psychology 4 Flashcards
a branch of psychology that studies physical, cognitive, and social change throughout the life span.
developmental psychology
the fertilized egg; it enters a 2-week period of rapid cell division and develops into an embryo.
zygote
the developing human organism from 9 weeks after conception to birth.
fetus
(literally, “monster maker”) agents, such as toxins, chemicals, and viruses, that can reach the embryo or fetus during prenatal development and cause harm.
teratogens
physical and cognitive abnormalities in children caused by a pregnant woman’s heavy drinking. In severe cases, symptoms include noticeable facial misproportions.
fetal alcohol syndrome
decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a visual stimulus, their interest wanes and they look away sooner.
habituation
biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience.
maturation
an optimal period early in the life of an organism when exposure to certain stimuli or experiences produces normal developement
critical period
all the mental activities associated with thinking, knowing, remembering, and communicating.
congnition
a concept or framework that organizes and interprets information.
schema
interpreting our new experiences in terms of our existing schemas
assimilation
1) In developmental psychology, adapting our current understandings (schemas) to incorporate new information. 2) in sensation and perception, the process by which the eye’s lens changes shape to focus near or far objects on the retina.
accommodation
in Piaget’s theory, the stage (from birth to about 2 years of age) during which infants known the world mostly in terms of their sensory impressions and motor activities.
sensorimotor stage
the awareness that things ontinue to exist even when not percieved.
object permanence
in Piaget’s theory, the stage (from about 2 to about 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.
preoperational stage
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.
conservation
in Piaget’s theory, the preoperational child’s difficulty taking another’s point of view.
egocentrism
people’s ideas about their own and others’ mental states- about their feelings, perceptions, and thoughts, and the behaviors these might predict.
theory of mind
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.
concrete 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.
formal operational stage
a disorder that appears in childhood and is marked by deficient communication, social interaction, and understanding of others’ states of mind.
autism
the fear of strangers that infants commonly display, beginning by about 8 months of age.
stranger anxiety
an emotional tie with another person; shown in young children by their seeking closeness to the caregiver and showing distress on separation.
attachment
the process by which certain animals form attachments during a critical period very early in life.
imprinting
