Check out Science, 12 Feb 2010, page 776. Studies of cockroaches
fleeing from a disturbance and running up a wall when they get to it. It
seems that 77% of them run as fast as they can and crash head-on into the
wall, then transition to going up the wall so fast that to the human eye
(but not the slow-motion camera) it all looks continuous. Doesn’t seem to
hurt them.
Best,

I’ve was very successful killing cockroaches in SC for 40 year. I never let them get to a wall by holding on object over them that blocked out the light (creates a shadow) and they stop. I just mash (a common word use in the South) them when they stop. It’s quite simple.

I was afraid to open this; I thought it was from a tenant;-)

Ah, I really love cockroach studies. I read one in graduate school that
neared that golden area of near perfect absurdity. Without going into
detail, the psychologist, Robert Zajonc, attempted to replicate a classic
study done by his teacher. Unfortunately, Dr. Zajonc could not replicate
the study. His reasoning for the failure was that he had used a different
species of cockroach. However, this simple account did not deter him from
generalizing to humans who can be found across a wide expanse of the animal
kingdom.
Cheers to all the psychologists who study cockroaches (or chickens or ants)
in an attempt to understand human behavior. Well, it does keep them
occupied and off the streets where they could hurt themselves. So it goes.

Hello, Dan, long time no see.
DM: Ah, I really love cockroach studies.
BP: Me too, and rats, too. But I did enjoy the image of those cockroaches bashing their brains out and going on as if nothing had happened.

Bill and Others,
I've been lurking and couldn't resist talking about cockroaches. I talk
about some of the studies with my students. Most of the students (and
cockroaches) live in substandard housing that encircles the campus. The
students know all about how cockroaches act. Some of their stories are a
hoot. I'll have to include the wall-crashing observations. They'll love
it.
I'll try to get on more. I've had a few health problems along with
grandchildren and too much work that gets in the way of my intellectual
interests.
Always,
Dan
