Pkbs»INTRODUCTION
I
have
been invited to contribute a preface to thisbook,
though
when
I ask myself,why
any book from
Professor Thorndike's pen should need
an
introductionto the public by another hand, I find
no
answer.Both
as
an
experimental investigator, as a critic of otherin-vestigators,
and
asan expounder
of results, he stands inthe very forefront of
American
psychologists,and
hisreferences to
my
works
in the text that follows will, Iam
sure, introduceme
tomore
readers than I canintro-duce
him
toby
my
preface.In addition to the
monographs which have
been pour-ingfrom
thepress for twenty yearspast,we
have by
thistime, both in English
and
inGerman,
a very largenum-ber of general text-books,
some
largerand
some
smaller,but all coveringthe
ground
inways
which, so far asstu-dents go, are practical equivalents for each other.
The
main
subdivisions, principles,and
features of descriptivepsychology are at present well
made
out.and
writers areagreed about them. If one has read earlier books, one need not read the very newest one in order to catch
up
with the progress of the science.
The
differences inthem
are largely of orderand
emphasis, or of fondnesson
the authors' parts for certain phrases, or for theirown
modes
ofapproach toparticular questions. Itisone
and
thesame body
of facts withwhich
they allmake
usacquainted.
Some
of these treatises indeedgivemuch more
promi-nence to the details of experimentation than othersartificial experimentation, I
mean,
with physicalInstru-ments,
and
measurements.A
rapid glance at Professor Thorndike's table of contentsmight
leadone
to sethim
down
as not belonging to the experimental class ofpsy-chologists.
He
ignores the variousmethods
of provingFechner's psycho-physic law,
and
makes
no
reference tochronoscopes, or to acoustical or optical technics.
Yet
in anotherand
psychologically in amore
vital sense hisbook
is a laboratorymanual
of themost
energeticand
continuous kind.
When
I first looked at the proofsand
saw
each sec-tion followedby
a set of neatlynumbered
exercises,problems,
and
questions in fine print, I confess that Ishuddered for a
moment.
Can
it be, I thought, that the author's long connection with the Teachers College ismaking
even ofhim
a high-priest of theAmerican
"text-book"
Moloch, inwhose
belly living children'sminds
areturned to ashes,
and
whose
ritual lies in text-books inwhich
the science is pre-digested for the teacherby
everyexpository artifice
and
for the pupilcomminuted
intosmall print
and
large print,and
paragraph-headings,and
cross-references
and
examination questions,and
everyother up-to-date device for frustrating the natural
move-ment
of themind
when
reading,and
preventing thatirre-sponsible rumination of the material in one's
own
way
which is the soul of culture?
Can
it be, I said, thatThorndikc
himself is sacrificing tomachinery and
dis-continuity?
Rut
I had not readmany
of the galleys before I gotthe opposite impression.
There
are, it is true,discon-tinuities in the
book
which
might
slightly disconcert acritic with a l'>ench turn of taste, but that is because of
the intense concretencss with
which
the author feels his subjectand
wishes tomake
his reader feel it.The
prob-Introduction vii
lems
and
questions are uniquely to that end.They
arelaboratory
work
of themost
continuous description,and
the text is like unto
them
for concreteness. ProfessorThomdike
hasmore
horror of vagueness, of scholasticphrases, of scientific
humbug
thanany
psychologist withwhom
Iam
acquainted. I defyany
teacher or student togo
through thisbook
as it is written,and
not to carryaway
an
absolutely first-handacquaintance with thework-ings of the
human
mind,and
with the realities asdistin-guished
from
the pedantriesand
artificialities ofpsy-cholog>'.
The
author'ssuperabounding
fertility infamil-iar illustrations of
what
he is describingamounts
togenius. I
might
enter intoan
exposition ofsome
of the other peculiarities of his treatise, but this quality ofex-ceeding realism
seems
to cap the othersand
to give iteminence
among
the long list of psychology-bookswhich
readers
now-a-days have
to choose from.It is not a
work
for lazy readers,however; and
lazyreading also has a sacred place in the universe of
educa-tion.
But
Iseem
to foresee for it a powerfulanti-pedantic influence,
and
Iaugur
for it a ver>' greatsuc-cess indeed in class-rooms. So, with
no
more
pref-atory words, I heartilyrecommend
it to all thosewho
are interested in spreading theknowledge
of our science.William
James.
The
aim
of thisbook
is to help students to learn thegeneral principles of psychology.
Those
factswhich
can
most
profitably bemade
the subject matter of acourse in general psychology are presented with an
abundance
of concrete illustrations, experiments,exer-cises
and
questions,by which
the studentmay
secure realrather than verbal conceptions
and
may
test, applyand
make
permanent
his knowledge.A
good
method
of studying thebook
is probably (i)to reada section through quickly, then (2) to read itwith
care, jotting
down
in a notebook
every question thatseems
to beanswered by
the text.Next
(3) withoutthebook
try toanswer
those questions; hunting out theanswers
when
unable to givethem from
memory.
(4)Do
the printed exercises, writingdown
eachanswer
or,if it is too long, its
main
point. (5)Do
any
experimentsin connection with the section. (6)
When
the several sections of a chapter have all been thus studied, writedown
the general questionswhich
thewhole
chapter has answered,and
after an interval of several days try togive clear and reasonably adequate answers to these
questions in writing.
The
references for further reading noted at the end of each chaptermay
best be read only after the text itselfis mastered.
The
referencesmarked
A
are for students in general, thosemarked
R
are for students especiallydesirous of increasing their
knowledge

Professor WilliamJames
Iowe
thecommon
debt of all psychologistsdue
for the geniuswhich
hasbeen
our
inspirationand
the scholarshipwhich
has been ourguide.
The
obligation is patent in every chapter. In-deed, the best service I wish for thisbook
is that itmay
introduce its readers to that masterpiece of thought
and
expression, the Principles of Psychology. I
owe
alsoa personal debt for unfailing kindness
and
This
book
is designed to serve as atext-book forstu-dents
who
have
had no
previous training in psychology,who
will not in nine cases out of ten takeany
consider-able
amount
ofadvanced
work
in psychology,and
who
need
psychologicalknowledge and
insight to fitthem
to study, not the special theories of philosophy, but thegen-eral facts of
human
nature.For
such students trainingin
methods and
technique alone is almost futile: they arenot to be expert psychologists, but intelligent
men
and
women.
Training in the analysis of the process ofthought is equally inadequate: they need
more
thanan
introductiontologic
and
philosophy.A
coursewhich
re-duces psychology to a
mass
of technicalwords and
defi-nitions is criminal: ithides realities
from
the studentand
either encourages
him
in verbal quibbling or destroys allinterest in the study of mental facts. It is the right
and
the duty of the psychologist as a thinker to specialize,
to be an experimentalist, or analyst, or comparative
psy-chologist.
But
it is the right of the student in a generalcourse
on
psychology todemand
a fair representation of the science as a whole. Thisbook
is therefore eclectic insubject matter
and
in method. Description, definition,analysis, experimentation, comparative
and
geneticstudies
—
no
one of these can wisely be omitted.This
book
representsno
particular kind ofpsychologypeculiar to the author, nor
any
radical departuresfrom
the general usage of
modern
text-books on psychology.Some
of its features do, however, varyfrom
those of thePreface for Teachers xi
The
description of the brainand
sense organsfollows the recent views instead of those current in the early eighties.
By
thus discarding the unprofitablegeography
of 'convolutions,' 'centers'and
'tracts'and
utilizing the real facts of the constitution of the nervous
system,
we
not only give the studentknowledge
of atruly explanatory sort
which he
can apply topsychologi-cal facts, but also supplant an incoherent
mass
of detailby
a simpleand
clear hypothesis.The
length in pagesof Part II is
due
to the photographsand drawings and
represents a shortening rather than a lengthening of the student's time
and
effort.The
descriptive or structural psychology has beensharply separated
from
thedynamic
psychology-.For
instance, instead of taking
up
inone
chapter both thenature of percepts
and
the laws of mental actionin-volved in perception
and
illusion, Ihave
put the latter inPart III along with such topics as instinct, habit
and
the association of ideas.The
oldercustom
is a relic of the'faculty psychology'
and
inevitably disposes the studentto believe that perception,
memory,
reasoningand
thelike are subtle
dynamic
forces actingon
mentalproces-ses.
By
theseparation thereal value of the terms,sensa-tions, percepts, images, memories, judgments, emotions
and
the like,—
namely, their value as terms describing qualitative differences,—
is preserved. Needless to say,the
newer arrangement
is not only truer to the facts, butalso
more
teachable.Dynamic
psychology is given a place in thisbook
more
in accord with the place it holds in present psy-chologicalthought than iscustomary
in elementary books.It is surely wise to give adequate space to the facts
and
laws of instinct, capacity, habit, discrimination, analysis,
selective thinking, ideo-motor action
and
choice.They
are the least technical but at the
same
time the bestorganized
and most
instructive topics in psychology. In one particular the authorabandons
the accepteddoctrine of the psychology books.
That images
of the resident or remote sensations producedby
amovement
should be the usual excitant to the
movement,
he cannotbelieve
and
has never taught. In theview
presented inthe text he has the support of the opinions reached
by
Kirkpatrick,
Woodworth
and
Bair in the course of actual investigations of voluntary action.The
text statesfrankly that the majority of psychologists believe other-wise.
The
exercisesand
experiments are intended to serve the purpose, not of interesting puzzles or theses to be argued, but rather that served by the problems of thealgebra or physics book,
by
the sentence-writing of a text-book in Latin or French,and by
the experimentsand
demonstrations of a course in chemistry.They
are to give the studentsome
very definite thing to do,which
he
can do,and
which
can be definitely corrected orap-proved
by
the instructor. It is difficult to g^t such defi-nitematerial for studyand
practice in the mentalsciences other than logic, but it is a prime necessity for successful teaching, especially in large classes.The
sharp division of thebook
into descriptive psy-chology, physiological psychologyand dynamic
psychol-ogy
makes
some
difficulty in the selection of referencereadings. Strictly parallel readings are impossible in the case of
many
chapters. Itison
thewhole
best to followProfessor Titchener's advice
and
have the class firstmas-ter one coherent account of the subject
and
then read one ormore
other elementary text-booksand
later still, if there is time, parts ofsome
general treatise.A
list ofPreface for Teachers xiii
references for individual study of special topics is given
at the
end
of the book.Teachers Gillege, Ojlurabia University, January, 1905.
PREFACE
TO SECOND
EDITION
The
changesfrom
the first edition consist ofaltera-tionsof form, especially inthecase of the exercises,
which
theexperienceof teachers
who
have
used thebook
recom-mends.
The
content remains practically identical withthat of the first edition.
The
reference listsareimproved
by
the utilization of the psychological literature of thepast
two
years. Since an excellent English version ofthe fifth edition of
Wundt's
Physiologische Psychologieis
now
progressingtoward
completion, the references toit
have
beenchanged
to fit the fifth, instead of the fourth,edition.

Mental
FactsThe
world ismade
up
of physicaland
mental facts.On
theonehand
therearesolids, liquidsand
gases, plants,trees
and
the bodies of animals, the starsand
planetsand
their
movements,
thewinds
and
clouds,and
soon through
the list of physical things
and
theirmovements.
On
the otherhand
are the thoughtsand
feelings ofmen
and
ofother animals; ideas, opinions,
memories,
hopes, fears,pleasures, pains, smells, tastes,
and
soon through
thelist of states of mind. Physics, chemistry, astronomy,
botany, zoolog}-, geolog}'
and
the other physical sciencesdeal with the
former
group
of facts. Psychology-, thescience of mental facts or of mind, deals with the latter.
Human
psychology' deals with the thoughtsand
feelingsof
human
beingsand
seeks toexplain the factsof intellect, characterand
personal life.How
do
you
remember
where
you
were
a yearago?
Why
do
we
attend tocertain sights
and
soundsand
neglect others?What
is the diflFerence
between
an
intelligent pupiland
an
idiot?
What
decideshow
large one shalljudge an
ob-ject to be?
What
happens
when
a student reasons outa
problem
ingeometr}?
Such
are the questionswhich
the science of psycholog}' tries to answer.
These
questions center about four leading topics:
(i)
The
nature of the different kinds of thoughtsand
feelings.(2)
The
purposeswhich
they serve in life.(3)
The
ways
inwhich
they are related to the action ofthe brain or nervous system.
(4)
The
lawswhich govern
their behaviorand
that ofthe bodily states
and
acts connected with them.E.g., psychology should give information about:
—
(i) Just
what
attention is.(2) In
what
way
fear or pain is useful in the conductof life.
(3)
How
softening of the brain produces idiocy orhow
fever produces mental confusion.
(4)
Why
thinking of one thingmakes
one think of acertain other thing, or
why
practicemakes
perfect.Its task thus concerns the description of mental states
or processes, their function in nature, their relation to the
nervous system
and
the general explanation of the partplayed by the
mind
inhuman
life.Exercises

Which
of the four aspects ofpsychology does each of thedefinitions of psycholog\' given below emphasize?
a. "Psychology is the Science of Mental Life, both of its
phenomena and their conditions." (W. James).
b. . . .
"We
note their resemblances, diflFerences andother relations [the author is speaking ofthoughts and feelings]
and can thus coordinate them, place under one head those that
are alike, and give them a
name
by which to speak of them."(J. McCosh).
c
"What
these phenomena [thoughts and feelings] actuallyare, as conscious states and
how
they come to exist and followeach other in the order which they in fact assume, forms the
primary subject of the investigations of psychology." (G. T.
Ladd).
d. The science of psychology attempts "(i) to analyze
con-crete (actual) mental experience into its simplest components,
(2) to discover
how
these elements combine, what are the lawswhich govern theircombination, and (3) to bring them into
con-nection with their physiological [bodily] conditions." (E. B.
Titchener).
e. "The business of psychology is to furnish a systematic
and coherent account of the flow of psychical process in its
various forms, phases, and stages, and of the conditions on
which it depends." (G. F. Stout).

Classification ofMental
States.—
A
list of allthe different kinds of thoughts
and
feelings thathuman
beings
have
would
exceed in length a list of thehundreds
of thousands of animals
and
plants.For
conveniencepsychology' divides this total
group
of mental conditionsinto a
few
great classes.4
Introductionsympathy and
merriment, are alikeamong
themselves inthat each is a feeling, not of
something
in the outsideworld, but of
some
personal attitude or condition. All theseand
similar feelings aregrouped
together for study, thename
usedby
psychologists in referring to thegroup
being emotions.
When
you
closeyour
eyesand
callup
in imaginationyour
father's face, oryour
room
athome,
when
you
callup
the voice of a friend or themelody
of a familiar song,you
feel in each casesome
thing orcon-dition, but as not present. All such feelings of things,
qualities
and
conditions as not present aregrouped
to-gether forstudy
under
thename
mental images.To
take another instance, thesound
of a bell thatyou
hear in a dream, the faceswhich
the fever-patient sees in hisdelir-ium, the ghosts
which
still exist for the mind's eye,may
all be classed together since they are all feelings of
things as present
when
really nothing of the sort isactually present.
Such
feelings are called hallucinations.Some
of the chief groups intowhich
thoughtsand
feelings are classified are:
I. Sensations. 2. Percepts.
3.
Mental
Images.4.
Memories.
5. Feelings of
Meaning.
a. concepts or general notions. b. individual notions.
c. abstractions.
6. Feelings of Relationships.
7-
Judgments.
8. Emotions.
9- Feelings concerned in the direction of
conduct; states of will.
The
SubjectMatter
ofPsychology
5
these
groups
will bemade
clear in later sections.For
thepresentitwill besufficient to get a
rough
general idea of them. This can bedone
easilyby making
actual observations as follows:—
1. Sit near a hot stove.
Touch
yourself with a pencil.Bend
your
finger.Prick yourself with a pin.
Listen to the tap of a stick
on
the floor.Hold
abook
at arm's length for one minute.The
feelings ofwarmth,
touch,movement,
pain,sound, strain or fatigue
and
others likethem
are calledSensations. Sensations are feelings of qualities or con-ditions either of things or of one's
own
body.2.
Look
at a picture.Listen to a chord or melody.
Take
hold of a key.You
feel in each casesome
'thing' that is present.Such
feelings of things present are called Percepts.3.
Imagine
toyourself thetuneofYankee
Doodle,Imagine
the feeling of velvet.Imagine
the sightof themoon.
Imagine
thatyour
arm
isswinging back and
forth.
The
feelingsyou have
of the sound, the velvet, themoon
and
thearm-motion
are calledMental
Images.A
mental
image
is the feelingof a thingor quality orcondi-tion
when
it is really notthereand
is felt notto be there.4.
Think
what
you
were
doing
yesterday at oneo'clock.
Think
ofwhat
you
ate for dinner day beforeyesterday. Recall the feeling
you have
when
you meet
some
onewhom
at firstyou do
notremember
but finallyremember
ashaving
been withyou
at a certain place.The
term
memories
is also at times used to includemental images.
Thus
ifany
one calls tomind
theway
his father looks, he
may
be said either tohave
a mentalimage
of his father or toremember
his father.The
words
memory
and
remember
and
forget are also usedfor habits or matters of skill that are permanent.
Thus
we
say thatwe
remember
how
todance,swim
or play thepiano.
A
bettername
herewould
be 'thepermanence
ofhabits.'
5. If
you have
such thoughts as,'Eggs

there
may
be images of sight orsound
in connection withthe thought but they vary with different people
and
are not the important thing in the thought.The
importantthingisthe feeling of
your Meaning.
Thus, inthe fourth thought,you
feel thatyou
mean
all teachers,though
you
may
have animage
ofsome
one teacher, or of thesound
of the
word
'teacher,' or ofsomething
different.These
feelings of
Meaning
are very important in all highersortsof thinking.
When
the feeling is thatwe
mean
everyone of a class of things (e. g., 'all teachers', or 'girls')
the feeling is called a general notion or concept.
When
we
feel thatwe
mean
one particular thing (e. g.,when
we
think 'Shakspere' or 'Napoleon' or 'this apple') thefeel-ing is called an individual notion.
When
the feeling isthat
we mean

from
the thing or person possessing it, the feelingThe

We
feel not only qualities, conditions, objectsand
meanings, but also the relations
between
them. E. g.,look at
two
books, one ofwhich
is bigger than the other.You
feel not only the books, but alsotheir relation ofin-equality.
When
you
feel 'catsand
dogs'you have
notonly
two
general notions, but also the feeling that the things theymean
are tobe takentogether. 'Catswithoutdogs'
would
be felt tomean
something
quite different."Very important
among
such Feelings of Relationships are those of likenessand
differenceand
of causeand
effect.

you

The
nature of theEmotions
was
briefly describedin the second paragraph of § 2.
The
following list ofsample emotions
may

:—
Admiration,
amusement,
anger, annoyance, anxiety, awe,envy, fear, gratitude, hatred, joy, love, pity, regret, relief, remorse, restraint, revenge, self-complacency, shame,
shy-ness, sorrow, surprise, suspense, suspicion, sympathy,
wonder.
9. Notice
your
feelings of desire, choice, decision,effort, conflict, impulses
and
intentions.These
feelingsand
others concerned with action arecommonly
calledStates of Will, or Volitional States.
A
long list could bemade
of kinds of feelingswhich
fallmore
or less outside of these chief groups.E.g., there are feelings of attention, inattention, ennui,
Complex
Mental
States.—
No
absoluteand
sharpclassification can be
made.
It is not necessary or evenwise to
make
a cut-and-dried classification of all thoughtsand
feelings, since in the ordinary course of mental lifemixtures of different kinds of mental states are the
com-mon
occurrences. E.g., one thinks of aman
and
at thesame
time has feelings of attention to the mentalimage
and
of aversiontoward
theman, and
perhaps ajudgment
that he is dishonest.
Memory
image, attentiveness,emo-tion
and
judgment
thus combine.Nearly
all mentalstatesare pervaded
by
a feeling of selfhood,by
sensationsof one's
own
bodily conditionand by
a generalfeeling-tone of well-being or ill-being. It is, however, profitable in studying
human
nature to analyzecomplex
states ofmind
into theircomponent
parts, to study separately thesimpler aspects or parts of the total thought or feeling.
Intermediate
Mental
States.—
It is also true thatin the richness of an actual
human
mind's life there existvery
many
mental stateswhich do
not fall readily intoone class rather than another. E.g., is the
sound
of abell ringinga sensation or a percept, a feeling ofaquality or of a thing? Is the feeling of impatience an emotion
or a state of will? Shall the feeling of effort or strain
that one has as one holds the
mind
to a disagreeable taskbe called a sensation or
an
emotion? Just as there aresome
thingswhich
may
becalled eitheranimals or plants, just as there aresome
streamswhich
are equally wellclassified as brooks or as rivers,
—
so there are in mentallife intermediate,
halfway
stagesbetween
sensationand
perception, perception
and
image, vSensationand
state of will, etc. Itwould
be misleading to suppose that a man'smind was
by
nature dividedup
into anumber
of neatbundles, one of sensations, one of percepts,
and
the like,The

all the rest.
The
division is not absolute, but is like thatmade when
a cityis dividedintoa Chinese quarter,Italianquarter, Jewish quarter,
and
the like.The
divisionsgrade into each other imperceptibly.

GeneralView
ofHuman
ActionSince the majority of
human
actions are directly con-nected with thoughts or feeHngs, psychology deals with not only the mental states, but also the acts or conductof
men.
Conduct

Movements
and
Their
Connec-tions.
—
All acts are reducible tomovements
of thebody
brought about by the contraction
and
relaxation ofmus-cles.
The
common
notion ofan
act, however, includes, besides themere
act itself, the thoughtsand
feelingsleading to it
and
thecircumstancesunder
which
it occurs.Thus
we
commonly
regard Caesar's crossing theRubicon
as an act of unique importance, although the act itself
was
really only a series of alternate muscular contractionsidentical with the act of
going
to breakfast.The
mere
act of saying 'Yes' is the
same whether
it be a slice of bread or ahusband
that is accepted.The
million thingsa
man
doesfrom
birth to death are at bottom onlysome
thousands of
muscular
contractions.A

ofmovements

up
the infinite variety ofhuman
conductby

in different ways, causedby
different feelingsand

The

is mental statesand movements.
What
sort of a life it shall be dependsupon
: first,what
mental statesand
movements
compose
it,
and
second,how
these are connected.To
understanda
man's
intellectwe
must
know
not onlywhat

what

human
life fully,must
study not only mental statesand
bodily acts, but also their connections.The

which
stimulate the organsof sense, psychology
must
study also the connectionsbetween
(i) processes in the sense organsand
(2)men-tal states or

The
connections to be studied are then:—
(i) Connections
between
processes in the sense organsand
a thought or feeling,(la) Connections
between
processes in the senseor-gans
and
amovement.
(2) Connections
between
one thought or feelingand
another.
(3) Connections
between
a thought or feelingand
amovement.
E-g., feelinghot
when
one goes near the fire is a case of (i) : for it is a connectionbetween
the outside event, rapid molecular motion,and
our sensation of heat.The

One
might
expect to study also connectionsbetween

do
not arouse mental states or othermovements
directly,but only
by

Unlearned
and
Learned
Connections.—
Each
ofthese three divisions
may
be subdivided into:A.
Unlearned
or original or native connections.B.
Learned
or acquired connections.The
former are called instincts; the latter, habits.The
connectionbetween
ablow and
a pain is alreadymade
in us apartfrom
experience or training(lA),
whilethe connection
between
the presence ofthe lettersdog
on
a
page and
the thought of the familiar domestic animalhasto be acquired by experience, has to belearned (iB).
So
also for the connectionsbetween
a sweet tasteand
the act of sucking
(3A), and
the thought 'Ihave
onlytwo
minutes to catch the train'and
the act of running (3B).The
secondgroup
of connections are in nearlyall, if not in all, cases acquired.
That
between
thethought of the discovery of
America and
the thought ofColumbus
is a sample.Classes (i), (2),
and
(3)may
be called connections of Impression, Associationand
Expression respectively.There
are then:(lA)
Native or unlearned connections of impression.(iB)
Acquired
or learned connections of impression.( ?)
(2A)
Native orunlearned connections of association.(2B)
Acquired
or learned connections of association.(3A)
Native or unlearned connections of expression.(3B)
Acquired
or learned connections of expression.Each
of the six classes so farmade
could be subdivided again to almostany
extent according to the kind ofout-side events, mental states
and
bodilymovements
involved.Thus
(2R), acquired habits of association, could bedivided into associations between sensations
and
concepts,images
and
emotions, imagesand
images, emotionsand
The
SubjectMatter
ofPsychology
15In the case of class (3) it is useful to subdivide also
according to the extent to
which
the connection of the bodily act with the feeling is modifiedand
controllable.Some
connections (e. g., the contraction of the pupil of the eye in response to the brightness of the light) cannotbe altered. Others,
forming
the great majority, can(e- g., grasping certain objects in response to seeing them).
Further
Classification.—
The
followingnam€s
usedin psychology books for certainkinds of connections
need
explanation either because they are technical terms or are
common
words
used with a specialmeaning:
—
Reflexes,Instincts, Habits, Powers, Capacities, Associations of
Ideas, Inferences, Reasonings.
Reflexes include those connections of events in the
body,
—
sometimes felt in sensation,sometimes
not,—
withmovements,
inwhich
the act follows the impressionauto-matically, without either intention or control
on
our part{e. g., turning in the toes
when
the sole of the foot istickled, the contraction of the pupil of the eye in response
to light, or sneezing
when
themembrane
of the nose isirritated).
Instincts, as
now
commonly
defined, include reflexesand
all other connections or tendencies to connectionsamongst
thoughts, feelingsand
actswhich
are unlearned,—
are in us apartfrom
trainingor experience.Anything
thatwe
do
withouthaving
tolearn todo
it, in brief, isanmstinct. Thus, crying
when
pain isfelt, startingatasud-den noise, feeling fear at large, strange,
moving
objectsseen in the dark, feeling anger
when
food is snatchedaway
from one and
laughingwhen
tickled, are instinctsof
babyhood
; to feel jealousywhen
rivalledby
one ofthesame
sexand
to act conspicuouslywhen
attractedby
one of the opposite sex, are instincts of youth.The
common
usage of the
words
instinctand
instinctive differsfrom
the psychologist's usage. People
commonly
say thattheydo
or feel certain things instinctivelywhen
they act or feel without deliberation or forethought or clearcon-sciousness of
what
orwhy;
e. g.,"He
instinctively lifted the glass to his lips.""By
instinct I realized that theonly
way
of escapewas
directly through the fire."Neither of these cases
would
be called instinctiveby
the psychologist.For
tohim
an instinctmeans
an act thatis the result of
mere
inner growth, not of training orexperience.
Habits.
—
Tendencies to respondwhich
are created inwhole
or in partby
experience, practice or training arecalled Habits.
The
instinctive tendenciesbecome
habitsas soon as experience alters them. Practically all of
human
behavior is a series of illustrations of habits. Incommon
talk theword
is used only of tendencies tore-spond
which
havebecome
I'cry frequentand
I'cry habitual,such as eating three meals a day, taking off our clothes
when
we
go
to bed,bowing
to acquaintances, thinkingfour
when
we
see 2-)-2,and
the like.Rut
the essentialnature of the behavior is the
same whether
the habit ispartially
formed and
rarely used or fullyformed
and
always used. Indeed, for psychology every tendency for
anything to
go
with anything else is cither a case of apure instinct or of habit.
Poivcrs.
—
Habits not in action and possibilities of forming habits arc called Powers.For
instance, thatman
has thepower
to avoid theftwho
would
be habituallyholiest, though tcmjited, or
who
will habitually,when
temptecl. not thieve.
Capacities.
—
The
inborn qualities which arc the partialbasis for the develo])inciit of mental
powers
might
beThe
SubjectMatter
ofPsychology
17being qualities
which
will result in the presence of thepowers
or habits corresponding tothem
when
the propercircumstances arise.
The
common
word
for thesein-stincts of possibility is Capacities.
Thus
the capacity forcomposing music
means
the qualities which,though
them-selves
unknown,
will,when
the proper opportunity comes,blossom out into the
power
tocompose music and
the habit of doing so.Associations of Ideas.
—
Those
habits of thoughtby
which
any
one state ofmind
tends tocallup
another stateof
mind
are called Associations of Ideas.Thus
we
should say that the thought of
AB
callingup
the thoughtof C, or the thought of
90
degrees callingup
the thoughtof heat or of a right angle,
were
cases of the associationof ideas, or,
more
clearly, of habits in the realm of ideas.Inferences.
—
When
one
thought orjudgment
callsup
another leading
on
tosome
related conclusion the processis called an Inference. Thus,
whereas
we
would
call thesequence, 'John is sick. I like John,' a
mere
associationof ideas,
we
should regard asan
inference the sequence,'John has the measles.
Fred
has been playing with him.Fred
will probablyhave
the measles.'A
series of suchdirected thoughts or inferences is called
Reasoning
orRational Thinking.
In general the
term
Situation is used forany
total setof circumstances in the outside
world
and
in one'sbody
by which
themind
is influenced; Stitnulusis used forany
particular part of a situation; Reaction
and
Response
areused for the act,

sometimes for the mental state, that occurs as a result of the stiijiulus.Exercises

§ 5.
The
Nature
of SensationsDefinitions.
—
The word
Sensations is usedby
writ-ers of psychology with several different meanings.
Sometimes
they includeunder
thisterm
only feelings ofbrightness, color, size, pitch, loudness, timbre or
tone-quality, taste, smell, touch, pressure, resistance,
move-ment, heat, cold, pain, position, rotation, hunger, thirst
and
other feelings of definite qualities of thingsand
wellknown
conditions of the body.But
often they includealso the feelings of fatigue of different sorts, of effort or
strain, of suspense or expectancy, of shock, shuddering,
trembling, well-being, malaise, dizziness
and
otherfeel-ings of
vague
and
little understood bodily conditions.Ordinarily they include only the simple, bare,
uncom-bined feelings
under
the term sensationand
treat the actualcomplex
feelings (e.g., of the taste of amouthful
of acid, the smell of the
woods
or the touch of a pin, asmixtures or combinations of simpler elementary feelings.
But
they also use theword more
vaguely for all directfeelings of the qualities of things or of conditions of the
body which
are not the definite feelings of things classedas percepts or the richcombinations of feelings classed as
emotions. This being the usage, the
complex sound
of acity street, thetasteof coffeeor theshockof a coldplunge
would
be called a sensation. Sensations aresometimes
defined as the primitive, bare elements ofmental life, the first things in consciousness.
From
this point ofview
only the original appearance of
any
feelingmay
be called sensation; after that the mental state equals sensation plus association or experience.The
fact of importance that appearsfrom
these va-rious definitions, is that theyand
all others are arbitrary, that in factwe
cannotdraw
clear lines of distinctionbetween
sensations of qualities of thingsand
sensationsof bodily conditions,
—
between
sensationsfrom
special,well-known
stimuli like soundsand
from
vague,ill-known
stimuli like the condition of the blood or thegnawings
of dyspepsia,-—
between
atomic, indivisible bitsor brightness or pain or bitter
and complex
masses ofcolor, toothache or tones,
—
between
the first sensation ofany
sortand
the subsequent ones modifiedby
it.Nor
can
we
draw
a clear linearound
sensations (taken inthe broad sense
shown
by
thegroup
of samples above) soas to infallibly separate sensations
from
percepts orfrom
emotions or
from
certain feelings of relationships. It isindeed as important to
know
that these mental statesshade off the one into the other as to
know
the general features of differencewhich
lead us to separatethem
intogroups.
Feelings of
Things
as Present 21may
say that sensations are direct feelings of qualities of things or of conditions of the body.Pure
sensations aresuch feelings
when
uninfluenced by previous experiences.Elementary
sensations are such feelings so simple orminute as to be unanaly::able into simpler ones.
Pure
Sensations.—
Except
in the first experiences of early infancy, pure sensations are not found.The ways
in
which
the outsideworld and
ourown
bodily states arefelt are the result of original tendencies
combined
withpractice.
Thus
artistswho
wish
to getback
to the bare,immediate sizes
and
colors of things, apartfrom
the influence of our habitual interpretations of them,have
toundergo
special training to free themselvesfrom
the, fortheir purposes, disadvantageous tendencies of experience.
Although
in actual mental life pure sensations are notfound, it is possible in thought to regard
any
sensation as apure sensation plus the modifications in itdue
to experi-ence,and
toargue
about the pure sensation's factor orshare or aspect
by
itself.Elementary
Sensations.—
Elementary
sensationsare not real fragments of our mental states, but
abstrac-tions invented to aid our understanding of mental life.
They
exist inthe sense that lines without breadth orthick-ness exist. Just as an actual
boundary
wall is not asum
of such lines, so the sensations
we
have
are notsums
orcollections of tiny atomic sensations.
An
intense salttaste is not the
sum
of a thousand slightlysalt tastes,any
more
than the thought of a chair is the thought of c plus the thought of h plus the thought of aand
so on.Our
feelings of the outside world can in thought be analyzed
intoelements ofcolors, sounds, pressures
and
thelike, butin actualexperience they are felt as
