sandra has learned to squeeze her stuffed bear to make it squeak. when her father gives her a new stuffed toy, she squeezes it the same way she squeezes the bear. here, sandras action is an example of
select one:
o a. primary circular reactions.
o b. coordination of secondary schemes.
o c. secondary circular reactions.
o d. primary reflexes.

Explanation:

For question 24:

• Piaget's sensorimotor stage has sub - stages. Secondary circular reactions (4 - 8 months) involve repeating actions that have interesting consequences in the external world. Gina pulling the cord (an external object) repeatedly because it makes the jumping jack move is characteristic of secondary circular reactions.
• Coordination of secondary schemes (8 - 12 months) involves combining two or more actions to achieve a goal. Primary circular reactions (1 - 4 months) are centered around the baby's own body. Tertiary circular reactions (12 - 18 months) involve experimenting with different actions to see different results.

For question 25:

• Coordination of secondary schemes (8 - 12 months) is about using a previously learned action (squeezing) on a new object (new stuffed toy) to achieve a similar result (making it squeak, assuming the new toy can squeak).
• Primary circular reactions are body - centered. Secondary circular reactions are about repeating actions on external objects but not necessarily generalizing to new objects in the way described. Primary reflexes are innate, unlearned responses.

Answer:

1. B. secondary circular reactions
2. B. coordination of secondary schemes
