IQ | What does someone’s IQ say about them?

Standard

I previously talked about how scores on an IQ test are developed, and what they mean mathematically. Now, I’ll look at what they can mean for individuals.

IQ could be described as the BMI of the mind. Although both numbers can provide useful information for a typical mind or body, they should still be regarded with caution especially in an atypical mind or body. BMI is near-useless for athletes, who will often score as overweight or obese due to their increased muscle mass. Similarly, IQ measurements may be helpful to understand a neurotypical person in a familiar situation, but they are flawed for people with neurodevelopmental disorders, or people who are unfamiliar with standardised testing.

3) IQ tests cannot always measure someone’s ability accurately. Health conditions and neurological differences result in people having uneven patterns of ability, which confuse IQ tests.

IQ | How do IQ tests work?

Standard

The Intelligence Quotient- or IQ- is one of the most popular subjects in psychology. Yet despite us often using IQ as a shorthand for intelligence, and even using it to define others, misconceptions about IQ are often louder than explanations.

So how do IQ tests work, and what does an IQ score mean?

1) An IQ test does not directly measure your ability. It uses maths to estimate your ability in relation to other people.

Revisiting Faith

Standard

A long time ago on a website far, far away (sorry Blogger.com!), I used to write about faith. I haven’t done that for a while- things got complicated, I left my church, and after that, bringing the subject up felt disingenuous. Explaining my perspective felt difficult; just saying either “Christian” or “non-Christian” wasn’t true, while saying “ex-Christian” implied a grudge or enmity which didn’t exist. I’ve since deleted the entirety of that blog from the internet, which may have been a bit hasty in retrospect. But I recently read part of a book which made me think about the subject again.

When I was a psychology student and in my “learn everything about Christianity” phase, I found a book called “The Integration of Psychology and Theology”. Then I forgot to ever read it. By the time I eventually started reading the book, it logically shouldn’t have meant anything to me. But I found a lot of value in how the book was written and how it approached both topics.

Integration…  does exactly what you would expect; it talks about why people perceive conflicts between psychology and theology, and whether these conflicts can be overcome. It was written by the Rosemead School of Psychology, an APA-accredited University which aims “to train clinical psychologists from a Christian perspective”. The book lays out four potential ways in which someone can view psychology and theology:

Personality Disorders 101: Obsessive-Compulsive PD

Standard

The final personality disorder in the current diagnostic system is Obsessive-Compulsive Personality Disorder (OCPD). First, I’ll explain why OCPD is not the same as Obsessive-Compulsive Disorder (OCD).

In OCD, someone’s obsessions and compulsions are entirely subjective, and individual to them. While the person knows their obsessions and fears are irrational, they feel forced to listen to those fears. At the core of OCD are ingrained if-then loops: if the person does not listen to those fears, something bad will happen to them or people they care about. If the person carries out their compulsions – either activities or rituals of specific thoughts – then they have briefly stopped those negative things from happening

As a stereotypical example, consider a person with OCD whose particular obsession and compulsion centres on locking doors. The person may need to spend an hour checking that every door in their house is locked before leaving, to prevent the overwhelming consequences of leaving one unlocked. However, they will not think differently of their family members for being able to leave after checking once. They may envy their family for being free from that worry and may feel guilty over how the time spent checking intrudes upon other family members.

In OCPD, the person’s rules and beliefs are not subjective and personal. They see their rules and methods as “objectively” correct, regardless of how complex, rigid or time consuming their approach may appear to others. Someone with OCPD who had specific rules about the correct location of every item in their house would require everyone else to abide by those rules exactly. If a housemate wanted to do things differently, the person with OCPD would see them as incorrect, illogical, or even morally wrong.

Personality Disorders 101: Dependent PD

Standard

Dependent Personality Disorder was introduced in the first version of the DSM in 1952. Originally, it was seen as a subtype of an now-unused condition named “Passive-Aggressive Personality Disorder”, but it was quickly changed to being a separate condition.

The core symptom of DPD is a person’s belief that they are unable to function independently. A person with DPD is compelled to rely excessively on either one person (often a significant other) or multiple people (such as a close group of friends) to help them navigate most or all parts of their life. This reliance is not out of laziness, nor a wish to delegate responsibility. Instead, it is to escape a primal fear of inability. A person with DPD sees the world as a cold, dangerous place, and usually believes that they are deficient and unable to survive on their own. Therefore, they will seek out others who they view as stronger and more capable to help them navigate through life. They are terrified of losing that support or angering their support network, as they believe they cannot function alone.

The DSM-5 describes DPD as a pervasive and excessive need to be taken care of, which leads to submissive and clinging behaviour and fears of separation. To be diagnosed with DPD, someone needs to have at least 5 of these criteria:

  • They have difficulty making everyday decisions without excessive advice and reassurance from others
  • They need others to assume responsibility for most major areas of his or her life
  • They struggle to disagree with others because they fear a loss of support or approval.
  • They have difficulty initiating projects or doing things on their own. because they lack self-confidence in their own judgment or abilities (Not because of lacking motivation/energy etc)
  • They go to extremes to get nurture and support from others, even to the point of volunteering for uncomfortable or dangerous situations
  • They feel uncomfortable or helpless when alone, as they are convinced they cannot care for themselves
  • They must urgently seek out new relationships to provide care and support when a relationship ends
  • They are unrealistically preoccupied with fears about being left to take care of themself alone

Personality Disorders 101: Avoidant PD

Standard

Today we move on to the Cluster C personality disorders, which are known as the “anxious” or “fearful” disorders. The first of these is Avoidant Personality Disorder (AvPD).

In 1911, Swiss psychiatrist Bleuler wrote about people who shied away from most social contact and activities. Bleuler is better-known for coining the words schizophrenia and schizoid, and he interpreted people’s avoidance through that lens; he assumed severe social avoidance was part of an unnoticed type of schizophrenia. However, this opinion was not widely accepted, and within ten years others described severe social avoidance as a separate condition.

AvPD is leagues beyond being shy and introverted. Instead, it is a deep-rooted and severe fear of rejection and criticism which impacts almost every aspect of a person’s life. While someone with AvPD will want to connect with and develop friendships with others, their fear of being criticised and disapproved of can be so painful that they are unable to take part in social activities. Their self-loathing and feelings of inferiority may be so strong that they assume others would not want to interact with them. As a result, they often interpret neutral statements as containing hidden rejections or reminders of their perceived social inability, which reinforces their perception of being socially inadequate.

The DSM-5 describes AvPD as a widespread pattern of being inhibited around people, feeling inadequate, and being very sensitive to any negative judgements. To be diagnosed with AvPD, someone must meet 4 of these criteria:

  • They avoid occupational activities that involve significant interpersonal contact because they fear criticism, disapproval, or rejection.
  • They are unwilling to get involved with people unless they can be certain of being liked.
  • They show restraint within close relationships because of the fear of being shamed or ridiculed
  • They are preoccupied with being criticized or rejected in social situations.
  • They are inhibited in new social situations because they feel inadequate
  • They seem themselves as socially inept, personally unappealing, or inferior to others
  • They are unusually reluctant to take personal risks or to engage in new activities in case they embarass themseleves.

Personality Disorders 101: Borderline PD/ Emotionally Unstable PD

Standard

Today’s topic, Borderline Personality Disorder, is perhaps the third most argued-about psychiatric disorder (with first and second place going to Dissociative Identity Disorder and ADHD/ADD).

One of the many contentious points is its name. When the DSM was first developed during the 1950s, psychiatrists divided mental health issues into “neurotic” and “psychotic”. People with “neurotic” illnesses were in distress but still aware of reality and that they were ill, while people with “psychotic” illnesses were detached from reality and often unaware that they were ill. Borderline personality disorder received its name because psychiatrists saw the symptoms as being on the border of both categories. However, that method of categorising mental health conditions is no longer used, so “borderline” now doesn’t mean anything. It can also be actively unhelpful, because people can assume it means that someone is on the border of having a mental health condition and not having one. The ICD-10 instead uses the name “Emotionally Unstable Personality Disorder”, which better reflects the condition’s core symptom.

A person with EUPD experiences much more intense and changeable emotions than a typical person, and the overwhelming nature of those emotions underpins the other EUPD symptoms. To be diagnosed with EUPD in the DSM-5, someone must meet 5 of the 9 criteria:
