Cephalocaudal growing > Growing from head to toe (infant)
Proximodistal growing > Growing from near to far
Term
Heterochroncity
Definition
Different rates of growth for different bodily systems
Term
Canalization
Definition
Return to expected path after moderate disruptions
Term

If you place your fingers in a baby's hand, they'll grab it. Occurs from birth to 5 months.
Term
Rooting Reflex

Term
How can the dynamic systems approach be used to understand motor development?
Definition
Complex motor skills require the assembling and reassembling of multiple processes involving motivation, elements of the nervous system that regulate posture and balance, increased bone and muscle strengh changes in the body. How EVERYTHING intereacts.

How are learning and memory different?
Definition
Information that is store in the learning process is imortant for the memory process. Learning his how you acquire new information about the world and memory is how you store that information over time.
Term
Classical Conditioning
Definition
You learn associations between consistently paired stimuli. You learn positive associations quicker than negative ones.
Term
Operant COnditioning
Definition
Learning is through positive and negative reinforcement and punishment
Term
Statistical Learning
Definition
Emphasizes that associations are formed because of some events expressed within a particular language, co-occur statistically predictable order. In other words, infants and young children can learn from the many kinds of regularities that they experience in their world. It's also about extracting abnormalities. Association and frequency occurs.
Term
Perceptual Learning
Definition
The process of learning improved skills of perception.
Term
Role of Rewards in Learning
Definition
An infant will learn to repeat behaviors that lead to rewards and avoid behaviors that will fail to produce rewards or punishment. Rewards can be variable: nourishment, changed contact, attention, smiles, stimulation, motion, etc.
Term
Habituation
Definition
Detecting the ability to discriminate between stimuli. It is measured by the time they take to habituate and distinguish between two stimuli.

Term
Saccades

Term
Lateral Inhibition
Definition
The capacity of an excited neuron to reduce the activity of its neighbors. Lateral inhibition sharpens the spatial profile of excitation in response to a localized stimulus,.
Term
Externality Effect
Definition
The tendncey for younger infants than 2 months to focus on external features of a complex stimulus. Older infants focus on the internal features.
Term
Intermodal Perception
Definition

A large sheet of glass bisected by wood. Used to test depth perception.
Term
Theory of Core Knowledge
Definition
Children come equipped with domain specific theories, which allow them to break into laerning within that domain. FOr example, young infants appear to be sensitive to some predictable regulatities in the movement and interactions of objects.
Term
Theory of Modularity
Definition
The notion that amind may, at least in part, be composed of serperate innate structures, which have established evolutionary developed functional purposes.
Term
Evidence that there is something special about the perception of faces
Definition
-Behavioral Evidence: Inversion effects: more disruptive for faces(Margaret THatcher). Configural processing: better at whole than parts.

-Clinical Evidence: Prosopagnosia: inability to recognize faces. Anti- Inability to recognize words and objects.
