ABSTRACT
This chapter discusses the McGraw’s famous twin study involving early stimulation and deprivation. David Elkind is a professor, psychologist, and prolific author who observes that many parents are convinced that earlier is better in terms of the training and education of their children. The researchers concluded that infant swimming experiences in chlorinated indoor pools can induce airway changes that lead to chronic respiratory conditions. The effects of early forms of deprivation, or maltreatment, are important to developmentalists studying all aspects of human behavior. The perceived deprivation of institutionalization was found to have a significant impact on motor development. Delays in speech, cognition, and motor development are common, along with withdrawal, apathy, self-injury, irritability, and a tendency toward temper tantrums.
