The assignment discusses the psychology of children and adolescents, specifically a 12-year-old boy named Arthur who is experiencing behavioral issues such as decline in academic performance, sleep deprivation, and moodiness towards strangers. The tests conducted were mild and based on his achievements and IQ, with scores obtained from teachers and parents. The study highlights common problems faced by children during adolescence, including performance issues, peer pressure, and negative attitudes. Recommendations are made to engage Arthur in activities that align with his interests and provide special care and attention during this transitional phase.
