Unit 004 – Child Development. Section 1. A good introduction should introduce child development with particular attention to ‘holistic’ development and describe expected patterns of development and what this means. Child development is a stage that every child goes through. This process involves learning and mastering skills like sitting‚ walking‚ talking‚ skipping‚ eating and tying shoes. Children learn these skills called developmental milestones during predictable time periods. Children develop

Moreover‚ he noticed that when a dog was presented or introduced to a stimulus such as a ringing bell simultaneously with being fed‚ the dog would begin to salivate when he heard the bell even if food was not present when the bell was rang (Kowalski & Westen‚ 2011‚ Chapter 5). This formed the conclusion‚ that the dog had associated the bell with food‚ and because food produced a reflex of salivation from the dog‚ the bell

Developmental psychology studies the biological‚ cognitive‚ social‚ and personality development that occurs throughout an entire life span (Griggs‚ 2014‚ p. 271). Babies narrows the scope of developmental psychology and places the focus on the infancy stage. The documentary introduces four newborns—as well as the different childrearing norms of each culture—from birth to around 18 months. Two infants are from rural areas: Ponijao is from Opuwo‚ Nambia‚ and Bayar is from Bayanchandmani‚ Mongolia.

he nervous system is the communication network of the body. It consists of a complex collection of nerves and specialized cells‚ called neurons‚ that transmit messages across the different parts of the body in order for it to function and react correctly. They are known as the building blocks of the nervous system. Structurally they have long extensions that extend out from the cell body. There are two types of these extensions; dendrites‚ which are extensions of the neurons that receive signals

The tectospinal tract connects the midbrain and the spinal cord. It is responsible for motor impulses that arise from one side of the midbrain to muscles on the opposite side of the body. The function of the tectospinal tract is to mediate reflex postural movements of the head in response to visual and auditory stimuli. Damage signs would show prevention in being able to coordinate the head‚ neck‚ and eye movements. Sensory receptors perform countless functions in our bodies including mediating vision

Most of the neurons in the brain and spinal cord are unipolar. 9. In a contralateral reflex arc‚ the receptors and effectors are located on opposite sides of the body. 10. In an ipsilateral arc‚ the effectors and receptors are on opposite sides of the body. 11. Groups of cell bodies located in the brain or spinal cord are referred to as
