Behavioural genetics Essays

1.1 Background of the Study Since the publication of book entitled Frames of Mind by Howard Gardner in 1983, the concept of Multiple Intelligences (MI) Theory brings the new horizon in Psychology and Education. The traditional view of intelligence was best conceptualized as a single, general capacity for conceptualization and problem solving which simply measured by the IQ (Intelligence Quotient) test. In addition, Spearman (1904) as cited in Bandarabbasi, & Karbalaei (2013) claimed that there is

Introduction People who guide and interact with the children must have the basic knowledge of their overall personality development from birth to puberty. So especially parents must know how to guide their children, and should have a basic knowledge of the development of sexuality from infancy to adolescence. Freud (1964) believes that children’s pleasure is governed by the id and are focused on a different area of the body (Erogenous zone) at each stages of development: oral, anal, phallic

(“Nature-Nurture Controversy”). This idea can be proven in Mary Shelley’s Frankenstein through the development of the Creature. The Creature was created with no reference to his genetics or ancestors. The reader cannot predict the Creature’s genes because the reader is not given any information on where the Creature’s genetics come from. The Creature notices his lack of family from early in his existence. The creature is without family to raise him and nurture him. The Creature reflects on this, saying

“‘But not us! An’ why? Because … Because I got you to look after me, and you got me to look after you, and that’s why,’ [Lennie] laughed delightedly ” (Steinbeck 14). My guess is, you probably recall this quote from John Steinbeck’s, Of Mice and Men. What you may not remember are the underlying themes hidden within his novella. Before you disregard this letter as another one of my rants, let me explain. As you may know, Steinbeck was known to use his platform as a writer to represent the struggles

Memories in the Human Brain When we recall memories, the brain “replays” a pattern of neural activity. These replays are not exactly the same to the original memories. Otherwise we would not know the difference between genuine experience and the memory. The human brain is divided into different parts that store and retrieve memories. How do we recall and store memories inside the brain? To store memories, information flows from the outside world through our five senses. Memories are not stored

Psychology can be primarily defined as a type of science. It is the science that encompasses all aspects of the mind especially with regards to thought, conscious and unconscious events as well as behaviour. It is studying the various processes that occur mentally which relate these activities to the brain in terms of intelligence, perception, emotion etc. Psychology is the main field of study having subdivisions that allows individuals to focus on and specialize in an area of psychology such as

The notion of the nature nurture debate is an ongoing argument that deliberates the views of development and their influences. This debate questions whether genetics or the environment surrounding a child has greater influence on development. It is necessary to highlight a variety of current and popular opinions in regard to the debate to determine differences in perception and research and the greater influence in development. This essay will discuss the concept of nature and nurture, then the perceptions

Plomin, R. (2014) G is for genes. Chichester, West Sussex: John Wiley and Sons. An insight into the field of behavioural genetics, how genotype can affect children’s ability to learn and how application of this knowledge within the educational system are factors that could ensure fulfillment of every child’s potential. Information within this text can assist in understanding more about how genetics influence child development. Further content in the book covers aspects of how nurture, environment and

From the primary literature, briefly summarize two studies that have used Drosophila as a model organism in a genetic or evolutionary context (Twenty Five Marks). The aggressive behaviour of the Fruit flies (Drosophila melanogaster) have been observed in a study to see the reaction of various neurobiological factors. Several techniques are used in the study including behavioural and genetic techniques. In the brain of the Drosophila melanogaster, neurotransmitters dopamine and octopamine as well as

called deoxyribonucleic acid (DNA). The DNA contains the instructions for producing proteins; it is these proteins that regulate the development of a human being. Although half of your chromosomes come from your mother and half from your father, your genetic pattern can be different from the patterns of either of your parents. Your genes determine who you are, for example they determine your

diseases are governed by our genes. Other physical attributes if not determined, seem to be strongly linked to the genetic makeup of our parents. Height, weight and life expectancy are all correlated between related individuals. This has led many to speculate as to whether personality traits can also be inherited. People have speculated if psychological characteristics such as behavioural tendencies, personality attributes and mental capability was ‘wired in’ before

The biological approach believes us to be as a consequence of our genetics and physiology. Physiology is how the nervous system and hormones work and how the brain functions. It examines how changes in structure and function can affect behaviour. The Biological; approach examines thoughts, feelings, and behaviours from a biological and physical point of view. An influence within the biological approach is genetics, characteristics that are not suited to a species’ environment will die out as it struggles

INTRODUCTION NATURE This refers to all the evolutionary factors that have that have shaped the genetics that we inherit from our parents. Nature determine the range of our human potential.Naturists believe that the knowledge humans have about the world is innate. Therefore human development is largely determined by heredity. NURTURE This refers to all the things that have influenced us since we began to grow. Nurture affects the way our human potential is actualized. Empiricists believe that is the

Introduction The origin and evolution of the domestic dog is a rather ambiguous one that is highly debated amongst evolutionary anthropologists. Many question the extent to which domestication has influenced the evolution of the domestic dog due to the ever growing information palaeontologists are discovering. My intent is to examine the theories proposed by palaeontologists and evolutionary anthropologists to see to what extent domestication has influenced the evolution of dogs, taking into account

lifespan. Biology and Evolutionary Theories emphasize that the factors that motivate human behaviour are both genetic and biological process, and that they have gradually changed over time through a process of genetic mutation, natural selection, and evolution (Bee, Boyd, & Johnson, 2018). Associated with these theories are the study of genes, patterns of inheritance, behaviour genetics, ethology, evolutionary psychology, as well as the work of influential evolutionist Charles Darwin, who believed

Prader-Willi syndrome is a rare genetic disorder, that affects development and growth. It is estimated that 1 in 15,000 people ae born with PWS. Girls and boys are both equally affected. There is no cure for the disorder, however professional heath care can improve the child’s quality of life. Prader-Willi syndrome is a life long genetic disorder, where seven genes on chromosome 15 are deleted. People who suffer from PWS may have physical, mental and behavioural problems. The main one being unable

freckles from your father but where did you get your thrill-seeking personality and talent for singing? Did you learn these from your parents or was it predetermined by your genes? While it's clear that physical characteristics are hereditary, the genetic waters get a bit more murky when it comes to an individual's (Powell, K., 2006 March 15). The idea of nature is the hereditary traits and the genes of a person that what he or she inherits from his or her biological parents like for example the height

offering a different explanations, approaches and interventions. The Diseased/Medical/Biological model has the belief that mental abnormalities are caused by biochemical, physiological or genetic causes, and therefore, treatment is through medical procedures such as drug therapy, ECT or brain surgery. Genetics studiessuggest that mental health problems are inherited from parents and there is evidence to support this. Neuroimaging states that structural changes in the brain can cause mental illness

malfunctions around the area), heart, and the kidneys (underdevelopment or absence of kidneys). Shorter stature and insufficient levels of growth hormones are a common symptom as well. Rarer malformations can effect almost every other organ. Behavioural problems can occur, but are not characteristic of CES. Mild to severe mental impairment is rare for patients suffering CES, but not

Jean Piaget developed the theory of genetic epistemology (cognitive development). 1Jean Piaget identified himself as a genetic epistemologist, which is the study of the origin (genesis) of knowledge (epistemology). Close Panel His theory suggests that our roots of knowledge, from elementary form, all the way through to scientific knowledge, progresses through stages. 2The four stages are, Sensorimotor Stage (birth to 2 years), Pre-Operational Stage (2 to 5 years), Concrete Operational
