Aggression is a behavior directed towards another intended to harm or injure. Neurotransmitters are chemicals that enable impulses in the brain to be transmitted from one area of the brain to another. There’s evidence that the neurotransmitters serotonin and dopamine are closely linked to aggressive behavior. Low levels of serotonin and high levels of dopamine have been associated with aggression in both animals and humans.…
Behaviour can be describes in many forms and ways. According to the dictionary ‘Behaviour is the manner in which one behaves, the actions or reactions of a person or animal in response to external or internal stimulation’ (www.thefreedictionary.co.uk). Harlow was an American Psychologist who investigated the bond of infants to their mother. The reason for this investigation was to see if the bond was due to cupboard love. Cupboard love is what the infant is attached to such as providing of food or something warm and soft to touch. However Bowlby had already said that the bond with the infant to the mother was to do with something other than cupboard love. Bowlby stated ‘an inbuilt tendency to become attached to stimuli that poses certain properties’ (discovering psychology, chapter5, pg201). Harlow who wanted to conduct his study on rats accidentally conducted it on medium sized monkeys known as (Macaca Mulatta). The reason for using this particular type is that they are easy to keep and breed in captivity; they also share 94% DNA to a human. After securing funding for a primate laboratory, Harlow started his work. However when cleaning the cages the infant monkeys would protest, Harlow then went on to find out whether the monkeys were on protest due to ‘contact comfort’. To test the idea of contact comfort Harlow constructed two types of surrogate mothers. One of…
It has been shown that impulsive behavior and aggression have been associated with having low levels of serotonin. Evidence for the role of serotonin comes from the use of drugs that raise levels of serotonin in the brain, such as antidepressants. In clinical studies, antidepressant drugs which increase serotonin levels also tend to reduce irritability and impulsive aggression. This suggests that increased serotonin levels do lead to reduced aggression.…
Social releasers are instincts that babies are born with to attract parent’s attention. These included crying, sucking, clinging, gripping and imitating. These help in attachment because they release/ trigger the parent’s instinct to respond to the biological needs of a baby. This had been supported by Klaus and Kennel who stated that mothers who had prolonged skin to skin contact with their mothers had a stronger attachment bond. The time had enabled the parents to ‘switch on’ their maternal instincts. However, this has been criticized because maternal instinct can always be there not just when you’ve had a baby so most women’s hormones make them react to…

Bowlby’s theory is an evolutionary theory because, in his view attachment is a behavioural system that has evolved because of its survival value and, ultimately, its reproductive value. According to Bowlby, children have an innate drive to become attached to a caregiver because attachment has long-term benefits. Both attachment and imprinting ensure that a young animal stays close to a caregiver who will feed and protect the young animal. Thus attachment and imprinting are adaptive behaviours. Infants who do not become attached are less likely to survive and reproduce. Attachment ‘genes’ are perpetuated, and infants are born with an innate drive to become attached.…
“Attachment is relatively long term, emotionally important relationship in which one individual seeks proximity to and derives security and comfort from the presence of another” (Investigating psychology, 2012 p. 193). Harry Harlow and Mary Ainsworth are two famous psychologist who provided us series of experiments to understand the attachment in terms of psychology. HarryHarlow started the experiments on monkeys and Mary Ainsworth focused on human infants’ behaviour. There are various similarities and differences in their sets of experiments by using different techniques.…

After observation, it states that with an insecure attachment it may lead to violence within dating. Male and females have a different way of reacting to rejection. Males are prone to be more sarcastic and there are more conflicts, and females tend to retreat. Anxiety and avoidance of intimacy was also studied with in the adolescent group of boys and girls. It was found that boys with anxious or avoidant attachment styles hold attitudes, which they use to justify their aggressive actions. Girls with anxious attachment style is prone to be aggressive verbally and physically towards their partner. The main focus is to educate adolescents…

The first control (control-vp) was injected with a vector that expressed lacZ in the ventral palladium. The second control (control-other) was given a viral injection to a different part of the brain. The tested group (V1aR-vp) was injected in the ventral palladium with a vector that expressed V1aR (Lim et al. 2004). The three groups placed in a pen with a sole female for 24 hours before being moved to a new pen with the same female and a new female for three hours. After studying the time spent with each female, it was determined that the males in the V1aR-vp group chose to spend time with the original female vole than the newly introduced female. Lim et al. (2004) determined that the treatments given to the control groups had no effects on the social behaviors of the voles because these males had no preference to either of the introduced females. It was determined that partner preference was the cause of the additional time spent with the first female rather than just an affiliative behavior because the control groups spent less overall time huddling whereas the V1aR-vp group spent equal amounts of times with the second introduced female as the control groups (Lim et al.…
This is characterised by the child keeping at a distance from the caregiver, and displaying little distress at separation. This occurs when the primary care figure is inconsistent, and does not provide the child a secure base (Passer & Smith 2013, p. 432).…
What is Attachment?:- “Attachment is the close bond between two people which endures over time and leads to certain behaviors such as proximity seeking, clinging and distress on separation, These behaviors serve the function of protecting an infant”…
Examples include children who are living in unstable, high stress homes with few or no resources, attain puberty at an early age, invest less in their offspring than children from stable, low stress homes (Curly, 2011). A baby’s attachment with the caregiver may have served to increase that infant’s survival during a time in ontogeny ensuring close proximity to mutual affection (Curly, 2011). It has been reported that the OPRMI gene has been associated with the behavioral variation in infant attachment in rhesus macaca which shows a co-adaption of the gene OPRMI in the framework of mother infant relationships. Opioids are said to be important controllers of maternal behavior in offspring by matching the onset of maternal behavior with parturition and maternal affect, during evolution, the function of opioids have achieved the additional role of facilitating both infant attachment and maternal care (Curly,…
