BEHAVIOURAL PROCESSES
A borderline area between mental processes and material processes is represented by behavioral processes such as cough, sneeze, yawn, blink, laugh and sigh, which are usually one-participant. They are considered as typically involuntary; but it may be that there is a very slight agency involved. They can be deliberate, too, as in he coughed discreetly, he yawned rudely, in which the adjunct of manner implies volition. Acting excepted, most volitional adjuncts could not be used with die, collapse and grow, which are typically lacking in agency and volition.
We have already seen that mental processes such as see and hear have behavioral counterparts (watch and listen, respectively), which are dynamic and volitional, and have agentive Subjects, while see, taste and feel have both non-volitional and volitional senses. Similarly, think (in the sense of ponder) and enjoy can be used dynamically:
What are you thinking about?
I am enjoying the play enormously.
Enjoy!
