'U' EXPERIMENTS ON RODENTS:
Tests Show Gamblers, Rats Similar
By FRAN SHELDON
s . * *
, Although there is little basis for
the belief that gamblers are all
rats, psychological tests being car-
ried on in a University laboratory
indicate fundamentally the two
may have a lot in common.
Prof. Edward L. Walker of the
psychology department, in a study
of alternation phenomena in the
four-footed rodents has been able
to draw an analogy between the
action of rats when placed in a
planned situation and the action
of gamblers in a "tight spot."

BY PLACING the animals in
the foot of a T-shaped run, and
providing some stimulus to start
them running, Walker has demon-
strated the animals, for no ap-
parent reason, will tend to run on
a second trial in the opposite direc-
tion from the one they took on the
This. tendency, he explained,
is due to the inevitable effect the
first trial has on the "attitude"
of the animal toward the second.
If it had no effect on the animal
at all there would be equal chance
he would run in either direction.
This has been disproved in prac-
tice, and it has been further dem-
onstrated the action of most rats
falls into the same set pattern, he
TAKEN OUT of its setting, Wal-
ker showed how this tendency to
alternate is analogous to the little
publicized gamblers' fallacy, upon
which all the better gambling es-
tablishments depend for their pro-
This fallacy, he explained,
causes gamblers to be misled by
sequence. For example, a gamb-
ler betting on the fall of a coin
knows on the first throw there

Human Biology Institute
Studies Heredity in Mice
By PHYLLIS WILLAR
A large-eared, hearty, brown
genus of mice has been the subject
of many years of research which
is now being carried on at the In-
stitute of Human Biology, situated
in the back of a courtyard on East
The genus, Peromyscus, has
figured largely in the experiments
on the heredity of racial charac-
teristics which Prof. Lee R. Dice.
director of the Institute, has been
carrying on since 1925. He began
his studies in the Laboratory of
Mammalian Genetics which ex-
panded into what has been the
Institute of Human Biology for
THE INSTITUTE now includes
the Heredity Clinic, the Biogeog-
raphy Section, the Community
Dynamics Section, and the Lab-
oratory of Vertebrate Biology in
which Prof. Dice is studying his
native American mice.
All the research is combined
into as effort to discover fun-
damental principles of biology
which can be related back to hu-
The study of the reactions which
Peromyscus has to certain experi-
ments can lead Prof. Dice and his
associates to predict what other
animals will do in similar situa-
tions. This can then lead to pre-
dictions on human habits.
IN THE HEREDITY Clinic, re-
search is trying to establish what
diseases are hereditary, the effects
of atomic radiation in producing
mutations in man, and the pos-

The Biogeography section is di-
recting its, investigations primar-

information through these two
groups about the movement and

extinct. Located in the Museums

direction of Prof. L. C. Stuart of
the zoology department.

In addition to the different de-

including an assortative mating

Union To Open
Small campus organizations
may, beginning today, take ad-
vantage of the Union's typing,
mimeographing and postcard mim-
eographing facilities under the
Union's new secretariat service.
Arranging a time and procur-
ring stencils for mimeographing
may be done by contacting the of-
fice manager in the student of-
fices.between 3 and 5 p.m. any day
during the week.
The student offices will be open
from 7 to 8 p.m. Tuesdays, Wed-
nesdays and Thursdays. The pro-
ject will be run at cost and will
be handled through the disperse-
ment authorization sheet system
of the office of Student Affairs.
Jobs Talk Set
Summer projects in Interna-
tional student relations will be
discussed by Barbara Grant, col-
lege secretary for the American
Friends service committee during a
three day stay in Ann Arbor.
Miss Grant will arrive in Ann
Arbor today and will meet with
students at 5 p.m. atthe Congre-
gational Guild House. She will re-
main in Ann Arbor until Friday.
International seminars, student
work camps across the United
States, and trips to Europe and
Japan are planned for this sum-
mer. Students wishing to make ar-
rangements through the Friends
can make appointments to see Miss
Grant by calling Lane Hall.

Willard told the group "broad"
education, such as we have in this
country and Canada will prevent
countries from "stagnating," and
indicated that in some European
countries, social and economic
forces were opposed to "broad"

However, Walker continued, if
the coin falls heads up several
times in a row the tendency of
the gambler is to become more cer-

on this alternative despite the factf
that each individual throw still has
equal chance to fall either way.

ACTUALLY, although the prob-
ability of a coin falling the same
way ten times in a row is one in
a thousand, the possibility of the
eleventh try falling the same way
is still 50-50, he pointed out.

explained, are affected by the out-

reasoning is influenced and they
have a distorted picture of the
