Introductory and Physiological.

Cerebral localization; Wundt, Waller.

Neural reinforcement

(facilitation) and inhibition; "Bahnung" and "Hemmung": Exner.

CHAPTER II.

Descriptive Theories of Attention.

Classification of theories as descriptive and explanatory. De-

scriptive theories of attention as motor, sensory and sensori-motor.

I. Motor theory: Ribot. Three criticisms of Ribot's theory:

motor phenomena concomitant but not constitutive; attention to

abstract ideas; the "idea of movement." II. Sensory theory. Ma-

rillier; movement and sensation; movement and attention. Sully,

Bastian. Correlation of consciousness with efferent nerve currents

in the cortex: Bastian, James, Wundt and Münsterberg; Marillier,
Sully, Fouillée and Waller. III. Sensory and motor, or sensori-
motor centres in the cortex; Mott, Waller; conclusion.

CHAPTER III.

Explanatory Theories of Attention.

Three types: I. Attention as facilitation, G. E. Müller. II. At-

tention as inhibition. Wundt: clearness; Thätigkeitsgefühl; inhibi-
tion; criticisms by Kohn; strain sensations, and associative co-ex-
citation. Külpe; outline and criticism. III. Attention as combined
facilitation and inhibition. Exner: physiological schemata; effect
of direction of attention to sense-impressions; recognition of in-
tensity due to attention, and due to stimulus. Attentional facilita-
tion and inhibition. Restatement of opposition between theories
it and Exner. Function of frontal lobes, Bianchi.
