This organ imparts the power of continuity of thought. It also aids in
enabling its possessor to continue the action of the organs generally.
Predominant.--One having Concentrativeness predominant, with Causality
large, will be much subject to absence of mind. He will be quite unable
to attend to more than one thing at a time, and will be generally
prolix in conversation.
Large.--With large Concentrativeness, an individual will be much
disturbed if more than one thing claim attention at once; has a
strong inclination after taking up a subject to pursue it till he has
completed it. In conversation he will be much distracted if it is
desultory in its character. If a writer, his compositions will exhibit
a sustained unity of expression throughout.
Moderate.--One with Concentrativeness moderate, is inclined to pursue
a subject or train of thought, but can be easily diverted from it. If
Causality and Intellect generally are moderate, is neither inclined to
pursue a study to its termination, nor is he able to pass rapidly to
another. With nervous temperament he will possess great versatility of
attention.
Small.--With Concentrativeness small, an individual will be quite
unable to devote his attention for any length of time to a single
study or subject. In ordinary conversation, he will fly from one
subject to another, without order or arrangement. His friends, even if
strongly attached to them, will not be long thought of at a time. His
antipathies will be readily assuaged. He will possess great vivacity of
disposition.
