Caring for your introvert

with one comment

Now that I’ve been presented with obvious evidence that I’m an introvert, I found this article by Jonathan Rauch quite interesting:

Do you know someone who needs hours alone every day? Who loves quiet conversations about feelings or ideas, and can give a dynamite presentation to a big audience, but seems awkward in groups and maladroit at small talk? Who has to be dragged to parties and then needs the rest of the day to recuperate? Who growls or scowls or grunts or winces when accosted with pleasantries by people who are just trying to be nice?

If so, do you tell this person he is "too serious," or ask if he is okay? Regard him as aloof, arrogant, rude? Redouble your efforts to draw him out?

If you answered yes to these questions, chances are that you have an introvert on your hands—and that you aren’t caring for him properly. Science has learned a good deal in recent years about the habits and requirements of introverts. It has even learned, by means of brain scans, that introverts process information differently from other people (I am not making this up). If you are behind the curve on this important matter, be reassured that you are not alone. Introverts may be common, but they are also among the most misunderstood and aggrieved groups in America, possibly the world.

I know. My name is Jonathan, and I am an introvert.

Oh, for years I denied it. After all, I have good social skills. I am not morose or misanthropic. Usually. I am far from shy. I love long conversations that explore intimate thoughts or passionate interests. But at last I have self-identified and come out to my friends and colleagues. In doing so, I have found myself liberated from any number of damaging misconceptions and stereotypes. Now I am here to tell you what you need to know in order to respond sensitively and supportively to your own introverted family members, friends, and colleagues. Remember, someone you know, respect, and interact with every day is an introvert, and you are probably driving this person nuts. It pays to learn the warning signs.

What is introversion? In its modern sense, the concept goes back to the 1920s and the psychologist Carl Jung…

We are HIGHLY spatially oriented creatures

leave a comment »

As you might expect from our arboreal ancestry. Mind Hacks:

There’s an intriguing study about to be published in Psychological Science finding that people wearing prism glasses that shift everything to the right overestimate the passage of time, while people wearing left-shift glasses underestimate it.

The researchers, led by psychologist Francesca Frassinetti, asked participants to watch a square appear on-screen for varying time periods, and then reproduce the duration or half the duration with a key press.

Glasses that skewed vision to the left seemed to shrink time, while glasses that skew everything to the right expanded it.

Apart from the interesting perceptual effect, it gives further evidence for the idea that our internals model of space and time are heavily linked, to the point where modifying one has a knock-on effect on the other.

In fact, there is increasing evidence that other abstract concepts are implicitly understood as having a spatial layout. Experiments on the SNARC effect have found that numbers seem to have a ‘location’, with larger numbers being on the right and smaller numbers on the left.

At least, that seems to be the case for native English-speakers, but for Arabic speakers, where text is written right-to-left, the reverse seems to be true.

It would be interesting to whether Arabic speakers show a reverse time alteration effect of if they wear prism glasses. Whatever the answer, it would raise lots of interesting questions about how much language influences our abstract ideas and whether it only applies to certain concepts.

Prism glasses have long been a tool in psychology and there is a mountain of research on how we adjust to living in the world even when everything is shifted through the lens.

Tom recently found a fantastic (1950s?) archive film called ‘Living in a Reversed World: Some Experiments on How We See the Directions of Things’ where several volunteers are asked to wear prism glasses for weeks on end.

Hilarity ensues, at least at first, but as co-ordination skills adapt the volunteers can go about their daily tasks, to the point of being able to ride bicycles, even when their vision has been flipped around.

Stalkers and assassins

leave a comment »

Interesting post from Mind Hacks:

I’ve just found this fascinating 2006 article by a consultant psychiatrist to the US Secret Service that classifies the types of stalkers and assassins that have troubled the President of the United States.

The piece, by psychiatry professor Robert Phillips, reviews past classifications of presidential harassers and cases from the literature to produce a list of main types.

In my work as consultant to the U.S. Secret Service on protective intelligence cases, it is my clinical assessment that aids in their ultimate determination of who poses a potential risk to a protectee.

In performing evaluations of persons who have either threatened or attacked presidents, pursued them without nefarious intent, or appeared at the White House without invitation, I have searched for a framework that would allow me to integrate my diagnostic opinion of an individual subject with a conceptualization of what is known about others who have acted similarly.

Phillips’ classification includes:

* The Resentful Presidential Stalker or Assassin
* The Pathologically Obsessed Presidential Stalker or Assassin
* The Presidential Infamy Seeker
* The Presidential Nuisance or Presidential Attention Seeker

But perhaps most interesting is the part where he illustrates each type with examples from past cases.

These include famous cases, such as John Hinckley – the man who shot President Reagan but was apparently also a stalker of Carter, to less well known cases such as one woman referred to only as ‘Ms Doe’ who "possessed a delusional love interest" in Clinton.

It’s interesting to compare this classification with the independently created typology of stalkers of the British royal family drawn from the Metropolitan Police’s Royalty Protection Unit files.

Tools = temporary body parts

leave a comment »

Interesting post at Mind Hacks:

Not Exactly Rocket Science covers an intriguing study that provides further evidence for the theory that the brain treats tools as temporary body parts.

Using tools has lots of interesting effects on our perception. In one of my favourite studies, psychologist Dennis Proffitt found that we perceive distances as shorter when we have a tool in our hand, but only when we intend to use it.

This latest study found that using a tool for only a few minutes modified the body’s action settings. In the experiment, participants were asked to repeatedly pick up a block that had been placed in the middle of the table.

Then, they had to repeat the same actions with a grabber – a long, mechanical lever tipped with a two-fingered "hand" – and then a third time, with their own hand again.

Small LEDs on the volunteers’ hands allowed Cardinali to track their movements and calculate the speed and acceleration of their arms. She found that they reached for the block differently after they had been accustomed to the grabber, taking longer to accelerate their hands more slowly and to seize the block (although once they actually touched the blocks, they grasped them in just the same way as before). The delays even affected the speed at which they pointed at the block, a behaviour that wasn’t "trained" by the grabber.

To Cardinali, these results suggested that after using the grabber, the volunteers’ had included it into their mental representation of their own arms. Because of that, they felt that their arms were longer than they actually were and reached for the block more slowly.

The psychology of the scam

with one comment

Mind Hacks posts:

I’m just reading a fascinating report on the psychology of why people fall for scams, commissioned by the UK government’s Office of Fair Trading and created by Exeter University’s psychology department.

It’s a 260 page monster, so is not exactly bed time reading, but was drawn from in-depth interviews from scam victims, examination of scam material, two questionnaire studies and a behavioural experiment.

Here’s some of the punchlines grabbed from the executive summary. The report concluded that the most successful scams involve:

Appeals to trust and authority: people tend to obey authorities so scammers use, and victims fall for, cues that make the offer look like a legitimate one being made by a reliable official institution or established reputable business.

Visceral triggers: scams exploit basic human desires and needs – such as greed, fear, avoidance of physical pain, or the desire to be liked – in order to provoke intuitive reactions and reduce the motivation of people to process the content of the scam message deeply.

Scarcity cues. Scams are often personalised to create the impression that the offer is unique to the recipient.

Induction of behavioural commitment. Scammers ask their potential victims to make small steps of compliance to draw them in, and thereby cause victims to feel committed to continue sending money.

The disproportionate relation between the size of the alleged reward and the cost of trying to obtain it. Scam victims are led to focus on the alleged big prize or reward in comparison to the relatively small amount of money they have to send in order to obtain their windfall.

Lack of emotional control. Compared to non-victims, scam victims report being less able to regulate and resist emotions associated with scam offers. They seem to be unduly open to persuasion, or perhaps unduly undiscriminating about who they allow to persuade them.

And here’s a couple of counter-intuitive kickers:

Scam victims often have better than average background knowledge in the area of the scam content. For example, it seems that people with experience of playing legitimate prize draws and lotteries are more likely to fall for a scam in this area than people with less knowledge and experience in this field. This also applies to those with some knowledge of investments. Such knowledge can increase rather than decrease the risk of becoming a victim.

Scam victims report that they put more cognitive effort into analysing scam content than non-victims. This contradicts the intuitive suggestion that people fall victim to scams because they invest too little cognitive energy in investigating their content, and thus overlook potential information that might betray the scam.

Interesting, people who fall for scams often have a feeling that it’s dodgy. The report suggests we trust our get instincts. If it seems to good to be true, it probably is.

We like to think that only other people fall for scams, but as I’m working my way through the report it’s becoming clear that those things that we think make us resistant to scams (a keen analytical mind) are not what help us avoid being a victim.

A really fascinating read and a great example of applied psychology.

Mindset as positive voodoo

leave a comment »

Yesterday I blogged about nocebos: when you mind holds beliefs that lead it to attack the body. Last night I was reading Mindset, by Carol Dweck, PhD, and it struck me that she is in a way exploring the same sort of phenomenon, though on the positive side and in different language. The two approaches are looking at the same general thing, but from different angles and with different vocabularies.

Here’s the opening of her book:

When I was a young researcher, just starting out, something happened that changed my life. I was obsessed with understanding how people cope with failures, and I decided to study it by watching how students grapple with hard problems. So I brought children one at a time to a room in their school, made them comfortable, and then gave them a series of puzzles to solve. The first ones were fairly easy, but the next ones were hard. As the students grunted, perspired, and toiled, I watched their strategies and probed what they were thinking and feeling. I expected differences among children in how they coped with the difficulty, but I saw something I never expected.

Confronted with the hard puzzles, one ten-year-old boy pulled up his chair, rubbed his hands together, smacked his lips, and cried out, I love a challenge!" Another, sweating away on these puzzles, looked up with a pleased expression and said with authority, "You know, I was hoping this would be informative."

What’s wrong with them? I wondered. I always thought you coped with failure or you didn’t cope with failure. I never thought anyone loved failure. Were these alien children or were they on to something?

Everyone has a role model, someone who pointed the way at a critical moment in their lives. These children were my role models. They obviously knew something I didn’t and I was determined to figure it out—to understand the kind of mindset that could turn a failure into a gift.

What did they know? They knew that human qualities, such as intellectual skills, could be cultivated through effort. And that’s what they were doing—getting smarter. Not only weren’t they discouraged by failure, they didn’t even think they were failing. They thought they were learning.

I, on the other hand, though human qualities were carved in stone. You were smart or you weren’t, and failure meant you weren’t. It was that simple. If you could arrange successes and avoid failures (at all costs), you could stay smart. Struggles, mistakes, perseverance were just not part of this picture.

Whether human qualities are things that can be cultivated or things that are carved in stone is an old issue. What these beliefs mean for you is a new one: What are the consequences of thinking that your intelligence or personality is something you can develop, as opposed to something that is a fixed, deep-seated trait? Let’s first look in on the age-old, fiercely waged debate about human nature and then return to the question of what these beliefs mean for you…

It’s a fascinating book with many implications for child-rearing. For example, you never praise a child for how smart s/he is, but rather for how well they work. Good grades are attributed to good work, not to intelligence. You can find more information in this earlier post.

I have to admit that I was praised for being smart and really didn’t learn how to study and work at things until I was an adult—and study skills are best learned very young, otherwise it’s difficult to embed them deeply enough.
