Final answer:
Tristian's parents display an uninvolved parenting style, characterized by minimal attention to his needs and few demands, which can lead to negative emotional and academic outcomes for the child.
Step-by-step explanation:
Tristian's parents are best categorized as having an uninvolved parenting style. The characteristics of this style include indifference and a lack of responsiveness to the child's needs, making relatively few demands. This can sometimes stem from issues such as severe depression, substance abuse, or an extreme focus on work, and these parents tend to provide only for their child's basic needs. Children raised in uninvolved environments are often emotionally withdrawn, fearful, anxious, and may perform poorly in school.
