child psych

The study of age-related changes in behavior, thinking, emotions, and social relationships.

Average ages at which developmental events happen.

The theoretical view that defines development in terms of behavior changes caused by environmental influences.

Sequential patterns of change that are governed by instructions contained in the genetic code and shared by all members of a species.

Any time period during development when an organism is especially responsive to and learns from a specific type of stimulation. The same stimulation at other points in development has little or not effect.

A period during which particular experiences can best contribute to proper development. It is similar to a critical period, but the effects of deprivation during a sensitive period are not as sever as during a critical period.

The study of the genetic contributions to behavior or traits such as intelligence or personality.

A theoretical concept emphasizing that each child creates a set of core ideas or assumptions about the world, the self, and relationships with others through which all subsequent experience is filtered.

Changes that are common to every member of a species.

Changes that occur in most members of a cohort as a result of factors at work during a specific, well-defined historical period.

A group of individuals who share the same historical experiences at the same times in their lives.

Changes that result from unique, unshared events.

Sets of statements that propose general principles of development.

Developmental theories based on the assumption that age-related change results from maturationally determined conflicts between internal drives and society's demands.

The term used by Freud to describe the basic, unconscious, instinctual sexual energy in each individual.

In Freudian theory, the inborn, primitive portion of the personality, the storehouse of libido, the basic energy that continually pushes for immediate gratification.

In Freudian theory, the portion of the personality that organizes, plans, and keeps the person in touch with reality. Language and thought are both ego functions.

In Freudian theory, the "conscience" part of personality, which contains parental and societal values and attitudes incorporated during childhood.

The stages of personality development suggested by Freud: the oral, anal, phallic, latency, and genital stages.

The stages of personality development suggested by Erikson, involving basic trust, autonomy, initiative, industry, identity, intimacy, generativity, and ego integrity.

Developmental theories that emphasize children's actions on the environment and suggest that age-related changes in reasoning precede and explain changes in other domains.

The term used by Bruner to describe the process by which a teacher (or parent, older child, or other person in the role of teacher) structures a learning encounter with a child, so as to lead the child from step to step - a process consistent with Vygotsky's theory of cognitive development.

In Vygotsky's theory, the range of tasks that are slightly too difficult for a child to do alone but that can be accomplished successfully with guidance from an adult or more experienced child.

A set of theories based on the idea that humans process information in ways that are similar those used in computers.

Psychological theories that explain development in terms of accumulated learning experiences.

One of three major types of learning. An automatic, or unconditional response such as an emotion or a reflex comes to be triggered by a new cue, called the conditional stimulus, after having been paired several times with that stimulus.

The type of learning in which the probability of a person's performing some behavior is increased or decreased because of the consequences it produces.

The process of strengthening a behavior by the presentation of some pleasurable or positive stimulus.

The process of strengthening a behavior by the removal or cessation of an unpleasant stimulus.

The removal of a desirable stimulus or the administration of an unpleasant consequences after some undesired behavior in order to stop the behavior.

The use of multiple theoretical perspectives to explain and study human development.

A testable prediction based on a theory.

A form of research study in which samples of participants from several different age groups are studied at the same time.

A form of research study in which the same participants are observed or assessed repeatedly over a period of months or years.

A form of research study that combines cross-sectional and longitudinal designs in some way.

In-depth studies of individuals.

A research method in which participants are observed in their normal environments.

A statistic used to describe the strength of a relationship between two variables. It can range from +1.00 or -1.00, the stronger the relationship being described.

A research method for testing a causal hypothesis, in which participants are assigned randomly to experimental and control groups and the experimental group is then provided with a particular experience that is expected to alter behavior in some fashion.

A group of participants in an experiment who receive a particular treatment intended to produce some specific effect.

A group of participants an experiment who receive either no special treatment or some neutral treatment.

A condition or event that an experimenter varies in some systematic way in order to observe the impact of that variation on participants' behavior.

The variable in an experiment that is expected to show the impact of manipulations of the independent variables; also called the outcome variable.

Any study that involves comparisons of different cultures or contexts.

A detailed description of a single culture or context based on extensive observation.
