Answer:
Exceptional children
Explanation:
In psychology and education, we use the term "exceptional children" to refer to children who differ from the norm (either being above the norm or below it). This deviations can occur in mental, emotional, physical or emotional aspects and the deviations occur in such an extent that they need specialized education services. 
Therefore, we can say that Individuals who deviate from the norm to such an extent that special educational services are required are called exceptional children. 
 
        
             
        
        
        
Answer:
To avoid the ethical issues a true experiment would cause.
Explanation:
A quasi-experiment is a factual conventional study that is used to calculate the causal effect of interference on a target population without an irregular function. Quasi-experimental research shares closeness with traditional experimental design or randomized controlled trials, but lacks the element of random assignment specifically for treatment or control. 
Instead, quasi-experimental designs typically allow the researcher to control the assignment to treatment status, but use some criterion other than random assignment (For example- an eligibility cutoff mark).
 
        
             
        
        
        
Crystal's behavior in looking up information in books, newspapers, dictionaries, and the Internet, illustrates the need for understanding and self-realization of Maslow's need hierarchy.
<h3 /><h3>What do you understand by Maslow's need hierarchy?</h3>
The Maslow sequence can be defined as a set of basic human needs in order for a person to achieve complete development and to make themselves real.
 When we compare this crystal behavior with Maslow's need hierarchy requirements, it states that the need for understanding and self-realization must be met by Crystal.
Thus, Crystal's attitude toward looking at information in books, newspapers, dictionaries, and the Internet reveals the need for understanding and self-realization of Maslow's need hierarchy
