To understand human growth and development, healthcare professionals need to understand and learn about 2 areas:
Knowledge of milestone competencies: Growth in the motor, cognitive, speech-language, and social-emotional domains
The eco-biological model of development: The interaction of environment and biology and their influence on development
This topic reviews the developmental stages of social-emotional development. It also discusses the role of the interprofessional team in identifying the cause of social-emotional problems and, therefore, intervening effectively.
Social-emotional development covers 2 important concepts, including the development of self or temperament and relationship to others or attachment. Clinicians can identify and intervene to resolve social-emotional problems in early childhood if they have a better understanding of these concepts.
Temperament
Temperament is an innate attribute that defines the child's approach to the world and his interaction with the environment across 9 dimensions, which are activity level, distractibility, the intensity of emotions, regularity, sensory threshold, and the tendency to approach versus withdrawing, adaptability, persistence, and mood quality. We can define temperament as the child's "style" or "personality," which is intrinsic to a child. It influences child behavior and interaction with others. Based on the above attributes that define temperament, researchers have categorized young children's temperament into 3 broad temperamental categories:
Easy or flexible: This category includes children who are friendly and easygoing, comply with routines such as sleep and mealtimes, adapt to changes, and have a calm disposition.
Active or feisty: Fussy children do not follow routines, have irregular feeding and sleeping schedules, are apprehensive of a new environment and new people, have intense reactions, and get easily upset.
Slow to warm up or cautious: Children who may be less engaged or active have a shy disposition toward new situations and new people and may withdraw or react negatively. They become more comfortable and warm up with repeated exposure to a new environment or person.
This classification is for ease of discussion, and all temperaments do not fit into 1 or other categories exactly. Discussing temperament with parents and caregivers can better identify the child's strengths and needs. Based on this, caregivers can adapt their management and caregiving styles to match the child's temperament. This can mold a child's behavior and facilitate the child's successful interaction with the environment, defined as "goodness of fit."
Attachment
The social-emotional development begins with parental bonding with the child. This bonding allows the mother to promptly respond to the child's needs and soothe their newborn. The consistent availability of the caregiver results in the development of "basic trust" and confidence in the infant for the caregiver during the first year of life. Essential trust is the first psychosocial stage described by Erickson. This allows the infant to seek parents or the caregiver during times of stress, known as attachment.
Even before acquiring language, babies learn to communicate through emotions. One may argue that knowing emotional regulation and impulse control may determine later success in life more than IQ. There is a rapid growth in social and dynamic areas of the brain during the first 18 months of life. The nonverbal parts of the right brain, including the amygdala and the limbic system, receive, process, and interpret stimuli from the environment that produce an emotional response and build the body's dynamic and stress regulatory systems.
The lower limbic system
The lower limbic system, outside the cortex, dictates most of our spontaneous, automatic emotional responses, like fear resulting in a racing heart or weak knees.
The upper limbic system
The upper limbic system part of the cerebral cortex, known as the limbic cortex, controls conscious awareness of emotions and refines the responses according to the environmental culture of the individual.
The amygdala
The amygdala is an almond-shaped structure that lies at the junction of the cortex and subcortical areas of the brain. It plays a pivotal role in sensing emotions and connects them to higher and lower limbic structures.
During the second half of infancy, emotional information from the more inadequate limbic system moves up and becomes part of the babies' consciousness. Frontal lobe activity increases, and myelination of the limbic pathways also begins during this time. With this gain in the limbic system, a caregiver's soothing and consistent response to the child's emotions develops into the child's attachment to the caregiver, usually the mother. Attachment is regarded as a pivotal event in a person's emotional development. It lays the foundation of a child's security, harbors self-esteem, and builds emotional regulation and self-control skills.
