During the first two years of infancy, there are constant changes in the height and weight of the infant. Because no child is the same, there are percentiles that indicate whether a child is growing appropriately. Children grow taller and proportionally thinner between the ages of two and six, and the variations between children depend on genes, nutrition, income and ethnicity. Motor skills are the learned abilities to move some part of the body and there are two categories: fine motor skills and gross motor skills. Fine motor skills are the physical abilities involving small body movements, especially of the hands and fingers while gross motor skills are physical abilities that involve large body movements, such as walking and jumping. Dancing, drawing and building are fine motor skills that help in the gradual mastery of …show more content…
The dendrite is a fiber that extends from a neuron and receives electrochemical impulses transmitted from other neurons via their axons. A synapse is the intersection between the axon of one neuron and the dendrites of other neurons. Pruning is the process where unused connections in the brain atrophy and die. Pruning of underused and unconnected dendrites begin in the sensory and motor areas of the brain and then occur in other areas. Some brain development is maturational, but experience is also necessary for development, and there are two different types of brain functions that come from experience. Experience-dependent brain functions depend on particular, variable experiences and may or may not develop in a particular infant, while experience-expectant require certain basic common experiences in order to develop normally. During early childhood, myelination is found in several crucial areas of the brain and as impulsiveness and perseveration decrease, children are able to learn more

Love

...CHAPTER I THE PROBLEM AND ITS BACKGROUND INTRODUCTION Nowadays, teenage relationship is common. You would see teenagers holding hands in the amusement parks, corridors and even public vehicles. It almost became a trend in the teenage world. More often, relationship status becomes a statement in the popularity of a person, and the aliveness of one’s life. College life may serve as a challenging chapter of life to every student. College used to face different forms of life, like different struggles to face in a day to day basis. This is the age where the transitional phase in every student happens, in which time management is hard to handle. Many college students are involved in a romantic relationship, but involvement to this may just cause more stressors to handle. Studying is toxic and very exhausting, sometimes escaping from stress and relaxation is what a student is looking for. Teenagers look for moments where they can feel free and love. The feeling of love remedies the toxicity of what a student is experiencing. It lets a person escape from reality and live by its fantasy. But imagination just only brings happiness; people still live in reality thus resulting to poor performance. Thus, it definitely depends on the person who’s handling it. According to the study made by Matthew Kopfler, it says that, “Students in relationships tend to have a higher stress level when meeting deadlines on assignments and completing school work, but...

Psychoanalytic Approach to Personality

...conscious and unconscious factors of the brain. Psychoanalysis is a form of psychotherapy for patients who have mental problems. This paper will provide thoughts on Freud, Jung and Adler’s theories on characteristics of personality. Psychoanalysis has three means the first is exploring the human mind, the second is treatment of psychological problems and the third is to understand human behavior better. In exploring the different theories of Freud, Jung, and Adler this paper with compare and agree and disagree with characteristics of research done by the three psychologists. In Freud’s theory an explanation of stages and characteristics of personality of the components used will be described. An understanding of at least three of Freud’s defense mechanisms will be offered in explanation with examples of real-life events. Psychoanalytic personality Assessment The theories found between physiologist Freud, Adler and Jung were interesting when all of the research is compared. Each psychologist spent years doing scientific research on physics, medicine and laboratory research in understanding human behavior and personalities. After comparing information each man’s theory was similar yet different. Freud’s personality theory is based on ego, superego, and the unconsciousness of human behavior, for example impulse, wishing, desires, instincts, and dreams. Freud analyzed five stages of personality development that includes oral, anal,...

Lifespan

...lifespan is from the moment of conception through death. Lifespan development is the different stages a person passes through as he or she develops. Perspective of lifespan development understands the changes that occur in development. Freud and Piaget have very different theories of lifespan development. Freud’s theory is a basis of id, ego, and superego, whereas Piaget’s is a cognitive development that occurs over a person’s lifetime. Nature and Nurture are more than perspectives in lifespan development they influence how and who a person will be. Lifespan development is the time from conception to death as a person develops and grows; the perspective in relationship to human development is lifelong, and theories of lifespan development can be seen in Freud, and Piaget, while the influences of a person life is nature and nurture. What is Lifespan Development A person’s lifespan begins as a fetus and as it develops and grows for nine months in the womb becoming a person either male or female will continue through stages in a his or her life. The study of human development is a science seeking to understand how humans change over their lifetime (Berger, 2008). The changes a person goes through as he or she grows can be linear-gradual, predictable, steady, but normally they are none of these. The common stages are birth, infancy, adolescence, adulthood, old age, and the ending death. To define lifespan development is also to mention that humans in their lifetime learn to communicate...

Psychology

...Brain imaging techniques Introduction to brain imaging techniques and other methods A number of techniques are available to investigate the question of how and where in the brain particular perceptual and cognitive processes occur. Tasks or tests can be devised that place varying levels of demand on the cognitive, sensory or motor capacities of the participant being tested. Performance of these tasks is then correlated with physiological measurements, and on the basis of these results, we may go on to ascribe functions to areas of the brain. Whilst there is a growing fascination with imaging techniques in the popular media (e.g. ‘This is your brain on politics’), it’s important to bear in mind that each technique has limitations that often don’t get picked up on by newspaper editors who themselves have little-to-no experience using them.  The most often overlooked limitation is the issue of ‘reverse inference’ – just because cognition X (e.g. using one’s memory) is associated with brain activation Y (e.g. activation in the prefrontal cortex), that doesn’t mean that if a participant displays activation Y, they are necessary engaging in cognition X. Below we highlight some key neuropsychological and neuroscientific techniques, and a few of their limitations.  There are also a number of great blogs that deal with issues relating to neuroscience, particularly in the popular press (e.g. Bad Science, The Neurocritic, [citation needed]). Testing brain damaged subjects (Neuropsychology) ...

Language Acquisition

...Aspects of the Theory of Syntax, in 1964, his theories are now generally accepted as largely true. As a consequence, he was responsible for the emergence of a new field during the 1960s, Developmental Psycholinguistics, which deals with children’s first language acquisition. He was not the first to question our so far mute acceptance of a debatable concept – long before, Plato wondered how children could possibly acquire so complex a skill as language with so little experience of life. Experiments have clearly identified an ability to discern syntactical nuances in very young infants, although they are still at the pre-linguistic stage. Children of three, however, are able to manipulate very complicated syntactical sentences, although they are unable to tie their own shoelaces, for example. Indeed, language is not a skill such as many others, like learning to drive or perform mathematical operations – it cannot be taught as such in these early stages. Rather, it is the acquisition of language which fascinates linguists today, and how it is possible. Noam Chomsky turned the world’s eyes to this enigmatic question at a time when it was assumed to have a deceptively simple explanation.      Furthermore We are going to describe the stages in child language...

...Face recognition is a biometric technique that uses computer software to determine the identity of a person. It is used to verify a person from a digital image or video frame. In facial recognition the selected facial features from the image are compared with a facial database. It is used in security systems. Recognition is important in human beings as it helps in identification of people, and acts as a social tool. It helps in identification of people to socialize with in the society (Rakover &Cahlon, 2001). Using facial recognition people are able to identify who to socialize with, or who not to socialize with in the society. This is because people use facial recognition skills to socialize, and survive in the society. For example, men are able to identify the women to socialize with, or establish relationship with. This helps in increasing population in the society. Facial recognition is also shown by the relationship between the mother, and the child (Rakover &Cahlon, 2001). The bond is strengthened through facial recognition. Facial recognition also helps in communication. This is because through facial recognition one is able to portray his emotional status. The emotional status serves as a means of communication. There are several processes involved in facial recognition. Cognitive processes are the main process involved in facial recognition. The cognitive process helps in storage of information in long term memory and retrieval of information. The cognitive process helps...

Psy Consciousness

...7: States of Consciousness CHAPTER PREVIEW Consciousness is our awareness of ourselves and our environment. Conscious information processing enables us to exercise control and to communicate our mental states to others. Beneath the surface, unconscious processing occurs simultaneously on many parallel tracks. Our daily schedule of waking and sleeping is governed by a biological clock known as circadian rhythm. Our sleep also follows a repeating cycle. Awakening people during REM sleep yields predictable “dreamlike” reports that are mostly of ordinary events. Freud’s view that dreams can be traced back to erotic wishes is giving way to newer theories, for example, that dreams help us process information and fix it in memory or that dreams erupt from neural activity. Studies of hypnosis indicate that, although hypnotic procedures may facilitate recall, the hypnotist’s beliefs frequently work their way into subjects’ recollections. Hypnosis can be at least temporarily therapeutic and has the potential of bringing significant pain relief. Hypnosis may be an extension both of normal principles of social influence and of everyday splits in consciousness. Psychoactive drugs also alter consciousness. Depressants act by depressing neural functioning. Although their effects are pleasurable, they impair memory and self-awareness and may have other physical consequences. Stimulants act at the synapses by influencing the brain’s neurotransmitters. Their effects depend on...

Socialization over the Life Course

...and feeling. It is weird to say that we start socializing from children. We started learning things from others when young and most people continue their social learning throughout their life unless they are mentally and physically disabled. These might affect their social process when they begin to develop their skills. Socialization is also a matter of nurture rather than nature. Through socialization, individual also can understand other people and us as well. In contrast, socialization is a complex, lifelong process. There are six well known researchers that have made lasting contributions to the understanding of human development: Sigmund Freud, Jean Piaget, Lawrence Kohlberg, Carol Gilligan, George Herbert Mead, and Erik H. Erikson. There have been five different types of socialization, primary socialization, secondary socialization, developmental socialization, anticipatory socialization and re-socialization. In primary socialization, family is the only one that takes place. The family is usually the first setting of socialization and has the greatest impact on attitudes and behavior. For secondary socialization, there are few...

What constitute criminal behavior Criminal behavior is a behavior in which the offender commits an offense that has been deemed as being unlawful act and punishable by the government and usually it is against individuals or property. Criminal behavior is seen as being prohibition or possession that constitutes a menace against the general public or society. In hope of confining and understanding criminal behavior researcher begin to study the brain of violent crime and compare their findings to the brain imaging “normal” individual. Through doing this they came up a new field of study called neurocriminology. Adrian Raine has studied the brain image of murders, violent criminals and psychopaths and from this research, he is convinced that there is a social and environmental cause to violent behavior. Although he is also convinced there exist a biology side of this type of behavior (npr.org, 2013). Believing that just as it is a biological reason for schizophrenia and anxiety disorders and depression and there exist biological recidivists violent offending.

Behaviourists Explain Maladaptive Behaviour in Terms of the Learning Principles That Sustain and Maintain It

...: “ BEHAVIOURISTS EXPLAIN MALADAPTIVE BEHAVIOUR IN TERMS OF THE LEARNING PRINCIPLES THAT SUSTAIN AND MAINTAIN IT. DISCUSS THIS STATEMENT AND SHOW HOW A BEHAVIOURIST’S APPROACCH TO THERAPY IS IN STARK CONTRAST TO A PSYCHOANALYTIC ONE” Behaviourism is a movement within psychology that works on the principle that all behaviour is “learned” , that we were all born with a “blank slate”. Behavioural approaches use strict experimental measures to study observable behaviour ( or responses ) in relation to the environment, thus resulting in the maladaptive behavioural approaches that we employ to deal with our learning. Behaviourism was first developed in the early 20th century by an American psychologist John B Watson, who at the time was working in the field of animal psychology. He believed that all behaviour was observable and therefore scientific, and worked on the principle and study of the association between a stimulus and response. ( Watson did not deny the existence of inner experiences, but insisted that they could not be studied because they were not observable ) Watson’s stimulus and response theory of psychology claimed that all complex forms of behaviour – emotions, habits etc – are seen as composed of simple muscular and glandular elements that can be observed and measured, and that emotional reactions are learned in much the same way. Watson aimed to prove his beliefs with laboratory experiments, and one of these experiments was known as “ The Little Albert Experiment”...

Psychologists' Compare and Contrast

...Psychologists' Compare And Contrast – Jean Piaget & Sigmund Freud Similarities and differences Jean Piaget was a philosopher and developmental Swiss psychologist who is widely known for the epistemology studies relating children. Piaget’s theory of epistemology and cognitive development are both referred to as genetic epistemology.  Jean Piaget’s specific concern was on cognitive or intellectual development of a child and manner in which minds progress and process knowledge. Piaget’s fundamental thesis was based on the fact that children’s first grow theories of self-centric about the environment they are living in or about persons and objects in that environment. Secondly, children normally base the theories on the personal experiences that they go through while interacting with objects and persons in the environment. Thirdly, the child uses ‘Schemas’ in order to master or gain information regarding the environment. Lastly, sophistication of any child cognitive structure intensifies as a child develops as it did with a child’s schemas.  A child’s schema is a tool case of responses and actions to make things happen, initiating with rudimentary connections like grabbing or mouthing items and finally progress towards extremely sophisticated skills like scientific observation. Sigmund Freud, an Austrian neurologist, is the naissance father of the process of psychoanalysis. Sigmund Freud’s main concerns were psychoanalysis which is a clinic...
