1.Do axons and dendrites meet at synapses? True
2. Does perception take place in the corpus callosum? False
3. One of the drawbacks of breast feeding is that the quantity of breast milk produced is not adjustable. for example it may be difficult for a mother to keep up with the demands of twins. False
4. Among the first acquired adaptations is accomodation of reflexes. For example the reflexes involved in sucking a pacifier? True
5. Reminder sessions can prolong young infants memory of earlier events? True
6. By about 30 months of age, toddlers can remember and re-enact complete sequences of activities they have witness? False
7. Preverbal infants show a preference for baby talk over ordinary adult speech? True
8. Deaf babies do not babble? False
1. Synapse is a gap, so you have to define what you mean by "meet."
2. Right.
3. Agree.
4. Is suckling acquired or inborn?
5. I'm not sure what you mean by reminder sessions. However, events need to be repeated often to be remembered. Also, in later life, there is no evidence of conscious memory of pre-language events.
6. Don't know about this one. Consult your text. It would depend on the complexity of the sequence.
7. How are you defining "preverbal"?
8. I would agree.
Sorry that I cannot provide exact answers for some of your questions.
1. Yes, axons and dendrites do meet at synapses. Axons are long, slender projections of a nerve cell that transmit electrical signals away from the cell body, while dendrites are shorter, branch-like extensions that receive signals from other neurons. At synapses, the axon terminal of one neuron passes signals to the dendrite of another neuron, allowing for communication between neurons.
2. No, perception does not take place in the corpus callosum. The corpus callosum is a bundle of nerve fibers that connects the left and right hemispheres of the brain, enabling communication between them. Perception, which refers to the organization and interpretation of sensory information, takes place in various parts of the brain, including the sensory areas and association areas.
3. No, it is not true that the quantity of breast milk produced is not adjustable during breastfeeding. The quantity of breast milk produced can vary based on the baby's demand and the mother's breastfeeding practices. Mothers can increase their milk supply by nursing frequently, ensuring proper hydration and nutrition, and using techniques like breast compression. In the case of twins, there may be a higher demand for milk, but mothers can still produce enough milk for both babies through proper breastfeeding techniques and support.
4. Yes, one of the first acquired adaptations in infants is the accommodation of reflexes, including the reflexes involved in sucking a pacifier. Infants are born with basic reflexes, such as the rooting and sucking reflexes, which aid in feeding. Over time, they learn to coordinate these reflexes and adapt them to different situations, such as sucking on a pacifier for comfort.
5. Yes, reminder sessions can prolong young infants' memory of earlier events. Research has shown that infants' memories can be strengthened through repeated exposure to the same information or events. By reminding them of previous experiences, infants are more likely to retain and recall the information for a longer period of time.
6. No, it is not true that toddlers can remember and re-enact complete sequences of activities they have witnessed by about 30 months of age. While toddlers are capable of remembering and imitating simple actions and behaviors, their ability to remember and reproduce complete sequences of activities may still be limited at this age. It takes time for their cognitive and memory skills to develop fully.
7. Yes, preverbal infants often show a preference for baby talk over ordinary adult speech. Baby talk, also known as infant-directed speech or "motherese," is characterized by exaggerated pitch, rhythm, and repetition. Infants are more attracted to this type of speech as it captures their attention and helps in language development by highlighting important aspects of language, promoting social interaction, and facilitating language learning.
8. No, it is not true that deaf babies do not babble. Babbling is a natural and universal stage of language development in which infants produce repetitive strings of sounds, such as "ba-ba" or "ma-ma." Deaf babies may babble differently from hearing babies, as their vocalizations may not include recognizable speech sounds, but they still engage in vocalizations and explore their vocal capabilities. In fact, research has shown that deaf babies can babble with their hands, using sign language instead of vocalizations.
