Answer:
Behavioral Perspective
Explanation:
The fact that "small changes are introduced in the child's environment" can be taken as a good example of behavioral perspective since the ones that work with this idea consider that evironment has an important influence in behavior. They have the conception that when interacting with a given environment an individual can develop certain attitudes and responses.
Deciding whether a study will compare different groups of individuals or examine changes within the same group of individuals involves a decision about the research <u>des</u>ign.
Explanation:
Behavioral research studies about patterns and their variables of individual and social behavior of a person with response to stimuli (internal or external)
A research design essentially is the blueprint of the research that integrates and interlinks various research components like evidence and data collection, measurements undertaken, analysis and the interpretations made in a coherent, logical and comprehensive way.
Decision about the type of comparison group in group experimental researches is taken during research design to decide about how the comparison should be made to obtain the correct results. It can be compared with an individual to a group, or a control group against an experimental group.
The pattern changes in each group is studied based on the independent variables which changes in the experimental group and is fixed or constant in a control group.
I believe the answer to this question is C.
