1. When compared to those who spend less time breast feeding as infants, children who feed from their mothers for a longer period of time will go on to achieve a greater level of intellect as adults.

2. Independent: In this case, the independent variable is defined as the amount of time spent breast feeding.
Dependent: In this case, the dependent variable is defined as each child’s achieved level of intelligence as an adult. 3. In this study, the operational definition of the independent variable is given by the amount of time each mother claims to have breast fed her child when she is interviewed at a one year examination. The given time frames are further divided into five categories.

In this study, the operational definition of the dependent variable is each child’s measured level of intelligence as determined by the Wechsler Adult Intelligence Scale (WAIS) when the group of children has reached a mean age of 27.2 years.

4. The sample used in this research is a group of both males and females who were born in Copenhagen, Denmark between October 1959 and December 1961. The sample size is more than 3,000.

a. The population that this sample seeks to represent is all the children of the world.

5. In this study, the researchers offer Wechsler Adult Intelligence Scale (WAIS) scores from the participating children as evidence to test their hypothesis.

The evidence in this case is empirical because the researchers have observed the measureable data through testing.

According to Merriam-Webster’s Collegiate Dictionary (2005), evidence can be defined as something which shows that something else exists or is true. Additionally, Merriam-Webster’s Collegiate Dictionary (2005), defines empirical as originating in or based on observation and experience.

6. The results of this study indicate that children who spent time breast feeding earned much higher scores on all aspects of the standardized intelligence test as adults. These findings were still found to be true after adjusting for other potential factors such as environment and genetic potential.
a. Although the results of this study are compelling and seem to be in accordance with the theories of many scientists, further reading on the part of this report’s author would be required in order to determine their reliability. However, evidence of similar studies yielding the same results would lend reliability to the aforementioned findings. With the information given, their reliability cannot be determined.

Merriam-Webster’s Collegiate Dictionary (2005) defines reliable as giving the same result on successive trials. Additionally, I find that this serves as an operational definition within the confines of this study.

b. Yes, the results are valid. The evidence presented by the scientists sufficiently justifies their findings and the testing is relevant to the parameters of the research. Merriam-Webster’s Collegiate Dictionary (2005) defines valid as well-grounded or justifiable: being at once relevant and meaningful. Additionally, the portion of this definition referring to justifiability and relevance serves as an operational definition in the context of this study.
7. As an explanation for their results, the researchers contend that various hormones and additional factors found in human milk contribute to greater brain growth and psychological development. This explanation does make sense based on the evidence they gathered; if human milk yields greater brain growth and maturation, then consuming larger quantities of this milk should increase a child’s intelligence relative to consuming less.

8. An alternative explanation for the results of this study could be that mothers who feed their child more formula and less breast milk may employ the services of a professional caregiver for their child. When a mother feeds her child exclusively breast milk, the assumption is that she is spending time directly in the presence of her child. When children are fed formula, the person providing the nourishment need not be their mother at all. The possibility exists that time spent in the presence of a loving mother could increase a child’s brain development, rather than the chemical composition of the milk she has to offer.

According to sociocultural theory, human development is a result of the way each individual reacts with their society (Berger, 2011, p.48). A mother could in such a way be considered a mentor to the child, who would receive different levels of attention based on time spent together (breast feeding).

In order to confirm this alternative explanation, the researcher would need to record whether or not mothers are the only individuals feeding their child if the child consumes formula rather than breast milk.

9. Because the descriptive, or field, method was employed in this study, the researchers can draw only a correlation between variables. Determining a cause and effect connection would require the scientists to conduct a laboratory experiment.
In the field method, variables cannot be manipulated enough to develop a sense of how each factor independently affects the other. Scientists can only observe and record the natural occurrences of factors and their results.
Merriam-Webster’s Collegiate Dictionary (2005) defines method as a way, technique, or process of or for doing something.

10. The practical applications of this research will primarily apply to the care of infant children. Mothers may want to consider the risks and benefits of breast feeding while taking into account the potentially increased brain development associated with breast fed children when compared to those who drink formula. Although breast feeding may still not be appropriate for all mothers (those with medical complications) this research should lend credit to the theory that breast fed infants will become more intelligent in their adulthood.

Also, mothers may want to take steps during their pregnancy to ensure that they can safely breast feed their children. In this way, they can potentially reap the benefits indicated by the study, without harm to themselves or their children.

Breastfeeding Benefits

...mothers cherish. There are many benefits that come with breast feeding. First, it provides natural antibodies that help your baby resist illnesses, such as ear infections, sore throats etc. Secretory immunoglobulin is a substance that works as the main immune factor. This substance guards against invading germs by forming a protective layer on the mucous membranes in your baby’s intestines, nose and throat (Baby, 1997). Second, it is usually more easily digested than formula. Babies that are breast fed are usually less constipated and gassy. I work with infants, and the bowel movements of the breast...

Impacts of Breastfeeding

...How Does Breast- Feeding impact cognitive, physical and socio-emotional development from Birth to Preschool Years? Psychology 230 Ms. Linda Pinney For many years there have been a lot of debates about rather breast-feeding or bottle feeding is better for a baby’s health. For the first few months when a baby is born the main source of an infant’s nutrients and energy either comes from breast milk or alternative formula. The growing census is that breast feeding is better for the baby’s health (Walker, 2010: Wilson, 2010), but how does it differ in the outcome of an infant’s social cognitive, physical and socio-emotional development during the first months and throughout the preschool years? Can breast-feeding really impact the success in a child’s life more than bottle-feeding? A recent Brazilian study showed that SGA babies scored significantly lower on the Bayley mental and motor subscales at 6 months and that the difference increased by 12 months [1]. Some studies followed the children for several years, and the findings sometimes changed with the age of follow-up. In American children who were assessed at 4, 5, and 7 years of age, language development, and reading readiness were worse in children who were not breast fed. Similarly, SGA Guatemalan children who had not been different from NEW children before 12 months had significantly poorer developmental levels in their second year and had lower scores on their cognitive...

Child Cognition Development in Early Years

...to fully develop their skills and provide them with a good learning environment as they go through their different stages in life. As I’ve been reading through the various materials on child development and as I’ve been learning about the different factors that contribute to a child’s health and learning, I find it that there are many things that we should take into consideration, as we too shall be raising children of our own in the future. I think that as parents it is our responsibility to guide our children so that they will be able to develop both their mental health and physical health the correct way, through ways such as correct sleeping patterns, different activities we do such as reading to them and talking to them, proper feeding and nutrition and by providing them with a safe environment that they could learn in as they develop their various motor skills and cognitive skills at a very young age. A child’s development is not solely dependent on the child’s own capabilities but is greatly dependent on the environment surrounding him or her. Regarding the debate of nature vs. nurture, I am more inclined to think that even though a child is in-born with his own set of physical and mental attributes genetically received from the parents, I believe that it is through the different experiences the child goes through, and through the different things they learn from the people around them, most especially their parents, that they...

Is Breastfeeding the Right Choice

...about it, the next breastfeeding is no longer the trend and formula is in. My purpose for this paper is to figure out if breastfeeding is truly the best choice for a baby. Being young and hopeful, I one day want to have a child of my own, so hopefully this research will allow me to decide if I will breastfeed my baby. There are a lot of advantages to breastfeeding an infant. The advantages appeal not only to the infant but also to the mother. To start out breast milk is always warm and ready compared to having to prepare a bottle of formula. Not only is breast milk always ready but it also is zero dollars. Formula can be extremely expensive to continuously buy. Breastfeeding is much more accessible and is the least expensive option. Along with being convenient breast milk also enhances brain development and the infants I.Q. in ways that formula cannot. A longitudinal study over a period of eighteen years involving one thousand children was preformed to show breastfed infants grew up to have both higher intelligence and academic achievement than those who were formula fed (Burby). Research has determined that a child’s first three years are the most critical in brain development. The infant’s nutrition during these essential periods in early growth and development permanently affects the structure and function of the infant’s organs and tissues. The infant’s nutrition starts in utero and continues with breastfeeding. Human milk is able to meet all of the challenging...

Research Paper on Breastfeeding

...What are the Benefits of Extended Breastfeeding? Researched Evidence that Identifies Benefits of Breastfeeding to the Child, the Mother, and the Entire Family What are the Benefits of Extended Breastfeeding? Throughout most of human history, breast milk has been the one food that infants have thrived on. Breastfeeding is recognized throughout the world as the preferred method of feeding infants due to its health benefits and nutritional quality. Recommendations by leading health organizations echo the importance of breastfeeding by setting forth guidelines. According to the American Academy of Pediatrics,” breastfeeding should be continued for the first year of life and beyond for as long as mutually desired by mother and child” (American Academy of Pediatrics [AAP], 2005). The World Health Organization (WHO) recommends breastfeeding infants for a minimum of six months, with added benefits when breastfeeding continues for more than a year. Their overall opinion is that the greatest health benefits occur when it is done for one or two years (Ryan, 2012). The United States national health objective, Healthy People 2010, set a goal to increase the number of women who breastfeed for at least six months to 50 %, focusing specifically on low-income women (Pugh et al., 2002). This research paper will look into the many benefits associated with breastfeeding for at least six months. First, what added health benefits does the infant receive if they...

Benefits of Breastfeeding

...Benefits of Breastfeeding Andrea Hicks This article discussed how breast milk provides the ideal nutrition for infants. It has the perfect mix of vitamins, protein, and fat -- everything your infant needs to grow. And it's all provided in a form more easily digested than infant formula. Breast milk contains antibodies that help your baby fight off viruses and bacteria. Breastfeeding reduces your baby's risk of having asthma or allergies. According to this article, babies who are breastfed exclusively for the first six months, without any formula, have fewer ear infections, respiratory illnesses, and bouts of diarrhea. They also have fewer hospitalizations and trips to the doctor. Breastfeeding has been linked to higher IQ scores in later childhood in some studies. The physical closeness, skin-to-skin touching, and eye contact all help your baby bond with you and feel secure. Breastfed infants are more likely to gain the right amount of weight as they grow rather than become overweight children. It's been thought to lower the risk of diabetes, obesity, and certain cancers as well but more research is needed to confirm these findings. The author of this article focussed greatly on the benefits breastfeeding when it is done for a specific tie frame. For instance; nursing your baby for 4-6 weeks, will ease his or her transition through the most vulnerable part of his infancy. The most important part of the article talked about...

Doh Breastfeeding Tsek Analysis

...estimated that high coverage of optimal breastfeeding practices could avert 13% of the 10.6 million yearly deaths of children five years old and below. Everyday, as many as 4,000 infants and young children die worldwide because they are not breastfed. According to United Nations Children’s Fund (UNICEF), it is because their mothers are not empowered with adequate knowledge about breast-feeding and do not receive enough motivation and support (UNICEF, 1994). Babies, their mothers, their families, their community, their environment, even the economy of the country in which they live, all benefit from breast-feeding (ibid). Realizing the great advantages of breast-feeding and the changing patterns of breast-feeding practice worldwide, the World Health Organization, 1981, recommended that all infants should be “exclusively breastfed for 4 to 6 months of age”(Kaunang, 1999). Moreover, UNICEF(1994) has advocated breast-feeding as one of the strategies for “ Child Survival” and exclusive breast-feeding as a best protective way for infants against infection and malnutrition. Nowadays, promotion of breast-feeding through Family Planning and MCH Programs is increasingly considered to be a public health policy priority especially in developing societies (Tin Oo, 1995). The Department of Health (DOH) advocates exclusive breastfeeding as part of their campaign in supporting the international goals of both the WHO and UNICEF in promoting infant health improvement and decreasing mortality...

The process of acquiring intelligence and increasingly advanced thought and problem-solving ability from infancy to adulthood. The purpose o f this research paper is to determine if all infants follow the same development process from infant to adulthood. There are many questions about the development stages of a child. I am sure many people would like to know if a child is born with cognitive skills or is that develop over time David F. Bjorklund explains “One issue central to all of psychology is that of nature versus nurture. Traditionally, this has been posed as a dichotomy: Is human thought and behavior genetically/biologically determined or is it shaped by learning/experience/culture? This is dealt with in a more sophisticated way today, in that everyone is an interactionist, with the issue being better expressed as “how do biological/endogenous factors interact with environmental/exogenous factors to produce the adult phenotype?” From this perspective, cognitive development does not simply mature, or bloom, over time, nor is it solely a product of a child’s culture; rather, it emerges over the course of ontogeny as a result of the dynamic and reciprocal transaction between a child’s biological constitution, including genetics, and his or her physical and social...

Down Syndrome Research Paper

...Treatments early in life will often help with physical and intellectual skills. Most of these treatments are used to help children with Down syndrome develop to their full potential. Many infants born with Down syndrome have poor muscle tone, which makes it harder for them to roll over or walk. Physical therapy is a treatment for these problems. An estimated 40- 60 percent of infants born with Down syndrome have a heart defect. Therefore, all newborns are checked out for a heart defect. Some babies with Down syndrome have eye problems, but surgery can help with that. Sucking problems related to low muscle tone my cause breast feeding problems.

...determination of EITHER (a) personality OR (b) intelligence. Draw on recent research to illustrate and support your answer. Intelligence has always been a very confusing topic in psychology. It can be a very difficult term to define since every individual can be intelligent in a particular aspect. Each and every person varies with their skills to adapt to the environment and how they can solve and understand intricate concepts. There are many different types of intelligence as there are many different skills in the world and they are all assessed on various criteria (Sternberg & Kaufman, 2001). The conceptualization of intelligence is still not set for certain as there are many different measures of intelligence. There is no standard measurement for intelligence and so there is no universal agreement of what intelligence actually is either (Plomin & McClearn, 1993). The research of intelligence found many different factors that determine the intelligence of an individual. The role of biology and genetic inheritance in the determination of intelligence is quite crucial. The genetic inheritance can be found out through how the child inherits the intelligence of the parent through IQ tests When mentioning the biology of intelligence, apart from the genetic inheritance that has to be researched through twin studies and adoption studies, hormones and neurotransmitters also has to be looked into in order to find out the biology of intelligence. The amount of nutrients that a child...

Breastfeeding – a Way to a Healthy Life

...demonstrate the advantages of breast milk feeding in early stages of human life and in years that follow. Discussion of non-scientific, i.e. social, economic, etc., aspects of breastfeeding will be limited, with primary focus given to human health outcomes for infants and mothers. The structure of this paper is decisively unconventional: where the author has chosen to discuss the body of common knowledge about breastfeeding before delving into the scientific research review. The intention is to draw the readers’ attention to the vast body of proven and observed advantages of breastfeeding for infant and mothers. Breastfeeding advantages – more than just food Breastfeeding is a natural process. Throughout human history breastfeeding was, and in many places around the world still is, a means to a healthy start to a human life. With the development of baby formula, and its availability, and relatively low cost, breastfeeding is now commonly thought to be a choice in the developed world. No longer a means to survival, no longer a requirement. To some, the advent of the baby formula is a direct form of feminine liberation. To others, baby formula is a necessity for medical or circumstantial reasons that are not driven by the freedom of choice. Those that choose the formula under pretenses other than necessity (e.g. absence of mother’s milk), are making a wrong choice. The advantages of breast milk are numerous. The most important one is that breast milk contains the perfect proportion...

Personal Narrative: My Life Of Mason

She recommended that we work on interpersonal communication. The specialist thought that Mason was slow to warm up to new situations with adults. As Mason turned nine months, the pediatrician has the following to say after a routine physical exam, a few items administered from the Bayley Scales of Infant Intelligence, and some observations of Mason in the playroom: Mason had an obvious attachment to me and prefers me over other people, but seems to have fun playing with my husband. I think me breast feeding him made him be so attached to me. At nine months, Mason is physically healthy. The doctor recommends a greater variety of baby food and ground up fruits and vegetables. Mason is cautious around new people and situations, but warms up fairly quickly to friendly people and to new and interesting activities and then begins to vocalize a lot and make eye contact. Mason has typical emotional reactions for his age, such as fear of total strangers, separation anxiety and a quick, loud cry when upset or in pain. Mason's motor skills are typical for age: crawling, sitting up, and standing up, but not walking...

Analogy of Killing Us Softly

...Through the movie Killing Us Softly 3, Jean kilbourne has given an interesting perspective in portraying to us what it means to be a woman according to the image we see in the media. She makes the argument that although it appears that women in this day and era have acquired power, it is a false sense of achievement and very short lived. She has dissected and discussed how the media and advertising companies have evolved in the last 20 years. Advertising is more a part of our lives today than it has ever been. In fact, advertising today has become a serious business with profits nearing 180 billion dollars a year, something that we all agree should be taken seriously. Consumers get bombarded by approximately 3000 ads per day and it has been estimated that the average consumers spends on average 3 years of their life watching just ads alone. No wonder that advertising is the foundation of the mass media. The problem that she points out is that while advertising is selling products it also perpetuates the ideas, values, beauty, and notions of love and happiness and, to a certain extent, the idea or concept of normalcy. This is the area that I personally have a problem with, since it also subliminally imposes on how to act, react and worst of all, be. How does advertising cause that effect? How can it be so powerful?

Chimpanzees In Dr. Jane Goodall's In The Shadow Of Man

...documentation of the social structures amongst chimps is an important component in breaking down the complexities of their relationships as well as making it possible to start creating parallels to human social norms. One example of this can be seen in the chimpanzee Mike and his rise to power. When Goodall started her work, Mike was ranked at the bottom of the adult male dominance hierarchy (112). Eventually, Mike used a “charging display” a tactic used to intimidate other chimps (114). Unlike other chimps, Mike used empty kerosene cans lying around camp: “Mike’s deliberate use of man-made objects was probably an indication of superior intelligence” (114). In addition, she observed that before a charging display Mike would show no indication of his emotions beforehand. His seemed to be preplanned and therefore further demonstrates his intelligence. To observe Mike’s charging displays as simple “brutish” is to ignore his ability to observe and use his surroundings to gain social standing amongst his peers. Mike’s ability to assess his position amongst his peers is comparable to the actions of what an adolescent male might do with a group of other group men to achieve respect. The community in Gombe illustrates the depth in chimp relationships and the chimpanzee’s high emotional capacity. “A chimpanzee community is an extremely complex social organization” (120). A society, which seemed so casual, actually remained organized and functioning because each individual knew his...
