Marla hides ramy’s favorite toy under a blanket while ramy watches. ramy removes the blanket and squeals when he sees the toy. marla again hides the toy, but this time under a different blanket. even though ramy saw where marla hid his toy, he still looks under the first blanket and not the second one. ramy has displayed:
a. the a-not-b error correctb. habituationc. lack of object permanenced. lack of centration

The correct answer is A. the A-not-B error

Explanation:

This error, displayed mostly in 8-months-old to 12-months-old infants, was studied by the psychologist Jean Piaget, he explained that the error happens when the child is not able to locate the object in the second location and is still trying to find it in the first location, exactly what happened with Ramy in the task described. The lack of ability to find the object in the location B (in this case the second blanket) is due to the child's lack of object permanence, it means his capacity to percieve the toy even when it is hidden. However, other researchers have suggested  that this error can be caused by  limitations in the short-term memory or the tendency to repeat motor behaviors.

because each is self-sufficient.  

the addition that would strengthen melissa’s thesis statement, both the dark game and the code book explain the importance of codebreaking, is :

main ideas of each book

melissa should discuss the main ideas of each book because these ideas will fully support her thesis statement. through these details, readers will also understand the importance of codebreaking that melissa referred to, which was inspired by the books.
