This report presents an assessment of Maria Jenkins, a two-year-old child, focusing on her cognitive, psychosocial, and behavioral development. The assessment utilizes Piaget's theory of cognitive development to evaluate Maria's perceptual skills and conceptual learning, examining her responses in sensorimotor and preoperational stages. Erikson's theory of psychosocial development is applied to understand Maria's interactions with her parents, particularly the development of trust and autonomy. The report also investigates the influence of Maria's home environment, drawing on social learning theory to analyze the impact of parental care and interaction on her behavior. The findings highlight the importance of parental involvement and a supportive environment, offering recommendations for the parents to foster Maria's healthy development, including equal time and guidance. The report concludes that by implementing these recommendations, Maria's behavioral issues can be addressed, leading to positive changes in her development.
