Sigmund Freud and Psychoanalytical Theories

Sigmund Freud and Psychoanalytical Theories


Relationships have been studied by psychologists for decades. Sigmund Freud, the founding father of psychoanalysis focused on the sexuality aspect. Indeed, Freud pioneered psychoanalytical theories, which have largely been discarded today, and are mostly taught in psychology university programs for their historical value. Thus, Freud described psychosexual stages of development and believed that adults form relationships by resolving deep seated, subconscious psychological conflicts.

Conversely, Freud also described the Id, Ego and Superego. While the Superego is conscious, the Id is a subconscious, animalistic part of consciousness. The Superego tries to reconcile unacceptable desires of the Id with the Ego. Other Freudian theories include castration anxiety and penis envy. As the names indicate, these highly sexualized concepts refer to sex based psychological internal conflicts which centre on the fear of parental competition, and rejection of one’s gender, respectively.

Psychological Theories


Psychology is defined as the scientific study of the mind and behavior.

There appears to be some confusion as to which are the differences between a psychiatrist, a psychologist, a psychotherapist and a psychoanalyst. Despite widespread interest in the popular media, as evidenced by movies such as Analyze This (1999) and Analyze That (2002, both starring actor Robert De Niro), psychoanalysis has largely been eradicated.

Further, psychiatrists are doctors, thus, to practice psychiatry, a person must first complete medical school, and then specialize in psychiatry. A psychologist is not a doctor. Psychologists do not and cannot prescribe medication. In many jurisdictions psychologists must earn a Ph.D. (Doctor of Philosophy – second graduate degree, typically entered into after a Master’s degree) in psychology prior to be allowed to practice.

Alternatively, a psychotherapist does not need to study as much, since theoretically, almost anyone could potentially set up shop and act as a psychotherapist. Restrictions vary according to regions, and exceptions apply.

Sigmund Freud, an 19th century Vienna physician, is considered the father of psychoanalysis, and while his theories are still taught in psychological programs, few practicians remain in reality, as many psychoanalytical assumptions have been discarded. Freud’s concepts were contradictory, centering on sexuality (i.e. Oedipus and Electra complexes, penis envy in girls, explanation of vagina dentata, fear of castration in boys, etc.). Freud’s theories are believed to have been influenced by the sexually repressive context of the Victorian era.

Also, psychology is taught at most institutions of higher learning. Image: Copyright © Megan Jorgensen.

Nonetheless, Freud has also contributed to child or developmental psychology (the scientific study of the individual across the lifespan). Along these lines, the first known psychoanalyst developed a series of psychosexual stages describing growth and development. However, one must keep in mind that none of these have to do with the act per se, but rather how unconscious thoughts and instincts allegedly influence one’s mind. Freudian theories have been criticized extensively because of their strong emphasis on sex, and often sexist views.

Another notorious child psychologist was Lev Vygotsky, who introduced concepts such as the Zone of Proximal Development (ZPD) and scaffolding, arguing that children needed more experienced others and supervision in order to learn. An alternative view came from biologist Jean Piaget, who believed in innate cognitive abilities. Interestingly, many theorists (Freud, Erickson, Kohlberg, Piaget, Gilligan) separated growth into steps, according to ages.

Erickson suggested that at each psychosocial step a choice had to be made. Conflict to resolve in Erickson's psychosocial stages: 1) Trust vs. Mistrust 2) Autonomy vs. Shame and Doubt 3) Initiative vs. Guilt 4) Industry vs. Inferiority 5) Identity vs. Role confusion 6) Intimacy vs. isolation 7) Generativity vs. Stagnation 8) Ego integrity vs. Despair.  Image: Copyright © Megan Jorgensen.

Another prominent theoretical construct was proposed by Mary Ainsworth, who suggested various attachment styles, as assessed by the Strange Situation task. Attachment styles were defined as secure and insecure. The insecure category was further subdivided into anxious, avoidant and dismissive.

Apparently, aside from, logically, impacting one’s relationships in adulthood, attachment style may even carry repercussions on cognitive undertakings, such as academic achievement.

Onwards, although Ivan Pavlov refrained from calling himself a psychologist, but rather a physiologist (he did win the Nobel Prize for physiology in 1904), his experiments with dogs are some of the most famous studies in the field, and likely among the first topics presented in a learning and memory introductory level class. By the same token, classical conditioning is also known as Pavlovian conditioning.

The initial classical conditioning went as such: dogs salivate to food – the unconditioned or unconditional stimulus – US – terms used interchangeably in academic literature. However, Pavlov paired the US with the sound of a bell – or the conditioned or conditional stimulus – CS. Therefore, in time, the dogs started to salivate to the sound of the bell – or the CS. In the situation described, salivation to food is the natural, or unconditioned response – UR, while salivation to the bell sound is the learned or conditioned response – CR. The famous story of little Albert, who became afraid of white furry pets, rests on the same principle.

Later, behaviorism with such proponents as B. F. Skinner, and his work with pigeons, stole the limelight. Skinner developed such ideas as superstitious behavior and what became known as the ‘Skinner box’.

A deplorable fact of psychology’s dark past is experimentation with animals, which prior to stronger ethics and care committees, was at times cruel and absolutely unacceptable. Perhaps one of the worst incidents is perception research by Hubel and Wiesel, where the eyes of newborn kittens were sewn together. While that laboratory did find that neurons in the visual cortex would fail to progress properly without appropriate stimulation, one wonders if it is even possible to consider such knowledge as worthy of such inhumane treatment of cats. Today, celebrities such as voluptuous Pamela Anderson, and organisms such as PETA, fight against mistreatment of adorable creatures.

Naturally, psychology is also used in business. For example, psychological ideas help in situations involving cross-cultural communication. To illustrate, Japanese businesspeople may feel insulted if certain rituals are omitted, Latin American ones if small talk fails to precede commercial discussion, while in some regions of the Middle East, someone punctual may be perceived as lacking in self-worth.

Moreover, continuing on the subject of psychology, Albert Bandura’s research interests included such areas as television, violence, imitation and modelling. His famous experiment involving a Bobo doll, showed that children tend to see as role models, and thus imitate, adults. Additionally, there has been a study providing evidence that creativity dropped in a small rural town after television and computer games were introduced.

Furthermore, many (and ironically enough MIT or Massachusetts Institute of Technology, professor Sherry Turkle) worry that technology and social media may isolate individuals from one another. The academician wrote a book (Alone Together, 2010) on the subject, which she confessed on political satire show The Colbert Report (right after The Daily Show hosted by Jon Stewart on the Comedy Central cable channel) took her 15 years to write! Aside from scholar authorities, many deplore the inability of online virtual life to teach proper social skills and the loss of the once praised art of socializing.

Neuroscience & Neurogenesis

Neuroscience & Neurogenesis


Neuroscience (also called neurobiology) is the subdivision of psychology, as well as biology, dealing with the brain. Neuroanatomy is fascinating, but a complicated subject, indeed. In fact, the brain has been designated by neuroscientists as the most complex object in the world. Notwithstanding, goals of science include to explain, so…

The Brain at a Glance


The basic building bloc of the brain is the neuron or brain cell. Neural cells contain a cell body or soma, a myelinated axon (myelin is a fatty substance coating the axon, faciliating and speeding up transmission between neurons), button terminals and dendrites. Neurons are the messengers of the brain and ensure communication in the brain and the rest of the organism by release, absorption and reuptake mechanisms evolving in synaptic clefts (synapses are the space between neurons). Neural influence can be excitatory and inhibitory, and different neurotransmitters bring about diverse results. The main neurotransmitters comprise serotonin, dopamine, adrenaline, epinephrine and GABA.

The brain consists of two hemispheres (left and right) and four lobes (frontal, occipital, temporal and parietal). Three layers, the meninges, insulate the brain, under the rigid skull bone. Cerebral matter may be white (nerve endings) or grey (nerves). The corpus collossum is the main commissure separating the left from the right hemispheres. Interestingly, this fact was established through lesion studies with persons undergoing surgery for epilepsia. Indeed, a lot of neuroscientific and psychological evidence comes from cases, like the famous patient H.M. and the associated research on memory and the hippocampus. Laterality of function remains somewhat debated, but largely the left side has a more analytical and logical specialization, while the right one tends to be more abstract and artistic in orientation.



Similarly, numerous accounts in the literature provide correlations between neural substrates and behavioral, or emotional, reactions. As such, the amygdala has been linked to fear, anxiety and aversive emotional memories, the hyppocampus to memory and particularly spatial memory, the frontal lobe to executive function (planning, organizing, inhibition/self-control, decion-making), the occipital lobe to vision, the temporal lobe to hearing and so on…

Neurogenesis


Most teenagers in the West have at some point in their lives heard the expression: Don’t do drugs/Watch too much TV/Play too many video games/Drink alcohol – it kills brain cells. As it turns out, to an extent that may be plausible. For instance, a study on creativity published in British Columbia, Canada focused on creativity in youth in a small rural village both before and after modern media and telecommunications were introduced. Not surprisingly to outdoors protagonists, creativity went down. Further, psychology and biology professors do often stress the likelihood of chemical subtances, especially subtance abuse and dependence, to harm brain cells, but there’s more…

Apparently, depression, or more specifically Major Depressive Disorder and the accompanying serotonin (mood stabilizing neurotransmitter) depletion also detroys neural clusters. Alternatively, neurogenesis refers to birth of neurons, once when the cerebrum is formed (most die per design through natural, biological mechanisms such as pruning and apoptosis); and, in some cases later in adulthood (i.e. a study has demonstrated hyppocampal neurogenesis in laboratory mice who were put on an exercise regimen). In contrast, neuroplasticity relates to the ability and tendance of neurons to rerrange their functionality according to learned processes. Regardless, neuroplasticity is far beyond the scope of the present short paper.

Psychology, altough to a lesser extent neuroscience or neurobiology, have been criticized as social sciences, and thus not exact as, hard or pure and applied science. While the criticism certainly carries weight, rigorous, scientific approaches remain possible with appropriate research methodology – which is why most peer-reviewed articles in academic journals include a methods section, for other researchers to be able to understand and replicate obtained results. Along these lines, unlike physics and chemistry operating in the real world, behavioral phenomena is often best observed in laboratories, with carefully crafted experimental designs and animal models.

Psychology is a wildly debated field. Some believe it is a science, most define it as a social science or behavioural science, and yet others reject it completely calling it a pseudoscience. A very interesting field in psychology is social psychology. Many students enrol in social psychology classes out of pure interest. Indeed, social psychologists study the fun stuff: relationships, friendships, team work, social competence, popularity, peer pressure and so on. On friendship, usually social psychologists agree that friendships are formed based on proximity, similarity and mutual liking. Another key point is that friends often share similar interests.

Further, friendship is a very interesting concept. For example, some believe that real and true best friends can spend years without talking to each other and yet the friendship remains as solid as it ever was, if not more than ever before. However, others remain of the opinion that good friends are inseparable and always stay together. Of course, the way social psychologists would discuss these concepts is by first conducting a psychological experiment. Regardless of physical proximity (discussion of which is beyond the scope of the present paper), friends offer each other social and emotional support, as well as entertainment and access to word of mouth knowledge.

Indeed, most conclusions in psychology are drawn from experimental data. However, two points must be made regarding experiments. Well, at least two points… First, experienced psychology professors advise to be skeptical of any one study, it is always preferable that the results be replicated by at least one other team of researchers. Further, most psychological experiments are done with university students. For instance, many psychology classes offer a one point percentage credit in the term mark for participating in psychological research. The problem with this approach is that results thus obtained may not be generalizable to the general population. Thus, psychology studies have their limitations.

Social Psychology


As mentioned elsewhere in other posts, psychology is a social science subdivided into many branches, each studying the human mind and behavior from different perspectives. While neuroscientistists study brain anatomy (or neuroanatomy), social psychologists look at the interpersonal and interactive psychology of social events.

The Constitution of the United States of America, secures, among other things, the right to pursue happiness for individuals. But what is happiness? Clearly, the subject matter has constantly been debated by philosophers and artists alike, but medicine has also its take on the subject. The medical specialization related most closely to psychology is psychiatry. Unlike psychologists, who are usually required to have earned a doctoral degree and are thus Ph.D.s, psychiatrists are doctors in the sense that they are physicians, whereas psychologists are mental health professionals who treat conditions with psychotherapy, but tend to be forbidden from prescribing medication in most jurisdictions.

Both the American Psychiatric Association and the World Health Organization publish manuals designed to help diagnose mental illnesses and other psychological disorders for practitioners. Perhaps one of the better known such diseases is depression (depressive symptoms can manifest in a number of disturbances, including Major Depressive Disorder, Seasonal Affective Disorder, Dysthymic Disorder, Bipolar Disorder and Schizoaffective Disorder).

But what causes depression? Academic and institutional research on the issue in abundant. However, on the unscientific side, many people feel depressed or sad occasionally, it is the recurrence, persistence, intensity and duration of the symptomatology which may lead to a professional diagnosis. Clearly, if one suffers from dysfunctionality, there are a variety of sources of help, including family doctors, general practitioners, psychiatrists, hospitals, clinics, group support centres and other therapeutic establishments.

Several simple steps seem to contribute to good mood in general, in most individuals. To illustrate, a healthy lifestyle, eating a balanced diet and exercising, as well as a fulfilling vocational, in addition to a social and personal life, contribute to an end result of happiness. Still, even though physical activity releases endorphins (the body's natural feel good chemicals) and a spirit free from either eating disorders or health concerns associated with obesity appear to be good predictors of sustained contentment, other factors, such as quitting smoking or extensive stress (due to even positive changes!) may negatively impact one's disposition and mood.

People often turn to others in times of trouble, but depression is different in that respect. For example, while having a trusted circle of close friends and a large network of acquaintances facilitates social and emotional support from peers, persons with depression withdraw as a coping mechanism, which paradoxically, could then further exacerbate symptoms. As an extraverted but disappointed loner suggested - after using the "How to pick up girls in bars?" tips from a non-Scandinavian attraction schemes artist - loneliness acts as a downer… However, social psychologists argue that loneliness and solitude are two different concepts, with only loneliness implying dissatisfaction with the state of being alone.

Schizophrenia and Psychotic Illnesses

Schizophrenia and Psychotic Illnesses


A reason to hope

(Abnormal psychology or clinical psychology)

Schizophrenia and psychotic illnesses are treatable brain disorders. Unfortunately people are not always getting the help they need. A diagnosis reaches beyond the individual, it also impacts families and friends who can provide a crucial support network. Schizophrenia and psychotic illnesses are truly a community illness and demands a community response.

Education and awareness remain the key to ending stigma, because stereotypes and misinformation are prevalent and can stand in the way of people living the full and meaningful lives they deserve. We really can dispel myths and improve the lives of millions of individuals.

Myths and facts about schizophrenia:

Myth: Schizophrenia is a rare illness, it could never happen to me.

Fact: One of 100 people will get schizophrenia, and many more individuals have psychotic disorders bordering with schizophrenia. It can happen to anybody.

Myth: People with schizophrenia are dangerous and violent.

Fact: People with schizophrenia are more likely to be victims of crime than commit one.

Myth: Schizophrenia happens to older people only.

Fact: Young people are most of risk, with onset of schizophrenia typically happening between 16 and 24 years of age.

Myth: People with schizophrenia look and act very differently.

Fact: Symptoms are not always visible. People with schizophrenia can look and act just like anyone else.

Signs and symptoms

Symptoms of schizophrenia and psychotic illnesses often develop slowly over month and even years; with onset typically occurring during early adulthood and late adolescence. Symptoms of schizophrenia in particular are split up into three categories positive symptoms, negative symptoms and thought disorder.

Signs of positive symptoms, such as hallucinations or delusions, can include:

  • Talking aloud to yourself;
  • Seeing of hearing things that are not apparent to others;
  • Suspiciousness;
  • Fear that someone is trying to harm you.

Signs of negative symptoms, such as depression and social withdrawal, can include:

  • Lack of energy or interest in life;
  • Loss of motivation…

Signs of thought disorder, such as disorganized or racing thought, can include:

  • Speaking incoherent manner;
  • Losing your train of thought;
  • Jumping from one topic to another.

Diagnosis of schizophrenia or a psychotic illness changes so many lives. It touches not only a person with a diagnosis, but all the important people in their lives. It`s truly a community illness, and it demands a community response.

Education and awareness remain the key to ending stigma, because stereotypes and misinformation are prevalent and can stand in the way of people living the full and meaningful lives they deserve.

The Best of Friends

The Best of Friends

By Dr. Megan Jorgensen


Lucky I’m in love with my best friend – Jason Mraz and Colbie Caillat

As apparent from songs’ lyrics, movie features and anecdotal stories, every day life may be enhanced, while hardships lightened, by friendship. Indeed, belongings considered a formal human need, while peer pressure is responsible for many an unpleasant decision, especially in more vulnerable persons. Along these lines, the social scientists looking most closely at such interpersonal interactions are social and personality psychologists.

Indeed, social psychology theory states that people tend to form bonds with those closest to them (proximity), alike themselves in intelligence, interests,background and values (similarity), as well as, emotional ties and intimacy (liking). Together, these three principles may very well be responsible for tales of life long relationships involving companionship, trust, self-disclosure,humor and a lot of fun.

Close friends, similar to old, happily married couples, are rumored to understand each other without words. Does the association stand only for a romantic dyad or lovers? In effect, while cross-cultural studies have shown that persons across the world recognize facial displays of basic emotions, closer friends may be better apt to read these, than casual acquaintances, according to a paper by Zhang & Parmley (2011). In fact, familiarity with idiosyncrasies of expression may help emotional decoding. Notwithstanding, the link appears stronger in relation to subdued rather than high intensity affect.

Alternatively, DeScioli et al. (2011) describe how reciprocity plays an important role informing and maintaining social ties. The authors mention the alliance hypothesis,stating that allies represent a buffer against potential disputes. However, the partner to be must prefer one to an opponent in a conflict situation. In support of the postulate,individuals’ rankings of other users in their public Internet profiles corresponded to how these alter egos ranked them in turn.

In conclusion, friendship patterns differ between individuals. To illustrate, psychological research documents that these are evident as early as the first school years,when some youngsters, deemed most popular, form several superficial acquaintances hips, while others vary from rejected, aggressive and lonely, to content with few but closer, deeper and more meaningful friendships. Clearly,in the digital era, social interaction has been greatly impacted by the advent of online networking Websites.
