COGNITIVE STYLE AND PERFORMANCE
Cognitive Continuum Theory (Hammond et al, 1987) offers a framework for linking cognitive style to task performance. All tasks and problems can be located on a continuum of structuredness (see Figure 1). At one end are unstructured tasks for which there are no widely accepted decision rules or objective criteria of success. Laughlin (1980) refers to these as ‘judgemental tasks’. Often they involve behavioural, political, ethical or aesthetic judgements. At the other end of the continuum are ‘intellective tasks’ that involve a definite objective criterion of success and to which well established decision rules can be applied. Examples of intellective tasks include calculating volumes, assessing costs or solving quadratic equations.
