Recommended: Harlow's experiment with humans
The study I chose to write about is “Harlow’s Monkey Experiments” (Baker, 2016)
Harlow’s Monkey experiment reinforced the importance of mother-and-child bonding. He suggested that the same results apply to human infants – that the timing is critical when it comes to separating a child from his or her mother. Moreover, it was found that the establishment of a bond between the infant and his or her mother is not purely dependent on the satisfaction of one’s physiological needs such as warmth, safety, food, but also emotional acceptance, love, and affection.
Harlow attended Stanford in 1924, and subsequently became a graduate student in psychology, working directly under Calvin Perry Stone, a well-known animal behaviorist, and Walter Richard Miles, a vision expert,

He would scare the infants and watch as the monkey ran towards the cloth model. Harlow also conducted experiments which isolated monkeys from other monkeys in order to show that those who did not learn to be part of the group at a young age were unable to assimilate and mate when they got older. Harlow’s experiments was terminated in 1985 due to APA rules against the mistreatment of animals as well as humans.According to Haraway, Harlow’s monkeys were compliant and passive willing subjects (Haraway, 1989 p 240). Many of Harlow's experiments are now considered unethical—in their nature as well as Harlow's descriptions of them—and they both contributed to the heightened awareness of the treatment of laboratory animals, and helped propel the creation of today's ethics regulations. The monkeys in the experiment were deprived of maternal affection, potentially leading to what humans refer to as "panic disorders". University of Washington professor Gene Sackett, one of Harlow's doctoral students, stated that Harlow's experiments provided the impetus for the animal liberation movement in the
The types of experiments performed at the University of Buffalo and the University of California depicts just some of the few horrors of animal testing. According to the article, during these experimentations the eyes of monkeys were implanted with metal coils into their eye sockets in order to study movement ("Update: Animal Testing"). Often times animals are tested upon in laboratories, living in cold isolated environments. The moral aspect of the debate, is whether or not animals should be utilized and later euthanized for the purpose of human benefit, especially when only one party decides. As a resu...
The attachment process plays a crucial role in a child’s development and their future impact on society According to Dr Suzanne Zeedyk. Children can’t feel relaxed and safe with the adults & children in the nursery until they get to know them. If there’s a lack of affection towards a child they may be reluctant to take advantage of all the learning opportunities because of their anxiety. We now know that relationships literally shape the neural connections in young children’s brains. This means everything that happens or doesn’t happen for the child will leaves a physiological trace in their growing brain. According to Dr Suzanne
The Strange Situation, in which infants are exposed to eight different episodes involving the mother and/or a stranger, is widely used to test attachments, although there are many different views regarding its validity and reliability. In order for the Strange Situation to be considered reliable, a child tested at different times should produce the same reaction every time; this was supported by Main, Kapland and Cassidy’s 1985 study which found that 100% of infants who had been securely attached before 18 months were still securely attached at 6 years, and 75% of those who had been anxious-avoidant remained so. One interpretation of attachment type (based on the Strange Situation) is that it is a fixed characteristic and therefore cannot be changed, but if there is a change in family circumstances this is often not the case. Attachments to mothers and fathers have been proven to be independent – Main and Weston (1981) found that children reacted differently depending on which parent they were with. This shows that the attachment types shown by the Strange Situation are based on qualities of distinct relationships as opposed to a child’s characteristics.
In 1976 Marshall H. Klaus and John H. Kennell came out with a book called “Parent Infant Bonding”. It discussed their hypothesis that like other animals, there is a brief moment directly following the birth of a child where skin-to-skin contact between mother and offspring creates a strong bond. Although this theory continues to be supported by many, some criticized the process of Klaus and Kennell’s studies. Some of these criticisms likely came from their definition of a “critical” time period after birth.
Harry F. Harlow was an American Psychologist who studied human behavior and development through studies of social behavior of monkeys. Harlow got his BA and PhD of Psychology from Stanford University. Then, later on got a job and did his studies at the University of Wisconsin. Harlow’s experiment consisted of young monkeys being separated from their mother right after birth. Then, the monkeys were raised in the laboratories which had mothers that were made up of wired mesh and another with wood and a terry cloth. When the infant monkeys were placed in the cage with only one mother was equipped with a nipple which was the wired mesh mother. It was placed so the infant monkey could nurse. Even though the wired monkey had nourishment, the young monkey would most often cling to the terry cloth mother. Harlow would place a monkey inside a cage. Then, began to make loud noises against the cage or play recordings that made the monkey feel insecure. The monkey always seemed to go toward the terry cloth mother as it began to get scared. The infant monkey would go for comfort, but eventually would get nourishment from the wired mother.
An article written by an animal researcher and psychology professor discusses the lack of ethical treatment towards primates in research labs. The author of Second Thoughts of an Animal Researcher, John P. Gluck, justified the unethical treatment of primates by believing that scientific advancements are superior to the harm the primates experienced. One day a student of his presented a dissertation about a female rhesus monkey who unexpectedly passed away. The dissertation caused Gluck to feel that the animals he caused much harm to were more than objects used to create data. Although he tried to continually justify his actions, he eventually felt guilty and decided that the primates deserve to be handled ethically. Throughout the article,
The attachment style that a child endures with their mother initially begins before the child is even born. In the mother’s womb, the infant becomes aware of their mother and father’s voices, where they begin to develop a bond with them and feel nurtured and comforted by the things they hear their parents sing and speak to them. According to Bowlby, the development of attachment takes place in four different phases and are reinforced as they grow older from the Preattachment (birth to age 6 weeks), attachment-in-the-making (age 6 weeks to 8 months), clear cut attachment (between 8 months to 1 ½ years of age) and the reciprocal relationship (from 1 ½ or 2 and on). As the child grows older, then begin to understand their parent’s feelings and motives and are able to organize their efforts and reciprocate the same i...
The attachment theory, presented by Mary Ainsworth in 1969 and emerged by John Bowlby suggests that the human infant has a need for a relationship with an adult caregiver, and without a subsequent, development can be negatively impacted (Hammonds 2012). Ainsworth proposes that the type of relationship and “attachment” an infant has with the caregiver, can impact the social development of the infant. As stated by Hammonds (2012), attachment between a mother and a child can have a great impact on the child 's future mental
The Scopes Trial, formally known as The State of Tennessee vs. Scopes but given the nickname “The Monkey Trial”, has been credited as starting the popular legal dispute between evolution and creationism in the court, and its impact in the 20’s was immeasurable.
Infant attachment is the first relationship a child experiences and is crucial to the child’s survival (BOOK). A mother’s response to her child will yield either a secure bond or insecurity with the infant. Parents who respond “more sensitively and responsively to the child’s distress” establish a secure bond faster than “parents of insecure children”. (Attachment and Emotion, page 475) The quality of the attachment has “profound implications for the child’s feelings of security and capacity to form trusting relationships” (Book). Simply stated, a positive early attachment will likely yield positive physical, socio-emotional, and cognitive development for the child. (BOOK)
These experiments that were conducted on the monkeys have a high chance of encouraging other countries to take the same actions and produce their own experimentation. If other countries were to be suspicious of the actions that the scientists have taken they too might undergo certain testing. Take Russia as an example. They are another country, other than the Unites States, that have their hands on the smallpox virus. They too can begin experimenting on animals if they believe this virus can be a threat. Some felt, “the biggest danger of Jahrling’s research was that it would look suspicious to other countries and would encourage them to do their own experimentation. We would start an arms race over small pox.” (211). Preston claimed that, this
The “strange situation” is a laboratory assessment used to measure infants’ attachment to their mothers through observation, by providing a series’ of experiences of introductions to a stranger, separations from mother and then the reunion of the two. The “strange situation” measures the infants’ attachment in being securely to insecurely attached with the mother. The scene of the experiment is set up in a small room with mother, child and stranger, they will then follow a prescribed order of the series listed above. At first it’s only mother and child, and then the stranger joins the room. The mother tends to the child briefly and then leaves the room, leaving the child with the stranger. The child then expresses distress to a certain extent – depending on the degree of secure attachment to the mother – upon the mother’s departure and cries in calling the mother back. The mother returns and stranger leaves. The next step is then that the mother leaves the child completely alone, and when child then cries in a call for them to come back, the stranger will return instead of the mother, this is an important part of the experiment in order to determine the child’s attachment. It gets determined whether or not the child will return to a calm state of mind with the calming of the stranger. The mother will finally return to the child again and stranger will leave as the experiment and observation
Through the well-studied idea of maternal-infant attachment there has been important insight into a child’s development. Mary Ainsworth found through her “Strange Situation” experiment that there are three distinct types of attachment that infants form; anxious avoidant, secure, and anxious resistant (O’Gorman, 2013). Later a fourth attachment style known as, disorganized attachment, was identified (CITE). Secure attachment is linked to maternal sensitivity just as insecure attachment is linked to maternal rejection or unpredictable maternal response to an infant’s desires and needs (Kinsvatter, Desmond, Yanikoski, & Stahl, 2013). Infants are “at risk” of developing an insecure attachment to their mother when they are placed in alternative care before nine months of age (Stifter, Coulehan, & Fish, 1993). This is concerning in that we see there are negative effec...
The mother to child bond has been interpreted to be instinctive to all mothers. Meira Weiss quotes
Attachment occurs in stages. The first stage is pre-attachment, which occurs from birth to 6 weeks. During this stage newborns get an adult’s attention through smiling, crying, babbling, and making eye (Divecha, 2017). Although, they are not attached to their mother yet, they feel soothed and calm when they are carried by her or feel her presence (Divecha 2017). The second stage occurs between 6 weeks and eight months. The infant begins to develop trust in his or her mother and relies on her all of the time. When the child is comforted by the mother, they begin to smile because they feel trust (Divecha, 2017). The infant loves the company of their parent or caregiver and gets distressed when attention is not given to them (McLeod,
