Final answer:
Theo is likely to perceive an uninvolved parenting style where emotions are not openly expressed, leading to potential psychological impacts such as emotional withdrawal and anxiety, and difficulties in social and academic performance.
Step-by-step explanation:
If Theo's parents never express any sort of emotion in the household, Theo is likely getting the impression of an uninvolved style of parenting which can have significant psychological effects. Based on psychological studies, this type of environment can result in children who are emotionally withdrawn, fearful, anxious, and possibly have an increased risk of substance abuse. Theo might also believe that emotional expression is not valued and may struggle to develop healthy emotional relationships or understand the emotional cues of others.
Furthermore, such a household dynamic can influence Theo's performance in school and other social settings, as the ability to express and manage emotions is crucial in these environments.
The absence of emotional interaction within the family could also lead to difficulties in forming secure and trusting relationships outside the family, impacting Theo's overall social development.
