Inhibitory forces . In the dynamics of action model, inhibitory forces were negative forces that dampened and delayed the tendency to engage in an activity. Fear of failure is an inhibitory force related to achievement activities. A person with a high fear of failure will take longer to start studying than another person who has no fear of failure. Fears can be set through the user interface.
Environments also have negative presses that accentuate the effects of fears.
In the dorm room, the inhibitory force related to fear of failure and to studying is weighted highly by this high negative environmental press. Inhibitory forces for each activity are a function of the person's fears and the negative environmental presses. Consummatory forces . In the dynamics of action it is assumed that an activity will not continue indefinitely because satisfaction will occur as the result of engaging in the activity. Eating will bring about the cessation of eating.
