Psychological essentialism
The belief that members of a category have an unseen property that causes them to be in the category and to have the properties associated with it
Borderline items
Typicality
some items in a category seem to be better members than others
family resemblance theory
Proposed that items are likely to be typical if they have the features that are frequent in the category and do not have the features in other categories
(robins vs penguins - robins are more typical birds than penguins)
Sensorimotor stage
Preoperational reasoning stage
Concrete operations stage
formal operational stage
Continuous development
Ways in which development occurs in a gradual incremental manner, rather than through sudden jumps
Depth perception
The ability to actively perceive the distance from oneself of objects in the environment
Discontinuous development
Development that does not occur in a gradual incremental manner
Information processing theories

Numerical magnitudes
The sizes of numbers
Nurture
Object permanence task
Phonemic awareness
Awareness of the component sounds within words
Piaget’s theory
Theory that development occurs through a sequence of discontinuous stages: the sensorimotor, preoperational, concrete operational, and formal operational stages
Qualitative changes
Large, fundamental change (as when a caterpillar changes into a butterfly)
Quantitative changes
Gradual, incremental change, as in the growth of a pine tree’s girth
