    • n activity In. psychology, a self-determination of mental process, experienced or inferred, especially characteristic of the conative consciousness. The term has been variously and loosely used in modern psychology. In those systems which are still dominated by philosophical influences it denotes a primary and irreducible experience of self-causation or free initiative. To the psychologist who looks upon mind as a system of organic functions activity is given with the direction of the course of consciousness, knowingly or unknowingly, upon a determinate end: a particular mental process is the first term of a definite series, the remaining members of which it evokes in their order, while the series reaches its natural conclusion when the end is attained. In this sense, however, mental activity becomes practically synonymous with mental function itself, since the limiting cases of anoëtic sentience and involuntary movement are still self-determined in just so far as consciousness is in volved in them. Lastly, there are psychologists who, investigating mind as a stream of mental processes, predicate of it neither activity nor passivity, but hold that the autithesis of active and passive has no more place within psychology than the antithesis of subjective and objective. However, they still employ the terms, in obedience to traditional usage, as descriptive names of mental states or mental complexes; they speak, for example, of ‘active’ attention, meaning attention that is equiv rally conditioned; and of a ‘feeling of activity’ which accompanies the state of active attention. Such a terminology, however harmless in intention, can only add to the existing confusion.
