Assignment Brief


Assignment Brief:
Explain and evaluate the ways in which the nature-nurture might determine people’s behaviour using psychological research that has been applied to intelligence and gender differences in humans.

You are a writer for the “Psychologist” magazine and have been given a task to research the nature/nurture debate with a particular focus on intelligence and gender. You must include lots of psychological research and evaluation (conflicting evidence, strengths and weaknesses) on both sides of the debate and then come to a conclusion.

The title is “Is Human Behaviour Learned from the environment? OR is it Inherited from your parents?”
  



References must be included using the Harvard format.

Does Society influence the gender role of a child?

Meet the parents who are raising a 'genderless' baby A Canadian couple has decided to keep the gender of their baby a secret in order to provide it with 'more choice'.… Posted By Yahoo Lifestyle, Wednesday, 25 May 2011 12:28 BST For most of us, as soon as a pregnancy is announced, the gender guessing game begins. And while some like to keep the sex of their baby a secret until the child is born, one couple has taken a decidedly different approach on revealing the sex of their offspring. A Canadian couple from Toronto have decided to keep the gender of their four-month-old baby a secret in order to raise what they call a 'genderless' child. Storm will be raised as neither a boy nor girl and will choose a sex when he or she grows up. Kathy Witterick and David Stocker have only revealed Storm’s gender to close members of the family, including their two young sons, one friend and the midwives who delivered the child. After Storm was born on New Year’s Day, the parents sent out an email to the rest of their friends and loved ones, writing: “We’ve decided not to share Storm’s sex - a tribute to choice in a place of limitation, a stand up to what the world could become in Storm’s lifetime ( a more progressive place?...).” The couple told the Toronto Star about the flood of unsupportive comments they have received. Friends expressed their fears of how Storm’s genderless nature would make the child vulnerable to bullying in the future. Another concern was that they thought the couple were actually taking away the newborn’s right to choice, by forcing their own ideology on the tot. Defending their decision, Kathy said, “With the baby, even the people who love the most and know you intimately, the first question they ask is, ‘“Is it a girl or a boy?”’ David added, “If you really want to get to know someone, you don’t ask what’s between their legs.’ Kathy and David feel strongly about releasing their children from the constraints that society poses on males and females and want them to make their own decisions about how they act and look. Their sons Jazz, five, and Kio, two, have the freedom to dress themselves and decide when they want to cut their hair. Kio’s favourite colour is purple and older sibling Jazz has long hair, he likes pink. After being mistaken for a girl and home schooled because of how people would, “immediately react with Jazz over his gender” the couple decided to raise Storm genderless.

Are we born with intelligence or is it learned?

Are we born with the intelligence that we end up with or is intelligence a matter of learning through life? In short, is intelligence a product of nature or nurture? The Origins of Intelligence What accounts for the differences in people’s intelligence? It could be biological in the nature of the genetics a person has inherited, or it could be the environment they have around them or even the culture that they live in. Hereditability studies have been conducted to find out the answer to the differences in intelligence. These studies tend to be conducted on twins because monozygotic (identical) twins share 100% of their genes. They are, if you like, nature’s clones. The studies show that the type of intelligence that produces high scores on IQ (intelligence quotient) tests is highly heritable. In twin studies, the scores of identical twins are always more highly correlated than those of fraternal twins. In fact, scores of identical twins that have been reared apart are more highly correlated than those of fraternal twins that have always been together. Intelligence then can be considered highly heritable because the higher the parental scores, the higher their offspring scores tend to be. However, sibling’s intelligence can vary widely. This shows that a highly heritable trait can be modified by environmental factors. Good diet and good pre-natal care are beneficial to a baby’s intelligence and conversely, a mother who smokes and drinks or takes drugs during pregnancy may harm the baby’s intelligence. Other factors that have been shown to reduce the child’s intelligence include environmental pollutants and even malnutrition, if the mother doesn’t eat properly all play a part during the nine months of pregnancy. Poor pre-natal care has been shown to hinder IQ in the baby. Each risk factor can reduce a child’s IQ by 4 points and if two or three risk factors occur together then the child’s IQ can be lowered by 20 points. Atmospheric pollutants can produce attention problems, lower IQ scores and poor school achievement. It is often difficult to separate the relative influences of heredity and environment on human characteristics. People who have similar genetic makeup (e.g., brothers and sisters, parents and their children) typically live in similar environments as well. So when we see similarities in IQ among members of the same family, it is hard to know whether those similarities are due to the genes or to the environments that family members share. Nevertheless, a significant body of research tells us that both heredity and environment affect intelligence. Twin studies Many studies have used monozygotic (identical) twins and dizygotic (fraternal) twins to find out how strongly heredity affects IQ. Because monozygotic twins begin as a single fertilized egg which then separates, they are genetically equivalent human beings. In contrast, dizygotic twins are conceived as two separate fertilized eggs. They share about 50 percent of their genetic makeup, with the other 50 percent being unique to each twin. If identical twins have more similar IQ scores than fraternal twins, we can reasonably conclude that heredity influences intelligence. Most twins are raised together by the same parent(s) and in the same home, and so they share similar environments as well as similar genes. Yet even when twins are raised separately (perhaps because they have been adopted and raised by different parents), they typically have similar IQ scores (Bouchard & McGue, 1981; N. Brody, 1992; Mackintosh, 1998; Plomin & Petrill, 1997). In a review of many twin studies, Bouchard and McGue (1981) found these average (median) correlations: Correlations of Twins’ IQs: Identical twins raised in the same home .86 Identical twins raised in different homes .72 Fraternal twins raised in the same home .60

Case Studies that could claim the nurture side of the debate

 

Feral Children


 1.2  An article in Scientific American suggested that humans have been around in their present form for 120,000 years. However, we only discovered language and became technologically creative as late as 40,000 years ago. So what were humans like before that? And what would we be like if the influence of our current society was not present?

1.3  Feral children are children who have spent much of their formative years in the wild, without any contact with other humans for a significant period of their lives. Cases of feral children are thankfully rare, but are of immense interest from a scientific and educational point of view. Feral children provide data which help to answer a number of questions:

  • How close is human nature to the nature of an animal?
  • What aspects of human nature are genetic, and what aspects are learned?
  • What does consciousness mean?
  • Could we learn how to speak to animals, or could we teach animals to speak to humans?

1.4  Studies of feral children in the past have lead to breakthroughs in the education of people with learning disabilities, and indirectly has lead to the development of sign-language and Braille.

1.5 Stories of feral children pop up every now and again in the media, but most stories are  uncorroborated, and many are pure fantasy. However, there are a few cases which did occur in history which were the subject of intense scientific scrutiny.

1.6    Here are a few of the celebrated cases in the history of feral children.

1.7 Wild Peter

In 1724, near the German town of Hamelin, a boy, described as a naked brownish black-haired creature, was seen running up and down in the fields. The boy was enticed into town, and once there immediately became a subject of great interest. He behaved like a trapped wild animal, eating birds and vegetables raw, and when threatened, he sat on his haunches or on all-fours looking for opportunities to escape. Peter was soon made the possession of King George I of England, where he lived the rest of his life. During his life Peter never learned to talk, showed a complete indifference to money or sex, and was never seen laughing. However he loved music, could be taught a number of menial tasks, and when he once got lost, he found his own way back home. Peter died in 1785.

 

1.8  Victor, The Wild Child of Aveyron

Victor, a boy of about 11 or 12, was discovered foraging for roots and acorns in the woods near Aveyron, France in 1799. Victor was taken to Paris, where he appeared to be human only in appearance. Victor behaved like an animal, ate rotten food with pleasure, was incapable of distinguishing hot from cold, and spent much of his time rocking back and forth like a caged animal. Victor was taken into the care of the brilliant scientist, Dr Jean-Marc-Gaspard Itard, who dedicated himself to the education of the boy. Victor proved to be a very difficult subject. Over the years, Victor only learned two terms, 'lait', and 'oh Dieu'1. His sense of touch seemed to be far more important than his sense of sight, he did not demonstrate an ability to distinguish right from wrong, and like Peter before him, he was indifferent to sex. He did however, learn some menial tasks, such as setting a table. Victor lived the rest of his life in the care of his housekeeper, and died in 1828 at the age of 40.

 

1.9  Kaspar Hauser

Kaspar was discovered in 1828 in Nuremberg, Germany. He was unsteady on his feet, and only spoke the phrase 'I want to be a horseman like my father is'. Kaspar was about 16 years old, but he behaved like a small child. It appears that for most of his early childhood, Kaspar was imprisoned in a cage, with hardly any contact with the outside world. When a mirror was handed to him he used to look behind him to find the person in the mirror, and could not understand how faraway objects appeared smaller than objects close by. Kaspar had a keen sense of smell. He detested meat and alcohol, and was offended by the smell of flowers. He loved wooden horses, and he thought the sky was full of candles. Unlike many other of the cases described here, Kaspar did learn much, but in 1833 he was assassinated. The mystery of his early life and violent death have never been satisfactorily answered.

 

2.0  The Indian Wolf-Girls Kamala and Amala

Two young girls were discovered under the care of a she-wolf in 1920, in Godamuri, India. The girls were taken to an orphanage in Midnapore (now part of Orissa). When they were discovered, their "rescuers" actually removed them from the embrace of a pair of wolf cubs in order to take them back to The children, Kamala, aged eight and Amala, aged 18 months, behaved exactly like small wild animals. They slept during the day and woke by night. They remained on all-fours, enjoyed raw meat, and were given to biting and attacking other children if provoked. They could smell raw meat from a distance, and they had an acute sense of sight and hearing. The youngest child, Amala, died one year later, but Kamala lived for nine years in the orphanage until she died of illness at the age of 17. Kamala did acquire a small vocabulary, but she remained very different to other children until the time of her death.

 


A young boy that was adopted and reared by a local colony of African Green monkeys apes in the dense African jungles of Uganda, until being found, scavenging for food in the company of his fellow apes, by a tribeswoman in 1991.

The boy was then taken to the Kamuzinda Christian Orphanage, 100 miles from the Ugandan capital Kampala, where he lived with the family of the orphanage manager. For the next few years John learned how to speak and to behave in a human manner, being able to tell his incredible ordeal himself.

Hillary Cook, a 56 year-old British dentist who was working in Uganda at the time, meet John and passed the story along to the BBC, which verified its veracity by going to Uganda and talking to all of the witnesses and parties involved on his rescue, education and reintegration to society.

John's remarkable story was featured in “Living Proof”, a television documentary screened on the BBC, October 13, 1999.

2.2  The wild boy of Hesse

A wild boy found in the woods of Hesse, Germany, in 1341. He appeared to be about 7 years old and supposedly had been kept by wolves.

This boy apparently died soon after being captured, but a second wild boy was seized three years later (1344) in the same region and reportedly lived to the age of 80 years.

According to records, both children were wild and immune to cold and discomfort, besides not being able to stand upright, consequently having to move around on all fours
