These flashcards cover critical vocabulary related to perceptual and motor development as discussed in the lecture notes.

Perceptual processes

The means by which people receive, select, modify, and organize stimulation from the world.

Size constancy

The understanding that an object remains the same size even though it appears smaller when it is farther away.

Dynamic systems theory

Attention networks

Systems within the brain that manage focus, orienting, and alertness.

Intermodal perception

The ability to integrate information from different sensory modalities.

Fine-motor skills

The ability to make small, precise movements, often involving the hands and fingers.

Smell, taste, and touch.

Adults have a better sense of _________ than newborns

Hearing and vision

Intersensory redundancy theory

Infants prefer amodal information presented in multiple sensory modes. Prior theories thought infants had only individual sensory capacities.
