0 YOU ever get the "Blue Monday

When the first workday of the week
drags around do you find the mental
gears stiff, and “General Ability” hit-
ting on only three cylinders?
Yes? Well, don’t let it worry you!
For. psychology, that omniscient and
comforting science,,says most of us are
naturally that way. 70!: Monday—if

nrday and Sunday are still worse; so
far as performance goes.- Briefly; the
:ests-on the 112 'showed a-gradual' in-'
crease in performance during th’e‘first
’sur days of the Week, with a marked
decline on Thursday which was not
altered to any great extent until Tues—
day. WTbursday Friday, fiatur’day and
Sunday were, in fact, the actual low
days for the undergraduates studied as '
agroup.
Dr. .W. Fernberger, assistant pro-
fessors in the psychology department,
University of Pennsylvania, and an ad-
visory editor of the Journal of. Experi-n
mental Psychology, which announced the
results of the tests, believes the findings
may be applied to individual perform-
ance in industry and business, as well
as to the work of students.
IN HIS olfice at College Hall, Dr. Fern-
berger explained. the importance of
the charts b1, nhich the daily records
have been plesented.
“They represent,” he said, .“a fur-
ther deVe! opmeut in the Study of in-
dividual productiw c ability. Earlier
workers haw published the results of 7
reseaiclx into camparative mental and
physical ability according to the hours "
of the day. but heretofore there has been
‘ little authoritatixe research into difior- 7

was to determine at what hour of the
day and on what day of. the week the

resent an average attained by 112 nor,
the] students nuclei careful observation.”
The tests was made and the report
piepared by Dr. Donald ,A Laird,‘:o
the. Colgate Psychological Laboratory-f.
He divided the students into squads of
sixteen and conducted the experiment
for six weeks. To avoid any self-con-
sciousness which might affect the result,
the subjects Were led to béli

In discussing this phase of his experi-

“Examination of the performance

“The peak for the Mormons in the

terms of addition it means that on Tum
day the average performance of the
112 subjects studied would have enabled
them to do 369 more additions per hour
than on Sunday, assuming that the rate
of the first few minutes is continued
without change for the longer-period.
“The peak of the substitution test, the
retention tests and the test of reading

In discussing his summary of per- 1:

At 8 o’clock; P. 151., it touches 92

reached at 94 per cent, as compared with
the 8 A. M. performance. At 10 o'clock
it sags again to 91 per cent and con-
tinues its steady droop until bedtime.

columns and double ‘columns 7is‘ at its -
peak at 11’. M. Single column addi-
tion, however, is lowest at 10 P. M.,
and double column at 4 P. M
“There is,” Dr. Laird points out, "a
steady decline in general performance,
until 4' P. M. This decline amounts to
about 10 per cent less than the perform-
ance at 8 A. M., which .is fivgvtimes the
standard deviation of the difference that
is being used. Following the evening
meal, there is a slight increase in the
performance, Which is lost again, how-
ever, inthc period from 10 until 11 P. M.
“These conclusions apply, not neces»
sarily to every individual student, but
represent accurately the average per-
formance of a large group, or the ‘typi-
cal student.‘ 11: may be perhaps that
there are individual exceptions'to these
findings as the result of habits of study -
and work. " It is doubtful if there are
variatitms. as a *result of one student
