Harlow Monkeys

I found the article in Chapter two about the Harlow monkey study to be particularly fascinating , if not rather sad. The fact that caught my attention most was the section that discusses the placement of a scary toy inside the cage. More then establishing a desire for comfort, it established the need for love or comfort to confront fears and learn. The polar differences in reactions, some trepidation but eventual exploration vs. extreme fear to the point of shaking and even urination from the baby monkeys speaks allot about the importance of a loving mother in a child's development. The three grand theories that we read focus allot on individual behavior and many studies focus on bad parenting creating bad habits or malformed emotions, but I would love to learn more about the role of a mother's love, or lack there of, effecting early behavior. For example, do babies who are held more and experience higher levels of love and comfort than other infants learn to walk earlier, do they have higher intelligence levels. I have previously read a case study of sorts, (that I can't seem to find a copy of to reference on line) that told an anecdote of a king who wanted to study language and so isolated a group of babies who were only allowed to have access to people for necessary care and they all died. The king attempted to have the study repeated, but again all the babies died. What this was evidence of, similar to the Harlow study, was that babies need more then just warmth and care, they need love and stimulation in order to survive. What this case study didn't speak of was that love and care being essential to how babies react to unknown objects. If anyway know about this or has read articles about it, I'd love to see them!
