THEORIES OF HUMAN DEVELOPMENT

THE PSYCHOANALYTIC VIEWPOINT

• Freud’s Psychosexual Theory
– Unconscious motives are repressed
– Development is a conflictual process
• Sexual and aggressive instincts that must be served, yet society dictates restraint

THE PSYCHOANALYTIC VIEWPOINT

• Freud’s Psychosexual Theory – Three Components of Personality
• Id: satisfy inborn biological instincts, now
• Ego: conscious, rational, finds a realistic means of satisfying instincts
• Superego: seat of the conscience, develops between ages 3-6 as morals of parents are internalized

THE PSYCHOANALYTIC VIEWPOINT

• Freud’s Psychosexual Theory
– Stages of Psychosexual Development
• Sex instinct, broadly defined, was most important • Focus of sex instinct shifts during development – shifts = stages
• Fixation – arrested development due to excess or a lack of gratification of needs

    While Freud theorised that children who smoothly transition through the stages grow to be calm, well centred adults, he felt that an unsuccessful completion meant that a child would become fixated on that particular phase and either over or under-indulge throughout adulthood. Believers of Freud 's theories on child development, then, must surely make every effort to help their children through each of the stages, allowing each child to experience their feelings without guilt or excessive pressure to conform to preconceived ideas…

    First, Pavlov used soundproof lab because it allowed to isolate experimenters from all extraneous stimuli during the experimental procedures. Second, Pavlov chose food as unconditioned stimulus because food will elicit the unconditioned response, which was the salivation of the dog. In order to find a neutral stimulus that was completely unrelated to food, Pavlov decided to use the metronome as the neutral stimulus . The ticking of the metronome was exposed to the dog, immediately followed by the food. After numerous trials under this condition, the dog has began to salivate after hearing the ticking of the bell. In another word, the metronome has changed from neutral stimulus to conditioned stimulus , which has created the conditioned response of dog's salivation. Pavlov and his assistants also elaborated on this preliminary finding by using different unconditioned and neutral stimuli. For example, the odor of vanilla was presented after a mild acid solution (similar to lemon juice) was placed in the dog's mouth . The mild acid solution caused the dog to salivate . However, after several trials, the dog began to salivate solely to the odder of vanilla . Another importance finding was that the neutral stimulus did not affect the subjects conditioning if it was presented after the unconditioned stimulus. Pavlov first gave the mild acid solution to the dog; and after awhile, presented the odor of vanilla . But there was no significant change of the dog's behavior. The odor of vanilla did not changed to a conditioned stimulus. he theory of Classical Conditioning (aka Pavlovian conditioning) has now been accepted universally and unchanged since its first finding through Pavlov's work. It is now used to explain various different human behaviors, such as causation of phobias, why people dislike certain food, source of emotions, etc. Pavlov's finding has showed that classical conditioning focuses on reflexive behaviors,…

    The ‘father’ of psychoanalytic approach is Sigmund Freud. Freud believed that human personality has a structure and develops over time. He proposed three parts: the id – in which the libido (an instinctual sexual drive) is centered; the ego – a much more conscious element that serves as the executive of the personality; and the superego – the center of conscience and morality, incorporating the norms and moral structures of family and society. In Freud’s theory, these three parts are not all present at birth. The infant and toddler is all id, all instinct, without the influence of the ego or the superego. The ego begins to develop in the years from age 2 to about 4, as the child learns to adapt some individual behaviours. Finally, the superego begins to develop before school age, as the child incorporates the parents’ values and cultural traditions. Freud also proposed the stages of psychosexual development. In each stage the libido is invested in that part of the body that is the most sensitive at that age. In a newborn the mouth, lips and tongue are the most sensitive parts of the body. The stage is therefore called oral stage. As neurological development progresses, the infant develops more sensation in the anus (hence the anal stage), and later in the genitalia ( the phallic and eventually…

    With child abuse cases on the rise, children are being used as evidence in the courtroom; this involves them giving accurate eye witness testimony. Parker and Carranza conducted a laboratory study in 1989 to study the accuracy of age in eye witness testimony. They showed a mock crime scene video to a sample of primary school children and a sample of college students. They found that the primary school children were more likely to ‘just pick’ a criminal from a line up compared to college students who were hesitant about choosing anyone but they were more likely to identify the correct person; concluding that adults were more likely to give accurate eye witness testimonies. On the other hand though Ceci and Bruck completed a study that concluded children may have more accurate eye witness testimonies as they have no prejudices or schemas. They don’t stereotype people and are more likely to tell you it ‘how it is’. The lack of a schema in children means that they can sometimes be more useful than adult eye witness testimonies as they have no preconceptions of the crime/incident. Goodman and Schaff showed that the language used when asking a child a question may affect a child’s recall because of their level of understanding and word development. Overall it has to be said that children give a less detailed EWT but this doesn’t mean that it is any less accurate. Young children are more prone to leading questions and are more likely to change their answer if a question is repeatedly asked because they feel they need to impress someone and the judge is ‘correct’ on comparison to them.…

    Exaptation: A variation of adaptation. An adaptation is a core construct in evolutionary psychology, which is a characteristic that a species has that promotes its survival. An exaptation is something that arises from a characteristic that you already have. A characteristic that you have is modified to promote your survival. It might not have been a primary future, but it is a characteristic that human beings have acquired over time that humans have used to their advantage. For example, the ability to reject an offer is an exaptation that people have made over time, which people have benefited from.…

    Psychoanalytic theories- theories proposing that development change happens because of the influence of internal drives and emotions on behavior. This originated Viennese physician Sigmund Freud (1856-1939) (Page 24: Lifespan Development). Psychoanalytic theorists believe that developmental change happens because internal drives and emotions influence behavior. According to Sigmund Freud, personality develops through a series of stages in which the energies of the id are focused on certain erogenous areas. This psychosexual energy, or libido, (roughly translated as sexual drives or instincts) was described as the driving force behind behavior. It consists of five separate phases: oral, anal, phallic, latency, and genital. In the development of his theories, Freud 's main concern was with sexual desire, defined in terms of formative drives, instincts and appetites that result in the formation of an adult personality. He also argued that personality has three parts: id, ego, and superego. Id is the part of the personality that compromises a person’s basic sexual and aggressive impulses; it contains the libido and motivates a person to seek pleasure and avoid plain. Next, ego states the thinking element of personality. Last, superego states the part of personality that is the moral judge. (Page 24: Lifespan Development). The ego is responsible for keeping the three components of personality in balance. Many of Freud’s patients had memories of sexual feelings are important to personality development. Based on his patients’ childhood memories, Freud proposed a series of psychosexual stages. The psychosexual stages of personality development through which children move in a fixed sequence determined by maturation. Examples of the theory are: oral phase, anal phase, phallic phase, latency phase, and genital phase.…

    Freud and Erickson state that human beings, starting at infancy through adulthood pass a series of psychosexual and psychosocial stages of development. The stages that will be discussed will be a combination of Freud and Erickson oral, identify vs. role of confusion, and phallic stages. There are six stages that Freud elaborated on but the first six years occurs in three stages each characterized by psychosexual pleasure center on difference parts of the body. However, Erikson’s stages differ significantly from Freud’s in that they emphasize family and culture, not sexual urges. He called his theory epigenetic, partly to stress that the expression of genes, as of biological impulses, is powerfully influenced by the social environment (Berger, p. 19, 2010).…
