vision-- Waugh's food-box method--Results of tests--Tests by the use
of colored papers in the visual discrimination box--Yellow-red
vision--Blue-orange vision--Brightness vision versus color
vision--Brightness check tests--Green-blue vision--Violet-red
vision--Conclusions.
CHAPTER X
THE SENSE OF SIGHT: COLOR VISION (_Continued_)
The use of color filters--Testing color vision by the use of transmitted
light--Green-blue vision--Green-red vision--Blue-red
vision--Stimulating value of different portions of the spectrum--Does
red appear darker to the dancer than to us?--Conclusions concerning
color vision--Structure of the retina of the dancer and its significance.
CHAPTER XI
THE ROLE OF SIGHT IN THE DAILY LIFE OF THE DANCER.
Sight and general behavior--Behavior of blinded dancers--Experimental
tests of ability to perceive form--Visual guidance in mazes--Following
labyrinth paths in the dark--The relative importance of visual, olfactory,
and kinaesthetic stimuli--Conditions for the acquisition of a motor
habit--Conditions for the execution of an habitual act.
CHAPTER XII
EDUCABILITY: METHODS OF LEARNING
The modifiability of behavior--Educational value of experimental
studies of modifiability--Methods: the problem method; the labyrinth
method; the discrimination method--Relation of method to
characteristics of animal-- Simple test of the docility of the
dancer--Lack of imitative tendency-- Persistence of useless
acts--Manner of profiting by experience--Individual differences in

initiative.
CHAPTER XIII
HABIT FORMATION: THE LABYRINTH HABIT
The labyrinth method--Problems--Preliminary tests--Comparison of the
behavior of the dancer in a maze with that of the common
mouse--Evolution of a labyrinth method--Records of time and records
of errors--Simple and effective method of recording the path--Curves of
habit formation--Regular and irregular labyrinths--Points for a standard
labyrinth--Values and defects of the labyrinth method.
CHAPTER XIV
HABIT FORMATION: THE DISCRIMINATION METHOD
Quantitative versus qualitative results--Motives--Precautions--
Preference--Results of systematic habit-forming experiments--Curves
of habit formation--Meaning of irregularity in curve--Individual
differences--Comparison of curves for discrimination habits with those
for labyrinth habits--Averages--The index of modifiability as a measure
of docility--Reliability of the index.
CHAPTER XV
THE EFFICIENCY OF TRAINING METHODS
Importance of measuring the efficiency of educational
methods--Rapidity of learning and permanency of modifications
wrought by training--Results of a study of the efficiency of
discrimination methods--Comparison by means of indices of
modifiability--Number of tests per series versus number of
series--Efficiency as measured by memory tests.
CHAPTER XVI

THE DURATION OF HABITS: MEMORY AND RE-LEARNING
Measures of the permanency of modifications in behavior--The
duration of brightness and color discrimination habits--The relation of
learning to re-learning--Can a habit which has been lost completely be
re-acquired with greater facility than it was originally
acquired?--Relation of special training to general efficiency--Does the
training in one form of labyrinth aid the dancer in acquiring other
labyrinth habits?
CHAPTER XVII
INDIVIDUAL, AGE, AND SEX DIFFERENCES IN BEHAVIOR
Individual peculiarities in sensitiveness, docility, and initiative--The
relation of docility to age--The individual result and the average--How
averages conceal facts--Sex differences in docility and initiative--
Individual differences of motor capacity which seem to indicate
varieties--Is the dancer pathological?
CHAPTER XVIII
THE INHERITANCE OF FORMS OF BEHAVIOR
Characteristics of the race--Inheritance of the tendency to whirl in a
particular way--Tests of the inheritance of individually acquired forms
of behavior.
