When adults are working with young children, they often provide a lot of hints, assistance, instructions, and other support to help the children succeed. As the children demonstrate they can do more for themselves, the adults begin to withdraw these supports. This technique is called:

Scaffolding

Explanation:

Scaffolding is a concept that can be found within the zone of proximal development, a theory developed by Vygotsky. Although indeed, the scaffolding was not developed by the same author but by Brunner, this is evident during the child's learning process.

The scaffolding consists of providing the necessary aids that the child needs according to the learning process in which he finds himself and they are being withdrawn according to the progress he is having. In the zone of proximal development, it is understood that each child does not learn in the same way, so the aid provided must be under the educational needs that they present.

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.
