links on dismissive and disapproving parenting; also, attachment.

Dismissive parents (bolds mine):
http://www.teach-through-love.com/dismissing-parent.html:

Children learn that their feelings are wrong, inappropriate or invalid. They may learn that there is something inherently wrong with them because of the way they feel. A child cannot understand why the emotions she is feeling are not recognized by the parent as valid. A child may have difficulty regulating her own emotions and the emotional connection with the parent is lost in favor of glossing over tough feelings.

Disapproving parents (bolds mine):

The disapproving parent often tells a child she should not feel the way she feels. If a child is sad or upset and is crying or about to cry, a disapproving parent will tell the child to stop crying. If the child continues to cry, the parent may go so far as to tell the child to stop crying or she will be in trouble.

Not only is the child upset or angry over something, but now she is in trouble for having these feelings. The child is going to be punished even though she did nothing wrong. Disapproving parents see emotion as a choice. You choose to feel a certain way and you can choose to feel otherwise. Emotions are seen as a negative.

This sends the message that children should not express sadness or anger. This does not help the child, as the cause of the child's feelings has not been determined, and never will be.

Children who grow up with disapproving parents may have a hard time trusting their own judgment, think something is wrong when they have negative emotions, feel alone, have low self-esteem and have trouble dealing with their emotions. They may lack problem-solving skills and have difficulty with concentrating, team work and learning. These children can also build up tremendous frustration toward their parents that harms the parent-child relationship during the adult years.

Need for secure attachment (bolds mine):

John Bowlby concluded that the most dangerous event for baby mammals, including humans, is separation from a protective adult. Conversely, Bowlby recognized the need for exploration as being essential to survival. His hypothesis was that when children feel safe and secure, their attachment system terminates, and their exploratory system engages. This allows for both optimal safety and the mastery of necessary skills. However, when children feel threatened, exposed, criticized, or vulnerable to attack, their exploratory system terminates and their attachment system is activated.

The reciprocal relationship between seeking protection and developing new capacities presents a challenge for children and adults alike. This dilemma occurs because there exist a strong evolutionary advantage for seeking protection, when needed, to override all other systems, thereby becoming the only system active. In other words, people cannot adequately learn and defend themselves at the same time.
