief that they are the focus of everyone else's attention and concern Personal fable type of thought common to adolescents in which young people believe themselves to be unique and protected from harm Social clock the culturally preferred timing of social events such as marriage, parenthood, and retirement Emerging adulthood a period from about age 18 to the mid-twenties, when many in Western cultures are no longer adolescents but have not yet achieved full independence as adults Stage theory of psychosocial development Erikson's theory; 8 stages with distinct conflicts between two opposing states that shape personality Trust vs. mistrust Refers to a stage of development from birth to approximately 18 months of age, during which infants gain trust of their parents or caregivers if their world is planned, organized, and routine. Autonomy vs. Shame and Doubt Erikson's stage in which a toddler learns to exercise will and to do things independently; failure to do so causes shame and doubt Initiative v. guilt 3rd stage in Erikson's model; preschoolers must learn to start and direct creative tasks, or they may feel guilty about asserting themselves Industry v. Inferiority 4th stage in Erikson's model; children must master the skills valued by their society or feel inferior Identity v. role confusion 5th stage in Erikson's model; adolescents must develop a sense of identity or suffer lack of direction Intimacy v. isolation 6th stage in Erikson's model; young adults must form close, satisfying relationships or suffer loneliness Generativity vs. Stagnation Erikson's 7th stage of social development in which middle-aged people begin to devote themselves more to fulfilling one's potential and doing public service Integrity v. despair 8th stage in Erikson's model; when reflecting at the end of life, an older adult must feel a sense of satisfaction or experience despair (feelings of having wasted one's life) Adverse Childhood Experiences (ACEs) Stressful or traumatic experiences, including abuse, neglect, and a range of household dysfunction, such as witnessing domestic violence or growing up with substance abuse, mental disorders, parental discord, or crime in the home. Achievement (adolescent development) Stage of adolescent identity development that occurs when identity commitments are made after a period of exploration. Diffusion (adolescent development) Stage of adolescent identity development where no commitments are made to identity Foreclosure (adolescent development) Stage of adolescent identity development where commitments are made to identity without first an exploration Moratorium (adolescent development) Stage of adolescent identity development where they are actively engaged in identity exploration racial and ethnic identity the sense of membership in a racial or ethnic group and the feelings that are associated with that membership Sexual orientation an enduring sexual attraction toward members of either one's own sex (homosexual orientation) or the other sex (heterosexual orientation) Religious identity a sense of belonging to a religious group Occupational identity Occupations that we engage in define who we are Familial identity the sense of self as always connected to family and others Possible selves images of what we dream of or dread becoming in the future Behavioral perspective An approach to the study of psychology that focuses on the role of learning in explaining observable behavior. Classical conditioning a type of learning in which one learns to link two or more stimuli and anticipate events Association any connection between thoughts, feelings, or experiences that leads one to recall another Acquisition In classical conditioning, the initial stage, when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response. In operant conditioning, the strengthening of a reinforced response. Associative learning learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequences (as in operant conditioning). Unconditioned stimulus (US) in classical conditioning, a stimulus that naturally and automatically triggers a response. Unconditioned response (UR) In classical conditioning, the unlearned, naturally occurring response to the unconditioned stimulus (US), such as salivation when food is in the mouth. Conditioned response (CR) in classical conditioning, the learned response to a previously neutral (but now conditioned) stimulus (CS) Conditioned Stimulus (CS) in classical conditioning, an originally irrelevant stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response Extinction the diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus (CS); occurs in operant conditioning when a response is no longer reinforced. Spontaneous recovery the reappearance, after a pause, of an extinguished conditioned response Stimulus discrimination a differentiation between two similar stimuli when only one of them is consistently associated with the unconditioned stimulus stimulus generalization learning that occurs when stimuli that are similar but not identical to the conditioned stimulus produce the conditioned response Higher-order conditioning a procedure in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus. For example, an animal that has learned that a tone predicts food might then learn that a light predicts the tone and begin responding to the light alone. (Also called second-order conditioning.) Counterconditioning a behavior therapy procedure that uses classical conditioning to evoke new responses to stimuli that are triggering unwanted behaviors; includes exposure therapies and aversive conditioning Taste aversion a type of classical conditioning in which a previously desirable or neutral food comes to be perceived as repugnant because it is associated with negative stimulation One-trial conditioning when one pairing of CS and a US produces considerable learning Habituation decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a visual stimulus, their interest wanes and they look away sooner. Operant conditioning a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher Reinforcement in operant conditioning, any event that strengthens the behavior it follows Punishment an event that decreases the behavior that it follows Law of effect Thorndike's principle that behaviors followed by favorable consequences become more likely, and that behaviors followed by unfavorable consequences become less likely Positive reinforcement Increasing behaviors by presenting positive stimuli, such as food.Any stimulus that, when presented after a response, strengthens the response. Negative reinforcement Increasing behaviors by stopping or reducing negative stimuli, such as shock. Any stimulus that, when removed after a response, strengthens the response. (Note: negative reinforcement is not punishment.) Primary reinforcers Events that are inherently reinforcing because they satisfy biological needs Secondary reinforcers learned reinforcers, such as money, that develop their reinforcing properties because of their association with primary reinforcers Shaping an operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior Instinctive drift the tendency of learned behavior to gradually revert to biologically predisposed patterns Superstitious behavior a behavior repeated because it seems to produce reinforcement, even though it is actually unnecessary Learned helplessness the hopelessness and passive resignation an animal or human learns when unable to avoid repeated aversive events Reinforcement schedule a pattern that defines how often a desired response will be reinforced fixed interval reinforcement A form of partial reinforcement where rewards are provided after a specific time interval has passed after a response Fixed ratio reinforcement reinforces a response only after a specified number of responses Variable ratio reinforcement A form of partial reinforcement where rewards are provided after an unpredictable number of responses Scalloped graph The graphed pattern of a fixed interval reinforcement schedule Social learning theory the theory that we learn social behavior by observing and imitating and by being rewarded or punished Vicarious conditioning classical conditioning of a reflex response or emotion by watching the reaction of another person Modeling learning by imitating others; copying behavior Insight learning The process of learning how to solve a problem or do something new by applying what is already known Latent learning learning that occurs but is not apparent until there is an incentive to demonstrate it Cognitive maps An internal representation of the spatial relationships between objects in an animal's surroundings.
