Science Fact of the Day: Pregnancy and Strength Training

January 9, 2019

When I was a personal trainer I had always hypothesized that strength training would lead to positive outcomes for pregnant women and the child, particularly if they had been training prior to the conception of their child.

Since I'm not a research center and such training could be high risk, I just wouldn't train a pregnant woman. The wisdom in the early 2000s was, "don't engage in strength training if you're pregnant." Among trainers the wisdom was, "that doesn't make any sense, but don't do it to avoid a lawsuit."

Science Fact of the Day #2: Teacher Somatotype

October 8, 2017

As in all cases “science fact” is used loosely.

The Main Claim About Teacher Somatotypes

In Nonverbal Behavior in Interpersonal Relations the authors observed that:
"Teachers who are ectomorphic are usually perceived by students as anxious and less composed but perhaps intelligent. The endomorphic teacher is generally perceived by students as slow, lazy, under-prepared, and not dynamic in the classroom. The mesomorphic teacher is perceived as credible, depedable, likable, and competent but possibly tough and dominant." Virginia P Richmond and James C McCroskey, Nonverbal Behavior in Interpersonal Relations (Boston: Pearson/A and B, 2004), 269
For those who don't know:
  1. Ectomorphs are lanky body types
  2. Endomorphs are dad-bod types
  3. Mesomorphs are beefy (muscly) types
teppelin: “ Three common male body types: Endomorph (often “chubbier” men) • Soft and round body • Gains muscle and fat very easily • Is generally short and “stocky” • Round physique • Finds it hard to lose fat • Slow metabolism Mesomorph (the...

Is that a reasonable claim? What is the evidence?

Now, here's where things might get interesting. In this social-psychology text, several paragraphs per page will be riddled with citations. But this particular paragraph cites no studies. Is this just a personal observation? Is it an impression?

I don’t know.

Science Fact of the Day: Good Charlotte was on to something

October 19, 2016

I haven’t done a science fact of the day lately. Work is time consuming. Don’t forget, science facts of the day are my thoughts on and descriptions of what scientists say. In other words, it’s a fact that some scientists have said it. What I write is not necessarily a fact of nature nor something I even take to be the case.

In an article at Big Think, an author describes this analysis of online dating data.

Placebo and Intelligence

August 26, 2016

In a recent experiment, psychologists “designed a procedure to intentionally induce a placebo effect” in order to test the claims of intelligence increasing software.[1]

The study has a small sample size, but bear with me. 

In the control group (people who simply thought they were participating in an experiment) there was no difference in pre and post training intelligence. In the experimental group (who were told they were training to increase their intelligence) an increase in intelligence was measured (5-10 IQ points) after only one hour of training.

Science Fact of the Day #4: Francis de Sales and the Science of Performance

July 14, 2016

In a 2004 study, it results were discovered which “suggest that self-compassion is associated with adaptive motivational patterns and coping strategies in academic contexts…”

Self-compassion “involves being open to and aware of one’s own suffering, offering kindness and understanding towards oneself, desiring the self’s well-being, taking a nonjudgmental attitude towards one’s inadequacies and failures, and framing one’s own experience in light of the common human experience… "

Now, this is a fairly early study of self-compassion as a psychological model, but more recent research seems to confirm the results or at least fails to disprove them.

Science Fact of the Day #3: The Bargaining Model of Depression

July 8, 2016

Today we'll look at a fairly recent model of depression: the bargaining model.

In a 2003 book edited by Peter Hammerstein, Genetic and Cultural Evolution of Cooperation, chapter 6 is an essay (I believe based on a talk) on this model, “The Bargaining Model of Depression.”

The author, Edward Hagen, proposes depression might be explained as a strategy to gain assistance and support from powerful members of a social group by members which are weaker. This is due to the difficulty that physically or socially weaker people have utilizing force, threats of force, or persuasive rhetoric to achieve their goal (96-97).

Science Fact of the Day #1: Creatine Improves Brain Function

July 5, 2016

Something I try to do as a teacher is introduce students to new information from various fields of study in order to try to spark an interest in them that could propell them into a career in the future. So I find myself reading a lot of science articles about all sorts of random things. Many of them I do not share with the students but I think I'll start sharing them here to practice.
