academic self-concept
one of two divisions of children's general self-concept, referring to sense of self as an achiever in school subjects. Can be further divided into specific school subject areas sucha s math, science, English, and social studies
acceptance
A reaction to impending death that is characterized by a sense of peace and relative tranquility, suggesting that one has come to terms with the inevitable.
acceptance factor
An aspect of parental responsiveness that includes being affectionate, praising the child, being involved in the child's life, and showing concern for the child's needs; correlated with children's self-esteem and social adjustment.
accommodation
In Piaget's theory of cognitive development, the adaptation process by which existing knowledge structures are modified somewhat when an individual is exposed to new information
achievement
One of Marcia's four identy status categories characterizing individuals whose development has been marked by exploration and then commitment to certain alternatives. Persons in this category have constructed their identity by their own efforts to shape and transform their earlier selves.
achieving commitment
An alternative name for Marcia's "achievement" that is used by Meeus and colleagues, because it emphasizes the dynamic linkage between high levels of commitment and high levels of exploration.
achieving stage
In Schaie's theory, the stage of cognitive development when a young adult must apply her intellectual skills to the achievement of long-term goals, carefully attending to the consequences of the problem-solving process.
acquisition stage
In Schaie's theory, the time in cognitive development (during childhood and adolescence) when an individual is sheltered from the majority of life's responsibilities and can learn a skill or a body of knowledge regardless of whether it has any practical goal or social implications.
active euthanasia
Injection of a medication by someone else that causes immediate death.
active gene effects
the influence of genes on an individual's choice of environments, companions, and activities. People choose environments that are compatible with their interests, and those interests may be influenced by genes.
activity level
The intensity and quantity of movement an individual displays; one aspect of infant temperament.
actuarial prediction
Predicting an individual's outcome based on group characteristics, such as predicting how likely an individual is to suffer a heart attack based on the frequency of heart attacks in large samples of people with similar characteristics (same age, gender, socio-economic status, etc.)
adaptation
In Piaget's theory of cognitive development, the process by which the human mind constructs its knowledge, both assimilating new information to existing knowledge structures or understandings, and accommodating those structures to create a better fit to what is new.
adolescence-limited antisocial pattern
A developmental pattern of adolescent antisocial behavior that develops in adolescence and usually ends shortly thereafter.
adolescent growth spurt
Corresponding with puberty, a rapid increase in size accompanied by changes in the shape and proportions of the body.
adolescent-onset or late-starter model
A developmental pathway of antisocial behavior that begins in adolescence and is not likely to result in adult criminality. Although serious, it seems to be reflective of a difficult or exaggerated reaction to the adolescent period.

Adult Attachment Inventory (AAI)
A structured interview in which adults describe their memories of the parenting they received and their evaluation of whether and how that parenting influenced their own development. Based on coding of the verbatim transcripts, adults are categorized as having one of four attachment styles: autonomous (secure), dismissing (insecure), preoccupied (insecure), and unresolved (insecure). The security of an adult's attachment style tends to be correlated with the attachment security of their own infants.

allostatic load
The physiological wear and tear on the body that results from ongoing adaptive efforts to maintain stability (homeostasis) in response to stressors.
Alzheimer's disease (AD)
A brain disease that leads to dementia. Becomes more prevalent with age. Extensive brain changes including the development of plaques and tangles lead to the common symptom characteristics of the disease including absentmindedness, confusion, language and memory problems, disorientation, and problems with physical coordination. The eventual outcome is death.
amniocentesis
A medical procedure that can be done during a woman's pregnancy, usually at about the 16th week. A small amount of amniotic fluid is extracted from the uterus with a special syringe.

anal personality
In Freud's personality theory, a person who has an anal fixation.
anal stage
In Freud's theory, the second of psychosexual stage, beginning in the 2nd year of life, when the anal area of the body becomes the focus of greatest pleasure. During this stage, parenting practices associated with toilet training that are either overcontrolling or overindulgent could have long-lasting effects on personality development.

Male hormones, produced in the testes that contribute to the develpment of male reproductive organs and may affect some aspects of brain development.
anger
A type of coping mechanism experienced by one nearing death that is a normal reaction to separation and loss. May be directed toward God, toward others, or toward the disease itself.

A disorder characterized by antisocial behavior, with conduct problems typically beginning in early childhood.
anxious-ambivalent
An attachment category describing babies who show a great deal of distress on separation from their mothers, and who may act angry when reunited with the mother, alternately approaching and resisting her, or who may respond listlessly to her efforts to comfort. They seem preoccupied with their mothers and rarely return to exploration after a separation.
anxious arousal
A state that children are thought to experience when parents discipline them. Hoffman proposed that mild forms help a child pay attention to the parent's socialization message, but more intense arousal attracts the child's attention to other concerns, like their own fear.

A part of the cortex that is not a "primary" area involved in vision, hearing, sensory, or motor functions. Integrates information coming from the various primary cortical areas and appears to be important for complex cognitive functioning.
attachment theory
According to Bowlby, the infant and his primary caregiver(s) participate in an interactive system that has evolved to keep the infant safe and ensure survival. As the infant changes cognitively and emotionally, an affectional bond with the caregiver emerges in stages, with a full-fledged attachment likely by about 7 or 8 months.

attention-persistence
Length of uninterrupted orienting or attention to a single activity and tendency to return to a task after interruption; an aspect of infant temperament.
attribute substitution
A process involving imitation and identification in which adolescents need to borrow and "try on" various behaviors and attributes that they observe in others, because the state of frameworklessness leaves them without clearly defined ways of behaving and thinking.
authoritarian style
An interactive parenting style that combines low levels of warmth (cold emotional climate) with high levels of control of demandingness. Associated with negative emotional tone, poor social skills, and other negative outcomes in children.

autonomous stage
Stage of moral development described by Piaget that begins in middle childhood. Children now understand that rules are based on social agreements and can be changed.
autonomy
In Ryan and Deci's self-determination theory, one of three basic or universal needs. Being in control of oneself, or feeling that one's behavior is congruent with one's "true self", meaning that it is intrinsically motivated.
autonomy versus shame and doubt
The crisis faced in the second of Erikson's "Eight Stages of Man," in which the 1- to 3-year old child may develop feelings of autonomy ("I can do things myself") or of shame and self-doubt, depending on whether his caregive strikes the right balance between exercising control and being sensitive to the child's new need for independence
autosomes
The 22 of 23 pairs of chromosomes in humans that are matched (they look and function alike).
average
A sociometric category that includes those children who receive an average number of positive and negative nominations from their peers (near the mean for the group on social preference and social impact).
avoidant
An attachment category describing babies who typically fail to cry when separated from their mothers in a strange situation test. They actively avoid or ignore her when she returns, sometimes combining proximity seeking and moving away, but mostly turning away and often appearing unemotional. In Bartholomew's typology of adult attachments, a category that is subdivided into two types (dismissing and fearful) based on the individual's reports of felt distress.
axon
A long extension, projecting from the cell body of a neuron, which is like a cable attached to a piece of electronic equipment. Electrical impulses travel from the cell body through the axon toward synapses with other neurons.
axon terminals
Structure found at the ends of axons, which contain tiny sacs of neuro-transmitters.
babbling
Infant vocal sounds, usually beginning around 6 months of age, consisting of repeated consonant-vowel-consonant sequences such as "bababa" or "doodoodoo". By 9 months of age, they tend to be limited to the sounds permissible in the baby's native language.
bargaining
A reaction to impending death that serves as an attempt to postpone an inevitable death by making promises, usually to a divine other, or trying to delay death until some memorable event has taken place.
basic trust
In Erikson's theory of personality development, an infant's ability to see others as dependable and trustworthy as a result of care-giving that is timely, sensitive to the infant's needs, and consistently available.
behavioral facilitation system
Neural system that regulates approach behaviors, response to incentives, positive affect, and psychomotor activity.

circuits
Series of neurons that are joined via their synaptic connections into groups and are part of larger organizations of neurons.
classical conditioning
A process by which a change in behavior takes place when a neutral event of stimulus is associated with a stimulus that causes an automatic response. As a result the neutral stimulus causes the person to make the same automatic response in the future.
climacteric
The gradual reduction of reproductive ability in women usually beginning in their late 30s when the menstrual cycle begins to shorten and become somewhat more erratic as a result of a reduction in the amount of circulating estradiol.

closed identity domains
Areas of identity in which individuals tend toward foreclosure because they have little control over them.
coaction
The intricate pattern by which genes and environmnet mutually influence one another. The activity of the genes is affected by the environment of the cell that is affected by other levels of the environment including the outside world. One result is that the same complement of genes produces different outcomes in different environments. Also, the same environment can have different effects on outcomes when interacting with different genes.
code switching
Shifting from one form or style of speech to another depending on context, such as shifting from using slang with friends to using more polite forms with authority figures.
codominance
A type of relationship between two alleles of the same gene (located at matching sites on a pair of chromosomes) in which neither allele is suppressed., producing a blended outcome.
coercive family interaction
Patterson's description of how children learn to act aggressively. Aggressive children respond to parental demands by behaving aversively (whining, etc), parents retreat, rewarding the child's noncompliance, and parents are reinforced with short-lived peace and quiet. Children are trained in the effectiveness of aggressive noncompliance and learn powerful parent-control strategies.
cohort
A group of people who were born in the same historical period and grew up at about the same time.

Also called history-graded events, they are events that provide a context for development and also influence it directly. The year of your birth marks your entry into a cohort of peers who accompany you through age-graded developmental changes within the context of a specific set of historical events.
collaborative or affiliative speech
A type of speech, more often used among girls, in which children's responses are keyed to what someone else has said, expressing agreement or making further suggestions, often in the form of a question rather than declarative or imperative sentences.
collective egocentrism
Peer influences on maintaining risky behavior; each adolescent's illusion of invincibility strengthens that of the other members of the peer group.
commitment
An element of love that refers to making a decision to sustain a relationship with a loved one.
commitment foreseen
Position 6 in Perry's model in which thinking incorporates not only respect for diverse ideas and understanding of their rationale, but also the individual's affirmation of what it is she believes in, all the while knowing that reason will never provide absolute proof that her ideas or perspectives are right or better than others.
committed compliance
Describes toddlers' eager and enthusiastic willingness to go along with parental requests. Predicts measures of internalization and conscience in the later pre-school period.
communion
A constituent of generativity that is expressed in the adult's desire to care for the next generation, even to the point of sacrificing her own well-being for the good of those who will follow.
compatibility
A standard for mate selection in which one chooses a potential mate based on how his or her personality meshes with one's own personality.
compelling circumstances
Conditions that mitigate the guilt of a criminal defendant because he or she faced such pressure when the crime was committed that even an ordinary, reasonable person could be expected to have acted in the same way, such as acting in the face of extreme need or under threat of injury.
compensation
A process that contributes to successful development. When a loss of some kind prevents the use of one means to an end, the individual finds another means.

In self-determination theory, feeling effective in one's interactions with the social environment and experiencing opportunities to exercise and express one's capacities.
complicated or abnormal grief
A response to bereavement that is generally accompanied by other disorders such as major depression, substance abuse, or post-traumatic stress disorder that is intense and lasts for an extended period of time, greatly interfering with functioning. Abnormal grief may also be marked by a complete absence of grief and the total inability to experience grief reactions.
compulsive caregiving
Describes a behavioral pattern in which children (usually insecurely attached, avoidant children) take emotional care of their parents.
compulsive self-sufficiency
Describes a behavioral pattern in which children (usually insecurely attached, avoidant children) appear very self-possessed, perhaps related to experiences of shaming for expressions of dependency or needs for closeness.
concrete operational stage
In Piaget's theory of cognitive development, the period from about age 6 to 12 when children begin to think logically but have difficulty applying logical thought to abstract contents.
conditioned stimulus
A formerly neutral stimulus that has become associated with a stimulus that causes an automatic response, thus causing the same automatic response in the future.
conduct disorder (CD)
A pattern of serious behavior problems that violate the basic rights of others, such as stealing, aggression, or property destruction. Presently, this diagnosis requires a persistent pattern of aggression in youth.
conferred identity
The identity attained by those who are foreclosed (individuals who make commitments with little or no exploration of alternatives).
confirmation bias
When a child's peers have already developed schemas or constructions for him that are built on his social reputation, the interactions with the target child that follow are marked by attention to evidence that confirms the target child's characteristics.
congenital adrenal hyperplasia (CAH)
A gender-atypical condition in which biological females with two X chromosomes are exposed to high levels of androgens (male hormones) during prenatal and postnatal development.
conscience
An internalized slate of standards and principles that constitutes a person's primary guide to action. May cause feelings of discomfort or distress when the violation of a rule is contemplated or carried out.

consolidation
In Super's theory, achievement of advanced status and seniority in the work-place that often accompanies the maintenance stage.
constructed identity
The identity not based upon a predetermined set of expectations, but rather representative either of a personal redefinition of childhood and early adolescent goals and values or perhaps something very different from them.
constructivism
Rooted in theories such as Piaget's, assumes that individuals are not just passive receptors of information who acquire knowledge via external manipulations. Instead, people actively construct their knowledge by interpreting information in light of prior learning, by actively restructuring prior knowledge, or by co-constructing knowledge in interactions with others.
contextual relativism
Position 5 in Perry's model that represents a major achievement in intellectual development because the student now possesses analytic abilities that allow her to appreciate the merits of diverse perspectives and to find convincing elements in multiple points of view. Thinking relativistically, or thinking about knowledge in context, becomes more habitual.
contingency management system
Presenting and withdrawing reinforcers and punishments in a systematic and consistent way to effect behavioral change.
control dimension (parental demandingness)
One of two major features of parenting style. The degree to which parents impose discipline, requiring their children to curb some of their behaviors and to perform other behaviors that are suitable to their level of maturity.

controversial
A sociometric category that identifies a relatively small group of children who receive many positive and many negative nominations from peers (high social impact, average social preference).
conventional morality
Kohlberg's second stage of moral reasoning in which what is right depends on others' approval or on the need to maintain social order.
conventional rules
Social rules of conduct that vary from one culture to another and are a function of social agreement, such as rules about appropriate dress, forms of address, and table manners.
cooperative learning environments
Classrooms or other organizations that encourage children to work in pairs or in groups to solve academic problems and to improve their understanding of concepts or skills.
corpus callosum
A network of fibers that connects the right and left cerebral hemispheres of the brain. Its maturation from early childhood through adolescence contributes to coordination and integration of information and aids in the development of consciousness.
correlational studies
Often utilized when experiments are impractical or unethical, a technique in which both the causal variable and outcome variable are measured or observed, and nothing is actually manipulated by the researcher. Such studies can determine whether changes in the causal variable are matched by predicted changes in the outcome variable, but they cannot determine whether changes in the causal variable caused the changes in the outcome variable.
corticotrophin releasing hormone (CRF)
A hormone produced by the hypothalamus that stimulates the pituitary gland to release adrenocorticotrophic hormone (ACTH).
cortisol
A hormone, released during the body's response to stress, that increases blood glucose levels and affects the immune response.

developmental psychopathology
A relatively new and influential field that has applied a developmental focus to the study of abnormal behavior and dysfunction.
diathesis
Underlying predispositions to some disease or abnormal condition.
diathesis-stress
Model for the development of psychopathology that assumes a genetic predisposition (diathesis) that confers particular sensitivity to environmental risk (stress).

Izard's view that facial expressions in infants are the direct manifestation of underlying neural processes related to the emotion expressed. For example, a sad expression implies the operation of the neural circuitry associated with sadness, so that if a baby looks sad, he is sad.
differential susceptibility
Child temperament moderates the influence of parenting styles and disciplinary strategies.
differentiation
The process by which a global skill or activity divides into multiple skills or begins to serve multiple functions.
difficult babies
A temperament type described by Thomas and Chess. These babies are fearful, irritable, active, display low levels of positive affect, are irregular in biological rhythms, and so on, making them more challenging to care for than other babies.
diffusion
One of Marcia's four identity status categories that often describes young adolescents as they embark on the identity development process. The individual is not actively involved in exploring possible life choices, nor has she made any firm commitments to them.
digit span tests
A test of working memory in which a series of digits are presented and the participant must repeat them in the correct order.

One source of mitigation in adult criminal law. A guilty actor is considered less than fully blameworthy because of some deficiency at the time of the offense. Perhaps he was mentally ill, emotionally distressed, or intellectually impaired.
discipline
The tendency of parents to limit or demand behavior by exerting or requiring control.
disenchantment
The second stage of retirement, when people begin to experience an emotional "letdown" as they face the day-to-day realities of the change, such as separation from work colleagues, uncertainties about how to feel competent and in control, a sense of diminished generativity and meaningfulness, new tensions that may arise with one's partner, financial concerns, and perhaps, boredom.
dishabituation
After habituating to one stimulus, an infant may show reinstatement of the orienting response if the stimulus is changed. This response is dishabituation and indicates that the baby has noticed the difference between the original stimulus and the new stimulus.
disillusionment model
The view that posits that overly romantic idealizations of marriage and blissfully optimistic views of one's partner set people up for eventual disappointment.
dismissing (insecure)
An attachment style characterizing adults whose Adult Attachment Inventory transcripts provide little detail and coherence. They may describe their parents positively but provide either no evidence or contradictory evidence. They downplay close relationships and tend to have children who are in the avoidant attachment category. In Bartholomew's typology, these individuals prefer self-sufficiency and maintain a sense of superiority while devaluing the importance of others to their well-being.
dismissive parenting
Also called neglecting, a parenting style that describes parents who are essentially disengaged, scoring low on both responsiveness and demandingness.
disorganized-disoriented
An attachment category describing babies who produce contradictory and even bizarre behaviors in the strange situation test, showing both an inclination to approach the mother when stressed and a tendency to avoid her when she approaches.
distal processes
Factors outside the immediate external environment, including internal forces (genes) and external forces (features of the educational system or of the broader culture), which modify the proximal processes in Bronfenbrenner's bioecological model and other multidimensional theories.
distraction

Position 9, although placed at the end of the line, does not imply a static resolution of existential conflict; rather, it characterizes a state of courageous resolve to continue the work of reflecting on one's commitments throughout adulthood.
responsible stage
In Schaie's theory, the stage of cognitive development faced during middle adulthood in which ill-defined problems remain the norm, but problem solving must now take into account not only one's own personal needs and goals but also those of others in one's life that have become one's responsibility (spouse, children, coworkers, member of the community).
