Abductive Reasoning
Abductive reasoning refers to the way we derive explanations from facts (Hill 1995:21; Dix 1998:40). Essentially, abduction involves us trying to find the causes of or explanations for things we see. Let us suppose that Bob always walks to work when his car is broken. If we were to see Bob walking to work one morning, we might infer that his car is broken. As plausible and possible as this may seem, it is unreliable be- cause Bob may simply have decided to walk to work because he wants to get more exercise. Despite the fact that abductive reasoning is very unreliable, people fre- quently infer explanations using this method. Indeed, beliefs acquired using this method will persist until events occur to show that an alternative is true Theoretical Approaches to Problem-Solving There have been numerous theoretical approaches to problem-solving over the decades but the most influential approaches are, perhaps, the stimulus- response approach, Gestalt theory and the information processing approach (Ellis & Hunt 1993:287; Gavin 1998:104). 140 (compare with vicarious reinforcement on page 134). Reasoning & Problem-Solving Stimulus-response Approach This approach assumes that learners approach problems with a number of existing habits of varying strengths arranged into habit-family hierarchies. Based on the principle of habit formation, this approach maintains that cer- tain habits are used to tackle problems at the expense of other habits; the p enough evidence to prove reliable. Gestalt Theory The Gestalt theory rests on the fundamental assumption that the way peo- ple solve problems depends on how they perceive and structure their prob- mans’ ability to reorganise and recombine their perception of the problem allows problems to be solved. This approach identifies four stages in prob- lem-solving (Ellis & Hunt ibid. ; Gavin 1998:105): preparation , incubation , illumination and verification . Gestalt theorists such as Wertheimer (1959) maintain that problem-solving is both a productive and a reproductive process. Reproductive thinking draws on or reproduces previous experi- ence while productive thinking involves restructuring, insight and the crea- tion of new organisations or Gestalts (Dix 1998:44; Gavin ibid. ). Preparation A person gathers information and makes initial attempts to solve the problem. Incubation The problem is left for a while and other tasks are car- ried out. Illumination The solution occurs to the person suddenly after incuba- tion. Verification The solution is checked to see that it actually works. Table 2: Stages in Gestalt approach to problem-solving Gavin ( ibid. ) makes the point, however, that because Gestalt theories are based on introspection, there is insufficient proof that all of these stages oc- cur in all cases. Consequently, such theories “lack the comprehensiveness necessary for a good theory” (Ellis & Hunt ibid. ). While Gestalt theory ul- timately proved unsatisfactory in terms of explaining problem-solving, it 141 roach, like that of the Gestaltists is internalised and does not provide chosen habits are strengthened while the others are weakened. This ap - lem environment (Ellis & Hunt 1993:288). Gestaltists maintain that hu Understanding Users did prove useful because it marked a shift away from previous stimulus- response approaches (Ellis & Hunt ibid. ) and towards the information- processing theory which is now so prevalent.
