Many researchers have wondered the effects of pre-natal stress on developing organisms and it’s influence on their development. This is especially important when it comes to reproduction of humans and how people can ensure that human babies will not develop conditions that would impede their own attempts of reproduction or be detrimental to their health. By studying the effects of pre-natal stress on rats, it allows scientists to gain an understanding of how environmental factors can affect their future offspring. The purpose of this study was to identify how pre-natal stress influences sexual behaviors of male rats. We conducted one study and sought to determine to what extent does pre-natal stress influences sexual behaviors of male rats by observing the number of mounts and the number of latency of male rats when they are placed in a cage with normal female rats.
Previous researchers have conducted similarly studied the effects of pre-natal stress on rats. Frye and Orecki (2002) studied how pre-natal stress altered sexual, explorative, and social behaviors of Long-Evans female rats. They conducted …show more content…
One limitation of the study is the breeds of rats being used in the study. We only used one breed of rats in our study instead of a variety of rats. Perhaps PNS affect different breeds of rats more than others. The second limitation of this study is the number of ways the mother rats were stressed because the restraining tubes and heat lamps do not fully emulate a natural environment for rats. If rats were given more environmental related stressors, it could impact the level of PNS in male offspring. The third limitation of the study is the environment of the cage that the male rats were placed in with the female rats. The presence of the university researchers could have made the rats feel more uncomfortable and less likely to attempt reproductive

    Stress, Portrait Of A Killer: A Documentary Analysis

    The animals blood pressure skyrockets to deliver the life-saving energy and all non-essential bodily functions shut down (i.e. growth, tissue repair, and reproduction). As, Stanford University Neurobiologist, Robert Sapolsky puts it, “You know you are running for your life, this is no time to ovulate.” Your body knows that these functions can be done later if there is a later. When the animal escapes the stress response shuts down. Unfortunately, humans have evolved to a point where we can’t seem to find the off switch for the stress…

    More Experience: Bigger Brain By Roger R. Hock

    However other scientists were skeptical towards to the experience, since in the past research such effect was not demonstrated. The author also mentions how some scientist criticized that perhaps it was not the enriched environment that produced that brain change, but rather the how the rate was handling or stress. In addition, argument was made that the impoverished rat was stressed, and that’s what made that change in the development of the brain. In the further addition, the authors mention that others studies suggested that the effect on growing brain can either be reduced or increased, based on how the…

    Monkeys In Harlow's Study

    In Harlow’s studies, monkeys were raised by a wired mother that is able to feeds them and a clothed mother. He found the baby monkeys would spend more time with the clothed mother since it offered a sense of security to the baby rather than the wired mother that fed them. The discovery of the fact that the sense of security would overshadow the other variables such as nursing enough for the monkey to spend more time with the clothed mother surprised Harlow. Overtime when the monkey was frightened and ran to the clothed mother, the baby would eventually calm down due to the presence of the mother. This is shown when Harlow presents a fear-provoking contraption to the baby.…

    Critically evaluate evidence that maternal deprivation in infancy has long-term effects on human social and emotional development in an essay of 1,000 words. When considering the question, of whether maternal deprivation in infancy has long-term effects on human social and emotional development, we have to first understand what social and emotional development is, and the psychological approaches which study these aspects. Psychosocial psychology, studies how a persons thoughts, emotions and behaviours evolve in response to their social environment. When looking at social development, we are specifically studying how children develop attachments and how they communicate and interact, within and around these attachments.…

    Residential Atrazine Study

    Many herbicides and pesticides are thought to be involved in teratogenic, or embryonic development disturbing, mechanisms. Therefore it is important to study the effects of these chemicals on humans and wildlife in the event of contact or contamination. Case-Control Study of Maternal Residential Atrazine Exposure and Male Genital Malformations by Agopian in 2012 is one study that examines an herbicide, atrazine, in relation to birth defects of male genital development. Atrazine is one of the most widely used herbicides in the United States, with teratogenic effects suggested for multiple classifications of birth defects (Winston et al., 2016). Agriculturally, atrazine has an estimated half-life of a few weeks to several months, and is used to control broadleaf weeds and…

    Child Development Theory Comparison Essay

    After researching and comparing four theories, similarities begin to emerge and create an intertwined picture of childhood. Each of the theorist developing their own thoughts about how they perceive child development, hoping to explain to people with actual knowledge the patterns of children’s emotional, cognitive, physical and social growth. Starting at the first stage (birth to 1 year), Erickson, Piaget, and Fraud all grasp at the idea of oral stimulation as a way for the emerging child to join the outside world. Infants coming into this world are hopeless mammals that depend on loving adults to care for them. “Attachments are theorized to serve an evolutionary purpose because they increase the likelihood that the caregivers will protect and care for the infant.”…

    Nature Of Behaviourism

    The aim of this assignment is to discuss how nature and nurture applies to attachment by applying the principles of behaviourism. An attachment is an enduring, two-way, emotional tie to a specific other person usually between a parent and a child which develops in set stages within a fairly rigid timescale (Lawton, et al, 2011. p. 39). Whereas behaviourism is a belief that behaviours can be measured, trained and changed (Cherry, 2010).…

    pre term time which involves the negative or traumatic birth experience and the hospitalization of the baby in neonatal intensive care unit can be a stressful time for mothers causing psychological distress which is associated with subsequent emotional and behavioural problems of the child (Miceli et al, 2000). The physical separation also hinders mothers from form secure attachment with their babies. Secure attachment can be the foundation to a child development in terms of their biological, social, emotional and positive behaviour adjustment in adulthood. (Granot and Mayseless, 2001). On the contrary, insecure attachment is linked with emotional and social problems and also results in biochemical consequences in the developing brain(Levy…

    Essay On Maternal Deprivation

    When considering whether maternal deprivation in infancy has long-term effects on social and emotional development, we have to first understand attachment is. Attachment can be defined as a “long-enduring, emotionally meaningful tie to a particular individual” (Gross and Rolls, pp!!!!!!, 2008). Bowlby – a key figure in the study of attachment – strongly believed that attachment behaviours provide the evolutionary advantage of protection. He hypothesised that we developed a gene to code for attachment, this gene, he speculated, turns on at the start of the crawling phase and subsequently switches off at approximately 3.5 years old – He called this time frame a critical period.…
