To find the information you are looking for, you might need to consult reliable sources such as scientific research papers, books, or reputable websites. These sources can provide you with well-supported insights into adult thinking and behavior, specifically related to the influence of child-rearing practices and parental feelings towards their children.

1. Child-rearing practices: Research has shown that specific child-rearing practices employed by parents can significantly impact a child's development and later adult thinking and behavior. This influence may include factors such as discipline style, communication patterns, levels of involvement, and overall parenting approach.

2. Parental feelings: The emotional bond between parents and children can have a profound impact on various aspects of a child's development, as well as their later adult thinking and behavior. Parental warmth, acceptance, and emotional support contribute to positive outcomes, while negative emotions such as rejection or neglect can predict negative consequences.

3. Development predictability: It is important to note that while certain aspects of development may be influenced by child-rearing practices and parental feelings, not all aspects of development are predictable, and treating all children the same does not necessarily guarantee predictable outcomes. Each individual has unique characteristics, experiences, and genetic predispositions that contribute to their development and personality.
