Sensorimotor Intelligence
Piaget’s term for the way infants think—by using their senses and motor skills—during the first period of cognitive development.
Deferred Imitation
A sequence in which an infant first perceives something done by someone else and then performs the same action hours or even days later.
Object Permanence
The realization that objects (including people) still exist when they can no longer be seen, touched, or heard.
Primary Circular Reaction
feed-back loop involving the infant’s own body. The infant senses motion, sucking, noise, and other stimuli and tries to understand them.
secondary circular reactions
feed-back loop involving people and objects. Infants respond to other people, to toys, and to any other object they can touch or move.
tertiary circular reactions
feed-back loop involving active exploration and experimentation. Infants explore a range of new activities, varying their responses as a way of learning about the world.
The process of becoming accustomed to an object or event through repeated exposure to it, and thus becoming less interested in it.
Visual Cliff
An experimental apparatus that gives the illusion of a sudden drop-off between one horizontal surface and another.
Information processing
Modeled on computer
Involves incremental details and step-by-step description of the
mechanisms of thought
Infantile Amnesia
the belief that infants remember nothing until about age 2
Moblie Experiment
experiment that disproved infantile amnesia, by having infants move a mobile the same way. Thus proving they remebered each time they did so.
Implicit Memory
Unconscious or automatic memory that is usually stored via habits, emotional responses, routine procedures, and various sensations.
Explicit Memory
Memory that is easy to retrieve on demand (as in a specific test). Most involves consciously learned words, data, and concepts.
Universal Sequence (Also called baby talk or motherese.)
The high-pitched, simplified, and repetitive way adults speak to infants and children.
Child-driected speech (Baby talk/motherese)
The high-pitched, simplified, and repetitive way adults speak to infants and children.
Theory says all learning is acquired, step-by-step, through association and reinforcement.
Social Pragmatic Theory
According to this theory, infants communicate because humans are social beings, dependent on one another for survival and joy. It is the emotional messages of speech, not the words, that propel communication.
Language Acquisition Device (LAD)
Chomsky’s term for a hypothesized mental structure that enables humans to learn language, including the basic aspects of grammar, vocabulary, and intonation.
