Linda Gottfredson:
"All tasks in life involve some complexity, that is, some information processing. Life tasks, like job duties, vary greatly in their complexity (g
loadedness). "
-----
"Differences in g loading seem to arise from variations in items’ cognitive
complexity and thus the amount of mental manipulation they require."
-----
"The terms used in different conceptions of task complexity connote a grounding in information-processing demands: multiple alternatives, inexact means-ends, interrelated and conflicting subtasks, uncertain or unknown outcomes, information load and diversity, and rate of change. The various definitions tend to
stress the number, variety, variability, ambiguity, and interrelatedness of information ... - that must be processed to evaluate altematives, make a judgment, and reach a decision."
-----
"Life is replete with uncertainty, change, confusion, and misinformation, sometimes minor and at times massive. From birth to death, life continually requires us
to master abstractions, solve problems, draw inferences, and make judgments on
the basis of inadequate information."
-----
"workers are
confronted with novelty, change, uncertainty, unpredictability, and the need to
spot and master new information and emerging problems."
-----
"dealing with people is always fairly complex. This
should not be surprising, because other individuals are among the most complex,
novel, changing, active, demanding, and unpredictable objects in our environments, Living and working with others is a complicated business."
-----
Arthur Jensen:
"People's environments, or their perceptions of them, differ in complexity and cognitive demands. One might even characterize different environments in terms of their g loadings."
