The Problem with Psychology

The Problem with Psychology


As many undergraduate students point out, psychology is a very interesting subject. In fact, psychology is among the most popular majors chosen at colleges and universities. However, there are several problems with the way that psychologists obtain data that is later taught in introductory and even higher level courses in the discipline. The study of psychology depends in large part on research studies. As many who have taken research methods or quantitative methods courses know, random sampling is crucial in ensuring that results can be generalized to the general population. Notwithstanding, most psychological research is done with psychology students, often in exchange for course credit (or percentage points towards the final course grade).

Thus, the samples used in psychological research are often far from being random and are consequently difficult to apply to the general population. The problem has often been described in the academic literature. Furthermore, in one particular study consisting of three parts, the behavioural scientists found that even among students, those who choose to participate in studies differ significantly from those who do not. As such, there are three different orientations described in the peer-reviewed article: prosocial, individualist and competitor. Naturally, prosocials are more oriented to help others and act altruistically. Alternatively, individualists are more concerned with self-interest or “what’s in it for them”. Finally, competitors focus on the difference of outcomes between their own performance and that of others.

The study (conducted by Van Lange et al., 2010) shows that students exhibiting prosocial orientation were more likely to participate in research than the other two groups. The researchers further theorized that students with a prosocial orientation were perhaps more likely to choose psychology as a major in the first place, given the opportunity in the field to help people. Indeed, psychologists often help people in the clinical and other settings. Therefore, the problem arises as to generalizing the findings of psychological research to the general population. Perhaps, the wisdom gained shows human nature in a skewed way, mostly applicable to undergraduate psychology students with a prosocial orientation and is thus inadmissible evidence to the population at large.

Neurogenetics and Perception

Neurogenetics and Perception


The purpose of the present essay is a brief discussion of neurogenetics and sensation, perception and interpretation of sensory stimuli by the brain. Neurogenetics is a field that studies the genetics of the nervous system, and how genes might explain differences in genotypes, and resulting expressed phenotypes, in individuals. Naturally, the discipline draws on both genetics (the science of genes and related subjects) and neuroscience (the study of the nervous system).

Other interesting subjects are the steps of sensation, perception and interpretation of the five senses. Of most interest would be vision and audition. For instance, there are parallels between seeing and hearing. Photoreceptors react to light wavelengths and are located in the retina, the lining at the back of the eye. Two types of these sensory receptors exist: rods and cones. Rods are located on the periphery and are better suited to night vision. Alternatively, cones are concentrated on the fovea (full Latin name fovea centralis), possess better acuity and can discern colours. Due to lack of receptors at the location where the optic nerve leaves the eye, a blind spot is formed, where no vision occurs.

Further, in audition, there are likewise two types of receptors, or stereocilia: the inner and outer hair cells. The auditory receptors reside in the organ of Corti, and are thus sometimes called Corti’s cells. Signals thus obtained are similarly transmitted to the brain via a nerve bundle, namely the auditory nerve, auditory receptors are also vestibular. Finally, from there, the transduced energy is taken to the occipital lobe for vision, and the temporal lobe for hearing.

Positive Psychology

Attachment and Attraction


Jokes aside, a famous psychological study found that individuals with depression actually had a more realistic perspective on life, the glass being indeed half empty, at least in that particular experiment carried out by the researchers. Psychology is a social science and thus relies mostly on studies. Unlike physics or other ‘hard’ sciences, psychology cannot always be quantified using laboratory experiments and thus turns to naturalistic observation and social experiments to predict, describe and explain (goals of science).

Psychology has many branches, and two very opposite disciplines may be juxtaposed in the likes of positive psychology and abnormal psychology, mostly because abnormal psychology looks at disorders negatively impacting human lives, while positive psychology seeks to concentrate on the brighter side of life. To illustrate, Major Depressive Disorder, commonly known simply as depression to the general population, translates into a persistent state of low mood levels. Everyone gets the blues and it appears normal, particularly in reaction to a traumatic event, but in individuals with depression, the symptoms persist for more than two weeks, and include (list non-exhaustive):

  • sudden weight loss or gain
  • altered sleep patterns
  • suicidal or dark thoughts
  • loss of motivation
  • social withdrawal
  • loss of interest in any (and often all) activities once enjoyed

Internal, as opposed to external locus of control, has often been cited a a predictor of lifelong success, self-confidence and as a sort of protection against depressed mood. Internal locus of control is the belief that one influences the world and events in it (to a rational degree, not like ideas of reference in schizophrenia!), while external locus of control may be compared to fatalism. In addition, learned helplessness may be viewed as an extreme of this continuum, believing that no matter what one does, the effect will be the same. A word of caution, however. One of the definitions (non-scientific) of insanity is doing the same thing over and over again and expecting different results, so while persistence and positive thinking may be helpful at times, at other times changing strategy or giving up altogether may be the wise choice to make. Sometimes, it is just not meant to be, and one must accept reality as it is.

For the person suffering from depression, feelings of desolation, despair, loneliness and losing interest in everything, are common symptoms. Fatal in severe and extreme cases terminating in suicide, even mild clinical depression is a fairly serious and debilitating illness and demands professional attention.

The importance of faith and religion has often been portrayed in mostly non-academic literature, scholarly documents focusing mostly on science alone. Notwithstanding, negative thinking may preclude one from even hoping for, or believing in, anything, altogether. Again, this is one extreme, the other extreme being magical thinking, believing everything will go exactly as planned and as one wishes, simply because one wishes it so, which can translate into delusional thinking (delusions are a symptom of mental illness). Delusions are characterized by persistent belief in something which is clearly false, despite all other evidence to the contrary. Additionally, while it is normal for a child to believe in fairy-tales, it strikes others as odd when adults still hold the same mentality.

From a therapist’s perspective, it may not always be easy to cheer up a person with depression, especially if they themselves hold a cynical view of the world; humanity, after all, has a lot of flaws. For example, Stanley Milgram conducted studies about obedience to authority. The experiments focused on blind obedience to authority and the experimenters rationalized the shocking results (omitted from the present discussion) using the belief that nothing really bad could happen in an experiment. Another study showing a rather dark side of humanity, were Zimbardo’s prison experiments. Power corrupts – and absolute power corrupts absolutely. The famous quote, while debated, may be used to discuss Zimbardo’s prison simulation experiments, a psychological study turned so sour and dangerous, that it had to be interrupted for subjects’ safety sake. A movie based on the story portrays the events pretty accurately.

Psychological studies have shown that religious people tend to be happier. However, as usually is the case with correlations, it remains unclear whether religion makes people happier, or whether happier people tend to be more religious. Also, it may be that attending mass and being church (and therefore often community) oriented, leads one to an altogether healthier and more positive lifestyle, than, say, consistently hanging out at the local bar (not that the two are mutually exclusive).

Positive psychology dictates that how people view things significantly impacts their life outcomes. A similar point was brought in the somewhat esoteric book, and derivative movie, The Secret. The authors claimed that the ‘Law of Attraction’ acted almost like a genie (a magic creature granting wishes) and could warrant anyone anything she or he wanted, provided they thought about it in a certain way. While if understood simplistically, the tale seems a dangerous and misleading one, there is certainly some truth in that extreme negativity rarely helps matters.

Attraction versus rejection. Body language can convey a lot of messages, although these are often misinterpreted. For instance, a person with arms closed is said to be unresponsive to whatever is being proposed or discussed, but at the same time, that individual may simply be cold. 

Aside from positive psychology, other psychological fields, such as social as well as developmental psychology, look at the interaction between one’s emotions and disposition, and occupational, academic and romantic success. For example, theorists Erik Eriksson and Mary Ainsworth both believed that the amount of trust a person feels towards initially their primary caretakers, and then generally those surrounding them, influences the quality not only of their relationships, but of their lives in as a whole.

Popular Psychology

Popular Psychology


The pop psychology phenomenon refers to the popular interpretation anddemonstrations of the social science that studies the mind and behavior. In recent years, the practice has gained increasing popularity with relatedtelevision shows, such as Lie to Me orDr. Phil. While the methods do resemble, psychologists and pseudopsychologists do use surveysand other questionnaires, the scientific methodology is rigorously respected only inthe former. College and university students majoring in psychology often hear that the behavioral science is anomnipresent part of human life, day-to-day existence and operations, sincemost of us solve psychological dilemmas on a daily basis (e.g. how to let acoworker know they have a stain on their lower back, how to courteously let anemployee know that they ought to produce better work or how to humanely end anunpleasant relationship)…

Nonetheless, social scientists, researchers and experimenters have to follow explicitlyoutlined methodology, which remains ensured by a qualified peer review process. Without permissions granted by this commission and ethics committees, scholarlyauthors fail to be published. Still, other professionals deplore the flaws ofthe review mechanism, stating that within a narrow area of research, all tend toknow each other, and thus less than a hundred percent accuracy andobjectivity appear as a likely outcome. Objectivity (a disinterested, non subjective approach), reliability (dependability),generalizability (applicability to the general population), replicability(international colleagues must be able to replicate the findingsobtained) and validity (whether a test or experiment measures what it wasdesigned to measure) are among the most important qualities or criteria inresearch methods.

Black Creek Pioneer Village IV

The Black Creek Pioner Village, Part IV


The pioneer village consists of over forty 19th century buildings, decorated in the style of the 1860s with period furnishings. These rooms tell the story of first settlers. The interiors show the pleasing proportions of the Ontario classic style.

Located in the Visitor's Centre, the Black Creek Shop features a wide selection of historical books, souvenirs, handcrafted reproductions of 19th century household items such as lanterns, slate boards (the first computer ) and slate pencils, historical maps and newspapers of the period along with historic communities book series for ages 6 to 14.The Gift Shop also offers light snacks, beverages, and candies.The gift shop accepts Visa, MasterCard , Amex, and debit card.

And this old village brings on many thoughts.

(All the pictures have been taken by Elena).

To deny pain after a loss is to hold on it.

Only be experiencing the pain - to go through it, to feel it, to express it and speak about it - can we truly learn from it and be set free to move on.
We cannot avoid the hurt. We must learn to cope with and move into the pain.
Yearning... In the weeks and months following the death of a person you love, no matter what you were doing, you would find your mind wandering.
You may dine, but the person who you love and who left you will be in your thoughts constantly.
After a loss, you are emotionally and physically vulnerable, so it is strongly advisable to have a physical check-up by your doctor. (Doctor's House built circa 1830. Original Location: Chinquacousy (Brampton), Ontario. The verandah with its curved copper roof is a welcome entrance to this timber frame home with wood sheathing and stucco finish).
Your doctor will ensure your symptoms are not caused by a specific medical ailment. (The Doctor house was originally a farm house designed to accommodate two generations of the family at once).
Saying such symptoms may be normal does not lessen the fact that they may require attention. (Doctor's reception room: With two front doors, completely separate upstairs and doors to close off each wing, two families could live separately in the same home).
The death of someone we love can be one of the most agonizing experiences of life. (Doctor's reception room: This design made the house ideal for the village doctor. With one section of the house used as living quarters, the other section served as the doctor's office and waiting room).
After somebody dies, you experience many confusing and conflicting emotions. You are hurting. In fact, during that difficult time, everything seems to hurt. (Picture: Dominion Carriage Works).
Very few people enjoy pain. Most of us do everything possible to avoid it. And when we lose someone we have counted on for, we lose the confidence to face the world. We find ourselves struggling to cope with many unexpected and surprising emotions.
If we have a physical pain, we take a pill to try to get rid of it. And with the loss of a person we love, we can do nothing. Edgely Slaughter House, built circa 1860 Original Location: Edgely, Ontario (Jane Street and Hwy #7).
