Vroom developed a simple model of performance that divides ability and motivation. Using this model, two categories emerge, those that influence our capacity to respond and those that influence our will or desire to respond. The desire to respond includes what kinds of factors?

	variables dealing with employee motivation
	employee abilities and skills, personality variables, and work values
	culture and cultural diversity and job attitudes
	mental and physical abilities, personality traits, perceptual capabilities, and stress-tolerance levels
