Chapter 4: Review T/F Growth is slow and steady throughout infancy and toddlerhood. T/F Lateralization refers to the fact that the two sides (hemispheres) of the brain operate separately, with one side responsible for creativity and the other for analytical thought. Refer to the diagram on the right. What are neurons? What are synapses? What are glial cells? What do you think? In The Human Baby – To Talk, we learned that gazing and mutual attention are necessary for babies to learn language. Does modern technology compromise the development of babies?

Chapter 5 Review: Piaget Identify each sensorimotor substage ______  Infants’ primary means of adapting to the environment is through reflexes. ______  Infants engage in goal-directed behavior and begin to attain object permanence ______  Toddlers explore properties of objects by acting on them in novel ways and begin to imitate unfamiliar behaviors. ______  Infants display simple motor habits centered on their own body with limited anticipation of events. ______  Infants’ actions are aimed at repeating interesting effects in the environment and imitation of familiar behaviors. ______  Toddlers gain the ability to create mental representations and exhibit deferred imitation and make-believe play.

Chapter 5: Information Processing Match each part of the mental system with its description, according to the information-processing approach. _______ Sensory register _______ Working, or short- term, memory _______ Long-term memory A. Represents sights and sounds directly; stores information briefly and monitors strategies B. Permanent knowledge base C. Where we actively apply mental strategies to a limited amount of information ________________, the simplest form of memory, involves indicating whether a new experience is identical or similar to a previous one. ________________, on the other hand, is much more challenging because it involves remembering something not present.

Answers Slide 4: Chapter 4 Review Fals, false neurons are specialized nerve cells in the brain; the “head” of one comes in close contact with the “tail” of another leaving synapses, or small gaps between them; glial cells are the support cells of the brain, with an important purpose is myelination, or coating the neuron axons with a fatty sheath to provide insulation No right answer to the “what do you think” question
