Conversely, this theory does not take into account the free will of an individual. A child may not have stopped bad behavior, but just pretended to, due to the chance they could receive a reward. It also shows that all responses include a reflex, so what is learned is limited. The cognitive theory is also significant. It attempts to explain human behavior by understanding thought processes. It has practical uses in understanding and communicating with children. Because of this, we now recognize the types of thinking that are possible at various ages. It has revolutionized developmental psychology by focusing attention on active mental processes, yet it does not always recognize physical and environmental factors in determining behavior. It is also difficult to prove because thoughts are not observable and are not measurable. Next, is the contextual theory. This looks at the way cognitive processes operate in various settings (Brittanica, 2015). It focuses on the multiple aspects of any learning environment. It relies on the development and growth that occur according to one’s environment and contextual influences. In this approach, a fundamental and practical approach to truth and …show more content…
In school-aged children, a proper balance of nutrients is essential for healthy brain development. Nutrient shortages of iron and iodine impair cognitive and motor development. A deficit of B vitamins, folate, and zinc may affect early brain functioning. Shortages of Omega 3 PUFA’s have been found to correlate with learning and behavioral disorders. Throughout one 's life, malnutrition can cause physical and intellectual impairments. It also can affect the quality and length of an individual’s life. According to the article, “Relatively few studies have examined the effect of…on behavior and development in children” ( Nutrients, 298). Since behavior may be subjective, and qualitative research in nutrition and behavior is harder to measure, due to varying thoughts and opinions; for the purpose of this article, quantitative research was used to measure cognitive development. It takes a systematic approach to measuring data. The researchers delimitations clearly defined the nutrients utilized in the study, and how independently and in combination they affect the development of children after infancy. The study’s limitation suggests the need for future research on combined nutritional effects and micronutrients. Research is also still required to determine the effect nutrition has on the development of a child’s frontal brain
