Answer:
The correct answer is The study has a problem with the External validity
Explanation:
External validity in research terms is the validity the research has in the outside world or in the applied social reality of the field of study, it is the extent in which the results and conclusions of the study can be applied and generalized to ohter external factors, therefore in this case, when the researchers did the experiment only with motivated volunteers did not take into account that people outside may not have the same motivation, therefore the results may not be the same in the external social reality and thus having problems with the external validity.
I believe the right answer is social interaction.
Lev Vygotsky's theories stress the fundamental role of social interaction in the development of cognition (Vygotsky, 1978), as he believed strongly that community plays a central role in the process of "making meaning."
Vygotsky’s main assertion was that children are entrenched in different sociocultural contexts and their cognitive development is advanced through social interaction with more skilled individuals. Vygotsky (1978) states: “Every function in the child’s cultural development appears twice: first, on the social level, and later, on the individual level; first, between people (interpsychological) and then inside the child (intrapsychological). This applies equally to voluntary attention, to logical memory, and to the formation of concepts. All the higher functions originate as actual relationships between individuals.” (p57).
