development

The pattern of movement or change that begins at conception and continues through the life span. Most development involves growth, although it also includes decline brought on by aging and dying.

original sin

Based on the Christian Doctrine, the view that children are born into the world corrupted, with the inclination toward evil.

tabula rasa

The idea, proposed by John Lock, that children are like a "blank tablet".

innate goodness

French philosopher Jean-Jacques Rousseau's idea that children are inherently good.

life-span perspective

The perspective that development is lifelong; multidimensional; and contextual; and involves growth, maintenance, and regulation.

normative age-graded influences

Biological, sociocultural, and environmental influences that re similar for individuals in a particular age group.

normative history-graded influences

Influences that are common to people of a particular generation because of historical circumstances.

cognitive processes

Changes in an individual's thought, intelligence, and language.

socio-emotional processes

Changes in an individual's relationships with other people, emotions, and personality.

chronological age

The number of years that have elapsed since birth.

psychological age

An individual's adaptive capacities compared with those of other individuals of the same chronological age.

social age

Social roles and expectations related to a person's age.
