Dr. Stott's belief about that the 9-year-olds will advance in knowledge based on instructions is based on the theory of cognitive development, proposed by Lev Vygotsky.
Explanation:
Theory of cognitive development -also called the socio-cultural theory of cognition- was put forward by the Russian-Jewish psychologist Lev Vygotsky, in which he expresses the influence of the socio-cultural environment on the learning process.
<u>For Vygotsky, children possess innate basic skills, such as attention, sensation, memory and perception, which develop over time</u>.
The process of cognitive development implies that the development of each child's basic skills requires the guidance of an adult, since -although there are skills that he does not understand or has not developed- he can learn them with the appropriate guidance and instructions.
