take the effect and make it the cause

A study reported in the December 2007 Journal of Psychosomatic Research examined cognitive complaints in head-injured patients referred to the emergency department of a level 1 trauma center in the Netherlands.  A sample of 79 patients (ranging in age from 18 to 60) who had been admitted for mild traumatic brain injury were followed up over six months post-admission. In addition to a battery of neuropsychological tests and use of the Rivermead Postconcussional Symptoms Questionnaire (RPSQ), patients were also asked to self-monitor their cognitive and memory problems over a 12-day period. Results indicated that 39 per cent of the sample self-reported cognitive problems. These complaints were strongly related to lower educational levels, emotional distress, personality, and poorer physical functioning (especially fatigue) but not to actual extent of injury.  Severity of self-reported cognitive complaints was found not to be associated with the patients’ daily observations of cognitive problems or with outcome on a range of neuropsychological tests.  The researchers concluded that self-reported cognitive complaints were more strongly related to preexisting personality factors, as well as physical and emotional problems rather than actual cognitive impairments. This would suggest that treatment of emotional distress and fatigue may also reduce cognitive complaints. They also concluded that neuropsychological screening and daily monitoring of complaints is a useful method to gather information about the frequency and pattern of cognitive problems in regular life.

Mysteries Of The Mind Explored In V.S. Ramachandran Video!

Tuesday, April 1st, 2008


           Thanks to Gaetan Lee for permission to use this Photo.

Renowned as one of the most gifted, original, and charismatic thinkers in the world; V.S. Ramachandran is a neurologist with an almost preternatural understanding of the brain’s deepest mechanisms and the nature of consciousness.

Ramachandran’s insights into such facinating enigmas as phantom limb syndrome, synesthesia, and capgras delusion continue to both inspire and puzzle the psycho-scientific community, while his entertaining presentations always promise to dazzle even the most cynical of audiences. Check out the following video from the TED conference. Lose your mind.

New Study Questions The Effectiveness Of Anti-Depressants: Why Is This News?

Wednesday, February 27th, 2008

Are we on this again?

Study doubts the effectiveness of antidepressant drugs.”  Or, even better, as per The Independent: “Antidepressant drugs don’t work– official study.

I don’t know what passes for official nowadays.  The data is the exact same data that has existed for 30 years.  Yes, these authors are acting like they FOIA-ed the second Zapruder film, but let me assure you it’s the same old data.  These authors did the exact same study in 2002.  So have twenty other groups.  This is not new. 

But it is news.  The question is why.

I have a side question.  Why is it that when an article says something works, people are suspicious of bias, but when an article says something doesn’t work, everyone thinks it’s objective science?   IT’S ALL BIAS.  

People are completely missing the point of this paper and all the other recent re-investigations, the true social and clinical consequences of them.  For example: they’re saying antidepressants are no good.  Ok.  What do you think doctors are going to use  instead?  Psychoanalysis?  Nothing?  They’re going to prescribe antipsychotics.  Are you listening to me?  I’m not even saying this is clinically wrong to do, but do you not see the setup?  Abre los ojos, man.

“We” Are Connective Intelligence

The NMC/EDUCAUSE 2008 Horizon Report (.pdf) is a great resource. Educators and administrators will do well to consider its contents in their planning. I have a small concern. Something about the notion of collective intelligence doesn’t sit well with me. I can’t quite put my finger on it. I can (and have) used the term myself to explain the combined efforts of “the many” in achieving an outcome, solving a problem, or determining the value of a resources (such as voting/rating systems in Amazon and Digg). As a term, it resonates with people - the value of being part of a larger community and sharing and creating information together is valuable, if not necessary today.  I’m not comfortable with collective intelligence - I prefer the notion of connective intelligence.

Derrick de Kerckhove explored this concept in 1997, well before we had the distributed collaboration tools we’re using today. James Surowiecki explored a similar concept in Wisdom of the Crowds. Surowiecki’s book is often misunderstood. He makes the point that people do not think together in coming to certain conclusions, but rather than people think on their own and the value of the collaborative comes in the connection and combination of ideas. Each person retains their own identity and ideas, but they are shaped and influenced by the work of others. (more…)

Ashworth Contributing Blogger Seth Woolf Is Contacted By Dr. Phil Show!

Wednesday, February 13th, 2008

Recently I was contacted by an associate producer from the Dr. Phil show. Are they seeing if I’d be a good guest? It certainly appears like that’s a possibility. So, in addition to getting some very desperately needed help from Dr. Phil and his team, I may one day soon be able to give my bastion of loyal readers a quasi-insider’s view of the show and its’ process. All I can say is, pray for me, and, for now, enjoy this correspondence, edited, of course, for privacy reasons: (more…)

Take This Test To Find True Love!

2 and 2 baby!
                 Thanks to Robras for permission to use this Photo.

You may have recently seen reports on TV recently about a new wave of online dating sites that match people based on genetic traits.  Although clinical, this method seems preferable to the reality show formula of trapping 100 degenerate men and women in a rented mansion until a final rose, clock, or beat down is won.  There must be a better way to figure out what type of relationship is best for you, right?  The following online test takes only five minutes to complete and promises to provide you with a relationship profile suiting your romantic preferences.  The test was developed by two prominent psychologists and turns out to be rather accurate.  I took it myself before posting this blog.  Let’s just say I have some work to do before my black heart turns gold.  If anyone wants to share their results, we would love to hear from you in the comments section.  This test is fun and insightful.  Take it!

Seeing Dr. Phil From Different Angles…

Monday, February 4th, 2008


                          Thanks to Karen Geiger for permission to use this Photo.

I really enjoyed Seth Woolf’s response to Deb’s solid commentary on his previous post. Since we don’t yet have our comments section clearly displayed on this blog, I’ve posted this conversation as an original post for everyone to see and engage. What are your thoughts?

From Deb: 

Dear Sir — I believe you have missed the point of what Dr. Phil has been trying to achieve. As young people, typically all of us do not realize the consequences of actions. I can indicate to you that as a owner of a company, these kind of posting would stop me from hiring an individual, no so much as their right to participate in such activity, but in that the judgment of said individual is not who I want representing my company. In short…it is that simple and professionally said individuals are limiting their options later in life, as they age and realize that childhood was not meant for public display. 

From Seth: 

It is perhaps true that I have “missed the point of what Dr. Phil has been trying to achieve” but, if so, it is because I find his aims pointless. I simply feel the cause and effect of this situation has been confused. If employers look down on such technological behavior and confessionalism, I think it says more about their own bourgeoise biases, and less about the quality of the candidates. More importantly, I would also like to counter your claim that “As young people, typically all of us do not realize the consequences of our actions.” This is a sweeping statement about young people, one which I do not follow. For one, I don’t see “young people” as a definable, homogeneous group. I’m 22, am I a young person? What about a twelve year old in Auswitz? What about an eighty year old with the mental capacities of a person one tenth his or her age? Is it for individuals to decide, society, or who? Similarly, I don’t see how a person, regardless of age, could realize all the consequences of his or her actions. Everyone, again regardless of age, must simply act with what information they have at a given moment. (more…)

New Psychological Study Concludes Culture Influences Brain Function…

It’s becoming apparent that the future of psychological research will not resemble the past.  The psychologists of today analyze brain images, perceptual stimuli, and magnetic scans.  Even at the height of Freud’s psychoanalytic late 19th and early 20th century, the discipline was widely considered a “quack science” at best.  Like other traditional sciences such as chemistry and physics, advances in technology have allowed researchers to see inside the subject, whether it be cells or black holes, like never before.  With the introduction of sophisticated neurological testing methods, the psychology field is rapidly taking on the characteristics of a “hard science.”  The following article focuses on a study conducted at M.I.T. in which researchers aimed to determine if cultural differences directly effect how the brain perceives stimuli, performs memory functions, and everything else you can think of.  The conclusions are fascinating.  This is a deep topic, so help me understand it by sharing your perspectives.  I recommend that you read this study.  Check it out by clicking here

The Disturbing Connection Between A Teen’s Social Standing And Weight Gain…

Wednesday, January 16th, 2008


              Thanks to Todd Ehlers for permission to use this Photo.

It is likely that many diverse factors have contributed to the current obesity epidemic. Fast food, less activity, trans fats, viruses, big portions, and so on have all been blamed for our increasing waistlines. The more we understand the phenomenon, the better equipped we are to deal with it.

Adina Lemeshow and her colleagues have added a new consideration–social status [1]. Teen girls were asked to rate themselves on a ten point social standing scale, with 10 representing people with the most respect and highest standing and a 1 representing people “no one wants to hang around with.” Girls who rated themselves less than 5 were 69 percent more likely to experience a two unit or more increase in BMI over the following two years, even after other factors such as socioeconomic status, TV viewing habits, mother’s BMI, and depression were controlled.

Are Subliminal Messages Controlling You?

Monday, January 7th, 2008

 
            Thanks to Kena Takahashi for permission to use this Photo.

Most of us are a bit uneasy about the idea that somebody can influence our thinking without our awareness. We are bombarded by enough obvious persuasive messages as it is, without having to worry about messages we don’t even notice.

Although this example is not exactly subtle, and one wonders if it in fact has any effect on behavior, the PETA brick, purchased at the San Diego Padres’ PETCO stadium, spells out “Boycott Petco” if you just look at the first letter of each word.  

The study of subliminal messages (messages that are “sub” or below our “limin” or threshold of awareness) has a long history. Back in 1956, social psychologist James Vicary claimed that he could boost sales of movie popcorn and Coca Cola by flashing the messages “eat popcorn” or “drink Coca Cola” during a movie. In spite of Vicary’s later confession that he made up his data, not to mention the failure of scientists to replicate his results, many people still believe that subliminal messages work. Americans spend more than 50 million dollars a year on subliminal tapes for self-improvement, and much controversy has surrounded subliminal or back-masked messages in music.

More recently, Vokey has distinguished between a person’s objective and subjective thresholds for awareness [1]. A person responding to a stimulus at the objective threshold will do no better than chance in identifying its presence, and these stimuli appear to have no impact on behavior. However, a stimulus falling between a person’s objective and subjective thresholds will be detected at better than chance levels, and does appear to have the ability to influence behavior. (more…)
